Problems solved by technology

Existing anti-fogging agents have high requirements for construction technology: if applied lightly, it will cause uneven application and serious glare phenomenon; if applied a little harder, the anti-fogging agent will be wiped off and the anti-fogging effect will be lost
The above-mentioned problems that existing anti-fogging agent exists have limited its popularization and application

Embodiment 1

[0022] The composition of the nano sol glass antifogging agent is: 0.1wt% of silicon oxide compound sol; 0.01wt% of camptothecin compounds with the structure shown in formula I; and 99.89wt% of water.

[0023]

[0024]

[0025] Wherein, R is selected from any one of C1-C5 alkyl group, carboxyl group, ester group and amino group.

[0026] The anti-fog agent formulated in this example can extend the anti-fog time to 8 months, which fully meets the application requirements. When the solvent is ethanol, methanol, propanol, acetone, ethyl acetate, petroleum ether, the anti-fog time of about 8 months can still be obtained.

Embodiment 2

[0028] The composition of the nano sol glass antifogging agent is: 15wt% of titanium oxide compound sol; 2wt% of camptothecin compounds with the structure shown in formula I; and 83wt% of water.

[0029]

[0030] Wherein, R is selected from any one of C1-C5 alkyl group, carboxyl group, ester group and amino group.

[0031] The antifogging agent prepared by the method can extend the antifogging time to 8 months, fully meeting the application requirements. When the solvent is ethanol, methanol, propanol, acetone, ethyl acetate, petroleum ether, the anti-fog time of about 8 months can still be obtained.

Embodiment 3

[0033] The composition of the nano sol glass antifogging agent is: 30 wt% of aluminum oxide compound sol; 4 wt% of camptothecin compounds with the structure shown in formula I; and 66 wt% of water.

[0034]

[0035] Wherein, R is selected from any one of C1-C5 alkyl group, carboxyl group, ester group and amino group.

[0036] The antifogging agent prepared by the method can extend the antifogging time to 8 months, fully meeting the application requirements. When the solvent is ethanol, methanol, propanol, acetone, ethyl acetate, petroleum ether, the anti-fog time of about 8 months can still be obtained.

Abstract

The invention discloses a nano sol glass antifogging agent. The nano sol glass antifogging agent comprises nano sol which is subjected to surface modification by using a camptothecin compound with thestructure indicated in the form I. The nano sol glass antifogging agent is convenient to clean, free of pollution, easy and simple in construction, good in antifogging effect and long in antifoggingduration (as long as 8 months), and the nano sol glass antifogging agent achieves qualitative leaps in the antifogging duration and construction compared with existing antifogging agents. The defectsof the existing antifogging agents are overcome, and the nano sol glass antifogging agent can be promoted in the fields of architecture and automobiles. The formula is shown in the specification, andin the structure, R is any one of an alkyl group with the carbon number being less than 6, a hydroxyl group, an ester group and an amidogen group.

Description

Technical field: [0001] The invention relates to a nano sol glass antifogging agent. Background technique: [0002] In autumn and winter, water mist condenses on the inner surface of the glass, causing blurred vision and affecting the vision of home and office. For example, fogging on the glass of a car poses a serious threat to the safe driving of the car. In 2015, there were more than 300,000 automobile traffic accidents in my country, among which traffic accidents caused by blurred vision due to weather accounted for about 1 / 3. Currently commonly used anti-fogging agents are surfactant-based and polymer-based anti-fogging agents. The former uses surfactants to reduce the surface tension of water so that the water mist spreads flat on the glass surface and achieves a better anti-fogging effect. The mainstream of the market, but the anti-fog time is only 2-3 days. Existing anti-fogging agents have high requirements for construction technology: if applied lightly, it will ...
