Description

Technical Field

[0001] The invention relates to the technical field of floor repair, and in particular to a method for repairing cracks in a diamond abrasive floor. Background Art

[0002] Emery flooring is a high-performance floor material made by mixing special mineral aggregates such as emery with cement, reinforcing agents and other materials. It is constructed in the initial setting stage of concrete. After the emery is evenly spread, it is closely combined with concrete through mechanical troweling and other processes. It has extraordinary strength and can withstand the pressure and impact of heavy machinery and vehicles. It is an ideal choice for industrial plants, warehouses, parking lots and other places; it has excellent wear resistance. The high hardness of emery gives it strong wear resistance, is not easy to wear and scratch, and can maintain a good condition for a long time; it is beautiful and generous, and different colors of aggregates can be selected according to needs to add decorative effects; it is easy to clean, the surface is flat and smooth, and it is not easy to accumulate dust, which reduces the difficulty of cleaning and is conducive to maintaining environmental hygiene; it also has good resistance to chemical corrosion and aging, strong durability, long service life, and reduces frequent maintenance and replacement costs. In short, emery flooring plays an important role in many fields with its advantages of high strength, high wear resistance, beauty and easy cleaning.

[0003] Although emery flooring has many advantages, it is easy to crack and produce irregular cracks due to its low compression resistance and inadequate control of construction process and raw materials. In order to improve these shortcomings, people usually add steel mesh when pouring emery flooring concrete. Steel mesh can enhance the tensile strength of concrete, thereby improving its crack resistance, and to a certain extent, it does solve the problem of partial cracking of the ground. However, this method cannot completely prevent cracks from occurring on the ground.

[0004] When cracks appear in the emery floor, it needs to be repaired to ensure its durability and beauty. The existing technology generally cuts grooves in the cracks, and then uses anti-crack mortar or emery to directly fill the cracks and repair and smooth them. However, this method has many problems. First, the color difference is serious after the repair, the visual effect is poor, and the overall appearance is affected. Secondly, the strength is insufficient, it is easy to crack and fall off again, and the durability of the repair cannot be guaranteed. Moreover, small cracks cannot be effectively repaired. In short, this traditional repair method is not ideal and it is difficult to meet the quality requirements of the emery floor during use.

[0005] Given that diamond abrasive floors are prone to cracks and traditional repair methods are ineffective, it is necessary to solve these problems. This can not only improve the quality and durability of diamond abrasive floors, but also ensure their aesthetics, meet the use requirements of different places, and reduce later maintenance costs and resource waste. Summary of the invention

[0006] The purpose of the present invention is to provide a method for repairing cracks in diamond abrasive floors, aiming to solve the technical problems in the above-mentioned background technology.

[0007] The technical solution of the present invention is achieved in this way: The technical solution of the present application provides a method for repairing cracks in a carborundum floor, comprising the following steps: S1. Clean the surface of the diamond floor, determine the location of the cracks and mark them; S2.

Select epoxy paint of the same color as the diamond abrasive floor and spray it onto the surface of the above filling layer.

[0008] A further technical solution is to use a vacuum cleaner to absorb dust generated by the cutting when the crack is cut in step S2.

[0009] A further technical solution is to clean the V-shaped notch before filling the V-shaped notch with the filling material to remove dust and oil stains at the V-shaped notch.

[0010] A further technical solution is that the putty in step S3 is oily putty.

[0011] A further technical solution is that in step S4, when filling the V-shaped groove with filling material, a scraper is used for layered scraping and coating, and it is ensured that the thickness of the filling material in the V-shaped groove is 2-3 mm higher than the surface of the diamond abrasive floor.

[0012] A further technical solution is that when bubbles penetrate into the filling material in the V-shaped notch, a scraper must be used to scrape it flat to remove the bubbles.

[0013] A further technical solution is that in step S5, when the above-mentioned filling layer is polished, the following steps are included: First, equip the grinder with a 500-mesh grinding disc for grinding until the surface of the filling layer is flush with the surface of the diamond floor; Second, replace the 1000-mesh or 2000-mesh grinding wheel for the grinder and perform secondary grinding until the surface of the filling layer is flat and smooth.

[0014] A further technical solution is that in step S5, when the filling layer is polished, the following steps are included: First, equip the grinder with a 500-mesh grinding disc for grinding until the surface of the filling layer is flush with the surface of the diamond floor; Second, when there are pore defects on the surface of the filling layer, the filling material should be scraped and applied again to make up for it.

[0015] A further technical solution is that, in step S6, before spraying the epoxy paint, dust on the surface of the filling layer is removed.

