Description
Technical field
The present invention relates to a kind of tubing, and in particular to a kind of high-performance PVC (polyvinyl chloride)-U formulating of recipe for pipes.
Background technology
Hard polvinyl choride pipe, be with Corvic and stabilizer, lubricant etc. after use pressure sintering extrusion forming,
It is the plastic pipe being developed and applied earliest.PVC-U pipes resistance to corrosion is strong, being easy to bonding, price, low, quality is hard, but
It is due to have PVC-U monomers and additive to ooze out, is only applicable in water supply system of the delivery temperature no more than 45 DEG C.In plumbing
It is widely used in engineering, from building plumbing system to one residential, city（Town）Water supply and sewerage pipeline, from low layer, multilayer
Building water supply and drainage is to skyscraper plumbing, from life plumbing to other water drainage-supply systems such as grey water system.
However, the popularization with PVC-U tubing in people live, the weak point of China's PVC-U tubing gradually exposes
Out.First, the environmental-protecting performance of PVC-U tubing is not good enough.PVC processing heat stabilities are poor, must be added to during its processing and forming hot steady
Determine agent, at present on the market in PVC-U tubing, using it is more be organic tin and lead salt type thermal stabilizing agent, wherein organotin belongs to
Heavy metal heat stabilizer, good thermal stability, itself toxicity is smaller, but be able to may also be produced in expensive and process
The noxious materials such as raw trimethyltin chloride, but also environment is endangered, huge especially is poisoned to aquatile；And lead salts is stable
Agent powder is tiny, along with dust suction body, being easily caused lead poisoning in dispensing and batch mixing, and produces PVC-U tubing meetings
Cause water and soil pollution.Therefore, most PVC-U tubing and unrealized environmental protection truly on the market, however it remains
Toxicity and the harm of pollution.Secondly the performance such as physical and mechanical property, heat resistance, weatherability of PVC-U tubing is not ideal.
Because PVC-U tubing walls are thin and rigidity is not so good as cast iron pipe and steel pipe, fragility is big, thus tubing transport, stack,
During construction and use, the phenomenon such as tend to deform, rupture and losing and use ability；Further, since PVC molecules
The presence of destabilizing factor in chain, when PVC-U tubing prolonged application is in open air, easily occurs photooxidation, thermo-oxidative ageing, and occurs
Xanthochromia, embrittlement, or even degraded, cause its actual life to reduce.Thus develop a kind of nontoxic, nothing for water supply and sewage work
Pollution, inexpensive, high performance PVC-U tubing are the key technologies solved the problems, such as.
The content of the invention
The present invention overcomes the deficiencies in the prior art, and technical problem to be solved is to provide a kind of strength character height, toughness
The high and low environmental type PVC-U tubing of cost.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of high-performance PVC (polyvinyl chloride)-U tubing, it is made by the component of following parts by weight：130-160 parts of polyvinyl chloride resin powder,
10-35 parts of fine particle calcium carbonate, 4.4-4.7 parts of calcium zinc stabilizer, 0.2-0.4 parts of titanium dioxide, 0.2-0.4 parts of stearic acid, PE waxes 0.7-1.2
Part, 0.01-0.03 parts of carbon black, 2-4 parts of toughener, 2-5 parts of impact modifier.
It is preferred that scheme it be to be made by the component of following parts by weight：150 parts of polyvinyl chloride resin powder, 30 parts of fine particle calcium carbonate,
4.6 parts of calcium zinc stabilizer, 0.3 part of titanium dioxide, 0.3 part of stearic acid, 0.8 part of PE waxes, 0.021 part of carbon black, 4 parts of toughener, anti-impact
3 parts of modifying agent.
More preferably scheme it be to be made by the component of following parts by weight：150 parts of polyvinyl chloride resin powder, fine particle calcium carbonate 10
It is part, 4.7 parts of calcium zinc stabilizer, 0.3 part of titanium dioxide, 0.3 part of stearic acid, 0.7 part of PE waxes, 0.021 part of carbon black, 2 parts of toughener, anti-
2 parts of impact modifier.
Optimal scheme it be to be made by the component of following parts by weight：150 parts of polyvinyl chloride resin powder, 25 parts of fine particle calcium carbonate,
4.5 parts of calcium zinc stabilizer, 0.3 part of titanium dioxide, 0.3 part of stearic acid, 1 part of PE waxes, 0.021 part of carbon black, 3 parts of toughener, anti-impact change
3 parts of agent of property.
The usage amount of fine particle calcium carbonate is increased in the formula of the present invention, manufacturing cost is reduced on the premise of quality is ensured；Together
When toughener and impact modifier are subjected to a certain proportion of compounding, while intensity is increased, raising toughness；It is steady using calcium zinc
Determine agent nontoxic, environmental protection.
The invention has the advantages that：In the production of PVC-U tubing, a kind of environmentally friendly organic calcium zinc is introduced stable
Agent, the other stabilizers being harmful to relative to conventional toxic not only eliminate PVC-U tubing and there may be and are detrimental to health and dirty
The hidden danger of environment is contaminated, and assigns the outstanding processing heat stability of material and mobility, production efficiency is effectively increased；In addition,
Toughener and impact modifier are carried out a certain proportion of compounding by the formula of offer simultaneously, effectively raise the intensity of finished product with
And toughness.
Each materials compatibility is good in the present invention, reduces the difficulty of processing of tubing, at the same property of raw material be effectively played,
On the premise of asepsis environment-protecting is ensured, high temperature resistant, the corrosion resistance characteristic of finished product are substantially increased, while good heat preservation performance, anti-oxidant
Property it is strong, surface smoothness is improved, and light weight, and easy transportation and installation, service life is extremely long.In the base of increase fine particle calcium carbonate filler
On plinth, production cost is reduced, so using of the present invention with the resources of production of enterprise can be greatlyd save, while PVC-
U tubing indices comply fully with national standard requirement.
