Problems solved by technology

[0003] At present, FRP septic tank storage tanks are generally buried 0.7 to 3.5 meters underground to save ground space. The ground can be used for greening, squares, roads, parking lots, etc. Therefore, the underground tank body needs to withstand the upper soil pressure, side pressure, Due to multiple pressures such as ground load (such as ground parking or vehicle traffic pressure) and uneven geological settlement stress, the tank body must have sufficient strength to withstand external forces, so high requirements are placed on the performance of the FRP septic tank itself. , but the existing technology has the problem that the surface of the buried storage tank is easily corroded, and the compression and bending resistance are insufficient.

Abstract

The invention discloses a production process of a high-strength high-toughness glass-fiber-reinforced septic tank. The production process comprises the following steps: uniformly mixing styrene and 2,6-ditert-butyl para-cresol, and adding the mixture into an unsaturated polyester resin; sequentially adding a vinyl ester resin, an initiator, calcium hydroxide, polyoxyethylene castor oil and zinc stearate to be uniformly mixed; adding magnesium oxide, and uniformly mixing to obtain premix; adding reinforced fibers into the premix, uniformly kneading in a kneading machine, feeding into an extruder for extrusion, pouring into a mold, performing mold curing and molding, and demolding, thereby obtaining the high-strength high-toughness glass-fiber-reinforced septic tank. According to the production process of the high-strength high-toughness glass-fiber-reinforced septic tank provided by the invention, the produced septic tank has high strength and high toughness, also has corrosion resistance, and is long in service life and excellent in processability.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a production process of a high-strength and high-toughness FRP septic tank. Background technique [0002] Septic tank is an indispensable drainage treatment equipment in the field of construction. It is used to discharge domestic wastewater into municipal pipelines after primary treatment or into lower-level sewage treatment facilities for advanced treatment. In the early days, septic tanks were usually made of bricks, reinforced concrete or steel plates, but they all had obvious defects. In recent years, glass fiber reinforced plastic septic tanks have gradually been selected by most construction units. The scientific name of FRP is glass fiber reinforced plastic, and the septic tank storage tank made of FRP has the characteristics of strong corrosion resistance, no leakage, easy construction, and slow aging speed. The service life can reach more than 50 years. [0003...
