Embodiment

[0016] 1. Add the raw material dimethyldichlorosilane of the evaporation source A, adjust the temperature to promote the gasification of the raw material, and carry out the gasification operation of the raw material trichloromethylsilane of the evaporation source B at the same time.

[0017] 2. Adjust the air flow, and adjust the ratio of evaporation source A to evaporation source B to be 1:1.

[0018] 3. During the operation of the conveyor belt, put in the glass to start the coating operation, and adjust the speed of the conveyor belt to 20mm / s.

[0019] 4. The evaporated gas is deposited on the glass surface to form a thin film, and the thin film is tested, and the contact angle and friction resistance are tested.

[0020] Compared with the prior art, the present invention has the advantages that: the present invention adopts the co-deposition method to prepare the hydrophobic film, first of all, it can quickly and efficiently prepare a high-quality hydrophobic film; second...

Abstract

The invention relates to a hydrophobic film. The hydrophobic film comprises a reaction cavity, a first evaporation source and a second evaporation source are arranged at the internal upper end of thereaction cavity, the lower end of the reaction cavity is provided with a gap, a conveyor belt is arranged below the reaction cavity, and the conveyor belt is provided with a glass substrate. The hydrophobic film is prepared by a co-deposition method, so the high-quality hydrophobic film can be quickly and efficiently prepared; the uniformity, the performances and the raw material use amount of thefilm can be precisely controlled; and the hydrophobic film also has the advantages of reduction of the labor cost, low expenditure, reasonable design, and realization of large-scale promotion.

Description

technical field [0001] The invention relates to the field of coating technology, in particular to a hydrophobic film and a preparation method thereof. Background technique [0002] According to the degree of wetting of water on the solid surface (the size of the contact angle), solids can be divided into two categories: hydrophilic and hydrophobic. Among them, the solid surface with a contact angle greater than 150° and a rolling angle less than 10° is usually called superhydrophobic. surface. There are a large number of examples of superhydrophobic surfaces in nature, such as the surfaces of many plant leaves, petals, waterfowl feathers, and insect feet. Because superhydrophobic surfaces have a wide range of application prospects in the fields of waterproof, anti-icing, anti-fog, anti-fouling, anti-corrosion, anti-snow and self-cleaning, they have attracted great attention in both academia and business circles. Based on a large number of in-depth studies on the self-clean...
