Description
Technical field
The present invention relates to plumbing technical field, refer to especially the high temperature resistant super-silent waste pipe of a kind of polypropylene with internal spiral and manufacture method thereof.
Background technique
Along with present information and scientific and technological fast development, the development of construction industry is also very fast, and the height of building is higher, and its requirement to water discharge technology is larger.Building plastic waste pipe comes across the end of the eighties in last century the earliest, and using maximum is PVC＝polyvinyl chloride (PVC) solid wall pipe, but PVC＝polyvinyl chloride (PVC) solid wall pipe waterfall noise is large, reaches 76 decibels.In order to reduce noise, developed successively again hard polyethylene (UPVC) silencing drainage pipe in the nineties, hard polyethylene (UPVC) silencing drainage pipe belongs to mould the energy-conserving product of Dai Gang, UPVC silencing drainage pipe for building be mould for soundproof effect in product made from steel good, but, these effects that reduce noise are limited, the noise that only reduces 5-7 decibel than common PVC solid wall pipe, drainage noise is more than 60 decibels, still very large, the noise of pipe-line system is still higher than cast iron tube, and resistance to high temperature is poor, aging fast, shock resistance is poor, and the life-span is short.
Modern society's commercialize housing development is very fast, provide hot-water supply system compared with big city commercial housing, apartment, office building, restaurant, hotel, physical culture place and recreation center more, even if the house that does not adopt Central Domestic Hot Water to supply with is also all designed with independent heat supply water piping system, conventionally waste discharge temperature is below 40 ℃, but there is considerable possibility chance exhaust temperature at 50-60 ℃, the heat resisting temperature of UPVC silencing drainage pipe is 50 ℃, if be heated for a long time intensity and the working life that can cause tubing heat ageing and reduce tubing.
Along with improving constantly of living standard, people are also more and more higher to building human settlement's requirement, and noise pollution becomes the pollution after atmospheric pollution, human lives being had the greatest impact.During due to high-rise building draining, the underwater sound is seriously polluted, and used UPVC silencing drainage pipe pipeline soundproof effect is poor, heatproof not again, and many developers select flexible iron drain-pipe to replace UPVC silencing drainage pipe at tall building; But although flexible iron drain-pipe soundproof effect is good, perishable, working life is short, not only tubing cost is high, and mounting process complexity, and tubing itself is heavy, and transportation installation cost is high, in addition perishable, installation and maintenance expense is high, and Integrated using cost than the high 3-4 of UPVC silencing drainage pipe doubly.
Summary of the invention
The present invention proposes the high temperature resistant super-silent waste pipe of a kind of internal spiral and manufacture method thereof, has solved in prior art in use large, the non-refractory of noise and the high problem of cost of waste pipe.
Technological scheme of the present invention is achieved in that the high temperature resistant super-silent waste pipe of internal spiral of the present invention, comprise noise reduction layer, described noise reduction layer inwall is provided with screw rib, described noise reduction layer is quiet material layer, and described quiet material layer is made up of the raw material of following weight portion: block copolymerization polypropylene 20-35%, viscous elastomer 5-10%, barium sulphate 50-70%, dispersing agent 2-3%, coupling agent 1-2%, oiling agent 1-2%.
