Abstract

The invention provides a high-flame-retardant soft PVC coated polyester yarn high-molecular composite sun-shading material, which is synthesized by PVC resin powder, a flame retardant and other auxiliary materials, wherein the main raw materials of the flame retardant comprise phosphate ester, zinc stannite, metal hydroxide, decabromodiphenyl ethane and antimony trioxide, and simultaneously contain chlorinated polyvinyl chloride and chlorinated paraffin; the coated polyester fiber is woven into a sunlight fabric with high-flame-retardant performance, and the limiting oxygen index can exceed 32.0 %. The high-molecular composite sun-shading material can interact with a gas phase and a solid phase through the compound system, the flame retardancy of the soft PVC coated polyester yarn high-molecular composite sun-shading material is significantly improved, the limiting oxygen index of the material is 32. 4 %, the problem of low limiting oxygen index of the high-molecular composite sun-shading material is solved, the flame retardant efficiency of products is significantly improved, the fire risk of products is reduced, the products are more competitive, this innovation has made a breakthrough in the flame retardancy of soft polymers in the textile field.

Description

technical field [0001] The invention relates to the technical field of macromolecules, in particular to a polymer composite sunshade material with high flame-retardant soft PVC coated polyester filaments. Background technique [0002] Most of the sunshine fabrics on the market are polymer composite materials that are woven from PVC-coated polyester fibers and have the effect of blocking sunlight. The market demand is large and the prospect is broad. However, since the outer skin is soft PVC, the addition of plasticizers significantly reduces the limiting oxygen index, reduces the flame retardant efficiency, and releases smoke and harmful gases when burned. At present, the flame retardant used in soft PVC is mainly antimony trioxide. Although it has excellent flame retardant effect, it has the disadvantages of being unfriendly to the environment and having little smoke suppression effect. [0003] Therefore, in order to further improve the safety of sunshade fabrics, it is ...
