Embodiment 1

[0031] Dissolve 44.44g of flame retardant in 177.7g of n-butanol, heat to 90°C with stirring, and slowly add 88.8g of epoxidized soybean oil with an epoxy value of 4.15mol / kg. After the addition was complete, the temperature of the reactants was raised to 105°C for 8 hours. After cooling to room temperature, the organic solvent is recovered by distillation to obtain a bio-based flame-retardant soybean oil polyol.

Embodiment 2

[0033] Dissolve 44.44g of flame retardant in 222.2g of tert-butanol, heat to 100°C under stirring, and slowly add 199.98g of a mixture of epoxidized soybean oil, epoxidized castor oil and epoxidized palm oil. After the addition was complete, the temperature of the reactants was raised to 105°C for 8 hours. After cooling to room temperature, the organic solvent is recovered by distillation to obtain a bio-based flame-retardant soybean oil polyol.

Embodiment 3

[0035] Dissolve 44.44g of flame retardant in a mixture of 266.64g of toluene and DMF, heat to 140°C with stirring, and slowly add 133.32g of epoxy castor oil with an epoxy value of 4.15mol / kg. After the addition was complete, the temperature of the reactants was raised to 105°C for 8 hours. After cooling to room temperature, the organic solvent is recovered by distillation to obtain a bio-based flame-retardant castor oil polyol.

Abstract

The invention provides biobased flame resistant polyol and a preparation method and application thereof and belongs to the field of flame resistant materials. By mixing epoxidized plant oil and a fire retardant and an organic solvent and reacting at 60-140 DEG C, the biobased flame resistant polyol is obtained. According to the biobased flame resistant polyol prepared by the reaction between the epoxidized plant oil and the fire retardant, a small amount of non-biological carbon atoms are introduced into the structure. The product belongs to a renewable resource and has biodegradation performance and meets the requirements of energy conservation and environmental protection. Meanwhile, by introducing the fire retardant element phosphorus, the product is made into a foamed material and the polyurethane foamed material also can be endowed with a certain flame retardant property.

Description

technical field [0001] The invention relates to the technical field of flame retardant materials, and in particular to a bio-based flame retardant polyol and its preparation method and application. Background technique [0002] Polyurethane foam has excellent physical and mechanical properties. It is the best insulating material in the world. It is also a good sound insulation material. It is an energy-saving and environmentally friendly material with a wide range of applications. [0003] Polyol is one of the main raw materials of polyurethane foam materials. At present, polyols used in polyurethane foam in China are mainly petroleum derivatives of non-renewable resources. Therefore, seeking efficient, environmentally friendly and renewable vegetable oils as alternative raw materials for the preparation of polyols has received attention. Epoxidized soybean oil, epoxidized castor oil and epoxidized palm oil are obtained by epoxidation of natural soybean oil, castor oil and ...
