Description

Technical Field

[0001] This invention relates to the field of coatings, and more specifically, to a sand-on-sand art coating with a travertine texture that can be applied and its preparation method. Background Technology

[0002] As people's living standards continue to improve, more and more consumers have higher requirements for the aesthetics of their home walls, no longer limited to traditional latex paint and plain white walls. As a result, diverse and unique artistic paints have gradually emerged, which can be personalized according to individual preferences and spatial needs to meet the decoration needs of different styles and functional spaces.

[0003] As consumers increasingly seek the effects of natural stone, travertine-effect artistic coatings have gradually emerged on the market. This effect evokes a sense of warmth, rich texture, and clear stripes, often giving decorated buildings a strong cultural and historical charm. Furthermore, due to its unique texture and special porous structure, it possesses excellent decorative properties and is highly favored by consumers.

[0004] Currently, most methods on the market achieve this effect by applying a thick, sand-containing coating to the surface and then tapping it with a tool after it dries to create a round pit effect; or by using a cleaver to carve out the texture. However, the texture obtained by these methods is not natural enough and is time-consuming and laborious.

[0005] Therefore, there is a need to develop a sand-on-sand art coating with a travertine texture that can be applied. The travertine texture is naturally formed, making construction convenient and eliminating the need for artificial texture creation. Summary of the Invention

[0006] The purpose of this invention is to provide a sand-on-sand art coating with a travertine texture that can be applied. It has a special porous structure, which can create an artificial travertine effect without special tools and is easy to apply.

[0007] Another objective of this invention is to provide a method for preparing a sand-on-sand art coating with a travertine texture that can be applied. By increasing the toughness, strength, and volume solids content of the colored dots and controlling the filler composition, the method ensures that the colored dots are not easily broken or deformed during the application process.

[0008] The technical problem solved by this invention is achieved by the following technical solution.

[0009] On one hand, embodiments of the present invention provide a sand-bag art coating with a travertine texture that can be applied, comprising the following steps: S1, Preparation of base paint A: Mix water, wetting agent, defoamer and antifreeze at a stirring speed of 300 r / min for 3 minutes until well mixed; Slowly add hydroxyethyl cellulose and hydrophobically modified hydroxyethyl cellulose and stir for 5 minutes to mix well. Then slowly add pH adjuster and disperse at 1500 r / min for 25 minutes. Reduce the rotation speed to 1000 r / min, add bactericide, 10 wt% polyvinyl alcohol solution, and 50-70 mesh glass sand, and stir for 20 min; Add 10wt% protective adhesive solution, adjust the speed to 1500r / min, and disperse for 25min to obtain base paint A; S2, Granulation: Add 5wt% protective colloid solution to the dispersion tank, then add the base paint A prepared in step S1 to the protective colloid solution. After pre-cutting, granulate it in a disperser, gradually increase the speed, and stir until the particle size of the colored dots is 1-1.5mm to obtain colored dots A. S3, Preparation of continuous phase B: Add 5wt% protective colloid solution to the dispersion tank and stir at 250 rpm; then add bentonite and adjust the speed to 800 rpm, stirring for 10 minutes; then add antifreeze, dispersant, film-forming aid, and defoamer and stir for 5 minutes; then add heavy calcium carbonate powder and adjust the speed to 1200 rpm, dispersing for 15 minutes; adjust the speed to 800 rpm, add acrylic emulsion, 50-70 mesh natural sand, 70-100 mesh natural sand, and bactericide, stirring for 3 minutes; then add the thickener solution after alkali swelling and stir to disperse for 15 minutes. S4, Preparation of coating: Add continuous phase B to the mixing tank, then add colored particles A, and mix at low speed for 10 minutes to obtain the coating.

[0010] In some embodiments of the present invention, in step S1, the base paint A comprises the following raw materials by weight: 40-60 parts water, 0.1-0.5 parts wetting agent, 0.1-0.5 parts defoamer, 0.5-0.8 parts antifreeze, 1-2 parts hydroxyethyl cellulose, 1-2 parts hydrophobically modified hydroxyethyl cellulose, 0.1-0.5 parts bactericide, 5-15 parts polyvinyl alcohol solution, 10-15 parts glass sand, and 10-15 parts protective colloid solution.

[0011] In some embodiments of the present invention, in step S2, the mass ratio of 5wt% protective adhesive solution to base paint A is 1:3. In some embodiments of the present invention, continuous phase B comprises the following raw materials by weight: Protective colloid solution 10-20 parts, bentonite 0.5-1 parts, antifreeze 0.1-0.5 parts, dispersant 0.1-0.5 parts, film-forming aid 0.1-0.5 parts, defoamer 0.1-0.5 parts, heavy calcium carbonate powder 35-50 parts, acrylic emulsion 5-15 parts, 50-70 mesh natural sand 5-20 parts, 70-100 mesh natural sand 10-25 parts, bactericide 0.1-0.5 parts, thickener solution 0.1-0.5 parts. In some embodiments of the present invention, in step S3, the mass ratio of colored dot A to continuous phase B is (1-5):(95-99).

