Description

Technical Field

[0001] This application relates to the technical field of automotive decoration materials, and particularly to a composite material for automotive interior trim. Background Art

[0002] With the development of the times, cars have evolved from simple means of transportation to mobile spaces for people's lives. Therefore, people's requirements for the interior space of cars are also evolving. As a result, automotive interior materials have gradually evolved from traditional materials such as genuine leather to various composite materials, because only composite materials can meet the trend of diversified and personalized needs. For automotive interior materials, they need to meet the different aesthetic requirements of various users, including high-class, luxurious, simple, and colorful. Correspondingly, people not only put forward requirements for the visual beauty of automotive interior materials, but also for the tactile feeling. Existing automotive interior materials still cannot meet the user needs of these new trends, or the production cost of meeting these personalized requirements is extremely high. Summary of the Utility Model

[0003] In view of this, the technical problem to be solved by this application is to provide a composite material for automotive interior trim to solve the problems of insufficient richness and diversification in the experience of existing automotive interior products, and the problem of being unable to produce personalized interior composite materials at a relatively low cost.

[0004] To this end, this application proposes a composite material for automotive interior trim, including:

[0005] A basic layer, made of transparent plastic material; the upper surface of the basic layer includes a first pattern layer formed after multi-layer screen printing, and the thickness of the first pattern layer is greater than 0.05 mm; the first pattern layer is a UV ink layer, and the first pattern layer forms a concave-convex feeling on the upper surface of the basic layer; the basic layer is preformed into the required shape by high-pressure thermoforming; and an injection layer, arranged on the lower surface of the basic layer to form the basic thickness and strength of the composite material.

[0006] The composite material for automotive interior trim provided by this application and its manufacturing process enhance the three-dimensional sense of the automotive interior composite material, providing a strong tactile feeling for users. Moreover, the combination of the protrusions on the material surface and the patterns inside the material can further enhance the aesthetic effect of the patterns, providing users with rich visual and tactile experiences. Its manufacturing process is relatively simple, and it can quickly meet the production of composite materials with different personalized needs by adjusting the production materials. This process also solves the technical drawbacks that traditional UV inks are not resistant to stretching and are easily peeled off during the IML process, thereby realizing the tactile effect in the IML process by using the high hardness characteristics of UV inks.

[0009] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0010] In the present application, the words related to directions, such as up, down, top, bottom, inside, outside, high, and low, are based on the position of the composite material in the normal use state as the reference position.

[0011] In order to provide a personalized, tactile and highly productive automotive interior composite material, the present application provides an automotive interior composite material, including:

[0012] A basic layer, made of transparent plastic material; the upper surface of the basic layer includes a first pattern layer formed by multi-layer screen printing, and the thickness of the first pattern layer is greater than 0.05 mm; the first pattern layer is a UV ink layer, and the first pattern layer forms a concave-convex feeling on the upper surface of the basic layer; the basic layer is preformed into the required shape by high-pressure thermoforming;

[0013] An injection molding layer, arranged on the lower surface of the basic layer to form the basic thickness and strength of the composite material.

[0014] In at least one of the embodiments, a second pattern layer is included below the basic layer, and the second pattern layer includes a pattern formed by superimposing multi-layer screen printing.

[0015] In at least one of the embodiments, the pattern of the second pattern layer corresponds to the pattern of the first pattern layer.

[0016] In at least one of the embodiments, the thickness of the first pattern layer is between 0.05 mm and 0.2 mm.

[0017] The following will describe in detail the specific implementation process of the embodiments of the present application with reference to the accompanying drawings:

[0018] As Figure 1 shown, it is a schematic flow chart of the manufacturing process of the automotive interior composite material according to one of the embodiments, including the steps:

[0019] A. First, select a transparent plastic sheet as the basic layer;

[0020] If the back side of the plastic sheet also needs to be printed, then the pattern on the back of the plastic sheet is printed before printing on the front side to form a second pattern layer, and then the second pattern layer is baked and cured; the pattern of the second pattern layer corresponds to the pattern of the first pattern layer; the second pattern layer can be printed with ordinary ink or UV ink.

[0021] B. Then, multi-layer screen printing is performed on the front side of the plastic sheet with UV ink and dried to form a first pattern layer. The thickness of the first pattern layer is greater than 0.05 mm, and the first pattern layer forms a convex and concave feeling on the upper surface of the basic layer; at this time, the first pattern layer is not UV cured;

[0022] C. The plastic sheet is placed in a mold for high-pressure vacuum forming preforming;

[0023] D. Then, the plastic sheet is UV cured; and then die-cut to become the required shape; the shape includes but is not limited to different sizes, shapes, streamline features, etc. of different parts inside the car;

[0024] E. The plastic sheet is placed in an injection mold for backside skeleton injection molding to form the basic thickness and strength of the composite material.

[0025] In this application, the UV curing time and sequence of the pattern layer formed after UV ink printing are arranged after high-pressure vacuum forming preforming. Besides forming the convex and concave feeling on the surface of the plastic sheet, the UV curing time and sequence are postponed to after high-pressure vacuum forming preforming, effectively ensuring the firmness of the UV ink pattern and avoiding the shedding of the UV ink pattern.

[0026] As Figure 2 shown, a cross-sectional view of an automotive interior composite material is provided in another aspect of this application, including: a basic layer 1, made of transparent plastic material; on the upper surface of the basic layer 1, there is a first pattern layer 4 formed by multi-layer screen printing. The thickness of the first pattern layer 4 is greater than 0.05 mm; preferably, the thickness of the first pattern layer 4 is between 0.05 mm and 0.2 mm, such as 0.1 mm, 0.15 mm, 0.18 mm, etc.; the first pattern layer 4 is a UV ink layer, and the first pattern layer 4 forms a convex and concave feeling on the upper surface of the basic layer 1, enhancing the feel of the automotive interior composite material. The basic layer 1 is formed into the required shape after high-pressure vacuum forming preforming and die-cutting; between the basic layer 1 and the injection layer 3, there is also a second pattern layer 2, and the second pattern layer 2 is a pattern formed by multi-layer screen printing superposition. The pattern of the second pattern layer 2 corresponds to the pattern of the first pattern layer 4, making the composite material form a unique three-dimensional sense of space. The second pattern layer 2 can also have different colors and different pattern styles from the first pattern layer 4. Below the basic layer 1, there is also an injection layer 3, which is the skeleton structure of the automotive interior composite material to form the basic thickness and strength of the composite material.
