Description

Technical Field

[0001] The utility model belongs to the technical field of drainage pipes, and in particular relates to a high-temperature resistant PVC plastic pipe. Background Art

[0002] PVC plastic pipes are made of polyvinyl chloride resin combined with stabilizers and lubricants, then extruded using a hot-pressing process. They are among the earliest plastic pipes developed and applied. The top layer of this surface coating is lacquer, the middle layer is primarily polyvinyl chloride, and the bottom layer is a backing adhesive. PVC plastic pipes are a popular and widely used synthetic material worldwide due to their light weight, corrosion resistance, high compressive strength, safety, and convenience.

[0003] When PVC plastic pipes in the existing technology are installed outdoors for drainage, they will be exposed to high temperatures for a long time, especially in the summer. Under the action of ultraviolet rays and oxygen, PVC pipes will undergo oxidation reactions, fading and discoloring, becoming brittle and fragile. When the temperature of PVC pipes increases for a long time, they may also decompose and produce toxic gas chlorine, posing a potential threat to the environment and human health.
