Polyethylene glue nucleation melting-boosting adhesive special for oil and gas pipelines

The invention discloses a polyethylene glue nucleation melting-boosting adhesive special for oil and gas pipelines. The adhesive comprises the following raw materials in percentage by mass: 60 to 80 percent of polyethylene, 5 to 20 percent of reaction monomer, 0.1 to 1 percent of initiator, 0.5 to 5 percent of nucleating agent, 0.1 to 2 percent of anti-oxidant, and 5 to 25 percent of carbon black,wherein the reaction monomer may be one or more of maleic anhydride, dibutyl maleate or derivatives of acrylamide; the initiator may be one of dibenzoyl peroxide, dicumyl peroxide, ditert-butyl peroxide, tert-butyl hydroperoxide or cumene hydroperoxide; the nucleating agent is selected from benzyl sorbitol derivative series nucleating agent or phosphate salt derivative series nucleating agent; and the anti-oxidant is the main anti-oxidant 1010 and the auxiliary anti-oxidant 618. The adhesive has the advantages of excellent mechanical property, wear-resisting property and thermal property andwide application.