[0012] In some embodiments of the present invention, the protective adhesive solution is a lithium magnesium silicate solution.

[0013] In some embodiments of the present invention, the 10wt% protective adhesive solution comprises, by mass percentage, the following raw materials: 89.7% water, 0.3% bactericide, and 10% lithium magnesium silicate; The 5wt% protective adhesive solution comprises the following raw materials by mass percentage: 94.7% water, 0.3% bactericide, and 5% lithium magnesium silicate.

[0014] A sand-on-sand art coating with a travertine texture that can be applied is prepared by the above-described method.

[0015] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: The coating provided by this invention has a unique porous structure, eliminating the need for special tools to create an artificial perforated effect. It is easy to apply. The unique porous structure originates from the pits left by the movement of the colored dots during the application process, as well as from the shrinkage of the dots after drying and the pits left after sanding. It is also color-adjustable. The colored dots are highly resilient, making them easy to apply and less prone to breakage. After drying, the dots are transparent and do not form a film. In step S2, the volume solids content of the colored dots is between 10-15%, and the mass solids content is between 23-28%.

[0016] Specifically, by using hydrophobically modified hydroxyethyl cellulose and a suitable combination of lithium magnesium silicate and cellulose, a more resilient colored dot can be obtained. Increasing the amount of these components allows for a more complete "gel" reaction. The hydrophobically modified hydroxyethyl cellulose and lithium magnesium silicate form a "gel," which itself associates with wetting agent micelles, enhancing its resistance to pressure and giving the colored dots a certain strength. Simultaneously, using a high-hydroxyl, high-molecular-weight polyvinyl alcohol solution in conjunction with this system results in a more robust and complete three-dimensional network structure, stronger water-binding ability, and more elastic "gel." When using this coating, deformation occurs during application, but the shape recovers significantly upon removal of the trowel, effectively isolating the colored dots from the continuous phase.

[0017] The combination of cellulose and lithium magnesium silicate protective adhesive gives the colored dots better strength. On this basis, the addition of polyvinyl alcohol solution makes the colored dots even stronger and gives them excellent elasticity. On the other hand, the low volume solids content of the colored dots in the base paint A results in a high degree of volume shrinkage of the colored dots during the film formation process, which makes it impossible for them to adhere to the continuous phase material, thus forming sand-containing pits. The glass frit in the sand-containing pits is then removed by a grinding process to form the pits.

[0018] On the other hand, using glass sand to fill the colored dots allows the dots to deform significantly when the putty knife excessively presses them during the troweling process. The glass sand then comes into contact with the putty knife, reducing the stress on the colored dots. At the same time, because the glass sand itself is relatively smooth, the coefficient of friction between it and the putty knife is low, thus reducing the pushing force of the putty knife on the colored dots during the troweling process, which has a "force-relieving" protective effect.

[0019] The coating provided by this invention is tintable because the colored dots do not contain powder or other substances with covering power. Once the colored dots are completely dry, they become transparent. Due to the protective effect of the protective adhesive on the colored dots, the color is adjusted to match the continuous phase color. The color paste will not seep into the colored dots, so the colored dots do not affect the overall hue, and there will be no phenomenon of colored dots having color, because the colored dots are transparent after drying and will disappear with sanding.

[0020] The continuous phase contains a high amount of protective colloid, which makes the colored dots stable during storage and construction. The bentonite thickening and high powder content make the coating easy to apply, stable in shape, and with less movement of colored dots. The effect is also smooth and fine in areas without holes. The coating uses a combination of coarse and fine sand. The coarse sand can control the thickness of the product application, i.e., the wet film thickness, while the finer sand can reduce the slippage of the coarse sand and reduce the damage to the colored dots during the application process. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply. Reagents or instruments whose manufacturers are not specified are all conventional products that can be purchased commercially.

After pre-cutting, granulate it in a disperser, gradually increasing the speed and stirring until the particle size of the colored dots is 1-1.5mm to obtain colored dots A. In this step, colored dots A are generated from base paint A. When granulating in the disperser, the base paint is simply cut into particles of different sizes while ensuring that they are incompatible, thus obtaining granular colored dots A.

S4, Preparation of coating: Add continuous phase B to the mixing tank, then add colored particles A, and mix at low speed for 10 minutes to obtain the coating.

