Disclosure of Invention
It has been known from the past that zinc cyanurate can impart a high corrosion-preventing function to a metal surface. However, zinc cyanurate obtained by the above-described production method has a needle-like or plate-like particle shape and a relatively large particle diameter, and when dispersed in a medium, it becomes a non-uniform slurry, and thus has a problem of difficulty in handling the composition for coating formed by mixing with a resin as a binder.
The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a coating composition capable of forming a coating film having high adhesion to a substrate, and to provide a coating composition capable of sufficiently exerting functions such as corrosion resistance of a metal surface and the like possessed by zinc cyanurate, and capable of exerting effects such as improvement in durability, scratch resistance, corrosion resistance of a substrate, and prevention of change in color tone of a substrate (occurrence of appearance failure is less likely to occur) on a PET substrate, wood and the like.
As a result of intensive studies to solve the above problems, the present inventors have found that a coating composition having excellent dispersibility and capable of maintaining a stable dispersion state can be surprisingly obtained by using a dispersion obtained by dispersing both inorganic oxide particles and zinc cyanurate particles as a dispersoid in a liquid medium as a coating additive and compounding the coating additive with a resin component such as a resin emulsion. Further, it has been found that the above-mentioned coating composition can provide a coating film which is excellent in adhesion to a substrate (coated surface), has little cure shrinkage, and is excellent in follow-up property against deformation of the substrate, and thus, in addition to the anticorrosive effect on a metal surface, various functions of the coating composition can be expected: the present invention has been completed by improving the durability, scratch resistance, and corrosion resistance of a substrate, and preventing the effects of color change of the substrate.

Among them, basic salts are preferably used in the present invention, and Zn 3(C3N3O3)2·2ZnO·3H2 O can be used, for example.
In the present invention, it is preferable to use zinc cyanurate particles having a needle-like or plate-like elongated particle shape, wherein the length of the major axis of the primary particles is 400nm to 3,000nm and the length of the minor axis of the primary particles is 10nm to 300nm, and the length ratio (major axis/minor axis) of the major axis to the minor axis is 1.3 to 300, when measured by observation with a transmission electron microscope. As the zinc cyanurate particles, particles having a specific surface area of, for example, 10m 2/g~100m2/g can be used.
For example, zinc cyanurate particles having a major axis length of 400nm to 1,000nm, or 400nm to 800nm, or 400nm to 600nm of primary particles, a minor axis length of 10nm to 300nm, or 10nm to 90nm, or 30nm to 90nm of primary particles, and a length ratio (major axis/minor axis) of the major axis to the minor axis of 1.3 to 100 at this time can be preferably used. Further, the length ratio of the major axis to the minor axis may be any combination selected from 1.3 or 4.4 of the lower limit value and 12, 20, 80 or 100 of the upper limit value.
For example, zinc cyanurate particles having a major axis length of primary particles of 1,000nm to 3,000nm, or 2,000nm to 3,000nm, a minor axis length of primary particles of 80 nm to 300nm, or 100nm to 300nm, and a length ratio (major axis/minor axis) of the major axis to the minor axis of 3.3 to 37.5 can be preferably used. Further, the length ratio of the major axis to the minor axis may be any combination selected from 3.3 of the lower limit value, 20 of the upper limit value, and 37.5.
The zinc cyanurate particles may be dispersed in pure water, and the average particle diameter of the zinc cyanurate particles in the aqueous dispersion may be measured by using a laser diffraction particle size distribution measuring apparatus (for example, trade name SALD-7500nano, manufactured by shimadzu corporation).
The zinc cyanurate particles in the aqueous dispersion have an average particle diameter of 80nm to 20,000nm, as measured by a laser diffraction method.
As a method for producing zinc cyanurate particles, there are 2 production methods, namely, a method for producing a slurry in which a raw material is dispersed in water and a method for producing a solid phase in which a raw material is in a powder state.
The method for producing a slurry in which raw materials are subjected to a liquid phase reaction in a water-dispersed state is, for example, the following method: zinc oxide or basic zinc carbonate, cyanuric acid and water are prepared at a concentration of 0.1 to 10.0 mass% of cyanuric acid concentration, and the mixed slurry is wet-dispersed at a temperature of 5 to 55 ℃ using a liquid disperser, whereby a reaction and dispersion of the product are carried out to obtain a slurry (dispersion) of zinc cyanurate particles.
Further, cyanuric acid dissolved in water reacts rapidly with zinc oxide and basic zinc carbonate to promote particle growth, so zinc cyanurate particles as a product tend to become large. Therefore, the reaction is preferably carried out at 55℃or less or 45℃or less.
