Description

313630 A7 ___B7 _ V. Description of the invention (1) The present invention in a broad sense relates to a technique for forming the surface of a substrate and maintaining a high degree of hydrophilicity. More specifically, the present invention relates to an anti-fog technique for forming highly hydrophilic surfaces of mirrors, lenses, plate glass, and other transparent substrates to prevent the substrate from fogging or forming water droplets. In addition, the present invention relates to a technique for making the surface of buildings, doors, windows, glass windows, mechanical devices, or articles highly hydrophilic. To prevent surface contamination or self-purification or easy surface cleaning. Background Art. When it is cold, windshield glass or door and window glass of automobiles or other vehicles, door and window glass of buildings, lenses of glasses, and glass cover sheets of various instrument plates often fog due to condensation of moisture. Moreover, we often encounter fogging in the bathroom or on the wash table mirror or glasses lens due to heat. The fogging on the surface of the article is caused by the condensation of moisture in the atmosphere when the surface is in a temperature atmosphere below the dew point, causing the surface to fog up. When the condensed water droplets are thin enough and their diameter is 1 '/ 2 of the wavelength of visible light, the water droplets cause light scattering, forming opaqueness on the glass or lens surface, and losing visibility. Oxygen printed by the Beigong Consumer Cooperative of the Ministry of Economic Affairs of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) When moisture condenses, the small condensed water droplets merge into each other to form larger discrete water droplets. The interface and the interface between water droplets and air darken, blur, streak or fog the surface due to light refraction. As a result, the see-through image of glass transparent objects is distorted, and the reflected image of the mirror is disturbed. When the windshield or window glass of the vehicle, the window glass of the building, the rearview mirror of the vehicle, the lens of the glasses, the protective cover of the mask or the helmet are caused by rain, most of the discrete water droplets adhere to the surface, and the above surface becomes dark and blurred This paper uses the Chinese National Standard (CNS) A4 specification (210X297mm).

Description of the invention (2), streaks or fogging, loss of visibility. The term “anti-fog” as used in this specification and the scope of patent application broadly refers to a technique for preventing fogging or picking up condensed water droplets or optical obstacles caused by the attached water droplets as described above. Of course, anti-fog technology has a great influence on safety or the efficiency of various operations. For example, the windshield or door and window glass of the vehicle or the rearview mirror fogs up, which hinders the safety of the vehicle. The fogging of endoscope chains or dental mirrors for dentistry hinders accurate diagnosis and causes surgical obstacles. The cover glass of the instrument plate is difficult to read. In order to ensure the sight in cold or rainy days, windshields for automobiles and other vehicles are generally equipped with wipers or anti-fog devices or heaters. However, these devices cannot be installed on the side door and window glass of the car or the rear mirror outside the car. These anti-fog devices are also not easy to install on the door and window glass or spectacle lenses of buildings, endoscope lenses or dental mirrors, protective glasses, protective covers for masks or safety helmets, and glass coverslips for instrument plates. As is well known, the simple + single anti-fog method used in the past is to apply an anti-fog composition with a hydrophilic compound such as ethylene glycol or a water-repellent compound of silicone to the surface. However, these anti-fog coatings are only effective for a while, and can be easily removed by water washing or contact ό: 'Shikaiping 3 — 1 2 9 3 5 7 (Mitsubishi Yayon) reveals that a polymer layer is provided on the surface of the substrate, and this layer is irradiated After ultraviolet ray treatment with alkali aqueous solution into high-density acidic groups, by this treatment to make the surface of the polymer layer a hydrophilic mirror anti-fog method. However, this method also gradually loses the anti-fog property due to the contaminants attached to the surface after a period of time, the surface loses its hydrophilicity.

