Functional high-concentration chromoplastid and manufacturing method thereof

Abstract

The invention discloses a functional high-concentration chromoplastid and a manufacturing method thereof. The functional high-concentration chromoplastid comprises the following components by mass: 55-65 percent of a pigment, 30-40 percent of carrier resin, 2-4 percent of a dispersant, and 1.5-2.5 percent of an additive. The manufacturing method comprises the following steps: mixing, refining, extruding and granulating, drying, conducting a solid-phase reaction, and detecting and packing. The chromoplastid has the advantages that chemical stability and color stability of the pigment are remained, the pigment has better dispersibility in plastics, the health of an operator is protected, the process is simple, the color turning is easy, the environment is clean, vessels are not stained, and time and raw materials are saved.

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] The main function of the colored particles is to color the plastic or add other functional plastic semi-finished products, but the products currently on the market may not be directly used for production, and other functional raw materials must be mixed in the process. The performance of the product is still unstable, and sometimes the coloring may not meet the requirements, and the function may not meet the product performance requirements; the product cost is also very high, which greatly restricts the development of the enterprise. [0003] Colored granules are mainly used on plastics. Since the pigments are in direct contact with the air during storage and use, moisture absorption, oxidation, and agglomeration will occur. When used directly, color spots, dark hues, and color wi...

[0003] Colored granules are mainly used on plastics. Since the pigments are in direct contact with the air during storage and use, moisture absorption, oxidation, and agglomeration will occur. When used directly, color spots, dark hues, and color will appear on the surface of plastic products. Easy to degrade and cause dust when mixed, affecting the health of operators
