Heat-proof wear-proof nano anti-corrosion coating material

Abstract

The invention provides a heat-proof wear-proof nano anti-corrosion coating material. The heat-proof wear-proof nano anti-corrosion coating material is prepared from the following components in parts by weight: 40 to 60 parts of epoxy resin emulsion, 20 to 30 parts of modified organic silicon resin, 6 to 12 parts of modified nano titanium nitride, 5 to 10 parts of bentonite, 10 to 16 parts of ceramic powder, 10 to 16 parts of graphite powder, 2 to 6 parts of a coalescing agent, 0.1 to 0.5 parts of a dispersing agent, 0.6 to 1.2 parts of pigment, 0.1 to 0.5 part of a defoaming agent and 20 to 30parts of water, wherein the modified organic silicon resin is mainly prepared from organic silicon resin, acrylic acid, an initiator and silica sol; the modified nano titanium nitride is mainly prepared from nano titanium nitride and sodium dodecyl sulfonate. The heat-proof wear-proof nano anti-corrosion coating material provided by the invention not only is good in corrosion resistance, but alsohas very good heat-proof and wear-proof properties.

Description

technical field [0001] The invention belongs to the technical field of nanometer materials, and in particular relates to a heat-resistant and wear-resistant nanometer anti-corrosion coating. Background technique [0002] With the development of machinery industry, the working environment of many equipments is becoming more and more diverse. Some equipment needs to work in a hot environment, some equipment needs to work under severe wear and tear, and some mechanical equipment needs to work under both conditions at the same time. If you work under these working conditions without taking anti-corrosion measures, the mechanical equipment will be corroded quickly, which will cause damage to the mechanical equipment, seriously cause production accidents, and cause personal harm. In order to improve the anti-corrosion ability of mechanical equipment, anti-corrosion technology has become one of the important research contents in the field of coating research at home and abroad.

Problems solved by technology

Due to the high brittleness of epoxy resin cured products, poor impact resistance, acid and alkali resistance, flexibility and temperature resistance, the application of epoxy resin coatings is limited. One of the key points of research, and in order to improve its mechanical properties, various inorganic fillers such as bentonite and graphene are often added therein, but these inorganic fillers have poor compatibility with epoxy resin, which easily causes poor storage stability of the coating. And it is easy to form agglomerates, which reduces the quality of the coating, and the adhesion level between the traditional water-based epoxy resin coating and the substrate is 2, although it can meet the requirements for the coating film in actual production and life, but for some coatings that need to be wiped frequently For substrates with poor surface smoothness, a stronger peel strength is still required to meet the durable protection of the substrate
