Abstract

The invention belongs to the technical field of production of antifogging agents, and discloses a novel antifogging agent for vehicles, wherein the novel antifogging agent composition comprises, by weight, 1-2 parts of brominated acetylcholine, 1-2 parts of phenacetin, 1-3 parts of sodium lauryl sulfate, 1-3 parts of sodium secondary alkylsulfonate, 1-3 parts of fatty alcohol sodium isethionate, 0.5-2 parts of coconut oil fatty acid diethanolamide, 0.5-2 parts of hydroxy synthetic alcohol polyoxyethylene, 0.5-2 parts of alkyl glycoside, 0.2-1 part of sodium citrate, 2-7 parts of glacial aceticacid, 60-75 parts of anhydrous ethanol, 8-15 parts of hard water softener, 0.2-1 part of preservative, and 16-32 parts of water. The process of the novel antifogging agent comprises selecting materials, stirring, mixing the raw materials, filtering, and preparing the finished product. According to the present invention, the novel antifogging agent can rapidly remove mist, and has substantially improved durability and substantially improved low-temperature resistance.

Description

technical field [0001] The invention relates to the technical field of production of antifogging agents, in particular to a novel antifogging agent for automobiles and a process method thereof. Background technique [0002] Fog on the glass surface greatly affects the transmission of light. The reason is that small water droplets condense on the glass surface to form many spherical tiny water droplets, and each small water droplet acts as a lens, scattering light in all directions or not. Reflect regularly so that extraneous light cannot pass through directly. Therefore, the external object image produces a blurred image that cannot be seen clearly, and the greater the curvature of the water droplet, the more obvious the scattering and irregular reflection of light, especially in the cold winter or rainy season, the water in the cab or the hot air in the car Vapor will condense into dewdrops on the cold glass surface, which will greatly reduce the light transmittance of the...

[0002] Fog on the glass surface greatly affects the transmission of light. The reason is that small water droplets condense on the glass surface to form many spherical tiny water droplets, and each small water droplet acts as a lens, scattering light in all directions or not. Reflects regularly so that extraneous light cannot pass through directly

Therefore, the external object image produces a blurred image that cannot be seen clearly, and the greater the curvature of the water droplet, the more obvious the scattering and irregular reflection of light, especially in the cold winter or rainy season, the water in the cab or the hot air in the car Vapor will condense into dewdrops on the cold glass surface, which will greatly reduce the light transmittance of the glass, affect the line of sight, bring great inconvenience to driving, and even cause danger. The existing solutions are: 1. Develop glass with poor thermal conductivity Or blow hot air on the inner surface of the glass, the purpose is not to make the temperature of the inner surface of the glass drop below the dew point; 2. Use a dehumidification device to reduce the indoor humidity; 3. Coat the glass with a layer of anti-fog film; 4. Coat the glass with a layer of anti-fog Even if water vapor condenses on the surface of the glass, it will not exist in the form of water droplets, but will be transformed into a water film with high transparency. However, the first and second methods are installed in mid-to-high-end cars and used Windshields with better anti-fog properties, but for most popular cars, such as trucks, buses, etc., this method is too expensive. The third method must be applied in the glass manufacturing process. Glass processing is inconvenient; the fourth method is to use anti-fogging agents. At present, traditional anti-fogging agents mainly include the following types: 1. Glass anti-fogging agents that form a hydrophobic coating on the glass surface after use are mainly made of metal soap, silicon , zirconium compounds and other hydrophobic substances

This kind of anti-fogging agent is generally effective, and has poor low temperature resistance, so it is inconvenient to use; 2. The glass anti-fogging agent that forms a hydrophilic coating on the glass surface after use is mainly formulated with water-soluble surfactants as the main component , the effect of this kind of anti-fogging agent is still good, but the effect durability and low temperature resistance are low. Therefore, we propose a new type of anti-fogging agent for automobiles and its process method
