Hereinafter, the present invention will be described in detail.
In order to achieve the above object, the present invention provides an antimicrobial and scratch-resistant resin composition containing an organic-based composition comprising an inorganic composition containing a ceramic powder, a mixed resin obtained by mixing a polyester resin and a polyurethane resin, scratch self-restitution organic-inorganic hybrid coating composition.
It is preferable that the organic / inorganic hybrid coating composition comprises 5 to 20% by weight of the inorganic composition and 80 to 95% by weight of the organic composition. If the content of the inorganic-based composition is less than 5% by weight, the extinction effect and the viscosity-increasing effect of the inorganic-based composition are hardly exhibited. If the content of the inorganic-based composition exceeds 20% by weight, the flowability of the coating composition is lost A problem arises. Therefore, the content of the inorganic-based composition in the organic-inorganic hybrid coating composition is preferably 5 to 20% by weight. On the other hand, if the content of the organic-based composition is less than 80% by weight, it is difficult for the scratch self-restoring force and resistance to exhibit the elastic action and the scratch self resistance according to the resin properties of the mixed resin obtained by mixing the polyester resin and the polyurethane resin, If the content of the organic-based composition exceeds 95% by weight, the inorganic component of the coating composition decreases and the surface hardness decreases. Therefore, the content of the organic-based composition in the organic-inorganic hybrid coating composition is preferably 80 to 95% by weight.
The coating composition of the present invention can be applied to conventional hard materials such as automobile parts, home appliances and household goods, but it is also applied to a wearable device having flexible properties which have been recently commercialized Accordingly, in the present invention, a hybrid coating composition capable of simultaneously exhibiting the flexibility and elasticity of the organic-based composition and the viscosity-increasing effect and the surface hardness-improving ability of the inorganic-based composition at the same time, has been developed. However, in order for such hybrid performance to be well realized in the coating film formed on the coating-coated product, the ratio of the content of the inorganic composition to that of the organic composition is very important. The present inventor has repeatedly conducted experiments As a result, the optimum content ratio of the organic and inorganic compositions as described above was derived. As described above, according to the optimum content ratio provided in the present invention, it is possible to form a coating film having surface hardness such that the self-restoration performance against scratches can be properly realized, and the appropriate viscosity of the coating composition is maintained The reproducibility of the self-restoration performance against the scratch can be secured.
In the present invention, the ceramic powder basically acts as a quenching agent to improve the quenching effect by reducing the gloss of the coating film, but it may increase the viscosity of the coating composition and improve the dispersibility and durability. When the fine ceramic powder is dispersed in the polymer resin solution, it becomes fine aggregated particles. When it is coated on the substrate, it forms irregularities on the surface of the coating film by drying and curing, so that the incidence angle does not allow complete specular reflection and diffuse reflection can make our eyes not feel light have. In the present invention, the ceramic powder may be a mixed powder of silicon dioxide (SiO 2 ) and titanium dioxide (TiO 2 ), but is not limited thereto. Preferably, the average particle diameter of the silicon dioxide and titanium dioxide mixed powder is 2 to 5 μm, and the average particle size of the pulverized particles is preferably equal to the average particle size of the powder mixture.
In the present invention, the inorganic-based composition may further include a silane coupling agent, a thickener, an antibacterial agent, and a solvent.
The silane coupling agent may be at least one selected from the group consisting of amino silane, epoxy silane, phenyl silane, and tetraethoxy silane. . By using a silane coupling agent, the reactivity and the adhesive strength of the composition can be improved.
The thickening agent may be methyl cellulose or hydroxyethyl cellulose. The use of such a thickener can promote aggregation of the composition.
The antibacterial agent may be vegetable oil, but is not limited thereto.
As a solvent for dissolving the inorganic composition, a mixed solvent of isopropyl alcohol (IPA) and distilled water (H 2 O) may be used, but not limited thereto. The use of such a solvent may impart fluidity to the coating film have.
In the present invention, it is preferable that 3 to 8 parts by weight of a mixed powder of silicon dioxide and titanium dioxide, 5 to 10 parts by weight of a
If the amount of the mixed powder of silicon dioxide and titanium dioxide is less than 3 parts by weight, the quenching effect and durability may not be exhibited when the coating film is formed. If the amount is more than 8 parts by weight, the viscosity may increase sharply or gel- There is a problem that it is broken. Therefore, the content of the mixed powder of silicon dioxide and titanium dioxide is preferably 3 to 8 parts by weight based on 100 parts by weight of the inorganic composition.
When the amount of the silane coupling agent is less than 5 parts by weight, the surface hardness is weak. When the amount is more than 10 parts by weight, bubbling or peeling may occur. Therefore, the amount of the silane coupling agent is preferably 5 to 10 parts by weight based on 100 parts by weight of the inorganic composition.
If the amount of the thickener is less than 1 part by weight, it is difficult to expect a viscosity increase effect due to the use of the thickener. If the amount of the thickener is more than 3 parts by weight, the fluidity may greatly decrease due to high viscosity. Therefore, it is preferable that the viscosity increasing agent is 1 part by weight to 3 parts by weight based on 100 parts by weight of the inorganic composition.
If the amount of the antimicrobial agent is less than 0.1 parts by weight, the antimicrobial effect of the coating composition may not be exhibited. If the amount of the antimicrobial agent is more than 1 part by weight, the cost of the coating composition including the coating composition may increase. Therefore, the antibacterial agent is preferably 0.1 to 1 part by weight based on 100 parts by weight of the inorganic composition.
If the isopropyl alcohol content is less than 40 parts by weight, the reaction of the coating composition may be uneven and the reproducibility may be deteriorated. If the content is more than 60 parts by weight, a coating film forming ability of the coating composition may be insufficient. Therefore, isopropyl alcohol is preferably 40 to 60 parts by weight based on 100 parts by weight of the inorganic composition.
