The invention provides an
acrylate assistant for PVC (
polyvinyl chloride) and a preparation method of the
acrylate assistant, and belongs to the technical field of
acrylate assistants. The preparation method comprises the steps of nano
montmorillonite functionalization, synthesis of a core layer, synthesis of a middle layer and synthesis of a shell layer. The synthesis step of the core layer comprises the following steps: adding a core layer
emulsion into a reaction kettle, adding an
ammonium persulfate solution for the first time, heating to 64-68 DEG C, adding an
ammonium persulfate solution for the second time, and reacting for 48-55 minutes to obtain a functionalized core
emulsion; the core layer
emulsion is prepared from deionized water, functionalized nano
montmorillonite,
sodium allyloxy hydroxypropyl
sulfonate,
butyl acrylate, 2-ethylhexyl acrylate, hydroxyethyl methylacrylate and gamma-methacryloyloxypropyltrimethoxysilane through ultrasonic treatment, and the core layer emulsion is prepared from the deionized water, the functionalized nano
montmorillonite, the
sodium allyloxy hydroxypropyl
sulfonate, the
butyl acrylate, the 2-ethylhexyl acrylate, the hydroxyethyl methylacrylate and the gamma-methacryloyloxypropyltrimethoxysilane through ultrasonic treatment; the prepared acrylate auxiliary agent is used in PVC, the fluidity can be improved, and meanwhile the
impact resistance, the strength performance and the high-temperature stability performance are enhanced.
