Method of raising wear resistance of base material

Technical Field

The invention relates to a method for increasing wear resistance of base material, in particular to a process for the on the base material needs to be printed, the increase in wear resistance coating method for wear resistance of base material.

Background Art

As semiconductor high-integration of the mature development, to the common use of the mobile telephone. Wherein viewing window panel of the mobile phone not only has the protection of the functions of the mobile phone, more can increase the external appearance of the mobile telephone, in order to improve the consumer to favor. Therefore, mobile telephone manufacturers, not to do what it can to the development of a wear-resistant and with the window panel outer surface of the mobile telephone.

In the case of general mobile telephone message caption display window panel, with the same appearance and a transparent, wear-resistant, the strength requirement, and usually finally also be printed on the window panel surface acting in cooperation with printing of text or graphics. Viewing window panel manufacturing the substrate for multi-is made of plastic material. However, since general plastic material is relatively soft, wear-resistant, unable to reach the required intensity, so usually are required to in order to hardening treatment.

Although physical hardening treatment (such as sputtering Sputtering) also can achieve enhanced hardness, the purpose of the wear [...] , but because the apparatus is expensive, and less the low output rate; for the general consumer electronic product (such as a mobile telephone) of the window panel, its hardening treatment liquid multi-purpose chemical plating film.

General manufacturing viewing window panel of a mobile phone 100 as shown in Figure 1 of the method, the injection molding of a transparent substrate 1, and the base material 1 is arranged in the chemical liquid medicine dip coating, and then, on the substrate 1 to form a hardened layer on the surface of 2 in order to harden its substrate 1 ; then, cleaning the substrate 1, so as to avoid substrate 1 of the chemical remains on the liquid particles impact on the quality of the subsequent process. Finally, surface printing, the hardened layer 2 is formed on a printing layer 3, in order to complete its viewing window panel 100 process. Wherein the printing layer 3 the use of ink will usually dissolve in chemical dip coating of liquid, therefore, form the harden layer 2 chemical dip coating steps, must be in the form a printing layer 3 on the surface of the before the printing step.

However, the above-mentioned traditional process, has the following shortcomings:

1. The surface hardening treatment process for immersion plating, is formed on the window panel to the crystallization point or defects such as dark spots or the like, the beautiful appearance of the viewing window panel affected.

2. The surface hardening treatment process for immersion plating, to on the panel of the window on the small holes, caused by the capillary phenomenon of the liquid immersion plating of signal of the hole is filled, thereby causing panel can't be designed too much restriction of the hole.

3. The surface hardening treatment process for immersion plating, the substrate is etched on the bottom surface of the uneven to form a rainbow-like refraction, dialysis viewing window panel of impact.

4. Printing ink to the dip coated on the hardening substrate, the phenomenon of to smudge an ink, caused by the defects of the FONT generation serrated.

5. Printing ink to the dip coated on the hardened substrate, its adhesion is not good, the phenomenon of a fall off easily.

To sum up, this invention is of the window panel to the traditional shortcomings of the technological process, the method of providing a solution.

Content of the invention

The purpose of this invention is to provide a printed transparency substrate to increase the abrasion resistance of the method.

The invention of the method for increasing the wear resistance of base material, first injection molding a substrate, its material can be a plastic or a PC material, can also be a transparent substrate or a non-transparent substrate. Furthermore, surface printing, a printed layer formed on the base material, finally, use of coating technology, and is the outside of the printing of the substrate, forming a wear-resistant coating, in order to harden the whole substrate. Through the use of this invention with light transmittance and the anti-abrasion coating, to replace the known method uses chemical immersion plating wear-resistant pharmaceutical method, process solve the known problems has been the shortcoming of the method for a long time. To process needs to be printed, and need to be subjected to hardening treatment to [...] transparency abrasion of the substrate, the invention is also the first known chemical dip plating process for hardening before they can be printed on the limit, can also be during the injection molding of the substrate after the step a, first carried out to form the printing layer, and then wear resistant paint coating, the purpose of the device is resistant to wear.

To allow the above-mentioned purposes of this invention, the characteristic and can be more clearly understood, a preferred embodiment for next cultural spy , as detailed as follows.
