Description

Technical Field

[0001] The utility model relates to the technical field of spray painting advertising materials, in particular to a blend-modified POE vehicle body sticker. Background Technique

[0002] The vehicle body film is attached to the surface of the car paint through a polymer material to achieve the purpose of protecting the original paint and decorating the vehicle body, and can be easily removed at any time, which forms a sharp contrast with traditional paint surface chemical changes such as glazing, coating, and painting. The vehicle body film is a high-performance low-viscosity polyvinyl chloride film, which has the property of fully fitting the surface of the car paint and various interior substrates, and has many advantages such as being more convenient for construction, stronger flexibility, durability, chemical corrosion resistance, and light impermeability. It can effectively ensure accurate, seamless, and bubble-free perfect covering when facing the curved vehicle body surface during the construction process, and will not cause any damage to the car paint. On the contrary, it will fully protect the original car paint of the vehicle.

[0003] At present, the vehicle body sticker film mainly uses polyvinyl chloride (PVC) materials, and a small amount uses polypropylene (PP), polyester (PET, TPU), paper and other materials. Because the durability and cost-effectiveness of PVC have great advantages compared with other materials, this makes it have a high position in the use of mask raw materials. However, PVC has serious deficiencies in terms of environmental protection and plasticity. PVC materials may produce harmful substances during the production and treatment processes, which do not meet environmental protection requirements. And in some spray painting methods, such as solvent-based spray painting and weak solvent-based spray painting, the ink absorption is slow and the drying is slow, resulting in poor spray painting effects. Although the two materials of PP and PET are environmentally friendly, due to their too strong rigidity, they are prone to creases and cannot be applied to concave and convex curved surfaces. TPU vehicle stickers have extremely high toughness and very high tensile strength, but their cost is too high, and TPU vehicle stickers are generally not used. Therefore, it is necessary to develop a new type of environmentally friendly material vehicle body sticker to solve these problems. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. For this blend-modified POE vehicle sticker, a thermoplastic elastomer material POE is used to replace the traditional PVC mask. POE has high tensile strength, good dimensional stability, lower rigidity than PP and PET, and no creases are generated when bent. Compared with the traditional PVC vehicle sticker, this product is environmentally friendly and degradable, and the viscosity of the product also has good stability and will not decay with the increase of the placement time. The toughness of the product is better than that of PP and PET, and no creases are generated when bent. It can be applied to concave and convex curved surfaces. The product cost is lower than that of TPU vehicle stickers, and the cost performance is high. A coating is modified on the surface of POE to make up for the defect that POE itself has no ink-absorbing ability.

Since PET has high tensile strength and strong toughness, and is a highly crystalline polymer, no additives are required during the production process to achieve processing, and it has good dimensional stability at both high and low temperatures. However, PET does not have ink absorption ability. Therefore, a polyurethane coating is used to assist in compatible solvent-based, weak solvent-based, UV, and Latex spraying forms.

[0028] Working principle: This blended and modified POE vehicle sticker uses a thermoplastic elastomer material POE to replace the traditional PVC mask. POE has high tensile strength, good dimensional stability, lower rigidity than PP and PET, and no creases are generated during bending. Compared with traditional PVC vehicle stickers, this product is environmentally friendly and degradable, and the adhesiveness of the product also has good stability and will not decay with the increase of placement time. The toughness of the product is better than that of PP and PET, and no creases are generated during bending. It can be applied to concave and convex curved surfaces. The product cost is lower than that of TPU vehicle stickers, and the cost performance is high. A coating is modified on the surface of POE to make up for the defect that POE itself has no ink-absorbing ability. It can be compatible with solvent-based, weakly solvent-based, UV spraying forms. The sprayed picture effect is good, and the color is more vivid than that of traditional economy PVC vehicle stickers. The coating has strong adhesion to the mask surface and has good weather resistance and can be used for outdoor posting applications. This blended and modified POE vehicle sticker uses a PET mask to prepare a one-way perspective sticker. Because PET has high tensile strength and strong toughness, PET is a highly crystalline polymer and no additives are required during the production process to achieve processing. It has good dimensional stability at high and low temperatures. However, PET does not have ink-absorbing ability. Therefore, a polyurethane coating is used to assist in being compatible with solvent-based, weakly solvent-based, UV, and Latex spraying forms. Through laboratory formulation, the coating has good fastness, is scratch-resistant and not easy to fall off, and has excellent weather resistance. The pictures sprayed by the 4 spraying methods can achieve the effects of bright colors and uniform ink dots. The backing paper of this product uses a three-layer structure, which can prevent problems such as clogging of holes during UV spraying and arching during Latex spraying.
