RESIN AS BINDING AGENT FOR MINERAL FIBER, BINDING AGENT, METHOD FOR PREPARING RESIN, APPLYING RESIN AND PRODUCT BASED ON MINERAL FIBER Russian patent published in 2005 - IPC

FIELD: building materials.

SUBSTANCE: invention relates to preparing binding agents for mineral fibers. Invention describes preparing resin used as a binding agent suitable for mineral fibers, such as glass-wool or stone wool containing product of interaction of amine with the first anhydride and the second anhydride. The first and second anhydrides represent different cyclic anhydrides wherein the first cyclic anhydride represents aliphatic anhydride and the second cyclic anhydride represents aromatic anhydride. Also, invention claims a binding agent based on above said resin and product hardened with this binding agent. Invention provides preparing a binding agent for mineral fibers satisfying to more high ecological requirements.

EFFECT: improved method for preparing resin, valuable properties of resin.
