Hydroxyl polyether-terminated polydimethylsiloxane and blue light emulsion of hydroxyl polyether-terminated polydimethylsiloxane as well as preparation method of blue light emulsion

Abstract

The invention discloses hydroxyl polyether-terminated polydimethylsiloxane and a blue light emulsion of hydroxyl polyether-terminated polydimethylsiloxane as well as a preparation method of the blue light emulsion. The blue light emulsion of hydroxyl polyether-terminated polydimethylsiloxane has a function of enabling a base material to be anti-sticky, dry and smooth, which is the same as the functions of conventional negative ion, positive ion and nonionic hydroxyl silicone oil emulsions. Different from the conventional negative ion, positive ion and nonionic hydroxyl silicone oil emulsions, the blue light emulsion of hydroxyl polyether-terminated polydimethylsiloxane has the characteristics that the water diluent (the solid content is 0.5-5%) of the blue light emulsion and the blending diluent (the solid content is 0.5-5%) formed by the blue light emulsion and an amino silicon oil emulsion at random ratio are highly stable; when the blue light emulsion is placed for a long time (above 90 days), the blue light emulsion does not layer and has no floating oil or oil spots; the blue light emulsion does not contain any thickening agent and can realize high solid content (the solid content convenient for use can reach 50%); as the blue light emulsion belongs to a non-ionic type, the wide compatibility can also be realized.

Description

technical field

[0001] The invention relates to a modified polydimethylsiloxane emulsion, in particular to a dilute stable hydroxyl polyether-terminated polydimethylsiloxane, the blue light emulsion and the blue light emulsion prepared by using the siloxane The preparation method belongs to the field of organic silicon chemical new materials. Background technique

[0002] Hydroxyl-terminated polydimethylsiloxane emulsions are currently mainly divided into anionic hydroxyl silicone oil emulsion (commonly known as anionic hydroxyl emulsion) and cationic hydroxyl silicone oil emulsion (commonly known as cationic hydroxyl emulsion); the anionic hydroxyl emulsion synthesized by the prior art is based on ten Dialkylbenzenesulfonic acid is used as a catalyst and emulsifier, and it is obtained by emulsion polymerization and telomerization of organosilicon rings in water. The solid content of the obtained emulsion usually does not exceed 30%, otherwise it is difficult to obtain, and ...
