Layer pipe mold exocoel.
The preparation method of PE gas pipeline 10. a kind of scratch resistance as claimed in claim 7 cracks at a slow speed, it is characterised in that: packet
Containing following steps:
S1. mixing: by heat-proof polythene, polysiloxanes, silane crosslinker, graphene, the polyamide, two to prepare protective layer
Molybdenum sulfide, fiber, maleic anhydride graft copolymer are uniformly mixed at 50~80 DEG C, and mixing time is 3~10 minutes；
S2. it cools down: after the completion of mixing, being cooled to 28~30 DEG C；
S3. protective layer makes: the material completed cooling in S2 step being added in extruder, extruder temperature is set as 150~200
DEG C, extruded velocity is 0.5~20 m/min, and the material completed cooling in S2 step is squeezed into mold by extruder；
S4. it is socketed: after the protective layer of preparation is handled by infrared ray and electric heating case, being coated on existing main structure layer.
