[0018] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by terms such as “front”, “up”, “down”, “left”, “right”, “vertical” and “horizontal” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0019] The following is combined with Figure 1-5 The present invention is further described.

[0020] In order to solve the problems existing in the background technology, the present application proposes the following technical solutions: an integrated floor diamond grinding disc, comprising a grinding disc body 1, the grinding disc body is a circular or fan-shaped structure, and also comprising a base 3, the grinding disc body 1 is mounted on the base 3, a metal sheet is embedded in the base 3, and a plurality of sets of embedding grooves 2 are provided on the grinding disc body 1, and a nylon non-hook reinforced base fabric is embedded in the embedding groove 2. The nylon non-hook reinforced base fabric is embedded in the embedding groove 2 by hot pressing, and the depth is 2.5mm;

[0021] In a further design, the grinding disc body 1 is a circular or polygonal structure, and in this embodiment is a polygonal structure, and the base 3 is provided with a mounting groove 4, and the mounting groove 4 protrudes from the base 3, and the grinding disc body 1 is coated with adhesive and embedded in the mounting groove 4 of the base 3. When the nylon non-hook reinforced base fabric is installed by hot pressing, the hot pressing temperature is 185°C, the pressure is 1.96MPa, and the hot pressing time is 30 minutes.

[0022] The base body 3 is made of a mixture of nylon and glass fiber, so that the strength of the base body 3 is increased.

[0023] The above technical solution is explained as follows:

[0024] The matrix 3 is made of nylon and glass fiber, which can significantly enhance the strength and rigidity of nylon. Compared with pure nylon, its tensile strength can be increased by 50%-200%, and its bending strength is also significantly increased, which enables it to withstand greater external forces;

[0025] During assembly, the bonding surface of the grinding disc body 1 is cleaned to remove factors that affect the bonding effect, such as oil stains and impurities, and is wiped with a special industrial cleaner and then dried.

[0026] Select a suitable high-performance adhesive, preferably epoxy resin adhesive, and mix it according to the requirements of the product manual to ensure that the adhesive's performance indicators such as viscosity and curing time meet the assembly requirements.

[0027] Apply the prepared adhesive evenly on the bonding surface of the grinding disc body 1, and control the coating thickness within the range of 0.5 mm to ensure the reliability of bonding and avoid excessive adhesive waste or affect the balance of the grinding disc body 1. Quickly and accurately embed the grinding disc body 1 coated with adhesive into the mounting groove 4 of the substrate 3, and then stand it for 24 hours under the specified curing environment (temperature > 25, humidity < 20), wait for the adhesive to fully cure, and complete the assembly of the integrated floor diamond grinding disc body 1.

[0028] Appearance inspection: Check whether the bonding area between the grinding disc body 1 and the base 3 is tight, free of bubbles and cracks; check whether the key parts such as the mounting groove 4 are processed in accordance with the specifications, and whether there are defects such as burrs and deformation; confirm that the overall appearance of the grinding disc body 1 is flat and smooth and meets the product design standards.

[0029] Falling risk test: Install the assembled grinding disc body 1 on the floor grinder to simulate the actual working conditions. Perform high-speed rotation, frequent start and stop, and grinding force loading tests in different directions. Observe the falling of the grinding disc body 1 during the test. Run continuously for 2 hours. If no falling occurs, it is preliminarily judged to be qualified.

[0030] Grinding performance test: Select a standard floor sample, use the grinding disc body 1 to be tested to perform grinding operations, compare standard grinding parameters, such as grinding depth per unit time, surface flatness and smoothness of the floor after grinding, and other indicators, to determine whether the grinding disc body 1 reaches the designed grinding capacity.

