Aging-resistant silver-plastic composite pipe

Abstract

An anti-aging silver-plastic composite tube takes polyethylene, polypropylene or polyvinyl chloride as the matrix material and is composed of an outer tube and an inner tube. The composition and content of the outer tube are as follows (by weight parts): low-density polyethylene (LDPE0 and / or high-density polyethylene (HDPE), polypropylene (PP) or polyvinyl chloride (PVC) 100, silver powder 0.1-10, silver ash 0.1-5, antioxidant 1010 0.5-3, wax 0.5-3 and stearic acid HST 0.5-3. The inner tube is an LDPE, PP, PVC or metal tube. The composite tube in silver-white color has the advantages of good appearance, anti-ageing effect, resistance against deformation, brittle rupture and discoloration, long service life, recyclable materials, reduced material cost, and increased product quality.

Description

technical field [0001] The invention relates to the technical field of plastic composite pipes, in particular to an anti-aging silver-plastic composite pipe. Background technique [0002] At present, due to the advantages of light weight, corrosion resistance, small water loss, energy saving, material saving, ecological protection, and convenient construction, plastic pipes are currently widely used in the fields of building water supply and drainage, urban water supply and drainage, and gas pipes. , common plastic pipes are: rigid polypropylene pipe (UPVC), aluminum-plastic composite pipe, cross-linked polyethylene pipe (PEX), chlorinated polyvinyl chloride pipe (PVC-C), etc., UPVC pipe, PE pipe, PEX pipe Pipes have some shortcomings, such as poor weather resistance, unsightly appearance, and easy damage during construction; aluminum-plastic composite pipes cannot ensure compressive strength, are prone to bursting and leakage, and have high raw material prices.
