Abstract

The invention discloses a formula for blending modification of PE and EVOH. Each 100 parts of HDPE resin is cooperatively used with 13 to 17 parts of EVOH resin, 3 to 6 parts of a PE-g-MAH compatilizer and 0.2 to 0.3 part of a HSt auxiliary agent. The formula provided by the invention can substantially improve barrier properties.

Description

technical field [0001] The invention relates to a polymer composite material formulation, in particular to a PE blending formulation. Background technique [0002] PE blend materials have high strength and toughness, but poor barrier properties. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a PE and EVOH blend modification formula that can significantly improve the barrier performance. [0004] The present invention achieves technical goals through the following technical solutions. [0005] PE, EVOH blending modification formula, the improvement is: for every 100 parts of HDPE resin, equipped with 13-17 parts of EVOH resin, 3-6 parts of PE-g-MAH compatibilizer, 0.2-0.3 parts of HSt additive . [0006] The further improvement is: for every 100 parts of HDPE resin, 14-15 parts of EVOH resin, 4-5 parts of PE-g-MAH compatibilizer, and 0.2-0.25 parts of HSt additive are prepared. [0007] Compared with the pr...
