High strength corrugated pipe

Abstract

The invention discloses a high strength corrugated pipe, which is mainly formed by PE resin raw materials, and is characterized by further comprising 4-5 percent of compound stabilizer, 5-6 percent of chlorinated polyvinyl chloride, 2-3 percent of processing agent ACR, 2-3 percent of metal powder and 1-2 percent of color master. The compound stabilizer, chlorinated polyvinyl chloride, processing agent ACR, metal powder and color master are added in the PE resin raw materials as per a certain proportion, so that a series of properties of a product are improved, and the requirements for poor environment and occasions of load bearing strength can be satisfied. In addition, calcium carbonate and stearic acid are added into the raw materials, so that the product is enabled to be shaped easily, and the scratch resistance of the surface of the product is realized.

Description

technical field [0001] The invention relates to a bellows, in particular to a bellows with high strength. Background technique [0002] The molecule of polyethylene is a long-chain linear structure or branched structure, which is a typical crystalline polymer. In the solid state, the crystalline part coexists with the amorphous form. The degree of crystallinity varies depending on the processing conditions and original treatment conditions. Generally, the higher the density, the greater the degree of crystallinity. The crystallinity of L.DP E is usually 55%-65%, and the crystallinity of HDPF is 80%-90%. Polyethylene is a typical thermoplastic, because of its odorless, tasteless and non-toxic characteristics, it has been popularized and used. Polyethylene has good chemical stability. It can resist acid at room temperature and is not resistant to strong oxidation corrosion. Especially for harsh climate environments with relatively large ozone content, it will affect the ser...

Problems solved by technology

Polyethylene has good chemical stability. It can resist acid at room temperature and is not resistant to strong oxidation corrosion. Especially for harsh climate environments with relatively large ozone content, it will affect the service life and aging resistance of polyethylene pipes; in addition, the existing polyethylene The impact resistance and ring stiffness of vinyl pipes cannot meet the actual production requirements for occasions with relatively large load capacity.
