Problems solved by technology

[0002] In the prior art, the processing of metal blanks not only involves the processing area, but because the processing area and the non-processing area cannot be effectively separated during the production process, the metal surface of the non-processing area is often irradiated, resulting in some undesirable non-processing areas. Some accidental damage to the surface of the area

Embodiment 1

[0018] The metal blank protective film is composed of a bottom layer 4, an elastic layer 3 and an impact-resistant layer 1 in sequence, the bottom layer is a nano-silver layer, and the impact-resistant layer is a sapphire layer.

[0019] Further, the sapphire layer adopts a sapphire sheet with a thickness of 0.1-0.2 mm.

[0020] Further, the elastic layer includes butyl rubber, natural rubber or synthetic rubber, EPDM, VAMAC, NBR, silicone rubber, SBR, polypropylene+EPDM, and any combination thereof.

[0021] Further, a zirconia layer 2 is provided between the sapphire layer and the elastic layer; a zirconia layer 2 is provided between the elastic layer and the bottom layer.

[0022] Further, the elastic layer includes a first elastic layer 31 and a second elastic layer 32, the first elastic layer is formed by connecting a plurality of uniformly arranged arcuate elastic cavities; the second elastic layer is formed by It is formed by connecting multiple uniformly arranged bow-...

Embodiment 2

[0029] The metal blank protective film in this embodiment is consistent with the structure of Embodiment 1, the difference is that the surface of the sapphire layer in this embodiment is provided with a scratch-resistant coating, and the coating is composed of the following parts by weight Composition: 32 parts of epoxy modified silicone resin, 12 parts of EPDM rubber, 12 parts of fish scale powder, 5 parts of polyvinylpyrrolidone, 5 parts of C18 powder, 7 parts of aminosiloxane, 5 parts of hydroxyethyl cellulose , 16 parts of polypropylene alcohol.

[0030] The anti-scratch coating provided by the invention not only has good wear-resistant and anti-scratch performance, but also has fast curing speed, stable performance, strong weather resistance, and can protect the metal shell for a long time.

Embodiment 3

[0032] The metal blank protective film in this embodiment is consistent with the structure of Embodiment 1, the difference is that the surface of the sapphire layer in this embodiment is provided with a scratch-resistant coating, and the coating is composed of the following parts by weight Composition: 49 parts of epoxy modified silicone resin, 22 parts of EPDM rubber, 18 parts of fish scale powder, 12 parts of polyvinylpyrrolidone, 9 parts of C18 powder, 12 parts of aminosiloxane, 10 parts of hydroxyethyl cellulose Parts, 25 parts of polypropylene alcohol.

[0033] The anti-scratch coating provided by the invention not only has good wear-resistant and anti-scratch performance, but also has fast curing speed, stable performance, strong weather resistance, and can protect the metal shell for a long time.

Abstract

The invention provides a metal blank protective film. The protective film provided by the invention is arranged on a non-machining region of a metal blank, so that injuries, caused by machined workpieces, to the non-machining region can be effectively avoided; and the protective film can be applied to a utilization process of a formed metal product, a subsequent procedure of sticking a film is reduced, and a production procedure is simplified.

Description

technical field [0001] The invention specifically relates to a protective film for metal blanks. Background technique [0002] In the prior art, the processing of metal blanks not only involves the processing area, but because the processing area and the non-processing area cannot be effectively separated during the production process, the metal surface of the non-processing area is often irradiated, resulting in some undesirable non-processing areas. The surface of the area has some accidental damage. Therefore, there is an urgent need for a metal blank protective film, which can be arranged in a non-processing area and can be applied to the use of the final product. Contents of the invention [0003] In view of this, the present invention provides a protective film for metal blanks. The protective film of the present invention is placed on the non-processing area of ​​the metal blank, which can effectively avoid the damage of the workpiece to the non-processing area, an...
