Abstract

The present invention provides a single-liquid-type fluorocarbon coating comprising the following components by weight: 40 to 55 parts of a fluorocarbon emulsion, 3 to 6 parts of a diluent, 0.3 to 0.4 part of a wetting agent, 0.2 to 0.7 part of a dispersing agent, 0.1 to 0.6 part of a defoamer, 0.4 to 0.9 part of a thickening agent, 10 to 15 parts of a filler, 15 to 20 parts of a pigment, 20 to 25 parts of water, 1 to 3 parts of nano magnesium oxide and 2 to 4 parts of nano-zinc hydroxide. The present invention also provides a preparation method of the single-liquid-type fluorocarbon coating. The single-liquid-type fluorocarbon coating has good acid and alkali resistance and hardness.

Description

Technical field: [0001] The invention relates to a coating, in particular to a single-liquid fluorocarbon coating 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—weather resistance, heat resistance, low temperature resistance, and chemical resistance due to the high electronegativity of the introduced fluorine element and strong carbon-fluorine bond energy. , and has a unique non-stick and low friction. 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 products. After paint, it is one of the paints with the highest comprehens...
