Problems solved by technology

The liquid anti-fog agent needs to be sprayed, and in most cases, it needs to be wiped with a cloth after spraying, so it is inconvenient to use, and the sprayed aerosol is likely to cause pollution and safety hazards
And the anti-fog agent is mostly composed of surfactant and water, the drying speed is slow, and the anti-fog effect is not good enough

Embodiment 1

[0029] An anti-fog liquid, which comprises 1% by mass of nanocellulose, 20% by mass of fatty alcohol polyoxyethylene ether (tergitol 15-s-7), 0.25% by mass of polyethylene oxide, 10% by mass of of ethanol, and the balance is water. Wherein, the nanocellulose is nanocellulose with negatively charged carboxyl groups on the surface, and the diameter of the nanocellulose is 3-6 nm; the length is 400-800 nanometers.

[0030] The method of using the anti-fog solution described in this example to prepare an anti-fog cloth is as follows: take the non-woven fabric of the same quality and the anti-fog solution described in this example, immerse the non-woven fabric in the anti-fog solution, and wait until the anti-fog solution is completely covered. After the non-woven fabric is absorbed, it is dried to obtain an anti-fog cloth.

[0031] Each component of the obtained anti-fog cloth accounts for the mass content of the dry weight of the nonwoven fabric: the mass content of nanocellulos...

Embodiment 2

[0034] An anti-fog liquid, which comprises 0.5% by mass of nanocellulose, 15% by mass of dodecyl glucoside, 0.5% by mass of polyacrylic acid, and the balance being water. The nanocellulose is nanocellulose with negatively charged phosphoric acid groups on the surface.

[0035] The method of using the anti-fog solution described in this example to prepare the anti-fog cloth is as follows: take the non-woven fabric and the anti-fog solution described in this example with twice the mass of the non-woven fabric, immerse the non-woven fabric in the anti-fog solution, and wait for the anti-fog solution After the fog liquid is completely absorbed by the non-woven fabric, it is dried to obtain the anti-fog cloth.

[0036] The weight content of each component of the obtained anti-fog cloth based on the dry weight of the non-woven fabric is as follows: the weight content of nanocellulose is 1%, the weight content of lauryl glucoside is 30%, and the weight content of polyacrylic acid is ...

Embodiment 3

[0039] An anti-fog liquid, which comprises 2% by mass of nanocellulose, 20% by mass of cationic fluorocarbon surfactant, 20% by mass of dodecyl glucoside, and 0.2% by mass of polyvinyl alcohol, The balance is water. The nanocellulose is nanocellulose with negatively charged phosphoric acid groups on the surface.

[0040] The method of using the anti-fog solution described in this example to prepare an anti-fog cloth is as follows: take the non-woven fabric of the same quality and the anti-fog solution described in this example, immerse the non-woven fabric in the anti-fog solution, and wait until the anti-fog solution is completely covered. After the non-woven fabric is absorbed, it is dried to obtain an anti-fog cloth.

[0041] The mass content of each component of the obtained anti-fog cloth in the dry weight of the non-woven fabric is: the mass content of nanocellulose is 2%, the mass content of cationic fluorocarbon surfactant is 20%, and the mass content of dodecyl gluco...

Abstract

The invention provides an anti-mist liquid good in anti-mist effect, an anti-mist cloth prepared from the same and a preparation method of the anti-mist cloth. The anti-mist cloth is convenient to useand long in effect duration. The anti-mist liquid comprises nano-cellulose, water-soluble macromolecules, a surfactant, a water-soluble solvent and the like, wherein the surfactant plays a role in wetting and spreading, the nano-cellulose can improve the moisture retention and water scouring resistance functions of a coating, the water-soluble macromolecules and the nano-cellulose achieve a synergistic function to improve the anti-mist effect, and the water-soluble solvent makes the anti-mist liquid dry faster.

Description

technical field [0001] The invention relates to the technical field of defogging, in particular to an anti-fog liquid, an anti-fog cloth prepared therefrom and a preparation method of the anti-fog cloth. Background technique [0002] Fogging is a problem that is often encountered in daily production. Whether it is automobile glass, surgical endoscope, bathroom mirror, freezer window, or swimming goggles, helmets, the phenomenon of fogging will be encountered during the use of greenhouses. Fog not only causes great inconvenience to life and production, but also brings great potential safety hazards. Existing anti-fog technologies generally use liquid anti-fog agents. The liquid anti-fogging agent needs to be sprayed, and in most cases, it needs to be wiped evenly with a cloth after spraying, so it is inconvenient to use, and the sprayed aerosol is likely to cause pollution and safety hazards. And the antifogging agent mostly is surfactant and water composition, and drying ...
