Problems solved by technology

Therefore, it is inevitable that the color instability will inevitably occur in gloves made of graphene composite latex, which will affect the use perception and performance weather resistance. The more graphene is added, the grayer and darker the latex will be. [2]

Embodiment 1

[0033] In this example, the method for preparing high-strength, non-allergic, and high-isolation medical gloves by laminating graphene with hexagonal nanosheet boron nitride composite latex is as follows:

[0034] Preparation of graphene / hexagonal nanosheet boron nitride bonded body solution: 1kg of graphene oxide aqueous solution with a concentration of 2wt‰ is negatively charged after being charged by an electric field. 1 kg of an aqueous solution containing 0.1wt‰ hexagonal boron nitride nanosheet material was modified with 0.1wt‰ polyvinylpyrrolidone. Then the two are mixed and stirred ultrasonically to make them dispersed evenly. Adding 10Kg concentration then is the natural rubber latex of 60wt% in the clean mixing tank, under agitation condition, add gradually the graphene / hexagonal nanosheet boron nitride bonding body solution of 2.1wt‰ that the 2Kg concentration that prepares in front, After the addition is complete, add 0.1wt‰ dispersion stabilizer Pingpinga O (alky...

Abstract

The invention relates to the fields of composite materials and medical instruments, in particular to a method for making a high-strength non-allergenic highly-isolated medical glove by fitting graphene with hexagonal nanometer lamellar boron nitride composite latex. The method comprises the following steps: compounding graphene subjected to electric field treatment with modified hexagonal nanometer lamellar boron nitride in a fitting way to form a stable dispersion, wherein the pH of the dispersion is 4.5 to 7; then, dispersing the dispersion into latex, and compounding according to the solid mass proportion of 0.1 to 10 percent by weight to finally make the medical glove. Compared with the conventional graphene glove, the glove made by the method has the advantage that the defects of poor weather resistance stability, and greying and darkening caused by deterioration of the graphene are overcome. After the graphene is compounded with nanometer less-layer boron nitride which is named 'white graphene', the tensile strength, toughness and heat conductivity of the medical latex glove can be enhanced, and the permeation of virus liquid can be effectively blocked. The method has the characteristics of scientific principle, inertia, nontoxicity and good weather resistance, and can be used for making thermal-stable, high-conductivity and highly-isolated gloves.

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, non-sensitizing, and high-insulation medical gloves by laminating graphene with hexagonal nanosheet boron nitride composite latex. 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 higher elasticity of latex gloves gives it better grip performance and form conformity performance. This characteristic cannot be replaced by any other material, and 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 significantl...
