Abstract
A silicate modified polymer foam material for filling and sealing contains prepolymerized isocyanate and a silicate modified aqueous solution with a mass ratio in a range of 1:(1.2-1.4). In the prepolymerized isocyanate, a mass percentage of P is 4.4%, a mass percentage of N is 7.9%, and a mass percentage of —NCO is 11.9%. The silicate modified aqueous solution includes liquid sodium silicate, small molecule alcohol, water and a catalyst, wherein the liquid sodium silicate, the small molecule alcohol, the water and the catalyst account for 63-66%, 17-20%, 14-17% and 1.5-2.5% of the weight of the silicate modified aqueous solution respectively. A method of preparing the silicate modified polymer foam material for filling and sealing includes mixing the prepolymerized isocyanate with the silicate modified aqueous solution.
