Description

Technical Field

[0001] The invention belongs to the field of materials, and in particular relates to a puncture-proof rubber product containing rare earth filler and a preparation method thereof. Background Art

[0002] Rubber products are produced from natural and synthetic rubber as raw materials. Rubber products are widely used in various fields. With the development of science and technology and the needs of production and life, various functional rubber products have been derived, such as puncture-proof rubber products. Such products can be used in many fields, such as medical gloves. In the field of medicine, in addition to tissue diagnosis, dissection and preparation of anatomical pathological specimens are the main tasks of surgical pathologists. Since precision is essential for pathological examination of tissues, the first two activities involve the use of various very sharp blades and scalpels, and suturing corpses in autopsy further implies the use of solid needles. Frequent use of these instruments often leads to injuries, and cuts and needle sutures may range from harmless superficial wounds to deep lacerations. Another danger associated with handling fresh or partially fixed human tissue is the risk of blood-borne diseases. In the 19th century, Austrian-Hungarian physician Ignaz Philipp Semmelweiss first recognized the possibility of disease transmission through autopsy. While many infectious diseases of Semmelweiss's time may not be as deadly today, serious blood-borne diseases such as viral hepatitis B and C (HCV) or human immunodeficiency virus (HIV) remain potentially lethal. The theoretical occupational risk for pathologists and autopsy assistants should never be ignored. In addition, several other infectious diseases have been found to be spread through autopsy or cutting / needle injuries. For this reason, it is crucial to come up with a puncture-resistant rubber product that can be applied to medical gloves, which is also a new topic in the field of medical consumables.

[0012] Furthermore, the rare earth filler is prepared by the following method:

[0013] 1) Evenly mix ferric chlorate, copper chlorate and cerium salt, stir under heating conditions, then add trimesic acid and tetrabutylammonium bromide, and after the reaction is complete, cool to room temperature to obtain a mixture;

[0014] 2) placing the obtained mixture into the inner liner and reacting it in an autoclave, and obtaining an intermediate after the reaction is completed;

[0015] 3) The intermediate is filtered and dried to obtain rare earth filler.

[0016] Furthermore, in step 1), the heating temperature is 70-100° C. and the stirring time is 2-4 hours.

[0017] Preferably, in step 1), the heating temperature is 80° C. and the stirring time is 3 hours.

[0018] Furthermore, in step 2), the material of the lining is polytetrafluoroethylene, the reaction temperature is 150-200° C., and the reaction time is 20-28 hours.

[0022] The present invention also provides a method for preparing the puncture-resistant rubber product containing rare earth filler as described above, the method comprising the following steps:

[0023] 1) Preparation of rare earth fillers

[0024] The ferric chlorate, copper chlorate and cerium salt are mixed uniformly, stirred under heating conditions, and then trimesic acid and tetrabutylammonium bromide are added, and after the reaction is complete, the mixture is cooled to room temperature to obtain a mixture; the obtained mixture is placed in an inner liner, and reacted in an autoclave to obtain an intermediate after the reaction is completed; the obtained intermediate is filtered and dried to obtain a rare earth filler;

[0029] Compared with the prior art, the puncture-resistant rubber product containing rare earth filler and the preparation method thereof of the present invention have the following advantages:

[0030] (1) Rare earth fillers are added to the puncture-resistant rubber product of the present invention. The rare earth fillers are synthesized using chlorates of iron and copper and cerium salts as raw materials. After reacting with organic acids and quaternary ammonium salts, the two metal ions and the rare earth ion cerium form a MOF structure under the action of organic acids. The free chlorate in the chlorate has strong oxidizing properties and can stabilize cerium in a high-valent state, so that there are more sites for cerium ions to combine with organic acids. At the same time, through the action of quaternary ammonium salts, each MOF is linked to form a layered structure, thereby increasing the surface area of ​​the attached gloves, thereby improving the puncture resistance and tensile strength of the gloves.

[0031] (2) The present invention adds rare earth elements, which have a special electronic structure. Using rare earth elements as an intermediate medium in organic matter can block the high-temperature polymerization of some organic matter, making the material have a special microscopic morphology, such as; lamellar, stick-shaped, spherical, etc. The MOF structure formed by the present invention can form a layered structure, and the lamellar structure can be combined with the filler of the gloves to form a stable protective layer, thereby improving the anti-puncture performance of the gloves.

[0032] (3) The puncture-resistant rubber product of the present invention was used to prepare medical gloves. After the MOF sheet was attached to the gloves, the resistance was improved by about 4 times compared with the blank gloves. BRIEF DESCRIPTION OF THE DRAWINGS

[0104] Experimental verification:

[0105] The puncture-resistant rubber products containing rare earth fillers obtained in the above-mentioned embodiments and comparative examples are used to prepare medical gloves:

[0106] The glove model was immersed in the slurry of the puncture-resistant rubber product containing rare earth filler obtained in each embodiment and each comparative example for 3 hours, and then baked and plasticized to obtain a hand mold; then the hand mold was immersed in polyurethane slurry, and finally baked and formed to obtain medical gloves.

[0108] The test instrument is the Labthink Pharmaceutical Packaging Performance Tester i-MEDITEK 1300, and a 6# injection needle is used for puncture. Select the fingertips, palms and other parts of the gloves that are prone to puncture and damage, cut a 1.5×1.5cm sample, and install the sample in the puncture fixture placed on the base of the instrument. Install the injection needle on the upper moving axis of the instrument. Click "Start Test", the instrument starts testing, records the maximum force value during the puncture process, and takes the average of three groups.

[0109] Result analysis:

[0110] 1. Pass Figure 1-Figure 4It can be seen that all kinds of medical gloves doped with rare earth cerium have better puncture resistance than those doped with other rare earth elements. This is due to the diverse forms of cerium atoms (+3 valence and +4 valence), which makes the formed MOF layered structure richer and more stable, making the gloves have strong puncture resistance. In addition, through longitudinal comparison, it was found that CMNO in the nitric acid series has the highest puncture resistance, which is 4.16 times that of the blank group.

[0111] 2. Pass Figure 5 By comparison, it is known that too high or too low metal content will lead to a decrease in the puncture resistance of gloves. Figure 6 By comparison, gloves made of a single metal (copper or iron) are not as puncture-resistant as gloves made of two metals. Figure 7 By comparison, it is known that replacing other acid ions with metal compounds will reduce the puncture resistance of gloves, while gloves prepared with chlorate metals have better puncture resistance. Figure 8 By comparison, it is known that the use of trivalent and divalent cations other than iron and copper ions will lead to a decrease in the puncture resistance of the gloves, while the gloves prepared by using iron ions and copper ions as linking cations of MOF have better puncture resistance. Fig. 9 Comparison shows that compared with ordinary metal MOF structures, gloves with added rare earth elements have better puncture resistance.
