Abstract
Description
A stable organosilicon emulsion and its preparation method Technical Field
[0001] This invention relates to a stable organosilicon emulsion and its preparation method, belonging to the field of organic synthesis technology. Background Technology
[0002] Organosilicon is a new type of polymer material. Compared with other polymer materials, organosilicon materials have excellent temperature resistance, weather resistance, and electrical insulation properties. They also have low surface tension and low surface energy, so they have a wide range of applications.
[0003] Organosilicon emulsions are among the most common organosilicon products, primarily composed of organosilicon, water, and surfactants. Due to their unique properties, they are widely used in industry. Organosilicon emulsions can be classified into oil-in-water emulsions and water-in-oil emulsions. Many methods exist for preparing organosilicon emulsions, but ensuring the preparation of stable emulsions that function effectively in their applications without causing adverse reactions places higher demands on their preparation and performance.
[0004] Patent CN201210571401.3 utilizes a spatially structured silicone polyether to disperse and emulsify a high-viscosity organosilicon composition, and improves the emulsion stability using a polyacrylate thickener; Patent CN202010253813.7 uses a compound emulsification system and a thickener to prepare an organosilicon emulsion; and CN202111516457.4 uses siloxane with an acrylic copolymer, a block wetting agent, a polyether, inorganic particles, an emulsifier, and water to prepare an organosilicon emulsion with good low surface properties and compatibility. Patent CN201210560280.2 introduces a high-temperature silicone composition to improve the low surface tension properties of silicone emulsions. At the same time, it uses synthesized polyether-modified polysiloxane to encapsulate the emulsified silicone composition, thereby improving the dispersibility and stability of the emulsion. CN102718978A discloses a method for reducing the viscosity of silicone emulsions. By first compounding silicone polyether, organic solvent and water, and then using them as a diluent in the preparation process of silicone emulsions, the viscosity of the resulting silicone emulsion is greatly reduced due to the emulsifying and defoaming effects of silicone polyether and the dispersing effect of organic solvent, and it can be quickly dispersed in foaming systems.
[0005] Regarding emulsifiers, the above patents improve emulsification performance by introducing unsaturated polyether-modified silicone polyethers, dispersants, or co-emulsifiers, or by reducing the viscosity of organosilicon actives to improve the dispersion performance of the emulsion, ultimately preparing a stable organosilicon emulsion. Summary of the Invention
[0006] The key technology of this invention is the introduction of polyglycerol ricinoleate with different degrees of polymerization, polydiol oleate with different molecular weights, and silicone polyether to improve the emulsifying ability and stability of the emulsion. Polyglycerol ricinoleate, as an emulsifier and stabilizer, can disperse water-soluble and oil-soluble substances, making the components mix evenly and emulsify more fully, thereby improving the stability of the emulsion. This invention uses a high-speed emulsification pump for emulsification, resulting in smaller emulsion particle size and better stability.
