NOVELTY - Transparent unplasticized polyvinyl chloride (UPVC) pipe material comprises 90-110 pts. wt. polyvinyl chloride, 10-20 pts. wt. crosslinking agent, 50-70 pts. wt. filler, 5-8 pts. wt. stabilizer, 20-40 pts. wt. heat-resistant filler, 6-10 pts. wt. strengthening agent, and 10-40 pts. wt. compatibilizer. USE - Used as transparent unplasticized polyvinyl chloride (UPVC) pipe material. ADVANTAGE - The pipe material: has a more stable molecular chain structure, molecular chain is not easy to move at high temperature, so that UPVC pipe is not easily deformed, and heat resistance of transparent UPVC pipe can be improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the transparent UPVC pipe material comprising mixing polyvinyl chloride, stabilizer, and crosslinking agent, heating to 170-180degrees Celsius, irradiating with ultraviolet light in environment of 170-180degrees Celsius, and cooling to obtain modified polyvinyl chloride; evenly mixing 100-130 parts of modified polyvinyl chloride, filler, heat-resistant filler, strengthening agent and compatibilizer, and carrying out extrusion granulation to obtain masterbatch; and adding the masterbatch into the extruder, setting the extrusion temperature to 180-200degrees Celsius, extruder extrudes the molten masterbatch into the mold of the casting pipe to obtain the hot UPVC pipe, and cooling the hot UPVC pipe step by step by water cooling to obtain UPVC pipe material.
