Problems solved by technology

Many existing septic tanks have serious corrosion, low strength, and leakage due to factors such as unreasonable design and poor quality, which greatly shorten the service life. For example, those made of bricks, reinforced concrete or steel plates Septic tanks have different degrees of leakage, which seriously pollutes groundwater and endangers people's health.

Abstract

The invention provides high-strength corrosion-resistant plastic for a septic tank. The high-strength corrosion-resistant plastic is prepared from 50 to 70 parts by mass of linear low-density polyethylene, 40 to 60 parts by mass of polypropylene, 8 to 12 parts by mass of attapulgite, 4 to 9 parts by mass of phytic acid, 10 to 16 parts by mass of mica flake, 3 to 10 parts by mass of silicon carbonate whiskers, 15 to 22 parts by mass of nanometer calcium carbonate, 5 to 10 parts by mass of polyurea, 2 to 5 parts by mass of an antioxidant, 2 to 4 parts by mass of an antistatic agent, 3 to 5 parts by mass of methacryloxypropyltrimethoxysilane and 0 to 2 parts by mass of vinyl acetate. The high-strength corrosion-resistant plastic has excellent resistance to penetration, acid and base corrosion resistance, high and low temperature resistance, mechanical strength, impact strength greater than or equal to 74 kJ/m<2>, tensile strength greater than or equal to 44 Mpa, a heat distortion temperature greater than 90 DEG C and a cold deformation temperature less than -37 DEG C.

Description

technical field [0001] The invention relates to the technical field of plastic septic tanks, in particular to a high-strength corrosion-resistant plastic for septic tanks. Background technique [0002] Septic tank is a treatment facility that uses the principle of sedimentation and anaerobic fermentation to remove suspended organic matter in domestic sewage, and is a primary transitional living treatment structure. Many existing septic tanks have serious corrosion, low strength, and leakage due to factors such as unreasonable design and poor quality, which greatly shorten the service life. For example, those made of bricks, reinforced concrete or steel plates Septic tanks all have different degrees of leakage, which seriously pollutes groundwater and endangers people's health. Contents of the invention [0003] In view of the above existing problems, the present invention proposes a high-strength corrosion-resistant plastic for septic tanks, which has excellent permeabili...
