REACTION SYSTEM FOR PRODUCING PUR AND PIR HARD FOAM MATERIALS CONTAINING LAYER SILICATES |
摘要 |
The invention relates to a reaction system for producing PUR and PIR hard foam materials, comprising the following components: A) a compound which is reactive towards isocyanates; B1) a surfactant component; C) a propellant in a supercritical or near-critical state; D) a polyisocyanate; and E) a layer silicate. The invention further relates to a reaction system for producing PUR and PIR hard foam materials, comprising the following components: B2) a surfactant component with functional groups which are reactive towards isocyanates; C) a propellant in a supercritical or near-critical state; D) a polyisocyanate; and E) a layer silicate. The invention further relates to a method for producing PUR and PIR hard foam materials and to PUR and PIR hard foam materials which can be obtained from the aforementioned reaction systems. |
