Abstract

The invention discloses a high temperature resistant coating and a preparation method thereof. The high temperature resistant coating is composed of an A component and a B component, wherein the A component is as follows: 65-68 parts of acrylic resin, 42-45 parts of bisphenol A epoxy resin, 20-25 parts of castor oil, 18-24 parts of mica powder, 12-16 parts of benzyl silicon resin, 20-25 parts of silicone resin, 2-4 parts of defoaming agent, and 45-50 parts of solvent; the B component is as follows: 2-4 parts of rust-inhibiting additive, 10-12 parts of flatting agent, 2-5 parts of catalyst, 8-12 parts of pigment, and 11-13 parts of surfactant. The invention further provides the preparation method of the coating. The coating is not only strong in high temperature resistance and good in fire prevention and corrosion resistance, but also good in adhesion and hard to fall off; the coating is small in surface friction coefficient, friction resistant, various in colors, long in service life, wide in use range, environment-friendly and lowered in cost.

Description

Technical field [0001] The invention involves a coating, which is specifically a high -temperature -resistant coating and its preparation method. Background technique [0002] In industrial production, many machines and equipment run at high temperature, so high temperature corrosion is worthy of attention.In various high -temperature anticorrosive technologies, high -temperature -resistant coatings have unique superiority, so high -temperature -resistant coatings are widely used in high -temperature anticorrosive fields. [0003] At present, high -temperature coatings can be widely used in various high -temperature -resistant equipment in electrical, metallurgy, oil, aviation, chemical, medicine, food and other industries (such as: heaters, high -power lighting, heating pipelines, automobiles and motorcycles muffles, and motorcycles, and motorcycles.High temperature furnace, chimney, etc.).Although it is more environmentally friendly than oily coatings, its promotion is limited ...
