Embodiment 1

[0044] The preparation of embodiment 1 white high-gloss baking varnish coating

[0045] The parts by weight of each composition of coating are:

[0046]

[0047]

[0048] Except for the amino resin, the other raw materials are added within 30 minutes, and stirred at a high speed at 2000rpm for 30 minutes;

[0049] Then add the amino resin and continue stirring for 20 minutes to form the coating.

[0050] When in use, the coating obtained in Example 1 is sprayed on the coating film formed on the surface of the sanitary ware, and cured at 180°C for 40 minutes to obtain a high-gloss, wear-resistant, and stain-resistant fluorosilicone-modified acrylic organic-inorganic nanosilica Resin white baking lacquer coating.

[0051] See Table 1 for the performance data of the coating formed by the coating prepared by the method of Example 1.

Embodiment 2

[0052] The preparation of embodiment 2 colored matte baking varnish coatings

[0053] The parts by weight of each composition of coating are:

[0054]

[0055] Except for the amino resin, the other raw materials were added within 30 minutes, and stirred at a high speed at 2000rpm for 30 minutes; then the amino resin was added, and the stirring was continued for 20 minutes.

[0056] During use, the coating obtained in Example 2, when spraying, according to the ambient temperature and spraying requirements, add a certain amount of the above-mentioned organic solvent as a diluent to adjust the viscosity of the coating, and spray the coating film formed on the surface of the sanitary ware at 180 ° C. After curing for 40 minutes, a wear-resistant and stain-resistant fluorosilicone-modified acrylic organic-inorganic nano-silicon hybrid resin color matte baking varnish coating can be obtained; the level of gloss can control the amount of matte powder added.

[0057] See Table 1 f...

Embodiment 3

[0058] Embodiment 3 Two-component room temperature curing white coating (paint for repair)

[0059] The parts by weight of each composition of coating are:

[0060] A component:

[0061]

[0062] B component:

[0063] Curing agent (3390-BYK) (70% xylene solution) 15 parts

[0064] 3390-BYK: Hexamethylene polyisocyanate of aliphatic polyisocyanate

[0065] Organic solvents:

[0066] 15 parts of propylene glycol-butyl ether

[0067] Butyl acetate 5 parts

[0068] Propylene glycol-methyl ether acetate 30 parts

[0069] The ratio of the above-mentioned organic solvents can be adjusted according to the ambient temperature to facilitate the use in different seasons.

[0070] This embodiment 3 is a two-component package with external curing agent. When using it, add the hexamethylene polyisocyanate (3390) curing agent of BYK’s aliphatic polyisocyanate in proportion, and add a certain amount of diluent according to the viscosity of spraying , mechanical stirring for 10 minu...

Abstract

The invention relates to a paint for coating the surface of a sanitary ware made of composite materials, which comprises the following components in percentage by weight: 40-86% of silicon fluoride modified acrylic acid / organic-inorganic nano-silicon hybrid resin, 1.7-20% of curing agent, 3-35% of organic solvent, 8-15% of pigment / padding and 0.5-3% of assistant, wherein the curing agent is selected from amine resin or Bayer curing agent 3390. The invention also provides a preparation method of the paint for coating the surface of the sanitary ware made of composite materials, which has mild reaction conditions, easy control and large material property regulating range. After the obtained paint is coated on the surface of the sanitary ware made of composite materials, the surface is smooth, flat, non-viscous and transparent, has good glossiness and strong adhesive force, can not be stripped and chapped easily, and has high surface hardness, wear resistance, high temperature resistance, ageing resistance, boiling water resistance and strong hydrophobic property. Moreover, chemical substances and various chemical solvents capable of resisting acids, alkalis, salts and the like can provide a protective barrier for substrates and are especially suitable for coating the surface of the sanitary ware made of composite materials.

Description

technical field [0001] The invention relates to a coating; in particular, it relates to a coating for coating the surface of a composite material sanitary ware and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and the needs of social progress, people have higher and higher requirements for the functions of sanitary products used at home. Ordinary glaze microscopes observe the roughness, and generally obvious micro-cracks and air holes can be seen on the surface. If water is sucked into the coating, it will expand to a certain extent, which will easily cause the paint on the surface of the sanitary ware to shell and crack due to expansion, especially for products with high water absorption such as toilets, which will easily remove dirt and odors from the water. Inhale the paint film, and after a long time of use, it will produce dirt and odor that cannot be removed. Bacteria are particularly easy to survive, mul...
