▎ 摘　　要

NOVELTY - Solvent-free synthetic material comprises 45-75 pts. wt. isocyanate prepolymer, 25-35 pts. wt. hydroxyl alkyd resin, 5-15 pts. wt. low temperature resistant polyester polyol, 5-10 pts. wt. trifluoroethanol, 5-10 pts. wt. hexafluoro butyl alcohol, 10-20 pts. wt. secondary amino compound, 40-80 pts. wt. weather resin, 5-10 pts. wt. modified powder, 1-6 pts. wt. pigment, 1-4 pts. wt. ultraviolet absorbent, 1-3 pts. wt. antifoaming agent, and 0.02-0.1 pts. wt. catalyst. The modified powder is amino silanization modified silicon nitride-graphene nano powder material. USE - Solvent-free synthetic material for ice and snow motion. ADVANTAGE - The solvent-free synthetic material has excellent mechanical property and low-temperature resistance, with wide application prospect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing solvent-free synthetic material, which involves adding the isocyanate prepolymer into the reaction kettle under the protection of nitrogen, adding hydroxyl alkyd resin, low temperature resistant polyester polyol, trifluoroethanol and hexafluorobutanol, raising the temperature to 85-95degrees Celsius and keeping the temperature and reacting for 1-3h to obtain the A component, mixing the pigment and the secondary amino compound, grinding until the fineness is less than 50~mm, adding the A component, modified powder, weather-resistant resin, antifoaming agent, ultraviolet absorbent and catalyst, and reacting for 60-50 hours under the 60-80 degrees Celsius to obtain the solvent-free synthetic material.
