FIELD: textile industry.SUBSTANCE: disclosed is a water-base resin binder for use in inorganic fibre material, where the resin binder is obtained by reacting at least the following components in any order: (a) protein-like material which is a protein hydrolysate which is considerably soluble in water at 20°C and has viscosity of less than 50 mPa?s for 25 wt % aqueous solution, (b) an aromatic hydroxyl compound and (c) aldehyde, and where the water-base resin binder has viscosity of less than 100 mPa?s when measured in concentration of 50 wt % at 20°C.EFFECT: during solidification, the obtained resin has lower release of phenols and the release of formaldehyde and ammonia is considerably lower compared to traditional resins.15 cl, 8 ex, 13 tbl |
