WIPO Patent Application WO/2023/184755
Kind Code:
A1
Abstract:
The present invention provides a special high-water-resistance bio-based formaldehyde-free setting agent for mineral wool, comprising the following components in parts by weight: 100 parts of a water-soluble resin prepolymer; 30-250 parts of a bio-based carbohydrate; 0-100 parts of monomolecular polycarboxylic acid; 0-5 parts of a wet strength modifier; 2-15 parts of a catalyst; and 0-20 parts of a pH value regulator. In the setting agent of the present invention, the natural renewable resource bio-based carbohydrate is used as a raw material, so that the mode of relying on petroleum resource raw materials is changed, the setting agent is a more environmentally-friendly material, and meanwhile, the costs of the setting agent are greatly reduced. In addition, the setting agent prepared by the present invention does not release free formaldehyde, meets the standard requirements of environmental protection, no VOC, and no formaldehyde, and has good dry and wet strength and water resistance, and the comprehensive performance that the dry strength is greater than 4.0 MPa, the wet strength is greater than 3.0 MPa, and the strength retention rate is greater than 60% can be achieved.
