Abstract

The invention discloses a PVC-U drainage pipe with a noise reduction characteristic, and relates to the technical field of new materials. The PVC-U drainage pipe with the noise reduction characteristic includes, by mass, 15-17% of gamma-(methacryloxy) propyl trimethoxysilane modified perlite and 6-8% of gamma-aminopropyl triethoxysilane modified potassium feldspar powder. The prepared PVC-U drainage pipe has a good noise reduction effect.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a PVC-U drainage pipe with noise reduction characteristics. Background technique [0002] Drainage pipes play an important role in daily life. Drinking water, daily sewage, rainwater utilization, etc. are all supplied or discharged through drainpipes. [0003] PVC-U drainage pipe has the advantages of low price, beautiful appearance, convenient installation and maintenance, and long service life, and is widely used all over the world. But it has a big disadvantage that it makes a lot of noise when draining water, which affects the quietness of the living room. During the drainage process of the building drainage pipe, the water flows downward and the air in the pipe flows upward. When the water flow is large, a water plug will be formed in the pipe, which will collide with the rising air flow and generate a large noise. Therefore, how to improve the noise red...
