Description
Technical Field
The invention relates to the technical field of coatings, in particular to skin-touch interior wall finish emulsion paint with high washing resistance and stain resistance and a preparation method thereof.
Background
The skin-feel paint is a paint which is as fine, smooth and elastic as the skin of a baby, can bring very comfortable experience to a user, and is widely applied to water-based furniture paint. As a water-based furniture paint product, the main performance requirements are hardness, adhesive force, wear resistance, scratch resistance and the like. In order to meet the requirements of the performance indexes, most of the formula of the water-based furniture paint is two components, wherein the component A contains water-based hydroxy acrylic emulsion, the component B is isocyanate curing agent, and hydroxyl in hydroxypropyl emulsion of the component A and isocyanate in the curing agent of the component B generate covalent crosslinking through chemical reaction to form a firm network structure during film forming.
With the pursuit of higher quality of home life of people, the demand of the emulsion paint for the inner wall finishing with skin-feeling effect is generated, however, the related products of the emulsion paint for the skin-feeling inner wall finishing and the preparation technology thereof are not disclosed at present. Different from skin-feel paint, on one hand, the performance requirements of the interior wall finish emulsion paint mainly lie in scrub resistance, stain resistance, light transmittance and the like, and are different from the performance of the product conventionally required by the skin-feel 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 interior wall finishing emulsion paint is interior wall putty, and the flatness and the expansion stability of the interior wall finishing emulsion paint are far inferior to those of furniture wood.
For example, chinese invention patent CN114350197A discloses an antibacterial skin-feel paint and a preparation method thereof, the paint is prepared by adopting an emulsion of two combinations of an aqueous polyurethane dispersion and a hydroxyl acrylic emulsion as a component A and a sulfonate and polyether modified aqueous curing agent as a component B, and can realize that a paint film is safe, non-toxic, has a quick sterilization function and has soft and non-sticky skin-feel; chinese invention patent CN113999601A also discloses a two-component aqueous full-matte high scratch-resistant skin-feel finish, which is prepared by taking three combined emulsions of hydroxyl acrylic emulsion, skin-feel resin and aqueous polyurethane dispersion as component A and aqueous curing agent as component B, has high scratch resistance, water resistance and chemical resistance, and simultaneously can ensure skin-feel effect and paint film hardness. There is no mention of the problems of scrub resistance, stain resistance and stretch resistance required for skin feel paints when applied to interior wall finish emulsion paints. Therefore, it is necessary to develop a new skin-feel paint formulation to meet the higher product performance requirements and construction conditions required for interior wall finish emulsion paints.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the invention provides a skin-feel interior wall finish emulsion paint with high washing resistance and stain resistance and a preparation method thereof, so as to achieve the stretching resistance, the high washing resistance and the high stain resistance required by the interior wall finish emulsion paint.
In order to solve the technical problems, the invention adopts the technical scheme that:
the invention provides a skin-touch inner wall finish emulsion paint with high washing resistance and stain resistance, which comprises a component A and a component B, wherein the component A comprises the following components in parts by weight:
60-90 parts of anionic aliphatic polyester polyurethane dispersoid, 0.1-0.5 part of pH regulator, 0.2-5 parts of film-forming additive, 0.2-5 parts of antifreeze, 0.2-0.5 part of preservative, 0.2-1 part of defoamer, 0.1-1 part of polyurethane thickener and water which are complemented to 100 parts;
the anionic aliphatic polyester polyurethane dispersion contains carboxyl, carbamate and carbamido;
the component B is a water-based isocyanate curing agent.
The invention provides a high-scrubbing-resistance and stain-resistance skin-feel interior wall finish paint, which is different from the conventional skin-feel paint in that the conventional skin-feel paint is applied to water-based furniture paint by using a formula that hydroxyl contained in hydroxypropyl emulsion in a component A and isocyanate in isocyanate curing agent in a component B are subjected to chemical reaction to generate covalent crosslinking to form a network structure so as to form a film, but the component A is selected from an anionic aliphatic polyester polyurethane dispersoid, groups in the structure are carboxyl, carbamate and carbamido, and the carboxyl, carbamate and carbamido do not have the activity of chemical reaction with the water-based isocyanate curing agent in the component B at normal temperature, the isocyanate reacts with water on the surface of anionic aliphatic polyester polyurethane dispersoid particles to form crosslinked polyurea, and then the polyurea molecular chain and the molecular chain in the anionic aliphatic polyester polyurethane dispersoid are intertwined to form a physically crosslinked interpenetrating polymer network structure so as to form the film. The method for forming the film has the advantages that the original outstanding performance of the anionic aliphatic polyester polyurethane dispersoid can be well maintained after the anionic aliphatic polyester polyurethane dispersoid is cured to form the film, the problem of paint film cracking caused by the expansion of putty in the process of applying the aliphatic polyester polyurethane dispersoid with specific performance to the base material of interior wall putty can be avoided by selecting the aliphatic polyester polyurethane dispersoid with specific performance, the excellent skin feel effect is shown, and the scrub resistance and stain resistance of the cured paint film are greatly improved, so that the product requirement of the interior wall finish surface emulsion paint is met.

| Comparative example 3 | Has cracks | 3 | <1000 times (one-time) | 30 |
As can be seen from the above Table 1, the skin-feel interior wall finishing emulsion paints of examples 1 to 3 of the present invention had a flat and smooth paint film, excellent skin feel, high scrub resistance and high stain resistance, as compared with the skin-feel interior wall finishing emulsion paints of comparative examples 1 to 3, in which the paint film cracked, the skin feel was poor, the number of times of scrub resistance was low and the stain resistance was poor. Therefore, the skin-feel interior wall finishing emulsion paint can still form a perfect paint film and show excellent skin-feel effect when being applied to rough and uneven interior wall putty, and has the performances of high washing resistance, high stain resistance and the like required by interior wall finishing emulsion paint. Meanwhile, as can be seen from the comparison of example 1 with comparative examples 1 to 3, the chemical bonding of the hydroxyl group contained in component a and the isocyanate in component B at normal temperature affects the appearance, skin feel, scrub resistance and stain resistance of the system after curing to form a film.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