The wet dispersion is performed using a dispersion medium. By performing wet dispersion using a dispersion medium, mechanical energy generated by collision of the dispersion medium can cause mechanochemical reaction of cyanuric acid with at least one selected from zinc oxide and basic zinc carbonate. The mechanochemical reaction is a chemical reaction in which zinc oxide, basic zinc carbonate, and cyanuric acid are chemically reacted by applying mechanical energy thereto from various aspects by collision of a dispersion medium.
Examples of the dispersion medium include stabilized zirconia beads, silica glass beads, soda lime glass beads, alumina beads, and mixtures thereof. In view of contamination caused by the dispersion medium being broken by collision of the dispersion medium with each other, glass beads or stabilized zirconia beads are preferably used as the dispersion medium. The size of the dispersion medium may be, for example, 0.1 to 10mm in diameter, and preferably 0.5 to 2.0mm in diameter. When the diameter of the dispersion medium is less than 0.1mm, collision energy between the pulverization media is small, and mechanochemical reaction tends to be weakened. In addition, if the diameter of the dispersion medium is larger than 10mm, collision energy between the dispersion media becomes excessive, and the dispersion medium breaks up to cause more pollution, which is not preferable.
The apparatus (pulverizing apparatus) for wet dispersion using the dispersion medium is not particularly limited as long as it is an apparatus capable of causing mechanochemical reaction of zinc oxide and/or basic zinc carbonate with cyanuric acid by adding the mixed slurry to a container into which the dispersion medium is charged and then agitating to collide the dispersion medium with zinc oxide, basic zinc carbonate and/or cyanuric acid. Examples of the method include a ball mill, a bead mill, and a sand mill such as a sand mill (AIMEX, manufactured by Kagaku Kogyo Co., ltd.), apexMill ((Kyowa Kagaku Kogyo Co., ltd.), attritor mill (manufactured by Japanese coke industry Co., ltd.), and a pearl mill (AshizawaFinetech, manufactured by Kogyo Co., ltd.), and the number of revolutions, reaction time, etc. of a device for stirring the dispersion medium may be appropriately adjusted in accordance with a desired particle size, etc.
In the obtained zinc cyanurate particle dispersion, the zinc cyanurate particles are contained in the dispersion (slurry) as a solid component thereof in the range of 0.10 to 50 mass%, 0.1 to 20 mass%, 0.1 to 10 mass%, or 0.1 to 5 mass%.
In order to reduce the particle size of the obtained zinc cyanurate particles, the zinc cyanurate particles may be subjected to a pulverization treatment step using the above pulverization treatment apparatus. The rotation speed, reaction time, etc. of the device for stirring the dispersion medium may be appropriately adjusted in accordance with the desired particle diameter, etc.
The zinc cyanurate particles obtained by this production method have a major axis length of 100nm to 800nm, a minor axis length of 10nm to 60nm, a length ratio (major axis/minor axis) of 5 to 25, and an average particle diameter of 80nm to 900nm when measured by a laser diffraction method, for example, when measured by observation with a transmission electron microscope. The specific surface area of the zinc cyanurate particles obtained by drying the aqueous slurry of zinc cyanurate particles at 110℃was 10m 2/g~100m2/g.
In addition, the raw materials in powder state solid phase reaction production method, for example, in the closed or open under 30 ~ 300 ℃ heating treatment method, the mixed powder is composed of mesh 1,000 μm sieve residues below 1% zinc oxide, cyanuric acid and water, zinc oxide relative to cyanuric acid mole ratio is 2 ~ 3, and mixed powder water content is 9 ~ 18 mass%.
The obtained zinc cyanurate particles contain about 10% by mass of water, and therefore, are subjected to a heat treatment under open conditions to remove water and form zinc cyanurate particles having a water content of less than 1.0% by mass (commercially available as, for example, trade name StarFine manufactured by Nikko chemical Co., ltd.) and can be used in a dispersion (paint additive) described later. In the case of industrial mass production, the heat treatment is preferably performed using a powder mixer having a mixing unit and a heating unit. Specific examples thereof include a heated reaction tank capable of stirring and mixing in an open or closed type, such as a vibration dryer, a henschel mixer, luo Dige mixer (LoedigeMixer), a Nauta conical screw mixer, and a rotary kiln.
In order to reduce the particle size of the obtained zinc cyanurate particles, the zinc cyanurate particles may be subjected to a pulverization treatment step using the above pulverization treatment apparatus. The rotation speed, reaction time, etc. of the device for stirring the dispersion medium may be appropriately adjusted in accordance with the desired particle diameter, etc.
