Problems solved by technology

The permafrost layers in these cold regions are mostly below 1.5 meters, or even as deep as 3 meters, which increases the difficulty of on-site construction, and also greatly increases the strength and load requirements of the septic tank itself, and the cleaning pipes also need to increase accordingly.

Abstract

The invention belongs to the technical field of glass fiber reinforced plastic, and discloses a heat insulation septic tank and a preparation method thereof. The preparation method includes: grindingcalcium silicate or aluminum silicate forming a filler into powder with a particle size less than 45 microns; stirring and mixing resin, the powder filler, a curing agent, a mold release agent and a thickening agent according to proportion to form resin paste, and allowing the resin paste to evenly permeate glass fiber or glass cloth to form a sheet material through a sheet machine; then curing, and filling the cured sheet material into a mold cavity for compression molding to form modules forming the heat insulation septic tank; and splicing the modules to form the heat insulation septic tank. The heat insulation septic tank prepared by the method has good heat insulation effect, also has the characteristics of high bending strength and tensile strength, is particularly suitable for beingused in toilets in northern cold regions, and has the characteristics of low production and construction costs.

Description

technical field [0001] The invention belongs to the technical field of glass fiber reinforced plastics, and discloses a heat-insulating septic tank prepared by using a novel SMC composite material. The composite material is especially suitable for the preparation of an underground septic tank used for changing toilets in cold northern regions. Background technique [0002] Traditional septic tanks are molded from ordinary SMC materials. In northern regions such as Inner Mongolia, Heilongjiang and other cold regions with deep permafrost, the septic tank needs to be buried deep under the permafrost to avoid damage due to The water in the septic tank freezes and bursts. The permafrost layers in these cold regions are mostly below 1.5 meters, or even as deep as 3 meters, which increases the difficulty of on-site construction, and also greatly increases the strength and load requirements of the septic tank itself, and the cleaning pipes also need to increase accordingly. .