[0026] In step S2, the mass ratio of 5wt% protective adhesive solution to base paint A is 1:3. Continuous phase B, by weight, comprises the following raw materials: Protective colloid solution 10-20 parts, bentonite 0.5-1 parts, antifreeze 0.1-0.5 parts, dispersant 0.1-0.5 parts, film-forming aid 0.1-0.5 parts, defoamer 0.1-0.5 parts, heavy calcium carbonate powder 35-50 parts, acrylic emulsion 5-15 parts, 50-70 mesh natural sand 5-20 parts, 70-100 mesh natural sand 10-25 parts, bactericide 0.1-0.5 parts, thickener solution 0.1-0.5 parts. In step S3, the mass ratio of colored dot A to continuous phase B is (1-5):(95-99).

[0027] The protective adhesive solution is a lithium magnesium silicate solution. A 10wt% protective adhesive solution, by mass percentage, comprises the following raw materials: 89.7% water, 0.3% bactericide, and 10% lithium magnesium silicate. The 5wt% protective adhesive solution comprises the following raw materials by mass percentage: 94.7% water, 0.3% bactericide, and 5% lithium magnesium silicate.

[0028] A sand-on-sand art coating with a travertine texture that can be applied is prepared by the above-described method.

[0029] Traditional travertine effect artistic coatings are applied by smearing a thick paste similar to travertine onto the wall, allowing it to dry and level, and then creating holes in the surface using a trowel or special tools. This process is time-consuming and labor-intensive, and the resulting texture is not natural. The specific steps involve smearing, leveling, creating holes, sanding, and applying a topcoat. The product in this patent eliminates the need for the hole-creating step. The process involves smearing, leveling, sanding, and applying a topcoat, resulting in a naturally formed texture without the need for artificial texturing. The specific design principle is as follows: the hole effect is achieved through two processes. The first process involves the relatively large and resilient paint dots. During the application process, sliding pits appear as the paint smears. The paint dots slide under pressure, but their strong elasticity and toughness prevent them from breaking. This deformation causes the paint smear to move a certain distance before stopping and detaching from the smear. As the number of applications increases, the paint on the wall becomes more compacted, making the paint dots less prone to sliding. The elastic deformation also helps prevent breakage. The second process involves the paint dots drying, during which the moisture gradually evaporates and the volume shrinks by 85-90%. The solid substances inside the paint dots are not connected to the continuous phase outside the paint dots. Most of the remaining solid substances are sand. When sanding, the sand is removed because the paint dots have no adhesive, forming pits. This process can be completed simply by normal sanding.

[0030] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0031] Example Based on the proportions in Table 1-7, prepare the coating according to the following steps.

[0032] S1, the production process of colored dot base paint A: Mix the water, wetting agent, defoamer, and antifreeze in the first stage for 3 minutes at a stirring speed of 300 r / min.

[0033] Slowly add hydroxyethyl cellulose and hydrophobically modified hydroxyethyl cellulose and stir for 5 minutes to mix evenly. Then slowly add pH adjuster and adjust the speed to 1500 r / min as appropriate, and disperse for 25 minutes.

[0034] Reduce the rotation speed to 1000 r / min, gradually add bactericide, 10 wt% polyvinyl alcohol solution, and 50-70 mesh glass sand, and stir for 20 min.

[0035] Add a 10% concentration of protective colloid solution, adjust the rotation speed to 1500 r / min, disperse for 25 minutes, and then discharge.

[0036] S2 granulation stage: Weigh 25 parts by weight of a 5% concentration protective colloid solution into a dispersion tank. Weigh 75 parts by weight of the base paint A and add it to the protective colloid solution. After pre-cutting, granulate the mixture using a disperser. Start with a speed of 300 r / min and gradually increase the speed by 200 r / min. After gradient stirring for 3 minutes, observe the size of the colored dots. Stir until most of the colored dots are 1.5 mm in size to obtain colored dot A.

[0037] Production process of S3 continuous phase B: Add 5wt% protective colloid solution to the dispersion tank, rotate at 250 rpm, slowly add bentonite, then adjust the speed to 800 rpm and stir for 10 minutes. Then slowly add antifreeze, dispersant, film-forming aid, and defoamer and stir for 5 minutes. Next, slowly add 325 mesh heavy calcium carbonate powder, adjust the speed to 1200 rpm and disperse for 15 minutes. Adjust the speed to 800 rpm and slowly add emulsion, 50-70 mesh natural sand, 70-100 mesh natural sand, and bactericide. Stir for 3 minutes. Slowly add alkali swelling thickener solution diluted with water (1:1 with water) and stir and disperse for 15 minutes.

[0038] The production process for the S4 finished product formula is as follows: First, add continuous phase B to the mixing tank, then slowly add the colored dots A prepared in step S2, and mix at low speed for 10 minutes.

