Abstract

The invention discloses a high-strength moisture-resistant oxygen-resistant heat-resistant high-density polyethylene film. Raw materials in parts by weight of the film include: 80-120 parts of high density polyethylene, 30-50 parts of EVA resin, 3-6 parts of ethylene-vinyl acetate copolymer, 4-8 parts of tertiary butanol hydrogen peroxide, 2-5 parts of zinc stearate, 3-9 parts of alumina, 8-12 parts of organic montmorillonite, 5-15 parts of bentonite, 4-8 parts of kaolin, 6-9 parts of diatomite and 4-9 parts of a silane coupling agent KH-550. The invention also provides a preparation method of the high-strength moisture-resistant oxygen-resistant heat-resistant high-density polyethylene film. The prepared high-density polyethylene film has high strength and excellent moisture-resistant, oxygen-resistant and heat resistant properties.

Description

technical field [0001] The invention relates to the technical field of polyethylene films, in particular to a high-strength moisture-proof, oxygen-proof and heat-resistant high-density polyethylene film and a preparation method thereof. Background technique [0002] High-density polyethylene is referred to as "HDPE" for short, also known as low-pressure polyethylene, which is a translucent shape with high crystallinity and a certain degree of non-polar surface. PE has excellent resistance to most domestic and industrial chemicals. [0003] HDPE is a highly crystalline, non-polar thermoplastic resin. High-density polyethylene is a white powder granular product, non-toxic, tasteless, with a density of 0.940-0.976g / cm 3 Within the range; the crystallinity is 80-90%, the softening point is 125-135°C, and the service temperature can reach 100°C; the melting temperature is 120-160°C. For materials with larger molecules, the melting temperature range is recommended to be between ...
