(2) water and emulsifying agent are added into there-necked flask, stirring is opened, starts simultaneously at and be heated to 70 DEG C, leads to nitrogen after 40 minutes,
Add initiator；
(3) solution in step (1) constant pressure funnel is added drop-wise in the solution in the there-necked flask of step (2)；
(4) after being added dropwise, reaction finally gives quadripolymer latex after 4 hours.
Further, methacrylic acid, methyl methacrylate, acrylamide, ethyl acrylate four in the step (1)
The percentage that kind total monomer weight accounts for emulsion gross weight is 25%-35%.
Further, the weight of the ethyl acrylate accounts for the 40%-60% of four kinds of total monomer weights, methyl methacrylate

Further, the emulsifying agent in the step (2) is alkyl phenol ether sulfosuccinic acid ester sodium salt, octyl phenol polyoxy second
The compound of alkane 10 or both, the dosage of emulsifying agent are the 0.2%-0.6% of four kinds of total monomer weights.
Further, the initiator in the step (2) is potassium peroxydisulfate or ammonium persulfate, and the dosage of the initiator is
The 0.1%-0.3% of four kinds of total monomer weights.
A kind of quadripolymer latex, it is made by the preparation method of described quadripolymer latex.
After such scheme, quadripolymer latex of the present invention and preparation method thereof, mixed by the monomer of step (1)
Quadripolymer latex of the present invention is made in process and step (2), (3), the polymerisation process of (4), and it is with methacrylic acid, first
Base methyl acrylate, acrylamide and ethyl acrylate are raw material, and a kind of anionic metering system is obtained by emulsion polymerization
Acid-methyl methacrylate-acrylamide and acrylic acid methacrylate copolymers emulsion, oil-contaminated water of oil field oil-water separating agent, the invention
Oil-water separating agent there is good oil-water separation for oil-contaminated water of oil field.
