Floor using functional paint

Abstract

A floor using a functional paint has a functional coating. And the functional coating is formed by curing paint with a slow-release fragrance function. The paint with the slow-release fragrance function comprises a film-forming substance and a plurality of fragrant microcapsules with different particle sizes, wherein the fragrant microcapsules are dispersed in the film-forming substance. Compared with the prior art, the floorboard using the functional paint, provided by the invention, has better dispersion stability, coating binding force and controllable release performance by uniformly dispersing the fragrant microcapsule as a functional component in a formula system in a production stage. By arranging the functional coating and the protective paint layer, a multi-layer coating structure is formed, the wear resistance is further improved, and the protective paint layer made of different materials can be selected to regulate and control the fragrance release rate of the functional paint. By selecting the fragrance microcapsules with specific particle size distribution, a particle size gradient can be formed in the functional coating, and staged release of fragrance is realized.

Description

Technical Field

[0001] This invention relates to the field of flooring technology, and in particular to a flooring using functional paint. Background Technology

[0002] Currently, as people's living standards gradually improve, their requirements for home decoration also increase, especially for flooring. Flooring is a commonly used decorative material, and there are many types available. However, with the diversification of consumer demands and the increasing pursuit of a high-quality life, single-performance flooring is gradually revealing its limitations. Although existing flooring possesses advantages such as high hardness, wear resistance, and resistance to deformation, and can add a natural and warm atmosphere to the interior environment, its lack of sensory experience, particularly the absence of a pleasant fragrance, limits its application potential in certain special occasions. For example, in spas, yoga studios, high-end hotels, or homes, an environment exuding natural fragrance can provide a more relaxing and comfortable experience.

[0003] Currently, there are two main ways to impart a lasting fragrance to objects: one is to add fragrance directly to the coating, but the fragrance lasts for a very short time; the other is to mix pre-made fragrance microcapsules into the coating as an additive. In particular, the latter method of mixing microcapsules as a post-addition component with the finished coating has limitations in the existing technology: (1) Microcapsules have poor compatibility with the coating system and are prone to agglomeration and sedimentation, resulting in uneven distribution in the coating; (2) The microcapsules and the cured paint film are only physically mixed, with weak bonding force, and are easily detached due to friction or cleaning; (3) The release behavior is simple and it is difficult to achieve intelligent and long-lasting fragrance control. Summary of the Invention

[0004] In view of this, the present invention provides a floor using functional paint to solve the above-mentioned technical problems.

[0005] A floor using a functional paint has a functional coating. The functional coating is cured from a slow-release fragrance functional paint. The slow-release fragrance functional paint comprises a film-forming substance and various fragrance microcapsules of different particle sizes dispersed within the film-forming substance.

[0006] Furthermore, the floor also includes a protective lacquer layer coated on the functional coating.

[0007] Furthermore, the thickness of the protective coating is 10 μm to 30 μm.

[0008] Furthermore, the flavor microcapsules comprise at least two types of microcapsules with different average particle sizes.

[0009] Furthermore, the flavor microcapsules include two types of microcapsules with an average particle size of 25 μm to 40 μm and microcapsules with an average particle size of 5 μm to 15 μm.

[0010] Furthermore, based on the total weight of the sustained-release fragrance functional paint, the content of the fragrance microcapsules is 5wt% to 30wt%, and the content of the film-forming substance is 40wt% to 70wt%.

[0011] Furthermore, the film-forming substance includes an aqueous acrylic resin.

[0012] Furthermore, the wall material of the flavored microcapsules is gelatin-gum arabic.

[0013] Compared with existing technologies, the functional paint flooring provided by this invention achieves an integrated fragrance functional paint by uniformly dispersing the fragrance microcapsules as functional components in the formulation system during the production stage. This results in superior dispersion stability, coating adhesion, and controllable release performance. By setting the functional coating and protective paint layer, a multi-layer coating structure is formed by applying a protective paint layer over the functional paint, further improving wear resistance. Different materials can be selected for the protective paint layer to regulate the fragrance release rate of the functional paint. Furthermore, by selecting fragrance microcapsules with a specific particle size distribution, a particle size gradient can be naturally formed within the functional coating or guided by the construction process, achieving staged fragrance release. Integrating the fragrance microcapsules with the base material to form the paint simplifies the construction process, improves the dispersion stability and adhesion strength of the microcapsules in the coating, and can be widely used for surface coating of substrates such as interior decoration, furniture, and handicrafts.

[0014] Figure 1 This is a structural schematic diagram of a floor using functional paint, provided by the present invention. Detailed Implementation

[0015] The following provides a more detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0016] like Figure 1 The diagram shown is a structural schematic of a floor using functional paint provided by the present invention. The floor using functional paint includes a substrate layer 10, a functional coating layer 20 disposed on the substrate layer 10, and a protective paint layer 30 disposed on the functional coating layer 20. It is conceivable that the floor using functional paint also includes other functional modules such as spraying methods, curing times for different layers, etc., which are techniques well known to those skilled in the art and will not be described in detail here.

[0017] The substrate layer 10 is the floor surface that needs to be painted, including but not limited to wood flooring, composite flooring, etc., as the base layer for setting the functional coating 20, to meet the market demand for fragrance products and increase the added value of the product.

