Problems solved by technology

However, epoxy resin materials have deficiencies in heat resistance, wear resistance, dimensional stability, brittleness, etc., which affect their application.
In order to improve the quality of coatings, people add nano-ceramic powders to coatings to improve the overall physical and chemical properties of coatings. Although certain effects have been achieved, the dispersion effect is not good due to the small particles of nano-ceramic powders and easy agglomeration. Corresponding There is still a lot of room for improvement in the improvement of the mechanical and other qualities of coatings. For this, people will carry out surface modification treatment when filling and using it. The most common method is to use silane coupling agent for surface coupling modification treatment. Although The filling quality of nano-ceramic powder has been improved, but with the continuous improvement of people's requirements for coating performance, conventional surface modification methods have been unable to meet the needs of design and use.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a preparation method of a temperature-resistant and wear-resistant ceramic resin coating. Background technique [0002] Coatings are widely used in modern people's lives, which can not only improve the appearance of parts and products, but also improve their quality of use. Epoxy resin has excellent bonding, corrosion resistance, insulation and other properties, and is widely used in coatings. Due to the characteristics of high strength and low density, epoxy resin composite materials have gradually become one of the indispensable basic materials in the industrial field. However, epoxy resin materials have deficiencies in heat resistance, wear resistance, dimensional stability, brittleness, etc., which affect their application. In order to improve the quality of coatings, people add nano-ceramic powders to coatings to improve the overall physical and chemical properties of c...
