Abstract: A process for preparing solvent-free aqueous polyurethane dispersion modified with acrylic grafting is divided into four steps. The first step is a reaction of a diisocyanate with a polyol to prepare a prepolymer; the second step involves diluting the prepolymer with an acrylate monomer and adding a sulfonate-based chain extender to react; the third step involves adding deionized water and a water-soluble diamine-based chain extender to obtain a solvent-free sulfonate-based aqueous polyurethane dispersion; and the fourth step involves letting the aqueous polyurethane become modified with acrylic grafting. The resulting aqueous polyurethane has excellent mechanical strength, heat resistance and water resistance.

Abstract: Provided is a PET chemical recycling method. The PET chemical recycling method includes the following: adding a PET chemical recycling ion catalyst material for PET chemical recycling to PET waste and ethylene glycol; heating and stirring to obtain depolymerized and decolorized bis(2-hydroxyethyl)terephthalate (BHET); and filtering and recycling the ion catalyst material for PET chemical recycling. The PET chemical recycling ion catalyst material is a bisalkylimidazole-metal tetrachloride ionic liquid grafted on a porous carrier.
