Abstract
The invention relates to a high-temperature resistant low-noise drain pipe which consists of an inner layer, a middle layer and an outer layer, the inner layer and the outer layer consist of 50-90% of polypropylene random copolymer, 9-45% of calcium carbonate and 1-5% of masterbatch, the middle layer is made of polymer filling materials, and the main components comprise 20-80% of polypropylene block copolymer, 20-80% of silicon dioxide (or calcium carbonate), 0.3-2% of lubricant and 0.5-5% of masterbatch. The drain pipe can be used under a high temperature environment at about 90 DEG C for a long time, the surfaces of the inner layer and the outer layer are very smooth, the calcium carbonate is added in the middle layer for playing the role of absorbing sound, thereby effectively reducing the noise when being passed by water flow; furthermore, the raw materials do not contain lead, barium and other harmful substances, thereby being more conductive to meeting the requirements of people on sanitation and environmental protection.
Description
Technical field
The present invention relates to a kind of building field and industrial field drainage pipe, especially a kind of can resistant to elevated temperatures low-noise drain pipe.
Technical background
People generally use pvc pipe as drainage pipe in building field and industrial field at present, also use pvc pipe as water supply and sewerage pipeline in a large number in the house that people live, but find that in use its anti-impact force of existing P VC pipeline is generally relatively poor, influenced by external force factor and cause it to damage, serious meeting causes water pipe to break, its noise is also bigger when current pass through, the life that influences people is had a rest, and this class pvc pipe is owing to all added harmful lead in life process, materials such as barium, long-term use meeting brings severe impairment to people's health, thereby its environment is also relatively poor, the continuous change of living simultaneously along with people, use the situation of high-temperature-hot-water more and more, the Temperature at discharging condensate of present domestic bowl-washing is generally all about 90 ℃, and because the Vicat softening point of pvc pipe generally about 80 ℃, so just very easily deforms the pvc pipe road easily, thereby cause water from pipeline, to overflow, make troubles for people's life.
Summary of the invention
In order to solve the not enough problem that present pvc pipe exists, the invention provides a kind of high-temperature resistant low-noise drain pipe, this waste pipe not only can be realized drain function, and can use under hot environment for a long time, its noise is also lower in use simultaneously.
The present invention realizes by such mode: this high-temperature resistant low-noise drain pipe is made as internal layer, mesosphere and outer field three-decker, internal layer wherein and outer the employing with the atactic copolymerized polypropene are the composite material formation of main raw material, the mesosphere is the macromolecule packing, and wherein the recipe ratio of composite material is:
Atactic copolymerized polypropene 50-90%,
Auxiliary material 10-50%,
The charge ratio of macromolecule packing is:
Block copolymerization polypropylene 20-80%,
Silica 20-80%,
Oiling agent 0.3-2%,
Look female 0.5-5%.
Auxiliary material in the composite material is calcium carbonate and look mother's a mixture, and Masterbatch wherein is a titanium dioxide, and oiling agent is a stearic acid.Through practice, the preferred formulations ratio of internal layer and the outer composite material that is adopted is among the present invention:
Atactic copolymerized polypropene 50-90%,
Calcium carbonate 9-49%,
Look female 1-5%,
Integration testing high-temperature resistant low-noise drain pipe of the present invention and cast iron tube, PVC waste pipe are as follows in the parameters contrast of aspects such as noise, high temperature resistant, hygienic environment-protecting:
| Test event | Cast iron tube | The PVC waste pipe | High-temperature resistant low-noise drain pipe |
| Noise | 23 decibels | 35 decibels | 25 decibels |
| High temperature resistant | ??100℃ | ??70℃ | ??90℃ |
| Hygienic environment-protecting | Easily get rusty | Harmful materials such as leaded, barium | The material that not leaded, barium etc. is harmful and can not getting rusty |
Advantage of the present invention is: resistance to high temperature is stronger, has tangible noise reduction audio fruit, and harmful materials such as not leaded, barium help promoting the use in building field, and raw material that is added and production technology thereof are all simpler, and product cost is low.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Accompanying drawing 1 is a cross-sectional view of the present invention.
Code description among the figure: 1-skin; The 2-mesosphere; The 3-internal layer.
Embodiment
As shown in Figure 1, the present invention is by being designed to waste pipe skin (1), mesosphere (2) and internal layer (3) be three-decker altogether, skin wherein (1) and internal layer (3) are made up of atactic copolymerized polypropene and auxiliary material, and all adopt with the composite material of atactic copolymerized polypropene as main raw material, auxiliary material wherein is calcium carbonate and look mother, utilize the high temperature resistant property of atactic copolymerized polypropene that internal layer (3) is reached in the characteristic of using under hot environment for a long time, calcium carbonate and look mother can increase the shock resistance of internal layer (3) and outer (1), mesosphere (2) is the macromolecule packing, and it mainly acts on is to reduce the noise that produces when current pass.
Embodiment:
Its preferred formulations ratio of composite material that outer in the present invention (1) and internal layer (3) are adopted is:
Atactic copolymerized polypropene 76%,
Calcium carbonate 22%,
Look mother 2%,
Here it is pointed out that present embodiment only explains more excellent scheme wherein, in practice, the batching of its composite material all can make product reach high-temperature resistant low-noise effect preferably in following scope, that is:
Atactic copolymerized polypropene 50-90%,
Calcium carbonate 9-49%,
Look female 1-5%,
The charge ratio of the macromolecule packing that mesosphere (2) is adopted is:
Block copolymerization polypropylene 20-80%,
Silica 20-80%,
Oiling agent 0.3-2%,
Look female 0.5-5%,
The production principle of high-temperature resistant low-noise drain pipe of the present invention is identical with the principle that the production people produce the PVC waste pipe, production technology adopts the co-extrusion production technology, product is an integral one-step molding, and that the present invention has is anticorrosive, the remarkable characteristic of non-corrosive, pollution-free, high temperature resistant, low noise.
