NOVELTY - High-strength and waterproof material comprises 95-105 pts. wt. polyether polyol, 1-10 pts. wt. plasticizer, 10-20 pts. wt. bis (4-isocyanatophenyl) methane, 3-30 pts. wt. graphene/methanesulfonic acid solution, 5-50 pts. wt. additive, 50-80 pts. wt. amino polyether and 20-40 pts. wt. amine chain extender. USE - High-strength and waterproof material. ADVANTAGE - The high-strength and waterproof material is chemical resistant, wear resistant and has good mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of high-strength and waterproof material comprising mixing polyether polyol and plasticizer at 95-100 degrees C and - 0.092 to - 0.096 MPa for 60-90 minutes, cooling to 75 degrees C, adding bis (4-isocyanatophenyl) methane and graphene/methanesulfonic acid solution, stirring at 300-600 revolutions/minute (rpm) for 2-3 hours, adding additives, stirring at 300-600 rpm for 5-15 minutes, cooling to 55-65 degrees C, filtering to obtain mixture A, mixing amino polyether and amine chain extender, heating at 105-115 degrees C and - 0.092 to - 0.096 MPa for 1-2 hours, cooling to 55-65 degrees C for 10-20 minutes, stirring at 300-600 rpm, filtering to obtain mixture B, and mixing mixtures A and B.
