Abstract

The invention provides a high-strength plastic inspection well and a preparation method thereof. The plastic inspection well is prepared from the following raw materials in parts by weight: 20-30 parts of high-density polyethylene, 20-30 parts of polyvinyl chloride, 5-10 parts of powdery nitrile-butadiene rubber, 3-5 parts of stainless steel fiber, 1-3 parts of aid, 0.5-2 parts of coupling agent, 3-6 parts of acrylonitrile-butadiene-styrene copolymer, 1-2 parts of compatilizer, 5-10 parts of mica powder, 5-10 parts of montmorillonite, 1-3 parts of boron nitride fiber, 10-15 parts of polysulfone resin and 5-10 parts of polyoxymethylene. Through the reasonable configuration of the raw materials, the prepared material has excellent comprehensive properties; and the processed inspection well has high strength, rigid, impact strength and corrosion resistance and favorable surface gloss, thereby being better adapted to an underground harsh environment.

Description

technical field [0001] The invention relates to the field of inspection wells, in particular to a high-strength plastic inspection well and a preparation method thereof. Background technique [0002] Inspection wells are set up for easy installation and maintenance of power supply, water supply, drainage, communication, cable TV, gas pipes, street lamp lines, etc. of urban underground infrastructure. It is generally installed at pipeline intersections, turns, pipe diameter or slope changes, and at regular distances on straight pipe sections, so as to facilitate regular inspection, cleaning and dredging, or well-shaped structures for downhole operation and inspection. With the intensification of economic development and urbanization, inspection wells have developed from traditional clay bricks, cement blocks, and prefabricated concrete inspection wells to plastic inspection wells. Plastic inspection wells are generally injection molded sequentially, with fewer steps in the m...