Description of the invention (4) Dust or particles floating in the atmosphere will pile up on the roof or outer wall of the building when it is sunny . The accumulation will flow to the outer wall of the building with rainwater. On a rainy day λ, floating dust will be carried by rainwater to the exterior wall of the building or the surface of the building outside the house. As a result, pollutants adhere to the surface along with rainwater. Stripes of dirt appear on the surface when the surface is dry. 1 The dirt of building exterior materials or coatings is composed of pollutants such as combustion products of carbon black, urban dust, and inorganic substances of clay particles. This kind of pollutant has diversity, and the anti-pollution measures are complicated (Okayoshi Takamoto, outer wall, pollution promotion test of materials. Law ", The Architectural Society of Japan, Department of Structural Papers, No. 404, October 1989, Ρ. 15-24) 0 In the past, it was generally considered that the use of hydrophobic coatings of polytetrafluoroethylene (PTF Ε) to prevent pollution of building exterior walls, etc., but recently it is considered that the urban dust that contains many lipophilic components should be exhausted. May make the surface of the coating film ideal for forming hydrophilicity (Polymer, Volume 44, May 1959, Ρ. 3 0 7) ° Therefore, it is proposed to coat the building with a hydrophilic graft polymer (Xinmin Mdxue Industry Daily News, "January 30, 1959"). According to the report, the contact angle of the coating film with water is 30 ~ 40. And is hydrophilic. However, the contact angle of inorganic dust and water of a typical clay mineral is 20 to 50. , The contact angle with water is 30 ~ 40. The graft polymer has affinity and is easy to adhere to the surface, so the coating film of the graft polymer cannot prevent contamination by inorganic dust. In the past, all kinds of hydrophilic coatings on the market were made of acrylic resin and acrylic.

The surface of the invention (6) is highly hydrophilic. It was surprisingly found that the photocatalytic titanium dioxide was photoexcited with ultraviolet light, and the surface formed a highly hydrophilic contact angle of 10 with water. The following is more detailed below, especially close to Q. . The present invention is based on this new discoverer. In a broad sense, the present invention provides a method for making a surface of a substrate highly hydrophilic, a substrate having a highly hydrophilic surface, and a method of manufacturing the same. According to the present invention, the surface of the base material is covered with an abrasion-resistant photocatalytic coating composed of a photocatalyst semiconductor material. When light of a wavelength with a higher energy than the bandgap energy of the photocatalyst semiconductor is irradiated with sufficient illuminance for a sufficient time, the surface of the photocatalyst coating becomes superhydrophilic. '' Superhydrophilicity (superhydrophilicity) '' or 'superhydrophilicity (superliydropliilic)' refers to the high hydrophilicity (that is, water wettability) below 10 °, which is converted into the contact angle with water, ideally below 5 ° . Similarly, ~ superhydrop-hilification 〃 or 'form superhydropilify (superhydropilify) " refers to the surface formation converted into a contact angle with water of about 10 ° or less, ideally a height of about 5 ° or less Hydrophilic '. The phenomenon of surface hydrophilization formed by the light excitation of the photocatalyst cannot be explained in detail at present. The formation of superhydrophilization with photocatalysts in the photocatalyst field is not necessarily the same as the photolysis of substances produced by the redox reaction of photocatalysts known in the past. Regarding this point, in the past, the photocatalyst redox reaction was thought to use photoexcitation to generate electrons-positive pore pairs. The generated electrons reduce the surface oxygen to generate peroxide ions (0,), while the positive pores oxidize the surface hydroxyl groups. Free hydroxyl group (· ΟΗ), these highly reactive active oxygen species (〇2 — or ΟΗ) by redox reaction to decompose the substance (please read the precautions on the back before filling this page) Κ ^ -— — ϋ-n -This paper scale applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 3 ^ 3630 Α7 Β7 Printed by the Beigong Consumer Cooperative of the Central Ministry of Economic Affairs of the Ministry of Economic Affairs 5. Description of the invention (7) 0 However, the photocatalyst is used to form super hydrophilic The phenomenon has at least two points that are different from those of the past. Excessive light-excited electrons are formed on the conductor, and the electron-positive pore pairs generated by the light excitation do not participate in the redox reaction and recombine. However, the use of photocatalysts to form super-hydrophilization phenomena will be described later, and even photocatalysts such as rutile or thorium oxide will react. The second point is that the photocatalytic oxidation-reduction reaction used to decompose substances, and the thickness of the photocatalyst layer is at least 100 μm or more. On the other hand, the photocatalyst super-hydrophilization will produce a reaction even if the film thickness of the photocatalyst coating is n m. Therefore, although it is not a clear conclusion, the phenomenon of using photocatalyst to form superhydrophilicity and photocatalytic oxidation-reduction reaction to photodecompose a substance is slightly different. However, as will be described later, if light with a higher energy than the bandgap energy of the photocatalyst is not irradiated, superhydrophilicity of the surface cannot be generated. Probably the photocatalyst action of the photocatalyst causes water to be chemically adsorbed on the surface of the photocatalyst coating in the form of hydroxyl groups (ΟΗ—), making the surface superhydrophilic. After light excitation is used to make the surface of the photocatalytic coating highly hydrophilic, the hydrophilicity of the surface of the substrate can be maintained for a period of time even if the substrate is placed in a dark place. Over time, the surface hydroxyl groups will adsorb pollutants. When the surface gradually loses its superhydrophilicity, it can be restored by light excitation. Initially, in order to make the photocatalyst coating superhydrophilic, any light source having a higher energy wavelength than the band gap energy of the photocatalyst can be used.

