Abstract

The invention provides an anionic waterborne polyurethane resin for a coating, a preparation method thereof, and an application of the anionic waterborne polyurethane resin in the coating. A pluralityof raw material components are reacted to obtain the anionic waterborne polyurethane resin with the molecular main chain containing a structure represented by formula I, wherein the plurality of rawmaterial components comprise 100-140 parts of macromolecular polyol, 100-120 parts of isocyanate, 8-12 parts of a small molecular alcohol chain extender, 10-15 parts of a compound containing the structure represented by the formula I, 0.5-2 parts of a catalyst, 15-25 parts of a hydrophilic chain extender, 11-19 parts of a neutralizer, 0.5-3 parts of a coupling agent, 18-25 parts of an amine chainextender and 500-600 parts of deionized emulsified water. The anionic waterborne polyurethane resin provided by the invention has the advantages of safety, no toxicity, high adhesive film hardness, good water resistance and good mosquito repelling effect when being used for the coating.

Description

technical field [0001] The invention relates to the field of high molecular polymers, and specifically discloses an anionic water-based polyurethane, a preparation method thereof and an application in cosmetics. Background technique [0002] Anionic water-based polyurethane coatings are widely used in furniture decoration, such as wood coatings, due to their safety, non-toxicity, high film hardness, good water resistance, 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...
