Abstract

The invention relates to a super-high molecular weight polyethylene reinforced pipe and a preparation method and production equipment thereof. The polyethylene reinforced pipe is characterized in that: a plurality of longitudinal reinforcing ribs are arranged on an outer wall of a pipe body. The super-high molecular weight polyethylene reinforced pipe comprises the following components in part by mass: 100 parts of super-high molecular weight polyethylene, 3 to 6 parts of talcpowder, 0 to 1.0 part of graphite and 0 to 25 parts of flame retardant antistatic material. A plastic reinforced pipe is directly extruded and molded; and the polyethylene reinforced pipe has the characteristics of low investment, is easy and convenient to produce and is practicable. The problem that the super-high molecular weight polyethylene reinforced pipe bends or hangs downwards during use is solved, and a super-high molecular weight polyethylene large-caliber ultra-thin wall pipe is extruded and molded. Because the talcpowder serves as a lubricating agent, the production loss of raw materials can be reduced by 2 percent; and due to the design of the reinforcing ribs, compared with a common super-high molecular weight polyethylene pipe, the reinforced pipe has a wall thickness which can be reduced by over 20 percent under the conditions of the same pressure and the same caliber.

Description

technical field [0001] The invention relates to a special pipe material in the field of industrial transmission, in particular to an ultra-high molecular weight polyethylene reinforced pipe material and a preparation method and production equipment thereof. Background technique [0002] In recent years, plastic pipes have developed rapidly, and many new plastic pipes are being promoted and applied, and replacing steel with plastic is a major trend. UHMWPE pipes are gradually recognized by the market as a new material with particularly excellent properties. However, the ultra-high pipe ring produced by the existing technology has poor rigidity, and is seriously bent and sagged during use; the large-diameter thin-walled pipe is easy to flatten and deform, and cannot be produced, and its application is very limited. It is theoretically feasible to set reinforcing ribs on the UHMWPE pipe and use the principle of I-beam to improve ring stiffness and pressure resistance. [0003...