Description of the invention (8) Titanium oxide, which stimulates the photocatalyst poems grown in the field of ultraviolet light, and the substrate covered with the photocatalytic coating can shine the sun, and the sun can be used UV light. As will be described later, when the% touch coating is titanium dioxide containing silicon dioxide, it can easily form hydrophilization even with the weak ultraviolet rays in fluorescent lamps. After the surface of the photocatalyst coating is superhydrophilized, it can maintain superhydrophilicity or restore hydrophilicity with weak light. For example, to maintain or restore the super-hydrophilicity of titanium dioxide, even the faint ultraviolet rays of indoor lighting such as fluorescent lamps are sufficient. Even if the photocatalyst coating is made very thin, it still has super-hydrophilicity, especially the photocatalyst semiconductor material composed of metal oxide has sufficient hardness. Therefore, the photocatalyst coating has sufficient durability and wear resistance. The superhydrophilization of the surface can be applied to various applications. The present invention provides an anti-fog method for a transparent member, and a method for manufacturing the anti-fog transparent member. According to the present invention, a transparent member covered with a photocatalytic coating is first prepared, or the surface of the transparent member is covered with a photocatalytic coating. Transparent components include rear-view mirrors for cars, bathroom or lavatory mirrors, dental mirrors and road mirrors; spectacle lenses, optical lenses, camera lenses, interior lenses, lighting lenses, and other lenses; San Yan; Door and window glass of buildings or surveillance towers; cars, trains, airplanes, boats, submarines, snowmobiles, cable cars, playground cages, spaceship glass windows; cars, trains, airplanes, ships, submarines, snowmobiles , Windshields for earth motorcycles, motorcycles, cable cars, playground cages, spaceships, etc .; protective armor or masks (including diving goggles) used for protection or sports; protective helmets Cover (please read the notes on the back before filling this page)

Description of the invention (9): The glass of the frozen food display box; the cover glass of the instrument. Light shines on a transparent member with a photocatalytic coating, which causes photocatalyst * to generate light excitation, thereby making the surface of the catalytic coating superhydrophilic and neutralized, even if moisture or moisture in the air is condensed Condensed water also does not contain individual water droplets, but forms the same water film, so the surface does not produce light scattering "fogging" (hazy) phenomenon. Similarly, the door and window glass or car rear mirror or car windshield or spectacle lens or protective cover of the helmet will cause the water droplets attached to the surface to rapidly expand into the same water film after rain or water spray, so it is not It will form scattered water droplets that will hinder your vision. Therefore, it can ensure a high degree of visibility and visibility, ensure the safety of real vehicles or transportation, and improve the efficiency of various operations and activities. In addition, the present invention provides a method for self-purifying a substrate surface by making the surface of the substrate super-hydrophilic and self-purifying by rainwater, and a method for manufacturing the same. Substrates include, for example, metals, ceramics, glass, plastics, wood, stone, cement, concrete, combinations of these, laminates of these, or exteriors of buildings formed from other materials, window frames, structural members, door and window glass; Exterior and painting of cars, trains, airplanes, ships, etc .; exterior of machinery or articles, dust covers and painting; traffic signs, various display devices, exterior of advertising towers and painting. The surface of the substrate is covered with a photocatalytic coating. Mechanical devices or articles placed outside buildings or houses are exposed to sunlight during the day, so the surface of the photocatalyst coating is highly hydrophilic. Sometimes it rains. When the super-hydrophilized surface is exposed to rain, the dust on the surface of the substrate is suitable for the standard of China National Standard (CNS) A4 (210 to 297 mm) -12-(please Read the precautions on the back and then fill out this page).