In the zinc cyanurate particles obtained by the production method, for example, the screen residue having a mesh size of 400 μm is less than 10% by mass, the length of the major axis of the primary particles is 400nm to 3,000nm and the length of the minor axis of the primary particles is 10nm to 300nm when measured by a transmission electron microscope, the length ratio (major axis/minor axis) of the major axis to the minor axis is 1.3 to 300, and the average particle diameter when measured by a laser diffraction method is 0.5 μm to 20 μm. The specific surface area of the obtained zinc cyanurate particles is, for example, 10m 2/g~100m2/g.
The surface charge of the obtained zinc cyanurate particles has a negative charge in the aqueous system at a pH value in the range of 3 to 10. Therefore, the aqueous anticorrosive paint can be obtained stably, with good dispersibility in water in the acidic to alkaline region, and good compatibility with synthetic resins, emulsions, and the like when preparing the aqueous anticorrosive paint (paint composition, and the like).
< Method for producing dispersion (coating additive) >)
The method for producing the dispersion is not particularly limited, and the dispersion can be obtained, for example, by a step of mixing inorganic oxide particles with zinc cyanurate particles or a slurry thereof in a liquid medium using a pulverizing device. When the inorganic oxide particles are inorganic oxide particles, they may be subjected to a pre-pulverization treatment, and mixed with zinc cyanurate or a slurry thereof in a liquid medium using a pulverizing device to form a dispersion.

Further, since zinc cyanurate is dissolved in an acidic liquid, when zinc cyanurate particles and inorganic oxide particles are mixed, it is preferable to perform a mixing operation (wet grinding treatment) of these particles by adjusting the pH of the liquid to be alkaline to neutral. In addition, the Zeta potential (Zeta potential) of the zinc cyanurate particles is-10 mV to-1 mV when the pH value is alkaline to neutral.
In addition, when inorganic oxide particles having an isoelectric point in the pH range of 5 to 12 and having a Zeta potential of-80 mV to +80mV are used to obtain the above dispersion, the pH is adjusted so that the pH range is-5 mV to-80 mV, whereby a dispersion excellent in dispersibility can be obtained.

As shown in Table 1[ tables 1-1 to 1-4], according to the present invention, a coating film having a hardness of about 3B or more and excellent adhesion to a substrate can be formed on the whole aluminum plate substrate.
Specifically, as shown in [ tables 1 to 1] and [ tables 1 to 2] (examples 1 to 3, and examples 5 to 10), even when various silica powders, colloidal alumina, colloidal zirconia, colloidal titania, and tin oxide sols are used, a coating film which is formed on the whole of an aluminum plate substrate and has excellent adhesion to the substrate can be formed.
As shown in [ tables 1 to 3] (examples 11 to 13), even when the particle size of the zinc cyanurate particles and the (zinc oxide)/(zinc cyanurate) conversion molar ratio of the zinc cyanurate particles were changed, a coating film having a hardness of 2B or more and excellent adhesion to the substrate could be formed on the whole of the aluminum plate substrate.
As shown in tables 1 to 4 and tables 1 to 5 (examples 14 to 21 and examples 22 to 28), according to the present invention, when various resin emulsions are used, it is possible to form a coating film having both hardness and adhesion to an aluminum plate substrate as a whole.
On the other hand, in both of comparative example 1 in which zinc cyanurate slurry and resin emulsion were mixed and comparative example 2 in which zinc cyanurate slurry was wet-pulverized to form a dispersion and mixed with resin emulsion, the appearance (poor) and adhesion (D) of the coating film were much worse than those of the examples without using inorganic oxide powder. In the case of comparative example 3, which is a resin emulsion alone, the coating film appearance was good, but the adhesion was evaluated as D. In addition, when colloidal metal oxide particles and zinc cyanurate were simply mixed without forming a dispersion (comparative example 4), the coating film appearance was good but the adhesion (C) was poor.
In reference examples 1 and 2, in which the average particle diameter of the dispersoid measured by the laser diffraction method was a value exceeding 10,000nm, the appearance (poor) and adhesion (D) of the coating film were both significantly worse than those of the examples.
As shown in table 2[ tables 2-1 to 2-3] (example 4, example 29 to example 33, and example 34 to example 37), according to the present invention, when various resin emulsions are used, it is possible to form a coating film having a hardness of 2B or more and excellent adhesion to a substrate on the whole PET substrate. Further, according to the present invention, since a significant increase in the HAZE value is suppressed, adhesion to a substrate can be improved without significantly impairing the transparency of a PET substrate.
On the other hand, in both the case of comparative example 5 in which the zinc cyanurate slurry and the resin emulsion were mixed and the case of comparative example 6 in which the zinc cyanurate slurry was wet-pulverized to form a dispersion and mixed with the resin emulsion, the appearance (poor) and the adhesion (D) of the coating film were much worse than those of the examples. In the case of comparative example 4, which is a resin emulsion alone, the coating film appearance was good, but the adhesion was evaluated as D.
