Preparation method, fabric and application of embroidered fabric with concrete surface pattern engraving

Abstract

A preparation method of an embroidered fabric with a concrete surface pattern engraving. First, impregnate the yarn in an etching component solution and dry it to obtain etched lines. Then, make core particles with a core material. Next, wrap a wall material around the core particles to obtain microcapsules. Then, load the microcapsules on a base fabric. Then, embroider the etched lines on the base fabric loaded with microcapsules through an embroidery process to obtain a fabric. During application, first contact the side of the fabric with microcapsules and an embroidered pattern with freshly mixed concrete. The core material components in the microcapsules participate in the hydration reaction of the cementitious material system. In the area in contact with the etched fibers, the setting time of the cement is extended due to the retardation effect of the etching component. After the concrete has finally set, remove the fabric, and then rinse the concrete surface in contact with the embroidered pattern with a high-pressure water gun to remove the un-set cement paste due to the action of the etching component. This design can achieve advantages such as strong durability, low operation difficulty, and diverse patterns.

Description

Technical Field

[0001] The invention relates to a concrete material surface patterning technology, belongs to the field of concrete surface patterning, and in particular to a preparation method of a concrete surface patterned embroidery fabric, the fabric and application. Background Art

[0002] Concrete is a common building material, widely used in construction, roads, bridges, tunnels and other engineering fields. However, the surface of traditional concrete materials is usually monotonous and lacks decorativeness and artistic sense. In order to meet people's demand for decorative surface of building materials, various concrete material surface patterning technologies have gradually developed.

[0003] At present, concrete surface patterning technologies mainly include the following:

[0004] Electrochemical etching technology: This technology uses chemical solutions and electrochemical reactions to depict patterns on the concrete surface. Electrochemical etching technology can achieve different surface effects by controlling parameters such as solution concentration, temperature and current density;

[0005] Spraying technology: This technology is to spray pigments or texture materials on the concrete surface to form a pattern. Spraying technology can achieve more complex pattern effects, but its durability is poor and it is easily affected by the external environment;

[0006] Film pasting technology: This technology is to paste special films on the concrete surface to form different pattern effects. Film pasting technology can achieve various complex pattern effects, but the durability of the film is also poor and easily affected by the external environment;

[0007] Engraving technology: This technology uses mechanical or manual engraving to carve patterns on the concrete surface. Engraving technology can achieve very detailed pattern effects, but the process is complicated and the cost is high.

[0008] As can be seen from the above, although the existing concrete material surface patterning technology can achieve a certain degree of decorative effect, it still has the following three defects:

[0009] Durability issues: The durability of pigments and film materials in current concrete surface patterning technologies, such as spraying and film pasting, is poor and they are easily affected by external environmental factors such as oxidation, ultraviolet rays, and pollution, causing the color and pattern to lose their beauty.

[0010] Difficult to operate: Engraving technology requires professional skills and equipment, is difficult to construct, and is costly. It is also not suitable for large-scale construction. Although electrochemical etching technology can produce a variety of complex surface effects, it requires high control technology for chemical solutions and is difficult to operate.

[0011] Single effect: The current concrete surface patterning technology has a relatively single effect and can only achieve limited changes in texture, pattern and color. However, it is difficult for current technology to meet the needs of more diversified and personalized designs.

After the embroidery process is completed, the concrete surface pattern engraved embroidery fabric can be obtained.

[0027] In the first step:

[0028] When solute A is used, the mass ratio of solute to water is 0.1%-1.0%;

[0043] A fabric is a product of the method for preparing a fabric with embroidery and pattern carved on a concrete surface, namely, a fabric with embroidery and pattern carved on a concrete surface.

[0044] An application of a fabric, wherein the fabric is the above-mentioned fabric, and the application includes any one of the following:

[0045] Method 1: First, pour freshly mixed concrete in the mold, and then cover the surface of the concrete with the side of the fabric with microcapsules and embroidery patterns, so that the slurry in the concrete is in contact with the etching components and microcapsules on the fabric. After the concrete is finally set, the fabric is removed, and then the concrete surface in contact with the embroidery pattern is washed with a high-pressure water gun to remove the cement slurry that has not solidified due to the action of the etching components, so that a pattern with a carving effect can be formed on the concrete surface;

[0046] Method 2: First, lay the fabric flat and fix it on the inner surface of the mold, and then pour fresh concrete into the mold. After pouring, the slurry in the concrete comes into contact with the etching components and microcapsules on the fabric. After the concrete is finally solidified, remove the template that constitutes the mold, then peel off the fabric, and then use a high-pressure water gun to rinse the concrete surface that is in contact with the embroidery pattern to remove the cement slurry that has not solidified due to the etching components, so that a pattern with a carving effect can be formed on the concrete surface.

[0047] In the method 1, after the slurry in the concrete comes into contact with the etching components and microcapsules on the fabric, a NaOH solution with a pH of ≥11 is evenly sprayed on the surface of the fabric, and then the concrete is waited for final setting;

[0049] The time for peeling off the fabric is 1 to 12 hours after the final setting of the concrete and before the retarding effect of the etching component fails.