[0016] Compared with the prior art, the technical solution of the present invention has at least the following advantages or beneficial effects: In the repair method of the present application, putty, that is, unsaturated polyester resin putty, plays a vital role. It is mainly composed of unsaturated polyester resin, filler, additives and other ingredients, and is mixed with a curing agent in a specific proportion to form a filling material. This filling material is used to fill minor pits, cracks and other defects of diamond sand floor. Atomic putty has many significant advantages. The fine gray nature enables it to fit the defects more closely and achieve seamless repair. The easy scraping feature facilitates construction operations and makes the construction process smoother. The fast drying speed greatly improves construction efficiency and saves time and cost. Strong adhesion ensures the firmness of the repair, and the durability after cracking is guaranteed by the resistance to cracking.

It effectively solves the problems of easy cracking, severe color difference and poor appearance after traditional anti-cracking mortar repair, and provides a reliable and efficient solution for the repair of diamond sand floor. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required for use in the embodiments are briefly introduced below. It should be understood that the following drawings only show certain embodiments of the present invention and therefore should not be regarded as limiting the scope. For ordinary technicians in this field, other related drawings can be obtained based on these drawings without creative work.

[0018] Figure 1 The present invention is a schematic flow chart of a method for repairing cracks in a diamond abrasive floor according to an embodiment of the present invention. DETAILED DESCRIPTION Example

[0019] Please refer to Figure 1 The present application provides a method for repairing cracks in a diamond abrasive floor, comprising the following steps: S1. First, use cleaning tools, such as brooms, vacuum cleaners or floor scrubbers, to clean the surface of the emery floor in all directions. This can effectively remove dust, debris and loose particles, creating good conditions for subsequent operations. Then carefully check the surface of the emery floor to confirm the specific location, length, width and depth of the cracks, and use a marker to mark these cracks so that targeted repairs can be carried out later.

[0020] S2. At the cracks marked on the diamond floor surface, use a handheld angle grinder equipped with a special concrete cutting disc to cut the cracks to make them appear as V-shaped notches. The width of the V-shaped notch is controlled between 5mm and 25mm, and the depth is 10mm to 20mm. However, the specific values ​​can be adjusted appropriately according to the actual size of the cracks on site. When using a handheld angle grinder for cutting, be sure to keep the angle grinder stable and advance at a constant speed to prevent the V-shaped notch from being too deep or too shallow.

[0021] S3. Carefully check the V-shaped notch to ensure that it is free of dust, oil and moisture. Next, prepare putty and curing agent to make the filling material, and mix the two in a mass ratio of 100: (1.5 - 3). During the actual on-site mixing process, the amount of curing agent can be appropriately increased or decreased according to the ambient temperature. When the temperature is lower, the amount of curing agent should be increased, and vice versa, the amount of curing agent should be reduced, but generally it should not be greater than 100:3.

[0022] It is worth noting that when making filling materials on site, they must be mixed and used immediately according to the size of the cracks. Because putty has a certain gel time, generally ranging from 5 to 15 minutes, it must be used up within the gel time to ensure the performance and effect of the filling material, providing reliable protection for the crack repair of the diamond abrasive floor, making the repaired floor more solid and durable.

[0023] S4, filling the prepared filling material into the V-shaped notch and scraping it flat; S5. After filling the V-shaped notch with filling material, wait for 2 to 3 hours for the filling material to dry and form a filling layer. Then, use a grinder to grind the surface of the filling layer. Through careful grinding, the surface of the filling layer is made flat and smooth to ensure overall integration with the diamond sand floor, thereby improving the aesthetics and practicality of the floor.

[0024] S6. According to the color of the diamond sand floor, select the same color epoxy paint to color the surface of the filling layer. When spraying, use a combination of air compressor and spray gun for construction. Adjust the air compressor pressure to ensure uniform spraying without omissions. During the spraying process, keep the spray gun at an appropriate distance and angle with the floor surface to prevent sagging or spray marks, so as to ensure the beauty and integrity of the repaired floor.

[0025] In the repair method of the present application, putty, that is, unsaturated polyester resin putty, plays a vital role. It is mainly composed of unsaturated polyester resin, filler, additives and other ingredients, and is mixed with a curing agent in a specific proportion to form a filling material. This filling material is used to fill minor pits, cracks and other defects of diamond sand floor. Atomic putty has many significant advantages. The fine gray nature enables it to fit the defects more closely and achieve seamless repair. The easy scraping feature facilitates construction operations and makes the construction process smoother. The fast drying speed greatly improves construction efficiency and saves time and cost. Strong adhesion ensures the firmness of the repair, and the durability after cracking is guaranteed by the resistance to cracking. After the repair is completed, epoxy paint is used to adjust the color according to the color of the floor, so that the repaired floor is not only not easy to crack, but also has excellent visual quality. It effectively solves the problems of easy cracking, severe color difference and poor appearance after traditional anti-cracking mortar repair, and provides a reliable and efficient solution for the repair of diamond sand floor.

