Coating additive and preparation method thereof

Abstract

The invention discloses a coating additive and a preparation method thereof. The coating additive comprises the following raw material formula components in parts by mass: 10-15 parts of linoleic soap, 5-10 parts of abietic soap, 5-10 parts of a flexibilizer, 2-5 parts of activated calcium carbonate particles, 15-20 parts of polymerized vegetable oil, 1-5 parts of white carbon black, 1-5 parts ofmetallic soap, 15-25 parts of methyl silicone oil, 3-5 parts of a fluorine-containing surfactant, 15-20 parts of polyacrylate, 2-10 parts of nano titanium oxide, 1-2 parts of an ultraviolet absorber and 2-10 parts of distilled water. By adding the non-ionic fluorocarbon surfactant, a film can form a smooth coating surface, the attractive effect is improved, and the practicability is high. By adding the metallic soap and the methyl silicone oil, sedimentation or floating of the coating is prevented, so that the mixed and proportioned coating can be effectively stored for a long time and convenient to use. By adding one or a mixture of salicylate and benzophenone, the anti-ultraviolet effect of the coating in the using process can be improved, the coating film is prevented from aging and falling off, and the service life of the coating film is prolonged.

Description

technical field [0001] The invention relates to a coating additive, in particular to a coating additive and a preparation method thereof, and belongs to the technical field of coating additive production. Background technique [0002] Coating additives, also known as paint auxiliary materials, are auxiliary materials for preparing coatings, which can improve the performance of coatings and promote the formation of coating films. There are many types, including driers, tougheners, emulsifiers, thickeners, pigment dispersants, defoamers, leveling agents, anti-skinning agents, matting agents, light stabilizers, anti-mold agents, antistatic agents (see plastic additives), etc., among which the most used are drier and toughening agent. At present, the research on coating additives focuses on the additives used in water-emulsion paints. [0003] There are some deficiencies in the use of coating additives. The mixing of coating additives and paint can improve the performance of t...

AI Technical Summary

Problems solved by technology

[0003] There are some deficiencies in the use of coating additives. The mixing of coating additives and paint can improve the performance of the coating, but the surface of the formed coating film is not smooth enough to prevent the coating from settling during long-term storage. , leading to the coating with a good mixing ratio cannot be stored effectively for a long time, and it is inconvenient to use. Therefore, we provide a coating additive and its preparation method
