[0002] The PVC processing aids in the prior art generally use acrylate linear high molecular polymers, which are methyl methacrylate-butyl acrylate copolymers. The copolymer particles have general fluidity and high cost.
Generally, PVC resin is about 7,000-9,000 yuan / ton, and the price of methyl methacrylate-butyl acrylate copolymer is 21,000-25,000 yuan / ton. The price is high, which increases the cost of PVC products produced, and the surface finish of PVC profiles prepared by this copolymer is also average.

Embodiment 1
[0015] 1500 kg of demineralized water, 900 kg of methyl methacrylate, 100 kg of butyl acrylate, 1 kg of potassium persulfate, 15 kg of sodium dodecylsulfonate, and 2 kg of nano-cerium dioxide.
[0016] Described copolymer preparation method is as follows:
[0017] Add a set amount of demineralized water into the glass-lined reactor, start stirring at a stirring speed of 75 rpm, add emulsifier, methyl methacrylate and butyl acrylate, close the reactor, and turn on the heating. When the temperature in the reactor When 65°C was reached, the initiator was added. When the temperature in the reactor starts to rise, the polymerization reaction in the reactor has already started, and at this time, the cooling water is turned on to cool down. When the temperature rises to the peak, no longer rises, and starts to drop, add nano-cerium dioxide into the kettle, and when the temperature continues to drop to 65°C, turn off the cooling water, and discharge the material when the temperature ...

Abstract
The invention relates to a nano-ceria-modified acrylate linear high-molecular polymer and a preparation method thereof. The invention belongs to the technical field of PVC processing auxiliary material. According to the invention, during a methyl methacrylate-butyl acrylate copolymerization process or a methyl methacrylate homopolymerization process, nano-ceria is added, such that the acrylate polymer is prepared. The weight ratio of methyl methacrylate to butyl acrylate is 5-100:95-0. The amount of nano-ceria used is 0.1-20% of the total weight of the polymerization monomer. According to the invention, nano-ceria is used for modifying the acrylate high-molecular polymer which is a processing type acrylate linear high-molecular polymer. The acrylate polymer has the advantages of low cost and good particle state fluidity. With the polymer, prepared PVC profile has high surface smoothness. The preparation method is simple and feasible, and is easy to implement.
Description
technical field [0001] The invention relates to a nanometer ceria-modified acrylate linear polymer and a preparation method, belonging to the technical field of PVC processing aids. Background technique [0002] The PVC processing aids in the prior art generally use acrylic ester linear polymers, which are methyl methacrylate-butyl acrylate copolymers, which have general fluidity and high cost in particle state. Generally, PVC resin is about 7,000-9,000 yuan / ton, and the price of methyl methacrylate-butyl acrylate copolymer is 21,000-25,000 yuan / ton. The price is relatively high, which increases the cost of PVC products produced, and the surface finish of PVC profiles prepared by using this copolymer is also average. Contents of the invention [0003] The object of the present invention is to provide a kind of nano ceria modified acrylate linear high molecular polymer and its preparation method. The cost of the acrylate polymer is low, and the particle state fluidity is g...
