Abstract

The invention relates to a preparation method of a flame-retardant polyurethane foam material for an automotive interior, and belongs to the technical field of high polymer materials. The method comprises the step that by weight, 30-50 parts of oligomer polyhydric alcohols, 20-40 parts of polyisocyanates, 5-10 parts of brominated flame retardants, 5-15 parts of alumina sol, 3-6 parts of ethylene thiourea, 3-6 parts of N-Oleo sarcosine octadecyl amine, 3-5 parts of amine catalysts, 2-3 parts of organic tin catalysts, 2-4 parts of coupling agents, 5-10 parts of cross-linking agents, 1-5 parts of plasticizers, 1-5 parts of antioxidants and 90-130 parts of water are evenly mixed, then poured into a mold, heated, solidified and cooled. The flame-retardant polyurethane foam material for the automotive interior has the good mechanical performance, and the flame-retardant performance and the mechanical performance can be effectively improved by modifying the alumina sol and organic monomers.
