Abstract
Description

[0002] In the fields of medicine, scientific research, new energy, military industry, etc., some special material processing and storage processes require operations in relatively clean and confined spaces. Especially when handling toxic and hazardous chemicals, the protective materials used by operators must have extremely high performance requirements to ensure the safety of operation and the reliability of protection. The special working environment in these fields places strict requirements on protective gloves: in addition to excellent flexibility and comfort, protective gloves must also have air tightness, chemical resistance, aging resistance, radiation resistance, puncture resistance, wear resistance and other properties to effectively ensure the safety of operators when performing tasks. However, the protective glove materials on the existing market have significant deficiencies in meeting the above performance requirements. Although some traditional materials such as natural rubber gloves have certain chemical resistance and durability, they still face problems such as pressure resistance, holes, swelling deformation, and cracking during long-term use, especially when used under high-intensity chemical reactions, radiation or extreme working conditions, the protective performance cannot be maintained continuously. These problems make the existing materials unable to effectively respond to the use needs in high-risk environments, and they need to be replaced frequently, which increases the cost of use and reduces work efficiency.
[0003] Chlorosulfonated polyethylene (CSM) is a high-performance special rubber material with excellent chemical resistance, ozone oxidation resistance, oil corrosion resistance, flame retardancy and aging resistance. Therefore, it is widely used in wires and cables, liquid seals and protective gloves. Its molecular structure contains chlorosulfonyl groups, which give it high activity and excellent mechanical properties. Especially in the fields of medicine, scientific research, new energy and military industry, chlorosulfonated polyethylene gloves have become ideal protective tools in specific environments due to their excellent flexibility, air tightness, chemical resistance, radiation resistance, aging resistance, puncture resistance and wear resistance. At present, the main methods for preparing chlorosulfonated polyethylene gloves include dipping, coating and molding. Among them, the dipping method has become the most commonly used preparation method due to its simple process, low equipment investment and stable product quality. The main problems in the preparation of chlorosulfonated polyethylene gloves in the prior art are as follows: 1. The formula composition of the existing chlorosulfonated polyethylene gloves is relatively simple, which is difficult to meet multiple protection needs; 2. In the traditional dipping process, it is difficult to control the viscosity of the chlorosulfonated polyethylene slurry, which affects the uniformity of the product; 3. The chemical resistance of the existing chlorosulfonated polyethylene gloves is not comprehensive enough, and the protection effect on certain special media is poor; the product has a short service life and is prone to aging, cracking and other problems after long-term use.

[0035] The chlorosulfonated polyethylene gloves prepared in Example 3 were subjected to performance tests, and the specific test results are shown in Table 3.
[0036] Table 3
[0037] Example 4 In this embodiment, the material adopts three functional layers, namely, an air-liquid isolation layer, an aging enhancement layer and an anti-radiation layer. It is formed through a multi-layer impregnation process. The thickness of a single layer is 0.05-0.06mm, the thickness of the air-liquid isolation layer is 0.2-0.3mm, the thickness of the aging enhancement layer is 0.2-0.3mm, and the thickness of the anti-radiation layer is 0.1-0.2mm; the innermost layer is the air-liquid isolation layer, the anti-radiation layer is on the outer layer of the air-liquid isolation layer, and the aging enhancement layer is on the outer layer of the anti-radiation layer.

