AI Technical Summary

Problems solved by technology

However, metallic paint is expensive and rarely used on economical cars
Therefore, in daily life, it is often seen that the surface of economical car wheels fades, falls off, etc., which affects the appearance of such car wheels.
There are many researches on the application of wheel cover coatings at home and abroad, but there are not many reports on industrialization

Abstract

The invention discloses paint for automobile thermoplastic plastic parts as well as a preparation method and application of paint. The paint is prepared from the following components in parts by weight: 7 to 9 parts of aluminum powder, 8 to 10 parts of methylisobutylketone, 56 to 60 parts of elastic polyurethane resin, 7 to 9 parts of wax and 15 to 20 parts of diluting agent. The preparation method comprises the following steps: (1) stirring and uniformly mixing aluminum powder, methylisobutylketone and elastic polyurethane resin at a high speed; (2) adding the diluting agent, stirring at a middle speed, and dissolving solutes; and (3) adding the wax, stirring at a high speed until the wax is uniformly mixed with other components; and filtering to obtain the paint for the automobile thermoplastic plastic parts. The paint has the advantages of high adhesion, high ornamental performance, high corrosion resistance and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a coating for automotive thermoplastic parts and a preparation method and application thereof. Background technique [0002] In recent years, with the improvement of the overall purchasing power of bulk commodities such as cars, China's car manufacturing industry is in a state of blowout. High-performance thermoplastics for cars have been widely used in car interior parts because of their advantages in light weight, humanization, and energy saving. At present, the application in car exterior parts and functional structural parts is also being gradually promoted. [0003] At present, there are mainly two kinds of substrates for automotive wheel hub covers on the market: ABS+PC and PA66. PA66 and ABS+PC are thermoplastics. The advantages of thermoplastic resins are that they are easy to process and have high mechanical properties. The disadvantage is poor heat resistance and rig...
