Technical Field

The invention relates to the field of vehicle-mounted player panels, in particular to an IML (in-mold labeling) integrated panel of a vehicle-mounted player and a preparation process thereof.

Background

The IML panel of the existing vehicle-mounted player on the market is generally a full-black panel, in order to increase the attractiveness and meet the requirements of consumers, a decorative edge is required to be added on the peripheral edge of the IML panel, and the IML panel is usually provided with an independent electroplated part at present. The disadvantages of such a design are: 1. when the independent decorative electroplated part is assembled, a gap is generated between the panel and the decorative electroplated part, and the integrated appearance effect is poor; 2, the independent decorative electroplated part needs to be separately provided with a die, so that the cost is higher.

In the field, the metallic paint coating has poor adhesion, which easily causes the metallic paint coating to be washed off and fall off in subsequent high-temperature and low-temperature processing procedures, thus resulting in low product yield. And the adhesive force between the metal paint coating and the membrane is poor, so that the membrane is easy to fall off in the use at high temperature and low temperature.

Therefore, the technical personnel in the field are dedicated to develop the vehicle-mounted player IML integrated panel which has good decorative appearance effect, improves the appearance, saves the production cost and the manufacturing cost, and improves the yield and the product quality.

Disclosure of Invention

In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide an IML integrated panel of a vehicle-mounted player.

In order to achieve the purpose, the invention provides an IML integrated panel of a vehicle-mounted player, which comprises a membrane, wherein a groove is punched on the membrane close to the edge of the membrane, the edge of the membrane is punched into a bent edge, a metal paint coating is printed on the membrane between the back of the groove bottom of the groove and the inner side of the bent edge, the distance between the outer end of the metal paint coating and the end part of the bent edge is L, a black paint coating is printed on the membrane at the inner end of the metal paint coating, an anti-impact paint layer is also printed on the metal paint coating, and transparent plastic layers are arranged on the bent edge, the anti-impact paint layer and the black paint coating.

Further, the L distance is 0.5mm-1.5 mm. Due to the distance design, the strength requirement of the transparent plastic layer on the adhesive force of the diaphragm can be met, and certain attractive degree can be guaranteed.

Further, the metallic paint coating is a silver metallic paint coating. The silver metal decorative border can be obtained by using a silver metal paint coating.

Further, the thickness of the membrane is not less than 0.38 mm. A large number of tests prove that when the diaphragm is smaller than 0.38mm, the impact resistance of the metal paint coating is weaker, the ink flushing condition is easy to occur, namely, in the subsequent injection molding processing, the metal paint coating is easy to flush by hot flow injection molding liquid, when the diaphragm is 0.38mm or more, the adhesive force of the diaphragm to the metal paint coating is stronger, and the metal paint coating is stable.

Further, the diaphragm is a composite PC/PMMA diaphragm. The surface of the composite PC/PMMA film has better hardness, does not change color under ultraviolet irradiation and is not easy to scratch.

Further, the L distance is 1 mm. Due to the distance design, the strength requirement of the transparent plastic layer on the adhesive force of the diaphragm can be met, and the attractiveness can be guaranteed.

Furthermore, a black paint coating is also arranged between the membrane at the bent edge and the transparent plastic layer.

The invention also provides a process for preparing the IML integrated panel of the vehicle-mounted player, which comprises the following steps:

s1, after the membrane is baked and cleaned, the membrane is placed in a tool clamp, a decorative edge area is reserved, black paint is printed in a panel area and an edge area of the membrane by using a film to form a black paint coating, the printed membrane is placed in a full-automatic baking line to be dried, and the black paint coating is fixed;

s2, blowing, dedusting and cleaning the diaphragm printed with the black paint in the step S1, placing the diaphragm in a tool clamp, printing metal paint on a reserved decorative edge area by using a film to form a metal paint coating, keeping a distance of L between the edge area of the diaphragm, placing the printed diaphragm in a full-automatic baking line for drying, fixing the metal paint, blowing and dedusting again after drying, and repeating the operation twice;

s3, blowing, dedusting and cleaning the diaphragm printed with the metal paint in the step S2, placing the diaphragm in a tool clamp, printing the anti-impact paint on the surface of the metal paint by using a film, placing the printed diaphragm in a full-automatic baking line for drying, fixing the anti-impact paint for drying, blowing for dedusting again, and repeating the operation eight times;

s4, performing punch forming on the diaphragm by using a high-temperature die by using a high-temperature plastic softening deformation principle; punching an upper film and a lower film oppositely, punching a groove on the film at the position of printing the metal paint coating, and bending and punching the edge of the film to form a bent edge;

s5, performing air blowing dust removal on the diaphragm formed in the step S4, and after cleaning, placing the diaphragm into a mold cavity of an injection mold to be injection-molded into a transparent plastic layer;

and S6, detecting the appearance of the product, and boxing and warehousing the product after the product is qualified by coating a protective film on two sides.

Further, the drying temperature of the membrane in the S1, the S2 and the S3 in the full-automatic drying line is 85 ℃, and the drying time is 3-5 hours.

Further, the L distance is 1 mm.
