A kind of high temperature resistant adhesive resin and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant bonding resin comprising the following raw material components in parts by weight: 20-30 parts of a polypropylene-maleic anhydride styrene co-grafted compound, 20-45 parts of a polyethylene-maleic anhydride styrene co-grafted compound, 10-25 parts of a glycidyl methacrylate grafted ethylene propylene copolymer, 20-50 parts of nylon 6, 5-10 parts of a viscosity regulator, and 0.1-0.5 part of an antioxidant. The bonding resin obtained by the method can be used for bonding steel wires with polyethylene under 40-80 DEG C high-temperature and damp conditions; and the bonding resin belongs to a hot melt adhesive, contains no solvent, has no toxic effect, and has the characteristics of no moisture absorption, corrosion resistance, aging resistance, easy storage and transportation and the like.

Description

technical field

[0001] The invention relates to the field of adhesive compositions, in particular to a special adhesive resin for steel mesh skeleton polyethylene plastic composite pipes and a preparation method thereof. Background technique

[0002] Steel-plastic composite pipe is a new type of composite pipe. Compared with traditional cast iron pipes and plastic pipes, it has the advantages of light weight, anti-corrosion, pressure resistance, wear resistance, low cost, and sanitation. There are many classifications of steel-plastic composite pipes, and steel mesh skeleton polyethylene plastic composite pipes are one of them. The steel wire mesh wrapped in the middle layer of the pipe acts as a partial pressure bearing, so that the pipe has a certain ability to withstand internal pressure. There is no bond between steel wire and polyethylene, so bonding resin must be used in this type of pipe. The steel wire mesh is bonded to the inner and outer polyethylene pipes by bon...
