Description

Crystal adhesive

Technical field

The utility model belongs to the field of adhesive, and is specifically a crystal adhesive.

Background technique

Conventional adhesive refers to stamp adhesive, outdoor advertising adhesive, photo adhesive, transparent adhesive, body printing adhesive; and industrial adhesive refers to leather backing, PU leather backing, cardboard adhesive; The gift box factory's flannel backing and satin backing; the shoe factory's non-woven backing, twill backing, sponge backing, EVA adhesive, extending the traditional adhesive way to the industrial adhesive industry, application Wide range, easy to use, saving manpower and material cost, forming a professional adhesive rubber industry.

At present, the traditional PP backing on the market is directly coated with a swellable coating on PP paper, and then coated with a PET release film after back coating with a self-adhesive, and used with a cold laminating film, cold laminating film. The most common structure is the combination of PVC and release paper. The customer prints the picture on the PP backing, and then tears off the cold-coated film. Using PVC fabric and self-adhesive with PP adhesive. The film protects the picture. The drawback of this product is that both PP paper and PVC are not stiff enough, and the feel is too soft after the film is removed. Moreover, PP is easily deformed due to insufficient heat resistance at the time of coating, and the coating speed is limited in order to keep the product flat and only reduce the temperature production.

Summary of the invention

The purpose of the utility model is to provide a crystal backing glue with high glossiness, high cost performance, stiff product, long service life and wide adaptability.

In order to achieve the above object, the utility model adopts the following technical solutions:

A crystal backing comprising a first portion and an intermediate portion, the first portion comprising an inkjet layer and a substrate layer, a lower surface of the inkjet layer conforming to an upper surface of the substrate layer, the second portion The first PET release layer, the first adhesive layer, the PP pearl film, the second adhesive layer, and the second PET release layer are sequentially stacked from top to bottom, and the first PET release layer is The lower surface is adhered to the upper surface of the first adhesive layer, the lower surface of the first adhesive layer is bonded to the upper surface of the PP bead film, and the lower surface of the PP bead film and the second sticker are The upper surface of the layer is bonded, and the lower surface of the second adhesive layer is bonded to the upper surface of the second PET release layer.

Further, the substrate layer is a PET transparent substrate.

Further, the substrate layer has a thickness of 36 to 50 μm.

The PET transparent substrate not only acts as a substrate, but also acts as a protective film in later use, protecting the picture from being scratched in the inner layer and not being affected by the humidity of the outside air.

Further, the inkjet layer is a swellable coating.

Further, the ink-jet layer has a thickness of 10 to 14 μm.

Further, the first PET release layer and the second PET release layer each have a thickness of 10 to 14 micrometers.

The first PET release layer and the second PET release layer are coated with a layer of silicone oil on the transparent PET, and the thickness of the silicone oil is substantially negligible.

Further, the first self-adhesive layer and the second self-adhesive layer are both aqueous acrylic pressure sensitive adhesives.

Further, the first self-adhesive layer and the second self-adhesive layer have a thickness of 10 to 12 micrometers.

Further, the PP pearl film has a thickness of 40 to 140 μm.

The first part and the second part of the crystal backing are used together. In use, the mirror image is first printed on the first part of the inkjet layer with dye ink, and then the second part of the first PET release layer or the second PET release is removed. Layer, the printed first part is reversely attached to the first part of the second self-adhesive layer or the second self-adhesive layer, flattened, the product presents a vivid color, and then according to the placement position of the advertisement, the second Part of the second PET release layer or the first PET release layer is torn off, and the second self-adhesive layer or the first self-adhesive layer is adhered to the medium, and the medium may be a KT foam plate, a glass plate, an acrylic plate. Wait.

The utility model has the following beneficial effects:

First, the gloss is high. Due to the good transparency of PET, the water-based pressure-sensitive adhesive used is transparent after drying. After the use, the gloss and flatness of the whole product are particularly good, giving customers a high-end feeling.

Second, cost-effective. Due to the coating on PET, PET has good heat resistance, can raise the temperature and increase the speed, and improve the production efficiency.

Third: The product is stiff. Since the PET is relatively stiff, the water-based rubber backing after the completion is firm and the display effect is better and longer.

Fourth, long service life. The inkjet layer is bonded with the self-adhesive layer by means of bonding, which effectively ensures the bonding effect of the inkjet and the inkjet layer, ensures the stability of the crystal backing structure, and prolongs the service life of the crystal backing.

Fifth, the scope of use is wide. Since the image is printed in reverse, the screen is effectively protected, so that the screen is not scratched or contaminated, and can be used for a long time. It can be used indoors and outdoors, and can be used for display racks, KT boards, posters, glass stickers, and acrylic sheets.

In summary, the crystal adhesive of the utility model has the characteristics of high gloss, high cost performance, excellent quality consistency, long service life and wide application range.