Description of Invention (10) When Angstrom or pollutants are washed by raindrops, the surface is purified by itself. The photocatalyst coating surface has a contact angle of 10 with water. The following "ideally 5 ° or less" is about Q. The following high degree of hydrophilization makes it easy to remove inorganic dust such as clay minerals from the surface not only for urban dust containing many lipophilic components. Therefore, the surface of the substrate is highly self-purifying and clean by natural action. For example, super high-rise buildings do not require glass wiping operations or drastically reduce wiping operations. In other aspects of the present invention, the present invention provides a method for preventing the surface from being contaminated. It is provided with a photocatalytic coating on the surface of a building or glass window or a mechanical device or article to make the surface highly hydrophilic. When rainwater containing pollutants floating in the atmosphere flows to the superhydrophilized surface, the surface will prevent the pollutants from adhering. Therefore, after the aforementioned self-purification by rainwater, the surfaces of buildings and the like are kept almost permanently clean. ^ In other aspects of the invention, metal, ceramics, glass, plastic, wood, stone, cement, concrete, combinations of these, or devices or articles formed from these laminates (such as the exterior of buildings, Building interior materials, door and window glass, residential equipment, sanitary equipment, bathtubs, washstands, lighting appliances, kitchen supplies, tableware, countertops, tableware, kitchen utensils, ventilation fans) are photocatalytic The coating is covered and can be photo-excited if necessary. When the articles contaminated with grease are immersed in water and moistened with water or washed with water, the oil stains will be detached from the surface of the photocatalyst coating treated with super-hydrophilization, and the oil stains can be easily removed.

In other aspects of the present invention, the present invention is a method of preventing the growth of water droplets adhering to a substrate or spreading the water droplets adhering to the same water film. Therefore, the surface of the substrate is covered with a photocatalytic coating. When the photocatalyst coating is photoexcited to make its surface superhydrophilic, the moisture attached to the surface of the substrate condenses or the water extract spreads on the surface to form a water film. When this method is applied to a heat sink of a heat exchanger, for example, it can prevent condensation water from blocking the passage of the heat exchange medium and improve the heat exchange rate.

Description of the invention (13) Photocatalyst The most ideal photocatalyst used in the photocatalyst fe of this invention is titanium dioxide (Ti〇2). Titanium dioxide has no #, is chemically stable, and is cheap and easy to obtain. Titanium dioxide has a high band gap energy. Therefore, ultraviolet light is required for light excitation. The process of light excitation does not absorb visible light, so it does not produce color due to complementary color components. Therefore, it is particularly suitable for coating on transparent members such as glass, lenses, and lenses. Can use Rutile or Anatase type dioxide: The advantages of Rutile titanium dioxide. It is easy to obtain a sol dispersed in the market into very fine particles, and it is easy to form a very thin film. The advantage of Anatase type titanium dioxide is that it can be sintered at high temperature, and a film with excellent strength and wear resistance can be obtained. As shown in Figure 1, iU a t a s e-type titanium dioxide has a lower transmission band level than R u t i 1 e-type, but it can be used for super-hydrophilization using photocatalysts. As shown in FIG. 2A, the photocatalytic coating layer 12 made of titanium dioxide 'titanium covers the substrate 10, and when ultraviolet light is used to photoexcite the titanium dioxide, the water is treated in the form of hydroxyl groups (ΟΗ—) by the photocatalyst Chemisorption on the surface, as a result the surface becomes super hydrophilic.

