FLAME-RETARDANT AND SMOKE-SUPPRESSING SOFT POLYVINYL CHLORIDE COMPOSITE MATERIAL HAVING GOOD MECHANICAL PERFORMANCE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/233028
Kind Code:
A1
Abstract:
The present invention relates to the technical field of polymer materials, relates to a soft polyvinyl chloride composite material, and in particular, to a flame-retardant and smoke-suppressing soft polyvinyl chloride composite material having good mechanical performance and preparation method therefor. The composite material mainly comprises the following components in parts by weight: PVC resin: 100 parts; stabilizer: 2-5 parts; main plasticizer: 20-45 parts; flame-retardant plasticizer: 20-40 parts; flame-retardant and smoke-suppressing agent: 10-20 parts; flame-retardant and smoke-suppressing synergist: 1-5 parts; compatabilizing modifier: 8-15 parts; mechanical performance modifier: 4-10 parts; modifying additive: 1-2 parts; antioxidant: 0-0.5 part; anti-ultraviolet agent : 0-0.5 part; and lubricant: 0-0.4 part. The preparation method for the flame-retardant and smoke-suppressing soft polyvinyl chloride composite material comprises preparing components, mixing the components, and performing extruding granulation by means of a conical twin screw extruder.
