Description
Technical Field
The invention relates to the technical field of nitrile gloves, in particular to a nitrile latex composition, a nitrile glove and a preparation method and application thereof.
Background
The disposable rubber glove is widely applied to the fields of medical examination, health protection, food industry and the like, and has the characteristics of convenient use, disposability and the like. According to the materials, the glove for medical use can be further divided into latex glove using natural rubber latex as main raw material, nitrile glove using nitrile rubber latex as main raw material, PVC glove using polyvinyl chloride paste resin and plasticizer as main raw material, etc. The PVC glove has the advantages of low price, hard hand feeling, low elongation, low plasticizer content, easy dissolution of organic solvent components, poor protective performance, proper price, far superior oil resistance and solvent resistance to latex glove and PVC glove, wide application, low elongation of the nitrile glove and durability. The physical properties of standard ASTM for these three materials of medical examination gloves are shown in table 1, wherein after aging it is after accelerated aging for 168 hours at 70 ℃ as specified in the standard.
TABLE 1 Standard ASTM D412
| Physical property requirements of gloves | Natural latex glove | Butyronitrile glove | PVC gloves |
| Strength before aging (MPa) | 18 | 14 | 7.5 |
| Elongation before aging (%) | 650 | 500 | 300 |
| Post aging strength (MPa) | 14 | 14 | 7.5 |
| Elongation after aging (%) | 500 | 400 | 300 |
| Product requirement-U.S. Standard number | ASTM D3578 | ASTM D6319 | ASTM D5250 |
The stretching stress of the natural latex glove is lower than that of the conventional nitrile glove and PVC glove, and the glove has softer hand feeling, for example, the 300% stretching stress of the natural latex glove is only 1Mpa to 4Mpa, but the 300% stretching stress of the conventional nitrile glove reaches 6Mpa to 15Mpa, and the 300% stretching stress of the PVC glove is more than 7 Mpa. Meanwhile, the performance of the natural latex glove and the nitrile glove can be reduced after aging, particularly the elongation rate can be obviously reduced, so that the performance of the glove is reduced, and the elongation rate and the softness are reduced after the glove is transported for a long distance or stored and placed.
In addition, the existing nitrile glove has the problem of intolerance to wear, especially when the glove has high elongation, such as the glove with the elongation of 600 percent, and the glove is damaged when being continuously worn for basically no more than 60 minutes. Many gloves, when worn continuously and used normally for more than 90 minutes, will have cracks and holes, especially at the root of the thumb and places where the finger is more stressed during daily use. Not only does the need for frequent glove replacement by the user increase cost in an intangible way, but also the potential risk of losing protection is created due to the occurrence of minor breakage in use that is not readily noticeable.
Accordingly, there is a need to develop a nitrile latex composition that enables gloves to be compatible with elongation, tensile stress and durability properties for use in medical gloves.

(1) The properties associated with the nitrile gloves were measured using the nitrile latex compositions of examples 1-10 and comparative examples 1-6, respectively, using the Standard ASTM-D412 vulcanized rubber and thermoplastic elastomer tensile test method, wherein after aging the nitrile glove was accelerated at 70℃for 168 hours as specified in the Standard.
(2) The durability detection method is as follows:
10 workers at the same post were randomly located from the company's production facility, 5 men and 5 women. Before wearing gloves, firstly performing inflation inspection on the gloves to ensure that the gloves have no visual loopholes and areas with parts which are obviously thinner, then arranging that each worker wears the gloves on both hands, performing daily work, wherein the work content of 10 workers is the same, visually inspecting the gloves worn on the hands of the workers every 5 minutes to see whether the gloves are broken such as cracks and holes, stopping wearing and recording the puncturing time if the gloves are broken, and ending the test if the gloves are still unbroken after two hours. The inspector records the breakthrough time of all the gloves, and the median value of the breakthrough time of all the gloves is taken as a result. The longer the time to puncture, the more durable the glove.
The test results are shown in Table 3.
