Abstract

The invention provides a preparation method of a fireproof organic negative ion coating, which comprises the following steps: preparing negative ion particles: mixing tourmaline powder and water underthe condition of magnetic stirring to obtain tourmaline suspension; adding rare earth salts into the tourmaline suspension and mixing to obtain a mixed solution; adding a precipitant into the mixed solution to precipitate, drying the precipitate to obtain negative ion particles; preparation of fireproof particles: graphite is mixed with a mixture solution of hydrogen peroxide and nitric acid by stirring to obtain oxidized graphite; mixing the oxidized graphite with water, and then adding glacial acetic acid into the oxidized graphite dropwise and stirring to obtain fireproof particles; preparation of fireproof organic anion coating: mixing and grinding PVC and fire-retardant particles to obtain abrasive; preparing the fireproof organic negative ion coating by adding negative ion particlesand processing aid into the abrasive and stirring. The fireproof organic negative ion coating has the advantages of high performance-price ratio, effective removal of organic hazards and good fireproofing performance.

Description

technical field [0001] The invention relates to the field of organic anion coatings, in particular to a fireproof organic anion coating and a preparation method thereof. Background technique [0002] Organic polymer materials are the main components of latex paints. As film-forming substances, they can bond other components in the paint to form a whole, adhere to the surface of the coated base layer, and form a film through its easy drying and curing characteristics. Continuous and tough film. Especially as a synthetic material, its high cost performance and other factors make it widely used. [0003] However, when in use, since it is an organic polymer material, it is easy to emit organic poisonous and harmful substances. And coating is often used for interior decoration etc., therefore, above-mentioned organic coating can bring great harm to human health when actually using. [0004] At the same time, the vast majority of organic polymers are flammable and other propert...