[0050] Compared with the prior art, the present invention has the following beneficial effects:

[0051] 1. The present invention discloses a method for preparing a concrete surface pattern-carving embroidery fabric, a fabric and an application thereof. The method comprises the following steps: firstly, immersing a yarn in an etching component solution to obtain etching lines, then making a capsule core material into capsule core particles, then wrapping a capsule wall material around the outside of the capsule core particles to obtain a blank capsule, then performing blast drying on the blank capsule to obtain microcapsules dispersed from each other, then loading the microcapsules on the bottom surface of a base cloth through a binder, and then embroidering a pattern on the bottom surface of the base cloth loaded with the microcapsules using an embroidery process to obtain the concrete surface embroidery pattern-carving fabric. When used, the side of the fabric with microcapsules and embroidery patterns is first brought into contact with fresh concrete, and the etching components and microcapsules carried on the fabric are brought into contact with the concrete. Subsequently, the etching components penetrate into the surface layer of the concrete and delay the hydration reaction of the cement on the surface layer (the etching components have a delaying effect on the hydration reaction of cement binder materials and can extend the final setting time of the concrete by 2-24 hours), and form a granular frosted surface on the surface of the concrete; at the same time, the capsule wall material of the microcapsule dissolves and breaks under the action of alkali in the concrete slurry (the capsule wall material dissolves for 1-10 hours under an environment of pH ≥ 11), so that the capsule core material component contacts the concrete and penetrates into it, and the capsule core material component undergoes an infiltration crystallization reaction with the gel material, that is, the chemical components in the capsule core material enter the surface layer of the concrete and react with the free calcium ions and water molecules in the concrete, thereby forming a dense crystalline surface structure on the concrete surface, thereby enhancing the hardness, density and durability of the concrete surface. It can be seen from the entire reaction process that not only are the operating tools simple and easy to obtain, the labor intensity is low, and the operating difficulty is reduced, but also the embroidery patterns are diverse, which can achieve more diversified, personalized, and three-dimensional surface pattern design requirements. In addition, the hydration delay reaction and the infiltration crystallization reaction have a good collaborative effect. The hydration delay reaction provides sufficient reaction time and reaction basis for the infiltration crystallization reaction, which is conducive to improving the formation effect of the crystal body, and the infiltration crystallization reaction can improve the strength and density of the frosted surface, thereby improving the decorativeness and durability of the pattern formed on the concrete surface. Therefore, the present invention can simultaneously achieve the advantages of strong durability, low operating difficulty, and diversified patterns.

[0052] 2. In the preparation method, fabric and application of a concrete surface pattern-carving embroidery fabric of the present invention, the solute of the etching component solution is any one of solute A, solute B, solute C, solute D, solute E, solute F, solute G, and solute H. This technical feature not only enables the design to have a relatively large selection range to meet different application requirements, but also can obtain stronger adjustability, such as the application effect and application amount of each solute are different, thereby obtaining a richer pattern-carving effect. Therefore, the present invention not only has a wide range of applications, but also has strong adjustability.

[0053] 3. In the preparation method, fabric and application of a concrete surface pattern engraving embroidery fabric of the present invention, the capsule wall material dissolves in an environment of pH ≥ 11. The design makes it possible for the capsule wall to gradually break in an alkaline environment after the microcapsule contacts the concrete, so that the capsule core particles inside the capsule contact the concrete to perform an infiltration crystallization reaction, without any external force, and the operation is very convenient. Therefore, the operation convenience of the present invention is relatively strong.

[0054] 4. In the preparation method, fabric and application of a concrete surface pattern engraving embroidery fabric of the present invention, when the etching components and microcapsules are loaded on the base fabric, the microcapsules are first loaded on the bottom surface of the base fabric through a binder, and then the etching lines are embroidered on the bottom surface of the base fabric loaded with microcapsules through an embroidery process to form a pattern. It can be seen that the arrangement of the microcapsules is arranged before the embroidery process. This design can ensure that the microcapsules are fully loaded on the base fabric to achieve subsequent penetration crystallization reactions, and can also avoid destroying the microcapsules through the embroidery process, such as selecting a suitable embroidery needle (the size of the embroidery needle The shape should be suitable for the thickness of fabric and yarn, avoid using too large or too thick needles to avoid damaging microcapsules), control the embroidery strength (when performing embroidery operations, the strength should be controlled to avoid piercing the back of the fabric with the needle as much as possible to avoid piercing the microcapsules), and limit the embroidery order (when performing embroidery operations, attention should be paid to the order of embroidery, try to embroider the area around the microcapsules first, and finally embroider the part above the microcapsules to avoid accidentally piercing the microcapsules with the needle during embroidery), so as to fully ensure the smooth progress of the hydration delay reaction and the penetration crystallization reaction. Therefore, the load effect of the present invention is better, which is conducive to improving the depiction effect of concrete. BRIEF DESCRIPTION OF THE DRAWINGS
