Preferably, in S3, second material, the weight of first material ratio are 80-120：2-5.
The apparent density of gained igelite of the invention is high, and dry good fluidity, easily plasticizing, melt rheological property is good, and heat is steady
Qualitative height, there is larger industrializing implementation prospect.
In S1 of the present invention, using epoxidized soybean oil as raw material, end hydroxy butadiene is added under the cooperation of methacrylic acid
With reference to, the toughening effect of epoxidized soybean oil can be not only improved, and make to contain substantial amounts of double bond in product, activity is high；Gained first
On the one hand material can effectively be combined with polyvinyl chloride, nitrile silicone rubber, form more cross-linked structures, the intensity of reinforcing material
And vicat softening temperature, powdered whiting, gas phase titanium dioxide, flyash, bentonite, expanded graphite on the other hand can be promoted to exist
Disperse in polyvinyl chloride, mutual degree of scatter is high, and good fluidity, density is big, and heat endurance is good, storeroom interface bond strength
Height, the addition of polyvinyl chloride can be effectively reduced, reduces cost, be more beneficial for improving the mechanical property of polyvinyl chloride, have simultaneously
Have it is simple to operate, easily realize industrialized feature.
Polychloroethylene pipes obtained by the present invention are subjected to performance test：Its Mohs' hardness is 17 degree, and breaking strength is more than
18Mpa, elongation at break are more than 250%, and compression ratio is less than 28%；450 DEG C of hot blasts bake 2h, and its compressive resistance is 220 degree, is resisted
It is 75 degree to roll over intensity, wear extent 2.4g/cm3。
