Description

TECHNICAL FIELD

[0001] The application belongs to the field of materials, and particularly relates to a metal color air mold material resistant to wear and separation and a preparation method thereof. BACKGROUND

[0002] Air mold material is a short name of air-filled model material, and generally refers to materials used for all air-filled products, such as simulation air mold products, multifunctional air tents, air entertainment cities, air toys and the like. With the vigorous development of the fields of building decoration and leisure and entertainment, higher requirements are put forward for the aesthetic property and innovation of air mold materials, and the metal color PVC air mold material has huge application potential due to its unique metal luster and attractive visual effect. However, the compatibility between the metal pigment and the PVC resin is poor in the traditional preparation process, which leads to the problem of separation of the pigment in the material during use, and seriously affects the aesthetic property, durability and market acceptance of the product. Therefore, how to solve the separation problem of the metal color PVC air mold material and improve the wear resistance of the material to meet the increasing demand for high quality is a difficult problem to be solved at present. SUMMARY

[0003] The application aims to provide a metal color air mold material resistant to wear and separation and a preparation method thereof, which has clear patterns, good visual effect, and metal pigments that are not easy to fall off, and has good wear resistance and corrosion resistance, and can meet the demand for long-term use.

[0004] To achieve the above-mentioned purpose, the application adopts the following technical solutions:

[0005] A metal color air mold material resistant to wear and separation comprises, from bottom to top, a base material, a metal color decorative layer printed on the base material, and a transparent PVC film layer attached to the metal color decorative layer.

[0006] Further, the base material is a polyester fiber mesh cloth.

[0007] Further, the ink raw material for preparing the metal color decorative layer comprises, by weight, 100 parts of joint ink, 20-30 parts of solvent, 5-8 parts of metal pigment, and 3-5 parts of isocyanate adhesive.

[0008] Further, the raw material for preparing the transparent PVC film layer comprises, by weight, 100 parts of PVC resin, 50-60 parts of plasticizer, and 3-4 parts of barium-zinc stabilizer.

[0009] The preparation method of the metal color air mold material comprises the following steps:

[0010] 1) A metal color decorative layer is printed on one side of the base material by using printing technology;

[0011] 2) evenly coating the paste on the metallic color decoration layer formed in step 1) and performing drying plasticization;

[0012] 3) preparing a transparent PVC film layer by calendering;

[0013] 4) using a laminating machine to laminate the transparent PVC film layer obtained in step 3) to the side of the substrate coated with the paste in step 2), and obtaining the metallic color mold material after cooling.

[0014] Further, the raw materials for preparing the paste in step 2) include, by weight parts, PVC paste resin 100 parts, plasticizer 80-90 parts, modified rosin 2-5 parts, barium-zinc stabilizer 2-3 parts, and isocyanate adhesive 2-4 parts. The modified rosin includes at least one of hydrogenated rosin and maleated rosin.

[0015] Further, the coating amount of the paste in step 2) is 50-100 g / m 2 .

[0016] Further, the temperature for drying plasticization in step 2) is 140-160℃, and the time is 2-4 min.

[0017] Further, the pressure during lamination in step 4) is 30-35 kgf, the lamination temperature is 170-180℃, and the lamination roller speed is 5-16 m / min.

[0018] The significant advantages of the present application are:

[0019] (1) The ink decoration layer in the traditional metallic color mold material is generally directly exposed to the outside, and directly contacts with the external environment, which is easy to cause the phenomenon of ink falling off due to scratching, and the poor wear resistance will affect the overall surface effect of the material. The transparent PVC film layer is laminated on the metallic color decoration layer as a protective layer, which can effectively solve the problem of easy precipitation and falling off of the metallic pigment in the existing metallic color mold material during use, and can improve the color saturation and gloss of the material, so as to have good visual effect.

[0020] (2) The PVC film layer is arranged on the outermost surface of the mold material, which can effectively improve the wear resistance and corrosion resistance of the material.

[0021] (3) The modified rosin is used as a reinforcing agent to modify the paste used in the preparation of the metallic color mold material, which can improve the adhesion strength between the substrate containing the decoration layer and the PVC film layer. At the same time, in order to further avoid the falling off of the metallic pigment and enhance the adhesion between the decoration layer and the substrate, the modified rosin can also be added to the ink raw materials.

[0022] (4) The process is simple, and the metal color air mold material prepared has a long service life, which can meet the demand for long-term use. BRIEF DESCRIPTION OF DRAWINGS
