Problems solved by technology

[0002] At present, the manufacturing method of color masterbatch in domestic enterprises is the blending and granulation of resin powder and toner. The color masterbatch produced by this method has two shortcomings. Unevenness causes uneven dispersion, and it is easy to produce crystal points and have obvious color difference when producing plastic films; 2. When using powder resin to produce products, the color masterbatch cannot be blended evenly with powder resin, so it can only be used when producing products with powder resin The color masterbatch cannot be used in color powder; the color masterbatch of the present invention has a particle size of 1-3 microns, is uniformly dispersed, has no crystal points, has a small amount of use, has good gloss, no color difference, and has wide applicability

Abstract

The invention relates to a color masterbatch and a manufacturing method, specifically to pigmentation of a variety of plastics. The color masterbatch provided by the invention is composed of deionized water, polyvinyl butyral, ethanol, an antifoaming agent, a stabilizer, a plasticizer, a dispersant, polyethylene wax, ethylene oxide wax, a leveling agent, a coupling agent, plastic pigment powder, an anti-ultraviolet agent and an anti-ageing agent. The color masterbatch provided by the invention is prepared from a variety of raw materials in reasonable proportion, has excellent dispersion uniformity, smoothness, flexibility and low-temperature resistance, and significantly improves the quality of a product; the color masterbatch provided by the invention has two shapes of powder and granule, thereby meeting different addition requirements of powdered resins (like PVC) and granular resins (like PMMA) and achieving the effect of uniform pigmentation; and the color masterbatch provided by the invention is applicable to pigmentation of resins like PVC, ABS, PMMA, PS, polyurethane and epoxy resin.

Description
