Problems solved by technology

An endless stream of heat-generating glasses has emerged as the times require. Most of the heat-generating glasses on the market at this stage use transparent conductive films and wires to generate heat to achieve the effect of defogging, deicing, and anti-frost. Although these methods can achieve Requirements, but each has its own defects and limitations: the transparent conductive film has both high conductivity and good light transmittance to visible light, but this transparent film generally contains metal particles or oxide semiconductor particles, This method increases the cost of the conductive film; the wire clamping method has high requirements on the production of heating wire and glass processing technology, and a slight error will easily lead to low transparency of the glass and affect people's visual effects
The comprehensive performance of the products made by this method is generally poor, such as low light transmittance, poor adhesion and other defects

Abstract

The invention mainly aims to provide transparent graphene ink and a preparation method thereof, heating glass using the transparent graphene ink and a preparation method of the heating glass. The transparent graphene ink is prepared from the components in percentage by mass: 10%-40% of a graphene dispersion solution, 40%-60% of a conductive polymer aqueous solution, 5%-10% of a adhesion promoter,1%-5% of a surfactant, and the balance of deionized water; the preparation method includes the steps that the deionized water, the graphene dispersion solution and the conductive polymer aqueous solution are mixed, and ultrasonic dispersion is conducted; the adhesion promoter and the surfactant are added to ultrasonic dispersion, and homogeneous dispersion is conducted to obtain the transparent graphene ink; and the transparent graphene ink is applied on the surface of the a glass substrate and dried; conductive materials are applied on both sides of a graphene ink layer and dried to obtain the heating glass. The transparent graphene ink is high in light transmittance, good in adhesion and low in sheet resistance, when the transparent graphene ink is applied to the glass, the glass can beheated at the low voltage, the anti-fog deicing and snow removal effects are achieved, and thus the transparent graphene ink is more practical.
