Problems solved by technology

Automobiles have greatly facilitated people's lives, but they have also brought a series of traffic safety hazards. According to statistics from relevant departments, 70% of major automobile traffic accidents occurred in rainy days.
In rainy days, rainwater falls on the reflector and side glass to form a water film, which will cause the driver's vision to be blurred, the left and right to be unclear, and the distance between the front and rear to be unclear, which will easily cause safety hazards when driving or reversing
[0005] At present, there are rainproof agents coated on the outer layer of automobile window glass on the market. Most of them use silicone oil or fluorosilicone resin as the hydrophobic agent or water repellent, but their hydrophobicity and light transmission performance are average, and they are not up to the standard. The ideal effect needs to be further improved

Embodiment 1

[0030] At room temperature, first put the silica airgel into a nano-sand mill, and grind it at 2000r / min for 60min to obtain an ultrafine silica airgel powder with a particle size of ≤5 microns, and mix it with absolute ethanol at 1 : Add the high-speed disperser at a weight ratio of 4, stir with 1000r / min rotating speed for 60min, obtain the silica airgel dispersion liquid, for subsequent use; press the weight percentage of Table 1, add the weighed heptane, isomerized dodecane In deionized water, stir at 300r / min for 10min, then add the weighed silica airgel dispersion and stir at 800r / min for 50min, then add the weighed epoxy-modified acrylic resin, propylene glycol, ethylene glycol , Stir at 800r / min for 20min, put the mixed liquid into the aerosol tank, plug in the valve, seal, fill in dimethyl ether, install the spray cap, and you have it.

[0031] The product produced in Example 1 is designated as A1.

Embodiment 2

[0033] At room temperature, first put the silica airgel into a nano-sand mill, and grind it at 2000r / min for 60min to obtain an ultrafine silica airgel powder with a particle size of ≤5 microns, and mix it with absolute ethanol at 1 The weight ratio of :4 is added to a high-speed disperser, stirred at a speed of 1500r / min for 30min, and the silica airgel dispersion is obtained for subsequent use; by weight percentage in Table 1, the weighed heptane, isomerized dodecane, Add isohexane into deionized water, stir at 400r / min for 8min, then add the weighed silica airgel dispersion and stir at 1000r / min for 60min, then add the weighed epoxy-modified acrylic resin, propylene glycol, Isopropanol, stirred at 500r / min for 30min, put the mixture into the aerosol tank, plug in the valve, seal it, fill it with 1,1,1,2-tetrafluoroethane, install the spray cap, and you have it.

[0034] The product produced in Example 2 is designated as A2.

Embodiment 3

[0036] At room temperature, first put the silica airgel into a nano-sand mill, and grind it at 2000r / min for 60min to obtain an ultrafine silica airgel powder with a particle size of ≤5 microns, and mix it with absolute ethanol at 1 : Add the high-speed disperser at a weight ratio of 4, stir for 50min with 1200r / min rotating speed, obtain the silica airgel dispersion liquid, for subsequent use; press the weight percentage of Table 1, add the weighed isohexane, isododecane Stir in deionized water at 500r / min for 8min, then add the weighed silica airgel dispersion and stir at 1200r / min for 30min, then add the weighed epoxy-modified acrylic resin, isopropanol, propylene glycol , ethylene glycol, stirred at 600r / min for 25min, put the mixed solution into the aerosol tank, plug in the valve, seal, fill with nitrogen, install the spray cap, and you have it.

Abstract

The invention discloses a super-hydrophobic glass rainproof agent aerosol composition and a preparation method thereof and relates to the technical field of glass rainproof agents. According to the technical scheme, the super-hydrophobic glass rainproof agent aerosol composition comprises, by weight percentage, 2-25% of silicon dioxide aerogel dispersion liquid, 1-5% of modified acrylic resin, 5-15% of environment-friendly solvent, 5-10% of alcohol ether rainproof agent, 10-20% of propellant and the balance water. Compared with a traditional glass rainproof agent using silicone oil and silicon-fluorine resin as the hydrophobic agent, the super-hydrophobic glass rainproof agent aerosol composition has the advantages that the silicon dioxide aerogel dispersion liquid is used as the hydrophobic material, the modified acrylic resin is used as the film-forming agent, and the composition has better hydrophobicity and transparency, can be sprayed to automobile rearview mirror glass and lateral window glass and can allow rainwater to fast leave the surface of the glass in rainy days to prevent the sight from being affect and increase driving safety.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of glass rainproofing agent, and in particular relates to a superhydrophobic glass rainproofing agent aerosol composition and a preparation method thereof. [0003] 【Background technique】 [0004] With the rapid economic development, my country's car ownership has exceeded 100 million, and continues to grow. Automobiles have greatly facilitated people's lives, but they have also brought a series of traffic safety hazards. According to the statistics of relevant departments, 70% of major automobile traffic accidents occurred in rainy days. In rainy days, rainwater falls on the reflector and side glass to form a water film, which will cause the driver's vision to be blurred, the left and right to be unclear, and the distance between the front and rear to be unclear, which will easily cause safety hazards when driving or reversing.
