| titleOfInvention | Preparation method of alkynyl polyether modified organic silicon surfactant |
| abstract | The invention belongs to the field of chemical industry, and provides a preparation method of alkynyl polyether organic silicon surfactant. Compared with the prior art, the alkynyl polyether modified organic silicon surfactant can be prepared from cheap phenylalkyne, an epoxy compound and low-hydrogen polysiloxane in one step, and is simpler in formula, more convenient to operate, green, safe, efficient, environment-friendly and suitable for industrial production. And the prepared organosilicon surfactant is applied to rigid polyurethane foam, and shows more excellent physical properties. |
