摘要： The invention relates to a method for producing a polyurethane foam, wherein a mixture having the following is discharged from a mixing head through a discharge line: A) a component reactive toward isocyanates; B) a surfactant component; C) a blowing agent component selected from the group comprising linear, branched, or cyclic C1 to C6 hydrocarbons, linear, branched, or cyclic C1 to C6 fluorocarbons, N2, O2, argon, and/or CO2, wherein the blowing agent C) is present in the supercritical or near-critical state; and D) a polyisocyanate component. The component A) has a hydroxyl value=100 mg KOH/g and =1000 mg KOH/g. The blowing agent component C) is present at least partially in the form of an emulsion, and means provided with an opening or several openings are arranged in the discharge line in order to increase the flow resistance during the discharge of the mixture comprising A), B), C), and D), wherein the cross-sectional area of the opening or the sum of the cross-sectional areas of all openings is =0.1% and =99.9% of the inner cross-sectional area of the discharge line.

摘要： The present invention relates to a process for producing a rigid polyurethane-polyisocyanurate foam C, comprising the step of reacting (i) an isocyanate-terminated prepolymer B with (ii) an activator component A comprising at least one trimerisation catalyst A1 and at least one blowing agent A3 in a reaction mixture to form a foam, characterised in that—there is used an isocyanate-terminated prepolymer B obtained from a reaction of an isocyanate B1 having a mean isocyanate functionality of from ≧2.3 to ≦2.9 with a polyol component B2, and—the activator component A comprises water as the blowing agent A3 in an amount of from ≧5 wt. % to ≦50 wt. %,—the isocyanate index in the reaction mixture is in a range of from ≧400 to ≦500, and—the isocyanate content of the prepolymer B is in a range of from ≧21 wt. % to ≦30 wt. %, based on the total mass of the prepolymer B, and—wherein in the reaction of the prepolymer B and the activator component A a conversion contribution to polyisocyanurate of ≦75% is achieved. Rigid foams C so produced have good flame retarding properties while at the same time having good insulating properties and stability properties. The present invention relates further to a rigid polyisocyanurate foam C produced by the process according to the invention, to the use of such a rigid polyisocyanurate foam C in the production of heat-insulating structural components, and to a heat-insulating structural component comprising such a rigid polyurethane-polyisocyanurate foam.
