High-temperature silencing drainage pipe

Abstract

The invention discloses a high-temperature silencing drainage pipe which is composed of the following raw materials in percentage by mass: the invention discloses a high-temperature silencing drainage pipe which is composed of the following raw materials in percentage by mass: 80-100 parts of polyester fiber, 50-80 parts of polystyrene, 8-10 parts of polycarbonate, 5-8 parts of polyethylene, 3-5 parts of polyvinyl chloride, 2-3 parts of polyethylene terephthalate, 8-10 parts of aluminum sulfate, 5-10 parts of zinc sulfate, 8-10 parts of copper sulfate, 3-5 parts of rosin, 3-5 parts of asphalt, 5-6 parts of sodium alginate, 10-12 parts of polyethylene wax, 10-12 parts of glycerol and 10-12 parts of organic silicone oil. The high-temperature silencing drainage pipe has the advantages of simple structure, low manufacturing cost, favorable mechanical strength and favorable high temperature resistance, and can obviously lower the drainage noise.

Description

technical field [0001] The invention relates to the technical field of a drainage pipe, in particular to a high-temperature silent drainage pipe. Background technique [0002] Domestic silent pipes mostly use composite pipe wall technology, which is mainly composed of inner and outer skin layers and sound-absorbing core layers, of which the inner and outer skin layers are made of PVC resin, impact modifiers, processing modified punishments, stabilizers, lubricants, active CaCO3 fillers, etc. Composition, the fillers of these two layers are low in amount and high in quality, the outer skin layer plays a decorative role, and the inner skin layer plays a role of anticorrosion. The strength of these two layers is higher than that of the core layer, which can ensure that the silent drainage pipe has sufficient mechanical strength to meet the user's requirements. The sound-absorbing core layer has the normal formula of ordinary drainage pipes, and a sufficient amount of sound-abs...
