Stabilized aqueous phenolic binder for mineral wool and production of mineral wool products

摘要

A stabilized aqueous phenolic binder for mineral wool comprising an emulsified phenolic resin consisting essentially of a phenolic resin having a degree of conversion of phenol of 99 % or more, said binder containing a protective colloidal agent in a concentration of less than 0.1 % by weight based on the solid content of the binder. A method of producing an emulsifiable phenolic resin; an emulsifiable phenolic resin obtainable by the method; a method of producing a stabilized phenolic binder for mineral wool; a stabilized phenolic binder obtainable by the method; use of said binder in production of mineral wool products; methods of producing mineral wool products; and mineral wool products obtainable by the methods.
