Description
Technical field
The present invention relates to plastic pipe technical field, be specifically related to a kind of super-strong and super-toughened high temperature resistant polychloroethylene pipes and preparation technology thereof.
Background technology
Along with country's greatly developing power industry, Plastic power pipe is adopted to get more and more in the market, particularly in the paving mode of digging type power pipe, the power pipe of what major part adopted is pvc material.Compared with polyethylene electric power tubing, polyvinyl chloride is comparatively large because of Young's modulus, therefore has good intensity and shock resistance, and compared with PP tubing, polyvinyl chloride has good low temperature resistant fragility and ultimate compression strength.Although the part of properties of chlorinated polyvinyl chloride is better than polyvinyl chloride, because the cost of chlorinated polyvinyl chloride is far away higher than polyvinyl chloride, therefore polyvinyl chloride has very large potentiality in power pipe.But current polychloroethylene pipes, because intensity is relatively low, toughness is relatively poor, resistance to elevated temperatures is bad and shock resistance is not good enough, when be applied to as power pipe need bear high pressure, high temperature environment time, often because performance reason causes work-ing life shorter.Therefore, a kind of have high-strength, high-ductility, corrosion-resistant, high temperature resistant and the application of the polychloroethylene pipes of advantage of lower cost on power pipe has very important impact.
An application number is the patent of invention of 201110082741.5, disclose a kind of polychloroethylene pipes, be made up of following component: polyvinyl chloride resin 35 ~ 45%, one package stabilizer 1 ~ 5%, stearic acid 0.1 ~ 0.5%, acrylic elastomer-72 ~ 5%, titanium dioxide 0.5 ~ 1%, paraffin 0.1 ~ 1%, whitening agent 10 ~ 20% and light calcium carbonate 35 ~ 45%.This polychloroethylene pipes intensity is low, poor toughness, resistance to elevated temperatures are bad and shock resistance is not good enough, can not meet the construction needs of power pipe.
Summary of the invention
One object of the present invention provides a kind of super-strong and super-toughened high temperature resistant polychloroethylene pipes, with solve be applied to power pipe at present polychloroethylene pipes exist intensity relatively low, toughness is relatively poor, resistance to elevated temperatures is bad and shock resistance not good enough can not meet construction needs problem, simultaneously also modification carried out to tubing, make it have durable, prevent from going mouldy and the function of radiation-resistant glass.
Another object of the present invention is to provide the preparation technology of super-strong and super-toughened high temperature resistant polychloroethylene pipes.
In order to reach foregoing invention object, the present invention by the following technical solutions:
A kind of super-strong and super-toughened high temperature resistant polychloroethylene pipes, the raw material of described super-strong and super-toughened high temperature resistant polychloroethylene pipes comprises each component of following parts by weight: polyvinyl chloride 50-65 part, chlorinated polyvinyl chloride 25-38 part, anti-impact agent 12-18 part, weighting agent 4-10 part, stablizer 3-8 part, softening agent 2-5 part, external lubricant 0.1-0.6 part, internal lubricant 0.1-0.6 part and properties-correcting agent 3-7 part.Various auxiliary agent all has certain consistency with polyvinyl chloride resin, and the degree of crystallinity of PVC can be made to increase, and makes the molecular chain of PVC crystallization phases in mixed system be flat serrations shape configuration.Stablizer in formula system and modifier, increase the stability of the Molecular connectivity indices of PVC amorphous phase, so its over-all properties improves greatly.
Preferably, described anti-impact agent is MBS resin, and weighting agent is the calcium carbonate superfine powder of median size≤0.05 μm, and stablizer is calcium stearate.MBS resin has typical nucleocapsid structure, and because its solubility parameters is close with PVC, therefore both thermodynamic compatibilities are good, makes PVC have very high resistance to impact shock under room temperature or low temperature by the combination of MBS resin and PVC.The mixing of a small amount of calcium carbonate superfine powder can be combined with MBS, better can improve shock resistance.
Preferably, described softening agent is dioctyl phthalate (DOP), and external lubricant is higher fatty acid, and internal lubricant is high fatty alcohol, and properties-correcting agent is ACR401.The higher fatty acid lauric acid of external lubricant, the high fatty alcohol of internal lubricant is stearyl alcohol.Properties-correcting agent auxiliary agent improve the processing characteristics of resin with the use of being conducive to, improve the rheological property of resin, the melt mechanical property be conducive under thermo-elasticity state improves, and makes the performance of resin reach best requirement.
Preferably, the raw material of described super-strong and super-toughened high temperature resistant polychloroethylene pipes also comprises Chlorinated Polypropylene III, the epoxy resin of 1-4 part and the maleic anhydride inoculated polypropylene of 2-4 part that parts by weight are 2-10 part.Chlorinated Polypropylene III can have good two-phase interface consistency with chlorinated polyvinyl chloride and polyvinyl chloride, and can improve tensile strength and unnotched impact strength.Epoxy resin is epoxy resin E51, it is corrosion-resistant, insulation and intensity is higher, in this amount ranges, along with the interpolation of epoxy resin E51 consumption, the notched Izod impact strength of sample, tensile strength, elongation at break, vicat softening temperature are all effectively increased, but when consumption is excessive, properties there will be downtrending.Maleic anhydride inoculated polypropylene can become the bridge promoting polar material and non-polar material cementability and consistency, greatly can improve the affinity of filler and the dispersiveness of filler, therefore can the dispersion of reinforcing filler in system effectively, thus improve and stretch and shock strength.
Preferably, the raw material of described super-strong and super-toughened high temperature resistant polychloroethylene pipes also comprises the mould inhibitor that parts by weight are 1-5 part.Because tubing is needing buried in underground or be placed among sewer line for time in power pipe, rugged environment makes tubing easily go mouldy, and adds the fungicidal properties that mould inhibitor can improve tubing, thus increases its work-ing life.
Preferably, described mould inhibitor is copper sulfate.
Preferably, the raw material of described super-strong and super-toughened high temperature resistant polychloroethylene pipes also comprises the steel fiber that parts by weight are 1-5 part.Pipe applications is when power communication industry, because the power communication line in pipe can produce radiation and signal interference, add steel fiber in tubing after, these steel fibers can form wire netting on tube wall, thus there is radiation-resistant glass effect, reach the jamming-proof object of signal between each pipeline.
A preparation technology for super-strong and super-toughened high temperature resistant polychloroethylene pipes, specifically comprises the following steps:
