Abstract

The invention discloses colorful rock slice coating with graphite grafted polyaniline and with electromagnetic shielding effect. Graphite oxide is modified by utilizing a silane coupling agent KH550, amino is introduced on the surface of the graphite oxide, polyaniline is grafted to prepared polyaniline grafted modified graphite, and the polyaniline grafted modified graphite is added into the coating, so the mechanical strength and the wear resistance of a coating film are enhanced and the electrical conductivity of the coating film is improved ; the colorful rock slice coating has the appearance of granite, has excellent coating film adhesive force, firmness, wear resistance, high compactness, high storage stability, high electrical conductivity and excellent electromagnetic shielding property, can resist electromagnetic radiation, is applied to an indoor wall surface, is safe, non-toxic, beautiful and elegant, and is harmless to a human body.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a colorful rock flake coating with graphite-grafted polyaniline and an electromagnetic shielding effect. Background technique [0002] Water-based composite rock flake imitation granite paint is also called rock flake paint and granite stone paint. It is a new type of pure water-based sand wall-shaped architectural paint that does not contain any solvent-based substances. It is rich in the style of granite, the connotation of granite, the nobility of granite, and the grade of granite. , is an upgraded variety of traditional natural stone paint. With the wide application of new coatings in the construction market, the research on the formulation of composite rock slices in architectural coatings has attracted more and more attention from researchers. Water-based composite rock flake imitation granite paint is prepared from high-quality synthetic resin emulsion, colored composite...
