Description

Technical Field

[0001] The present application relates to the field of artistic coatings, and more specifically, to a skin-feeling artistic coating and a preparation method thereof. Background Art

[0002] As people's demands for a higher quality home environment rise, traditional paints are no longer able to meet the market's multiple demands for health and environmental protection, artistic beauty, and comfortable touch. While current artistic paints on the market have achieved breakthroughs in color and texture, they still have significant shortcomings in terms of functionality and skin feel.

[0003] Existing artistic paints have a simple touch. Most paints only rely on adding wax powder or silicone oil to achieve a smooth feel, lacking the resilience and fineness of skin; or, the artistic expression is insufficient, and pearlescent materials such as synthetic mica lack a three-dimensional sense of layering. Summary of the Invention

[0004] The invention of this application aims to improve the skin feel of artistic paint and increase its adhesion strength.

[0005] In order to achieve the above-mentioned invention objectives, the present application provides a skin-feeling artistic paint and a preparation method thereof. The skin-feeling artistic paint is named "Milan Soft Yarn" and specifically adopts the following technical solutions: In a first aspect, the present application provides a skin-feel artistic paint, which comprises the following components, calculated by weight percentage: 20-40% skin-feel resin; 10-30% emulsion; 3-10% hand-feel powder; 0.5-2% formaldehyde removal additive; 1-5% negative ion powder; 10-20% natural pearl shell color flakes; 1-3% functional additive; 5-10% water; The skin-feeling resin is any one of an organic silicon modified resin, a polyurethane resin and an acrylic modified resin.

[0006] Furthermore, the skin-feeling resin is a mixture of an organic silicon-modified acrylic resin and a polyurethane elastic resin, and the weight ratio of the organic silicon-modified acrylic resin to the polyurethane elastic resin is 1:(0.4-0.6).

[0007] Furthermore, the preparation method of the skin-feel resin is: mixing a silicone-modified acrylic resin and a polyurethane elastic resin, adding 1 to 2% of a silane coupling agent KH-550 accounting for the total weight of the resin, and then adding 0.1 to 0.5% of a non-ionic wetting agent BYK-349 accounting for the total weight of the resin, stirring and mixing at a speed of 300 to 500 rpm to obtain a skin-feel resin.

[0008] Furthermore, the emulsion is a mixture of pure acrylic emulsion and acrylic elastic emulsion, and the weight ratio of pure acrylic emulsion to acrylic elastic emulsion is (2-3):1.

[0009] Furthermore, the hand-feeling powder is a mixture of silica aerogel and organosilicon micropowder, and the weight ratio of silica aerogel to organosilicon micropowder is (1-1.5):1.

[0010] Furthermore, the formaldehyde removal auxiliary agent is nano titanium dioxide.

[0011] Furthermore, the negative ion powder is tourmaline powder.

[0012] Furthermore, the functional additives include one or more of a dispersant, a defoaming agent, a thickener, a pH regulator, and a preservative.

[0013] Furthermore, the diameter of the natural pearl shell colored flakes is 0.6-2 mm.

[0014] In a second aspect, the present application provides a method for preparing the above-mentioned skin-feeling artistic paint, comprising the following steps: Step 1: Add the functional additive into water and stir to mix; Step 2, adding hand-feeling powder to the mixed system and stirring to mix; Step 3, adding the emulsion and skin-feeling resin to the mixed system and stirring to mix; Step 4, adding natural pearl shell colored flakes to the mixed system and stirring to mix thoroughly; Step 5: add the formaldehyde removal auxiliary agent and negative ion powder to the mixed system, stir and mix well to obtain the product.

[0015] In summary, this application has the following beneficial effects: 1. The skin-feel art paint of this application has a good skin-feel experience. Through the synergistic effect of the two resins, the silicone-modified acrylic resin provides a silky surface and reduces surface friction, and the polyurethane elastic resin imparts a slightly elastic rebound effect, which can simulate the touch of human skin.

[0016] 2. This application is formulated with silica aerogel. On the one hand, silica aerogel can reduce surface energy and enhance slipperiness. On the other hand, organosilicon micropowder fills the microporous structure to avoid stickiness of the coating and improve the feel.

[0017] 3. The natural pearl shell colored sheet of the present application retains the natural layered structure and presents an iridescent color-changing effect. Its color can be customized, and the coarse particle design enhances the three-dimensional effect of the coating.

[0018] 4. The skin-feel artistic paint of this application has achieved a triple breakthrough in touch, functionality and artistry through the optimization of materials and processes, and is suitable for high-end homes, commercial spaces and healthy buildings. DETAILED DESCRIPTION

[0042] Performance testing 1. Skin feel test The friction coefficient is tested according to ASTM D1894. The dynamic friction coefficient (μ) of the coating is measured. The lower the value, the smoother the touch. The resilience was tested according to ISO 3386-1. After applying 5N pressure and removing it, the deformation recovery rate (%) of the coating was recorded.

[0043] Friction coefficient / μ Rebound rate / % Example 1 0.15 85 Example 2 0.18 82 Example 3 0.14 86 Example 4 0.16 83 Example 5 0.13 86 Example 6 0.12 90 Example 7 0.11 92 Example 8 0.11 94 Example 9 0.14 86 Example 10 0.14 84 Example 11 0.11 86 Example 12 0.11 86 Example 13 0.12 85 Comparative Example 1 0.20 35 Comparative Example 2 0.20 40 Comparative Example 3 0.22 54 Comparative Example 4 0.14 83 As can be seen from the above table, in Examples 6-8, the skin feel of the artistic coating is effectively improved through the synergy of the two resins, with a lower friction coefficient and a higher rebound rate.

[0044] In Examples 1, 9, and 10, the ratios of the emulsions are different. When the ratio of pure acrylic emulsion to acrylic elastic emulsion is 2:1, the skin-feel artistic paint prepared in Example 9 has better performance.

[0045] In Examples 1, 11, and 12, the ratio of the hand-feeling powder is different, among which when the ratio of silica aerogel to organosilicon micropowder is 1.2:1, the skin-feeling artistic coating prepared in Example 12 has better performance.

[0046] Comparative Example 1 uses a single acrylic resin, and the resulting artistic coating has a stiff touch and poor functionality.

[0047] In Comparative Example 4, mica powder is used instead of natural pearl shell colored flakes. Although the skin feel performance does not change significantly, it can be seen from observation that the artistry is insufficient and there is no three-dimensional effect.

[0048] 2. Physical performance test Adhesion is tested using the cross-hatch method in GB / T 9286-1998, with a scale of 0-5, where 0 is the best. The weather resistance was tested according to GB / T 1865-2009, and QUV accelerated aging was performed for 500 h to observe the chalking.

[0049] Adhesion / Grade Weather resistance (500h) Example 1 0 No powdering Example 2 0 No powdering Example 3 0 No powdering Example 4 0 No powdering Example 5 0 No powdering Example 6 0 No powdering Example 7 0 No powdering Example 8 0 No powdering Example 9 0 No powdering Example 10 0 No powdering Example 11 0 No powdering Example 12 0 No powdering Example 13 0 No powdering Comparative Example 1 1 Slightly powdery Comparative Example 2 1 Slightly powdery Comparative Example 3 2 Obvious powdering Comparative Example 4 1 Slightly powdery It can be seen from the above table that the skin-feel artistic coating of this application has significantly improved its adhesion and weather resistance through the optimization of materials and processes.
