Problems solved by technology

However, the current conventional water-based polysiloxane imitation porcelain coatings have disadvantages such as poor stability, long curing time and short storage time after curing, and the viscosity of the coating is low after curing, and it is prone to sagging. Heating the substrate to 40°C to 60°C before spraying, thus limiting the high-efficiency and large-scale application and development of water-based polysiloxane imitation porcelain coatings

preparation example Construction

[0021] The preparation method of water-based polysiloxane imitation porcelain coating of the present invention is as follows:

[0022] (1) Mix and stir the substances in the A component evenly, grind and filter to obtain a colloid with a particle size of less than 20 microns, and set aside.

[0023] (2) Mix and grind the colloid, component B and component C of component A, mix according to the mass ratio of 10: (1~10): (0.1~5), stir evenly, and ultrasonic for 5 minutes, The finished product of water-based polysiloxane imitation porcelain paint can be obtained.

Embodiment 1

[0025] A water-based polysiloxane enamel paint is composed of A component, B component and C component, and the contents of each component are as follows:

[0026] Component A: 60g silica hydrosol (solid content: 30%), 20g talcum powder, 15g copper chrome black, 2g carbon black, 1g hydrophilic nano-silica, 1g nano-potassium aluminum silicate, 0.5 BYK110 dispersant g, BYK333 leveling agent 0.5g.

[0027] B component: Glacial acetic acid 10g.

[0028] Component C: 20 g of methyltrimethoxysilane.

[0029] After mixing and stirring all the materials in the above-mentioned component A, grind and filter to obtain a colloid with a particle size of 10-20 microns, which is set aside. Then mix and grind the colloid of component A, component B and component C according to the mass ratio of 10:1:2, and ultrasonicate for 5 minutes to obtain the finished water-based polysiloxane imitation porcelain coating.

Embodiment 2

[0031] A water-based polysiloxane enamel paint is composed of A component, B component and C component, and the contents of each component are as follows:

[0032] Component A: 70g titanium oxide hydrosol (solid content: 30%), 10g calcium carbonate, 15g titanium dioxide, 2g cellulose, 2.8g bentonite, 0.1g BYK110 dispersant, 0.1g BYK333 leveling agent.

[0033] B component: hydrochloric acid aqueous solution 20g (concentration 1%).

[0034] Component C: 30g of dimethyldimethoxysilane, 20g of methyltriethoxysilane.

[0035] After mixing and stirring all the materials in the above-mentioned component A, grind and filter to obtain a colloid with a particle size of 10-20 microns, which is set aside. Then mix and grind the colloid, component B and component C according to the mass ratio of component A to 10:2:5, mix and stir evenly, and ultrasonicate for 5 minutes to prepare the water-based polysiloxane imitation porcelain coating finished product.

Abstract

The invention relates to the technical field of coatings, in particular to a water-based polysiloxane ceramic simulating coating. The water-based polysiloxane ceramic simulating coating is composed ofa component A, a component B and a component C, wherein the component A is composed of water-based nano sol, filler, pigment, an anti-sagging agent, a leveling agent and a dispersing agent, the component B is a catalyst, the component C is a silane coupling agent, and the mass ratio of the component A to the component B to the component C is 10: (1-10): (0.1-5). The water-based polysiloxane ceramic simulating coating has the advantages of being good in stability before curing, simple in curing process, short in curing time, capable of being sprayed at normal temperature, long in shelf life after curing, resistant to hot and cold circulation, high in hardness, resistant to corrosion and the like, and can meet the requirement for long-term use of various metal base materials in complex andchangeable environments.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based polysiloxane imitation porcelain coating. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil or emulsion, adding pigments, fillers and corresponding additives, using organic solvents Or viscous liquid prepared from sodium alkylbenzene sulfonate. Porcelain-like paint is a kind of architectural paint with a decorative effect similar to enamel finish. It can be painted and sprayed on metal, plastic, cement floor, wood and other solid surfaces. It is widely used in public building interior walls, residential interior walls, kitchens, Spraying decoration of bathrooms and anticorrosion of electrical appliances, machinery and furniture exterior decoration. [0003] In recent years, there are many kinds of ceramic-li...
