'It is also very useful in providing a chromium-free coating body with good processability. [Knowledge technology] In recent years, with the high performance and miniaturization of electronic, electrical, and optical equipment, there have been problems such as increased heat generation (higher temperature) and higher heat generation in electronic equipment and other cases (electronics) High heating inside the machine). This paper size is subject to Chinese National Standard (CNS) A4 ^ (210X29 * 7mm) Ministry of Economic Affairs Zhi Shilu: Industrial and Consumer Cooperatives Disaster 1225826 A7 B7 V. Description of the Invention (2) It was pointed out that the electronic machine The internal temperature is about 40 ~ 70 ° C under normal ambient temperature, and the highest temperature is about 100 ° C. Because it exceeds 1C 'heat resistance temperature of CPU (semiconductor element), magnetic sheet, motor, etc., it will affect stable operation. Cause obstacles. In addition, if the temperature rises, it may cause damage to semiconductor components, failures, etc., which shortens the life of electronic device parts, which may cause such problems. Therefore, as a heat dissipation means for reducing (radiating) the internal temperature of electronic equipment, it has been proposed to install a radiator or a heat pipe on the casing of the electronic equipment (chassis body, frame, shielding case, back panel of liquid crystal, etc.) And other methods of cooling parts. However, in this method, at best, the effect of diffusing the heat emitted from the heat source (heating body) inside the electronic device into the entire casing is obtained, especially when the volume of the casing is small, the desired heat radiation. In addition, the installation of such a heat-dissipating component is labor-intensive, it is necessary to secure a place for installation, and there are problems such as an increase in cost. Therefore, it is not suitable for use in electronic devices that are miniaturized and reduced in cost. In addition, a method has also been proposed in which a metal plate (coated body) is used in a housing of an electronic device, a hole is provided in the metal plate to install a fan, and heat is radiated by convection. However, electronic devices are generally less resistant to water and dust, so they are difficult to use depending on the application. In addition, as with the above-mentioned radiators, etc., there are some aspects that increase the cost of the product, take time to install, and ensure installation space. problem. Therefore, it is desirable to provide a new type of electronic device structure paper that meets the original characteristics of electronic devices (ensures airtightness, miniaturization, and weight reduction along with waterproof and dustproofing) and reduces the internal temperature (heat dissipation characteristics) of the electronic device.

On the other hand, in addition to the above-mentioned heat dissipation characteristics of electronic equipment enclosures, it is also required to be able to suppress the temperature rise of the enclosure itself. This is because, during the operation of the electronic equipment product, it is possible to prevent consumers from contacting the casing with danger of burns and the like, and to provide safe products. In order to distinguish this "characteristic of suppressing the temperature rise of the housing of the electronic device itself" from the "radiation property" described above, in the present invention, it is called "self-cooling property". When preparing these two kinds of casings with excellent characteristics, the same problems were still found by using the above-mentioned heat dissipation methods (methods of installing heat-dissipating parts such as radiators or heat pipes, or methods of providing holes in metal plates, and methods of installing fans). Therefore, it is desirable to provide a housing having these two characteristics. In addition, in addition to the above-mentioned characteristics, a housing of an electronic device is required to have excellent electrical conductivity. However, the thickness of the black coating film such as the black coating steel plate (steel coated steel plate) used today is too thick, the resistance 値 becomes very high, and it cannot be grounded when it is used in electronic equipment. Ministry of Economic Affairs / T7a (Industrial and Industrial Cooperative Cooperatives) In addition, for the substrate side, conventionally, the substrate was chromated from the viewpoints of corrosion resistance and coating film adhesion, but due to its large use Harmful hexavalent chromium, so the problem of environmental pollution is very serious. Therefore, instead of harmful chromate treatment, it is required to find non-chromate that does not contain chromium. Treatment methods. However, it is known that when chromate treatment is not performed , Its corrosion resistance, coating film adhesion, and processability are very poor. Therefore, it is desirable to provide a non-containing material that is excellent in corrosion resistance, coating film adhesion, and processability even without chromate treatment.

In order to provide the original characteristics required by the electronic device (ensure airtightness, miniaturization, light weight, low cost, etc., such as waterproof and dustproof), the inventors can reduce the internal temperature of the electronic device (heat dissipation characteristics) ) A new type of coating body for electronic device components, especially for improving the heat dissipation of the coating body itself. As a result, it was found that if a predetermined coating film was coated on the front and back surfaces of the substrate, the desired purpose could be achieved. Printed by the 8th Industrial Cooperative Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs ^ The mechanism of action is: "The heat is absorbed (radiated) from the heat source (heating body) inside the electronic device with the coating film on the back, and the heat is removed from the surface. The biggest feature of the "heat-radiating coating film is to radiate out" is the clever use of the so-called "heat-passing method" in electronic machine components. Applying this "thermal passage" idea to electronic device components, the heat emitted from the electronic device is absorbed from the "back surface of the substrate" to the "surface of the substrate"-the coating body that radiates it is currently not human Known, it is new. Next, before describing each coating body, the relationship between the first coating body (a coating body having excellent heat dissipation properties) and the second coating body (a coating body having excellent heat dissipation properties and self-cooling properties) is performed. Instructions. The first coating body and the second coating body apply the above-mentioned "Heat Pass This Paper Standard to China National Standard (CNS) A4 Specification (210X297 mm) 1225826 A7 _B7 V. Description of the Invention (^) 13 (Please read the precautions on the back before filling out this page) The basic idea is the same for the idea of improving the heat dissipation of electronic machine components. However, the problems that the two are trying to solve (mainly solving problems) and the technical ideas and structures used to solve the problems are different. That is to say, the first coating body was revealed to solve the problem of maximizing heat dissipation (decreasing the internal temperature of electronic equipment). Based on the "the higher the product of infrared emissivity on the front and back, the better" The idea is to determine the structure of the heat-dissipating coating film by using the front and back surfaces as an integral part of the heat-dissipating coating film; the opposite 'second coating body is to maintain the heat-dissipation characteristics to a certain degree by using the "thought of heat passage" and " In order to suppress the temperature rise of the coating body itself, the biggest solution is to solve the problem. According to "the infrared radiation rate of the back surface is set to be different, the infrared radiation rate of the back surface is lower than that of the surface, and the infrared radiation rate of the surface is reduced. The idea of making the heat absorbed by the coating body as high as possible, and controlling the composition of the coating film on the front surface and the back surface, respectively, can be regarded as inventions with different directions of purpose. Printed by the Consumer Finance Cooperative of the Ministry of Economy ’s Smart Finance Bureau [that is, the first coating body is excellent in heat dissipation, but it is self-cooling The type with poor performance.

