摘要： Isocyanate prepolymers which are useful as binders are made from a polyisocyanate mixture and a hydroxyl compound having at least about 1 hydroxyl group. The polyisocyanate mixture is made up of from about 50 to about 60% by weight of polyphenyl polymethylene polyisocyanate and from about 40 to about 50% by weight of an isomeric mixture of diphenylmethane diisocyanate (MDI). The isomeric mixture of MDI is made up of from about 4 to about 30% by weight of the 2,4'-isomer and from about 70 to about 96% by weight of the 4,4'-isomer. The binders of the present invention are advantageous in that they may be used in high moisture, low temperature conditions without a catalyst. Reduced MDI emissions are also achieved when the binders of the present invention are used to make composite materials.