[0039] The chlorosulfonated polyethylene gloves prepared in Example 4 were subjected to performance tests. The specific test results are shown in Table 4.
[0040] Table 4
[0041] Based on Examples 1-4, further, in step c, when the mold is immersed downwardly into the liquid slurry raw material by a vertical device and completely submerged therein, an intelligent control system is used to regulate the dipping process of the vertical device, including: Conduct fluidity analysis on the liquid mortar raw materials to obtain data information on the fluidity of the liquid mortar raw materials; Acquire mold attribute information, and analyze the mold surface adhesion performance in combination with the fluidity data of the liquid glue raw material to obtain mold surface adhesion analysis data; Determine the target thickness of the functional layer; The target thickness of the functional layer is combined with the mold surface adhesion analysis data to perform an impregnation rate analysis to determine the target impregnation rate; Perform impregnation simulation according to the target impregnation rate to obtain impregnation simulation data; Performing idealized analysis based on the impregnation simulation data to determine the difference between the impregnation simulation data and the idealized data, and judging whether the target impregnation rate needs to be adjusted based on the difference between the impregnation simulation data and the idealized data to obtain a simulation analysis result; When the simulation analysis result shows that the target dipping rate does not need to be adjusted, the mold is positioned above the corresponding liquid mortar raw material by a horizontal device, and then the mold is dipped at a first rate. When the mold contacts the liquid mortar raw material, the first rate is adjusted to the target dipping rate and the dipping is continued until the mold is submerged in the liquid mortar raw material. When the simulation analysis results show that the target impregnation rate needs to be adjusted, the target impregnation rate is adjusted according to the difference between the impregnation simulation data and the idealized data to obtain the target impregnation correction rate. Then, the mold is positioned above the corresponding liquid glue raw material through a horizontal device and immersed at a first rate. When the mold contacts the liquid glue raw material, the first rate is adjusted to the target impregnation correction rate and then the immersion is continued until the mold is submerged in the liquid glue raw material.
[0042] The target thickness is negatively correlated with the impregnation rate. The thicker the target thickness is, the smaller the impregnation rate is. The mold surface adhesion is positively correlated with the impregnation rate. The greater the mold surface adhesion is, the greater the impregnation rate is. The first rate is greater than the target impregnation rate or the target impregnation correction rate.
[0043] The above-mentioned analysis of the adhesion performance of the mold surface by combining the fluidity data information of the liquid mortar raw materials makes it clear that different liquid mortar raw materials are compatible with the mold, so that when different liquid mortar raw materials form corresponding functional layers on the mold surface, the target thickness can be better obtained, the impregnation effect can be improved, and the accuracy of obtaining the functional layer can be guaranteed. Moreover, after obtaining the target impregnation rate, the impregnation simulation is performed according to the target impregnation rate, the impregnation effect of the target impregnation rate is pre-defined, the impregnation error of the target impregnation rate is reduced, the accuracy of obtaining the functional layer is improved, the effect of the functional layer is ensured, and the quality assurance of the chlorosulfonated polyethylene gloves is improved. And when the mold contacts the liquid mortar raw material, by adjusting the first rate to the target impregnation rate, the intelligent adjustment of the immersion is realized, which can not only improve the efficiency of the immersion, but also ensure the acquisition of the functional layer.
[0044] Furthermore, in step d, after the liquid glue raw material adhered to the mold surface is solidified to form the corresponding functional layer, the corresponding functional layer formed is also tested, including: acquiring functional layer data information for the corresponding functional layer formed; analyzing whether the functional layer is evenly distributed according to the functional layer data information to obtain a first analysis result; when the first analysis result is that the functional layer is evenly distributed, performing a thickness analysis and judgment on the functional layer to determine whether the thickness of the functional layer meets the target thickness to obtain a second analysis result; when the second analysis result is that the thickness of the functional layer does not meet the target thickness, analyzing and calculating the relationship between the thickness of the functional layer and the target thickness; if the thickness of the functional layer is less than the target thickness, obtaining the difference between the thickness of the functional layer and the target thickness, and performing a secondary impregnation of the functional layer according to the difference between the thickness of the functional layer and the target thickness; if the thickness of the functional layer is greater than the target thickness, giving a thickness exceeding standard reminder to the functional layer. When the first analysis result is that the functional layer is unevenly distributed, the functional layer is divided into regions according to its distribution, the thickness of the functional layer region is obtained, and the thickness of the functional layer region is analyzed to determine whether the thickness of the functional layer region meets the target thickness, and a third analysis result is obtained. If the third analysis result is that the thickness of the functional layer region meets the target thickness, there is no need to perform local area impregnation correction on the functional layer. If the third analysis result is that the thickness of the functional layer region does not meet the target thickness, the functional layer region that does not meet the target thickness is screened out to determine the abnormal functional layer region, and then it is analyzed and determined whether the abnormal functional layer region can be impregnated to obtain a fourth analysis result. When the fourth analysis result is that the abnormal functional layer region can be impregnated, an impregnation correction analysis is performed on the abnormal functional layer region to determine the impregnation correction information, and then the abnormal functional layer region is impregnated according to the impregnation correction information. When the fourth analysis result is that the abnormal functional layer region cannot be impregnated, a non-compliance reminder is given to the functional layer.
[0045] By testing the corresponding functional layer formed, it is ensured that the corresponding functional layer formed by curing meets the requirements, so that the functional layer has better functional effects, provides guarantees for the specific functions of the chlorosulfonated polyethylene gloves, improves the functional effects of the chlorosulfonated polyethylene gloves, and provides guarantees for the quality of the chlorosulfonated polyethylene gloves.
[0046] The present invention achieves a comprehensive improvement in the performance of gloves by designing a composite glove with a multifunctional structural layer and adopting a specific combination of an air-liquid isolation layer, an aging reinforcement layer, and an anti-radiation layer. By adding a specific proportion of epoxy resin, magnesium oxide, silicon dioxide and other components to chlorosulfonated polyethylene rubber, the air tightness and chemical resistance of the gloves are significantly improved. After testing, the immersion time of the gloves in strong corrosive media such as 96% sulfuric acid and 40% sodium hydroxide can reach 480 minutes. The combination of polyols and specific antioxidants introduced into the aging reinforcement layer makes the gloves retain more than 97% of the tensile strength and elongation at break after aging in hot air at 125°C for 72 hours, and no cracking occurs after aging for 72 hours at an ozone concentration of 200ppm, reflecting excellent aging resistance. The anti-radiation layer can play a good shielding role against radiation by adding bismuth powder and tungsten powder. The preparation method based on the impregnation process, through the precise control of the mold type, the number of impregnations and the curing conditions, makes the product have excellent dimensional stability, and the uniformity deviation of the glove wall thickness is controlled within ±0.02mm, which significantly improves the consistency of product quality. The improvement of the overall performance of the product has expanded the application range of CSM gloves. They are particularly suitable for fields such as medicine, nuclear industry, precision electronics, etc. that have strict requirements on protective performance, and have important practical value.
[0047] Finally, it should be noted that the above-mentioned embodiments only express several implementation methods of the present invention and are not intended to limit the invention. For those skilled in the art, any modification, equivalent replacement, improvement, etc. made without departing from the concept of the present invention should be included in the protection scope of the invention.