Description of the invention (14) In addition, compared with the back surface, the surface has a higher infrared radiance, so it is 'excellent in self-cooling properties'. This part is a region with excellent heat dissipation characteristics and self-cooling properties. Next, each coated body of the present invention is subjected to Instructions: (A) Heat dissipation Excellent coating body for electronic device components (first coating body) The first coating body of the above formula is produced based on the above-mentioned basic idea. It was found that if a predetermined heat-dissipating coating having heat-dissipating properties is coated on the front and back surfaces of the substrate, The film can be used to achieve the desired purpose. That is, the first coating body is used as a coating body for an electronic device member by using the surface and the back surface of the substrate. [In the present invention, From the perspective of the coating body, the outside air side is called the "surface", and the inside of the coating body is called the "back surface". The integrated emissivity is covered with an arbitrary infrared wavelength range (wavelength: 4.5 to 15.4 // m). It is a coating body of a heat-radiation coating film that satisfies a predetermined range of "infrared integrated emissivity" or "infrared emissivity", and has a technical idea of ensuring excellent heat dissipation. Incidentally, as conventional coating bodies, for example, a post-coating material that is coated after processing such as pressing processing, a pre-coating material that is coated before processing, etc., but they are not completely like In the present invention, the idea of "using the heat-passing method to improve heat dissipation when used as a housing for an electronic device member" does not cover the front and back surfaces of the substrate with a heat-dissipating coating film having a predetermined heat-dissipating property.

On the other hand, the back surface (inner surface of the coating body) is not painted, or even if it is painted, it is generally only painted to ensure a minimum degree of corrosion resistance (therefore, the required heat dissipation characteristics cannot be obtained). Therefore, with such a single-sided coated body, the required heat dissipation characteristics cannot be obtained, and this is confirmed by the examples described later. Hereinafter, the said coating body is demonstrated concretely. The first coating body is covered with a heat-dissipating coating film on the front and back surfaces of the substrate.

The Ministry of Economic Affairs's “Smart” / itirs (Industrial and Consumer Cooperatives Co., Ltd. “Ax b” is defined as the product of the emissivity of infrared rays emitted from the coating body, which is used as an indicator to show the heat dissipation effect of the coating body. Another On the other hand, ΔΤ1 is defined as a practical level of heat dissipation effect that simulates the use of electronic device components. The ambient temperature set according to the application can be evaluated (the ambient temperature varies according to the type of electronic device, etc., which is approximately 50 ~ 70 ° C, the highest The heat dissipation characteristics at about 100 ° C) are adopted in the present invention. Both of the above are effective indicators for showing "heat dissipation", and have a good correlation. For reference, the examples described later will be described below.

It is extremely useful to accurately evaluate the heat dissipation effect at a practical level for simulating the use of electronic equipment.

Therefore, a heat dissipation evaluation device including the device shown in FIG. 1 is also included in the scope of the present invention (described later). -19- (Please read the precautions on the back before filling out this page) Printed by the Ministry of Economic Affairs, Intellectual Property Bureau, Industrial and Consumer Cooperatives This paper is printed in accordance with Chinese National Standard (CNS) A4 (210X297 mm) 1225826 A7 _ B7 V. Description of the invention (17) (Please read the precautions on the back before filling out this page) Figure 1 is a rectangular parallelepiped device with an internal space of 100mm (length) X 130mm (width) X 100mm (height). In the figure i, i represents the test material (measured body, measuring area is 100 × 130 mm), 2 represents thermal insulation material, 3 represents heating body [bottom area is 1 300mm2, the area of the heating body can be drawn The length of the longest straight line (the length of the diagonal line in the first figure) is l64mm], 5 represents the temperature measuring device. The Ministry of Economic Affairs and the Intellectual Property Office of the Ministry of Economic Affairs and Consumer Affairs Co., Ltd. printed% [Among them, the heating element 3 uses a structure in which a silicone rubber heater is used and an aluminum plate (infrared radiation rate below 0.1) is adhered to it. A thermocouple as the temperature measuring device 5 is fixed at the position T1 in the first figure [the central portion of the internal space (above 50 mm from the heating element)]. In order to eliminate the influence of heat radiation from the heating element, the lower part of the thermocouple is covered. Insulation material 2, depending on the type or use state, the ambient temperature inside the box changes (which also affects heat dissipation). Therefore, a metal plate with an infrared emissivity of 0.03 to 0.06 is used [for example, an electric zinc plate ( jIS SECC, etc.)], according to the method described later, adjust the tension of the thermal insulation material, etc., so that the ambient temperature (absolute temperature) at the T1 position is about 73 to 74 ° C. In addition, the factors that affect heat dissipation (such as the method of fixing the test material) are also adjusted so that the ambient temperature (absolute temperature) at the T1 position is about 73 ~ 74t :. The following is a description of the method for evaluating heat dissipation characteristics using the above device. ○ During measurement, in order to eliminate data deviation caused by external conditions (wind, etc.), the measurement conditions were controlled to temperature: 23 ° C, relative humidity: 60%.

