Problems solved by technology

[0003] my country's hand-woven furniture, handicrafts and decorations are exported to all over the world, generally divided into indoor furniture and outdoor furniture; the woven materials vary according to the requirements of conditions, generally divided into real rattan, plastic rattan, various plant fibers, PE strips, etc. , and the weaving methods are also different. The application of materials in the prior art is relatively traditional and single, and lacks innovation. The compatibility between the matrix is ​​poor, and it is easy to reduce the stability of the finished braided material

Abstract

The invention discloses an environmentally-friendly halogen-free knitting material. The environmentally-friendly halogen-free knitting material is characterized in that modified polyvinyl chloride isprepared through the following raw materials in parts by weight: 100-110 parts of polyvinyl chloride, 10-14 parts of light calcium carbonate, 1-2 parts of oleic diethanolamide, 0.1-0.3 part of butyltin tricaprylate, 20-30 parts of thionyl chloride, 3-4 parts of ricinoleic acid, and 1-2 parts of calcium stearate. According to the method, cyanopropyl methylcellulose is doped for modifying, so that the toughness of the knitting material is effectively improved. The knitting material is safe, high in environmental protection performance, and free from toxic and harmful volatile materials, and canbe processed into various decorative parts.

Description

technical field [0001] The invention belongs to the field of environment-friendly materials, and in particular relates to an environment-friendly halogen-free braided material. Background technique [0002] Polyvinyl chloride is a polymer formed by polymerization of vinyl chloride monomer in peroxide, azo compound and other initiators; or under the action of light and heat according to the mechanism of free radical polymerization. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. PVC is a white powder with an amorphous structure, a small degree of branching, a relative density of about 1.4, a glass transition temperature of 77-90°C, and begins to decompose at about 170°C. It has poor stability to light and heat. When exposed to sunlight, it will decompose to produce hydrogen chloride, and further autocatalyze the decomposition, causing discoloration and rapid decline in physical and mechanical properties. In pra...
