[0097] The other steps are the same as those in Example 1, and finally the puncture-resistant rubber product rubber skin XJ13 is manufactured.

[0098] Experiment: Comparison of puncture resistance

[0099] The puncture resistance performance of puncture-resistant rubber materials is its core evaluation index.

[0100] At present, the puncture resistance performance test methods for puncture-resistant rubber materials mainly include mechanical puncture tests and puncture tests simulating actual working environments. Through these test methods, the puncture resistance performance of puncture-resistant rubber materials can be comprehensively evaluated, providing a scientific basis for their application in different fields.

[0101] The specific detection method is: first, the rubber made of ordinary rubber material without rare earth filler (control group) and the rubber made of puncture-resistant rubber material with rare earth filler (experimental group) are cut or prepared according to the specified size and shape to ensure the integrity and consistency of the samples. At the same time, the samples are properly cleaned and treated to eliminate the influence of surface contamination and impurities on the test results. According to the test standards and sample characteristics, puncture test equipment with high precision and stability is selected to ensure that the parameters of the equipment are set correctly, such as puncture speed, force, etc., to meet the test requirements. Then install the fixture correctly according to the equipment manual to ensure that it is stable and reliable. Place the processed sample in the fixture, and adjust the position and angle of the fixture so that the sample is in the correct position and state during the test. After confirming that the sample is clamped and positioned correctly, start the puncture test. According to the requirements of the test standard, control the puncture speed, force and other parameters, set up 3 parallel groups for each experimental group, and finally record the average test results. The experimental results are as follows Figure 3 , Figure 4 As shown:

[0102] We first tested the blank control rubber without rare earth additives. After setting up three parallel groups and taking the average, we found that the thickness of the blank control rubber was 0.126mm and the puncture force was 2.14N.

[0103] Thickness, such as Figure 3 As shown in the figure, after adding different rare earth fillers LaFCS, the thickness of the rubber changed differently. First, the thickness of XJ1-3 increased by less than 0.01mm, and the thickness change was not large. However, XJ4-13 increased by about 0.03. This is because the synthesis process of XJ4-13 is incorrect, resulting in an imperfect sheet structure of the material, so the thickness of the rubber will be greatly affected when added in the process, especially XJ8. The rare earth material has not been washed, resulting in more impurities, and the thickness of the rubber produced in the end increased significantly.

[0104] In terms of puncture force, Figure 4 As shown in the figure, the puncture resistance of XJ1-3 is significantly improved, more than 2 times that of the blank control. The puncture resistance of XJ4-13 is also improved, but the improvement effect is worse than that of XJ1-3. On the one hand, it is due to the addition of rare earth materials as additives. After all, there is one more ingredient, which will increase some puncture resistance. On the other hand, the increase in the thickness of the rubber will also bring some puncture resistance. However, considering all factors, XJ1-3 still has the best puncture resistance. It does not change the thickness of the rubber, maintains the sensitivity of the rubber, and increases the puncture resistance of the rubber. In practical applications, it can improve the protection effect of operators.

[0105] In addition, through the comparison of the above comparative examples, it can be seen that the puncture resistance of the puncture-resistant rubber material is related to the composition and proportion of the rare earth filler, and is also related to the preparation conditions of the rare earth material LaFCS. Only by preparing the rare earth material LaFCS according to the scheme given in this application can the puncture resistance of the rubber material be better improved.

[0106] In summary, the rare earth filler LaFCS material is non-toxic and healthy, and the preparation process is green and environmentally friendly. Adding rare earth filler LaFCS in the rubber production process can improve the rubber's anti-puncture ability. With the continuous optimization of preparation technology and filling methods, the performance of puncture-resistant rubber will continue to improve and will be able to meet the needs of more fields.

[0107] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
