Combining a polyisocyanate, a polyether polyol, and a trimerization catalyst with a bound material to form a reactive composite; and reacting the reactive composite at an elevated temperature in the next step; Here, the amount of the reactive binder composition is 1 to 60% by weight based on the total amount of the amount of the reactive binder composition and the amount of the bound substance, and the amount of the bound substance is 40 to 99% by weight. %, The total amount of polyisocyanate and polyol is such that the index of the reactive binder composition is 150-10000, and the polyol has an average equivalent weight of 100-2500 and an oxyethylene content of at least 50% by weight. A method for producing a polyisocyanurate composite, which is a polyol having In addition to the polyisocyanurate composite obtained from this process, a reactive composite is also claimed. |
