Description
Technical field
The present invention relates to a kind of plastic tube, particularly relate to the polyethylene pipe that a kind of intensity is higher.
Background technique
Plastic tube is generally with synthetic resin, and namely polyester is raw material, adds stabilizer, oiling agent, plasticizing agent etc., forms in tube producer with the method for " moulding " through extrusion process.Because it has light weight, corrosion-resistant, beautiful shape, without features such as bad smell, easy processing, easy constructions, obtains and apply more and more widely in construction engineering.Matched penetration pipe etc. installed by the main tap water supply system pipe arrangement as building construction, draining, exhaust and blowdown sanitary pipe, subsoil drain system, rain pipe and electric wire.Raising along with people's living standard, environmental consciousness and the concern to health, started the green revolution of a building material industry in plumbing field.Show according to a large amount of water monitoring data: after adopting 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 conventional metals 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, receive the favor of pipework circle and occupy considerable position, forming a kind of irresistible development trend.In the world the material of polyethylene pipe is divided into PE32, PE40, PE63, PE80, PE100 five grades, and for material mainly PE80 and PE100 of fuel tube and supply pipe.China does not have classification to Polyethylene Pipe Resin, and this makes domestic polyethylene gas pipe and supply pipe manufacturer select raw material more difficult, brings no small hidden danger also to the use of polyvinyl piping materials.Therefore National Bureau of Standards has done a large amount of revisions in GB/T13663-2000 new standard, define the intensity of pressure that different stage PE80 with PE100 of supply pipe is corresponding different, and the tensile strength performance removed in old plant, and add elongation at break (being greater than 350%), namely emphasize basic toughness.
Summary of the invention
The object of the present invention is to provide the polyethylene pipe that a kind of intensity is higher, have reliable and stable, intensity is higher and the advantage such as ageing-resistant.
Technological scheme of the present invention is: the polyethylene pipe that a kind of intensity is higher, the polyethylene pipe that described intensity is higher comprises the superiors, mesosphere and orlop, the described the superiors are high density polyethylene (HDPE)s, described mesosphere is tackiness agent, described orlop is rosin ester, described high density polyethylene (HDPE) accounts for the 61%-69% of the higher polyethylene pipe body weight of intensity, described tackiness agent accounts for the 11%-12% of the higher polyethylene pipe body weight of intensity, and described rosin ester accounts for the 17%-29% of the higher polyethylene pipe body weight of intensity.
In a preferred embodiment of the present invention, described tackiness agent is carboxymethyl cellulose.
In a preferred embodiment of the present invention, described high density polyethylene (HDPE) accounts for 67% of the higher polyethylene pipe body weight of intensity, described tackiness agent accounts for 11% of the higher polyethylene pipe body weight of intensity, and described rosin ester accounts for 22% of the higher polyethylene pipe body weight of intensity.
The polyethylene pipe that a kind of intensity of the present invention is higher, have reliable and stable, intensity is higher and the advantage such as ageing-resistant.
Accompanying drawing explanation
Accompanying drawing 1 be polyethylene pipe one preferred embodiment that intensity of the present invention is higher main TV structure schematic diagram.
In accompanying drawing, the mark of each parts is as follows: 1, the superiors, and 2, mesosphere, 3, orlop.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, Fig. 1 is the polyethylene pipe that a kind of intensity of the present invention is higher, and the polyethylene pipe that described intensity is higher comprises the superiors 1, mesosphere 2 and orlop 3, and the described the superiors 1 are high density polyethylene (HDPE)s, described mesosphere 2 is tackiness agents, and described orlop 3 is rosin esters.
Further illustrate, described tackiness agent is carboxymethyl cellulose, described high density polyethylene (HDPE) accounts for 67% of the higher polyethylene pipe body weight of intensity, and described tackiness agent accounts for 11% of the higher polyethylene pipe body weight of intensity, and described rosin ester accounts for 22% of the higher polyethylene pipe body weight of intensity.Described high density polyethylene (HDPE) is high, the nonpolar thermoplastic resin of a kind of degree of crystallinity.Translucent in meagre cross section in a certain degree.PE has excellent resistance to great majority life and the characteristic of chemicals for industrial use.The chemical product of some kind can produce chemical corrosion, such as corrosive oxidation agent (red fuming nitric acid (RFNA)), aromatic hydrocarbon (dimethylbenzene) and halogenated hydrocarbon (carbon tetrachloride).Non-hygroscopic and the steam-preventing had of this polymer, can be used for packing purposes.HDPE has good electrical property, and particularly dielectric strength is high, makes it be applicable to electric wire very much.In to high molecular weight grades, there is fabulous impact resistance.
Further illustrate, described carboxymethyl cellulose belongs to anionic cellulose ethers, and outward appearance is white or the wadding fibrous powder of micro-yellow or white powder, odorless tasteless, nontoxic; Be soluble in cold water or hot water, form the clear solution with certain viscosity.Solution is neutral or slight alkalinity, is insoluble to ethanol, ether, isopropanol, acetone and other organic solvent, dissolves in ethanol or the acetone soln of moisture 60%.Have hygroscopicity, stablize photo-thermal, viscosity with temperature raises and reduces.
Further illustrating, described rosin ester is the polyol ester of abietic acid, and conventional polyatomic alcohol polybasic alcohol has glycerine and pentaerythritol.Polylol abietate is lurid transparent solid, and softening point is at 90 ~ 110 DEG C, and acid number is 10 ~ 20.In order to painting, quality is slightly higher than the made person of rosin calcium soap.The softening point of rosin pentaerythritol ester, higher than esterase, makes the drying property after varnish, and hardness, the performance such as water-fast are better than the varnish that esterase is made.As the corresponding ester using newtrex or Hydrogenated rosin to make for raw material, variable color tendency reduces, and other performances also improve.The softening point of newtrex ester is higher than rosin ester, and the softening point of hydrogenated wood rosin glycerol ester then decreases.The polyethylene pipe that a kind of intensity of the present invention is higher, have reliable and stable, intensity is higher and the advantage such as ageing-resistant.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention, and the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