After the temperature of the hot plate was stabilized at 40 ° C, after confirming that the temperature at the T1 position was 60 ° C or more, the test material was temporarily taken out. When the temperature in the box dropped to 50 ° C, the test material was placed again, and after the test, the temperature in the box was measured in minutes. Next, the difference between the temperature when the test material was used and the temperature when the uncoated original sheet was used without coating was calculated. In addition, ΔT 1 was measured 5 times for each test material, and the average 値 of the other three points from which the maximum 値 and the minimum 其中 were removed was determined as Δ D1 of the present invention. The larger the Δ T 1 calculated in this way, the better the heat dissipation characteristics. The preferred order is above 2.7 ° C, above 3.0 ° C, above 3.3 ° C, above 3.5 ° C, above 3.7 ° C, and above 4.0. In addition, the index (target level) of heat dissipation characteristics varies depending on the type of electronic device and the like, but according to the present invention, as described later, by controlling the black additive contained in the heat dissipation coating film appropriately according to the relationship with the thickness of the coating film, it is possible to Easily adjusted to the specified heat dissipation characteristics.

Therefore, the higher the above-mentioned infrared emissivity, the greater the thermal energy that is emitted (absorbed). For example, when 100% of the thermal energy imparted to an object (a coating body in the present invention) is radiated, the integral infrared emissivity is 1. In the present invention, the integral infrared emissivity when heated to 100 ° C. is determined. However, it is considered that the coated body of the present invention is used for electrical appliances (different due to components, etc., but the general ambient temperature is approximately 50 ~ 70 ° C, maximum 100 ° C), in order to be consistent with the temperature of this practical level, the heating temperature is set to 100 ° C. However, even if it is heated to 200 ° C, the infrared integrated emissivity is almost unchanged. The infrared integrated emissivity when heated to 200 ° C is about 0.02 higher than the infrared integrated emissivity of iOOt. However, it was confirmed by tests that they were almost the same (in addition, in the examples described later, the infrared emissivity when heated to 100 ° C and 200 ° C are both described).

As described above, the number (the product of the integral infrared emissivity emitted from the coating body) calculated using "ax b" is effective as an indicator of the heat dissipation effect of the coating body, and it satisfies the above formula. The package exhibits high radiation characteristics on average in the above-mentioned wavelength range. Therefore, the target of the heat dissipation characteristics of the first coating body is set to "ax 0.42".

Moreover, in the above-mentioned first coating body, as long as the target 値 of the heat dissipation characteristics is satisfied, the relationship between the surface infrared emissivity and the back infrared emissivity is not particularly limited, and the solution including the difference between the infrared emissivity of the front and back surfaces, and Both sides have the same degree of emissivity. On the other hand, the second coating body of the present invention differs from the heat dissipation property in that the self-cooling property is the main purpose of the second coating body. The coating body is limited to a coating body having a higher infrared emissivity on the surface than on the rear surface [described later] (B) is recorded].

A coating body having both sides of 0.65 or more is more preferable. In the first coating body, the spectral emissivity of the infrared rays (wavelength 4.5 to 15.4 // m) in any wavelength range is better. The difference (A-B) between the maximum 値 a and the minimum 値 B is preferably 0.35 or less. The "A-B" represents the range of change in emissivity in the above-mentioned infrared wavelength range, and "A-BS 0.3 5" means, that is, It can stably exhibit high radiation characteristics in an arbitrary range of the infrared wavelengths. Therefore, those satisfying the above points can be applied to applications such as electronic equipment equipped with various components emitting different infrared wavelengths, etc., and it is expected to expand in Application in electronic device components. Specifically, the arbitrary emissivity measured as described above is measured, and the difference (A-B) between the maximum chirp (A) and the minimum chirp (B) of the spectral emissivity in the wavelength range is measured.

The meaning of the above formula is that in order to ensure the "heat dissipation characteristics" determined in the first coating body, black additives such as carbon black must be appropriately controlled based on the relationship with the thickness of the coating film. (That is, increase the content of black pigment per unit thickness), and when the film thickness is thick, the content of black pigment can be reduced (that is, the content of black pigment per unit thickness is reduced), and the findings of the present invention are formulated.

According to the figure, in order to ensure the target heat dissipation characteristic (ax bg) of the heat dissipation characteristics disclosed by the first coating body of the above formula, 0.42, ΔΤ1 $ 2.6 ° C), the above formula P 値 must be above 15.

Formula (3): 4 96 ^ X < 1596 In the present invention, it is assumed that the content of the black additive X is 3% or more, and it is recommended to be 4% or more Here, the premise of "X > 3%" is because in order to satisfy the above formula (2), the coefficient (X-3) on the left side of the formula must be positive (> 0).

On the other hand, the upper limit of X is not particularly limited in the relationship with the heat dissipation characteristics, but if it is 15% Above, coating properties are deteriorated, uneven coating occurs, and appearance is poor. Therefore, a preferred upper limit in consideration of paintability and the like is less than or equal to 15%, 13%, and 11% in order.

