Problems solved by technology

[0002] The material of automobile bumper is basically made of PP plastic (polypropylene). Due to the high surface density of PP plastic, the coating produced by general thermoplastic acrylic resin cannot be well pasted on the surface of PP plastic. When dry, the layer is like a mask, and the whole sheet will be torn off with a light tear, so a special adhesion promoter is needed to solve these problems

Embodiment 1

[0018] (1) Mix and stir 70 kg of xylene, 10 kg of butyl acetate, and 5 kg of cyclohexanone until uniformly dispersed to obtain the raw materials of Group A;

[0019] (2) Mix 10 kg of chlorinated acrylic resin and 40% of Group A raw materials, stir until evenly dispersed, and obtain Group B raw materials;

[0020] (3) Mix and stir 5 kg of maleic anhydride resin and 35% of Group A raw materials, while raising the temperature to 60°C for 45 minutes to obtain Group C raw materials;

[0021] (4) In the remaining 25% of the raw materials of group A, add the raw materials of group B and group C in sequence, stir during the addition process, and adjust the temperature to 45°C for 30 minutes to obtain a golden yellow with A certain viscous liquid, that is, the finished product 1.

Embodiment 2

[0023] (1) Mix and stir 65 kg of xylene, 12 kg of butyl acetate, and 6 kg of cyclohexanone until uniformly dispersed to obtain the raw materials of Group A;

Abstract

The invention provides an adhesion promoter and a preparation method thereof. The adhesion promoter comprises the following components in percentage by weight: 65-75% of organic solvent, 8-12% of butyl acetate, 4-6% of cyclohexanone, 8-12% of chlorinated acrylic acid resin and 4-6% of maleic anhydride resin. The adhesion promoter according to the components and percentage can change the surface density of PP (polypropylene) plastics, and can enable the thermoplastic acrylic resin paint to be firmly adsorbed onto the PP plastic surface and not to shed easily.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an adhesion promoter and a preparation method thereof. Background technique [0002] The material of automobile bumpers is basically made of PP plastic (polypropylene). Due to the high surface density of PP plastic, the paint produced by general thermoplastic acrylic resin cannot be well pasted on the surface of PP plastic. When dry, the layer is like a mask, and the whole sheet will be torn off with a light tear. Therefore, a special adhesion promoter is needed to solve these problems. Contents of the invention [0003] The invention provides an adhesion promoter and a preparation method thereof, which can change the surface density of PP plastics and can be strongly adsorbed on the surface of PP plastics. [0004] The technical scheme of the present invention is achieved in that a kind of adhesion promoter and preparation method thereof, comprise each component of following percentag...