[0026] In some embodiments of the present invention, when the crack cutting is performed in step S2, a vacuum cleaner is used to absorb dust generated by the cutting.

[0027] In the above embodiment, when a handheld angle grinder is used to cut cracks, a large amount of dust will be generated. At this time, the vacuum cleaner plays an important role. It can absorb the dust generated during the cutting process in time and effectively prevent the dust from spreading everywhere, which is conducive to keeping the working environment clean. This can not only provide a good working environment for construction workers, but also reduce the pollution of dust to the surrounding environment, which is practical.

[0028] In some embodiments of the present invention, before filling the V-shaped notch with a filling material, the V-shaped notch is cleaned to remove dust and oil stains at the V-shaped notch.

[0029] In the above embodiment, after the crack cutting is completed, a cleaning tool is first used to perform a preliminary cleaning of the garbage on the ground. Next, the gap and the surrounding ground dust are vacuumed with a vacuum cleaner. If there are particles in the gap that are difficult to clean, a wire brush can be used to assist in cleaning. After the vacuum cleaner is finished, the gap and the surrounding area are wiped with a cleaning cloth to ensure that there is no dust and oil. After such a meticulous cleaning process, when the filling material is filled in the V-shaped notch, the adsorption capacity of the filling material and the diamond abrasive floor can be greatly improved, making the repair effect more solid and lasting.

[0030] In some embodiments of the present invention, the putty in step S3 is oily putty.

[0031] In the above embodiment, oily putty is a commonly used multifunctional material. It is mainly composed of unsaturated polyester resin, talcum powder, styrene and other materials, and is in a paste form. Oily putty has many advantages. First, it has strong adhesion and can firmly adhere to the surface of various materials, such as metal, wood, plastic, etc., to ensure that it is not easy to fall off in different application scenarios. Secondly, it dries quickly, which can greatly shorten the construction time. Furthermore, it has good filling properties and can effectively fill in depressions, cracks and other uneven places on the surface of an object to make the surface smooth and flat. In addition, it also has certain corrosion resistance and water resistance, and can maintain stable performance in relatively harsh environments.

[0032] In some embodiments of the present invention, in step S4, when filling the V-shaped groove with filling material, a scraper is used for layered scraping and coating, and it is ensured that the thickness of the filling material in the V-shaped groove is 2-3 mm higher than the surface of the diamond abrasive floor.

[0033] In the above embodiments, the scraper is usually composed of a metal blade with high hardness (such as stainless steel) and a handle that is mostly plastic or wooden. The blade is straight, thin and sharp, and can accurately control the thickness and shape of the filling material. The handle design is ergonomic and easy to hold and operate. In gap filling, the scraper plays a significant role. It can evenly apply the filling material to the gap to ensure that every corner is fully filled, avoid voids and uneven thickness, and control the amount of material to prevent waste and excessive accumulation. At the same time, the surface after filling is trimmed to make it flat and consistent with the surrounding plane to improve the aesthetics. It has many advantages, such as simple and easy operation, low cost, durable and reusable, strong applicability and suitable for different types of filling materials, and can also improve construction efficiency, quickly complete gap filling work, and reduce construction time.

[0034] In some embodiments of the present invention, when bubbles penetrate into the filling material in the V-shaped notch, a scraper must be used to scrape it flat to remove the bubbles.

[0035] In the above embodiment, when using a scraper for scraping and coating, if bubbles seep in, they must be scraped off immediately with the scraper. This is because only in this way can the gaps be filled fully and densely, avoiding the occurrence of voids, thereby ensuring that the filling material has good adhesion to the edge of the gap and improving the construction quality.

[0036] In some embodiments of the present invention, when the filling layer is polished in step S5, a grinder equipped with a 500-mesh grinding disc is first used. Adjust the grinder to an appropriate speed, which can be set by a technician in this field according to actual conditions. Push the grinder to polish at a uniform speed and force, closely observe the polishing effect while polishing, and adjust the grinding disc pressure or machine speed in time to adapt to the specific conditions of different areas of the ground. The goal of polishing is to make the surface of the filling layer flush with the surface of the emery floor. Then observe the first polishing situation, carefully check its surface flatness and whether there are defects such as pores. If there are pore defects, putty should be scraped again to make up for it. If the surface is relatively rough, you should choose to replace the 1000-mesh or 2000-mesh grinding disc for a second polishing according to the actual situation on site until the surface is flat and smooth to ensure that the repaired emery floor is of good quality.

[0037] In some embodiments of the present invention, in step S6, dust on the surface of the filling layer is removed before the epoxy paint is sprayed.

[0038] In the above embodiment, after the filling layer is polished, a vacuum cleaner is used to vacuum the floor to remove the surface dust. For those stubborn dust, a cleaning cloth can be used to wipe it clean. Such an operation can ensure the adhesion of the paint layer and also improve the aesthetics of the repaired floor.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