If the amount of the distilled water is less than 10 parts by weight, the hydrolysis reaction may be slow and the coating film may not be densely formed. If the amount is more than 20 parts by weight, the reaction rate of the coating composition may be too fast. Therefore, the distilled water is preferably 10 parts by weight to 20 parts by weight per 100 parts by weight of the inorganic composition.
In the coating composition of the present invention, the organic-based composition may include a mixed resin obtained by mixing a polyester resin and a polyurethane resin. Polyester resin and polyurethane resin are excellent in flexibility and elasticity when used as a coating material for a coating film, thereby enabling self-restoration to scratch on the surface of a coating film and providing effects such as scratch resistance. However, with such a polymer organic- In order to solve such a problem, in the present invention, the inorganic-based composition containing the ceramic powder and the organic polymer resin composition are mixed to form an organic-inorganic hybrid coating The inventors of the present invention have discovered a coating composition and a coating agent which have strong self-restoration and antimicrobial properties against scratches.
In addition, the organic-based composition may further include an additive and a solvent.
The additive may be an anti-pollution agent, a dispersant, an anti-settling agent or a leveling agent. The anti-settling agent prevents the coagulation of the coating composition, and the anti-settling agent prevents the coagulation and sedimentation of the coating composition during storage, The leveling agent induces formation of a smooth coating film.
Examples of the solvent for dissolving the organic composition include methyl ethyl ketone (MEK), cyclohexane, isopropyl alcohol (IPA), methyl isobuthyl ketone (MIBK), toluene toluene, butyl acetate, and xylene (xylene) may be used, but the present invention is not limited thereto.
In the present invention, the optimum content ratio of each component and the components constituting the organic-based composition is 20 to 40 parts by weight of a polyester resin, 15 to 25 parts by weight of a polyurethane resin, 3 to 10 parts by weight of cyclohexane, 5 to 10 parts by weight of cyclohexane, 5 to 10 parts by weight of isopropyl alcohol, 3 to 5 parts by weight of methyl isobutyl ketone, 5 to 10 parts by weight of toluene, 2 to 5 parts by weight of butyl acetate, To 5 parts by weight, and 3 to 7 parts by weight of an additive.
If the content of the polyester resin is less than 20 parts by weight, adhesion of the coating film and scratch resistance may be deteriorated due to insufficient resin content. If the content of the polyester resin exceeds 40 parts by weight, the viscosity of the coating composition may be lowered, . Therefore, the polyester resin is preferably 20 to 40 parts by weight based on 100 parts by weight of the organic-based composition.
If the content of the polyurethane resin is less than 15 parts by weight, scratch self-resilience of the surface of the coating film is difficult to achieve. If the content of the polyurethane resin exceeds 25 parts by weight, drying may be accelerated and coating workability may be deteriorated. Therefore, the polyurethane resin is preferably 15 parts by weight to 25 parts by weight based on 100 parts by weight of the organic-based composition.
Also, it is preferable to use a solvent in which 3 to 10 parts by weight of methyl ethyl ketone, 5 to 10 parts by weight of cyclohexane, 5 to 10 parts by weight of isopropyl alcohol, 3 to 5 parts by weight of methyl isobutyl ketone, 5 to 10 parts by weight of toluene, By weight and xylene in an amount of 3 to 5 parts by weight, when the content of each of the mixed solvent components is less than the above-mentioned values, the components of the organic-based composition are not dissolved properly, , The self-restoring force and resistance to scratches may be lowered when the value exceeds the above-described value. Accordingly, the content of the mixed solvent with respect to 100 parts by weight of the organic-based composition is preferably 3 to 10 parts by weight of methyl ethyl ketone, 5 to 10 parts by weight of cyclohexane, 5 to 10 parts by weight of isopropyl alcohol, 3 to 5 parts by weight of methyl isobutyl ketone 5 to 10 parts by weight of toluene, 2 to 5 parts by weight of butyl acetate, and 3 to 5 parts by weight of xylene.
If the amount of the additive composed of the anti-pollution agent, dispersant, anti-settling agent or leveling agent is less than 3 parts by weight, the anti-staining property, dispersibility and leveling property of the coating composition are hard to be exerted, And the surface of the coating film may not be smooth. If the amount of the additive is more than 7 parts by weight, adhesion performance of the coating film may be deteriorated. Therefore, the amount of the additive is preferably 3 parts by weight to 7 parts by weight based on 100 parts by weight of the organic-based composition.
The antibacterial and scratch self-restraining organic / inorganic hybrid coating composition of the present invention comprises 3 to 8 parts by weight of a mixed powder of silicon dioxide and titanium dioxide, 5 to 10 parts by weight of a silane coupling agent, 1 to 3 parts by weight of a silane coupling agent, 20 to 40 parts by weight of a polyester resin, 20 to 40 parts by weight of a polyurethane resin, 10 to 20 parts by weight of an antimicrobial agent, 40 to 60 parts by weight of an isopropyl alcohol and 10 to 20 parts by weight of an antimicrobial agent, 15 to 25 parts by weight of methyl ethyl ketone, 3 to 10 parts by weight of cyclohexane, 5 to 10 parts by weight of isopropyl alcohol, 3 to 5 parts by weight of methyl isobutyl ketone, 5 to 10 parts by weight of toluene, 2 to 5 parts by weight of acetate, 3 to 5 parts by weight of xylene and 3 to 7 parts by weight of an additive, At room temperature, a mixture ratio of content of 5 to 20% by weight of the organic-based composition of 80 to 95% by weight for 4 to 10 hours can be produced through a simple production process with stirring at 200 to 400 rpm.
