Abstract

The invention provides cationic waterborne polyurethane resin for a coating, a preparation method thereof and application in the coating. The cationic waterborne polyurethane resin for the coating isprepared by reacting a plurality of raw material components, the cationic waterborne polyurethane with a molecular main chain containing a structure shown in a formula I is obtained, and a plurality of raw material components comprise, by mass, 70-100 parts of polyhydric alcohols, 50-90 parts of polyisocyanate, 10-30 parts of a first chain extender, 3-18 parts of a second chain extender, 8-20 parts of a compound containing a structure shown in a formula I and 1-12 parts of a salt forming agent. When the cationic waterborne polyurethane resin is used for coating, the cationic waterborne polyurethane resin is safe, non-toxic and high in adhesive force and has a good mosquito repelling effect.

Description

technical field [0001] The invention relates to the field of high molecular polymers, and specifically discloses a cationic water-based polyurethane, a preparation method thereof and an application in water-based paints. Background technique [0002] Coatings containing cationic waterborne polyurethane resins are widely used in furniture decoration and building walls due to their safety, non-toxicity, high adhesion, and water-based environmental protection. At present, pests such as mosquitoes have brought a lot of troubles to human life. After being bitten, not only will the human body experience itching symptoms, but the greater harm is that when sucking blood, viruses such as malaria parasites, filarids, and Japanese encephalitis can be injected into the human body. cause human infection. Therefore, mosquitoes not only bite people and suck blood to affect sleep, but also spread Japanese encephalitis, malaria, dengue fever, blood filariasis, etc., which have brought great...
