Description
Technical Field
The invention belongs to the technical field of new energy automobile beauty, and particularly relates to a glass antifogging agent for a new energy automobile.
Background
In rainy season or cold winter, the automobile windshield often fogs or frosts, the light transmittance of the glass is greatly reduced, the sight is influenced, great inconvenience is brought to life, and even danger can occur.
The antifogging agent is a low-molecular-weight dispersing agent containing hydrophilic groups, consists of molecules with determined molecular weight, can form a coating when coated on the surface of a transparent object, and the hydrophilic groups in the coating can adsorb water molecules in the air and form a water film when wetted and diffused on the surface of the transparent object, so that light rays penetrating through the object cannot be scattered, and the fogging phenomenon is avoided. The main component is surfactant, such as xylitol ester, sorbitol monopalmitate, lauric acid or hard resin acid monoglyceride, etc.
Currently, research on antifogging agents is in a stage of active development. With the progress of science and technology, the research of glass antifogging agents is in a complete situation due to diversified development, and various methods and principles have respective characteristics and unique features. Simple anti-fogging techniques have been mastered in the 60 s in the country, and in particular in japan performed well in this regard. For the past 90 s, surfactant-based antifogging agents have dominated, for example: an automotive glass antifogging agent for forest knight; chen 32565A glass antifogging agent and a preparation method thereof; yuanjiang glass and organic glass antifogging agent and its preparation method; well-documented multifunctional antifogging agent for optical glass, Junming, Lu Shuwu. Relatively few reports have been made on methods of coating polymer film antifogging agents and the like. Surfactant antifogging agents are generally composed mainly of surfactants, solvents, wetting agents, dispersants, and the like. The antifogging agent is simple to prepare, but the antifogging durability is poor due to the fact that water is condensed on the surface of glass and the surfactant is easy to run off, and the antifogging duration is 2-7 days generally.
Patent 201210368016.9 discloses an antifogging agent for glass, which comprises the following raw materials by weight: 0.1-0.5% of modified acrylic polymer, 2-5% of ethylenediamine derivative, 2-10% of propylene glycol ether, 0.05-0.5% of alkyl diphenyl ether disulfonate, 50-60% of water and the balance of low molecular alcohol. Patent 201210368018.8 discloses a glass antifogging agent and a preparation method thereof, which comprises the following raw materials by weight: 0.1-0.5% of modified acrylic polymer, 0.05-0.5% of high-polymerization-degree alkyl glycoside, 2-10% of dipropylene glycol ether, 50-60% of water and the balance of low-molecular alcohol. Although the antifogging agent for glass has a good antifogging effect, the antifogging time is short, the antifogging agent is not resistant to wiping, and the antifogging agent is easy to bloom under low-temperature conditions.

Experimental example 1: determination of antifogging time
Two glass rods are placed on a water bath kettle at 50 ℃ as a bracket, and an included angle of 30 degrees is formed on the horizontal plane. The glass sheet (6cm x 6cm) coated with the antifogging agent is placed on the support, and the distance between the glass sheet and the water surface is 10 cm. The intermittent fumigation method is adopted, namely when the glass sheet is completely soaked (the time is about 5min), the glass sheet is taken down, naturally dried, put on to be fumigated, and the operation is repeated until fog exists on the glass sheet, and the judgment is carried out by using the 'repeated times' before the fog appears on about 10% of the glass surface. The number of repetitions was noted. Because the temperature difference is maximum only in the morning and the evening in one day, the alternation of the dry and the wet is performed twice in the morning and the evening in one day, and the antifogging time is counted as one day by counting twice. The test results are shown in table 1:
TABLE 1 antifogging time test
Note: represents P < 0.05; represents P < 0.01.
As can be seen from table 1, the days of fog prevention for examples 1-3 and example 7 are equivalent, without significant difference, the days of fog prevention for examples 4-6 are significantly higher than for example 1, and the days of fog prevention for comparative examples 1-2 are significantly lower than for example 1.
Experimental example 2: low temperature frost prevention experiment
The glass (6 cm. times.6 cm) coated with the antifogging agent on both sides was placed at-20 ℃ and the experimental phenomenon is shown in Table 2.
TABLE 2 Low temperature Frost prevention Experimental phenomena
As can be seen from table 2, the low temperature anti-frost properties of examples 1-3 and example 7 are equivalent without significant difference, the low temperature anti-frost properties of examples 4-6 are significantly higher than example 1, and the low temperature anti-frost properties of comparative examples 1-2 are significantly lower than example 1.
Experimental example 3: measurement of light transmittance
The antifogging agent is coated on a glass slide (5cm multiplied by 1cm), the glass slide is placed in the light path of a UV-2000 type spectrophotometer, and the light transmittance is measured under visible light (the wavelength range is 400 nm-750 nm). The measurement results are shown in table 3:
TABLE 3 measurement results of light transmittance
Note: represents P < 0.05; represents P < 0.01.
As can be seen from table 3, the light transmittances of examples 1 to 3 and example 7 were equivalent without significant difference, the light transmittances of examples 4 to 6 were significantly higher than example 1, and the light transmittances of comparative examples 1 to 2 were significantly lower than example 1.
The antifogging agent for the new energy automobile can prevent fog at low temperature and high temperature, can prevent frost at ultralow temperature of-20 ℃, has long antifogging time, can form a protective film on the surface of automobile glass, and can prevent failure after physical actions such as wiping and the like.
