Description
Technical Field
The invention relates to the technical field of anti-fog cleaning products, in particular to an anti-fog cleaning glasses wet tissue and a production process thereof.
Background
People often encounter the following two problems in using glasses: firstly, dirt such as dust, fingerprints and oil stains is inevitably stuck on the lens in the using process, if the lens is not cleaned, the optical performance and imaging quality of the lens are affected, and the vision of a user is damaged to a certain extent, so that the lens is required to be cleaned frequently to keep the cleanliness and the light transmittance; secondly, many lenses have poor anti-fog properties, and when entering a high-temperature environment from a low-temperature environment or when being covered by a nose with a mask in winter, hot air sprayed out of the nose can condense on the lenses when encountering cold lenses, so that the lenses are invisible and dangerous to people driving vehicles.
For the problem of unsatisfactory antifogging effect of the lens, the current antifogging measure for the lens mainly comprises hydrophilic antifogging, namely, a layer of hydrophilic substance is coated on the surface of the lens, so that water drops spread rapidly on the surface of the lens to form a water film, and the antifogging aim is achieved. Wherein the surfactant is the hydrophilic substance most used as an anti-fog means, and when the surfactant is used for anti-fog protection of the lens, two interfaces, namely a film-water interface and a water-air interface, are formed on the surface of the lens. At the membrane-water interface, the surfactant molecules are automatically arranged into a hydrophilic outward and lipophilic inward structure on the surface of the lens, so that the surface tension of water is reduced, and water drops spread on the surface of the lens to form a continuous water film, thereby preventing the formation of mist. As the duration of action increases, the surfactant component tends to gradually migrate to the water-air interface due to the continuously formed water film, where the hydrophilic group of the surfactant molecule faces the water layer and the lipophilic group faces the air layer. If the water film is continuously thickened to a certain degree, the water film can be accumulated into drops due to the action of gravity, so that surfactant molecules adsorbed on the surface layer of the water film are directly taken away. If the water film is thin, the water film can naturally surface dry in the air. In both cases, the surfactant molecules migrate to different extents, which results in structural defects in the otherwise closely arranged anti-fog coating, degrading the anti-fog effect and shortening the anti-fog duration. Most anti-fog products on the market suffer from this problem.
The chitosan is a product of removing partial acetyl of natural polysaccharide chitin, contains a large number of primary amino groups in a side chain structure, and can carry out complexation reaction with anionic polyelectrolyte such as alginate in aqueous solution to form a high molecular semipermeable membrane formed by polyelectrolyte complex.

Comparative example 1
This comparative example is substantially the same as example 1 except that modified chitosan is not used.

This comparative example was substantially the same as in example 1 except that the amount of phthalic anhydride added was 1.0g.
Comparative example 3
This comparative example was substantially the same as in example 1 except that the amount of phthalic anhydride added was 1.5g.
Comparative example 4
This comparative example was substantially the same as in example 1 except that the amount of phthalic anhydride added was 4.0g.
Comparative example 5
This comparative example was substantially the same as in example 1 except that the amount of phthalic anhydride added was 4.5g.
Comparative example 6
This comparative example provides an anti-fog cleaning eyeglass wet wipe prepared as follows:
preparation of anti-fog cleaning solution:
the anti-fog cleaning solution comprises the following raw materials in percentage by mass: 6% of dodecyl hydroxypropyl sulfobetaine, 3% of glycerol, 35% of absolute ethyl alcohol and the balance of deionized water.
Mixing dodecyl hydroxypropyl sulfobetaine, glycerol, absolute ethyl alcohol and deionized water together according to the mass ratio, and stirring for 30min to obtain the anti-fog cleaning solution.
Preparation of antifogging cleaning glasses wet tissues:
the antifogging cleaning solution is added into non-woven fabrics through dipping according to the mass ratio of 1.5:1, and then the wet tissues are cut according to the actual required size, so that the required wet tissues are prepared.
Test case
Anti-fog effect test on anti-fog cleaning glasses wet tissues prepared in examples 1 to 3 and comparative examples 2 to 6:
the prepared antifog cleaning glasses wet tissues are uniformly smeared with round lenses, and then are placed above a water bath kettle with the temperature of 70 ℃ and the distance from the water surface to the height of 5cm. Taking down the lens after continuously fumigating for 3min, naturally airing the lens, and continuously fumigating the lens on a water bath kettle at 70 ℃ for 3min, so that the lens is reciprocated until fog appears in 10% of the area of the surface of the lens. The test results are shown in table 1 below:
TABLE 1
Note that: "-" means not hazed; "+" indicates that there is water vapor or fog on the edge, but not more than 10%; "++" indicates that more than 10% of the area is hazed.
As can be seen from the results of table 1, when chitosan and sodium alginate were not used (comparative example 6), the antifogging duration of the antifogging cleaning spectacle wet tissues was short. When the modified chitosan of the present invention is used in combination with sodium alginate and amphoteric surfactant (examples 1-3), the duration of anti-fog for the anti-fog cleaning eyeglass wet wipe is significantly increased. When the addition amount of the amino-protecting agent is controlled to control the amino-preserving amount during the modification of chitosan, the antifogging duration of the antifogging cleaning eyeglass wet tissues tends to increase and decrease with the increase of the addition amount of the amino-protecting agent. This is probably due to the fact that when the added amount of the amino protecting agent is small, the amino groups on the modified chitosan molecular chain are excessively lost in the modification process, so that the complexation reaction with sodium alginate is insufficient to form a network structure for stabilizing the amphoteric surfactant; when the added amount of the amino protective agent is large, the complex reaction of the modified chitosan and the sodium alginate is strong, so that the amphoteric surfactant is difficult to be inserted into the network structure of the chitosan and the alginate, thereby adversely affecting the stabilizing effect of the amphoteric surfactant.
