The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.

As shown in Figure 1, the preferred embodiment of the manufacturing approach of silica gel lines transfer membrane of the present invention is to use solid-state silica gel to make the lines transfer membrane, and it comprises the following step:

Step 1: prepare a surface and have the lines drip molding 10 of lines and prepare a solid-state silica gel sheet 20.This lines drip molding 10 is surperficial steel plate with lines, and the forming mode of lines is etching or electrotyping process; This lines drip molding 10 also can be the leather goods with lines, and this leather goods with lines is natural leather or artificial synthetic skin [the synthetic skin of for example processing with thermoplastic polyurethane elastomer (TPU), response type thermoplastic polyurethane elastomer (response type TPU), polyurethanes (PU), polyvinyl chloride materials such as (PVC)].

Step 2: this silica gel sheet 20 is placed on this lines drip molding 10, and utilize 100 pairs of these silica gel sheets of a hot press 20 and this lines drip molding 10 to carry out hot pressing, make these silica gel sheet 20 sclerosis and accomplish cross-linking reaction, hot pressing temperature is 140 ℃～200 ℃.

Step 3: on this silica gel sheet 20, lay a silica gel rete 30, this silica gel rete 30 contains crosslinking agent, can be solid-state silica gel thin film, or is formed with the liquid-state silicon gel wiper.

Step 4: cooperate and consult Fig. 2, on this silica gel rete 30, paste a basic unit 40, this basic unit 40 is a yarn fabric, and this basic unit 40, this silica gel rete 30, this silica gel sheet 20 are folded by last with this lines drip molding 10 down layer by layer mutually.

Step 5: this basic unit 40 to after fitting heats with this silica gel rete 30, this silica gel sheet 20, this lines drip molding 10, borrows this silica gel rete 30 to make this basic unit 40 and this silica gel sheet 20 produce fixed.

When this silica gel rete 30 when being solid-state; Can utilize this basic unit 40 after 200 pairs of applyings of a continuous hot-press make-up machine to carry out heat pressing operation with this silica gel rete 30, this silica gel sheet 20, this lines drip molding 10; Borrow this silica gel rete 30 to make this basic unit 40 and this silica gel sheet 20 produce fixed; This silica gel rete 30 links with this basic unit 40, and is integral (see figure 3) with these silica gel sheet 20 clinkerings.This continuous hot-press make-up machine 200 has a patrix 210 and ability counterdie 220 with respect to these patrix 210 closings or separation.

When this silica gel rete 30 was formed by the liquid-state silicon gel wiper, this continuous hot-press make-up machine 200 replaced with an oven dry baking box (figure does not show), and this basic unit 40 after fitting is heated with this silica gel rete 30, this silica gel sheet 20, this lines drip molding 10.

Step 6: cooperate and consult Fig. 4, tear off this lines drip molding 10, can obtain a silica gel lines transfer membrane 50 with lines.

The silica gel lines transfer membrane 50 that makes through above-mentioned steps; Comprise this basic unit 40 and this silica gel sheet 20; These silica gel sheet 20 surfaces are shifted dermatoglyph through this lines drip molding 10 and are formed with lines; And this silica gel lines transfer membrane 50 also can be used to impress out lines as a mould that is used to produce lines when other processing procedure.

Effect of the present invention is following:

1. the lines that itself possesses through this lines drip molding 10; Not only do not need to impress out lines through the involutory cutification of the runner with lines like existing synthetic skin; And the making of this lines drip molding 10, obtain quite easily, can reuse, can reduce cost of manufacture.

2. the lines that utilizes this lines drip molding 10 itself to possess shifts on the surface of this silica gel sheet 20 and is formed with lines, and the lines transfer effect is also preferable.

3. What is worth mentioning is, if this lines drip molding 10 is a natural leather, it scribes the process of runner through taking pictures, transplanting, and natural lines is to be difficult to true reduction, can truly lines reprinted out through the present invention.
