Abstract

The invention belongs to the field of amino silicon oil, and discloses a preparation method of a high-temperature-resistant alkali type amino silicon oil emulsion, which comprises the following steps:S1, preparing 40-50 parts of amino silicon oil, 10-20 parts of an emulsifier, 35-40 parts of deionized water, 5-10 parts of a glycerol additive and 3-6 parts of trifluoromethyl maleic anhydride for later use; S2, adding an emulsifier into the high-shear emulsifying kettle, and starting to stir. According to the invention, trifluoromethyl maleic anhydride can be amidated with amino silicone oil, amino active hydrogen in the amino silicon oil structure is reduced and carboxyl is increased; therefore, the effect of reducing emulsion yellowing is achieved; the high temperature resistance and thealkali resistance of the amino silicon oil emulsion are improved; meanwhile, the emulsifier can improve the surface tension among various constituent phases in the emulsion, so that a uniform and stable dispersion system or emulsion substance is formed, the amino silicone oil emulsion has excellent stability, and the problems that the traditional amino silicone oil emulsion is easy to yellow and demulsify and poor in high-temperature resistance and alkali resistance are solved.

Description

technical field [0001] The invention relates to the technical field of amino silicone oil emulsion, in particular to a method for preparing a high temperature resistant alkali type amino silicone oil emulsion. 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 fi...
