摘要： The invention relates to a method for the production of polyisocyanate/polysilicic acid based resins with widely variable processability period and setting period by reacting one or more polyisocyanates with water glass optionally in the presence of one or more additives and/or auxiliary agents conventionally used in the production of polyisocyanate/polysilicic acid based resins. According to the invention the reaction is performed in the presence of one or more cocatalysts comprising mobile hydrogen of acidic character, wherein the cocatalyst is a compound comprising a structural unit of formula (I) a metal chelate thereof or a derivative thereof in which one of the mobile hydrogens of acidic character is replaced by a substituent X, wherein X represents halo, hydrocarbyl, hydrocarbyl-oxy, hydrocarbyl-carbonyl, hydrocarbyl-oxy-carbonyl or hydrocarbyl-carbonyl-amido group or a combined group formed from two or more of these groups, and the cocatalyst is used in an amount of at least 0.01% by weight calculated for the combined weight of polyisocyate(s) and water glass.

摘要： Polyisocyanate based elastomers and foams, having adjustable gelling periods are pred. from an MDI prepolymer system. The system comprises 1:(2-5) pts.wt. mixt. of components 'A' and 'B'. Component 'A' contains (all wt.%-s): 30-70 H2O 30-60 alkali-earth-oxide, -oxide-hydroxide, hydroxide or their mixts. 0-20 calcium and/or magnesium salts of organic acids, having high water solubility. 0-10 aq. soluble nonionic surfactant 0-30 customary additives. 1 pt.wt. of component 'A' is added to 2-5 pts.wt. of component 'B'. Component 'B' contains (all wt.%-s): 30-100 MDI prepolymer, i.e. a mixt. that contains di:phenyl-methane-di:isocyanate, of which at least 51 wt.% is 4,4' MDI. the remainder may be a different MDI isomer and/or a modified MDI and/or TDI. The prepolymer is prepd. by a reaction of the isocyanate with poly-propylene-glycol, and/or poly-(ethylene-propylene) glycol, inn such a manner that the poly-ether-alcohol chain's avg. mol.wt. should be 800-8000/mole; the number ratio of ethylene oxide:propylene oxid should be (0-1):1 units and that the average free NCO content of the prepolymer should be 1.5-15 wt.% when calculated on the complete wt. of the prepolymer. The prepolymer also contains: 0-50 MDI, polymeric MDI, modified MDI or a mixt. of these; 0-40 plasticising and/or thinning additive; 0-10 auxiliary blowing agent; 0-30 customary components compatible additions. Pts. 'A' and 'B' are mixed and allowed to gel. Prods. based on these schemes are also protected.
