Novel polyvinyl chloride (PVC) noise-reduction drainage pipe

Abstract

The invention discloses a novel polyvinyl chloride (PVC) noise-reduction drainage pipe which is prepared from the following components in parts by weight: 50-70 parts of PVC resin, 1-3 parts of plasticizer, 5-10 parts of hexamethylphosphoric triamide, 15-50 parts of barium sulfate, 5-10 parts of thermoplastic polyurethane elastomer, 10-20 parts of plastic resin, 1-2 parts of chlorinated paraffin wax and 10-12 parts of flame retardant. The drainage pipe has the following advantages: excellent noise-reduction effect: the high-density special molecular structure material is utilized to absorb the energy of sound waves, so the noise-reduction effect is better than that of any other pipeline, and the noise value of conventional drainage can be down to 45db below; and favorable shock resistance: the polypropylene material has excellent toughness, can not crack when being subjected to superhigh impact, and can not break even if the pipe is flattened, thereby ensuring the pipe to have favorable shock resistance.

Description

technical field [0001] The invention relates to a novel polyvinyl chloride silent drainage pipe. Background technique [0002] PVC material is good in quality and low in price, and it is currently recognized as the most widely used outdoor water pipe material. However, there are some defects in the existing PVC hose materials. had a great impact. At present, polyvinyl chloride (UPVC) pipes are mostly used for drainage pipes, but its fatal weakness is that it is very noisy when draining. In the face of noise, people have made a lot of efforts to develop core layer foam pipes, spiral pipes, etc. to reduce the noise. Noise when draining. Although these pipes have a certain mute effect, the effect is not satisfactory. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a new type of polyvinyl chloride silent drainage pipe with low cost, good noise reduction effect and ...
