Abstract

The invention discloses adhesive resin used for a steel band reinforced polyethylene spiral corrugated pipe and a preparation method and applications thereof. The adhesive resin comprises the following raw materials in parts by weight: 20-30 parts of modified grafted polyolefin masterbatch, 55-60 parts of polyethylene, 10-15 parts of tackifying resin, 5 parts of lubricant and 0.3-0.5 part of antioxidant. The preparation method comprises the following steps: mixing the raw materials evenly, performing extrusion reaction, blending and granulating to prepare the finished product. The adhesive resin of the invention has less odor, stable product performance and higher heat resistance and mechanical strength; and the requirements of processing technology of the steel band reinforced polyethylene spiral corrugated pipe can be fully satisfied, and the defects of the products adopting the existing technologies such as high penetrating odor, low heat resistance and mechanical strength and unstable chemical reaction can be overcome.

Description

technical field

[0001] The invention relates to the field of polymer adhesives, in particular to an adhesive resin for steel strip reinforced polyethylene spiral corrugated pipes, a preparation method and application thereof. Background technique

[0002] Steel belt reinforced polyethylene spiral corrugated pipe is a new type of composite pipe that has become popular in recent years, and it is mainly used as a buried drainage pipe. It is a double-wall spiral corrugated pipe that uses high-density polyethylene as the matrix, and a steel strip coated with adhesive resin on the surface to form a corrugated form as the main support structure, and is wound and compounded with polyethylene material. Due to its high ring stiffness and easy installation, it has been widely used in China.

[0003] The adhesive resin on the surface of the steel strip mainly plays the role of connecting the steel strip with the inner layer PE pipe and the outer layer PE. If the bonding is not good, th...
