Abstract

The invention provides a preparation method of organic silicon modified polyether polyol. The preparation method comprises following steps: step one, preparing terminal hydrogen containing silicone oil; step two, preparing allyl polyether; and step three, preparing organic silicon modified polyether polyol. The preparation method has the advantages that the structural characteristics of common polyether polyol are maximally preserved; the speed of reactions between modified polyether polyol and isocyanate is similar with that of reactions between common polyether polyol and isocyanate; modified polyether polyol can completely or partially replace common polyether polyol; modified polyether polyol can be used with polyester polyol to synthesize polyurethane, moreover, the reaction process is mild and easily controllable, the synthesized polyurethane is used to paint a material, the coated material is smooth and has a good wear resistant performance, and no surface migration happens.

Description

technical field

[0001] The invention belongs to the field of polyether polyol manufacture, and in particular relates to a preparation method of organosilicon-modified polyether polyol. Background technique

[0002] Polyether polyol is the main raw material for the synthesis of polyurethane. Polyurethane is the abbreviation of polyurethane, which refers to a class of polymers containing carbamate groups in the main chain of macromolecules. Polyurethane is divided into two categories: polyester polyurethane and polyether polyurethane. For polyether polyurethane, due to the low cohesive energy and easy rotation of the ether bond in the molecular structure of the raw material polyether polyol, the polyurethane material prepared from it has good low-temperature flexibility and excellent hydrolysis resistance, and the raw material system has low viscosity and is easy to rotate. It is miscible with isocyanate and auxiliary components, and has excellent processing performance. ...
