Description

technical field

[0001] The invention belongs to the technical field of materials, and in particular relates to a special material for heat-resistant polyethylene steel skeleton reinforced composite pipes and a preparation method thereof. Background technique

[0002] Plastic products are widely used in our lives, such as daily necessities, automobiles, aerospace and so on. In the field of transportation, plastic pipes play a very important role. Compared with traditional metal pipes, plastic pipes have light weight, corrosion resistance, high compressive strength, sanitation and safety, small water flow resistance, energy saving, metal saving, and life improvement. Environmental protection, long service life, safety and convenience, etc., are favored by the pipeline engineering industry. The development of plastic pipes not only promotes the development of manufacturing plastic pipes, but also can develop related fields such as plastic material modification research, formul...
