Problems solved by technology

"The waterproof performance of the paint currently used is not good. It has a certain degree of waterproofness in the initial use process, but after a long time, it will react with the moisture in the air, resulting in dampness, which is not conducive to waterproofing, and will make the paint from the wall. body or objects, which affects the use, and the current coatings are all single-purpose. In some special places or objects, non-magnetic coating layers or anti-magnetic coating layers are required.

Abstract

The invention discloses antimagnetic coating comprising the following components in parts by weight: 50-100 parts of a prepolymer, 20-40 parts of inert resin, 50-70 parts of a monomer, 6-12 parts of aphotoinitiator, 2-8 parts of a coupling agent, 4-8 parts of an emulsifier, and 4-8 parts of a carbon-silicon mixture. Compared with conventional coating, the antimagnetic coating disclosed in the invention has better waterproof performance, is green, and can effectively insulate water to avoid the combination with moisture in air.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an antimagnetic coating. Background technique [0002] Coatings, traditionally called paints in China, are coatings on the surface of objects to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion. It is a viscous liquid prepared with organic solvent or water with or without adding pigments, fillers, and corresponding additives. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it like this: "Painting is a kind of material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, certain strength, and continuous coating. Solid film. The film formed in this way is commonly called coating film, also known as paint film or coating. "The waterproof performance of the coating used at present is no...
