Problems solved by technology

[0002] At present, various types of aluminum profiles and curtain wall coatings, mixed coatings, and paints on the market use methanol or substances containing formaldehyde and benzene as the main additives or neutralizers for coatings. Formaldehyde and benzene are toxic substances. Volatile substances of formaldehyde and benzene pollute the environment and harm human health
However, these traditional aluminum profiles and curtain wall coatings still have the disadvantages of low hardness, poor wear resistance, high energy consumption, low aging resistance and high manufacturing cost.

Abstract

The invention relates to aqueous fluorocarbon resin paint. The aqueous fluorocarbon resin paint is suitable for an aluminum section and a curtain wall. The aqueous fluorocarbon resin paint is prepared from 40-60 parts by weight of aqueous fluorocarbon resin, 1-2 parts by weight of an aqueous auxiliary agent, 8-10 parts by weight of aqueous melamine resin, 10-30 parts by weight of an inert high temperature eco-friendly pigment, 5-8 parts by weight of diethylene glycol monobutyl ether, 8-15 parts by weight of ethanol and 10-20 parts by weight of water. The aqueous fluorocarbon resin paint has the advantages of no pollution, environmental protection, safety, energy saving, low manufacture and use cost, good hardness, good wear resistance and good aging resistance.

Description

technical field [0001] The invention relates to a water-based fluorocarbon resin paint, which is especially suitable for aluminum profiles and curtain walls. Background technique [0002] At present, various types of coatings, mixed coatings, and paints for aluminum profiles and curtain walls on the market use methanol or substances containing formaldehyde and benzene as the main additives or neutralizers for coatings. Formaldehyde and benzene are toxic substances. Volatile matter of formaldehyde and benzene pollute the environment and harm human health. However, these traditional aluminum profiles and curtain wall coatings still have the disadvantages of low hardness, poor wear resistance, high energy consumption, low aging resistance and high manufacturing cost. How to solve the above-mentioned problems of existing aluminum profiles and curtain wall coatings at low cost and without pollution is an urgent and widely pursued goal by researchers.
