Title:
PREPARATION METHOD FOR ORGANIC TITANIUM PRECURSOR POLYMER TPP-II AND APPLICATION THEREOF IN SPECIAL COATING
Document Type and Number:
WIPO Patent Application WO/2019/210528
Kind Code:
A1
Abstract:
A preparation method for an organic titanium precursor polymer TPP-II and an application thereof in a special coating, relating to the technical field of preparation for and application of new materials. Under the catalysis of gamma-phase nanometer aluminum oxide, a mixture of hydrogenated titanium powder, epoxy resin, a nano-dispersant, a titanate coupling agent, a silane coupling agent, and a solvent is placed in a ball-milling reaction tank for a ball milling reaction under ultrasonic conditions; under the coupling action of mechanical force and ultrasonic waves, not only the micron-sized titanium hydride is refined to the nanometer scale, but also a chain scission, grafting and polymerization of a high-molecular polymer is induced; and an organic titanium precursor polymer TPP-II with a hydroxyl group structure is obtained by ring opening of epoxy groups. The organic titanium precursor polymer TPP-II can be used to prepare an anti-acid corrosion protection material in a high temperature environment, such as primers and finishing coats of a flue gas desulfurization system and a heat exchanger device.
