Problems solved by technology

[0002] At present, among the industrial coatings used in the market, the ordinary alkyd paint will become soft when the weather gets hot, and its weather resistance is relatively poor. If there is any remaining agent after use, the remaining part will be cured soon and cannot be used. The waste is large and the price is high. Thermoplastic acrylic paint has strong weather resistance and does not need to add curing agent when using it. Therefore, thermoplastic acrylic paint It has been widely used, but the adhesion of ordinary thermoplastic acrylic paint is relatively poor, and it is easy to fall off

Abstract

The present invention discloses one kind of thermoplastic acrylic paint comprising thermoplastic acrylate resin, pigment, assistant and solvent. The process of producing the thermoplastic acrylic paint includes the following steps: mixing and dispersing thermoplastic acrylate resin, pigment and dispersant in certain weight proportion in a high speed dispersing machine; grinding the mixture in a sand mill to reach required fineness; adding defoaming agent, leveling agent and solvent and stirring in the high speed dispersing machine to obtain the thermoplastic acrylic paint. Compared with common paint, the thermoplastic acrylic paint has the advantages of use convenience, high weather resistance, low cost and high adhesion.

Description

technical field [0001] The present invention relates to a paint, in particular to a thermoplastic acrylic paint. Background technique [0002] At present, among the industrial coatings used in the market, the ordinary alkyd paint will become soft when the weather gets hot, and its weather resistance is relatively poor. If there is any remaining agent after use, the remaining part will be cured soon and cannot be used. The waste is large and the price is high. Thermoplastic acrylic paint has strong weather resistance and does not need to add curing agent when using it. Therefore, thermoplastic acrylic paint It has been widely used, but the adhesion of ordinary thermoplastic acrylic paint is relatively poor, and it is easy to fall off. Contents of the invention [0003] The object of the present invention is to provide a thermoplastic acrylic paint which is easy to use, has strong weather resistance, low cost and strong adhesion. [0004] To achieve the above object, the p...
