Problems solved by technology

[0003] However, the maximum bearing strength of ordinary polyethylene pipes is 1.6Mpa, the wall thickness is relatively thick, the consumables are many, and the cost is high
Moreover, the maximum operating temperature of ordinary polyethylene pipes currently on the market is only 70°C. No matter how high the temperature is, it cannot be used, which limits the scope of use of the pipe and cannot meet the use requirements of high-temperature pipes.

Abstract

The invention discloses a composite polyethylene alloy pipe material. The composite polyethylene alloy pipe material adopts a three-layer composite structure which comprises a high-temperature-resistant polyethylene pipe layer, a fiber winding reinforced layer and an anti-oxidation polyethylene protective layer sequentially from inside to outside. By adoption of a novel formula and a preparation process, the prepared composite polyethylene alloy pipe material has excellent bearing strength, high use temperature and low production cost, and can effectively improve the use effect of products and enlarge the use range of the products.

Description

technical field [0001] The invention relates to a pipe material, in particular to a composite polyethylene alloy pipe material and a preparation method thereof. Background technique [0002] Polyethylene has incomparable wear resistance, impact resistance, chemical resistance, and self-lubricating properties compared to other engineering plastics. It is widely used in various fields of the national economy, especially in wear-resistant transportation, equipment linings, and various mechanical parts. With unique advantages, the development and application of its products have broad prospects, and the development of new application fields is attracting people's attention. [0003] However, the maximum compressive strength of ordinary polyethylene pipes is 1.6Mpa, the wall thickness is relatively thick, there are many consumables, and the cost is high. Moreover, the maximum operating temperature of ordinary polyethylene pipes currently on the market is only 70°C. No matter how...