[0018] The functional coating 20 is cured from a slow-release fragrance functional paint and can be applied to the substrate layer 10 by conventional methods such as brushing, rolling, or spraying. It has a uniform thickness and forms a fragrance coating after drying.

[0019] The sustained-release fragrance functional paint is a liquid composition comprising a continuous film-forming substance, fragrance microcapsules uniformly dispersed therein as a dispersed phase, and an additive. Specifically, based on the total weight of the sustained-release fragrance functional paint, the content of the fragrance microcapsules is 5 wt% to 30 wt%, and the content of the film-forming substance is 40 wt% to 70 wt%.

[0020] The film-forming substance is a key component in the coating that forms a continuous film. Its function is to bind other components and determine the basic properties of the coating. For example, water-based acrylic resin and other materials are used as film-forming substances.

[0021] The fragrance microcapsules are prepared using microencapsulation technology. The wall material can be gelatin-gum arabic. By encapsulating the fragrance within the polymer wall material, a stable protective coating is formed. The microcapsule design ensures that the fragrance is not released prematurely under normal conditions, but only under specific conditions. The fragrance microcapsules utilize a variety of microcapsules with different average particle sizes.

[0022] The excipients are the excipients and additives used in the production of products and the formulation of prescriptions. They are the general term for all materials other than the main active ingredient and are important components of the preparation. For example, wetting and dispersing agents and deionized water are used as excipients.

[0023] In one embodiment of this application, the method for preparing the slow-release fragrance functional paint includes the following steps: STEP001: Provide the raw materials for preparation, which are composed of fragrance microcapsules, aqueous acrylic emulsion, wetting and dispersing agent and deionized water, in 100 parts, the fragrance microcapsules are 16 parts, the aqueous acrylic emulsion is 50 parts, the wetting and dispersing agent is 2 parts and the deionized water is 32 parts. STEP002: The fragrance microcapsules, aqueous acrylic emulsion, wetting and dispersing agent and deionized water are stirred evenly and dispersed at high speed to obtain functional paint.

[0024] In step STEP001, the fragrance microcapsules can be jasmine-scented, and at least two types of fragrance microcapsules with different average particle sizes are selected. For example, in this embodiment, 8 parts of large-particle-size capsules with a particle size of 25μm-40μm and 8 parts of small-particle-size capsules with a particle size of 5μm-15μm are selected and mixed in the aqueous acrylic emulsion, wetting and dispersing agent and deionized water.

[0025] In step STEP002, the functional paint is prepared using conventional paint production equipment, such as a high-speed disperser and a sand mill. During the dispersion stage, the fragrance microcapsules are added together with the film-forming substance and the dispersant. During preparation, it is necessary to ensure that the shear force is sufficient to disperse the paint evenly without damaging the microcapsule wall.

[0026] It is conceivable that, since the fragrance microcapsules employ two different average particle sizes, after application—that is, in the wet film state before the paint is fully cured onto the substrate—the wet film is a viscoelastic system that is gradually solidifying and losing its fluidity. During this brief "window period," particles of different sizes will undergo relative motion under the combined effects of gravity, solvent evaporation convection, surface tension, and application shear forces. Specifically, due to rheological effects and the principle of Brownian motion, smaller particles are more significantly affected by collisions with liquid molecules (Brownian motion is more pronounced) and are more easily carried towards the coating surface by solvent evaporation convection. Furthermore, in the shear flow field generated by certain application methods (such as spraying), smaller particles exhibit better following characteristics, naturally forming or enhanced through directional application processes (such as spraying at a specific angle) a particle size gradient distribution of smaller at the top and larger at the bottom, thereby achieving a staged fragrance release "from small to large."

[0027] The protective varnish layer 30 is disposed on the functional coating 20. Specifically, after the functional coating 20 is fully cured, a coating without the fragrance microcapsules is applied to the surface of the functional coating 20 away from the substrate layer 10 to form a protective varnish layer. This not only seals the surface of the functional coating 20, reducing the direct exposure of the fragrance microcapsules, but also allows for control of the fragrance release rate by using materials with different air permeability, resulting in a long-lasting fragrance. The thickness of the protective varnish layer 30 is 10μm-30μm, and its film-forming material can be the same as or different from the functional paint layer of the functional coating 20, including resins and other film-forming substances, such as UV-curable resins, but interlayer adhesion must be ensured. In one embodiment of this application, the protective varnish layer 30 is a transparent polyurethane varnish with a thickness of approximately 15μm, thereby providing physical isolation and wear buffering on the surface of the functional coating 20.

[0028] Compared with existing technologies, the functional paint flooring provided by this invention achieves an integrated fragrance functional paint by uniformly dispersing the fragrance microcapsules as functional components in the formulation system during the production stage. This results in superior dispersion stability, coating adhesion, and controllable release performance. By setting the functional coating 20 and the protective paint layer 30, a multi-layer coating structure is formed by applying a protective paint layer onto the functional paint, further improving wear resistance. Different materials can be selected for the protective paint layer 30 to regulate the fragrance release rate of the functional paint. Furthermore, by selecting fragrance microcapsules with a specific particle size distribution, a particle size gradient can be naturally formed within the functional coating 20 or guided by the construction process, achieving staged fragrance release. Integrating the fragrance microcapsules with the base material to form the paint simplifies the construction process, improves the dispersion stability and adhesion strength of the microcapsules in the coating, and can be widely used for surface coating of substrates such as interior decoration, furniture, and handicrafts.
