Problems solved by technology

[0003] When PE pipes are stored or used in the open air, under the action of ultraviolet light, especially at the installation site in summer, because polyethylene pipes are generally black, after being exposed to sunlight, the temperature of the pipes is very high, the rigidity drops greatly, and it is easy to deform and easily break out. Aging, discoloration, brittleness or even pulverization, thus losing its mechanical properties and affecting the use of PE pipes, so PE pipes need to be improved to have better anti-aging properties, prolong the service life and expand the scope of use

Abstract

The invention discloses a polyethylene corrugated tubular product. The polyethylene corrugated tubular product comprises the following components in parts by weight: 60 to 90 parts of polyethylene, 15 to 30 parts of fillers, 1 to 5 parts of a heat stabilizer, 0.1 to 1.5 parts of an antioxidant, 0.1 to 1.5 parts of a light stabilizer, 1 to 3 parts of a toughening agent, 1 to 5 parts of modified carbon powder, 1 to 10 parts of polymeric ester calcium, and 1 to 5 parts of silicon dioxide. Compared with the existing tubular product, the polyethylene corrugated tubular product is high in strength, strong in aging resistance and oxidation resistance, good in thermal stability and light stability, greatly improves the impact resistance of the tubular products, and meets the industry standard of construction projects.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a polyethylene corrugated pipe. Background technique [0002] Polyethylene pipe is a high crystallinity, non-polar thermoplastic resin pipe, because PE pipe is non-toxic, tasteless, odorless, good cold resistance, heat resistance and chemical stability, high rigidity and toughness, and With many advantages such as good mechanical properties and convenient installation, it is widely used in building water supply and drainage, buried drainage pipes, gas pipelines and telecommunications engineering and other fields. [0003] When PE pipes are stored or used in the open air, under the action of ultraviolet light, especially at the installation site in summer, because polyethylene pipes are generally black, after being exposed to sunlight, the temperature of the pipes is very high, the rigidity drops greatly, and it is easy to deform and easily break out. Aging, discolorat...
