The injection 110 is a component for forming a case of a component mounted on the vehicle 1, and may be made of at least one material of polycarbonate, ABS resin, or ABS synthetic resin. However, the material of the injection material 110 is not limited thereto, and a structure and vehicle capable of depositing a primer layer 120, a colored layer 130, and a hard coating layer 140, which will be described later, as an upper surface of the injection material 110. Depending on the installation of (1), any modification or change will be possible.

The primer layer 120 may be deposited on the surface of the injection material 110, and the primer layer 120 may include black pigment to shield light.

The primer layer 120 may be provided by mixing a polished primer and a matte primer. The primer layer 120 may be combined with the colored layer 130, which will be described later, to determine a color. Together with the colored layer 130, the color of the vehicle cover case 100 and luminance in natural light may be satisfied. For this, the mixing ratio of the glossy primer and the matt primer may be provided between 5:5 and 8:2.

의 두께로 증착될 수 있다. 예를 들어 상기 유색층(130)이 10

미만의 두께로 증착되는 경우, 상기 유색층(130)이 쉽게 박리될 수 있고, 상기 유색층(130)이 500

이상의 두께로 증착되는 경우, 무전도의 특성이 저하되어 통전이 발생될 수 있다.The colored layer 130 is 10-500

It can be deposited to the thickness of. For example, the colored layer 130 is 10

When deposited to a thickness less than, the colored layer 130 can be easily peeled off, the colored layer 130 is 500

In the case of depositing with the above thickness, the characteristics of the non-conductivity may be lowered and electricity may be generated.

The colored layer 130 may be deposited by one of thermal heating vacuum deposition, electron beam deposition, thermal deposition, sputtering, and chemical vapor deposition. However, the method of depositing the colored layer 130 of the present invention is not limited to the above method, and any modification or change will be possible as long as it is a method that enables electroless coating.

In addition, when the colored layer 130 is deposited, the brightness of the color and the color of silver may change from gold to gold based on heat conduction, and thus can be implemented in various ways depending on the amount of current and heating time. When indium or tin is used for the colored layer 130, indium or tin has a low melting point and a heavy mass, thereby providing high vacuum and short heat conduction time to realize color and texture.

The hard coating layer 140 may be coated on the colored layer 130 to protect the colored layer 130. The hard coating layer 140 is an eco-friendly solvent-free type, and is transparent and may be deposited to protect the primer layer 120 and the colored layer 130 deposited under the hard coating layer 140. The hard coating layer 140 is an eco-friendly solvent-free type, colorless, odorless, and may be composed of elements having a heavy metal content of less than or equal to international standards.

The hard coating layer 140 may be coated by one of painting, dipping, or spraying.

The hard coating layer 140 is a material having a glossiness, and may affect the color and texture of the colored layer 130. Accordingly, brightness may be determined according to the color and texture of the colored layer 130.

In addition, the hard coating layer 140 may perform a plasma technique to improve bonding with the colored layer 130, that is, adhesion. As the plasma technique is performed, the surface tension may be maximized. The plasma generates a blown ion discharge (concentrated blown-ion discharge) to impact the surface with high-speed discharge of ions. By applying the plasma technique, the organic material and inorganic contaminants may be removed from the surface of the colored layer 130 by applying the ion bombardment of the anode. The plasma technology may have an input frequency of 50-60 Hz, an input current of max 6 per a head, and an output of max 1200 per a head. In addition, the distance from the colored layer 130 may be maintained at 3.5 to 4 cm to prevent deterioration or damage of the colored layer 130.

Figure 5 is a cover case 100 of the vehicle interior and exterior materials (10, 20, 30, 40, 50) according to an embodiment of the present invention, the deposition layers (120, 130, 140) to the outer surface of the case of the transmission A diagram schematically showing the conduction state before and after this treatment. 6 is in the cover case 100 of the vehicle interior and exterior materials (10, 20, 30, 40, 50) according to an embodiment of the present invention, the deposition layer of the surface to the inner surface of the case of the transmission device (120, 130, 140) This is a diagram schematically showing the conduction state before and after treatment. FIG. 7 illustrates whether static electricity is generated in a case in which deposition layers 120, 130, and 140 are treated in a cover case 100 of a vehicle interior and exterior material 10, 20, 30, 40, 50 according to an embodiment of the present invention. It is the figure which started the experiment.

5 to 7, the cover case 100 provided in the interior of the vehicle 1 may be very diverse, but the cover case 100 of the transmission device may be described as an example.

