Document Type and Number:
WIPO Patent Application WO/2019/050439
Kind Code:
A3
Abstract:
A heat- and sound-insulating material containing mineral fibers 0.5 to 10.0 microns in diameter and a binder obtained by curing an aqueous composition containing polyvinyl alcohol, modified starch and processing additives, as well as a combination of two dehydrating agents, wherein the primary dehydrating agent is at least one substance selected from among an organic titanium compound, an organic nickel compound, and a boron-phosphorus compound, and the additional dehydrating agent is at least one substance selected from among silver salts, rhenium salts, zirconium salts and cerium salts. The invention also relates to a method for producing such material. The invention makes it possible to substantially increase the ease and environmental safety of the process of manufacturing articles from fibrous material based on a non-phenol formaldehyde binder, and to improve the characteristics of the finished product.
