Abstract

The invention discloses an engineering plastic formula and an injection molding color matching method thereof. The engineering plastic formula specifically comprises the following components in parts by weight: 35 parts to 95 parts of polymer powder, 0.1 part to 8 parts of a capacity-increasing pre-dispersing agent, 4 parts to 60 parts of polymer particles, and 0.2 part to 5 parts of a functional auxiliary agent and 0 to 20 parts of a powder filler. Through specific formula components, especially the addition of the compatibilization pre-dispersing agent, the injection molding sample preparation matching color are uniform and consistent, and the dispersion is good. According to the injection molding color matching method, accurate weighing and uniform mixing are carried out according to an injection molding color matching formula, then injection molding is carried out on a sample preparation color plate, and the fluctuation range of [delta]L / [delta]a / [delta]b is controlled within 0.5 during sample preparation; meanwhile, the total color difference [delta]E is smaller than 1, the color matching and sample preparation requirements are met; and meanwhile, operation is easy, and the color matching efficiency and accuracy are improved.

Description

Technical field[0001]The present invention relates to the field of plastic color matching, and more particularly to an engineering plastic injection molding solution and a method of injection molding.Background technique[0002]The application of polymer material polymers is increasingly widely used in many fields due to high-plasticity, high quality, high quality, and high-quality intensity. The rapid development of modified engineering plastics has made a lot of breakthroughs in plastic steel, such as applications in home appliance housings, electric tools, electronic components, motion tools, and automotive parts. As the appearance, color design is diversified, more demand, and consumers are increasingly higher, so the color matching technology of engineering plastics is also mature. The coloring process of engineering plastic materials contains the preliminary range coloring process and mass production process, and the pre-selection coloring process requires multiple pigment recip...
