Abstract

The invention discloses a high temperature mute drainpipe, tubing raw materials of which comprise the followings, by weight: 25-30% of PP-B, 5-10% of high-molecular elastomer, 55-60% of barium sulfate, 1-3% of coupling agent, 0.3-0.8% of paraffin, 0.2-1.0% of stearate, 0.1-0.5% of white oil, and 0.5-1.0% of processing auxiliary agent. All the raw materials are mixed and extruded by a double-screwextruder to obtain the high temperature mute drainpipe. The high temperature mute drainpipe of the present invention has a density larger than 1400kg / m<3>, a vertical retraction rate of 0.47% and a Vicat softening temperature higher than 140DEG C. In an indoor equipressure contrast test with a same drainage device, a cast iron pipe, a PVC solid wall tube, a PVC hollow spiral pipe and the high temperature mute drainpipe of the present invention are used. And the high temperature mute drainpipe of the present invention is superior to the cast iron pipe, the PVC solid wall tube and the PVC hollow spiral pipe.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage, in particular to a drainage pipe, in particular to a high-temperature silent drainage pipe. Background technique [0002] UPVC drainage pipe is widely used all over the world because of its low cost, beautiful appearance, convenient installation and maintenance, and long service life. But it has a fatal weakness. High-rise buildings or even middle-rise buildings make a lot of noise when draining water, which affects the quietness of the living room and sometimes wakes people up from their sweet dreams. In the face of noise, some people in the industry have done a lot of work, and have successively developed UPVC core foam pipes, solid wall UPVC inner spiral noise reduction pipes, empty wall UPVC inner spiral noise reduction pipes, swirl noise reducers, and hydrophilic inner wall swirl pipes. Noise reducer, rigid polyvinyl chloride swirl noise reduction tee joint, etc., foreign ...
