Embodiment 1

[0020] A processing method for translucent color PET, printing translucent colored ink on the back of the transparent PET to form a colored ink layer; bonding another layer of transparent PET to the surface of the colored ink layer to form a second transparent PET layer; The surface of the PET layer is silver-plated to form a silver-plated layer; the transparent electroplating protective ink is printed on the surface of the silver-plated layer to obtain such as figure 1 PET in translucent colors shown.

[0021] Wherein, the silver component is Cr; the thickness of the second transparent PET layer is 0.025mm.

[0022] The electroplating protective ink includes the following raw materials in parts by weight: 60 parts of acrylic resin, 10 parts of polyvinyl alcohol, 10 parts of polysiloxane, 1 part of stearamide, 1 part of chitosan, 2 parts of sodium carboxymethyl cellulose 3 parts and 3 parts of antioxidant. The electroplating protective ink is obtained through the following s...

Abstract

The invention discloses a semitransparent color PET processing method, which includes printing translucent color ink on the back surface of transparent PET to form a color ink layer; bonding another layer of the transparent PET on the surface of the color ink layer to form a second transparent PET layer; plating silver on the surface of the second transparent PET layer to form a plated silver layer; and printing transparent electroplating protective ink on the surface of the electroplated silver layer. The processing method realizes color by semitransparent color ink, realizes metal brightnessby electroplating silver, has certain light transmittance, and can avoid oxidation risks; and color ink can be selected according to needs, and thus different semitransparent color PET is obtained.

Description

technical field [0001] The invention relates to a processing method of translucent colored PET, which belongs to the technical field of printing. Background technique [0002] PET plastic is the abbreviation of Polyethylene terephthalate in English, referred to as PET or PETP. Chinese means: Polyterephthalic acid plastics, mainly including polyethylene terephthalate PET and polybutylene terephthalate PBT. Polyethylene terephthalate is also commonly known as polyester resin. It is a condensation polymer of terephthalic acid and ethylene glycol, and together with PBT, it is collectively referred to as thermoplastic polyester, or saturated polyester. [0003] The existing electroplating cannot achieve translucent color PET; and there is a risk of oxidation in the salt spray test. Contents of the invention [0004] In order to overcome the deficiencies of the prior art, the invention provides a processing method for translucent colored PET. [0005] The present invention i...
