METHOD OF PRODUCING POLYISOCYANURATE COMPOSITE MATERIAL Russian patent published in 2011 - IPC C08G18/10 C08G18/48 C08G18/16 C08G18/72 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing polyisocyanurate composite material, involving merging polyisocyanate, monoatomic alcohol polyester and a trimerisation catalyst, - these three components, merged together, are called a "reactive binding composition", - with binding material to form a reactive composite material, which allows, during the next step, high-temperature reaction of said reactive composite material, in which the amount of the reactive binding composition is equal to 1-60 wt % and the amount of the binding material is equal to 40-99 wt %, both in terms of the amount of the reactive binding composition plus the amount of the binding material, and in which the amount of polyisocyanate and monoatomic alcohol is such that the reactive binding composition index is equal to 150-10000, wherein the monoatoic alcohol polyester has average equivalent weight of 10-2500 and content of oxyethylene is at least 65 wt %. The invention also describes said reactive composite material and composite materials obtained using said method and from disclosed reactive composite materials.

EFFECT: obtaining polyisocyanurate composite material, having good thermal stability, fire-resistant properties and very low level of remaining free NCO groups.
