Title:
MODIFIED ROSIN RESIN, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/120036
Kind Code:
A1
Abstract:
The present invention provides a modified rosin resin, a preparation method therefor, and an application thereof. The modified rosin resin is prepared by the reaction of rosin, a benzene ring-containing carboxylic acid, an epoxy compound, maleic acid and a derivative thereof, and a hydroxyl group-containing ether compound. The modified rosin resin provided by the present invention introduces a hydrophobic benzene ring into the rosin molecule and reacts the hydroxyl group-containing ether compound with a hydrophilic carboxyl group, to form a hydrophilic group having low hydrophilicity, thereby greatly improving the water resistance of the rosin resin, and does not use an organic solvent as a reaction medium in the preparation process of the modified rosin resin, thereby avoiding environmental pollution and solvent residue in the product, achieving safety of use and environmental protection.
