Problems solved by technology

[0002] The surface of the existing car window film does not have anti-fog function. In the cold winter or rainy season, especially in bad weather, the water vapor in the hot air inside the car will form fog droplets on the cold glass surface, which greatly reduces the visible light transmission of the glass. Transient, affecting the driver's field of vision, leading to traffic accidents
Because there is no hot air from the engine in electric vehicles, it is necessary to turn on the air conditioner to defog, and the power consumption of turning on the air conditioner to defog will greatly increase

Embodiment 1

[0026] The invention discloses a method for preparing a heat-insulating anti-fog film agent, which comprises the following steps:

[0027] Step 1 The preparation of heat insulation layer resin is to add 15g of pentahydroxypolyoxypropylene ether and maleic acid-polyacrylic acid copolymer to the mixed solution made of 60g of methyl isobutyl ketone and tetrahydrofuran according to the mass ratio of 5:1. A mixture made with a ratio of 3:1, 10g of hexamethylene diisocyanate trimer, stirred at 30°C for 8h, and then added with 5g of nano-silica particles and indium tin oxide at a mass ratio of 1:1 The mixture and 0.2g polyether polyester modified organosiloxane are stirred evenly to obtain the heat insulating layer resin;

[0028] The second step is to mix and hydrolyze N-(2-aminoethyl)-3-aminopropylmethyldimethoxysilane and hydrochloric acid, adjust the pH value to 5.0-7.0, and add chemical auxiliary formamide, ethyl alcohol to the hydrolyzate Glycol, glycerin and calcium oxide, fo...

Embodiment 2

[0033] A method for preparing a heat-insulating anti-fog film agent, comprising the steps of:

[0034] Step 1 The preparation of heat insulation layer resin is to add 30g of pentahydroxypolyoxypropylene ether and maleic acid-polyacrylic acid copolymer to the mixed solution made of 90g of methyl isobutyl ketone and tetrahydrofuran according to the mass ratio of 5:1. The mixture made at a ratio of 3:1, 30g of polyisocyanate, stirred at 60°C for 2h, and then 18g of nano-silica particles and gallium zinc oxide at a mass ratio of 2:1 and 2g of polyether polyester were added Modified organosiloxane, after stirring evenly, the heat insulation layer resin can be obtained;

[0035] The second step is to mix and hydrolyze γ-mercaptopropyltrimethoxysilane with hydrochloric acid, adjust the pH value to 5.0-7.0, and add chemical auxiliary formamide, ethylene glycol, glycerol and calcium oxide, formamide, ethyl alcohol to the hydrolyzate. Glycol, glycerin and calcium oxide are added accord...

Embodiment 3

[0040] A method for preparing a heat-insulating anti-fog film agent, comprising the steps of:

[0041] Step 1 The preparation of heat insulation layer resin is to add 20g of pentahydroxypolyoxypropylene ether and maleic acid-polyacrylic acid copolymer to the mixed solution made of 75g of methyl isobutyl ketone and tetrahydrofuran according to the mass ratio of 5:1. A mixture made with a ratio of 3:1, 20g of hexamethylene diisocyanate trimer, stirred at 50°C for 4h, and then added with 12g of nano-silica particles and zinc gallium oxide at a mass ratio of 2:1 The mixture and 1g of polyether polyester modified organosiloxane are stirred evenly to obtain the heat insulating layer resin;

Abstract

The invention relates to a preparation method of a heat-insulating anti-fogging film, which is characterized by comprising the following steps: 1, preparing a heat-insulating layer resin; 2, preparing an anti-fogging layer material; and 3, preparing the heat-insulating anti-fogging film on the surface of glass. According to the invention, the glass is treated by using a coupling agent before film coating, thus increasing the binding force between the film and the glass substrate. According to the invention, the anti-fogging layer material uses a polyurethane resin and a chemical assistant, so that the whole film has better oil resistance, toughness, wear resistance, aging resistance and binding property, and the mechanical property is enhanced; and meanwhile, the whole film has anti-fogging property for longer time.

Description

technical field [0001] The invention belongs to the field of heat-insulation and anti-fog film preparation, in particular to a method for preparing a heat-insulation and anti-fog film used on the surface of automobile glass. Background technique [0002] The surface of the existing car window film does not have anti-fog function. In the cold winter or rainy season, especially in bad weather, the water vapor in the hot air inside the car will form fog droplets on the cold glass surface, which greatly reduces the visible light transmission of the glass. Transient, affecting the driver's field of vision, leading to traffic accidents. In an electric vehicle, since there is no hot air from the engine, the air conditioner needs to be turned on for defogging, and the consumption of electric energy consumed by turning on the air conditioner for defogging will greatly increase. Therefore, it is very important to develop a spontaneous anti-fog technology with long-term effect. Cont...
