Abstract

The invention discloses a polyethylene composite for drip irrigation pipes, belongs to the technical field of high polymer materials, and particularly relates to a polyethylene composite. The polyethylene composite is characterized by comprising the following components in parts by weight: 40-60 parts of high-density polyethylene resin, 20-30 parts of high-pressure polyethylene resin, 10-30 parts of metallocene polyethylene resin, 0.15-1.2 parts of antioxidant, and 1.2-3 parts of carbon black. The composite, besides having good strength, flexibility, processability and aging resistance, has excellent abrasion resistance, ESCR (environmental stress cracking resistance) and puncture resistance and good high-temperature hydrostatic performance.

Description

technical field

[0001] A polyethylene composition for drip irrigation pipes belongs to the technical field of polymer materials, in particular to a polyethylene composition. Background technique

[0002] Due to its good comprehensive properties such as flexibility, cold resistance and processability, polyethylene is widely used in the preparation of various pipes, such as water supply pipes, gas pipes, cable sheath pipes, drainage pipes, agricultural pipes, etc. Drip irrigation pipe (belt) is a kind of agricultural pipe, and it is developing very fast in our country at present. It is required that the raw materials for the preparation of drip irrigation pipes not only have high strength, but also have good flexibility, cold resistance, hydrostatic resistance, environmental stress cracking resistance (ESCR) performance, light aging resistance and heat resistance, etc., and have good performance in the production of pipes. Excellent processing performance, meeting the require...
