Problems solved by technology

But they are all instant anti-fog preparations. The duration of anti-fog is short and the adhesion is poor, generally only a few days or ten days. The anti-fog effect disappears immediately after being wiped or washed with water, so it cannot be used as a long-term anti-fog. Preparation use

Embodiment 1

[0022] 0.4% by weight of TEMPO modified nano-cellulose; 1% by weight of nano-zinc oxide; 1% by weight of Tween 80; the balance is deionized water. The preparation method is as follows: adding deionized water and Tween 80 to the modified nano-cellulose, and stirring evenly; then adding nano-zinc oxide, and continuing to stir evenly. After testing, the contact angle is only 11°.

Embodiment 2

[0024] 0.1% by weight of TEMPO method modified modified nano-cellulose; 0.1% by weight of nano-silver; 2% by weight of Tween 60; the balance is deionized water. The preparation method is as follows: adding deionized water and Tween 60 to the modified nano-cellulose, and stirring evenly; then adding nano-silver, and continuing to stir evenly. After testing, the contact angle is only 14°.

Embodiment 3

[0026] 2.5% by weight of TEMPO modified nano-cellulose; 2.5% by weight of nano-titanium oxide; 5% by weight of Tween 20; the balance is deionized water. The preparation method is as follows: adding deionized water and Tween 20 to the modified nano-cellulose, and stirring evenly; then adding nano-titanium oxide, and continuing to stir evenly. After testing, the contact angle is only 13°.

Abstract

The invention provides an antibacterial and antifog spray and a preparation method and application thereof. The antibacterial and antifog spray is prepared from the following raw materials in percentage by weight: 0.1 to 2.5% of modified nanocellulose, 0.1 to 2.5% of antibacterial agent, 1 to 5% of Tween series, and the balance of deionized water. The invention also discloses a preparation methodof the antibacterial and antifog spray and application in antibacterial and antifog aspects of automobile glass. The antibacterial and antifog spray has the advantages that by using the TEMPO type modified nanocellulose as a main component, the characteristics of high specific surface area, light weight, biocompatibility and degradability are fully utilized, so that the adhesion force between theantifog spray and a substrate is increased, and the excellent antifog property and antifog time can be stilled ensured after wiping and scouring; because of easiness in breeding of bacteria under thedamp condition, after the antibacterial agent is added into the antifog spray, the antifog function and the antibacterial function are combined, and the stability of the antifog property is improved.

Description

technical field [0001] The invention relates to an antibacterial antifog spray, in particular to an antibacterial antifog spray and its preparation method and application, belonging to the field of daily chemical industry. Background technique [0002] In autumn and winter or areas with high humidity, the surface of automobile glass, glasses, glass windows, etc. will be fogged due to temperature difference or humidity, which will greatly affect the line of sight or light exposure. The common method is to use anti-fogging agent, which can be widely used in the glass windows of automobiles, ships and other transportation vehicles and various eyeglass lenses, which can effectively prevent the formation of fog and ensure that various lenses are clear and transparent. [0003] The anti-fogging agent commonly used in the market is a low molecular weight dispersant containing hydrophilic groups, which is composed of molecules with a certain molecular weight. When coated on the surf...
