[0024] Unless otherwise stated, the term "plurality" means two or more.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0026] like Figure 1 As shown, an embodiment of the present disclosure provides a method for manufacturing a plastic wear-resistant plate repair material, comprising: Step S1: mixing a preset mass fraction of a vinyl resin and a curing agent and stirring to form a first prefabricated mixture; Step S2: adding a preset mass fraction of an accelerator to the first prefabricated mixture and stirring the mixture to form a second prefabricated mixture; Step S3: adding a preset mass fraction of graphite powder into the second prefabricated mixture and stirring until the mixture is uniform to obtain the desired repair material.

[0027] Specifically, the method for making the plastic wear-resistant plate repair material used in the present invention can be used for corrosion-resistant and wear-resistant circulating pumps. According to the preset mass ratio, the vinyl resin, curing agent, accelerator and graphite powder are fully mixed and uniform. Among them, the vinyl resin and the curing agent are first mixed, wherein the vinyl resin is first placed in a plastic bucket, and then the curing agent is placed. Stirring is performed during the mixing process, but the stirring time should not be too long or too short. If the stirring time is too long, the mixed liquid will solidify, and if the stirring time is too short, it cannot be mixed uniformly. Therefore, the general stirring time is preferably 5-10 minutes. Only after the vinyl resin and the curing agent are mixed, the accelerator can be added for mixing and stirring. The stirring time is also preferably 5-10 minutes. It should be noted that the curing agent and the accelerator cannot be added at the same time, and should be strictly followed in the manner of curing agent first and then accelerator. Finally, after adding the graphite powder, stir until uniform to obtain the repair material.

[0028] In the preferred technical solution of the present application, the usage amount of the curing agent and the accelerator gradually decreases as the temperature increases.

[0029] Specifically, the curing agent and the accelerator not only have a sequence of addition, but their mass ratio in the entire mixture is also related to the temperature. The lower the temperature, the greater the mass ratio of the curing agent and the accelerator is required.

[0030] In the preferred technical solution of the present application, at a temperature of 40°C, the mass ratio of vinyl resin, curing agent, accelerator and graphite powder in the repair material is: 65:9:6:20.

[0031] Specifically, through a large number of experiments, the use temperature of this repair material should be maintained at 25℃~40℃. If the temperature is too low, the curing time is long; if the temperature is too high, the curing is too fast, which is not conducive to repair. Among them, the optimal mass ratio of vinyl resin, curing agent, accelerator and graphite powder at a temperature of 40℃ is 65:9:6:20. And in the mixing reaction process, it is still necessary to mix the vinyl resin and curing agent first, then add the accelerator, and then add the graphite powder after the mixing is evenly mixed, and mix them evenly.

[0032] In the preferred technical solution of the present application, at a temperature of 30°C, the mass ratio of vinyl resin, curing agent, accelerator and graphite powder in the repair material is 60:13:10:17.

[0033] Specifically, similar to the situation at 40°C, the optimal mass ratio of vinyl resin, curing agent, accelerator and graphite powder at 30°C is 60:13:10:17. In the mixing reaction process, the vinyl resin and curing agent are mixed first, and then the accelerator is added. After the mixing is uniform, the graphite powder is added and mixed uniformly.

[0034] In the preferred technical solution of the present application, at a temperature of 25°C, the mass ratio of the vinyl resin, the curing agent, the accelerator and the graphite powder in the repair material is 56:17:13:14.

[0035] Specifically, similar to the situation at 30°C, the optimal mass ratio of vinyl resin, curing agent, accelerator and graphite powder at 25°C is 56:17:13:14. And in the mixing reaction process, it is still necessary to mix the vinyl resin and curing agent first, then add the accelerator and add the graphite powder after the mixture is evenly mixed. Comparison of the three situations at 40°C, 30°C and 25°C also confirms that the amount of curing agent and accelerator used gradually decreases as the temperature increases.

[0036] In the preferred technical solution of the present application, during the process of making the repair material, a pistol drill is used for stirring, and the stirring time ranges from 5 minutes to 10 minutes.

[0037] Specifically, the stirring power of the pistol drill is sufficient. If the stirring time is too long, the mixed liquid will solidify, and if the stirring time is too short, it will not be mixed evenly. Through a large number of experiments, it is found that the stirring effect is best when the stirring time is within 5-10 minutes.

[0038] In the preferred technical solution of the present application, the curing agent is 388 curing agent and the accelerator is 1305 accelerator.

