The invention discloses a heat-resistant cross-linked high-density polyethylene pipe which is prepared from the following raw materials: high-density polyethylene, polybutadiene, 3-methacryloxy trimethoxy silane, montmorillonite powder, ethylene-vinyl acetate copolymer, styrene-maleic anhydride copolymer, olefin processing mixed aid, lubricant, cross-linking agent, auxiliary cross-linking agent, polycarbosilane, N-ethyl o-toluenesulfonamide, 4' -diaminodiphenyl sulfone, ethylene-octene copolymer, cobaltous oxide, resorcinol and cordierite powder. The heat-resistant cross-linked high-density polyethylene pipe disclosed by the invention has the advantages that the heat resistance and the creep resistance are improved, the aging resistance, the mechanical property, the transparency and the like are obviously improved, and the cross-linking degree is improved, so that the performances are improved more obviously. And has better chemical resistance and flexibility. |
