Abstract

The utility model aims to provide a silica-gel thin plate which is characterized in that the thin plate bears various patterns painted in different colors which never fade, and is made by combining silica gel with plastic. The silica-gel thin plate provided by the utility model comprises a two-layered or three-layered silica gel layer and a single-layered or two-layered plastic film layer, wherein the plastic film layer is closely stuck in the space between layers of the silica-gel layer, and the surface of the plastic film layer is printed with patterns; and active medium layers are formed on the upper surface and the lower surface of the plastic film layer. The utility model has the following beneficial effects: the silica gel is so closely adhered to the plastic film that the utility model can be prevented from peeling off or delamination; with the different colorful patterns, the silica-gel thin plate has a relatively aesthetic appearance; and the silica gel layer can protect patterns produced with printing ink from shedding or buffing, and stop the patterns from contacting a human body, thereby eliminating the potential hazards of printing ink toxicity.

Description

The silica gel thin sheet that a kind of silica gel and plastics are composited

Technical field

The utility model relates to a kind of silica gel plate, the silica gel thin sheet that particularly a kind of silica gel and plastics are composited.

Background technology

Silica gel has the macromolecular compound characteristic, has the good thermal adaptability of inorganic substances concurrently, and the silica gel goods are widely used in each side such as industry, medical treatment and military affairs at present.

Pellosil or silica gel plate are silica gel goods comparatively commonly used.It is monochromatic or transparent that existing pellosil or silica gel plate are generally, its surperficial pattern adds up by ink for screen printing or pad-transfer printing ink, therefore exist dull coloring, printing ink to expose that easy friction is faded and printing ink easily directly the contact human body cause producing defectives such as poisoning hidden danger.

The utility model content

In order to address the above problem, the purpose of this utility model is to provide a kind of rich color, pattern is various and the silica gel thin sheet that is composited by silica gel and plastics that can not fade.

For this reason, the silica gel thin sheet that the utility model provides a kind of silica gel and plastics to be composited, it comprises layer of silica gel two-layer or three layers, and one deck or two-layer plastic film layers, wherein said plastic film layers fits tightly between layer of silica gel, and at the surface printing of this plastic film layers pattern is arranged.

Upper and lower surface at described plastic film layers all is formed with the activated media layer.

The beneficial effects of the utility model are that silica gel and plastic sheeting can be combined closely, and can not peel off or delamination under certain external force effect; Silica gel thin sheet can realize the various patterns that enrich, outward appearance better appearance; The pattern of ink printing is protected by layer of silica gel, can not come off or grind flower, and can not touch human body, has stopped the hidden danger that printing ink is poisoned.

Description of drawings

The structural representation of first embodiment of the silica gel thin sheet that Fig. 1 is composited for silica gel of the present utility model and plastics;

The structural representation of second embodiment of the silica gel thin sheet that Fig. 2 is composited for silica gel of the present utility model and plastics.

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is elaborated.

The structural representation of first embodiment of the silica gel thin sheet that Fig. 1 is composited for silica gel of the present utility model and plastics.

As shown in the figure, the silica gel thin sheet of the utility model first embodiment is a three-decker, comprises two-layer layer of silica gel 1 and layer of plastic film layer 3, and this plastic film layers 3 fits tightly between two-layer layer of silica gel 1.Wherein, plastic film layers 3 will have extremely strong adhesive force through after the surface activation process at its surface printing printing ink.Plastic film layers 3 is made with the material of high temperature resistant and environmental protection, and can go out coloury various pattern at the surface printing of plastic film layers 3 by methods such as ink for screen printing or pad-transfer printing inks.

Subsequently, printing surface and the non-printing surface at plastic film layers 3 is coated with activated media layer 2.The silica gel raw material is pressed into layer of silica gel 1, through overcompaction, row's bubble, and the operation of process hot setting closely and securely is bonded as one with the plastic film layers 3 that is coated with activated media layer 2, the silica gel thin sheet of formation three-decker.Wherein, be transparent with the bonding layer of silica gel 1 in the figuratum surface of the printing of plastic film layers 3 at least, so that represent the pattern of layer of silica gel 1 protection that is subjected to this layer Transparent color.

As shown in the figure, the silica gel thin sheet of second embodiment is a five-layer structure, comprises three layers of layer of silica gel 1 and two layers of plastic thin films layer 3, and these two layers of plastic thin films layer 3 difference close adhesion are between every two-layer layer of silica gel 1.Wherein, surperficial with the plastic film layers 3 that the material of high temperature resistant and environmental protection is made through after the activation processing, can go out the extremely strong coloury various patterns of adhesive force at the surface printing of plastic film layers 3 by methods such as ink for screen printing or pad-transfer printing inks.

Subsequently, printing surface and the non-printing surface at plastic film layers 3 is coated with activated media layer 2.The silica gel raw material is pressed into layer of silica gel 1, through overcompaction, row's bubble, and the operation of process hot setting closely and securely is bonded as one with the plastic film layers 3 that is coated with activated media layer 2, the silica gel thin sheet of formation five-layer structure.

The difference of above-mentioned second embodiment and first embodiment is; middle one deck of three layers of layer of silica gel 1 is opaque; the layer of silica gel of top layer and bottom is transparent; simultaneously two layers of plastic thin films layer 3 has pattern at the bonding surface printing of itself and the layer of silica gel 1 of top layer and bottom respectively, makes silica gel thin sheet of the present utility model two sides all can represent to be subjected to pattern that layer of silica gel 1 is protected and the effect that is independent of each other to reach.

The silica gel thin sheet of making through above-mentioned operation of the present utility model can have various rich colors pattern handsome in appearance; and because the figuratum plastic film layers of printing is protected by layer of silica gel; thereby pattern can not come off and fade or wear and tear, and has avoided the contact human body and the hidden danger that causes poisoning.Plastic film layers and layer of silica gel can be combined closely simultaneously, can not peel off or delamination under certain external force effect.