While having good processability, in order to ensure excellent conductivity, it is recommended to control the above formula Y below 1 2 // m (in a better order, 11 // m or less, and more preferably i〇 // m or less). In the above formula (2), X (the content of the black additive) and Y (the thickness of the coating film) have been described.

Typical examples include carbon black, and Fe can also be used. , Co, Ni, Cu, Mn, Mo, Ag, Sn., Etc. oxides, sulfides, carbides or black metal fine powder. The best is carbon black. Here, the amount of carbon black added (X) in the coating film can be measured by the following method. First, a solvent is added to the test object (analytical sample) and heated to decompose organic substances in the test object. The type of solvent used is based on the size of the base resin and the size of the paper. Applicable to the Chinese National Standard (CNS) A4 (210X297 mm) ^ 29----- 1225826 A7 _____B7_ V. The type of invention description (27) is different, depending on the resin For the solubility, an appropriate solvent can be used. For example, when a polyester resin or a polyurethane resin is used as the base resin, a test object is added to a container (eg eggplant type flask) containing a sodium hydroxide-methanol solution, and the The container was heated in a 70 ° C water bath to decompose the organic matter in the test object. Next, the organic matter was filtered by a glass screening method (pore size 0_2 / zm), and the carbon in the residue was quantified by a combustion infrared absorption method to calculate the carbon black concentration in the coating film. The average particle diameter of the black additive is preferably controlled to 5 to 100 nm. When the average particle diameter of the additive is less than 5 nm, the required heat dissipation characteristics are not obtained, and the stability of the coating material is deteriorated, and the appearance of the coating is deteriorated. On the other hand, if the average particle diameter is more than 100 nm, not only the heat dissipation characteristics are reduced, but also the appearance after coating is not uniform. It is preferably from 10 nm to 90 nm; more preferably from 15 nm to 80 nm. In addition to the heat dissipation characteristics, if the stability of the coating film and the uniformity of appearance after coating are considered, the optimal average particle size of the black additive is recommended to be 20 to 40 nm. In addition, the type of resin (base resin that forms the heat-dissipating coating film) added to the coating film is not particularly limited from the viewpoint of heat-dissipating characteristics, and acrylic resins, urethane-based resins, and polyolefine-based hydrocarbon resins can be appropriately used , Polyester resins, fluorine resins, silicone resins, and their mixed or denatured resins. However, in order to use the coated body of the present invention as a housing of an electronic device, in addition to heat dissipation properties, if it is required to improve processability, the above-mentioned base resin is preferably a non-hydrophilic resin.

The resin that satisfies such non-hydrophilic characteristics can also be changed according to the degree of mixing or denaturation. For example, polyester resins, polyolefin resins, fluorine resins, silicone resins, and mixed or denatured resins are preferably used.

In the above coating film, in addition to black additives such as carbon black, pigments such as rust preventive pigments and silicon dioxide may be added within a range that does not affect the effects of the present invention. Alternatively, within the range not affecting the function of the present invention, one or two additives having heat dissipation properties (such as TiCh, ceramic, iron oxide, aluminum oxide, barium sulfate, silicon oxide, etc.) other than black additives may be added.

Painted steel sheets have been disclosed. For example, Japanese Patent Application Laid-Open No. 3-1 20378 discloses a manufacturing method of a far-infrared radiation plate (a ceramic layer having far-infrared characteristics is formed on a substrate) used in a heating device member, and describes "in a predetermined black color" Black pigments, such as carbon black, can be added to the acrylic resin film, thereby exerting far-infrared radiation characteristics; the addition amount is 0.1 to 100 parts by weight of the resin

Description of the invention (29) 10 parts by weight, the thickness of the resin coating is usually ol ~ 5 // m ”(please first (Please read the notes on the back and fill in this page) However, the far-infrared radiation plate described in the above publication only forms a ceramic layer on only one side of the substrate, and does not have the same effect on the substrate as the coated plate of the present invention. The coating film is formed on the back surface of the watch, so the required heat dissipation is not obtained. The Bureau of Intellectual Property, Ministry of Economic Affairs, 1st Bureau (printed by the Industrial and Consumer Cooperatives, because they use different objects (purposes), are considered as a basis for solving the problem. The components are also different. That is, the far-infrared radiating panel of the above-mentioned publication is a heating appliance (typically a heating furnace, etc.) that requires heat dissipation characteristics at a very high temperature of about 200 to 300 ° C. In the field, there is no such thing as the coating body of the present invention, especially for the electronic device components whose internal temperature is about 40 ~ 70 ° C at the normal ambient temperature and up to about 100 ° C. Therefore, in the above bulletin, the idea is only to increase the emissivity (radiance) of far infrared rays emitted from heating appliances such as heating furnaces as much as possible. For this reason, only carbon black was added, except for heating appliances. In addition, the so-called "heat-passing method" of "in order to reduce the internal temperature of an electronic device, the heat emitted from the electronic device is absorbed on the back surface of the substrate-the absorption and radiation of the surface of the substrate" is not generated at all. In fact, since the above-mentioned radiant panel is painted on only one side, when the integrated emissivity and the emissivity change range are adjusted under the conditions described in the present invention, it is confirmed through experiments that it cannot be obtained as in the present invention. Excellent heat dissipation characteristics (No. · 19 in Table 5 described later). In the above publication, a black coating was formed by using a Zn-Ni alloy plated steel plate as a substrate to form a black film, and then a black denim paper was coated on the upper layer. Standards are applicable to China National Standard (CNS) A4 specifications (210X297 mm) -32-1225826 A7 _B7_ V. Description of the invention (30) (Please read the note on the back first Please fill in this page for further details.) By using a lipid film, the far-infrared radiation characteristics in the high temperature range can be exhibited. However, if such a radiation plate is directly used for an electronic device component (and a far-infrared radiation plate) as an object in the present invention, It can be used in a much lower temperature range (compared to use), and has different characteristics depending on the application. Therefore, there are various problems. That is, electronic equipment components require more severe bending processing than thermal appliances. Therefore, cracks occur in the plating alloy layer. Starting from the cracks, impurities in the black resin film or plating will peel and fall off, resulting in poor appearance. If such peeling or peeling occurs inside the plating layer, The peeled film or electroplated impurities will adhere and accumulate on the parts of the electronic device, causing problems such as the failure of the electronic device. Therefore, the present invention is considered to be a different invention from the aforementioned radiation plate.

