Abstract

The invention discloses an intumescent steel structure fireproof powder coating, which is composed of the following raw materials in parts by weight: epoxy resin E-12 50-60, polyester resin DC-191, fatty alcohol polyoxyethylene ether sodium sulfate 2.0-2.5, benzoin 0.2-0.6, nano-attapulgite 10-13, antiscorch agent CTP 1-2, antimony trioxide 2-3, talcum powder 4-5, aminopropyltriethoxysilane 2-3 , Antioxidant 1010 0.6-1, Diethylenetriamine 10-16, Composite filler 10-20; The impact resistance and other physical properties of the coating have been greatly improved, and the quality of the product has been improved.

Description

technical field [0001] The invention mainly relates to a coating, in particular to an intumescent fireproof powder coating for steel structures. Background technique [0002] The largest growth areas of my country's powder coating coating market are: shipbuilding industry and pipeline industry. The existing problem is that the impact resistance and hygroscopicity need to be improved and improved, and the researchers focus on the modification of various base materials. Domestically produced pipeline anti-corrosion epoxy powder coatings still have a certain gap compared with foreign high-quality products in terms of storage stability and coating workability. Therefore, continuously improving the comprehensive quality of powder coatings is an important development direction of coatings research. Contents of the invention [0003] The purpose of the present invention is to provide an intumescent steel structure fireproof powder coating. [0004] The present invention is ach...
