High-precision and pollution-free color masterbatch and pelleting process thereof

Abstract

The invention discloses a high-precision and pollution-free color masterbatch and a pelleting process thereof. The high-precision and pollution-free color masterbatch comprises the following components by mass: 88-93 percent of PET resin, 0.5-1 percent of titanium dioxide, 3.0-5.5 percent of chrome yellow, and 3.0-5.8 percent of ultramarine. The pelleting process comprises the following steps: melting, curing and sizing, and pelleting through cutting. The high-precision and pollution-free color masterbatc has relatively strong coloring power and covering power, is highly resistant to water, a solvent, heat, light and migration, bright in color, and high in dispersibility, the manufacturing process is simple, and no pollution is generated in the manufacturing process.

Description

technical field [0001] The invention discloses a colored granule, in particular to a functional high-concentration colored granule and a manufacturing method thereof. Background technique [0002] Plastics are widely used in all walks of life, from children's toys to instruments, from computer casings to auto parts, from toothbrushes and toothbrush hygiene products to aircraft parts, spaceships, and plastic products can be seen everywhere in our lives. Plastic resin is colorless and transparent, it is only a raw material, it will become a colorful assortment of plastic products, plastic coloring is an indispensable part of the plastic industry. [0003] Most of the coloring of plastics in modern plastic products manufacturing technology is to produce various plastic products by adding color masterbatches to plastic resins and then stirring, kneading, extruding and other methods. Masterbatch is a polymer made by uniformly loading super-normal pigments in resin. The first fu...

Problems solved by technology

[0004] However, the current heat resistance, light resistance and weather resistance of the current color masterbatch are intersected, making plastic products vulnerable to ultraviolet rays, and the aging speed of the plastic is faster, which affects the color and quality; the current color masterbatch is stirred during the manufacturing process. Dust will be generated. These particles are very small, and it is very harmful for people to inhale them. The diffusion of these particles to the turnover environment will also cause pollution.
