Master batch special for flexible containers

Abstract

Belonging to the technical field of woven bag added auxiliary materials, the invention relates to a master batch special for flexible containers. The master batch is characterized by comprising the following raw materials by weight: 7-9 parts of polypropylene powder, 1.3-1.7 parts of POE, 0.8-1.3 parts of EVA, 100 parts of calcium carbonate, 0.017-0.023 part of an antioxidant 1010, 0.026-0.034 part of an anti-ultraviolet agent, 1.3-1.7 parts of an aluminic acid ester coupling agent, 1.3-1.7 parts of stearic acid, 1.3-1.7 parts of zinc stearate, and 6-9 parts of polyethylene wax. The sub-nanometer scale master batch special for flexible containers and woven bags provided by the invention can improve and enhance the technological performance and physical properties of woven bags, and also can be added by a maximum dosage under the premise, thus lowering the ingredient cost.

Description

technical field [0001] The invention discloses a special masterbatch for container bags, which belongs to the technical field of adding auxiliary materials to woven bags. Background technique [0002] With the increasing demand for container bags and woven bags in the domestic and international markets, the intensification of market competition and the sharp rise in raw material prices, plastic and woven enterprises across the country are generally considered to be in economic difficulties. [0003] Since container bags have higher technical requirements and stricter technical requirements than ordinary woven bags and woven fabrics, the selection of filler masterbatch puts forward higher requirements. The traditional filling masterbatch shows that the whiteness is not enough after adding; the dust is large during use, which will pollute the environment; at the same time, the dispersion of the existing masterbatch is not good, and it is easy to cause the machine head to block...
