Abstract

The invention discloses a high-gloss and puncture-resistant linear low-density polyethylene composite which comprises the following raw materials by mass percent: 99.50-99.66% of ethylene-butylene linear polyethylene copolymer, 0.25-0.35% of a nano EVA compound nucleator, 0.03-0.05% of a primary antioxidant and 0.06-0.10% of an auxiliary antioxidant. The invention further discloses a preparation method of the composite. The composite has the characteristics of excellent glossiness, higher puncture resistance and the like.

Description

technical field [0001] The invention relates to a linear low-density polyethylene composition, in particular to a high-gloss and puncture-resistant linear low-density polyethylene composition. Meanwhile, the invention also relates to a preparation method of the linear low density polyethylene composition. Background technique [0002] Linear low-density polyethylene (LLDPE for short) is non-toxic, tasteless, odorless milky white particles with a density of 0.918-0.935g / cm 3 . Compared with LDPE, LLDPE has a higher softening temperature and melting temperature, and has the advantages of high strength, good toughness, high rigidity, heat resistance, and cold resistance. Tear strength and other properties are widely used in the production of agricultural film, packaging film, composite film, etc. [0003] Since the molecular chain of LLDPE is dominated by short-chain branched chains and has a high degree of crystallinity, its transparency has been relatively low. In the act...
