Problems solved by technology

In the technical solution announced by the above patent, the alkaline earth metal sulfide and other components used are mainly used in the fields of architectural decoration, fire safety and other fields. The patented coating product has good adhesion to concrete and steel frame structures, but it is used in plastic materials When it is used, the adhesion is not good, and the powder with large particle size such as alkaline earth is used in the formula, which will make the appearance of the paint rough after brushing, which is not suitable for the field of automotive interior decoration.

Abstract

The invention relates to an automotive interior energy-storage fluorescent paint and a preparation method thereof. The fluorescent paint comprises, by weight, 40-50 parts of thermoplastic acrylic resin, 5-15 parts of chlorinated polypropylene resin, 10-20 parts of fluorescent powder, 1-5 parts of abrasive powder, 0.1-0.5 parts of anti-sediment agent, 0.2-0.5 part of flatting agent, 0.5-1.5 parts of antioxidant and 15-25 parts of mixed solvent. The preparation method includes sequentially adding mixed solvent, thermoplastic acrylic resin, chlorinated polypropylene resin, anti-sediment agent and abrasive powder to an agitator vessel, agitating and mixing fully to obtain a mixture, transferring the mixture to a horizontal type grinder, grinding the mixture fully until fineness thereof is not larger than 20 micrometers, and then transferring the ground mixture to the agitator vessel, adding flatting agent, antioxidant and florescent powder according to part by weight and stirring and then mixing completely so as to obtain the automotive interior energy-storage fluorescent paint. Compared with the prior art, the fluorescent paint has the advantages of high adhesion, high light intensity, long lighting time, high stability, wear resistance and the like, can emit light at night when applied to automotive interiors, and is energy-saving, environmental friendly, convenient and practical.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a fluorescent coating and a preparation method thereof, in particular to an energy-storing fluorescent coating for automobile interior decoration and a preparation method thereof. Background technique [0002] With the popularization of automobiles, traveling by car has become the first choice of more and more people. With the continuous development of people's individual needs for automobiles, the decorative requirements for automobile interior parts are also getting higher and higher. At present, the plastics widely used in automobile interior parts are mainly thermoplastic resins, such as ABS copolymers. , polypropylene, polyurethane, polyvinyl chloride, polyethylene, etc. However, when these interior parts are molded and processed, they will have defects such as uneven color, monotonous color, mottled defects, etc., and are prone to aging, brittleness, scratches, stains, stat...
