Polyethylene solid-wall permeation pipe for rainwater collecting and preparing method thereof

Abstract

The invention discloses a polyethylene solid-wall permeation pipe for rainwater collecting and a preparing method thereof, and relates to the technical field of tubular products. The polyethylene solid-wall permeation pipe for rainwater collecting comprises an outer layer, a middle layer and an inner layer from outside to inside. The middle layer comprises, by weight, 100-125 parts of PE, 1-5 parts of a mildew-proof additive, 0.5-1.0 part of a micropore agent, 0.5-1.0 part of a compound stabilizer, 1.0-1.2 parts of a processing aid and 0.5-0.8 part of a color master batch from outside to inside. The mildew-proof additive is a modified silicon dioxide / zinc sulfide quantum dot compound, and modified mesoporous silicon dioxide small spheres serve as the carrier and are loaded with silver-doped zinc sulfide quantum dots. According to the polyethylene solid-wall permeation pipe for rainwater collecting and the preparing method thereof, the mildew-proof additive is added to the formula, thetubular product has good mildew-proof and antibacterial effects, mildew can be effectively prevented from growing on a pipe wall, and the influences on rainwater recycling are reduced.

Description

technical field [0001] The invention relates to the technical field of pipe materials, in particular to a polyethylene solid-wall permeable pipe for rainwater collection and a preparation method thereof. Background technique [0002] In recent years, with the increasing progress of urbanization, more and more areas of urban cementation, coupled with climate change and weakening of environmental carrying capacity, have led to the situation of "every rain will be flooded, and rain will be followed by drought". Frequent occurrences have caused my country's urban water ecology to face two extremes: on the one hand, urban waterlogging is serious during the rainy season, and rainwater management has become a safety hazard affecting urban development; . It also brings a series of problems such as shortage of water resources, water environment pollution, and lack of guarantee of water safety. With the development of social economy and the frequent occurrence of urban rain and flood ...

Problems solved by technology

[0004] Most of the existing pipes used in the construction of sponge cities are made of existing solid-walled pipes, which are made by opening multiple rows of narrow strip-shaped seepage holes around the pipes through special equipment. Ring stiffness and permeability requirements, by wrapping the geotextile outside the pipe, it can not only play a role in infiltrating water, but also prevent the sediment from entering the pipe and causing blockage. , In a dark environment, mold growth is serious, which will not only affect the service life of the pipe, but also cause the water passing through to be polluted, which will seriously affect the recycling of rainwater
