Environment-friendly polyurethane pavement material and preparation method thereof
The invention discloses an environment-friendly polyurethane pavement material and a preparation method thereof in the technical field of polyurethane. The environment-friendly polyurethane pavement material comprises the following components in parts by weight: a component A: 35-45 parts of modified castor oil polyol, 20-30 parts of diphenylmethane diisocyanate, 2-3 parts of 1, 4-butanediol and 1-1.5 parts of dibutyltin dilaurate; the component B comprises the following components in parts by weight: 9-12 parts of a disulfide modifier, 0.8-1.5 parts of an antioxidant 1010, 1-1.8 parts of ferric oxide, 3-5 parts of bentonite and 25-30 parts of Portland cement; the modified castor oil polyol is prepared from the following components in parts by weight: 45 to 65 parts of castor oil, 8 to 12 parts of mercaptoethanol, 50 to 60 parts of ethyl acetate, 10 to 13 parts of glycerol and 0.05 to 0.06 part of sodium hydroxide. According to the present invention, the hydrophobic effect of the material is achieved by replacing the polyether with the mercaptoethanol modified castor oil polyol so as to achieve the technical effect of no foaming in the presence of water, and the prepared disulfide-based modifier is adopted to modify the material so as to improve the mechanical property and the recovery ability of the material.
