Problems solved by technology

[0004] It is usually difficult to emulsify high-viscosity amino silicone oil, and it is necessary to add a large amount of emulsifier. The existing emulsion preparation method generally adopts the mechanical emulsification method, and a long period of stirring and dispersion is required to form a uniform emulsion. The emulsion usually has poor particle size dispersion and is unstable, especially during high-temperature storage, it is prone to demulsification, oil floating, and delamination.

Abstract

The invention discloses an amino silicone oil emulsion. The amino silicone oil emulsion comprises, by mass, 42-58% of amino silicone oil, 31-47% of deionized water, 6-10% of a surfactant, 3-1.1% of distearyl phosphatidyl glycerol and 0.5-5% of a pH adjuster. The surfactant comprises, by mass, 10-30% of polyethylene glycol 4000 monooleate, 40-60% of polyoxyethylene sorbitan monolaurate and 20-40% of cocamidopropyl betaine. The viscosity of the amino silicone oil is 2000-15000 mPa.s. The ammonia value is 0.2 to 0.8. The pH of the amino silicone oil emulsion is 6.5 to 7.0. The amino silicone oilemulsion is prepared from glass beads through a double-center mixing disperser, has high content of silicone oil, small particle size distribution and good storage stability and can be used in fabrictreatment.

Description

technical field [0001] The invention belongs to the technical field of silicone oil emulsion, and in particular relates to an amino silicone oil emulsion and a preparation method thereof. Background technique [0002] Silicone oil is a colorless, odorless, non-toxic and non-irritating liquid with good chemical stability, heat and cold resistance, weather resistance, hydrophobicity, lubricity, high refractive index and low surface tension. After emulsifying silicone oil to make silicone oil emulsion, it can be widely used in personal care products, textiles, and surface treatment. [0003] The amino group in the amino silicone oil can interact with the hydroxyl and carboxyl groups on the surface of the fiber, and is firmly adsorbed on the fiber to improve the washing resistance of the fabric; the amino silicone oil forms a film on the surface of the fabric. Generally speaking, the greater the molecular weight of the amino silicone oil, The better the film-forming property of...
