Abstract
The invention discloses an automobile coating and a processing technology thereof. The automobile coating is composed of, by weight, 15-35 parts of wollastonite powder, 12-52 parts of polyacrylonitrile-based carbon fibers, 50-60 parts of polyester, 10-15 parts of a solidifying agent, 1-5 parts of a leveling agent, 0.2-1.0 part of a light stabilizer, 0.2-1.0 part of a defoaming agent, 125-155 partsof composite filling, and 52-115 parts of an improving agent. The improving agent comprises, by weight, 30-50 parts of mono-butyltin oxide, 10-15 parts of quaternary ammonium salt, 20-30 parts of fluorinated acrylic ester, 1-5 parts of rare earth elements and 1-5 parts of titanium dioxide. According to the automobile coating and the processing technology thereof, the preparing technology is simple, environmental protection is realized and no pollution exists during preparing, the prepared coating is environmentally friendly, free of toxin and harm to human bodies, high in chemical stability,corrosion resistance and abrasion resistance, and capable of passivating and slowly eroding a metal substrate, and has no environmental pollution, meanwhile, the preparation method is simple, and large-scale industrial production is easy.
Description
technical field [0001] The invention relates to the field of chemical materials, in particular to an automobile paint and a processing technology thereof. Background technique [0002] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object 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, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. [0003] However, there are certain disadvantages in the existing automobile coating and its processing technology, serious pollution problems exist in the production process, and the prepared paint has certain toxicity and is harmful to the human body. Therefore, we propose an automobile coating and its processing technology. craft. Contents of the invention [0004] The object of the present invention is t...
