Problems solved by technology

For a long time, it has been widely used to increase the rigidity, hardness, strength and dimensional stability of products by adding inorganic fillers to FRP. However, the types of fillers currently used are relatively single and cannot be well dispersed. In matrix resin and fibers
Therefore, when using it as a filler, the produced FRP products often have the problem of decreased strength and toughness while the rigidity and hardness are increased, and cracks and fragments are prone to occur. In addition, the shrinkage rate of the existing unsaturated polyester resin during curing Larger, the corrosion resistance of the product cannot fully meet the requirements of septic tanks

Abstract

The invention provides a glass fiber reinforced plastic septic tank. The septic tank comprises a septic tank body, and the septic tank body is composed of a sewage inlet, a dirt outlet and a tank body; and the sewage inlet and the dirt outlet are arranged at the left end and the right end of the tank body. Main raw materials for producing the septic tank include methyl benzoate, phthalic anhydride, glutaric acid, fumaric acid, castor oil, neopentyl glycol, styrene, methyl methacrylate, diallyl phthalate, a polymerization inhibitor, polyvinyl acetate, an inorganic filler, an antioxidant, a curing agent, an accelerator, glass fibers and a waste paper pulp. The glass fiber reinforced plastic material has good impact strength, good crack resistance and good corrosion resistance, and a ratio ofparticle with different diameters in the inorganic filler is controlled to make the inorganic filler well dispersed in the unsaturated polyester and effectively fill gaps among the fibers in order toimprove the compactness of the product, so the reinforcing effect of the filler on the material is improved.

Description

technical field [0001] The invention relates to the technical field of FRP septic tanks, in particular to a FRP septic tank and a preparation method thereof. Background technique [0002] FRP, that is, fiber reinforced plastics, generally refers to reinforced plastics made of unsaturated polyester resin as a matrix and reinforced with glass fibers, also known as glass fiber reinforced plastics. It has been developed and applied to civil fields such as septic tanks that are conducive to ecological protection due to its advantages such as electrical conductivity. [0003] FRP septic tanks can effectively solve the problems of leakage of traditional brick-concrete septic tanks, different degrees of pollution to groundwater sources, and tilting of buildings, and can lay the foundation for subsequent advanced treatment of discharged sewage. For a long time, it has been widely used to increase the rigidity, hardness, strength and dimensional stability of products by adding inorga...
