Abstract
The invention discloses a noise ultra-attenuation color plastic composite polrvinyl chloride drainage pipe and a manufacturing method thereof, belonging to the field of drainage pipes. The wall of the noise ultra-attenuation color plastic composite polrvinyl chloride drainage pipe is of a four-layer composite structure and comprises a color ASA (Acetyl Salicilic Acid) layer, a PVC (Poly Vinyl Chloride) micro-foaming layer, a PVC hollow layer and a PVC internal helical layer from the outside to the inside. Three kinds of noise attenuation, i.e., noise attenuation of a hollow wall structure, noise attenuation of a micro-foaming structure and noise attenuation of an internal helical structure are combined, thus, the drainage noise of the plastic drainage pipe is greatly reduced, the drainagepipe has extremely good noise absorption, noise attenuation and noise insulation effects, and the aim of noise ultra-attenuation of the plastic pipe is achieved. The noise ultra-attenuation color plastic composite polrvinyl chloride drainage pipe has the advantages of keeping the favorable performances such as light weight, corrosion resistance, scaling prevention, flame retardance, wear resistance, good toughness, high impact strength, good gas tightness, capability of recycling, convenience and rapidness in installation, energy saving, sanitation, environment friendliness and the like of the traditional plastic drainage pipe and also has the advantages of excellent anti-aging performance and weather resistance, good noise attenuation effect, varied colors and the like.
Description
technical field [0001] The invention belongs to novel polymer composite materials and belongs to the technical field of plastic drainage pipes, in particular to an ultra-quiet color-plastic composite polyvinyl chloride drainage pipe and a manufacturing method thereof. The main application fields of ultra-quiet color-plastic composite PVC pipes are: building drainage engineering, rainwater recycling engineering, industrial drainage and sewage engineering, municipal drainage and sewage engineering, etc. Background technique [0002] At present, the drainage pipes mainly use polyvinyl chloride pipes and polyethylene pipes. The two pipes have the same defects in use. The pipes have poor anti-aging and weather resistance, and the single color cannot meet the needs of diversified colors. The noise is relatively large when draining water, which is harmful to the environment. The life of the user causes certain troubles. With the development of science and technology and the improv...
