Problems solved by technology

[0003] Since SPPO molecules are extremely hydrophobic and contain hydrolyzable and cross-linked active organosilane oxygen end groups that are extremely sensitive to water, it is extremely difficult to make them water-based. So far, there have been no reports on water-based SPPO.

Abstract

The invention relates to a method for preparing active organosilicon end capping polypropylene oxide cationoid emulsion, which comprises the following steps: using hydrogen-containing polysiloxane, unsaturated polyether and epoxy-containing unsaturated compounds as main raw materials to prepare epoxy-containing polyether-polysiloxane by adopting two steps of silicon-hydrogen addition reaction and then prepare a series of quaternary ammonium salt type polyether-polysiloxane nonionic cationic surfactants with different molecular weights and different hydrophilic and oleophilic values through quaterisation, and then using the obtained surfactant to emulsify active organosilicon end capping polypropylene oxide (SPPO), so as to obtain the active organosilicon end capping polypropylene oxide cationoid emulsion containing no organic solvent and having good storage stability and freeze-thaw stability through phase inversion emulsifying process. The method has the advantages of little equipment investment, simple process, easy operation and low production cost; and the obtained active organosilicon end capping polypropylene oxide cationoid emulsion can be used as a basic material for producing environment-friendly water-based polymer products such as paint, adhesive and sealant.

Description

technical field [0001] The invention belongs to the technical field of macromolecules and fine chemicals, more specifically, the invention relates to a quaternary ammonium salt type polyether-polysiloxane nonionic cationic surfactant and a preparation method thereof, and the use of the quaternary ammonium salt type polyether-polysiloxane nonionic cationic surfactant An active silicone-terminated polypropylene oxide cationic emulsion obtained from a polyether-polysiloxane nonionic cationic surfactant and a preparation method thereof. Background technique [0002] As an important basic polymer, reactive organosiloxane-terminated polypropylene oxide (SPPO) has attracted widespread attention in recent years, and has been rapidly developed in the fields of construction and sealing. [0003] Since SPPO molecules are extremely hydrophobic and contain hydrolyzable and cross-linked active organosilane oxygen end groups that are extremely sensitive to water, it is extremely difficult ...
