Abstract

The invention discloses an antioxidative plastic woven bag. According to the invention, polypropylene is used as a base material, the varieties and formula of master batch raw materials are optimized, production technology is improved, and a composite anti-oxidant containing bitter apricot kernel oil (rich in vitamin E) is scientifically compounded; the antioxidative plastic woven bag employs modified nano-carbon capable of substantially improving the high-temperature resistance, contraction resistance, relative tensile load, strength, toughness and elastic modulus of the plastic woven bag; the antioxidative plastic woven bag also employs Cerasus humilis fiber capable of substantially improving the shock resistance of the plastic woven bag and reducing production cost and easy to biodegrade, a polyethylene/winter rye peptide compound capable of greatly improving the low-temperature resistance of the plastic woven bag, and the bitter apricot kernel oil capable of effectively enhancing the lubricity and inoxidizability of the plastic woven bag; and preparation raw materials for the antioxidative plastic woven bag have a long oxidation induction period, and the oxidation induction time is decreased by 58.33% compared with a commercially-available antioxidative modified polypropylene material. The prepared antioxidative plastic woven bag has substantial antioxidation performance and anti-aging performance, good weatherability, good environmental suitability and long service life.

Description

technical field [0001] The invention relates to a plastic woven bag, in particular to an anti-oxidation plastic woven bag and a preparation method thereof. Background technique [0002] Plastic woven bags are made of polypropylene (PP) and polyethylene (PE) resins as the main raw materials, adding a small amount of auxiliary materials, mixing them and melting them through an extruder, extruding plastic films and cutting them into filaments, which are processed at a temperature lower than the melting temperature of the resins Stretching, making high-strength, low-elongation flat yarn through molecular orientation and heat setting, and then winding, weaving, cutting, and sewing to make plastic woven bags. Plastic woven bags are divided into TA type, A type, B type and C type according to the loading quality range, TA type is allowed to load 10~20kg, A type is allowed to load 21~30kg, B type is allowed to load 31~50kg , Type C is allowed to load 51 ~ 60kg. Plastic woven bags ...
