Abstract

The invention discloses a high temperature resistant powder coating, which comprises the following components: 250 to 35 weight parts of silicone resin, 1 to 3 weight parts of texture agent, 60 to 100 weight parts of high temperature resistant filling, and 1 to 5 weight parts of deaerating agent. Compared with the prior art, the invention has a luster-preserving ratio higher than or equal to 50 percent and an adhesive force smaller than or equal to second grade under condition of high temperature roasting at 500 DEG C for 24 hours, and the temperature resistance is greatly increased.

Description

technical field [0001] The invention belongs to powder coatings, in particular to high temperature resistant powder coatings. Background technique [0002] High-temperature-resistant powder coatings refer to coatings that can withstand temperatures above 200°C for a long time without discoloration or damage to the coating film, and can still maintain appropriate physical and mechanical properties to play a protective role. Heat-resistant coatings are widely used in high-temperature parts of mechanical equipment. Usually, high-temperature-resistant powder coatings are simply improved on the basis of existing ordinary powder coatings, so they have disadvantages such as low gloss retention and poor mechanical properties. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-temperature-resistant powder coating that can withstand high temperatures above 500°C for a long time. [0004] The technical solution of the ...
