Abstract

The invention discloses a two-component elastic coating and a preparation method thereof. The two-component elastic coating comprises a component A and a component B, wherein the component A comprises60-70 parts of a waterborne polyurethane dispersion, 1.5-2.5 parts of a lignocellulose / expandable graphite composite material, 1-8 parts of a feel aid, 8-10 parts of organic silicon ketone powder, 0.05-0.5 part of nano-silver, 0.5-1 part of negative ion powder, 3-6 parts of a flame retardant, 0.2-1 part of fumed silica, 0.3-0.5 part of a pH adjuster, 1-3 parts of a base material wetting agent, 5-10 parts of a pigment, 2-3 parts of a defoaming agent, 5-10 parts of a dispersant, 3-7 parts of a film-forming aid, 0.2-0.8 part of a thickener, and 20-30 parts of water; and the component B comprises20-25 parts of a waterborne isocyanate curing agent, and 10-15 parts of a co-solvent. The provided two-component elastic coating has multiple advantages such as high elasticity, good stain resistance, and good scratch resistance, and has relatively high practical value.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a two-component elastic coating and a preparation method thereof. Background technique [0002] Elastic paint is based on synthetic resin emulsion, formulated with pigments, fillers and additives. After applying a certain thickness (dry film thickness greater than or equal to 150μm), it has the elasticity of covering the fine cracks caused by the expansion and contraction of the base material. functional coatings. Elastic coatings have the characteristics of rich expressiveness, strong three-dimensional effect, strong plasticity, strong adhesion, scrub resistance, no fading, no cracking, good scratch resistance, and strong automatic repairing ability, and are favored by more and more people. The market share is expanding rapidly. [0003] In recent years, with the improvement of people's living standards, people's requirements for the comfort of automobile interiors have also ...
