摘要：Molding mass (X) based on polyisocyanate, polyisocyanate-isocyanurate, polyols, and optionally fillers, additives, colors and accelerators; at least one aliphatic isocyanate based on HDI (hexamethylene diisocyanate) of isocyanate (NCO) content, at least one additive, and accelerator. Molding mass (X) based on polyisocyanate, polyisocyanate-isocyanurate, polyols, and optionally fillers, additives, colors and accelerators comprises (wt.%): (A) component of hydroxy content of 10-26% (10-90); (B) at least one aliphatic isocyanate based on HDI (hexamethylene diisocyanate) of isocyanate (NCO) content of 20-25% (0-90); (C) compound of NCO content of 4-36% (0-
90); (D) at least one additive (0-60); and (E) accelerator (0-5). Provided that at least one of
B and
C is present at (a total of) at least 10%. (A) is one or more of branched polyether-polyols based on sucrose (A1) or propoxylated trimethylolpropane (TMP) (A2), or a trifunctional polyether-polyol based on TMP (A3). (C) is one or more of: prepolymer of polyol and crude MDI (methylene di(phenylisocyanate)) (C1) or IPDI (isophorone diisocyanate) (C2); dimerized TDI (toluylene diisocyanate) or HDI (C3); mixed triazine of TDI and HDI (C4); prepolymer of polyol with HDI-biuret (C5), HDI-uretdione (C6) or allophanate-modified HDI trimer (C7); HDI-isocyanato-isocyanurate (C8)
吴惠贞林志玲范伟床戏or dicyclohexylmethane diisocyanate (C9). (D) is at least one of fine silica, zeolite and/or milled alkali silicate or filler (up to 100%), or additives, colors and ultra-violet protectants
(up to 20%). Independent claims are also included for the following: (a) similar mass (X') in which (A) is (A4), i.e. a long-chain polyether-polyol of molecular weight over 3500 based on propylene glycol, propylene oxide and/or ethylene oxide with hydroxy content 0.1-
5wt.%, optionally mixed with (A1)-(A3); and (b) molded objects prepared from (X) and (X').
