Problems solved by technology

[0005] The technical problem mainly solved by the present invention is to provide a method for preparing a hydrophobic glass film for automobiles, aiming at the drawbacks such as affecting the driver's line of sight during the use of the car wiper in rainy days and leaving traces of uneven wiping on the glass surface. The mixed solid and polyethylene terephthalate resin obtained from leaf and flax fiber are used to prepare film, and the surface is treated with corona to make the film hydrophobic. The film prepared by this method is used on the surface of automobile glass to prevent rainy days. Will affect the driver's line of sight, increasing safety and aesthetics

Embodiment Construction

[0020] Put 1~2kg of fresh lotus leaves in an oven at 60~70°C for 10~12 hours, grind them, soak them in water, add cellulase to them, and filter them for 1~2 hours; Add 2L of absolute ethanol, reflux at 60°C for 7~8h, filter after the reflux is completed; peel 1~2kg of flax fiber, bleach with 0.6ml / L sodium hypochlorite solution, dry after bleaching, and then grind. The finished flax fiber and the above-mentioned lotus leaf filter residue are put into water and soaked for 24 ~ 36h. After soaking, 0.5 ~ 0.8g calcium sulfate and 10 ~ 12g potassium iodide are added to it, and filtered with gauze to obtain the mixed solid of lotus leaf and flax fiber. Dry in an oven at 60~70°C; take 300~500g of the above mixed dry solid and 80~100g of glycerin into distilled water, heat up to 95°C while stirring, and stir for 1 hour with a magnetic stirrer to obtain a uniform solution; weigh 100 Add ~150g of polyethylene terephthalate resin into the above solution, heat to 100~120°C, stir for 2 hou...

Abstract

The invention relates to a preparation method of an automobile hydrophobic glass film, belonging to the field of material films. In order to solve the technical problem that the existing automobile screen wiper influences the sight of the driver in the use process in rainy days and can leave nonuniform wiping traces on the glass surface, the invention provides a preparation method of an automobile hydrophobic glass film. The method comprises the following steps: preparing a film from a lotus leaf-flax fiber mixed solid and a polyethylene terephthalate resin, and carrying out corona surface treatment to obtain the film which is hydrophobic. When being used on the automobile glass surface, the prepared film can not influence the sight of the driver in rainy days, and enhances the safety and aesthetic property.

Description

technical field [0001] The invention relates to a method for preparing an automobile hydrophobic glass film, belonging to the field of material films. Background technique [0002] In recent years, the research on superhydrophobic materials has made great progress. Nano-superhydrophobic materials have more and more extensive application prospects due to their superior performance and super hydrophobic ability. Wettability of solid surface and main index Wettability refers to the characteristic that liquid can gradually penetrate into or adhere to the solid surface when the liquid is in contact with the solid surface. Wettability is one of the important properties of solid surfaces. [0003] The contact angle is the angle held by a liquid droplet in thermodynamic equilibrium on a solid surface. Determined by the end of the beading curve at the liquid-solid-gas junction and the contact point of the solid surface. According to the degree of wetting of water on the solid surf...
