Abstract
The invention discloses an environmentally friendly plastic tube and a preparation method thereof. The plastic tube is prepared through mixing raw materials consisting of a polyvinyl chloride resin, a Ca-Zn composite stabilizing agent, chlorinated polyethylene, calcium carbonate, an acrylate type impact modifier ACR, titanium dioxide, stearic acid, polyethylene wax, an ultraviolet ray absorbent, and a pigment according to certain weight parts, reacting, and heating molding. The preparation method has the advantages of simplicity and reasonable formula, and the preparative environmentally friendly plastic tube which has the advantages of good heat dispersion performance, good corrosion resistance, good high temperature resistance and good tension resistance, can be effectively applied to all industries.
Description
Technical field
The present invention relates to a kind of tubing, be specifically related to a kind of environment-friendly type plastic tubing and preparation method thereof.
Background technology
Plastic pipe is the chemical building material that high-tech is composited, and chemical building material is after steel, timber, cement, the fourth-largest class New Building Materials that the present age is emerging.In recent years, chemical building material has been obtained the rapid progress fast development in China, and especially being widely used of novel environment friendly plastics tubing, started the revolution of the alternative traditional construction material of a sound.Current losses is little, energy-conservation because having for plastic pipe, material-saving, protection are ecological, the advantage such as convenient of being completed, and is widely used at present the fields such as building water supply and drainage, cities and towns plumbing and gas line, becomes the main force of new millennium urban construction pipe network.
Plastics are different with traditional material, technical progress paces faster, the new technology, novel material, the novel process that constantly occur make the advantage of the relative traditional material of plastics tubing more and more outstanding.Plastic pipe is compared with cement pipe with traditional metal tube, have lightweight, general is only the 1/6-1/10 of metal tube, erosion resistance is preferably arranged, shock resistance and tensile strength, the plastics tubing internal surface more smooth than cast iron pipe many, frictional coefficient is little, fluid resistance is little, can reduce the water delivery energy consumption more than 5%, synthesis energy saving is good, manufactures the right reduction by 75% of energy consumption, convenient transportation, install simply, reach 30-50 work-ing life.Polyethylene tube is very fast in the countries in the world development over nearly 10 years, and developed country has accounted for absolute advantage in feedwater field and gas burning field using polythene pipe.Polyethylene tube not only is used for replacing traditional steel pipe, cast iron pipe etc. in a large number, is also replacing polyvinyl chloride pipe, and reason just is polyethylene tube technological innovation over nearly 10 years.Material has great progress on the one hand, and by the improvement of polyethylene polymerization production technique, the intensity of Polyethylene Pipe Resin has almost improved 1 times.Utilisation technology has new development on the other hand, for example need not excavate pipe trench in recent years, the technology that adopts the directional drilling method to lay polyethylene tube has been given full play to the superiority of polyethylene tube, makes traditional piping material be applicable to adopting the occasion of this method there is no competitive capacity at all.
