Embodiment 1

[0021] Prepare 100kg glasses antifogging agent, the consumption of each raw material is as follows:

[0022] Methyl trifluoropropyl silicone oil 2kg,

[0023] Isopropanol 5kg,

[0024] 1,5 pentanediol 2kg,

[0025] Sodium dodecylbenzenesulfonate 2kg,

[0026] The balance is water.

[0027] The preparation method is as follows:

[0028] (1) Add 2kg of sodium dodecylbenzenesulfonate to 89kg of water and stir to obtain a uniform liquid;

[0029] (2) Slowly add 2kg of methyl trifluoropropyl silicone oil to the liquid in step (1), and stir to obtain a uniform liquid;

[0030] (3) Add 5kg of isopropanol and 2kg of 1,5-pentanediol to the liquid obtained in step (2), and stir evenly to obtain an antifogging agent for glasses.

Embodiment 2

[0032] Prepare 100kg glasses antifogging agent, the consumption of each raw material is as follows:

[0033] Methyl trifluoropropyl silicone oil 5kg,

[0034] Isopropanol 8kg,

[0035] 1,5 pentanediol 5kg,

[0036] Sodium dodecylbenzenesulfonate 5kg,

[0037] The balance is water.

[0038] The preparation method is as follows:

[0039] (1) Add 5kg of sodium dodecylbenzenesulfonate to 77kg of water, and stir to obtain a uniform liquid;

[0040] (2) Slowly add 5kg of methyl trifluoropropyl silicone oil to the liquid in step (1), and stir to obtain a uniform liquid;

[0041] (3) Add 8kg of isopropanol and 5kg of 1,5-pentanediol to the liquid obtained in step (2), and stir evenly.

[0042] The anti-fogging agent for glasses of the present invention can be filled in a small watering can and sprayed for use, and then the lens is wiped evenly with a clean cloth, and dried; it can also be used as an anti-fogging agent after soaking a cloth or paper towel with strong adsorpti...

Abstract

The invention relates to the field of antifogging agents for glasses, in particular to an antifogging agent for the glasses and a preparation method thereof. The antifogging agent consists of the following raw materials in percentage by weight: 2 to 5 percent of methyl trifluoropropyl silicone oil, 5 to 8 percent of isopropanol, 2 to 5 percent of 1,5-pentanediol, 2 to 5 percent of sodium dodecyl benzene sulfonate and the balance of water. The preparation method of the antifogging agent for the glasses comprises the following steps of: (1) adding the sodium dodecyl benzene sulfonate into the water and stirring to obtain uniform liquid; (2) slowly adding the methyl trifluoropropyl silicone oil into the liquid in the step (1) and stirring to obtain uniform liquid; and (3) adding the isopropanol and the 1,5-pentanediol into the liquid in the step (2) and uniformly stirring. The invention has the advantages that: the antifogging effect is improved and antifogging time is prolonged; the process is simple, a product has low cost and the raw materials are basically nontoxic and cannot harm eyes; the product also has the function of cleaning the glasses; and the water is taken as a solvent, so explosion risk is avoided, and the product is convenient to carry.

Description

technical field [0001] The invention relates to the field of antifogging agents for glasses, in particular to an antifogging agent for glasses, and also relates to a preparation method of the antifogging agent. Background technique [0002] People who wear glasses will have this experience. When entering a high temperature environment from a low temperature environment, a layer of fog will condense on the glasses, which will make it difficult to see clearly. You must wipe the glasses; After wearing a mask to cover your nose, the hot air from your nose will also condense when it encounters cold glasses, making it difficult to see the road, which is very dangerous for people driving vehicles. Later, someone invented the anti-fog liquid for glasses. After being evenly applied to the lens, it can prevent the generation of fog to a certain extent, but many effects are not very satisfactory. Especially close to the sensitive part of the eyes, we must be more cautious in the selec...
