Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem that the fragrance in the existing fragrance paint has a large volatilization loss during the paint storage process, which leads to insufficient fragrance persistence after use and cannot continuously improve the indoor air, and provides a two-component water-based Polyurethane coatings, add fragrance slow-release particles that can be stored stably in the paint, and control the release of fragrance loaded in the fragrance slow-release particles through the mixed use of two components, effectively reducing the volatilization loss of fragrance during the storage of the paint, making the paint Long-lasting improvement of indoor air

Abstract

The invention discloses a two-component water-based polyurethane coating with clean smell and fragrance, which comprises component A and component B which are individually packaged and mixed at a mass ratio of 10: (2-3) during use; the raw materials of component A include: 50 ~70 parts of waterborne hydroxyacrylic resin, 10~30 parts of pigment, 2~3 parts of dispersant, 0.2~0.4 part of defoamer, 0.2~0.5 part of leveling agent, 1~3 parts of sodium carbonate; the raw materials of component B include : 70-90 parts of isocyanate curing agent, 15-25 parts of solvent, 30-50 parts of fragrance slow-release particles, fragrance slow-release particles are mesoporous TiO loaded with plant essential oils 2 , Mesoporous TiO 2 The surface is modified with a complex of polyvinylimidazole and Cu(II). The invention adds fragrance slow-release particles to the paint, and controls the release of fragrance loaded in the fragrance slow-release particles through the mixed use of two components, reduces the volatilization loss of fragrance during paint storage, and can permanently improve indoor air.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a two-component water-based polyurethane coating with clean odor and fragrance. Background technique [0002] In recent years, people have paid more and more attention to the impact of indoor air quality on human health, and paid more attention to the health and environmental protection of decoration materials. When choosing paints, environmentally friendly and healthy odor-free products have become the main needs of consumers. The current environment-friendly odor-cleaning paint generally uses water-based paint instead of traditional organic solvent paint to reduce the release of volatile organic compounds, and adds spices to the paint to mask the smell of the paint. [0003] For example, the patent of Publication No. CN111100522A discloses a kind of interior wall paint with lasting fragrance, and the EO group in the polymer latex used in it forms strong hydrogen bond with the...
