What is the definition of white masterbatch?
The white masterbatch is a novel polymer composite coloring material which is prepared by a high proportion of colorants, carrier resins and various auxiliary agents. The colorant is a basic component of the masterbatch, and the content is generally between 20% and 80%.
The white masterbatch usually uses titanium dioxide, barium sulfate, zinc barium white, zinc sulfide, calcium carbonate and the like as a coloring agent, black masterbatch uses carbon black as a coloring agent, and the color masterbatch uses azo pigment, phthalocyanine pigment, quinacridine. Ketone pigments, iron oxide red, metal powders, pearl powders, and dyes are colorants.
Resin is a carrier of white masterbatch, which has the properties of softening by heat, cooling and hardening, and does not have the characteristics of chemical reaction. The resin is melt-sheared and the like to uniformly distribute the colorant therein. In order to ensure the compatibility of the carrier with the colored plastic, it is generally selected as the carrier of the colored plastic similar resin, which is advantageous for better dispersion of the colorant.
The dispersant is an auxiliary agent which promotes uniform dispersion of the colorant to the resin and no longer aggregates. Currently used dispersing agents are polyethylene low molecular wax, stearate, ethylene glycol and the like.
According to the application and performance requirements of the product, various other additives such as antistatic agent, antioxidant, brightener, light stabilizer, foaming agent, antibacterial agent, matting agent and resistance are also needed in the preparation process of the masterbatch. A variety of fuels, etc., to give plastic products a special function.
Jiangsu Hongmei Masterbatch Co., Ltd. is an early enterprise engaged in research, development, production, sales and service of plastic masterbatch. The products are mainly composed of three major systems: plastic masterbatch, functional masterbatch and modified materials. The plastic masterbatch includes white masterbatch, black masterbatch, color masterbatch, polypropylene chemical fiber masterbatch and other products. The functional masterbatch includes antistatic, anti-aging, flame retardant, smooth, anti-fog and other products. Used in plastic processing enterprises such as injection molding, extrusion, coating, casting, drawing, blow molding, spinning.
