Abstract

The invention provides low-cost high-temperature-resistant coating, belonging to the technical field of coating. The low-cost high-temperature-resistant coating comprises components A and components B, wherein the components A comprise the following components in percent by weight: 5-10 percent of polyvinyl butyral, 6-10 percent of black high-temperature pigment, 15-30 percent of high-temperature-resistant filler, 10-30 percent of antirust pigment, 20-40 percent of mixed solvent, 0.3-0.5 percent of dispersing agent and 0.6-1 percent of anti-settling agent; and the components B comprise the following components in percent by weight: 40-60 percent of silicate ester, 30-50 percent of alcohol solvent, 0.3-0.5 percent of industrial hydrochloric acid, 0.3-0.5 percent of activating agent and 6-10 percent of purified water. By using inorganic silicate as raw materials, in combination with high-temperature-resistant pigment, the low-cost high-temperature resistant coating which can resist more than 600DEG C is developed; and the corrosion resistance is better than the corrosion resistance of the traditional organic silicon high-temperature-resistant coating.

Description

technical field [0001] The invention provides a high-temperature-resistant coating, in particular to an organosilicon high-temperature-resistant coating, which belongs to the technical field of coatings. Background technique [0002] With the increasing cost of chemical raw materials, paint factories are pursuing the lowest cost, hoping to develop the best quality products with the lowest raw materials. Silicone high-temperature-resistant paints currently on the market have defects such as high cost and poor anti-corrosion performance. For this reason, the high-temperature-resistant paint developed by the present invention completely solves the cost, cost performance and anti-corrosion properties, and greatly reduces the coating cost for customers when using products. cost. Contents of the invention [0003] The purpose of the present invention is to provide a kind of coating that has lower cost, high temperature resistance, adopts following technical scheme: [0004] A ...
