Description
Technical Field

Background
Skin-feel paint is paint with the touch feeling as fine, smooth and elastic as the skin of infants, can bring very comfortable experience to users, and is widely applied to water-based furniture paint. As water-based furniture paint products, hardness, adhesion, abrasion resistance, scratch resistance, and the like are required as main properties. In order to meet the requirements of the performance indexes, the water-based furniture paint is mainly composed of two components, wherein the component A contains water-based hydroxyl acrylic emulsion, the component B is isocyanate curing agent, and the hydroxyl in the component A hydroxyl acrylic emulsion and the isocyanate in the component B curing agent generate covalent crosslinking through chemical reaction to form a firm network structure during film formation.
With the pursuit of higher and higher household life quality, the demand for the interior wall finish emulsion paint with the skin feel effect is generated, but related products of the skin feel interior wall finish emulsion paint and the preparation technology thereof are not disclosed at present. On the one hand, the performance requirements of the inner wall finish emulsion paint are mainly that the paint has scouring resistance, stain resistance, light transmittance and the like, and the performance requirements of the inner wall finish emulsion paint are different from the product performance required by the conventional skin paint; on the other hand, the main construction base material of the skin-feel paint is a flat and structurally stable wood surface, while the construction base material of the inner wall finish emulsion paint is inner wall putty, and the flatness and the expansion stability of the inner wall putty are far inferior to those of furniture wood.
For example, chinese patent No. 114350197A discloses an antibacterial skin-feel paint and a preparation method thereof, wherein the antibacterial skin-feel paint is prepared by adopting an emulsion of two combinations of aqueous polyurethane dispersoid and hydroxy acrylic emulsion as a component A and a sulfonate and polyether modified aqueous curing agent as a component B, so that the paint film is safe and nontoxic, has a rapid sterilization function, and has soft and non-sticky skin-feel; chinese patent No. 113999601A also discloses a double-component water-based full-matt high scratch-resistant skin-feel finishing paint, which is prepared by taking three combined emulsions of hydroxyl acrylic emulsion, skin-feel resin and water-based polyurethane dispersoid as a component A and taking a water-based curing agent as a component B, and has high scratch resistance, water resistance and chemical resistance, and meanwhile, the skin-feel effect and the hardness of a paint film can be ensured. However, there is no mention of the problems of wash resistance, stain resistance and stretch resistance required for skin feel paints if applied to interior wall finish emulsion paints. It is therefore highly desirable to develop a new skin feel paint formulation to address the higher product performance requirements and construction conditions required for interior wall finish emulsion paints.

As is clear from Table 1 above, the skin-feel interior wall finish latex paints of examples 1 to 3 of the present invention possess a flat and smooth paint film, excellent skin feel, high wash resistance and high stain resistance, as compared with the skin-feel interior wall finish latex paints of comparative examples 1 to 3, which exhibit paint film cracking, poor skin feel, low wash times and poor stain resistance. Therefore, the skin-feel interior wall finish emulsion paint can still form a perfect paint film and has excellent skin-feel effect when being applied to rough interior wall putty, and has the performances of high washing resistance, high stain resistance and the like required by the interior wall finish emulsion paint. Meanwhile, it is understood from example 1 that the chemical bonding of the hydroxyl group contained in the component A with the isocyanate in the component B at normal temperature affects the appearance, skin feel, washing resistance and stain resistance of the system after it is cured into a film, as compared with comparative examples 1 to 3.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
