Description
Technical field
The invention belongs to a kind of gutter, specifically, relating to a kind of tube wall is the polychloroethylene mute gutter of the remarkable reduction draining noise of individual layer.
Background technology
The UPVC gutter is with its cheapness, attractive in appearance, installation and maintenance convenience, and application life is longer, extensively adopts in the whole world.But it has a fatal weakness, highrise building or even middle level building, and noise is very big during draining, influences the room peace and quiet, sometimes people is waken up with a start from the dreamland of sweetness.Face of noise, we have done many effort, have developed UPVC foamed sandwich pipe, real wall UPVC inside spin noise reduction pipe, empty wall UPVC inside spin noise reduction pipe, eddy flow denoiser, hydrophilic inwall eddy flow denoiser, rigid polyvinyl chloride eddy flow noise reduction tee junction etc. in succession.External Japanese scholar has done many work, has delivered many patents.But show that through noise measuring the noise reduction of these technology is also not obvious, even the noise reduction of UPVC foamed sandwich pipe is not as good as common UPVC gutter.
My company has developed a kind of quiet pipe for this reason, its patent of invention number: ZL 03135574.9.This quiet pipe is a kind of clad pipe wall technique, and the cross section structure of its pipe as shown in Figure 6.2 and 3 is interior exodermis, by polyvinyl chloride resin, impact modifier, modifier, stabilizing agent, sliding agent, active CaCO
3Filler and pigment are formed.This two-layer amount of filler is few, the quality height, and exodermis plays decoration function, and endodermis plays antisepsis.The strength ratio sandwich layer height that this is two-layer can guarantee that this quiet gutter has enough mechanical strengths, to satisfy user's instructions for use.1 is the sound absorption sandwich layer, it except normal recipe that the normal discharge pipe is arranged and, added the sound absorption function filler of capacity.This quiet gutter can make draining noise decline 14～18dB, residual noise 47～51dB.But along with the raising of people's living standard, people are higher to the requirement of quiet gutter in recent years, wish to reach the requirement of national standard of environmental noise of urban area GB3096-93, and the gutter cost requirement reduces.
Summary of the invention
The object of the present invention is to provide a kind of structural pipe wall simple, cheap for manufacturing cost, can significantly reduce draining noise, can reach again to use the higher single layer wall polychloroethylene mute drainpipe of mechanical strength is installed.
A kind of single layer wall polychloroethylene mute drainpipe, its key is: described single layer wall polychloroethylene mute drainpipe tube wall is an individual layer, contain polyvinyl chloride resin 100 weight portions in the raw material of tubing, barium sulfate 150～350 weight portions, haloflex 10～20 weight portions, reach other relevant processing aids, extrude through double screw extruder and form this kind polychloroethylene mute gutter.
Barium sulfate is the function absorbing material, has high soundproof effect, and when consumption was lower than 150 weight portions, the tubing sound-absorbing effect did not reach the requirement of national standard of environmental noise of urban area GB3096-93, and the gutter cost is too high, and market is difficult for accepting.If the barium sulfate consumption surpasses 350 weight portions, the tubing mechanical properties strength is too poor, does not reach the normal mounting instructions for use, and is difficult to shape.Consumption 50～600 weight portions of barium sulfate are preferably 200～350 weight portions.The average grain diameter of barium sulfate is 2～45 μ m, is preferably in about 10 μ m.Particle diameter is greater than 45 μ m, and the plastic hybrid plasticizing is difficult, and the tubing bad mechanical property does not reach and installs and uses requirement.Use blanc fixe (particle diameter 2～3 μ m), the price height, the tubing cost improves.
CPE is a good auxiliary agent of regulating the tubing impact strength, and consumption is 5～50 weight portions, is preferably 10～20 weight portions, and consumption is less than 10 weight portions, and the tubing shock resistance is too low.Consumption is higher than 20 weight portions, and drawing pipe intensity is too low, and cost improves.Also can adopt MBS, ABS, EVA and KM323B replaced C PE as anti-impact modifier,, can improve the cost of material of quiet pipe greatly because of these four kinds of impact modifier prices are very high.
Other relevant processing aids:
What modifier was used is ACR401 0.5～3 weight portion, also can use PA20, PA21, K-125 and K-120N, promotes the polyvinyl chloride resin plasticizing.
What stabilizing agent was used is compound lead stabilizer TY208 3～5 weight portions, the also compound lead stabilizer of available other models, organic tin stabilizer, calcium/zinc stabilizer or rare-earth stabilizer.Play heat stabilization, make the fixed quiet gutter polyvinyl chloride resin in process of solid wall polyvinyl chloride not decompose rotten.
That sliding agent is used is calcium stearate (CaSt
2) 0.3～0.8 weight portion, in-lubricant; Stearic acid (HSt) 0.5～1.0 weight portion, inside and outside lubricant agent; Paraffin (WAX) 0.3～0.7 weight portion, external lubricant.
What plasticizing agent was used is DOP (phthalic acid two (the 2-ethyl is own) ester) 2～6 weight portions, also can use DIOP (dioctyl phthalate dibutyl ester) or DBP (dibutyl phthalate (DBP)).Play plasticization and processing modified effect.
