Abstract

The invention discloses a polypropylene jade imitating color master batch and a preparation method thereof. The color master batch of the invention consists of an A color master batch and a B color master batch, the weight percentage of which are respectively 40 percent to 60 percent and 40 percent to 60 percent. The A color master batch consists of the following components by weight percentage: 55 percent to 90 percent of carrier, 5 percent to 15 percent of compatibilizer, 0 percent to 5 percent of toner, 0 percent to 15 percent of filler, 0 percent to 5 percent of dispersant and 0 percent to 5 percent of processing additive; the B color master batch is a traditional color master batch and consists of the following components by weight percentage: 80 percent to 97 percent of carrier, 0.01 percent to 10 percent of toner, 1 percent to 5 percent of dispersant and 1 percent to 5 percent of processing additive. The jade imitating color master batch provided by the invention is applied to the coloring of polypropylene products, can be molded in a one-time injection manner and can generate the fluxing banding with the effect of natural jade, thus solving the problem of secondary processing of plastic products. Meanwhile, the preparation method of the polypropylene jade imitating color master batch is simple and practical and can bring considerable economic benefits.

Description

technical field [0001] The invention relates to the technical field of plastic coloring, in particular to a polypropylene imitation jade color masterbatch and a preparation method thereof. Background technique [0002] Polypropylene (PP) resin is a thermoplastic developed in the 1960s. Its production process can be divided into five categories: solution method, slurry method, bulk method, gas phase method and bulk method-gas phase method combined process according to the polymerization type. Because of its small specific gravity, good mechanical properties such as tensile strength, impact strength and hardness, almost no water absorption, non-toxic and tasteless, it is widely used in various fields of production and life. [0003] In the prior art, there are three methods of coloring polypropylene materials: toner coloring, dyeing granulation, and masterbatch coloring. Toner coloring is easy to produce color spots, and the color difference is not easy to control, and it has ...
