Abstract

The invention provides an adhesive resin for an anti-ultraviolet aging type steel wire mesh framework polyethylene composite pipe. The adhesive resin comprises the following components by mass: 20-40 parts of modified polyethylene; 30-50 parts of a functional polymer; 10-20 parts of phenol resin; 1-10 parts of filler; and 1-3 parts of a stabilizer. The adhesive resin provided by the invention has the advantages of high peel strength, high tensile strength, high bonding strength, excellent ultraviolet aging resistance and high mechanical property retention rate after long-time sunlight irradiation, has great significance in enhanced production of composite pipes, and due to the excellent ultraviolet aging resistance, the prepared steel wire mesh framework polyethylene composite pipe is long in service life, and the enhanced production and the service life prolonging of the composite pipe are greatly improved.

Description

technical field [0001] The invention relates to the technical field of adhesive resins, in particular to an adhesive resin for anti-ultraviolet aging steel mesh skeleton polyethylene composite pipes. Background technique [0002] In the production of steel mesh skeleton polyethylene composite pipe, the main function of the bonding resin is to bond the non-polar polyethylene layer and the steel wire layer. However, during processing, storage and use, adhesive resins are often affected by external environmental factors such as light, heat, oxygen, moisture, toxic and harmful gases, and microorganisms to age. Aging will not only lead to the deterioration of its appearance quality, but also cause irreversible changes in physical and chemical properties, which are manifested in the decline of mechanical properties, and eventually lose the value of use due to the decline in service performance, and destroy the steel mesh skeleton polyethylene composite pipe. structure, laying hid...
