Description

Technical Field

[0001] The present application relates to the technical field of packaging materials, and more specifically, to a matte oil, a preparation method and a facial mask bag using the matte oil. Background Art

[0002] Compared with traditional materials such as metal, glass, and wood, plastics have advantages that traditional materials cannot match. They are light, cheap, easy to process, and have stable chemical properties, making them popular among people. Since the emergence of plastics, they have been rapidly applied in food packaging, agriculture, construction, automobiles, aerospace, and other industries. Now, plastics are present in every aspect of human life, and humans cannot live without them.

[0003] Matte film for packaging is widely used in the printing and packaging industry. Matte film is usually made by adding matting powder to the resin coating to achieve matte effect. Since the matting powder is insoluble, it is easy to precipitate in the coating, resulting in uneven matte of the matte film. Therefore, traditional matte film requires strict control of coating viscosity and matting powder particle size, and also requires matching screen rollers to solve the problem of uneven matte of the film surface and local sagging after matte coating spraying.

[0004] In addition, when consumers use matte packaging materials, their hands tend to sweat, and the sweat and fat on their hands slide on the surface of the matte film, leaving a large number of fingerprints, which seriously affects the appearance and usability. In order to obtain a matte film that is anti-fouling and anti-fingerprint, the prior art usually electroplates a layer of fluorosilicone material on the surface of the matte layer to improve its hydrophobic and oleophobic properties, making it difficult for sweat and fat to adhere to the surface of the matte film.

[0005] Although the above-mentioned matt oil coating combined with electroplating fluorine-silicon material technology can avoid fingerprint residue to a certain extent, this technical process is complicated and the processing cost is high, making it difficult to achieve greater economic benefits. Summary of the invention

[0006] In order to overcome the shortcomings and deficiencies of the prior art, the present application provides a matte oil, a preparation method and a mask bag using the matte oil. The present application does not require the step of electroplating fluorosilicone materials, but directly applies the matte oil on the surface of the packaging film material, and only relies on the special formula of the matte oil to achieve the high adhesion performance of the matte layer on the film surface and the anti-fouling and anti-fingerprint properties of the matte film.

[0007] In a first aspect, the present application provides a matt oil, which comprises the following components in parts by weight: 50-100 parts of acrylate polymer, 10-15 parts of reactive diluent, 1-3 parts of antifouling agent, 0.1-0.5 parts of leveling agent, 0.5-1 parts of wetting and dispersing agent, 2-3 parts of photoinitiator, and 5-20 parts of matting powder;

[0082] Comparative Example 3

[0083] A matte oil, which differs from Example 1 in that the formulation does not contain an antifouling agent.

[0084] Comparative Example 4

[0085] A dumb oil, which is different from Example 1 in that the antifouling agent is prepared by the following preparation method: 104.10g (1.0mol) of methyl lactate, 350g of triethylamine, and 17.43g of KF are added to a round-bottom flask, and 165.03g (1.1mol) of hexafluoropropylene is slowly added under stirring, the temperature is controlled to 90°C, and the reaction is terminated after heating and stirring for 2.5h.

[0086] Performance testing

[0087] Preparation of matte film: PET is used as the substrate, and dust removal, corona treatment, heating and ironing treatment are carried out in sequence. Micro-concave precision coating is adopted at 3.0g / m 2 The coating amount is 1000mj / cm 2 The matte film is obtained by UV curing under UV energy.

[0088] Matt films were prepared using the matte oils prepared in Examples 1-10 and Comparative Examples 1-4, respectively, and performance tests were performed on the matte films prepared in each of the Examples and Comparative Examples.

[0089] Hardness: Based on ASTM D3363-00 "Standard Test Method for Pencil Hardness of Coatings";

[0090] Scratch resistance value: tested by ST-5600 abrasion resistance tester;

[0091] Transmittance and haze: tested with a transmittance-haze tester.

[0092] Fingerprint resistance: Press the matte film surface directly with your finger, press randomly at different positions 10 times, and observe the number of visible fingerprints remaining.

[0093] Anti-fouling performance: Use a marker pen to mark the surface of the matte film, then wipe it and observe the residual mark.

[0094] The test results are recorded in Table 1 below.

[0095]

[0096] It can be seen from the above test results that the matte film prepared in the present application has high hardness, adhesion, wear resistance, and excellent anti-fouling and anti-fingerprint properties.

[0097] By comparing Example 1 with Comparative Examples 1 and 2, it can be seen that for the matte oil formula of the present application, the selection of the acrylate polymer can affect various properties of the final paint film, especially hardness, adhesion and scratch resistance. This is mainly because the present application adds a fluorinated alkyl ester anti-fouling agent having a benzene ring. The specific selection of the acrylate polymer determines its compatibility with various additives, and also directly determines various properties of the paint film.

[0098] By comparing Example 1 with Comparative Examples 3 and 4, it can be seen that the addition of the anti-fouling agent can significantly affect the anti-fouling and anti-fingerprint properties of the paint film, and the alkyl ester anti-fouling agent with a benzene ring is better than the alkyl ester anti-fouling agent without this ring. This may be because the alkyl ester anti-fouling agent containing a benzene ring is easier to disperse in the formula and easier to combine with the raw materials, thereby giving full play to the anti-fouling performance.

[0099] The above is only the preferred implementation of the present application. The protection scope of the present application is not limited to the above embodiments. All technical solutions under the concept of the present application belong to the protection scope of the present application. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present application should also be regarded as the protection scope of the present application.
