15-40 parts of butyl ester monomer, 5-30 parts of styrene monomer and 20-40 parts of methyl methacrylate monomer, styrene monomer and methyl
The gross mass of methyl acrylate is no more than the half of calcium maleate quality.
A kind of preparation method of the polyvinyl chloride forming agent, includes the following steps：
（1）Calcium maleate monomer, initiator, emulsifier are added in polymeric kettle, stirring is warming up to 40-80 DEG C, is slowly added to third
Olefin(e) acid butyl ester continues to stir 1-3h after being all added, obtains butyl polyacrylate-calcium maleate latex, is stratum nucleare；
（2）The mixed liquor for adding initiator, styrene monomer and methacrylate monomers continues to be warming up to 30- under stirring
50 DEG C, stirring 1-3h, then spray-dried polyvinyl chloride forming agent are further continued for after constant temperature.
Further, in the preparation method of the polyvinyl chloride forming agent, the initiator is potassium peroxydisulfate, persulfuric acid
One kind in ammonium, ammonium bisulfite, additive amount are the 0.01%-0.1% of calcium maleate monomer weight.
Further, in the preparation method of the polyvinyl chloride forming agent, the emulsifier is disproportionated rosin acid sodium, ten
One kind in sodium dialkyl sulfate, dodecyl sodium sulfate, additive amount are the 0.2%-2% of maleic anhydride monomer weight.
Forming agent provided by the invention can promote polyvinyl chloride that must be plasticized, and reduce its melt viscosity, reduce energy consumption and life
Produce cost；While improving PVC processing performances, the long-time stability of PVC product can be improved, price is less than ACR, reduces and adds
The cost of raw material of factory.
