Problems solved by technology

[0002] At present, silver masterbatches and silver plastic products have appeared on the market, but generally speaking, the silver masterbatches sold on the market are aimed at a specific plastic base material, rather than a general type, and the silver masterbatches sold on the market The color masterbatch appears darker and grayer and flow marks appear during the manufacturing process of the product
The silver products appearing on the market are generally prepared directly by adding aluminum powder, pearl powder, and lubricants directly to the plastic base material. The product pearl powder prepared by this method cannot reach its due effect. The sanitation of the production environment has a certain impact

Abstract

The invention belongs to the technical field of chemistry, and relates to a metal color imitation silver color masterbatch preparation method. The silver color masterbatch comprises the following raw materials by weight: 60-75 parts of a base material, 3-5 parts of a lubricant, 3-5 parts of aluminum powder, and 10-15 parts of pearl powder. The preparation method has characteristics of simpleness, easy performing and easy cost control. The prepared silver color masterbatch can be uniformly dispersed in the plastic matrix so as to achieve the desired color effect. In addition, the silver color masterbatch prepared by the preparation method can not generate phenomena such as gray color, darkening color and flowing mark during the product preparation process so as to improve defects of products on the market.
