Abstract

The invention discloses bio-based flame-retardant polyether polyol and a preparation method thereof, and particularly relates to the technical field of organic high-molecular compounds. The bio-based flame-retardant polyether polyol comprises ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol, butanediol, nano magnesium hydroxide, nano cerium oxide, nano tin antimony oxide and corn starch. According to the invention, the contact combination effect of nano magnesium hydroxide, nano cerium oxide, nano tin antimony oxide and corn starch can be effectively enhanced, and meanwhile, the corn starch is subjected to modification treatment, so that the performance of the corn starch is improved. Mixing crushing treatment is performed in an ultramicro jet mill, various modified corn starch is adopted as a bio-based material to form the bio-based flame-retardant polyether polyol, such that the contact combination effect of the bio-based material and the polyol can be further improved, the dissociation resistance effect is good, the flame retardant property is ensured, and the produced polyurethane foam plastic has characteristics of stable structure and better wear resistance, and the flame retardant property of the produced polyurethane foam plastic is better.

Description

technical field [0001] The invention relates to the technical field of organic polymer compounds, more specifically, the invention relates to a bio-based flame-retardant polyether polyol and a preparation method thereof. Background technique [0002] Flame retardant polyether polyol, which is a halogenated polyether polyol, similar to flame retardant polyether, has medium viscosity, and has good compatibility with polyether and polyester polyols, because the flame retardant elements are combined into the polymer Medium, with long-lasting flame retardant effect. Flame-retardant polyether polyol has the characteristics of high strength, good dimensional stability, low thermal conductivity, strong adhesion, high output rate, and permanent flame retardancy. It is widely used in the production of polyurethane foams such as high flame-retardant spray coatings and panels. Bio-based mainly refers to lignocellulosic agricultural and forestry wastes such as straws other than grain. ...
