Abstract

The invention discloses an eco-friendly flame-retardant polyurethane foaming material for a cab deflector cover and a preparation method thereof. The eco-friendly flame-retardant polyurethane foaming material comprises an acetonitrile polyester and a composition according to a mass ratio of 1: 1.7. The composition comprises, by mass, 30 to 32 parts of a polyester 3628, 40 to 45 parts of a polyether 330, 200 to 300 parts of reinforced glass fibers, 20 to 30 parts of a polyester 2056, 25 to 35 parts of a polyester 6300, 1.5 to 2 parts of silicone oil, 8 to 10 parts of diethanolamine, 1.5 to 1.7 parts of a catalyst HP-42, 1 to 1.3 parts of a catalyst HP-50, 2.5 to 3.9 parts of water and 33 to 37 parts of a flame retardant DMMP. The silicone oil is silicone oil AK-8005. The preparation method comprises adding the above components into a reactor, carrying out mixing at a stirring rate of 130 to 150 r / min for 4-5h for a reaction to obtain the composition, and uniformly mixing the acetonitrile polyester and the composition according to a mass ratio of 1: 1.7 to obtain the foaming material. The eco-friendly flame-retardant polyurethane foaming material for a cab deflector cover has flame retardancy, high temperature resistance, high strength and environmental friendliness.
