Mix, mixing speed is 800 rad/ min, and mixing time is 2-3h；
After the completion of step 3, step 2, a certain amount of diallyl phthalate is added into batch mixer, and to stirring
Container is stirred, and mixing speed is 800 rad/ min, and mixing time is 20-30min, obtains mixed emulsion；
Step 4, with vacuum plant vacuum defoaming treatment is carried out to the mixed emulsion；
Step 5, to the mixed emulsion stewing process after above-mentioned defoaming treatment, and it is carried out to be preheated to 60 DEG C；
After the completion of step 6, preheating, mixed emulsion is put into banbury and carries out banburying；
After step 7, banburying terminate, sheet semi-finished product are made in calendering, are then cut semi-finished product according to designed size, i.e.,
Obtain high tenacity pvc material.
Further, in step 1, the mould inhibitor is nano titanium oxide, and the nano titanium oxide is rutile-type,
The heat stabilizer is barium zinc stabilizer, and the secondary plasticizer(-iser) is synthesis vegetable esters.
Further, in the step 4, temperature during vacuum froth breaking is 120 DEG C.
Further, by high tenacity pvc material made from above-mentioned preparation method by following parts by weight raw material system
Into：5 parts of haloflex, 6 parts of nanometer silica gel, 86 parts of Corvic, 12 parts of precipitated calcium carbonate, 10 parts of calcium stearate is adjacent
5 parts of dially phthalate, 3 parts of MBS resins, 3 parts of silicon nitride nano particles, 6 parts of boron fibre, 2 parts of mould inhibitor is thermally-stabilised

In the preparation process in accordance with the present invention, eliminate high-temperature mixing and the process rapidly cooled down, thus save heating and
Big energy required for cooling, so that cost is reduced, in addition, in production process, the process before extrusion is simplified,
This improves production efficiency.
In order to obtain high tenacity pvc material, in preparation process, silicon nitride nanopowder is added into batch mixing,
The wearability and intensity on floor can be greatly enhanced, and calcium stearate can play heat stabilization, and pvc material is machined with
Big effect, to colour stable, processes extruded velocity, the demoulding is helpful, can significantly improve pvc material Forming Quality；
There is boron fibre addition boron fibre in high intensity, high resiliency and resistant to elevated temperatures characteristic, pvc material it can be significantly increased
Intensity, is a kind of powerful reinforcing agent of performance, makes pvc material be difficult to be destroyed；Haloflex has excellent weather-proof
Property, resistance to ozone, chemical-resistant resistance and ageing-resistant performance, with good oil resistivity, anti-flammability and tinctorial property, with other high scores
Sub- material, which has in good compatibility, pvc material, adds haloflex, can improve the items of pvc material
Performance, makes pvc material toughness good, can preferably give play to the effect of its high resiliency.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：By add specific components and
Change the proportional quantity of each component, make pvc material while meeting with good mechanical performance, make polyvinyl chloride material
Material possesses high tenacity, improves its survivability, and then reaches long-lived purpose, while optimizing preparation technology, makes to be made
Pvc material performance it is more preferable.
