Abstract

The invention discloses a fluorocarbon paint for exterior walls, which comprises the following components by weight fraction: 35-45 parts of water-based fluorocarbon resin; 1-2 parts of film-forming aid; 1-1.5 parts of diethylenediamine; thickener 0.5-1 part; pH adjuster 0.1-0.3 part; dispersant 0.5-1 part; titanium dioxide 10-16 part; cellulose acetate paddle 5-10 part; butyl acetate 3-5 part; preservative 0.5-1 part ; 3‑4 parts of defoamer; 20‑30 parts of pure water. The fluorocarbon paint for exterior walls of the invention has the advantage of strong crack resistance.

Description

technical field [0001] The invention relates to an exterior wall fluorocarbon paint and a preparation method thereof. Background technique [0002] Fluorocarbon coatings refer to coatings with fluororesin as the main film-forming substance; also known as fluorocarbon coatings, fluorine coatings, fluororesin coatings, etc. Among all kinds of coatings, fluororesin coatings have particularly superior properties due to the high electronegativity of the introduced fluorine element and strong carbon-fluorine bond energy. Weather resistance, heat resistance, low temperature resistance, chemical resistance, and has unique non-stick and low friction properties. After decades of rapid development, fluorine coatings have been widely used in various fields such as construction, chemical industry, electrical and electronic industry, machinery industry, aerospace industry, and household goods. It has become the coating brand with the highest comprehensive performance after high-performa...
