As can be seen from fig. 3, the film prepared in comparative example 1 had poor visual layering and 3D visual effects, and had no "annual ring of tree" layering.
2. Tensile Property test of film
The films obtained in examples 1 to 3 and comparative example 1 were used, and the tensile strength of the films was measured in accordance with a conventional method, and the results are shown in Table 1.
TABLE 1
| Example 1 | Example 2 | Example 3 | Comparative example 1 | |
| Tensile Strength (MPa) | 28 | 25 | 27 | 23 |
As can be seen from Table 1, the tensile properties of the films produced in inventive examples 1-3 are significantly better than those of comparative example 1.
Claims (10)
1. The film is characterized by sequentially comprising an ink printing layer, a PVC extinction film layer and an ink printing layer from top to bottom;
the raw material components for preparing the PVC extinction film layer comprise PVC and extinction powder;
the raw material components for preparing the ink printing layer comprise ester, PVC and ketone, and the ester at least comprises two different esters.
2. The film of claim 1, wherein the ester comprises an acrylate ester and a butyl acetate ester; the raw material components for preparing the ink printing layer also comprise a water-resistant cross-linking agent.
3. The film of claim 2, wherein the acrylate is selected from at least one of methyl acrylate, ethyl acrylate, methyl 2-methacrylate, or ethyl 2-methacrylate.
4. The film according to claim 1, wherein the ketone is selected from acetone and/or butanone.
5. The film of claim 1, wherein the raw material components for preparing the PVC matte film layer further comprise at least one of a plasticizer, a barium zinc stabilizer, an internal slip agent, and a processing aid.
6. The film of claim 1, comprising, from top to bottom, an ink printed layer, a PVC matte film layer, an ink printed layer, a PVC middle layer, and a PVC subbing layer.
7. The film according to claim 5, wherein the raw material components for preparing the PVC matt film layer comprise, by weight, 80-90 parts of PVC, 10-20 parts of matting powder, 15-25 parts of plasticizer, 1-5 parts of barium-zinc stabilizer, 1-2 parts of internal lubricant and 0.1-1 part of processing aid.
8. The film according to claim 2, wherein the raw material components for preparing the ink printing layer comprise, by weight, 12-18 parts of acrylate, 45-55 parts of butyl acetate, 12-18 parts of PVC, 8-12 parts of ketone and 8-12 parts of an auxiliary agent.
9. A method of producing a membrane as claimed in any one of claims 1 to 8, comprising the steps of:
mixing the raw material components for preparing the PVC extinction film layer, carrying out fusion and calendering to form a film, thus obtaining the PVC extinction film, then respectively printing the raw material components for preparing the ink printing layer on the upper surface and the lower surface of the PVC extinction film, and drying to obtain the PVC extinction film layer and the ink printing layer;
respectively mixing the raw material components for preparing the PVC middle layer and the PVC bottom supporting layer, carrying out fusion and calendering to form a film, preparing a PVC middle layer film and a PVC bottom supporting layer film, then sequentially stacking the PVC extinction film layer, the PVC middle layer film and the PVC bottom supporting layer film from top to bottom, and laminating to obtain the film.
10. Use of a film according to any one of claims 1 to 8 in the decorative field.
