Document Type and Number:
WIPO Patent Application WO/2024/031542
Kind Code:
A1
Abstract:
The present application provides a modified bio-based waterborne polyurethane, a method for preparing same, and use thereof. The modified bio-based waterborne polyurethane is prepared from the following starting materials: 50-150 parts by weight of a bio-based polyol, 5-30 parts by weight of a diisocyanate, 0.1-10 parts by weight of a reactive emulsifier, 20-200 parts by weight of an alkenyl-containing monomer, and 0.01-5 parts by weight of an initiator, wherein the diisocyanate includes aliphatic diisocyanates containing an odd number of carbon atoms. According to the present application, by means of the design and compounding of the starting materials, the modified bio-based waterborne polyurethane is made to have an adjustable thermal activation temperature, high film-forming strength, good weather resistance, complete resistance to yellowing, good adhesion to different substrates, excellent bonding performance, heat resistance, water resistance, hydrolysis resistance, stability, and high bio-base content. The modified bio-based waterborne polyurethane is prepared using a solvent-free method and is an environmentally friendly high-performance waterborne polyurethane product.
