Problems solved by technology

[0002] Polypropylene (PP) plastic is widely used in automobiles, electrical appliances, sports equipment, toys and other fields in industry. Since the surface of polypropylene does not carry electrostatic ions, it is a material that is difficult to adhere to. It is necessary to paint bright colors on it. Paint usually needs to be painted twice and baked at 70°C-80°C for more than 30 minutes to ensure its bright color and adhesion, so it is wasteful and costly in terms of labor and energy consumption

Abstract

The invention discloses a disposable PP (Propene Polymer) paint which comprises the following components: 25%-35% of chlorine modified thermoplastic acrylic resin, 5%-15% of hydroxy acrylic resin, 0.5%-1% of polymeric dispersant, 18%-25% of titanium dioxide, 3%-5% of xylene, 10%-20% of talcum powder, 1%-3% of modified polyester containing a special functional group, 5%-8% of methylbenzene, 5%-8% of methyl isobutyl ketone, 0.5%-1% of acrylic acid modified chlorinated polyolefine, 2%-4% of chlorinated copolyalkenamer, 1%-5% of propylene glycol monomethyl ether acetate (PMA), and 3%-6% of CAB cellulose. The disposable PP paint is excellent in water resistance, levelling property and adhesive force, can be directly coated on a PP material, and is safe and environmentally friendly, the performance is excellent, and the range of application is wide.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a disposable PP paint. Background technique [0002] Polypropylene (PP) plastic is widely used in automobiles, electrical appliances, sports equipment, toys and other fields in industry. Since the surface of polypropylene does not carry electrostatic ions, it is a material that is difficult to adhere to. It is necessary to paint bright colors on it. Paint usually needs to be painted twice and baked at 70°C-80°C for more than 30 minutes to ensure its bright color and adhesion, so the waste of labor and energy consumption is high and the cost is high. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a disposable PP paint. [0004] A disposable PP paint proposed by the present invention comprises the following components: chlorine-modified thermoplastic acrylic resin 25%-35%, hydroxyl acrylic...