Description of the invention (14) As shown in Figure 2B, the photocatalytic coating can be formed by disposing the photocatalyst particles 14 in the metal oxide layer 16 . In particular, as will be described later, when silicon dioxide or thorium oxide is mixed with β-phototrophic medium, the surface can be highly hydrophilized. Film thickness of the photocatalytic coating When the substrate, such as glass, lens or mirror, is composed of a transparent material, the ideal film thickness of the photocatalytic coating is 0.2 or less. This prevents the photocatalytic coating from being colored by dry light picking. The thinner the photocatalytic coating can ensure the transparency of the substrate. Moreover, the thinner the film thickness, the higher the abrasion resistance of the photocatalytic coating. On the surface of the photocatalyst coating, a protective layer or other functional film that can be hydrophilized with abrasion resistance or corrosion resistance can also be provided. The photocatalyst layer formed by firing amorphous titanium dioxide is formed using a heat-resistant material such as ceramics or glass, in order to form a super-hydrophilic photocatalytic coating with zero contact angle with water and excellent abrasion resistance One of the ideal methods is to first cover the surface of the substrate with amorphous titanium dioxide, and then transform the amorphous titanium dioxide into crystalline oxynitride (Anatase or Rutile) by firing.

Then these Yu drive bodies are hydrolyzed and dehydrated to form a mixture of amorphous titanium dioxide and amorphous silicon dioxide The thin film formed. The second heating is above the crystallization temperature of titanium dioxide and below the softening point of the base material, which transforms the amorphous titanium dioxide into crystalline titanium dioxide. The photocatalyst layer composed of titanium dioxide containing tin oxide is A more ideal method for forming a super-hydrophilic photocatalyst coating with a contact angle of 0 ° with water and excellent wear resistance is to form a photocatalytic coating composed of a mixture of titanium dioxide and thorium oxide on the surface of the substrate For the sum of titanium dioxide and thorium oxide, use 1 to 95% by weight, ideally 1 to 50% by weight of thorium oxide. In order to form titanium dioxide containing thorium oxide Any one of the following methods can be used for the photocatalytic coating: (1) A suspension containing anatase or rutile titanium dioxide particles and thorium oxide particles is applied to the surface of the substrate and sintered at a temperature below the softening point of the substrate.

Description of the invention (19) The titanium compound is hydrolyzed and dehydrated and condensed to form a thin film of amorphous titanium dioxide dispersed with tin oxide particles. Then heated to titanium dioxide Crystallization * 4 Above the melting temperature, the temperature of the substrate I: below the melting point, the amorphous titanium dioxide is transformed into crystalline titanium dioxide. The photocatalyst-containing siloxane coating is designed to form a super affinity with a water contact angle of 0 ° The other ideal method of photocatalytic coating is to disperse the photocatalyst particles in the coating film forming elements of uncured or partially hardened siloxane (organopolysiloxane) or siloxane precursor. The paint composition is applied to the surface of the substrate to form a coating film. After the element is hardened and the photocatalyst is photoexcited, as described in Examples 1 3 and 1 4 described later , The organic group bonded to the silicon atom of the siloxane molecule is replaced by a hydroxyl group by the photocatalyst action of the photocatalyst, and the surface of the photocatalyst coating becomes superhydrophilic. (Read the precautions on the back before filling out this page) This approach has several advantages. Siloxane coatings containing photocatalysts can be hardened at room temperature or lower temperatures, so they can be applied to substrates formed from non-heat-resistant materials such as plastics. This photocatalyst-containing coating composition can be applied to a substrate requiring super-hydrophilization at any time, if necessary, by spraying, roller coating, or the like. The use of sunlight can also stimulate the photocatalyst to form super-hydrophilic. When a coating film is formed on a plastically processed substrate such as a steel plate, after hardening the coating film and before light excitation, the steel plate is easily plastic-processed if necessary. Before light excitation, the organic group is bonded to the silicon atom of the siloxane molecule. Therefore, the paper size of the coated film is applicable to the Chinese National Standard (CNS) A4 specification (.210X297 mm). Printed by the consumer cooperative A7 B7__ 5. Description of the invention (20) It has sufficient flexibility, so it is easy to plastically process the steel plate without damaging the coating film. After plastic processing, when the photocatalyst is photoexcited, the organic gene photocatalyst, which is bonded to the silogen of the siloxane molecule, is replaced by a hydroxyl group to make the surface of the coating film superhydrophilic. Siloxane coatings containing photocatalysts have a siloxane bond, so they are fully resistant to the photooxidation of photocatalysts. The photocatalytic coating composed of a photocatalyst-containing siloxane coating • Other advantages are that when the surface is superhydrophilized, it can maintain long-term superhydrophilicity even when stored in a dark place, and even if it is a fluorescent lamp The light from the 'indoor lighting' lamp can also restore super-hydrophilicity.

