RESIN FOR PRODUCING AN INORGANIC FIBER MATERIAL

摘要

A water dilutable binder resin for use in an inorganic fiber material; wherein the binder resin is prepared by reacting at least the following components in any order: (a) proteinaceous material which is substantially soluble in water at 20oC and has a viscosity of < 50 mPa*s for a 25wt% aqueous solution, (b) an aromatic hydroxyl compound, and (c) an aldehyde, and wherein the water dilutable binder resin has a property of having a viscosity of <100 mPa*s when measured at a concentration of 50wt% at 20oC. During curing, the resin thus produced gives lower phenol emissions. Also, the formaldehyde and ammonia emissions are dramatically lower when compared to conventional resins.
