Problems solved by technology

Although ordinary TPE solves the halogen-free problem, its flame retardancy and oil resistance have dropped a lot
[0003] In the existing technology, when preparing TPE yarn, the surface smoothness of the product is improved by increasing the content of polypropylene to ensure flame retardancy and oil resistance. However, due to the high degree of crystallinity, the extrusion speed of the product becomes slower and the production efficiency becomes lower.
In order to solve this problem, some people improve the extrusion speed by adding an external lubricant, but this method has obvious disadvantages, because the external lubricant is easy to precipitate, and the appearance of the yarn will be affected after a long production time

Abstract

The invention discloses a production method of flame-retardant oil-stain-resistant TPE(thermoplastic elastomer) yarn and belongs to the technical field of processing of high-polymer elastomer materials. In the production method, a chemical reaction based graft modification process is adopted creatively, raw materials for productions are adjusted directly, and thus, the TPE yarn produced by the method has smooth surface and is waterpoof, oilproof and nontoxic.

Description

technical field [0001] The invention belongs to the technical field of polymer elastomer material processing, and in particular relates to a production method of flame-retardant and oil-resistant TPE yarn. Background technique [0002] TPE mesh is mainly woven with yarn coated with TPE material (thermoplastic elastomer). The core of the yarn is made of high-strength polyester industrial filament. The silk is stretched and covered, and after drawing and cooling, a composite thread with a smooth surface, waterproof, oil-proof, non-toxic, and cool feeling is formed. Although ordinary TPE solves the halogen-free problem, its flame retardancy and oil resistance have dropped a lot. [0003] In the existing technology, when preparing TPE yarn, the surface smoothness of the product is improved by increasing the content of polypropylene to ensure flame retardancy and oil resistance.