In general, when light excitation is generated with an ultraviolet illuminance of 0.001 nW / cm2, superhydrophilicity occurs within a few days, and the contact angle with water is about 0. . The ultraviolet illuminance contained in the sunlight reaching the surface is about 0.1 ~ lmW / cm2. Therefore, it can make the surface superhydrophilic in a shorter time when placed under sunlight. The surface of the substrate can be cleaned by rain water, or to prevent the attachment of pollutants, a photocatalyst coating can be formed with a catalyst that can be excited by ultraviolet light or visible light. Articles covered with a photocatalytic coating can be placed outside the house exposed to the sun or rain.

The proportions of titanium dioxide in the top coat are 50% by weight, 60% by weight, and 90% by weight. 'Λ. In accordance with Japanese Industrial Regulation 1 (J I S) Η 8 6 0 2, use the pencil core to scratch the surface of the sample to detect the hardest pencil core that peeled off the topcoat. The same test was carried out for the sample coated with the base coat only. The results are shown in Figure 8. Although the surface coating of titanium dioxide with a weight ratio of 90% by weight is peeled off with a pencil core with a hardness of 5 Β, the weight of titanium dioxide is reduced to 60%. , Showing sufficient abrasion resistance. Obviously, the abrasion resistance of the top coat increases as the content of titanium dioxide decreases. Example 17 The effect of film thickness is the same as that of Example 13; firstly, a primer layer of polysiloxane with a film thickness of 5 vm is formed on the surface of a 10 cm square silver plate, and then a film containing different film thicknesses is formed thereon.

This paper scale is printed in Chinese National Standard (CNS) A4 (210X297mm) -47-A7 B7 printed by the Central Standards Bureau of the Ministry of Economic Affairs. The invention description (45). The results are shown in Figure 9 ·. It is known from Fig. 9 that each sample is not limited to the film thickness, and is irradiated for 50 hours to form a highly hydrophilic ft on the inner surface, and the contact angle with water is less than 3 °. It is particularly attractive that the objective is to obtain a photocatalyst activity sufficient for the surface of the top coat to be highly hydrated even if the film thickness of the top coat containing titanium dioxide is 0.2 or less. Generally, when the film thickness of the transparent layer exceeds 0.2 " m or more, color will be generated due to light interference. This embodiment shows that when the film thickness of the top coat is 0.2 or less, the top coat can be prevented from being colored due to light interference, and the surface can also be made highly hydrophilic. Next, the photodegradation performance of the methyl mercaptan in sample 1 to sample # 5 was measured. Place these samples in a UV-permeable quartz glass Rongzhen 1 1. In a desiccator, inject nitrogen gas containing methyl mercaptan so that the concentration of methyl mercaptan is 3 p pm. In the desiccator, a 4 W BLB fluorescent lamp was placed at a distance of 8 cm from the sample, and ultraviolet light was irradiated with an ultraviolet illuminance of 0.3 m W / cm 2. After 30 minutes, the gas in the dryer was taken, and the methyl mercaptan concentration was measured by gas chromatography, and the removal rate of methyl mercaptan was measured. The results are shown in Figure 10. Figure 10 shows that as the film thickness of the photocatalyst layer increases, the photodegradation performance of methyl mercaptan also increases. As shown in Figure 9, the superhydrophilization phenomenon of the photocatalyst is not affected by the film, and the photodegradation performance of the photocatalyst is obviously affected by the film thickness. Therefore, the phenomenon of superhydrophilization by photocatalyst in the field of photocatalyst is not necessarily the same as the conventional photocatalytic redox reaction.

