本发明的有益效果是：The beneficial effects of the invention are:
环氧树脂中特有的环氧基、经基、醚键等活性基团的存在，赋予其许多优异性能。不仅密实、抗渗漏、抗水、强度高，而且具有良好的机械力学性能，粘结性、电性能优越，耐低温性能好，可以作为减摩涂层中优良的涂层粘结剂，但因其耐高温性能不佳，因此本发明中采用改性环氧树脂，改性环氧树脂具有粘结力强、耐化学试剂性能好等优点，且改性环氧能增强了涂层抵御水、离子渗入的能力，提高了涂层与金属基体间的结合力，从而提高涂层的防护能力，此外，还能增加涂层的强度、提高附着力、改善流变性能、降低成本；有机硅改性环氧树脂兼具有机硅材料和环氧树脂的优异性能，用有机硅改性环氧树脂即可降低环氧树脂的内应力又能增加耐高温性、韧性等性能；The presence of reactive groups such as epoxy groups, via groups, and ether bonds unique to epoxy resins imparts many excellent properties. It is not only dense, leak-resistant, water-resistant, high-strength, but also has good mechanical properties, excellent adhesion, electrical properties, low temperature resistance, and can be used as an excellent coating binder in anti-friction coatings, but Because of its poor high temperature resistance, the modified epoxy resin is used in the invention, and the modified epoxy resin has the advantages of strong adhesion and good chemical resistance, and the modified epoxy can enhance the coating against water. The ability of ions to penetrate, improve the bonding between the coating and the metal matrix, thereby improving the protective ability of the coating, in addition, increasing the strength of the coating, improving the adhesion, improving the rheological properties, and reducing the cost; The modified epoxy resin has the excellent properties of the silicone material and the epoxy resin, and the silicone modified epoxy resin can reduce the internal stress of the epoxy resin and increase the properties such as high temperature resistance and toughness;

When the methyltriethoxysilane monomer is added dropwise, the water in the reactor is excessive and the solvent is small. When the concentration of dibutyltin dilaurate is a few ten thousandths, the methyltriethoxysilane is rapidly hydrolyzed. Methyltriethoxysilane has a high degree of hydrolysis, and when the solvent cannot dissolve the silanol in time, it will form a gel rapidly. The "reverse drip" method is adopted to make the reaction easy to control, inhibit the formation of gel, and improve the stability of the system. Sex.

The hydration layer, thus the polymer emulsion has excellent stability, and the pre-emulsified semi-continuous seed emulsion polymerization process is also used in the process of preparing the styrene-acrylic latex, which can ensure the emulsion polymerization process is more stable, the copolymerization composition is more uniform, and at the same time effective Control the particle size and distribution of latex particles in the emulsion.
