Abstract

The invention relates to triptycene derivative modified water-based acrylic resin and a preparation method of the triptycene derivative modified water-based acrylic resin. The resin comprises the following components in parts by weight: 2.0 to 6.0 parts of triptycene derivative, 1.0 to 4.0 parts of crosslinking monomer, 0.2 to 0.8 part of benzoyl peroxide, 2.0 to 8.0 parts of trimethylolpropane trimethacrylate, 2.0 to 5.0 parts of acrylic acid, 10.0 to 30.0 parts of acrylate hard monomer, 15.0 to 45.0 parts of acrylate soft monomer, 1.0 to 4.0 parts of vinyl trimethoxy silane, 10.0 to 25.0 parts of cosolvent, 1.5 to 4.5 parts of neutralizer and 50.0 to 120.0 parts of deionized water. The triptycene derivative modified waterborne acrylic resin prepared by the invention has a series of properties such as good artificial aging resistance, acid and alkali resistance, salt fog resistance, corrosion resistance, water resistance, adsorbability, bacteria resistance, sterilization and the like, and a bactericide does not need to be added when the triptycene derivative modified waterborne acrylic resin is made into a coating. The waterborne acrylic resin can be made into single-component and double-component water-based paint.

Description

technical field [0001] The invention relates to a modified water-based acrylic resin, in particular to a tridecene derivative-modified water-based acrylic resin and a preparation method thereof, belonging to the technical field of synthetic water-based resins. Background technique [0002] Over the years, my country's acrylic resin industry has developed rapidly, and product output has continued to expand. The national industrial policy encourages the acrylic resin industry to develop in the direction of high-tech products, and domestic enterprises have gradually increased investment in new investment projects. Investors are paying more and more attention to the acrylic resin industry, which increases the demand for research on the development of the acrylic resin industry. Acrylic resin paint has excellent gloss and color retention as well as good mechanical properties, good chemical stability, strong film-forming ability, heat resistance, chemical resistance and other prop...
