Example Embodiment

[0026] Example 1

[0027] To prepare 100kg of antifogging agent for automobile glass, the amount of each raw material is as follows:

[0028] Methyl trifluoropropyl silicone oil 2kg,

[0029] Volatile perfluorinated oil 2kg,

[0030] Oleic acid 2kg,

[0031] 1,5 pentanediol 2kg,

[0032] Tween-80 2kg,

[0033] The balance is water.

[0034] The preparation method is as follows:

[0035] (1) Dissolve 2kg Tween-80 in 90kg water and stir until it becomes a homogeneous liquid;

[0036] (2) Mix 2kg of volatile perfluorinated oil, 2kg of oleic acid and 2kg of methyltrifluoropropyl silicone oil, and stir until a homogeneous liquid;

[0037] (3) Pour the liquid of step (2) slowly into the liquid of step (1), and stir while pouring until it becomes a uniform liquid;

[0038] (4) Pour 2 kg of 1,5 pentanediol into the liquid of step (3) and stir evenly to obtain an antifogging agent for automobile glass.

Example Embodiment

[0039] Example 2

[0040] To prepare 100kg of antifogging agent for automobile glass, the amount of each raw material is as follows:

[0042] Volatile perfluorinated oil 5kg,

[0043] Oleic acid 5kg,

[0044] 1,5 pentanediol 5kg,

[0045] Tween-80 5kg,

[0046] The balance is water.

[0047] The preparation method is as follows:

[0048] (1) Dissolve 5kg Tween-80 in 75kg water and stir until it becomes a homogeneous liquid;

[0049] (2) Mix 5kg of volatile perfluorinated oil, 5kg of oleic acid and 5kg of methyltrifluoropropyl silicone oil, and stir until a homogeneous liquid;

[0050] (3) Pour the liquid of step (2) slowly into the liquid of step (1), and stir while pouring until it becomes a uniform liquid;

[0051] (4) Pour 5 kg of 1,5 pentanediol into the liquid of step (3) and stir evenly to obtain an anti-fogging agent for automobile glass.

Abstract

The invention relates to the field of glass antifogging agents, in particular to an automotive glass antifogging agent and a preparation method thereof. The automotive glass antifogging agent consists of the following raw materials in percentage by weight: 2 to 5 percent of methyl trifluoropropyl silicon oil, 2 to 5 percent of volatile perfluoro-oil, 2 to 5 percent of oleic acid, 2 to 5 percent of 1,5-pentanediol, 2 to 5 percent of tween-80, and the balance of water. The automotive glass antifogging agent is prepared by the following steps of: (1) dissolving the tween-80 in the water, and stirring the mixture; (2) mixing the volatile perfluoro-oil, the oleic acid and the methyl trifluoropropyl silicon oil together, and uniformly stirring the mixture; (3) pouring the liquid of the step (2) into the liquid of the step (1), and uniformly stirring the mixture; (4) pouring the 1,5-pentanediol into the liquid of the step (3), and uniformly stirring the mixture. The introduction of fluorine ensures that the antifogging agent has excellent hydrophobicity and an antifogging function, the antifogging time is prolonged, and the antifogging effect is improved; furthermore, the automotive glass antifogging agent has no side effect on human bodies, and has the functions of preventing rain, cleaning glass and protecting a wiper after the automotive glass antifogging agent is coated on external glass and a back view mirror of an automobile.

Description

technical field [0001] The invention relates to the field of antifogging agents for glass, in particular to an antifogging agent for automobile glass, and also relates to a preparation method of the antifogging agent. Background technique [0002] One of the headaches for car owners in winter is that the glass inside the car is often covered by fog, which seriously hinders driving safety. The currently used glass anti-fog agents are generally composed of surfactants, alcohol solvents or ether solvents. The anti-fog time is generally 1-2 days, and the anti-fog time is short. In addition, the anti-fog effect is not very good. , When encountering heavy fog or severe cold weather, the anti-fog effect will be poor. Contents of the invention [0003] In order to overcome the deficiencies in the above technologies, the present invention provides an antifogging agent for automobile glass with good antifogging effect and long antifogging time. [0004] The invention also provides...
