PVC hybrid resins are poured into and mixed in the high-speed kneading machine that rotating speed is 900~1500 revs/min to 70 DEG C~80 DEG C, Compound stabilizer is poured into high-speed mixer again and continues to mix, then by toughener, compounded lubricant, processing aid, titanium white Powder and filler, which are poured into high-speed mixer, to be continued to mix, until the frictional heat produced by mixing causes the temperature of mixed material Reach and discharged after 110 DEG C~115 DEG C, then mixed material is sent in cooling and stirring device is cooled to 40 DEG C~50 DEG C；4. the mixed material after cooling is sent in the double screw extruder for having been heated to design temperature, mixed material is in warp During crossing double screw extruder, on the one hand it is heated and gradually softens and turn into molten condition, it is on the other hand each during exercise Plant composition further uniformly to mix, finally extruded into strips by die head, grain, air blast cooling, pipeline, vibration are scraped using die head Screening process is sieved, high-impact temperature-resistant material is obtained.Above-mentioned steps 4. in, the precedence that double screw extruder passes through according to material is divided into 4 heating zones and extrusion die, institute The heating-up temperature of each heating zone of setting is followed successively by：T1=150 DEG C~160 DEG C, T2=160 DEG C~170 DEG C, T3=170 DEG C~ 180 DEG C, T4=180 DEG C~190 DEG C, set extrusion die temperature is 180 DEG C~190 DEG C.