A sample covered by a film made of titanium dioxide and silicon dioxide. . The contact angle of each sample immediately after firing with water is shown in Figure 12. It is known from Figure i 2 that the initial contact angle will decrease when silicon dioxide is added. After being placed in a dark place for 8 days, the contact angle with water is shown in Figure 13. Comparing Figure 12 and Figure 13, it can be seen that samples with a silica molar fraction of more than 10% will not lose their dehydrophilicity when placed in a dark place. Then, the surface of the sample was irradiated with ultraviolet light with a UV illuminance of 〇'3 m W / cm 2 using a BLB fluorescent lamp for 2 days. The contact angle with water after irradiation is shown in Figure 14. When silicon dioxide is added to titanium dioxide, it is easy to quickly restore the hydrophilicity by ultraviolet irradiation. Then place the sample in a dark place for 8 days and measure the contact angle with water. The results are shown in Figure 15. When silicon dioxide is added to titanium dioxide, it will rarely lose its hydrophilicity even if it is placed in a dark place after being irradiated with ultraviolet rays. The abrasion resistance of the sintered film of titanium dioxide and silicon dioxide was measured using a pencil scratch test. The results are shown in Figure 16.

， TT Ministry of Economic Affairs, Central Bureau of Standardization, Beigong Consumer Cooperation Co., Ltd. Du Printed In order to make it easier to understand, the contact angle and color difference of Table 9_ and Table 10 with water are plotted on Figure 17. In Fig. 17 of Fig. 17, curve A represents the relationship between the color difference caused by combustion products such as carbon black in the atmosphere and dirt such as urban dust and the contact angle with water in the pollution acceleration test, and curve B represents In the sludge test, the relationship between the color difference of the sludge and the contact angle with water. Referring to Fig. 17 from curve A, it is known that as the contact angle between the base material and water increases, pollution using combustion products or urban dust becomes more obvious. This is because the pollutants of combustion products or urban dust are basically hydrophobic, and the paper size is quickly adopted by China National Standards (CNS) A4 (210X297 mm) _Qiu-Ministry of Economic Affairs Printed by the cooperative 313630-V. Description of the invention (64) &amp; Easy to attach to hydrophobic surfaces. The contact angle of sludge and scale of curve B with water is 20. ~ 50. There is a peak value within the range. This is because the inorganic substances of mud and soil have a contact angle of 20 with water. The hydrophilicity of ~ 50 ° makes it easy to attach to a surface that is similar to hydrophilicity. Therefore, the surface is formed to be in contact with water. The contact angle is less than 20 °, or the contact angle with water is 60. The above @hydrophobicity can prevent inorganic substances from adhering to the surface. When the contact angle with water is less than 20 °, the pollution of sludge can be reduced. Because the surface forms a highly hydrophilic contact angle with water of less than 20 °, the hydrophilicity to water is greater than the affinity to inorganic substances. And the use of preferentially attached to the surface of the water to hinder the attachment of inorganic substances, at the same time, attached or to be attached. Inorganic substances are easily washed away by water. From the above, it is known that in order to prevent hydrophobic dirt and hydrophilic dirt from adhering to the surface of buildings and the like, or to wash away the dirt accumulated on the surface by rain to form a self-cleaning surface, as long as the surface is in contact with water The angle is below 20 °, ideally 10.

Description of the invention (67) It is known from Table 1 1 that it is covered only with titanium dioxide # 8 sample and well 9 sample, the contact with water is greater than 10 °. This is due to the fact that the alkaline ion of the network is dissipated into titanium dioxide because of the sodium ions in the firing. The photocatalyst activity of An at as e is hindered. On the other hand, the surface of samples # 1 to # 6 in combination with S i 〇2 is highly hydrophilic. According to sample # 7, tin oxide and dioxide are the same as semiconductor photocatalyst, which has the effect of making the surface hydrophilic.
