Abstract

The invention discloses a low-carbon waterborne coating. The coating comprises components in parts by weight as follows: 40-80 parts of a basic material, 18-26 parts of a pigment, 10-18 parts of functional filler, 0.2-0.7 parts of a rheological agent, 0.1-0.5 parts of a wetting dispersant, 0.2-0.6 parts of a substrate wetting agent, 0.2-0.5 parts of an anti-settling agent, 0.2-0.6 parts of an antifoaming agent, 0.2-0.6 parts of a thickener, 0.1-0.5 parts of a leveling agent, 2-5 parts of a flame retardant, 15-20 parts of a curing agent and 50-100 parts of deionized water. The low-carbon waterborne coating has the advantages of short drying time, high adhesion, high elasticity, medium resistance, bending resistance, flame retardance, high-and-low-temperature resistance, no adverse effect on the basic material and the like, and is an environment-friendly low-carbon waterborne coating with excellent combination properties.

Description

technical field [0001] The invention relates to the technical field of preparation of environmentally friendly coatings, in particular to a low-carbon water-based coating and a preparation method thereof. Background technique [0002] With the development of the synthetic rubber industry, rubber products have expanded from natural rubber to various synthetic rubbers such as chloroprene rubber, nitrile rubber, butyl rubber, and ethylene-propylene rubber, and the application fields have also continued to expand. Since the rubber itself has quite good anti-corrosion properties, and can meet the general purpose requirements through filling and coloring, the rubber coating and its coating technology have not attracted enough attention for quite a period of time. [0003] With the development of the economy, people have higher and higher requirements for the performance, protection and decoration of rubber products. Coatings can not only endow rubber products with excellent prote...