In the above-mentioned first coating body, at least one side of the heat-dissipating coating film coated on the front and back surfaces of the substrate mainly contains a black additive, but the other heat-dissipating coating film is not limited to this, in order to meet the required heat dissipation requirements of the present invention. Characteristics: In addition to black additives, heat-releasing additives (sometimes called "other heat-releasing additives") other than black additives can be added to form a heat-radiating coating film. Of course, both the front and back surfaces of the substrate have a coating body containing a heat-radiating coating film containing a black additive that satisfies the above-mentioned relationship.

Description of the invention (33) The 3 points of the upper and lower limits are averaged as ΛΤ2 in the present invention. Compared with the case of using a substrate (a bare original plate without a coating film), when the coated body of the present invention is used, the above-mentioned ΔΤ2 is determined as an index (self-cooling property) that can suppress the temperature rise of the coated body itself when the electronic device is operating. ), In the present invention, as a device for measuring ΔΤ2, the unique heat radiation evaluation device of the present invention shown in FIG. 1 is used. In order to obtain excellent self-cooling properties, the larger ΔT2 is, the better. The preferred order of △ T2 is 1.0 ° C or higher, 1.5 ° C or higher, 2.0 ° C or higher, and 2.5 ° C or higher.

Based on this finding, the present invention repeats various tests to determine the above formula. According to the present invention, the back surface of the substrate Compared with the absorbed (radiated) heat, the amount of heat radiated from the surface side of the substrate is increased, so it is possible to more effectively suppress the temperature rise of the coating body itself. In this way, a coating film with different heat dissipation characteristics is provided on the surface and back of the substrate. The level of heat dissipation characteristics is maintained to a certain extent, and the temperature rise of the coating body is also suppressed. This type of coating body was not available before and is new. Therefore, in the above-mentioned second coating body, the infrared emissivity of a and b The larger the difference, the better self-cooling can be obtained. Specifically, the larger Q Q (= 0.9a — b) is, the better, and the preferred order is 0.13 or more, 0.24 or more, 0.35 or more, and 0.47 or more.

Second coating body The index of the heat dissipation characteristics of [(a — 0.05) X (b-0 · 05)] on the left is larger (hereinafter sometimes referred to as R 値), the better the heat dissipation characteristics (ΔΤ1).

