The results showed that when the ratio of monomer to monomer was between 1: 1 and 1: 1.5, 3%, the reaction temperature is 82 ℃, the reaction time is 5h, the synthetic resin film, calcium ion stability, corrosion resistance is better.
And then KH550, KH560 for silicone modification, and synthetic resin on the film test. Experiments show that: modified with silicone, is conducive to acrylic resin film water resistance, heat resistance. When the amount of initiator is 3%, the reaction temperature is 82 ℃, the stirring speed is 150r / min-200r / min, the amount of organic silicon is 6%, the reaction time is 5 hours. The synthetic silicone modified acrylic resin has
better film Nature, corrosion resistance, hydrophobicity, greatly improving the shortcomings of water-based acrylic resin.
In the emulsion polymerization method, OP-10 was introduced, and the optimum dosage and ratio of the emulsion polymerization system were determined by analyzing the particle size of the acrylic acid synthesized by emulsion polymerization, the separation of calcium ions and the analysis of the film. : The pre-emulsion-seed emulsion polymerization process, the reaction temperature is 80 ℃, the amount of emulsifier is 3%,the amount of NaHCO3 is 0.3%, the ratio of OP-10 to SDBS is 2: 1, the particle size distribution is uniform, The best performance, the best film performance.
