Abstract

The invention provides a UPP-T material, a preparation method and a UPP-T high-strength inspection well. The preparation method of the UPP-T material comprises the following steps: mixing ultra-high molecular weight polyolefin, modified polyethylene glycol terephthalate and active talc powder, and then conducting melting and granulating through a double-screw extruder to obtain the UPP-T material. According to the invention, the modified UPP-T, talcum powder and polyolefin are adopted to form the composite material, the ring stiffness and the ring flexibility of the inspection well prepared from the composite material are obviously improved compared with those of the conventional common PP plastic modification and can be improved by 30-40%, and the performance requirements of the large-caliber underground drainage and pollution discharge inspection well can be met.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and in particular relates to a UPP-T material, a preparation method and a UPP-T high-strength inspection well. Background technique [0002] At present, my country's drainage pipe network system still uses ordinary polypropylene PP modified plastics as the mainstream for traditional inspection wells, but its materials have low impact performance, high brittleness, and poor temperature resistance. Therefore, the plastic inspection well ring produced has fatal defects such as low rigidity, poor ring flexibility, high brittleness, easy damage, easy leakage, poor temperature resistance, small production caliber, and embedded depth not exceeding 3m. Furthermore, the difficulty of engineering construction is high, and the connection between inspection well pipelines is complicated, which often results in huge construction waste. Especially in long-term use, the pre-buried depth of ordinary i...
