Abstract

The invention relates to the technical field of a high polymer material, and concretely discloses a smooth opening master batch and a preparation method thereof. The smooth opening master batch is prepared from the following raw material ingredients in parts by weight: 80 to 100 parts of PE resin, 30 to 50 parts of slipping agents,30 to 50 parts of opening agents, 20 to 30 parts of maleic anhydride grafting compatibilizer and 1 to 3 parts of antioxidants. The master batch is the smooth opening master batch with the fire-new composition; the organic opening agents obtained through fire-new preparation are added into the smooth opening master batch; the opening performance and the lubricating performance are good.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a smooth opening masterbatch and a preparation method thereof. Background technique [0002] PE resin is referred to as PE, also known as polyethylene, which is divided into high-density polyethylene HDPE, medium-density polyethylene MDPE, low-density polyethylene LDPE and linear low-density polyethylene LLDPE. It is one of the most commonly used polymer materials in daily life. . For example, high-density polyethylene is mainly used to manufacture various injection molding, blow molding and extrusion molding products. Low-density polyethylene (LDPE) is widely used as packaging materials for various food, clothing, medicine, chemical fertilizers, industrial products, and agricultural films. It can also be processed into composite films by extrusion for packaging heavy objects. [0003] However, the existing polyethylene products are prone to sticking and not easy to o...
