Description
Technical field
The present invention relates to a kind of reinforced protective material for pipe and preparation method thereof, belong to pipe technology field.
Background technology
In the cost of plastic conduit engineering and energy consumption, lay link and usually occupy critical role.Non-excavation laying technology be substantially adopt non-excavation method pipeline laying to the underground line position requiring, most widely used in the trenchless technology of laying concrete pipe and steel pipe is pushing method, most widely used in the trenchless technology of laying plastics tubing is horizontal orientation boring laying method, because non-excavation laying need to draw in plastics tubing or advance in lowly getting out hole or old pipe to be repaired, in this process, tube surfaces can sustain damage unavoidably, probably directly touch sharp-pointed stone etc. and in tube wall, form point load, thereby damage high stress concentrations place, cause potential application risk, and common polythene tube surfaces is easier to scratch, during receptor site load, anti-cracking performance is also limited.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of reinforced protective material for pipe for above drawback, and the surface hardness that it can improve tubing make tubing in use be difficult for scratching, and anti-cracking performance is good, and its preparation method is provided.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A reinforced protective material for pipe, its moiety is counted as follows by weight:
Above-mentioned a kind of reinforced protective material for pipe, preferred, its moiety is counted as follows by weight:
The preparation method of above-mentioned a kind of reinforced protective material for pipe, its preparation method is as follows:
(1) copolymerization grade polypropylene, nano ceramics powder liquid, cold resistant plasticizer, coupling agent, strengthening agent and stablizer are added in stirrer and stirred, stirring velocity is 850-1000 rev/min, stirs 10-15 minute;
(2) mixture in step (1) is added in forcing machine and makes tubing, the temperature of extruder barrel is 125-155 ℃, and the temperature of mould is 156-175 ℃, and die temperature is 135-145 ℃.
Above-mentioned a kind of reinforced protective material for pipe and preparation method thereof, wherein, the preparation method of described nano ceramics powder liquid is: nano-ceramic powder is added in aqueous epoxy resin emulsion, stir, its stirring velocity is 550-650 rev/min, stir 5-10 minute, the weight ratio of nano-ceramic powder and aqueous epoxy resin emulsion is 11-15:100.
Above-mentioned a kind of reinforced protective material for pipe and preparation method thereof, wherein, described cold resistant plasticizer is epoxy soybean oil, trioctyl phosphate, epoxy stearic octyl ester mixes with the weight ratio of 1:2-3:3-4.
Above-mentioned a kind of reinforced protective material for pipe and preparation method thereof, wherein, described coupling agent is vinyl trichloro silane, calcium stearate mixes with the weight ratio of 1-1.5:1.
Above-mentioned a kind of reinforced protective material for pipe and preparation method thereof, wherein, described strengthening agent is sepiolite powder.
Above-mentioned a kind of reinforced protective material for pipe and preparation method thereof, wherein, described stablizer is extra light calcined magnesia.
Beneficial effect of the present invention is: nano ceramics powder liquid can obviously improve product hardness, it is even higher that hardness can reach 6-8H, because its nanometer particle size is quite tiny, therefore no matter be which kind of solvent is all transparent, sepiolite is a kind of Magnesium Silicate q-agent compound, its major ingredient is silicon-dioxide, and surface-area is large, because the surface of sepiolite is large and have silica group and silanol group, and there is filamentary structure desirable for arriving rubber agent effect, this protective material can increase the surface hardness of tubing greatly, than common tubing hardness, increased more than 3 times, significantly reduce the damage to tube surfaces in non-excavation laying, tubing can not scratched by the injustice place of sandstone or old tube wall in being applied to non-excavation laying process, even if be also not easy cracking while directly touching sharp-pointed stone, thereby increased security, extended work-ing life.