(Mm) Γ37 ^ 1225826 A7 B7 V. Description of the invention () (Please read the precautions on the back before filling out this page) Reduction is revealed as the main problem to be solved. As long as the problem is completed, the level of heat dissipation characteristics is based on Depending on the discovery including a slightly lower form than the first coating body Next, a specific structure for obtaining the second coating body will be described. The coating body is a coating film coated on the front and back surfaces of the substrate, and a heat dissipation coating having heat dissipation properties on at least the surface of the substrate. In order to ensure the required self-cooling property, it is necessary to satisfy the above formula (4) to increase the infrared emissivity of the surface compared to the back surface, and the heat dissipation characteristics must satisfy at least the above formula (5). In the coated body, in order to make the level of the required heat dissipation characteristics different from the front and back surfaces, the following description will be made on a case-by-case basis. First, the "surface heat-dissipating coating film" of the second coating body includes the following types (i) and (ii). (i) The black additive is mainly added, and the type of the black additive (X) contained in the heat dissipation coating film is controlled based on the relationship with the film thickness (Y) of the coating film. The black additive is added to the surface coating film to improve the heat dissipation characteristics. In the case of the Intellectual Property Office of the Ministry of Economic Affairs and Economics 3 (In the case of industrial and consumer cooperatives, in order to make the additive amount (X) and coating film thickness (γ) of black additives meet the following formula (6), X and Y can be appropriately controlled. Specific The following formulas are used: 〇 Formula (6): (X- 3) X (Y- 0.5) 2 3 The above formula (6) is to achieve the target of heat dissipation in the second coating body 値 (△ T1 ^ 1.5 ° C ) And the relationship between X and Y is determined, the larger P 値 [= (X-3) X (Υ-0 · 5)], the better the heat dissipation characteristics can be obtained. The better paper size applies the Chinese national standard (CNS) A4 specification (210X297 mm) 1225826 A7 B7 V. Description of the invention (36) The sequence is 7 or more, 11 or more, 15 or more, 30 or more, and 50 or more. (Please read the precautions on the back before filling out this page) However, even if P 値 is further increased, the heat dissipation characteristics are saturated, but the amount of black additives and the like used is increased, except for economic waste. If the coated body of the present invention is used as a housing of an electronic device, considering that processability or electrical conductivity is also required, it is recommended that the upper limit of P 値 be controlled to 240, 200, 150, 100 ° in a preferred order. In addition, the above formula The lower limit of (6) is smaller than the lower limit 値 of the formula (2) specified in the first coating body. This is because the level of heat dissipation characteristics that can include the second coating body is slightly lower than that of the first coating body. The size of the body is increased, so the allowable range is expanded. Formula (7): 496 ^ X < 15% Assuming that the content of the black additive X is 3% or more, it is recommended to be 4% or more. Here, "X > 3%" is The premise is that in order to satisfy the above formula (6), the coefficient (X-3) on the left side of the formula must be positive (> 0). In addition, the lower limit of the above formula X, It is determined in order to obtain excellent heat dissipation characteristics while ensuring the characteristics of the coating body itself (paintability, appearance, etc.). The required characteristics cannot be obtained at 3% or less. The preferred lower limit is 5 in order. %, 7%, 8%, and 10%. On the other hand, the upper limit of X is not related to the heat dissipation characteristics. There is no particular limitation, but if it is 15% or more, the paintability will deteriorate, coating unevenness will occur, and the appearance will be poor. Therefore, the preferred upper limit considering the paintability is less than 15%, 13 % And 11%. Y > 1 U m The coating film thickness Y of the heat-dissipating coating film is based on the value of 0.5 // m or more, and 1 is recommended to be m or more. Here, the premise of "Y > 0.5 #m" is to satisfy The upper scale of this paper applies the Chinese national standard (CNS > A4 specification (210X297 mm) -39-1225826 A7 __ ^ _ B7___ 5. Description of the invention (37) Equation (6), the coefficient on the left side of the equation (γ — 〇 5) Must be positive (> 0). (Please read the precautions on the back before filling this page} The lower limit of the above formula Y is determined in order to obtain particularly excellent heat dissipation characteristics. When Y is below 0 · 5 // m, even if the black additive is added, it cannot be obtained. The required lower heat dissipation effect is in the order of 3 // m, 5 // m, 7 # m, 10 // m 〇 In addition, the upper limit of the above formula Y is not particularly limited in the relationship with the heat dissipation characteristics, but The purpose of the coating body of the present invention is to be used for electronic device components. Based on the relationship with this application, it is also required to improve the workability; especially if it is considered to prevent the coating film from cracking or peeling during bending processing, it is recommended to control it at 50 # m or less (in better order: 45 # m or less, 40 // m or less, 35 / zm or less, 30 // m or less). In order to have good processability and ensure excellent electrical conductivity, it is recommended to change the above Y Controlled below 1 2 // m (in a better order, 11 // m, preferably 10 // m). (Ii) Types of additives other than black additives. In order to improve the table For the heat dissipation characteristics of the coating film, when additives other than black additives are used, examples of these other additives include Ti02, ceramics, iron oxide, aluminum oxide, barium sulfate, and silicon oxide. These may be used in one kind. Or two or more. Black additives such as carbon black can also be added. In order to obtain the required heat dissipation characteristics, the film thickness of the heat-dissipating coating film can be determined according to the type of additives used, etc., and it is generally recommended to be 5 to 30. β m 〇 Specifically, when coating film containing TiCh, a large -40 can be added to the coating film-this paper size applies Chinese National Standard (CN'S) A4 specification (210X29 * 7 mm) 1225826 A7 ______ B7_ V. Description of the invention (38) (Please read the precautions on the back before filling out this page) 槪 50 ~ 70% titanium oxide, it is recommended to make the coating film thickness about 25 ~ 30 // m. Moreover, there is a metallic feeling in the implementation. It is recommended to add about 5 to 30% of A1 sheet, etc. to make the coating film thickness about 5 to 30 // m. Next, the "back coating film" of the second coating body of the present invention is added. Explanation. The above "surface coating film" is In order to ensure excellent self-cooling properties, a heat-dissipating coating film must be used. However, the "coating film on the back side" is only required to obtain the characteristics disclosed by the second coating body, and it is not necessarily a heat-dissipating coating film. The coated body does not include the "single-sided coated steel sheet" on which the coating film is not applied on the back surface of the substrate (the infrared emissivity of the original plate without the coating film is approximately 0.04, and the required self-cooling property cannot be obtained) However, as long as the above formula (4) is satisfied, any coating film can be used. Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, KK Industrial Cooperative Co., Ltd. ¾ Specifically, the black additive and other additives other than the black additive are used alone or in combination. The emissivity of the film can be adjusted by appropriately adjusting the amount of addition and the thickness of the coating film to form a coating film on the back surface. In addition, when a black coating is used to form the back coating film, the above-mentioned relationship between X and Y need not necessarily satisfy the above formula (6), even if the coating film has almost no heat dissipation (the P 値 is less than 0), as long as the surface is By properly controlling the infrared emissivity of the coating film, the required self-cooling properties can be ensured (see Nos. 1 and 11 of Table 6 described later). Alternatively, it is also possible to use a coating film in which the above additives are not added at all and the coating film thickness is controlled to a predetermined range (approximately 2.5 // m or more) (see Nos. 3 and 7 of Table 6 described later). This is because a certain degree of heat dissipation characteristics can be obtained only by the resin contained in the coating film. Specifically, for example, non-hydrophilicity is used as a coating film forming resin.

Also, this The coating body of the invention is coated with a coating film on the front and back surfaces of the substrate of any of the first coating body and the second coating body. If a conductive filler is added to both the front surface and the back surface, very good conductivity can be obtained. However, depending on the application, it is also possible to add a conductive filler on only one side, and even then, the predetermined conductivity can be determined.

Printed by Xiaogong Xiaohuang Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the above is a detailed description of the coating film that gives the coating body characteristics of the present invention. As mentioned above, the present invention is the most The important point is to make the coating film have a specific structure, and there is no particular limitation on substrates other than the coating film.

Any method is included in the scope of the present invention. Here, The structure of the coated body of the present invention obtained using a non-chromate-treated metal plate will be described. First, the substrate has been treated with a chromium-free underlayer, and it is necessary that the heat-dissipating coating film (at least the surface) contains a rust inhibitor. It is known that non-chromate treatment generally reduces the corrosion resistance, and in order to improve the corrosion resistance, the use of a rust inhibitor is indispensable. Here, the above-mentioned "underlayer treatment containing no chromium" is not particularly limited, and a commonly-used underlayer treatment can be generally performed.

By implementing a transparent coating, there is also an advantage that the defect will be eliminated. ---- ilk — (Please read the precautions on the back before filling out this page) Here, in order to maintain the required characteristics (heat dissipation characteristics / self-cooling), and improve the resistance to flaws and fingerprints, control the transparent coating film The thickness of the transparent coating film is very important. In addition to the heat dissipation property and excellent electrical conductivity, a more suitable range of the thickness of the transparent coating film may change.

When it is less than 0.1 m, the effect of improving the resistance to flaws and fingerprints cannot be obtained. Above 0.2 // m is more preferable, and above 0.3 // m is most preferable. However, even if the film thickness exceeds 1 0 // m, the effects of improving defect resistance and the like will saturate, only increasing the cost of the film, and the economy is not good. Therefore, the upper limit is preferably set to 10 // m. Below 8 // m is better, below 7 // m is better.

In addition, it is necessary to improve the resistance to defects and fingerprints. Therefore, it is recommended to control the film thickness of the transparent coating film to 0.1 to 3.0 // m. If it is less than 0.1 // m, the effect of improving the flaw resistance and fingerprint resistance cannot be obtained. Above 0.2 // m is better, above 0.3 // m is better. However, if the film thickness is too thick, the conductivity is adversely affected. Therefore, the upper limit is preferably 3.0 / zm. It is more preferably 2.0 // m or less, and most preferably 1.5 // m or less. As described above, the double-layer coating film structure is formed by covering the coating film with a transparent coating film. Compared with the single-layer coating film structure formed by the coating film alone, the paper standard can be significantly adapted to the Chinese National Standard (CNS) A4 standard.

Description of the invention (48) (Please read the precautions on the back before filling in this page) 'Drying method by hot air drying oven, etc. Considering the uniformity of coating film thickness, processing cost, and coating efficiency, a better roller coating method is used in practice. In addition, when a resin-coated metal plate is used as a substrate, in order to improve adhesion to a resin film or corrosion resistance, a phosphate treatment or a chromate treatment may be applied as a coating pretreatment. However, in the case of a chromate-treated material, it is preferable to control the amount of Cr deposited during the chromate treatment to 35 mg / m2 or less from the viewpoint of the dissolution of chromium in the use of the resin coating body. This is because if it is within the range, the elution of chromium from the base chromate treatment layer can be controlled. In addition, the conventional water-repellent coating of a surface coating provided with a chromate-treated material as required, tends to decrease in a humid environment with the dissolution of hexavalent chromium, but it is suppressed on the metal plate. As a result, the water-tightness of the coated film is not deteriorated. Alternatively, a non-chromate-type coating body can be obtained by performing the above-mentioned chromium-free undercoating treatment by a roll coating method, a spray coating method, a dipping treatment method, or the like.

I centimeter 7 9 2 X 1225826 A7 B7 V. Description of the invention (60) The following research can be made through Table 3. First, No. 1 ~ 2 is an example in which the average particle diameter of the black additive (carbon black) is not added without adding conductive filler (Ni). However, the average particle diameter is controlled within the preferred range of the present invention (5 ~ 100nm), therefore, good heat dissipation characteristics can be obtained. In addition, No. 3 to 11 are examples in which carbon black and Ni are contained in the coating film. Among these, No. 3 to 10 satisfy the elements of the present invention, and therefore, both heat dissipation characteristics and electrical conductivity are excellent. In addition, the conductivity of No. 10 is slightly lower than that of other examples (No. 3 to 9), which is considered to be due to the increase in the thickness of the coating film, which increases the resistance of the coating film. On the other hand, No.ll has a lower conductive thickness because the film thickness of the black coating film is outside the preferable upper limit (12 // m or less).

Nos. 12 to 22 are examples of covering a black coating film with a transparent film. Among them, the film thicknesses of the transparent coating films No. 12 to 18 and 21 to 22 are in a preferable range satisfying the present invention, and therefore, both the fingerprint resistance and the flaw resistance are excellent. However, since No. 12 ~ 14 does not contain conductive paste, or because the content of No. 21 conductive paste is below the lower limit of the present invention, it is the same as No. 15 ~ containing conductive paste. Compared with 21 and 23, the conductivity is reduced. In addition, No. 22 is an example in which a large amount of conductive filler is added. Although the conductivity is very good, it is confirmed that the processability is reduced (not shown in the table). On the other hand, since the film thickness of the transparent coating film of No. 19 exceeds the preferable upper limit of the present invention, the conductivity is affected. In addition, since the film thickness of No. 20 transparent film is outside the lower limit of the present invention, the fingerprint resistance and defect resistance are reduced.

