Title:
PREPARATION METHOD FOR NANOMETER MATERIAL CAPABLE OF IMPROVING FIRE RESISTANCE OF WATERBORNE POLYURETHANE COATING AND ADHESIVE
Document Type and Number:
WIPO Patent Application WO/2016/095289
Kind Code:
A1
Abstract:
A preparation method for a nanometer material capable of improving fire resistance of a waterborne polyurethane coating and an adhesive comprises: mixing polytetramethylene ether glycol with isophorone diisocyanate, reacting in the presence of a Pd/Fe3O4-CNT catalyst, so as to obtain a polyurethane prepolymer A; adding dimethylolpropionic acid to the prepolymer A to react, adding triethylamine and carrying out neutral reaction, and adding water for emulsification, so as to form polyurethane B; and adding a nanometer material emulsion C to the polyurethane B, shearing and stirring under the condition that pH is 7, so as to obtain the fire-resistant polyurethane coating and adhesive. The polyurethane material is environmentally-friendly and low in price.