[0039] The priority for each raw material is as follows: Ethylene glycol is the preferred antifreeze agent; The hydroxyethyl cellulose ether used is Ashland 250HHBR; The hydrophobically modified hydroxyethyl cellulose ether used is Ashland's HE 3KB; The wetting agent used is Clariant 407; The heavy calcium carbonate powder used is ultrafine calcium carbonate CC918 from Guangxi Zhuang Autonomous Region Hezhou Kelong Powder Co., Ltd. The 50-70 mesh glass sand used is Zhaotong's 50-70 mesh solid glass microspheres; The preferred pH adjuster is Dow's AMP-95; The acrylic emulsion chosen is Showa emulsion AP-4765; The polyvinyl alcohol used is polyvinyl alcohol (2699) from Yinjie Chemical Co., Ltd.

[0040] Table 1

[0041] The formulation of the 10wt% lithium magnesium silicate protective adhesive solution is shown in Table 2.

[0042] Table 2

[0043] The formulation of the 5wt% lithium magnesium silicate protective adhesive solution is shown in Table 3.

[0044] Table 3

[0045] The formulations (parts by weight) and test results of each base paint color point A are shown in Table 4.

[0046] Table 4

[0047] In Table 5, the test method for the volume shrinkage rate of colored dots is as follows: Volume shrinkage rate = (wet film volume - dry film volume) / wet film volume * 100%, and the specific gravity is tested. Weigh 10 grams of base paint A, calculate the volume before drying, place the weighed base paint A at 25℃ and 50% humidity for 48 hours, add the dried base paint A to a 10mL test tube with a scale, add 5g of water, observe the scale (because the dried material is mainly glass sand, the dried material will sink into the water), and obtain the dry film volume.

[0048] The formulations of each continuous phase B are shown in Table 5.

[0049] Table 5

[0050] The formulations of each coating are shown in Table 6.

[0051] Table 6

[0052] The formulations of the comparative coatings are shown in Table 7.

[0053] Table 7

[0054] In Table 7, the formulation A-1 was used in Comparative Example 8, but in S2, the average particle size of colored dots A was controlled to be 2 mm by the dispersion rate. The formulation A-1 was used in Comparative Example 9, but in S2, the average particle size of colored dots A was controlled to be 0.5 mm by the dispersion rate.

[0055] Among them, the hole effect: observe whether the density is uniform, the size is uniform, the shape of the hole, and whether there are any residues in the pits after polishing; Grinding performance: Observe whether the remaining shrinkage material in the pit is easy to grind and whether the glass sand can be removed by normal grinding. Construction performance: Observe the toughness and strength of the colored dots during construction, the shape change of the colored dots under stress, whether they break during application, the integrity of the colored dots, and whether the colored dots have resilience.

[0056] From Tables 6 and 7, we can conclude that: Comparative Example 1: The emulsion in A-3 is an acrylic emulsion. Because an emulsion with better film-forming properties was used, the film adhesion was strong after the colored dots shrank, and the residue was difficult to sand.

[0057] Comparative Example 2: In A-4, the amount of polyvinyl alcohol used was 20 parts. The polyvinyl alcohol content was too high, and the film-forming ability was too good, which made it difficult to polish the residue after the colored dots shrank.

[0058] In Comparative Example 3: A-5, the amount of hydroxyethyl cellulose and hydrophobically modified hydroxyethyl cellulose was relatively small, resulting in insufficient toughness of the colored dots. This caused the colored dots to break easily during application, leading to poor pitting effects.

[0059] Comparative Example 4: A-6 contains too little glass sand, making the colored dots relatively easy to break during construction, thus failing to resist the scraping force.

[0060] Comparative Example 5: A-7 does not contain wetting agent, which leads to a decrease in the cross-linking density of the colored dots, a decrease in elasticity, and easy breakage during application.

[0061] Comparative Example 6: Because the amount of 50-70 mesh natural coarse sand in continuous phase B-2 was 5 parts, the amount of coarse sand was too small, resulting in excessive stress on the colored dots during construction, which made the colored dots relatively fragile.

[0062] Comparative Example 7: Because there is no protective colloid in the continuous phase B-3, there is too little protective colloid on the outside of the colored dots when they are added. During the mixing process, the colored dots are easily broken when they are rubbed by sand. There is no magnesium lithium silicate to fill the gap, which leads to the migration of colored dot materials and continuous phase materials, resulting in a decrease in the toughness of the colored dots and breakage during the mixing process.

[0063] In Comparative Example 8: A-1, the particle size of the colored dots was too large, and the dots were subjected to excessive force during construction, resulting in breakage. Furthermore, the pits were irregular and unnatural.

[0064] Comparative Example 9: A-1 shows that the colored dots are too small, the density is too high, and the pits are unnatural.

[0065] The embodiments described above are some, but not all, embodiments of the present invention. The detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