Description of the invention (68) (Please read the precautions on the back before filling out this page) As can be seen from the above table, the coatings (No. 1 ~ 12) that meet the elements of the invention have maintained good heat dissipation characteristics. Moreover, it also has excellent self-cooling properties. In particular, in the formula (4) as an index of self-cooling property, Q 値 (= 0.9a-b) No. 1 to 8 which far exceeds 0.045 or more exhibits extremely excellent self-cooling property, and the larger Q 値, The better the self-cooling. In addition, coating bodies (No. 1 to 5, 7 to 9, 11 to 12) in which Ni is added to the coating film also have excellent electrical conductivity. Among them, No. 3 and 7 of Table 6 are examples in which the surface is covered with a coating film containing carbon black, and only the coating film (without additives) is coated on the back surface; No. 6 / Νο. 12 is coated on the surface / back surface and contains A coating film of carbon black is an example of a coating film containing titanium oxide on the back / surface; No. 10 is an example of a coating film having a metallic appearance on both the front and back surfaces; No.ll is a surface containing A1 The coating film of scales is an example in which a coating film containing carbon black is coated on the back surface. Since it satisfies the elements of the present invention, it has excellent self-cooling properties and excellent heat dissipation characteristics. Seals No. 1 and No. 11 in Table 6 are examples in which carbon black is added to the coating film on the back side. Although the above formula (6) is not satisfied, it satisfies the index specified by the second coating body. (4) and (5)], therefore, the self-cooling property and the heat dissipation characteristics are good. In contrast, No. 13 is a single-sided coated body that is not coated on one side, and has no basic heat dissipation characteristics. Similarly, in No. 14, the composition of the surface (the coating film containing carbon black) does not satisfy the above formula (6). Therefore, the formula (5), which is an index of heat dissipation characteristics, does not satisfy the required heat dissipation characteristics. No. 15 does not add additives on the back of the table, and the thickness of the coating film is thin. Therefore, the paper size is applicable to the Chinese National Standard (CNS) A4 (210X297 mm) Γ'Ί _ 1225826 A7 ____B7 V. Description of the invention (69) 'Not getting the required thermal characteristics. (Please read the precautions on the back before filling in this page.) On the other hand, No. 16 is an example of the same emissivity on the back of the table, which does not give the required self-cooling property. No. 17 is a conventional example in which the back surface of the table is blackened by the same method. The emissivity of the back surface of the table is the same. Therefore, the required self-cooling property was not obtained. No. 18 is an example in which the back surface has a higher emissivity than the front surface, and the self-cooling property is reduced. In Example 6 below, the chromium-free coated body of the present invention was investigated mainly on corrosion resistance, coating film adhesion, processability, and electrical conductivity. Example 6: Evaluation of the corrosion resistance, coating film adhesion, processability, and electrical conductivity of a chromium-free coating body In this example, the front and back surfaces of a substrate subjected to a primer treatment containing no chromium were applied. The above-mentioned various characteristics were evaluated with the same amount of paint using a coated body to which a heat-radiating coating film of the same thickness was applied. Specifically, Yinzi of Xiaogong Consumer Cooperative, Bureau of Wisdom and Wealth of the Ministry of Economic Affairs, uses an electric ore zinc steel plate (plate thickness 0.8mm, and the amount of Zn attached on one side is 20g / m2) as the original plate. SarfcoatEC2000 (Si adhesion 50mg / m2) "chromium-free primer treatment. On the front and back surfaces, apply the same amount as a primer coating: carbon black (10%), and the coating components described in Table 8 [base.

Among them, the film thickness of the heat dissipation coating film was all 8 μm, and the film thickness of the transparent coating film was 1 μm. In addition, No. 21 is an example in which Ni is not added as a conductive material. For each of the test materials thus obtained, the same method as in Example 1 was used to evaluate heat dissipation and electrical conductivity, and the same method as in Example 3 was used to evaluate fingerprint resistance and defect resistance. The corrosion resistance, coating film adhesion, and processability were evaluated in accordance with the following criteria. [Corrosion resistance] Using each of the above test materials, the salt water spray test specified in JIS-Z-237 1 was performed for 72 hours or 120 hours, and the appearance abnormalities (rust, Expansion).

Description of Invention (73) (Please read the notes on the back before filling this page) According to the above table, you can investigate as follows. In addition, each of the above test materials has good heat dissipation properties, and it was confirmed that No. 1 to 22 with a transparent coating film had excellent fingerprint resistance and defect resistance (not shown in the table). First, the coated bodies (Nos. 2 to 5, 7 to 14, 16 to 17, 21 to 23) satisfying the elements of the present invention are excellent in corrosion resistance, coating film adhesion, and workability. Particularly, in the above-mentioned coating body, the coating body in which the melamine-based crosslinking agent and the isocyanate-based crosslinking agent are combined in a predetermined ratio has the above-mentioned characteristics compared with the coating body (No. 8, 9) used alone. very talented. In addition, the coated body (the above-mentioned coated body other than No. 23) provided with a transparent coating film on the heat-dissipating coating film has very good corrosion resistance. In addition, No. 8 is an example in which a melamine-based cross-linking agent (addition amount of 5.5% by mass) is used alone as a cross-linking agent, and a transparent coating film is applied. Very good corrosion resistance of the same degree [area ratio of appearance abnormal part of salt spray test corrosion resistance test (120 hours) is less than 1%] (not shown in the table). In addition, the coating body (the above-mentioned coating body other than No. 21) to which the conductive filler Ni was added also had good conductivity. Printed by Xiaogong Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In contrast, painted bodies (No. 1, 6, 15, 18-20) that do not satisfy the elements of the present invention have the following disadvantages. First, No. 1 is an example in which a rust inhibitor is not used, and its corrosion resistance is poor.

No. 6 is an example in which the amount of resin is small, and the coating film adhesion and processability are reduced.
