Example Embodiment
[0025] Example 1A. Preparation of modified polymer emulsion (the amount used is parts by mass):
[0026] Adopt full acrylate polymerization method: use sodium dodecyl sulfate (SDS) and alkylphenol polyoxyethylene ether (OP-10) as a composite emulsifier, and the amount of sodium dodecyl sulfate (SDS) is 0.25 parts , The amount of alkylphenol polyoxyethylene ether (OP-10) is 0.55 parts, and the two emulsifiers are mixed in 25 parts of deionized water and heated to dissolve. Add the dissolved emulsifier solution into the reactor, stir and raise the temperature. Add 1.8 parts of methyl methacrylate (10% of the total amount) and 2.2 parts of butyl acrylate (10% of the total amount) into the reactor, increase the temperature to 75°C and add 13.8 parts of ammonium persulfate dissolved in deionized water 0.02 copies. Wait for the temperature to rise to 80°C and the monomer starts to be initiated. When the system is obviously "bluing", keep the reaction temperature at 80°C, and start addin...

[0038] Example 2A. Preparation of modified polymer emulsion (the amount used is parts by mass):
[0039] Adopt styrene-acrylate polymerization method: add 1.2 parts of MS-1 to 20 parts of deionized water, stir and raise the temperature, add 1.8 parts of styrene and 2.2 parts of butyl acrylate, heat up to 72℃ and add deionized water 18.3 parts of dissolved ammonium persulfate 0.06 parts, when the monomers are initiated to the beginning of the system "bluish", the temperature is maintained at about 75°C, and 15.8 parts of styrene and 20.2 parts of butyl acrylate each mixed with 0.2 parts of methacrylic acid are added dropwise. At the same time, 0.06 part of ammonium persulfate dissolved in 20 parts of deionized water was added dropwise. After the addition, the temperature was raised to 95°C, the reaction was continued for 0.5 hours, the temperature was lowered, and the material was discharged after stirring until it was cooled to room temperature. Modified polymer emulsion formula: ...

[0050] Example 3A. Preparation of modified polymer emulsion (the amount used is parts by mass)
[0051] Adopt full acrylate thermal polymerization method: use 0.42 parts of SDS and 0.84 parts of OP-10 as composite emulsifiers, mix these two emulsifiers in 11.2 parts of deionized water and heat to dissolve them. Add the dissolved emulsifier solution into the reactor, stir and raise the temperature. Add 1.8 parts of methyl methacrylate (9.5% of the total amount) and 2.3 parts of octyl acrylate (10% of the total amount) into the reactor, increase the temperature to 75°C and add 25 parts of ammonium persulfate dissolved in deionized water 0.063 parts. Wait for the temperature to rise to 80°C, the monomers begin to be triggered, and when the system is obviously "bluing", keep the reaction temperature at 80°C, and start to add 17.1 parts of methyl methacrylate (90.5% of the total amount) and octyl acrylate. 20.8 parts (90% of the total amount), 0.21 parts of methacrylic acid are mixed i...
