Carbon nanotube reinforced glove and preparation method thereof

Technical Field

The invention relates to the field of gloves, in particular to a carbon nano tube reinforced glove and a preparation method thereof.

Background

The gloves are mainly used for protecting skins from being damaged in daily activities and special environments of people, and can also be used for playing a decorative role in daily life. According to different manufacturing methods, the gloves are divided into knitted gloves, sewn gloves, gum dipping gloves and the like. According to different use functions, the gloves comprise flame-retardant gloves, welding gloves, anti-skidding gloves, oil-resistant gloves, acid and alkali resistant gloves, medical gloves, high temperature resistant gloves, heat-insulating gloves, boxing gloves, working gloves, skiing gloves, guarding gloves, protective gloves, etiquette gloves, space gloves, labor protection gloves and the like. The materials for making the gloves mainly comprise various rubbers, leathers, plastics, fibers and the like.

Common disposable protective gloves in the current market comprise butyronitrile gloves, PVC gloves and latex gloves. The nitrile gloves are NBR in terms of material, a synthetic rubber, and the main components are acrylonitrile and butadiene; the PVC glove is made of polyvinyl chloride; the material of the latex gloves is natural latex (NR). The butyronitrile gloves are degradable, can not be allergic when worn, can be added with pigments, have bright color, and have the defects of poor elasticity and higher price than latex gloves; the PVC gloves have the advantages of low price, capability of adding pigment to mold bright colors and the defect of containing higher plasticizer which is internationally recognized as a healthy public enemy, is heated with volatile harmful gas and can not be degraded; the latex gloves have the advantages of degradability, good elasticity and the like, but skin allergy can be caused when some people wear the latex gloves for a long time.

The Carbon Nanotube (CNT) is a hollow tube rolled by a graphite sheet, has excellent performance due to its unique structure, has an electrical conductivity as high as 1000-2000S/cm, an elastic modulus as high as 1Tpa, a strength 100 times that of steel, and a density of only 1/6 which is rigid. The thermal conductivity of the single-walled carbon nanotube is 6600W/(m.K), the thermal conductivity of the multi-walled carbon nanotube is 3000W/(m.K), and the excellent comprehensive performance leads the CNT to be widely used. CNTs are known as ideal nanofillers because of their excellent electrical and mechanical properties, extremely high thermal conductivity, good thermal stability and chemical properties, high specific surface area, light weight, and the like.

In addition, as a carbon-based material, the carbon nanotube is a nano material with good biocompatibility, so that, in order to solve the technical problems, the glove obtained by compounding the carbon nanotube and the latex has the characteristics of high toughness and enhanced wear resistance, and has the effects of bacteriostasis, allergy resistance and the like.
