Plastic pipeline and preparation method thereof

Abstract

The invention discloses a plastic pipeline, which includes the following raw materials: HDPE high density polyethylene, LLDPE linear low density polyethylene, nano zirconium dioxide, nano silicon carbide, nano calcium carbonate, nano bamboo charcoal powder, a silane coupling agent, an anti-aging agent, a defoaming agent, an antistatic agent, an antibacterial agent and titanium dioxide loaded withthe antibacterial agent. Nano zirconium dioxide, nano silicon carbide, nano calcium carbonate and nano bamboo charcoal powder are used as mixed auxiliary materials for preparing the pipeline; the nanoparticles have a large specific surface area, and have a good cross-linking effect with HDPE and LLDPE, the strength of the polymer material can be improved, the thermal stability, wear resistance andcorrosion resistance of the material can be enhanced, a significant acceleration effect is achieved on the plastic pipeline, and the tensile strength of the plastic pipeline can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of pipelines, in particular to a plastic pipeline and a preparation method thereof. Background technique [0002] Winding pipe is a kind of pipe made of high-density polyethylene (HDPE) by winding and welding. Due to its unique forming process, it can produce pipes with a diameter of up to 3 meters, which is difficult to complete by other production processes. Due to its excellent welding performance, high-density polyethylene (HDPE) not only guarantees the product molding process and product quality, but also provides a variety of reliable methods for construction connections, such as electric fusion welding, heat shrinkage connection, etc. At the same time, this It is also an important reason why leakage rarely occurs, and it is precisely for this reason that this kind of pipe has unique environmental protection functions that other pipes do not have, which provides a very effective method for pollution pr...

AI Technical Summary

Problems solved by technology

[0004] 1. In this scheme, the rolling device does not have a good rolling effect on the mold roller, which makes the winding pipe easy to deviate during the winding process, reduces the winding quality of the winding pipe, and cannot well adapt to pipes of different specifications. limitations, and did not clean the processed pipes, which affected the quality of the pipes;

[0005] 2. In this scheme, the heat in the forming process of the winding pipe is not effectively utilized, resulting in the loss of heat during the heating process of the winding pipe;

[0006] 3. Existing plastic pipes exposed to the ground for a long time are prone to aging, deformation, cracking and other problems, and have the disadvantages of poor weather resistance, temperature resistance and mechanical shock resistance
