Abstract

The invention provides a universal adhesive resin master batch for a composite pipe. The universal adhesive resin master batch comprises the following components in percentage by weight: 30%-90% of anethylene copolymer, 9%-60% of an elastomer, 0.1%-5% of a grafting monomer, 0.1%-2% of an initiator and 0.1%-2% of a coupling agent. The invention also provides a preparation method of the universal adhesive resin master batch for the composite pipe. The universal adhesive resin master batch for the composite pipe can adapt to the adhesion characteristics of various composite pipes such as a steelwire wound reinforced pipe, a steel-plastic composite pipe, an aluminum-plastic pipe and a steel belt pipe; the same master batch is applicable to various adhesive resins, so production process is simplified, product stability is favorably controlled, and production cost is reduced; and in addition, the master batch disclosed by the invention can also be mixed with original master batch for use together, so the adhesive property of an original formula system is remarkably improved.

Description

technical field [0001] The invention relates to the field of adhesive resin masterbatches, in particular to a general-purpose adhesive resin masterbatch for composite pipes and a preparation method thereof. Background technique [0002] Composite pipe is a kind of pipe made of plastic material and metal. It can combine the characteristics of hygiene, corrosion resistance and light weight of plastic with the advantages of high strength of steel, aluminum and other metals, and has a unique market application space. Since plastic and metal are materials with greatly different properties, they cannot be directly integrated, and the middle layer must be bonded with resin to make the two tightly bonded. [0003] At present, in the field of composite pipes, the main materials used for plastics are polyethylene, polypropylene or polyvinyl chloride, and the metals are mainly steel, aluminum, etc. (wire or strip), and the adhesive resin used should be produced according to the specifi...
