▎ 摘　　要

NOVELTY - An outdoor PVC transparent window material comprises 30-40 pts. wt. PVC resin, 6-16 pts. wt. calcium carbonate, 4-10 pts. wt. aluminum hydroxide, 3-9 pts. wt. nano carbon black, 2-6 pts. wt. calcium-zinc composite stabilizer, 4-10 pts. wt. nano titanium dioxide, 3-9 pts. wt. nano zinc oxide, 1-3 pts. wt. heat stabilizer, 2-6 pts. wt. antibacterial agent and 2-5 pts. wt. antiwear agent. USE - As outdoor PVC transparent window material. ADVANTAGE - The preparation method is simple, and the prepared window material has excellent wear resistance, antibacterial properties, aging resistance and high transparency. The transparent state of the outdoor window is ensured, and no fogging frost phenomenon is occurred. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the outdoor PVC transparent window material comprising (S1) mixing PVC resin, calcium carbonate, aluminum hydroxide, nano carbon black, a calcium-zinc composite stabilizer, nano titanium dioxide and nano zinc oxide, and putting the mixture into a high-speed mixer for mixing to obtain a mixture (A), (S2) sequentially adding a heat stabilizer, an antibacterial agent and an antiwear agent to the mixture (A), and fully mixing at normal temperature to obtain a mixture (B), and (S3) putting the mixture (B) into a double-screw extruder for extrusion granulation to obtain the PVC transparent window material.
