Problems solved by technology

However, this type of silicate laminated glass has a high light transmittance, especially in the summer high temperature period, when high-intensity visible light passes through the laminated glass of the front windshield of the car, which not only hinders the driver's sight, causes visual fatigue, causes dizziness, and increases the Driving risk. Moreover, strong infrared heat radiation will also increase the temperature inside the car and increase the power load brought by the car air conditioner, which is not conducive to the sustainable development of cars in the direction of energy saving and environmental protection.

Abstract

The invention relates to the technical field of hydrophilic glass and in particular relates to a super-hydrophilic agent. The super-hydrophilic agent is characterized by being composed of the following components in percentage by weight: 0.1-0.45% of ZnO nanorod, 1.5-5% of carbon nano tube powder, 12-18% of N,N-dimethylformamide and the balance of dispersion, wherein the carbon nano tube powder is single-walled or multi-walled carbon nano tube powder; and the carbon nano tubes are attached to the surface of the ZnO nanorod. The invention further provides a preparation method of the super-hydrophilic agent and super-hydrophilic window glass provided with a super-hydrophilic coating. The super-hydrophilic agent disclosed by the invention has the advantages that the super-hydrophilic agent is high in visible light transmittance and capable of absorbing infrared and ultraviolet radiation and has excellent super-hydrophilic characteristics under non-illumination conditions.

Description

Technical field: [0001] The invention relates to the technical field of hydrophilic glass, in particular to a superhydrophilic agent, a preparation method of the superhydrophilic agent and a superhydrophilic vehicle window glass provided with a superhydrophilic coating. Background technique: [0002] The wettability of material surfaces has always been the focus of academic and industrial circles. Superhydrophilic and superhydrophobic, as two extremely special wetting phenomena, have attracted extensive research by domestic and foreign scholars in recent years. In general, a superhydrophobic surface refers to a surface with a solid-liquid contact angle greater than 150°. Conversely, a superhydrophilic surface is one in which liquids can spread completely, resulting in a contact angle equal to or close to 0°. Compared with superhydrophobic research, there are fewer studies on superhydrophilicity, but due to the unique wetting characteristics of superhydrophilic surfaces, sup...