In addition, in reference example 3, in which the average particle diameter size of the dispersoid measured by the laser diffraction method was a value exceeding 10,000nm, in the dispersion liquid containing the inorganic oxide powder and the zinc cyanurate particles, the appearance (poor) and the adhesion (C) of the coating film were both much worse than those of the examples.
As shown in table 3[ tables 3-1 to 3-2] (examples 38 to 40, and examples 41 to 46), according to the present invention, a coating film having a hardness of 5B or more and excellent adhesion to a substrate can be formed on the entire Cu plate substrate.
On the other hand, in the case where the inorganic oxide particles were not used, although the appearance of the coating film was good in comparative example 8, the adhesion was evaluated as D, and in both the case of comparative example 9 in which the zinc cyanurate slurry and the resin emulsion were mixed and comparative example 10 in which the zinc cyanurate slurry was wet-pulverized to form a dispersion and the dispersion was mixed with the resin emulsion, the coating film appearance (poor) and the adhesion (D (comparative example 9), B (comparative example 10)) were both much worse than those of the examples.
As shown in table 4[ tables 4-1 to 4-2] (examples 47 to 49, examples 50 to 53), according to the present invention, a coating film having a hardness of 3B or more and excellent adhesion to a substrate can be formed on the entire SUS plate substrate.
On the other hand, in the case where the inorganic oxide particles were not used, in comparative example 11, which was only a resin emulsion, although the appearance of the coating film was good, the adhesion was evaluated as D, and in the case of comparative example 12, in which zinc cyanurate slurry and a resin emulsion were mixed, and comparative example 13, in which zinc cyanurate slurry was wet-pulverized to form a dispersion, and mixed with a resin emulsion, both the appearance (poor) and the adhesion (D) of the coating film were much worse than those of the examples.
As shown in table 5[ tables 5-1 to 5-2] (examples 54 to 56, and examples 57 to 63), according to the present invention, a coating film having a hardness of 3B or more and excellent adhesion to a base material can be formed on the whole mild steel sheet base material.
On the other hand, in the case where the inorganic oxide particles were not used, comparative example 14 in which zinc cyanurate slurry and resin emulsion were mixed and comparative example 15 in which zinc cyanurate slurry was wet-pulverized to form a dispersion and mixed with resin emulsion were the results of much poorer coating film appearance (poor) and adhesion (D) than in the examples.
As shown in Table 6[ tables 6-1 to 6-2] (examples 64 to 67, and examples 68 to 73), according to the present invention, a coating film having a hardness of HB or more and excellent adhesion to a substrate can be formed on the whole of a galvanized steel sheet substrate.
On the other hand, when the inorganic oxide particles were not used, the comparative example 16 in which the zinc cyanurate slurry was mixed with the resin emulsion and the comparative example 17 in which the zinc cyanurate slurry was wet-pulverized to form a dispersion and mixed with the resin emulsion were both the appearance (poor) and the adhesion (C (comparative example 16), B (comparative example 17)) of the coating film were much worse than those of the examples.
As shown in table 7[ tables 7-1 to 7-2] (examples 74 to 76, and examples 77 to 82), according to the present invention, a coating film which is formed on the entire wood and has excellent adhesion to a substrate can be formed.
On the other hand, when the inorganic oxide particles were not used, only comparative example 18 in which the resin emulsion and comparative example 20 in which the zinc cyanurate slurry was wet-pulverized to form a dispersion and mixed with the resin emulsion had good coating film appearance, but the coating film appearance was poor, and comparative example 19 in which the zinc cyanurate slurry was mixed with the resin emulsion had much poorer coating film appearance (poor) and adhesion (C) than in the examples.
Fig. 1 is a graph showing an approximation curve obtained from measurement values of Zeta potential (mV) of inorganic oxide particles with respect to pH values (pH 2 to 10 (horizontal axis)) of aqueous slurries in which the inorganic oxide powder is silica powder (fumed silica a, fumed silica B, silica powder C) or titania powder (titania powder).
As shown in fig. 1, the inorganic oxide particles used in the present example: the silica powder (fumed silica A, fumed silica B, silica powder C) and the titania powder (titania powder) each have no isoelectric point at pH5 to pH12 and have a Zeta potential of-5 mV to-50 mV in the pH range.
As described above, it was confirmed that the use of the coating additives 1 (fumed silica a), 2 (fumed silica B), 3 (silica powder C) and 4 (titania powder) of these powders all gave inorganic oxide particles having no isoelectric point at pH5 to pH12 but having Zeta potential of-5 mV to-50 mV in the pH range, and that no sedimentation layer was visually confirmed after standing at room temperature for 12 hours, and that a good dispersion state was maintained, and that a dispersion liquid having excellent dispersibility was obtained.
