Abstract

The invention relates to an ultrasoft high-transparency flame-retardant heat-resistant polyvinyl chloride material which is composed of the following raw materials in parts by weight: 50-80 parts of polyvinyl chloride resin WS-1300, 30-40 parts of polyvinyl chloride resin SH-200, 5-10 parts of ethylene-vinyl acetate carbonyl copolymer E / VA / CO, 30-40 parts of trioctyl trimellitate, 10-15 parts of diisodecyl phthalate, 5-8 parts of epoxy soybean oil, 8-10 parts of flame retardant, 1.3-1.9 parts of stabilizer, 0.3-0.5 part of lubricant and 0.8-1 part of antioxidant. The preparation method comprises the following steps: blending the raw materials, and carrying out extrusion granulation in a double-screw extrusion granulator set. The polyvinyl chloride material has the advantages of favorable transparency, favorable flexibility, favorable flame retardancy and favorable heat resistance.

Description

technical field [0001] The invention belongs to the field of new polymer materials, and in particular relates to an extra-soft, highly transparent, flame-retardant and heat-resistant polyvinyl chloride material and a preparation method thereof. Background technique [0002] Some special components, such as automotive thin-walled wire harness materials, heat-resistant electrical wires, speaker wires, and cables that require high transparency, etc., in order to meet the requirements of use, the materials need to have super softness, high transparency, and high flame resistance at the same time resistance and heat resistance. However, it is difficult for ordinary materials to have the above properties at the same time, especially high transparency and high flame retardancy, because the addition of flame retardants will affect the high transparency and softness of the material. [0003] Chinese patent: The invention patent with application publication number CN101768313A and ap...
