Document Type and Number:
WIPO Patent Application WO/2020/129801
Kind Code:
A1
Abstract:
The present invention provides a binder that is for inorganic fibers and that is characterized by containing (A) 100 parts by mass of a polyvinyl alcohol resin having a degree of polymerization of 100-3500, (B) 1-50 parts by mass of colloidal silica having an average particle size of 100 nm or less, and (C) 3 parts by mass or more of an ammonia-modified copolymer containing maleic anhydride. By using the binder for inorganic fibers according to the present invention, an inorganic fiber mat having resiliency comparable to that of phenolic resins can be fabricated, and the amount of volatile organic compounds released from the inorganic fiber mat is very small.
