Problems solved by technology

Conventional glove materials also have some insufficient strength, resulting in cracks or breakages that cannot be observed by the naked eye, leading to infection
Especially in the case of very dangerous infectious surgery, the cost of this risk is very high

preparation example Construction

[0034]The preparation methods of modified graphene or graphene derivatives include but are not limited to the following three methods: 1. graphene powder or liquid phase dispersion prepared by expansion and exfoliation of graphite as raw material and subsequent modified products (fluorination, Carboxylation, sulfoylation, amination, oxidation, grafting and other modified derivatives); ② Graphene prepared by chemical vapor deposition (CVD) or physical vapor deposition (PVD) using gaseous carbon source as raw material and its subsequent modification (fluorination, carboxylation, sulfonation, amination, oxidation, grafting and other modified derivatives); ③The powder or liquid phase formed by the aggregation of graphene-like two-dimensional sheet materials formed by chemical polymerization of small molecules Dispersion and its subsequent modification (fluorination, carboxylation, sulfonation, amination, oxidation, grafting and other modification and derivation).

Embodiment 1

[0038] According to the composite process described above, the modified graphene / natural latex composite medical gloves (category 1) were prepared according to the conventional process. According to the dry weight ratio after drying, the mass content of graphene after drying in category 1 was 0.5‰. Modified graphene / nitrile latex composite medical gloves (category 2), calculated according to the dry weight ratio after drying, the mass content of graphene after final drying of category 2 is 1.0‰.

[0039] The specific process is as follows:

[0040] Mold cleaning (hot water spraying and brushing), soaking in coagulant and drying (drying at 80-90°C), soaking in vulcanized latex, leaching or drying (hot water or hot air at 60-80°C), coloring, curling , film drying (90~110 ℃), immerse release agent powder liquid (20~30% calcium carbonate and talcum powder suspension, by weight ratio, soak the calcium carbonate in the release agent powder liquid: talcum powder=1: 1, the rest is wa...

Abstract

The invention relates to the fields of composite material and medical instruments, and specifically, relates to a method for preparing high-strength and high-isolation medical gloves by using a modified graphene / latex composite material. Modified graphene is made into a stable dispersion liquid, then direct compositing is carried out after a latex cooperation and presulfurization curing stage, or sulfurization and compositing are completed at the same time in the stage, and finally, the composite latex is prepared. After the composite latex is cured, the medical gloves products are prepared by a mould immersion method. Compared with conventional products, the prepared graphene composite medical gloves effectively block small-size viruses from penetrating, and satisfy the characteristics of high security and superior aging resistance. The method has the advantages of scientific principle, significant characteristics, no toxicity, no harm, stable performance, and high matching degree with a production process of the conventional medical gloves and the like.

Description

technical field [0001] The invention relates to the field of composite materials and medical devices, in particular to a method for preparing high-strength and high-insulation medical gloves using modified graphene / latex composite materials. Background technique [0002] Medical latex gloves are not only necessary medical supplies for doctors, but also a standing item for family life. It has good hygienic barrier properties and excellent film strength. The research report shows that the film of medical gloves can effectively shield the pathogens of diseases such as venereal diseases and AIDS. The high elasticity of latex gloves gives it better grip performance and shape compliance. This characteristic cannot be replaced by any other material. It is also the main reason why medical latex gloves are still used as surgical medical supplies at home and abroad. [0003] Proper use of medical gloves can significantly reduce the chance of bacterial infection. The materials curre...
