Cubic silicon carbide anticorrosive wear-resistant coating and preparation method thereof

Abstract

The invention discloses a cubic silicon carbide anticorrosive wear-resistant coating. The cubic silicon carbide anticorrosive wear-resistant coating is prepared from the following raw materials in parts by mass: 40-60 parts of water-based resin, 10-20 parts of deionized water, 10-20 parts of titanium dioxide, 2-6 parts of cubic silicon carbide micro-powder, 5-10 parts of a filler, 0.1-0.5 part ofa defoaming agent, 0.1-0.5 part of a wetting agent, 0.05-0.2 part of a thickening agent and 0.2-0.6 part of a water-based drier. The invention also discloses a preparation method of the cubic siliconcarbide anticorrosive wear-resistant coating. The preparation method comprises the following steps: preparing a mixture by a step-by-step method, adding deionized water and assistants, and carrying out dispersing and filtering to obtain the coating. According to the coating, the water-based resin is used as a film-forming substance, so a curing agent is not required to be added, and the corrosionresistance and wear resistance of the coating are improved; the method provided by the invention is beneficial for full and uniform mixing of the components, ensures full play of the effects of the assistants, and does not need heating in the preparation process; and the coating can be used without blending, so the application range of the coating is enlarged.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a cubic silicon carbide anti-corrosion and wear-resistant coating and a preparation method thereof. Background technique [0002] The paint industry is a modern industry. But the paint itself has a long history. In the middle of the 19th century, with the emergence of synthetic resins, the film-forming substances of paints underwent a fundamental change, forming the period of synthetic resin paints. Since the founding of New China, along with the development of various industries in the national economy, the coating industry as a supporting tool has gradually developed from a very inconspicuous small industry to an indispensable and important industry in various fields of the national economy. After several generations of hard work and pioneering spirit, my country has become the world's second largest producer and consumer of paint, and has entered the mainstream of the world'...

AI Technical Summary

Problems solved by technology

Existing water-based coatings have poor wear resistance, and the paint film is easily damaged, which is difficult to meet people's needs

The Chinese patent with the application number 201711346106.7 discloses a wear-resistant water-based paint. The water-based paint uses acetone as a viscosity reducer. Acetone is colorless, transparent and highly volatile, and acetone is flammable and toxic. Long-term exposure can damage human liver and kidneys. cause damage; 1,6-hexamethylene diisocyanate and isophorone diisocyanate are used to improve the hardness, wear resistance and shorten the drying time of the coating film, but the above two are toxic substances, which will not only cause harm to human health, After volatilization, it will cause great pollution to the environment

The Chinese patent with application number 201810935740.2 discloses a wear-resistant water-based coating and its preparation method. ABS resin and polyvinyl chloride resin are used to improve the wear resistance and corrosion resistance of the water-based coating. However, ABS resin and polyvinyl chloride resin are used in The reaction cannot be carried out at room temperature, and heating treatment is necessary. If the heating temperature is too low, the resin cannot be dissolved and dispersed uniformly, resulting in the failure of the reaction. If the temperature is too high, the resin will be decomposed and cannot exert its anti-corrosion and wear-resisting effect.
