Abstract
PURPOSE: To obtain a polyisocyanate resin composition comprising a homogeneously dispersed solid additive, by heating a blend of a polyisocyanate stock solution. powder pulverized under freezing with a solid additive to the curing reaction temperature.
CONSTITUTION: A polyisocyanate resin stock solution is cooled, frozen, and pulverized before the curing reaction proceeds. The powder thus obtained is homogeneously mixed with a solid additive, such as a filler, flame-retardant, stabilizer, reinforcing material, and pigment. The mixture is heated to the curing temperature of the stock solution. According to the method, the curing cam proceed in such a state that the frozen powder and the solid additive are mixed. Thus, a polyisocyanate resin composition comprising a homogeneously dispersed solid additive can be obtained.