[0039] Specifically, 388 curing agent and 1305 accelerator are commonly used curing agents and accelerators. Other curing agents and accelerators are also acceptable as long as they can achieve similar technical effects.

[0040] like Figure 2 As shown, in the second aspect of the present invention, a repair method using the aforementioned plastic wear-resistant plate repair material for repair comprises the following steps: S4: Clean the part of the device to be repaired and place it in a dust-free environment; S5: Apply the repair material evenly to the area to be repaired and leave it for a preset time to cure.

[0041] Specifically, the repaired part of the wear-resistant plate should be cleaned, and oil, water and dust are strictly prohibited. After cleaning, apply the prepared repair liquid evenly to the damaged part with a brush to achieve repair.

[0042] In the preferred technical solution of the present application, the preset standing time is 30 minutes to 40 minutes, and during the standing process, heat is generated by self-reaction to perform heating and curing.

[0043] Specifically, after filling the damaged part, the material is allowed to stand for 30 to 40 minutes to cure, and then the repair can be achieved. The matrix of the present invention does not need to be heated, and the material generates heat through reaction to automatically heat and cure.

[0044] In the preferred technical solution of the present application, the repair personnel need to wear protective equipment during the entire repair process.

[0045] Specifically, protective equipment such as masks, goggles, and plastic gloves should be worn during preparation and use.

[0046] Example 1, first weigh the vinyl resin, 388 curing agent, 1305 accelerator and graphite powder according to the mass ratio of 65:9:6:20. Subsequently, the vinyl resin is placed in a plastic bucket and then the 388 curing agent is also placed in the plastic bucket, and a uniform first prefabricated mixture is obtained by stirring with a pistol drill for 8 minutes. Then the 1305 accelerator is added and stirred with a pistol drill for 8 minutes to obtain a uniform second prefabricated mixture. Finally, graphite powder is added to the second prefabricated mixture, and stirred with a pistol drill for 8 minutes to obtain the final required repair material. The required repair material is kept at a constant temperature of 40 degrees. Clean the part to be repaired of the device to be repaired to ensure that there is no oil, water, or dust. Then the repair material is evenly applied to the damaged part to be repaired and kept at a constant temperature of 40 degrees for half an hour to achieve a good curing effect.

[0047] Figure 3 The plastic wear-resistant plate with holes and grooves damaged by material scouring is shown in FIG. 1 and can no longer be used normally and can only be scrapped. Figure 4 As shown, the repaired plugging wear-resistant plate has good corrosion resistance and wear resistance. Its performance meets the requirements of on-site use and can be used normally on the machine, effectively extending its service life.

[0048] Example 2, first weigh the vinyl resin, 388 curing agent, 1305 accelerator and graphite powder according to the mass ratio of 56:17:13:14. Subsequently, the vinyl resin is placed in a plastic bucket and then the 388 curing agent is also placed in the plastic bucket, and a uniform first prefabricated mixture is obtained by stirring with a pistol drill for 10 minutes. Then the 1305 accelerator is added and stirred with a pistol drill for 10 minutes to obtain a uniform second prefabricated mixture. Finally, graphite powder is added to the second prefabricated mixture, and stirred with a pistol drill for 10 minutes to obtain the final required repair material. The required repair material is kept at a constant temperature of 25 degrees. Clean the part to be repaired of the device to be repaired to ensure that there is no oil, water, or dust. Then the repair material is evenly applied to the damaged part to be repaired and kept at a constant temperature of 25 degrees for half an hour to achieve a good curing effect.

[0049] Example 3, first weigh the vinyl resin, 388 curing agent, 1305 accelerator and graphite powder according to the mass ratio of 60:13:10:17. Subsequently, the vinyl resin is placed in a plastic bucket and then the 388 curing agent is also placed in the plastic bucket, and a uniform first prefabricated mixture is obtained by stirring with a pistol drill for 6 minutes. Then the 1305 accelerator is added and stirred with a pistol drill for 6 minutes to obtain a uniform second prefabricated mixture. Finally, graphite powder is added to the second prefabricated mixture, and stirred with a pistol drill for 6 minutes to obtain the final required repair material. The required repair material is kept at a constant temperature of 30 degrees. Clean the part to be repaired of the device to be repaired to ensure that there is no oil, water, or dust. Then apply the repair material evenly to the damaged part to be repaired and keep it at a constant temperature of 30 degrees for half an hour to achieve a good curing effect.
