SMC drain pipe and preparation material and preparation method thereof

Abstract

The invention discloses an SMC drain pipe and a preparation material and a preparation method thereof; the SMC drain pipe comprises a water inlet pipe and an anti-blocking cover, wherein the water inlet pipe is prepared from the SMC drain pipe preparation material; the anti-blocking cover is embedded in the upper part of the water inlet pipe; the SMC drain pipe preparation material is composed of the following materials by the weight fraction: 20%-28% of unsaturated polyester resin, 5%-8% of short thick glass fibers, 20%-32% of medium-alkali glass fiber cloth, 25%-38% of a filler, 8%-15% of industrial waste residues, 10%-20% of glass powder, 0.5%-2.0% of an internal demolding agent, 1%-2.8% of a low-shrinkage additive, 0.5%-2.5% of a chemical thickening agent, 0.2%-1.0% of an initiator, and 0.5%-4.5% of a coloring agent. The preparation method comprises calcining, foaming, annealing and cooling, raw material mixing, impregnation, sheet preparation and finished product obtaining. According to the SMC drain pipe and the preparation material and the preparation method thereof, with foam glass and the SMC material structure, the drain pipe has the advantages of both the foam glass and the SMC material, and has the advantages of low production costs, long service life, and excellent electrical insulation performance, mechanical properties, thermal stability, and resistance to chemical corrosion.

Description

technical field [0001] The invention relates to an SMC drain pipe, a preparation material and a preparation method thereof, and belongs to the technical field of SMC products. Background technique [0002] Drainage pipes are an important part of drainage facilities. They are mainly used for vertical and horizontal drainage and permeation of expressways, drainage of tunnels and underground passages, water supply and drainage of municipal engineering, water purification plants, sewage plants, garbage dumps, golf courses, sports grounds, etc. Drainage of resting green spaces such as parks and parks, water and soil conservation of hillside development slopes, underground drainage of land preparation projects, etc.; the existing drainpipes are mainly made of two kinds of materials: metal materials and organic materials; drainpipes made of metal materials Water pipes, such as cast iron drain pipes, are pipes made of high-density steel with other additives added. The structure of t...

[0002] Drainage pipes are an important part of drainage facilities. They are mainly used for vertical and horizontal drainage and permeation of expressways, drainage of tunnels and underground passages, water supply and drainage of municipal engineering, water purification plants, sewage plants, garbage dumps, golf courses, sports grounds, etc. Drainage of resting green spaces such as parks and parks, water and soil conservation of hillside development slopes, underground drainage of land preparation projects, etc.; the existing drainpipes are mainly made of two kinds of materials: metal materials and organic materials; drainpipes made of metal materials Water pipes, such as cast iron drain pipes, are pipes made of high-density steel with other additives added. The structure of this material is firm, but the interface between it and concrete has poor durability and is easy to form weak seepage channels; organic materials The finished drain pipe, such as polyvinyl chloride drain pipe, is light in weight and does not rust, and the price is relatively low, but the interface between the PVC drain pipe and concrete has poor durability and is prone to leakage
