Abstract
The invention discloses an anti-aging polyethylene pipe which is prepared from, by weight, 70-78 parts of polyethylene resin, 5-12 parts of polyurethane rubber, 5-12 parts of nonylphenol polyoxyethylene ether, 3-5 parts of silicon dioxide, 2-4 parts of triphenyl phosphate, 2-6 parts of dimethyl phthalate, 3-7 parts of aluminum nitride, 2-6 parts of benzoic acid, 3-5 parts of dibasic lead phosphate, 3-7 parts of octyl stannum mercaptide and 6-9 parts of thermal-plastic polyurethane. The anti-aging polyethylene pipe is easy to manufacture, better in notch impact strength, tensile strength, bending strength, bending modulus and breaking elongation and longer in service life, and the anti-aging performance is better. Raw materials of the pipe are reasonably arranged, so that the overall strength and hardness of the material meet requirements, the anti-aging performance of the pipe is improved, and the pipe can better adapt to underground severe environments and is long in service life.
Description
Technical field
Present invention relates particularly to a kind of aging resistance polyvinyl piping materials.
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. Chemical building material achieves rapid progress fast development in China, especially the widely using of novel environment friendly plastics tubing, and has started a sound and has substituted the revolution of traditional construction material. Plastic pipe, because having the advantages such as current loss little, energy-conservation, material-saving, protecting ecology, completion is convenient, is widely used in the fields such as building water supply and drainage, cities and towns plumbing and Gas Pipe, becoming the main force of new century urban construction pipe network.
Plastic pipe is compared with the pipelines such as traditional cast iron pipe, coating steel pipe, pipe of cement, there is energy-saving material-saving, environmental protection, high-strength light, corrosion-resistant, inner wall smooth non-scaling, construction and the advantage such as maintenance simplicity, long service life, be widely used in building industry, municipal administration, industry and the agriculture fields such as building water supply and drainage, town and country plumbing, gas, electric power and cable jacket, industrial fluids conveying, agricultural irrigation.
Plastics are different with traditional material, technological progress paces faster, the new technique that constantly occurs, new material, new technology make the advantage of the relatively conventional material of plastic tube more and more prominent. Plastic pipe is compared with traditional metal tube and pipe of cement, have lightweight, it is typically only the 1/6-1/10 of metal tube, has good corrosion resistance, shock resistance and tensile strength, plastic tube inner surface more smooth than cast iron pipe many, coefficient of friction is little, fluid resistance is little, can reduce water delivery energy consumption more than 5%, synthesis energy saving is good, manufactures the right reduction by 75% of energy consumption, convenient transportation, installing simple, service life is up to 30-50. Plastic pipe develops quickly in countries in the world, and developed country applies at feedwater field and gas burning field that to have accounted for absolute advantage plastic pipe not only a large amount of for replacing traditional steel pipe, cast iron pipe etc., and reason is that technological innovation. Material has great progress on the one hand; On the other hand application technology has new development, makes traditional piping material not have competitiveness being suitable for the occasion adopted in this way at all. Also have a lot of new materials, new technique to study, or found out on probation examine to, it is possible to certainly, the technological progress of 10 years plastic tubes from now on will promote plastic tube more quickly to develop, more extensively.
China's plastic conduit develops quickly, and quality is improving constantly. At present, the plastic tube industry with polrvinyl chloride (PVC-U) pipe, polyethylene (PE) pipe and polypropylene (PP-R) Guan Weizhu has been preliminarily formed. Wherein polyethylene (PE) pipe protects sleeve pipe, industrial pipe, agricultural pipe etc. owing to the advantage of himself uniqueness is widely used in building water supply, construction drainage, buried drain pipe, building and heating, gas transmission and distribution, appendix, electrician and telecommunication. It is mainly used in urban water supply, city gas supply and field irrigation. PE, is polyethylene (english abbreviation of Polyethyleneofraisedtemperatureresistance), and the range of application of general PE tubing feedwater piping is the temperature lower than 40 DEG C, it is impossible to for delivery pipeline. PE tubing is a kind of degree of crystallinity thermoplastic resin high, nonpolar. The milky appearance of ortho states HDPE, is a degree of translucent in meagre cross section. PE has the characteristic of excellent resistance to great majority life and chemicals for industrial use.
The production technology of China's new material falls behind, and most equipment all needs import, adds the impact of external enterprise so that manufacturing enterprise of China faces the market test of sternness. But it is as various new material, new equipment and new technology constantly to emerge in large numbers, the plastic pipe promoting China towards diversification of varieties, customizations and is possessed multi-functional plastic pipe direction develops. Therefore, polyethylene (PE) pipe application constantly expands in recent years, but existing tubing ageing resistance is poor, and service life is short. Therefore it is modified on its basis, develops high ageing resistance, and meet the product of international standard, can largely expand its use field.
