Problems solved by technology

Although adding a certain amount of glass glaze enhances the cohesion between the powders and improves the wear resistance of the coating, the coating prepared by spraying cannot completely discharge the air, and there are a large number of pores, which cannot be achieved even after high temperature sintering. To improve, glass glaze needs to be painted many times, the construction is complicated, and chromium is toxic to the human body, so it is not suitable to use in large quantities

Embodiment Construction

[0014] An oil-resistant and wear-resistant coating material, prepared from the following raw materials in parts by weight (kg): aluminum oxide 5, glass glaze 12, vinyl triethoxysilane 13, zirconia ceramic powder 70, aluminum sol 8, Copper oxide 2, graphene 6, appropriate amount of absolute ethanol, and appropriate amount of deionized water.

[0015] The oil-resistant and wear-resistant coating material is prepared by the following specific steps:

[0016] (1) Add an appropriate amount of absolute ethanol to the glass frit, wet ball mill it in a planetary ball mill for 5 hours, dry it at 100°C after ball milling, then add it to the sintering furnace and pre-fire it at 500°C for 20 minutes, after cooling Then add an appropriate amount of binder to make a fine powder with a particle size of 10 μm, and dry it for later use;

[0017] (2) Mix vinyltriethoxysilane, heptadecylfluorodecyltrimethoxysilane, deionized water and absolute ethanol in a volume ratio of 4:2:6:90, then add ace...

Abstract

The invention discloses an oil-resistant wear-resistant coating material, which is prepared from the following raw materials (by weight): 5-8 parts of aluminium oxide, 12-15 parts of glass glaze, 13-15 parts of triethoxyvinylsilane, 70-80 parts of zirconia ceramic powder, 8-10 parts of alumina sol, 2-3 parts of copper oxide, 6-8 parts of graphene, a proper amount of anhydrous ethanol and a proper amount of deionized water. By ingenious utilization of adhesion property of glass glaze, the coating has good adhesion with a base material. The prepared coating contains no toxic or harmful substances, has high strength, is simple to prepare, is low-cost, and has a wide range of application.

Description

technical field [0001] The invention relates to the technical field of ceramic coatings, in particular to an oil-stain-resistant and wear-resistant coating material. Background technique [0002] Exhaust equipment plays an important role in kitchens, laboratories, factories and other fields. Generally, it can be divided into exhaust hood, air duct, dust removal and purification equipment, fan, equipment shell and other parts. Among them, the materials of dust removal and purification equipment are different according to different fields. Most of them will use alloy materials. The performance of alloy materials greatly affects the use effect and life of equipment. The thermal stress generated by the ceramic coating during the friction process is relatively small, and the coating is not prone to severe fracture. It has the characteristics of low porosity, low friction coefficient, high thermal conductivity, corrosion resistance, and high hardness. It is suitable for high temp...
