Abstract

The invention relates to scratch-resistant hydrophobic glass and a preparation method thereof. The scratch-resistant hydrophobic glass comprises a glass substrate (1), and is characterized in that a sintering layer (2) and a hydrophobic film (3) are arranged on the glass substrate (1). The preparation method comprises the following steps: a, preparing an SiO2 first aggregate; b, preparing an SiO2second aggregate dispersing agent; c, adding the SiO2 first aggregate into the SiO2 second aggregate dispersing agent, adding a silane coupling agent, and stirring to obtain an SiO2 mixed dispersing agent; d, smearing the SiO2 mixed dispersing agent on the surface of the glass substrate; e, heating the glass substrate to form the sintering layer; and f, smearing a low surface energy material on the sintering layer for solidification. The scratch-resistant hydrophobic glass has the advantages that firstly, the prepared sintering layer is stable in structure and unlikely to be separated, and lasting protection can be realized; secondly, through the synergistic effect of the SiO2 first aggregate and second aggregate, the stress is reduced through the hydrophobic film, the abrasion is reduced,the adhesive force is improved, the deformation and movement of the film are blocked, and the separation of the hydrophobic film from the surface of the glass and the destroy of a coarse structure are blocked effectively; and thirdly, the hydrophobic glass has relatively high visible light transmittance.

Description

technical field [0001] The invention belongs to the technical field of glass production, relates to the technical field of glass surface modification, in particular to a scratch-resistant hydrophobic glass and a preparation method thereof. Background technique [0002] The glass surface is hydrophilic, and the adhesion of water droplets on the glass surface will seriously affect the perspective of the glass. At present, the method of coating the glass surface with a hydrophobic film is used to solve the above problems. The hydrophobic film is a kind of low surface energy material. Water-like materials and water repel each other. When water forms a large contact angle (greater than 90°) on the surface of hydrophobic materials, it is easy to roll off. Combining low-energy surface energy materials with an appropriate rough structure on the glass surface can further Improve hydrophobic properties. [0003] However, the hydrophobic properties of artificially manufactured hydroph...
