Abstract

The invention discloses a preparation method for a multifunctional color masterbatch. The preparation method comprises the following steps: S1, pretreating a high-temperature-resistant organic pigment; S2, mixing polyethylene glycol with polypropylene and adding the high-temperature-resistant organic pigment to obtain a mixture B; S3, subjecting epoxy resin to heating and fusing in a kneader and adding the mixture B to obtain a mixed material C; S4, adding UV-9, UV-234 and an anti-oxidant into the mixed material C to obtain a mixed material D; S5, cutting off metal silver fibers and rock woolfibers, carrying out mixing to obtain a fiber blend and adding the fiber blend into the mixed material D so as to obtain a rubber compound for the color masterbatch; and S6, conveying the rubber compound for the color masterbatch into a screw rod extruder and successively carrying out extrusion molding, programmed drying, cooling and size stablization so as to obtain the multifunctional color masterbatch. According to the preparation method in the invention, the varieties and ratio of raw materials are reasonable; mixing effect of the raw materials are good; the method is stable in process; and the prepared color masterbatch has excellent resistance to temperature, wear and the sun, good stability, antioxidation performance and ultraviolet resistance.

Description

technical field [0001] The invention relates to the technical field of color masterbatch development, in particular to a preparation method of multifunctional color masterbatch. Background technique [0002] The full name of color masterbatch is color masterbatch, also called color seed, it is a new type of special colorant for polymer materials, also known as pigment preparation, which is mainly used in plastics. The color masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading super-normal pigments in the resin. It can be called a pigment concentrate, so its coloring power is higher than that of the pigment itself. When processing, a small amount of color masterbatch and uncolored resin is mixed to achieve the colored resin or product with the designed pigment concentration. The currently produced color masterbatch has a single function and is usually only used for coloring, and its stability is ...
