▎ 摘　　要

NOVELTY - A graphene geo-membrane comprises petroleum resin and graphene at weight ratio of 1:0.003-0.01. The geo-membrane has tensile strength of 24-27 MPa, right-angled tear strength of 108-127 N/mm and water vapor permeability coefficient of 0-1asterisk10-18 g.cm/cm.s.pa. USE - Graphene geo-membrane used in refuse landfill, hazardous waste landfill, radiation waste landfill and/or gas explosion sites (all claimed). ADVANTAGE - The product has higher breaking strength, tear strength and anti-penetrability, and does not generate static. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene geo-membrane comprising uniformly mixing pre-treated graphene with petroleum resin to obtain premixed material, adding into remaining petroleum resin to mix to obtain mixed material, heating and melting, and continuously mixing.
