[0003] Polypropylene plastic woven bag packaging is easy to tear during use and handling, and it is easy to break when encountering hard objects. Moreover, plastic woven bag packaging is stacked outdoors, and after being exposed to sunlight and absorbing ultraviolet rays, it is easy to cause polymer oxidation and degradation. The mechanical properties of plastic woven bag products are reduced and the service life is shortened

Abstract
The invention relates to an anti-tearing and anti-aging modified master batch. A formula of the anti-tearing and anti-aging modified master batch comprises the following ingredients in parts by weight: 15 to 25 parts of carrier resin, 70 to 80 parts of filling materials, 0.5 to 1 part of coupling agents, 2 to 4 parts of dispersing agents, 0.2 to 1 part of light stabilizers, 0.2 to 0.5 part of antioxidants and 0.2 to 1 part of graphene. The nanometer calcium carbonate or talc powder is used as filling materials; meanwhile, polyethylene, graphene, the light stabilizing agents and the antioxidants are added, so that the product has high anti-tearing performance, excellent UV-resistance effect and long service life; the heat degradation in the processing process can be effectively inhibited; the heat oxidization aging and light aging in the use process can be relieved; the anti-tearing and anti-aging modified master batch is applicable to plastic products such as polypropylene flexible freight bags, weaving bags and films with the anti-aging requirements.
Description
technical field [0001] The invention relates to the field of plastic products, in particular to a tear-resistant and anti-aging modified masterbatch. Background technique [0002] In the production process of plastic products such as polypropylene container bags, woven bags and films, adding a certain proportion (generally up to 10 to 30 parts) of filler modified masterbatch can not only greatly reduce the product cost, but also can Improve certain mechanical properties of plastic products to a certain extent, such as rigidity, toughness, wear resistance, etc. [0003] Polypropylene plastic woven bag packaging is easy to tear during use and handling, and it is easy to break when encountering hard objects. Moreover, plastic woven bag packaging is stacked outdoors, and after being exposed to sunlight and absorbing ultraviolet rays, it is easy to cause polymer oxidation and degradation. As a result, the mechanical properties of plastic woven bag products are reduced and the se...
