Antioxidant and ultravioresistant polypropylene woven bag raw material

Abstract

The invention discloses an antioxidant and ultravioresistant polypropylene woven bag raw material. The polypropylene woven bag raw material is added with anti-oxidant B215, anti-oxidant 1010, auxiliary anti-oxidant DLTP (dilauryl thiodipropionate) or DSTP (distearyl thiodipropionate), ultraviolet absorber UV531, light stabilizer GW-480, stearic acid, calcium stearate, calcium carbonate, mono-alkoxy titanate coupling agent YDH-101, and zinc stearate in powdered polypropylene, and then subjected to wiredrawing treatment in a drawing machine. Compared with the prior art, the raw material provided by the invention has advantages of good antioxidant and ultravioresistant properties, the raw material is particularly suitable for being used as woven bag raw materials, especially for being used as the raw material for manufacturing container bags.

Description

technical field [0001] The invention relates to an anti-oxidation and anti-ultraviolet polypropylene woven bag raw material. Background technique [0002] The container bag, also known as the ton bag, is a kind of container unit appliance, and it can be transported in a container unit with a crane or a forklift. [0003] As a flexible transport packaging container, container bags are suitable for bulk bulk and powdery materials, and are widely used in the transportation and packaging of food, grain, medicine, chemical industry, mineral products and other powdery, granular and lumpy items. It is widely used in the world as a packaging product for transportation and storage. [0004] The production process of container bags is generally based on polypropylene (PP) as the main raw material, which is extruded, drawn and formed, and finally finished by weaving and bag making. Container bags must meet four main points, namely safety, storage, usability, and airtightness. Therefo...

Problems solved by technology

[0005] However, since polypropylene is a material that is extremely prone to aging, the products made of polypropylene materials can only be used for a short period of time without additives. Deterioration may occur at each stage of the material, which will change the performance of the material, such as discoloration, molecular weight reduction, surface pulverization, etc., and more seriously, it will lead to a significant decline in the tensile strength, impact resistance and other performance parameters of the product, thus affecting the normal performance of the product. use
