Abstract

The invention relates to a water-based elastic paint with high drying speed and long activating period and a preparation method thereof. The elastic paint is prepared from a component A resin paint and a component B curing agent at mass ratio of 2:1, wherein the component A resin paint comprises 10-30 parts of waterborne polyurethane dispersoid, 30-50 parts of waterborne acrylic emulsion, 1-5 parts of anti-settling agent, 0.2-0.5 part of de-foaming agent, 0.2-1.0 part of wetting flatting agent, 0.2-0.6 part of water-based drier, 0.2-0.5 part of pH regulator additive, 5-10 parts of extinction powder and 10-30 parts of a solvent A and the component B curing agent comprises 55-70 parts of a curing agent and 15-35 parts of a solvent B. Compared with the prior art, the paint has the advantagesthat the preparation method is simple, the raw material source is wide and the prepared elastic varnish surface has excellent touch feel, high drying speed, long activating period, high transparency,high interlayer adhesion, high hardness and excellent anti-scratching property.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based elastic paint with quick drying and long pot life and a preparation method thereof. Background technique [0002] With the development of social industry and the improvement of people's awareness of environmental protection, people have put forward higher requirements for the appearance and decoration effect of daily necessities, especially the parts that are often touched by hands need a more comfortable feel, and elastic paint should be born for this. Elastic paint has excellent ductility, recovery and flexibility, and can well adapt to changes in thermal expansion and contraction of plastics and other materials, improving the elastic feel of the substrate and excellent visual effects. However, traditional elastic paints use a large amount of solvents, causing VOC emissions to pollute the environment. For example, patent CN102229782 discloses a kind of PU elasti...
