Abstract

The invention discloses a heat-aging resistance modified polyvinyl chloride woven bag which is prepared from a modified polyvinyl chloride composite material. Raw materials of the modified polyvinyl chloride composite material comprise the following components: polyvinyl chloride, thermoplastic polyurethane, an acrylonitrile-butadiene-styrol copolymer, a calcium stearate-zine stearate compound, bis(2-hydroxyethyl)amino(trishydroxymethyl)methane, dibutyltin dilaurate, barium sulfate, light calcium carbonate, a rare-earth coupling agent, decabromodiphenylethane, antimonony oxide, eleaostearic acid, isocyanate, 1,2-cyclohexane dicarboxylic acid di-isononyl ester and an antioxidant 1010. The heat-aging resistance modified polyvinyl chloride woven bag brought forward in the invention has good thermal stability, excellent thermal aging resistance and shock resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a heat-aging-resistant modified polyvinyl chloride woven bag. Background technique [0002] Plastic woven bag is a kind of packaging material obtained by using plastic raw materials, extruding film, cutting, and unidirectional stretching into flat wire, and weaving warp and weft. Since my country developed flat wire woven bag in 1966, the product has developed rapidly. It has formed a series of products with various colors and varieties and complete specifications and sizes, which have been widely used in agricultural product packaging, construction packaging, chemical product packaging, food packaging and other fields. [0003] Polyvinyl chloride is a general-purpose plastic with low price, corrosion resistance and low energy consumption. It is the second largest plastic variety next to polyethylene in the world. Its domestic output ranks first among plastics. It has excellent e...
