Problems solved by technology

On the surface of plastic parts such as automobiles and motorcycles, such as automotive interior parts, bumpers, and motorcycle plastic parts, because of the special plastics, it is mostly polypropylene (PP), polyethylene (PE) or a copolymer of the two. Polyolefin is characterized by high crystallinity, strong solvent resistance, low surface polarity and low surface energy, and poor adhesion of traditional coatings
[0005] In addition, the surface of injection molded parts such as automobile interior decoration and motorcycle injection molded parts has a semi-gloss or matte effect. The fineness of the paint film and the arrangement of the matt powder are relatively high, but after the traditional aerosol paint is repaired, the surface of the paint film is delicate and the arrangement of the matt powder is poor, and the difference with the substrate is obvious, the repair marks are easy to be detected, and the aesthetics are not enough

Abstract

The aerosol paint is prepared from the following components in parts by weight: 25 to 35 parts of modified acrylic resin, 1 to 2 parts of a post-crosslinking agent, 7 to 13 parts of a coloring agent, 0.3 to 1.2 parts of a dispersing agent, 0.1 to 0.5 part of a flatting agent, 5 to 9 parts of wear-resistant filler, 0.5 to 1.5 parts of a reinforcing agent, 7 to 15 parts of an environment-friendly solvent and 35 to 45 parts of a propellant. The aerosol paint adopting the technical scheme has the following advantages: the aerosol paint has excellent adhesive force on the surfaces of plastic and polyolefin plastic; the paint has good compatibility with propellants, is excellent in spraying atomization, convenient to construct, smooth and fine in paint film and perfect in workpiece repairing effect, and repairing traces are difficult to perceive by naked eyes; a paint film is high in hardness, quick to dry and excellent in wear resistance. The invention also discloses a preparation method of the aerosol paint.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an aerosol paint and a preparation method thereof. [0002] technical background [0003] Aerosol paint is more and more popular among the public because of its easy portability, self-contained pressure, good construction atomization, and easy operation. It is widely used in the spraying of various substrates such as metal, wood, ABS, and PVC. [0004] Self-spraying paint is widely used in the field of vehicle repair, and is mostly used for paint repair, color change, vehicle identification number and other purposes. On the surface of plastic parts such as automobiles and motorcycles, such as automobile interior parts, bumpers, and motorcycle plastic parts, because of their special plastics, most of them are polypropylene (PP), polyethylene (PE) or a copolymer of the two. However, polyolefins are characterized by high crystallinity, strong solvent resistance, low surface polarity and su...
