Coating formulation: basic formula of silicone acrylic emulsion

The core tip: Although acrylic resin has good weather resistance and light retention, and can be cured at room temperature, but due to its thermoplastic limit, it has poor heat resistance and is easy to stick and dust at high temperature, and brittle at low temperature The molecular structure of silicone resin is close to that of silicate, which is a typical organic-inorganic polymer, which determines its good light retention, weather resistance, water resistance, pollution resistance, chemical resistance and good flexibility However, it can not dry itself at room temperature, which greatly limits its use in building exterior wall coating Organosilicon is introduced into the main chain or side chain of acrylic acid to prepare Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: Although acrylic resin has good weather resistance and light retention, and can be cured at room temperature, but due to its thermoplastic limit, it has poor heat resistance and is easy to stick and dust at high temperature, and brittle at low temperature The molecular structure of silicone resin is close to that of silicate, which is a typical organic-inorganic polymer, which determines its good light retention, weather resistance, water resistance, pollution resistance, chemical resistance and good flexibility However, it can not dry itself at room temperature, which greatly limits its use in building exterior wall coating Organosilicon acrylic emulsion was prepared by introducing organosilicon onto the main chain or side chain of acrylic acid The basic formula of silicone acrylic emulsion is introduced in this paper (Table 1) A simple pre polymerization process is used to introduce organosilicon into the main chain or side chain of acrylic acid through chemical bonds, and prepare silicone acrylic emulsion with excellent properties Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
