Abstract

The invention provides a UPE-T material and a preparation method thereof and a UPE-T double-wall reinforced winding pipe. The preparation method comprises the following steps: including ultra high molecular weight polyolefin UPE, modified PET and 25-40 parts of active sliding powder; and mixing the raw materials, and performing melt granulation through a double-screw extruder to obtain the UPE-T material composite material, wherein the temperatures of charging barrels are 190 DEG C, 205 DEG C, 215 DEG C, 220 DEG C and 220 DEG C respectively, and the temperature of a mouth mold is 215 DEG C. Modified PET, talcum powder and polyolefin are adopted to form a composite material UPE-T, the composite material UPE-T is used for producing the inner wall and the outer wall of the UPE-T double-wall reinforced winding pipe, a high-strength bonding material is formed by mixing resin HMCRP100N special for a high-density polyethylene pipe and a polyethylene copolymer adhesive GS101, the ring stiffness and the ring flexibility of a prepared pipe lining are obviously improved by 40%-60%, and the performance requirement of a large-caliber underground drainage blow-off pipe can be met.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and in particular relates to a UPE-T material, a preparation method and a UPE-T double-wall reinforced winding pipe. Background technique [0002] At present, traditional reinforced concrete pipes, ceramic pipes, cast iron pipes, and ordinary plastic pipes are still the mainstream of my country's drainage pipe network system, but their construction is difficult and the connections between pipes are complicated, often resulting in huge construction waste. Especially in long-term use, often due to corrosion, damage, leakage, especially large-scale sewage leakage, less and less underground water sources have been seriously polluted. Solving the problem of water shortage and pollution in the city is related to the sustainable development of the city, and it is also a major issue for the current and long-term development of our country. According to the development of plastic pipes in devel...