[0031] Durability test: In a simulated high-intensity, long-term use environment, the grinding disc body 1 is repeatedly ground and tested, and the time point when the grinding disc body 1 is worn and damaged is recorded, and compared with the expected service life of the design to ensure that the grinding disc body 1 has sufficient durability;

[0032] Experimental example:

[0033] (I) Hardness test

[0034] The hardness test of the binder part of the grinding disc body 1 was carried out using a Rockwell hardness tester. 10 test points were evenly selected on the surface of the grinding disc body 1, and each test point was 10 mm apart. The test results showed that the average hardness of the binder of the grinding disc body 1 reached HRC60-65, far exceeding the hardness of the traditional metal bond grinding disc body 1, indicating that the wear resistance of the binder has been significantly improved.

[0035] (II) Wear resistance test

[0036] On the abrasive wear tester, a grinding test was conducted on a standard granite test block at a grinding pressure of 1000N and a grinding speed of 30m / s. After 1 hour of continuous grinding, the wear amount of the grinding plate body 1 was measured. The results showed that the wear amount of the new grinding plate body 1 was only 60% of that of the traditional grinding plate body 1, proving that its wear resistance has been greatly improved.

[0037] (III) Self-sharpening test

[0038] The self-sharpening property of the abrasive disc body 1 was evaluated by observing the surface state of the abrasive disc body 1 during the grinding process and measuring the change in the grinding efficiency of the abrasive disc body 1 after different grinding times. The results showed that the grinding efficiency of the new abrasive disc body 1 remained stable throughout the grinding process, the binder could be broken in time to expose new diamond particles, and the self-sharpening property was good.

[0039] (IV) Corrosion resistance test

[0040] The abrasive disc body 1 was placed in an acidic (pH=3 hydrochloric acid solution), an alkaline (pH=10 sodium hydroxide solution) and a humid (humidity 90%) environment, and taken out for observation after 72 hours. The results showed that there was no obvious corrosion on the surface of the abrasive disc body 1, and the binder was firmly bonded to the diamond particles, proving that it has good environmental adaptability.

[0041] In summary, in the present invention, by installing a nylon non-hook reinforced base cloth in the embedding groove 2, the grinding disc body 1 can have good grinding performance while enhancing its own structural strength and toughness, and can withstand greater grinding forces, reducing the risk of damage and breakage of the grinding disc body 1 during use, wherein the mounting groove 4 protrudes 1.5mm on the base 3 and has a width of 1.5mm. This protruding design can provide a better limiting and fixing effect for the grinding disc body 1, effectively preventing the grinding disc body 1 from being displaced and falling off during operation, ensuring that the installation position of the grinding disc body 1 is accurate, and further improving the stability and working accuracy of the grinding disc body 1. The metal sheet arranged in the base 3 and the floor grinder grinding disc magnet generate suction for easy adsorption. In addition, the overall strength and rigidity of the link base 3 can be enhanced, so that it can better support the grinding disc body 1 and adapt to various complex grinding conditions.

[0042] According to actual tests, the service life of the grinding disc body 1 is more than 40% longer than that of the traditional grinding disc under the same grinding conditions. This reduces the replacement frequency of the grinding disc, reduces the processing cost, and improves production efficiency, and is particularly suitable for large-scale, high-intensity processing tasks. The diamond particles of mixed particle size are matched with an optimized binder, so that the grinding disc can not only quickly remove materials during the grinding process, but also ensure the flatness and finish of the processed surface. In the processing of materials such as stone and ceramics, the roughness of the processed surface can be controlled within Ra0.5μm, meeting the requirements of high-precision processing. The addition of molybdenum disulfide lubricating additives reduces friction during the grinding process and reduces energy loss. At the same time, good self-sharpening allows the grinding disc to always maintain efficient grinding capabilities. According to tests, the grinding efficiency of the new grinding disc is about 30% higher than that of the traditional grinding disc, shortening the processing cycle and improving the production efficiency of the enterprise. Due to the reduction of friction during the grinding process and the optimization of the self-sharpening and wear resistance of the grinding disc, the energy required during the processing is reduced. Compared with traditional grinding discs, the new grinding discs reduce energy consumption by about 20% when processing the same material, which is in line with the development trend of energy conservation and emission reduction.
