▎ 摘　　要

NOVELTY - A high elasticity weather-resistant thermoplastic elastomer telescopic water pipe comprises 100 pts. wt. maleic anhydride grafted styrene-ethylene-butylene-styrene, 30-40 pts. wt. maleic anhydride-grafted polypropylene, 10-30 pts. wt. white oil, 5-15 pts. wt. modified nanotitanium oxide-hyperbranched polyurethane compound and 5-10 pts. wt. aminated graphene oxide. The modified nanotitanium oxide-hyperbranched polyurethane compound uses aminosilane coupling agent for modifying nanotitanium oxide. USE - High elasticity weather-resistant thermoplastic elastomer telescopic water pipe. ADVANTAGE - The pipe has permanent deformation of less than 15% and excellent weather resistance, and does not break at pressure of 0.8 MPa of continuous water injection for more than 150 times and not brittle during cold or winter. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of high elasticity weather-resistant thermoplastic elastomer telescopic water pipe comprising mixing all raw materials, double screw extruding and granulating, setting into hopper for hot air drying at 60-80 degrees C for 2-4 hours, injection molding at 170-220 degrees C, keeping temperature under low vacuum condition for 0.5-20 hours, and curing.
