Description

Three layers of compound noise reduction plastic drain-pipe core material and preparation method thereof, application
Technical field
The present invention relates to a kind of plastic drain-pipe core material, particularly a kind of three layers of compound noise reduction plastic drain-pipe core material, its preparation method and application, belong to materials for construction technical field.
Background technology
Water shoot for building, the past adopts cast iron pipe mostly.Since reform and opening-up, the housing construction high speed development of China, the production of cast iron pipe can not meet demand far away, and the Ministry of Construction advocates energetically and promotes the use of plastic drain-pipe for this reason.Because plastics tubing cost is low, easily process, light weight, constructability, current cast iron pipe is eliminated substantially.The greatest drawback of plastic drain-pipe is that noise is large, especially for Highrise buildings, has a strong impact on resident's orthobiosis and rest.To disturb residents problem to solve noise, insider has thought thousand and one way: such as successively develop foamed sandwich pipe, spiral inner wall pipe etc., the appearance of these product innovations, although noise (can 2 ~ 3dB be reduced) can be reduced to a certain extent, but do not reach the level of cast iron pipe far away, and cost and intensity also can not show a candle to real wall plastics and run well.
The noise of water shoot is combined by pneumatic sound transmission and admittedly dynamic sound transmission.Be full of air in drainage pipeline, when water discharges from top to bottom, existing take air as the sound wave transmission of medium, has again and causes pipe to shake the noise formed because water and solid sundries flow to clash into tube wall.Therefore to reduce the noise in plastic drainage pipeline, first just require that the material of plastics tubing can absorb and shake for the sound wave of medium clashes into tube wall with minimizing because water and solid sundries flow the noise produced with air.Why noise is little for cast iron pipe, is because the density of cast iron is large, and tube wall vibrations difficulty, the noise produced is also just little, and density is large simultaneously, and soundproof effect is good, namely absorbs sound wave efficiency high.The present invention is exactly according to this principle, and adopt the maximum natural barite powder of density to make the material of main part of water shoot core material, adding proportion is up to nearly 80%.In addition, in order to ensure the intensity (i.e. tubing intensity) of core material, formulating of recipe is also dosed the wollastonite powder that a certain amount of threadiness can play reinforcing bar effect, and with high active surfactant to the process of inorganic powder Surface coating.In Choice of Resin, adopt good toughness and there is the resin complexes of certain elastic multiple different performance, making tubing core material guarantee, under highdensity prerequisite, good intensity can also be had.Although also have report three layers of compound noise reduction plastic drain-pipe production technology, because core material density only has 2.0 ~ 2.5g/cm at present 3(core material density of the present invention is 3.8 ~ 4.0g/cm 3), erasure effect does not far reach the level of cast iron pipe.
The core material body material of noise reduction plastic drain-pipe prepared by the present invention is cheap natural inorganic powder, and more than 80% of three-layer composite pipe gross weight shared by core material, so the three-layer composite pipe not only good muffling effect prepared for main body with this core material, close to or be better than cast iron pipe, and intensity is better than pure plastic entity pipe, cost is low, only has 60% of pure plastic entity pipe cost, therefore the present invention had both had good social benefit, there is again obvious economic benefit.
