Problems solved by technology

But the problem is that this kind of plastic primer cannot be applied to plastic parts of different materials at the same time, but it is made for plastic parts of a certain material, so it adds a lot of inconvenience to the accessories when painting
In addition, the existing commercially available plastic primer products have weak adhesion, poor cooking resistance and short service life

Embodiment 1

[0026] A silicone modified acrylic resin primer for plastic parts. The primer is composed of silicone modified acrylic resin, hexamethanol etherified amino resin, pigments, additives and solvents. The weight percentage of each component is:

[0027]

[0028] When preparing, weigh each raw material according to the proportion, first add the silicone modified acrylic resin to the dispersant and stir evenly, add the pigment and solvent while stirring, disperse and grind until the fineness is less than 20 microns, and add the flow after cooling. For leveling agent, just stir evenly.

[0029] The properties of the product prepared in this embodiment are as follows:

Abstract

The invention discloses an organic silicon modified acrylic resin primer of plastic articles. The primer comprises the following constituents by weight percent: 45-55% of organic silicon modified acrylic resin, 10-15% of hexamethyl alcohol etherified amino resin, 20-25% of pigment, 6-15% of accessory ingredient and the balance of solvent. The primer has better compatibility to the plastic articles made of different materials, so that waste and trouble caused by frequent change of paint during construction can be reduced by utilization of such product, and the working efficiency is improved greatly. The product in the invention has better boiling resistance and thermal cycling resistance.

Description

Technical field [0001] The invention belongs to the technical field of chemical engineering, and relates to a primer, in particular to a silicone modified acrylic resin primer for plastic parts. Background technique [0002] Plastic coatings are similar to those used for other metal parts, and are also divided into primers, base paints, varnishes or top coats. The primer can be directly coated on the surface of the surface-treated plastic substrate to cover the surface of the plastic parts. Flow marks and defects. With the rapid development of the automobile and shipbuilding industry, the weight of automobiles and ships has a trend of lightening. Therefore, plastic parts of various materials are increasingly used in vehicles such as automobiles. [0003] In today's plastic parts coating manufacturing industry, the main resin in its formulation is mostly made of polypropylene resin and other raw materials, processed according to conventional production techniques. For example, the...
