Abstract

The invention belongs to the technical field of matting antistatic materials, and provides a matting antistatic material for a CPP cast film and a preparation method thereof.The matting antistatic material for the CPP cast film is prepared from, by weight, 30-60 parts of PP resin, 20-70 parts of matting modifier, 5-20 parts of superfine graphite, 0.2-2 parts of antioxidant, 0.5-5 parts of coupling agent and 0.2-2 parts of dispersing lubricant; wherein the matting modifier is at least one of light calcium carbonate and superfine silicon dioxide. According to the matting antistatic material for the CPP cast film, the matting modifier and the superfine graphite are added into the PP resin, and other auxiliaries are matched, so that the matting performance and the antistatic performance of the matting antistatic material are effectively improved.

Description

technical field [0001] The invention relates to the technical field of matting and antistatic materials, in particular to a matting and antistatic material for CPP cast film and a preparation method thereof. Background technique [0002] Polypropylene film, referred to as PP film, has the characteristics of light weight, moisture resistance, high mechanical strength, good dimensional stability, non-toxic, odorless, etc. Therefore, it is widely used in packaging materials for cigarettes, food and agricultural by-products. PP film is mainly divided into three categories: CPP cast film, BOPP film and IPP film. Among them, the CPP cast film is a non-stretched, non-oriented flat extrusion film produced by melt casting and quenching. There are two ways of single-layer casting and multi-layer co-extrusion casting; Cast film has the characteristics of fast production speed, high output, transparency and uniform thickness of the film. Therefore, CPP cast film is the most widely used...
