20130123378 | PROCESS FOR PRODUCING RIGID FOAMED SYNTHETIC RESIN - A process for producing a rigid foamed synthetic resin, which comprises reacting a polyol mixture (P) containing a polyol (A) and a polyol (B) and a polyisocyanate compound (I) in the presence of a blowing agent containing water, a catalyst, a foam stabilizer and a flame retardant. The polyol (A) is a polyether polyol having a hydroxyl value of from 56 to 250 mgKOH/g, obtainable by subjecting an alkylene oxide to ring-opening addition polymerization to a bisphenol compound. The polyol (B) is a polyether polyol having a hydroxyl value of from 100 to 800 mgKOH/g, obtainable by subjecting an alkylene oxide to ring-opening addition polymerization to a Mannich condensation product. | 05-16-2013 |
20130150471 | CATALYZED EPOXY-CARBOXYLIC ACID SPRAY FOAMS AND METHODS OF USING SAME - A foamable composition, foamed product and method of forming a foamed product are disclosed. The foamed product includes an epoxy resin crosslinked with a polycarboxylic acid to form a polymeric foam having cells filled with a blowing agent. The reaction between the epoxy resin and the carboxylic acid is catalyzed by a chromium (III) catalyst, particularly an active, carboxylated chromium salt, so as to speed the reaction at ambient temperature to allow the foam to set and cure so rapidly that, when applied to a vertical surface, the effects of gravity do not destroy the foam by pulling it down before the foam sets. Other ingredients preferably include a rheology modifier or thixotrope. The foams may be used for a wide variety of applications including sealing and/or insulating building structures. | 06-13-2013 |
20130274358 | METHOD FOR PRODUCING POLYETHER POLYOL AND METHOD FOR PRODUCING RIGID FOAM SYNTHETIC RESIN - To provide a method for producing a polyether polyol having a low viscosity and little odor, whereby when a rigid foam synthetic resin is produced, good strength and flame retardancy can be obtained. A method for producing a polyether polyol, which comprises ring-opening addition of an alkylene oxide to an initiator obtainable by reacting a phenol, an aldehyde and an alkanolamine, and which comprises a first step of ring-opening addition of at least one member selected from propylene oxide and butylene oxide to the initiator in the absence of a catalyst, and a second step of ring-opening addition of an alkylene oxide of which at least a part is ethylene oxide, to a reaction product of the first step, in the presence of a catalyst, wherein the proportion of ethylene oxide in the total amount of the alkylene oxide to be added to the initiator, is from 5 to 95 mol %. | 10-17-2013 |
