Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with specific examples.

[0013] Graphene with a purity of 90% is used as a conductive substance, and water-based polyurethane is used as a binder to equip a water-based paint. Prepare 10 ml of graphene solution with a mass fraction of 0.1% in a 30 ml vial, add 100 mg of sodium dodecylbenzene sulfonate, and ultrasonicate for 60 min to prepare a graphene dispersion. Pour the graphene dispersion into a small beaker, add triton and water-based polyurethane under low-speed mechanical stirring to make the concentration reach 3wt% and 0.5wt%, and obtain the graphene coating. Use a dropper to coat the graphene coating on the glove substrate at a temperature of 130°C, dry it, and carefully immerse it in deionized water for 10 minutes, then take it out and dry it, wash it twice with a large amount of deionized water, and dry it to prepare graphite vinyl conductive gloves.

Abstract

The invention discloses a high-adhesion graphene conductive glove and a preparation process thereof, and is characterized in that (1) the material of the glove is not limited, the graphene conductiveglove can be prepared only by coating the surface of a finished glove with a graphene conductive solution, and the preparation process is simple; (2) waterborne polyurethane, graphene, a dispersing agent and a tackifier are added to prepare the waterborne antistatic coating, so that the waterborne antistatic coating is relatively environment-friendly; (3) a conductive coating is prepared on the surface of the glove through adoption of dropwise adding by a dropper or coating by a scraper; and (4) the waterborne polyurethane increases the adhesive force between the glove substrate and the carbon nanotubes, and the tackifier is used as dye-resistant slurry to prevent the conductive coating from being bloomed in the glove, thereby ensuring that the part which is not coated with the conductivecoating is not bloomed. The graphene conductive gloves are prepared after cleaning and drying.

Description

technical field [0001] The invention relates to a preparation process for simply preparing high-adhesion graphene conductive gloves. Background technique [0002] As smart electronic products enter people's lives, electronic products such as touch-screen mobile phones are widely used. In principle, touch screens are generally divided into two types: capacitive screens and resistive screens. The resistive screen changes the distance between the two screens by pressing, and changes the contact resistance to send instructions. The capacitive screen forms capacitance through the finger and the screen, and sends instructions as the capacitance changes. Compared with resistive screens, capacitive screens are more sensitive, have a longer service life and are not easy to scratch the screen, so capacitive screens are more widely used. Gloves become a must-have item for travel in the cold winter, but because gloves are insulators, the capacitor between the finger and the screen fai...
