Abstract

The invention discloses plant oil polyol containing phosphorus and nitrogen as well as a preparation method and application of the plant oil polyol. The preparation method of the plant oil polyol containing phosphorus and nitrogen comprises the following steps: 1) mixing epoxidized soybean oil, 9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide and an acidic/basic catalyst, and carrying out a reaction so as to obtain the plant oil polyol containing phosphorus; and 2) mixing the phosphorus-containing vegetable oil polyol with an amine compound, and reacting to obtain the phosphorus-nitrogen-containing vegetable oil polyol. The plant oil polyol containing phosphorus and nitrogen simultaneously contains two elements P and N with a synergistic flame retardant effect, is high in flame retardant efficiency, does not have a flame retardant precipitation phenomenon when being used for a polyurethane product, and does not influence the physical properties of the polyurethane product.

Description

technical field [0001] The invention relates to the technical field of organic synthesis, in particular to a phosphorus-nitrogen-containing vegetable oil polyol and a preparation method and application thereof. Background technique [0002] Rigid polyurethane foam, referred to as rigid polyurethane foam, is mostly closed-cell structure, which has excellent characteristics such as good heat insulation effect, light weight, high specific strength, and convenient construction. It also has sound insulation, shockproof, electrical insulation, heat resistance, cold resistance, Solvent resistance and other characteristics, widely used as insulation materials for refrigerators, cold storage, refrigerated trucks, etc., as well as insulation materials for buildings, storage tanks, pipelines, etc. However, rigid polyurethane foam is flammable, and a large amount of toxic and harmful smoke and gas will be produced during combustion, which greatly limits its application range. At presen...
