Description

Technical Field

[0001] The invention belongs to the field of materials, and in particular relates to a wear-resistant and precipitation-resistant metallic color gas mold material and a preparation method thereof. Background Art

[0002] Inflatable model material is the abbreviation of inflatable model material, which refers to the materials used in all inflatable products, such as simulated inflatable model products, multifunctional inflatable tents, inflatable entertainment cities, inflatable toys, etc. With the vigorous development of fields such as architectural decoration and leisure and entertainment industries, higher requirements are placed on the aesthetics and innovation of inflatable model materials, and metallic PVC inflatable model materials have shown great application potential with their unique metallic luster and eye-catching visual effects. However, the poor compatibility between metallic pigments and PVC resins in traditional preparation processes leads to the problem of pigment precipitation during the use of the material, which seriously affects the aesthetics, durability and market acceptance of the product. Therefore, how to solve the precipitation problem of metallic PVC inflatable model materials and at the same time improve their wear resistance to meet the market's growing demand for high quality is a problem that needs to be solved urgently. Summary of the invention

[0003] The purpose of the present invention is to provide a wear-resistant and precipitation-resistant metallic color inflatable mold material and a preparation method thereof. The metallic color inflatable mold material not only has a clear pattern and good visual effect, but also the metallic pigment is not easy to fall off, and has good wear resistance and corrosion resistance, which can meet the needs of long-term use.

[0004] To achieve the above object, the present invention adopts the following technical solution: A wear-resistant and precipitation-resistant metallic color inflatable mold material comprises, from bottom to top, a base material, a metallic color decorative layer printed on the base material, and a transparent PVC film layer attached to the metallic color decorative layer.

[0005] Furthermore, the substrate is a polyester fiber mesh.

[0006] Furthermore, in parts by weight, the ink raw materials for preparing the metallic color decorative layer include: 100 parts of joint ink, 20-30 parts of solvent, 5-8 parts of metallic pigment, and 3-5 parts of isocyanate adhesive.

[0007] Furthermore, the raw materials for preparing the transparent PVC film layer include, by weight: 100 parts of PVC resin, 50-60 parts of plasticizer, and 3-4 parts of barium zinc stabilizer.

[0008] The preparation method of the metallic color gas mold material comprises the following steps: 1) Printing technology is used to form a metallic decorative layer on one side of the substrate; 2) evenly coating the paste on the metallic decorative layer formed in step 1), and drying and plasticizing the paste; 3) preparing a transparent PVC film layer by calendering; 4) Using a laminating machine, the transparent PVC film layer obtained in step 3) is laminated on one side of the substrate coated with the paste in step 2), and after cooling, the metallic color inflatable mold material is obtained.

[0009] Furthermore, the raw materials of the paste in step 2) include, by weight: 100 parts of PVC paste resin, 80-90 parts of plasticizer, 2-5 parts of modified rosin, 2-3 parts of barium zinc stabilizer, and 2-4 parts of isocyanate adhesive. The modified rosin includes at least one of hydrogenated rosin and maleic rosin.

[0010] Furthermore, the coating amount of the paste in step 2) is 50-100 g / m 2 .

[0011] Furthermore, in step 2), the temperature of the drying and plasticizing is 140-160° C., and the time is 2-4 minutes.

[0012] Furthermore, in step 4), the laminating pressure is 30-35 kgf, the laminating temperature is 170-180° C., and the laminating roller speed is 5-16 m / min.

[0013] The significant advantages of the present invention are: (1) The ink decoration layer in traditional metallic color inflatable mold materials is generally directly exposed to the outside and in direct contact with the external environment, which is prone to ink shedding due to scratches. In addition, due to its poor wear resistance, it will affect the overall surface effect of the material. The present invention laminates a transparent PVC film layer on the metallic color decoration layer as a protective layer, which can effectively solve the problem of easy precipitation and shedding of metallic pigments in the use of existing metallic color inflatable mold materials, and can improve the color saturation and glossiness of the material, so that it has a good visual effect.

[0014] (2) The present invention can effectively improve the wear resistance and corrosion resistance of the material by arranging the PVC film layer on the outermost surface of the air mold material.

[0015] (3) The present invention uses modified rosin as a reinforcing agent to modify the paste used in the preparation of metallic color gas mold materials, which can improve the bonding strength between the substrate containing the decorative layer and the PVC film layer. At the same time, in order to further avoid the shedding of the metallic pigment and enhance the bonding performance between the decorative layer and the substrate, modified rosin can also be added to the ink raw material.

[0016] (4) The process of the present invention is simple, and the prepared metallic color gas mold material has a long service life and can meet the needs of long-term use. BRIEF DESCRIPTION OF THE DRAWINGS