The cover case 100 exposed to the interior surface of the vehicle 1 as an upper surface of the transmission cover case 100 may be injection molded with ABS resin according to the design of the transmission device of the vehicle 1. A primer layer 120 for shielding light with a black pigment may be deposited on the surface of the cover case 100 of the transmission. At this time, the thickness of the deposited layer of the matte primer using urethane for shielding in the primer layer 120 may be implemented to 8 to 10 μm, the drying temperature may be about 80 degrees, and the drying time may be about 10 minutes. In addition, as the primer layer 120, the top of the matte primer can be UV dried to a thickness of about 20±3 μm.

The colored layer 130 may be deposited from an indium or tin material on the top surface of the primer layer 120. The vacuum degree may be 5*10-5, the vacuum time may be about 20 to 30 minutes, the preheating time may be about 17 seconds, and the heating time may be implemented in about 18 seconds.

A hard coating layer 140 may be deposited on the colored layer 130. The hard coating layer 140 may be deposited to a thickness of 3 to 6 μm, the drying temperature may be implemented at about 100±5 degrees, and the drying time may be maintained at about 60 minutes.

As described above, the presence or absence of electric current can be checked in the state deposited on the cover case 100 of the transmission.

For example, as a measurement module for measuring the electrostatic surface voltage in an ionized or non-ionized environment with a non-contact voltmeter such as'ESVM2000', it is possible to check the presence or absence of electrostatic conduction on the cover case 100 of the transmission.

The measurement module is a portable non-contact voltage meter capable of measuring the charging voltage of isolated conductors and non-conductors of ESD international standards, and measuring the static charge of very small objects (eg, the case of a transmission).

The measurement range of the non-contact bolt meter is 0-±2kv DC, and the measurement distance may be 15mm±10mm.

When checking the degree of the electric shock of the human body using the non-contact bolt meter and confirming this, it may be as shown in Table 1 below.

Accordingly, it is possible to detect whether static electricity is generated on the surface of the cover case 100 deposited up to the hard coating layer 140 using the measurement module as shown in FIGS. 5 and 6.

5 and 6, before and after the electroless deposition of tin or indium to the front and rear of the cover case 100, the detection value of the electrostatic voltage measured on the front surface of the cover case 100, and the cover After conducting electroless deposition with tin or indium on the front and rear surfaces of the case 100, it is possible to confirm the detection value of the electrostatic voltage measured on the front surface of the cover case 100. When checking, when comparing the voltage values before and after the non-conductive layer is deposited on the front surface of the cover case 100, the pre-deposition is 1kv, and after the deposition is -2v, static electricity of a level that the human body cannot detect at all is generated. You can confirm that. In addition, when comparing the voltage values before and after the non-conductive deposition to the rear surface of the cover case 100, it can be seen that the deposition is about -7 kv, and after deposition, the degree is insignificant even when static electricity is generated.

In addition, by using the measurement module, it is possible to detect the presence or absence of static electricity in the cover case 100, as well as the stability of the presence or absence of electricity through the cover case according to static electricity generated from the outside, as shown in FIG. 7.

That is, as shown in FIG. 7, as the assembly in which the cover case 100 is coupled through the ESD TEST module, an environment such as static electricity may be applied to the assembly in which the cover case 100 is coupled. Through the ESD TEST module, currents of 2 kv, 4 kv, 8 kv, 18 kv, and 25 kv, which are electrostatic voltages of the IEC standard, can be applied to the cover case 100 to the surface of the cover case 100. In addition, during the ESD test of the cover case, it is possible to test whether or not electricity is applied by applying a current of up to 30 kv. Specifically, the applied voltage of the surface contact can be applied to about ±4kv, ±8kv, and the applied voltage of air discharge can be applied to ±4kv, ±8kv, ±18kv, ±25kv. As a result, it is possible to obtain a result value that satisfies the regulation value for each voltage application. When the current is applied to the cover case 100, the current flowing through the cover case to the internal components of the cover case should be within a range that does not affect the internal components.

In particular, malfunction and breakage of internal components are likely to occur due to application of a voltage of ±8 kv during air discharge. The cover case 100 provided with electroless deposition according to an embodiment of the present invention has a voltage of 8 kv to its surface. Even if this is applied, it is not energized inside, so that the internal components are not affected by the voltage.

Applied voltage Presence of electricity result Remark Surface contact ±4 radish stability The current level applied to the 2 internal components up to 30 kv is a value that does not affect the internal components ±8 radish stability Air discharge ±4 radish stability ±8 radish stability ±18 radish stability ±25 radish stability
