Printed organic silicone synthetic leather and preparation method thereof

Abstract

The invention discloses printed organic silicone synthetic leather and a preparation method thereof. The printed organic silicone synthetic leather comprises a silica gel layer (4), an ink layer (3), a colored silica gel layer (2) and a base material (1) in sequence from top to bottom. The preparation method includes the steps that blended silica gel layer adhesive is arranged on release paper or a release film in a coated mode and vulcanized to form the silica gel layer (4), blended ink layer adhesive is utilized to form a printed pattern on the cured silica gel layer (4) in a spraying or coating mode, blended colored silica gel layer adhesive is arranged on the vulcanized ink layer (3) in a coated mode to be attached to the base material (1), after vulcanization is conducted, the release paper or the release film is stripped, and the printed organic silicone synthetic leather is obtained. According to the printed organic silicone synthetic leather and the preparation method thereof, the release film or the release paper is utilized to cover the silica gel ink layer with a transparent layer, so that a bonding layer and a surface protection layer are additionally arranged on silica gel ink, it is difficult to remove the printed pattern from the organic silicone synthetic leather, diversity can be achieved, and the layered feeling is obvious.

Description

technical field [0001] The invention relates to a printed organic silicon synthetic leather by inkjet code printing and a preparation method thereof, which belongs to the technical field of organic silicon synthetic leather. Background technique [0002] At present, synthetic leather is mostly made of surface layers such as TPU, PU, ​​PVC, etc. However, the physical and chemical properties of these materials such as antifouling, air permeability, high and low temperature resistance, hydrolysis resistance, and aging resistance are not ideal, and these The raw materials used to make materials are harmful to the environment, and harmful substances will also be produced when waste products are incinerated. Silicone synthetic leather can solve these problems. However, because the silicone is difficult to bond after vulcanization, the ink is difficult to print on the leather, resulting in a single color of the silicone leather.

Problems solved by technology

[0002] At present, synthetic leather is mostly made of surface layers such as TPU, PU, ​​PVC, etc. However, the physical and chemical properties of these materials such as antifouling, air permeability, high and low temperature resistance, hydrolysis resistance, and aging resistance are not ideal, and these The raw materials used to make materials are harmful to the environment, and harmful substances will also be produced when waste products are incinerated.

Silicone synthetic leather can solve these problems. However, due to the difficulty of bonding silicone after vulcanization, it is difficult to print ink on the leather, resulting in a single color of silicone leather.
