Abstract

The invention provides a grafted polyethylene hot-melt adhesive specially used for steel mesh skeleton polyethylene composite pipes, which is characterized in that, in parts by mass, its components include: 100 parts of compound carrier, composed of HDPE:POE : LDPE: LLDPE is compounded according to the ratio of parts by mass of 5:1:1:3; the compound initiator is 0.1-0.3 parts, which is composed of dicumyl peroxide (DCP) and 2,5-dimethyl-2, 5-bis(tert-butylperoxy)hexane (BPDH) is compounded according to the ratio of 1:1 to 1:3 in parts by mass; 1 to 3 parts of maleic anhydride, the mass parts of composite initiator and maleic anhydride The ratio is 1:10. At the same time, the preparation method of the grafted polyethylene hot-melt adhesive used for the PE pipe with steel mesh skeleton is also disclosed. The hot melt adhesive has high bonding strength with the steel wire mesh, and the product has excellent fluidity, and the shear strength with the steel wire is ≥16Mpa.

Description

Technical field [0001] The invention relates to the field of hot melt adhesives, in particular to the field of grafted polyethylene hot melt adhesives for steel mesh skeleton PE pipes and preparation methods. technical background [0002] The steel mesh skeleton poly PE composite pipe is a mesh skeleton formed by a high-strength steel wire spirally formed left and right, and a high-density polyethylene (HDPE) as the matrix. The steel mesh skeleton is connected to the inner and outer layers with high density with hot melt adhesive. The polyethylene is tightly joined together. [0003] However, the shear strength of commonly used hot melt adhesives and steel wire meshes on the market is often only about 10 MPa, which cannot achieve the use environment with high shear strength requirements. [0004] Although there is a grafted hot-melt adhesive product on the market that can improve the shear strength of hot-melt adhesive and steel mesh, the pursuit of high grafting rate leads to incre...
