The invention discloses a PVC (polyvinyl chloride) plastic tube long in service life. The PVC plastic tube long in service life comprises an uppermost layer, a middle layer and a lowermost layer. The uppermost layer is made of polyvinyl chloride, the middle layer is made of polyester, the lowermost layer is made of phthalate, the polyvinyl chloride accounts for 11%-24% of the weight of a PVC plastic tube body long in service life, the polyester accounts for 31%-40% of the weight of the PVC plastic tube body long in service life, and the phthalate accounts for 40%-51% of the weight of the PVC plastic tube body long in service life. The PVC plastic tube long in service life has the advantages of light weight, long service life, high strength and the like.
Description
Technical field
The present invention relates to a kind of plastic tube, relate in particular to a kind of PVC plastic tube of long service life.
Background technique
Plastic tube is generally with synthetic resin, and namely polyester is raw material, adds stabilizer, oiling agent, plasticizing agent etc., with the method for " moulding ", in tube producer, through extrusion process, forms.Due to it there is light weight, corrosion-resistant, beautiful shape, without features such as bad smell, easy processing, easy constructions, in construction engineering, obtained application more and more widely.Main tap water supply system pipe arrangement, draining, exhaust and blowdown sanitary pipe, subsoil drain system, rain pipe and electric wire as building construction installed matched penetration pipe etc.Along with the raising of people's living standard, environmental consciousness and to healthy concern, in plumbing field, started the green revolution of a building material industry.According to a large amount of water monitoring datas, show: adopt after cold galvanizing steel pipe, general working life, iron taste was serious less than 5 years with regard to corrosion.Resident complains to government department one after another, causes a kind of social concern.Plastic tube is compared with traditional metal pipeline, have from heavy and light, corrosion-resistant, compressive strength is high, safe and sanitary, resistance to water-flow are little, energy saving, saving metal, better people's living environment, long service life, the feature such as easy for installation, be subject to the favor of pipework circle and occupied considerable position, having formed a kind of irresistible development trend.
Summary of the invention
The object of the present invention is to provide a kind of PVC plastic tube of long service life, there is lightweight, long service life, intensity compared with advantages of higher.
Technological scheme of the present invention is: a kind of PVC plastic tube of long service life, the PVC plastic tube of described long service life comprises the superiors, mesosphere and orlop, the described the superiors are PVC＝polyvinyl chloride, described mesosphere is polyester, described orlop is phthalic acid ester, described PVC＝polyvinyl chloride accounts for the 11%-24% of the PVC plastic tube body weight of long service life, described polyester accounts for the 31%-40% of the PVC plastic tube body weight of long service life, and described phthalic acid ester accounts for the 40%-51% of the PVC plastic tube body weight of long service life.
In a preferred embodiment of the present invention, described polyester comprises polyethylene terephthalate, polybutylene terephthalate, polyarylate and polyester elastomer.
In a preferred embodiment of the present invention, described PVC＝polyvinyl chloride account for long service life PVC plastic tube body weight 14%, described polyester account for long service life PVC plastic tube body weight 37%, described phthalic acid ester account for long service life PVC plastic tube body weight 49%.
The PVC plastic tube of a kind of long service life of the present invention, has lightweight, long service life, intensity compared with advantages of higher.
Accompanying drawing explanation
PVC plastic tube one preferred embodiment that accompanying drawing 1 is long service life of the present invention main TV structure schematic diagram.
In accompanying drawing, the mark of each parts is as follows: 1, the superiors, 2, mesosphere, 3, orlop.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, Fig. 1 is the PVC plastic tube of a kind of long service life of the present invention, and the PVC plastic tube of described long service life comprises the superiors 1, mesosphere 2 and orlop 3, and the described the superiors 1 are PVC＝polyvinyl chloride, described mesosphere 2 is polyester, and described orlop 3 is phthalic acid esters.
Further illustrate, described polyester comprises polyethylene terephthalate, polybutylene terephthalate, polyarylate and polyester elastomer, described PVC＝polyvinyl chloride account for long service life PVC plastic tube body weight 14%, described polyester account for long service life PVC plastic tube body weight 37%, described phthalic acid ester account for long service life PVC plastic tube body weight 49%.Described PVC＝polyvinyl chloride material is very light, and carrying, handling, construction facility, save artificial.Chemical resistance is good, and flow resistance is little, and the wall of pvc pipe is smooth, and fluid resistance is little, and its roughness coefficient only 0.009, is low compared with other tubing, and under identical flow, caliber can dwindle, and mechanical strength is large, and electric insulating quality is good, does not affect water quality.
Further illustrate, described polyester has good combination property, 36～49 ℃ of vitrification points, 220～225 ℃ of fusing points.Low temperature crystallization speed is fast, formability good.Aspect mechanical property and heat resistance, though not as polyoxymethylene and polyamide, after strengthening with glass fibre, its mechanical property and resistance to heat are showing and are improving, tensile strength 135MPa, heat distortion temperature is (load 186MPa) up to 210 ℃, surpasses the nylon that glass fibre strengthens; Its moisture absorption is minimum in engineering plastics.Product size good stability, and easily make the type of resistance to combustion kind, price is also lower.
Further illustrating, described phthalic acid ester makes PVC＝polyvinyl chloride become resilient plastic cement from hard plastic glue, plays the effect of plasticizing agent.The PVC plastic tube of a kind of long service life of the present invention, has lightweight, long service life, intensity compared with advantages of higher.
The specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
