Ultraviolet-resistant woven bag yarn

Abstract

The invention provides an ultraviolet-resistant woven bag yarn. The ultraviolet-resistant woven bag yarn contains the following components in parts by weight: 77-105 parts of low density polyethylene resin, 11-15 parts of polyester imide resin, 1-5 parts of an ultraviolet light absorber, 2-5 parts of sorbitol, 2-4 parts of dioctyl sebacate, 33-45 parts of filler and 2-7 parts of an aid, wherein the aid contains following components in parts by weight: 3-5 parts of a lubricating agent, 2-5 parts of a coupling agent, 1-2 parts of a stabilizer, 1-2 parts of a crosslinking agent and 1-3 parts of an antioxidant. The ultraviolet-resistant woven bag yarn has the beneficial effects that the constitution components and the proportion are unique, and meanwhile, a production method is simple and rapid; when the excellent ultraviolet resistance is guaranteed, the ultraviolet-resistant woven bag yarn further has excellent temperature resistance and weather resistance and is capable of remarkably maintaining each mechanical performance of a woven bag body and the ultraviolet resistance; and the components are easily available, and the ultraviolet-resistant woven bag yarn is relatively low in cost and suitable for being popularized in small and medium-sized enterprises.

Description

Technical field [0001] The invention belongs to the technical field of packaging and transportation, and specifically relates to an ultraviolet-resistant yarn for woven bags. Background technique [0002] Woven bag, also known as snakeskin bag, is a kind of plastic bag. It is used for packaging. Its raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. They are mainly used to store transportation items. Due to the limitation of storage environment, the existing When the woven bag is exposed to the outside sunlight for a long time, not only the color is easy to change, but the surface is also prone to air bubbles and swelling, and each woven bag thread also has cracking, which seriously affects its performance; [0003] Therefore, in order to solve the above problems, it is an urgent problem for those skilled in the art to develop an ultraviolet-resistant woven bag yarn. Summary of the invention [0004] In order to solve the above pr...
