Transparent film mother material and its preparation process

Abstract

A mother material for transparent film is prepared proportionally from inorganic powder, composite resin as carrier, lubricant, composite coupling agent, and disperser through fusing or powdering the composite resin, coating the surface of inorganic particles by disperser, composite coupling agent, thermoplastic elastomer and composite resin sequentially in high-speed mixer, plasticizing, granualting, hot cutting and cooling. It has high mechanical performance, dispersity and optical property.

Description

1. Technical field:

[0001] The invention relates to a masterbatch and a preparation method thereof, in particular to a transparent film masterbatch and a preparation method thereof. 2. Background technology:

[0002] In China's plastic processing industry, the plastic packaging industry and the agricultural plastic industry are the industries with the largest output. Among them, various and varied plastic films such as packaging films, agricultural land films, and greenhouse films, whether blow-molded or tape-cast, and extended products of films, such as composite films and geocomposites, use a large amount of resin , mainly high-density polyethylene, low-density polyethylene and linear low-density polyethylene.

[0003] In the context of rising oil prices, the price of resin has soared, but the price of products cannot be increased, which makes plastic processing enterprises fall into a very difficult situation. How to face the price increase of plastic raw materials, man...
