Abstract

The invention provides a graphene composite coating. The graphene composite coating comprises the following components in parts by weight: 15-35 parts of modified graphene, 30-45 parts of acrylic ester emulsion, 2-4 parts of an ammonium polycarboxylate salt dispersing agent, 0.5-2 parts of a non-ion type wetting agent, 1-5 parts of calcium bentonite, 12-20 parts of a solvent and 1-3 parts of an addition agent, wherein the modified graphene is palladium doped graphene, the doped mole ratio of palladium atoms in the palladium doped graphene is 0.5-2%, and the acrylic ester emulsion is organic titanium modified acrylic ester emulsion.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a graphene composite coating and a preparation method thereof. Background technique [0002] Coatings refer to a class of liquid or solid materials that are coated on the surface of objects for protection, decoration or other special functions (insulation, rust prevention, mildew resistance, heat resistance, etc.). As an industrial product, paint is mainly used for decoration. [0003] The interior is the main living space of people, and the average time people spend working and living indoors is more than 10 hours a day. Therefore, the governance of the indoor environment has been paid more and more attention by people. Interior wall paint is an important part of building decoration materials. Its main function is to decorate and protect interior walls and create a beautiful and comfortable living environment. With the improvement of people's quality of life, people's requir...
