One in thing.
The invention has the beneficial effects as follows: the Gas Pipe of the present invention can realize higher toughness and more high-strength simultaneously
Degree, the addition of antistatic auxiliary reduces the electrostatic of polyethylene gas pipe, use safety, impact resistance strong,
Compressive resistance is high, good weatherability, and the addition of lumarith can keep burning line from insect moths such as Coptotermes formosanus Shtrari.
Erosion, improves the service life of pipeline.
On the basis of technique scheme, the present invention can also do following improvement.
Further, part by weight shared by each layer of described body is: PE plastic layer: 15～30 parts, function
Layer: 10～20 parts, insulating: 20～30 parts, lumarith: 15～30 parts.
Above-mentioned further scheme is used to provide the benefit that, each layer rational proportion, improves Gas Pipe further
The rigidity of line, toughness, compressive resistance, safety and service life.
Further, described olefin hydrocarbons thermoplasticity elastic body is in polypropylene, ethylene-propylene copolymer
A kind of.
