CN203007200U - Vent groove car sticker - Google Patents

Abstract

The utility model discloses a vent groove car sticker, wherein the back of a surface film (3) is coated with gum (4) so as to be cohered on a base paper (1), the surface of the base paper (1) comprises a recessed vein groove (2), the gum (4) cohered on the rear side face of the base paper (1) locally extends into the vein groove (2) so as to form the gum vein (5). The surface of the base paper comprises the fine vein groove, after the gum, namely the pressure-sensitive adhesive, is cohered, the cohered layer transfers the vein groove into fine convex gum vein, when pasting the car sticker, the vent groove is formed, the car sticker cannot be rolled up, the car sticker is convenient to cut, convenient for construction and conductive to being flattened when being pasted, when the car sticker is torn down, residual gum cannot be remained, and the car sticker can discharge the construction air bubbles, and is free from wrinkling, crazing and edge warping when being used.

Description

Air vent vehicle body paste

Technical field

The utility model relates to transfer roller cutting device technical field, the especially air vent vehicle body paste in rotary printing.

Background technology

At present, body sticker is used for being attached to the jet drawing material on the carriers such as the mobile media such as vehicle body and external wall, and good, the anti-Japanese illumination aging structure of this type of jet drawing material viscosity comprises the PVC functional layer, three parts of adhesive-layer and lining paper.According to the difference of PVC film production and processing technology, pad pasting can be divided into again casting level pad pasting and a calendering level pad pasting. what domestic production producer mainly adopted is a calendering level PVC pad pasting, and its main characteristic comprises: thick 0.075-0.1mm, can be without transfer paper; Shrinking percentage is larger, and use a middle or short term, is used for plane or small curved surface, and weathering resistance and resistance to chemical corrosion are general.And the world market is mainly take casting level body sticker as main at present, and main manufacturer is with 3M, and AVERY is representative, and domestic manufacturers are is limited to production technology, also can't realize casting the production domesticization of grade body sticker.

Number of patent application 201110310486.5 vehicle sticker for advertisements, formed by substrate layer, pressure-sensitive adhesive layer and PVC thin film layer successively, described substrate layer is separate-type paper, described pressure-sensitive adhesive layer is made of by weight following component: dibutyl phthalate 30-60 part, ethylene-vinyl acetate resin 15-20 part, low-molecular-weight polyisobutylene 5-8 part, terpene resin 10-15 part, phenol formaldehyde resin 1-2 part, sodium lauryl sulphate 0.1-0.3 part, antioxidant BHT 0.1-0.3 part.Vehicle sticker for advertisement of the present invention has advantages of that stripping strength is large.

But, during existing body sticker sticking operation, bubble can often appear, should not eliminate, and in order to reduce bubble pad pasting operation very complicated, when peeling off, the replacing pad pasting is difficult for again removing simultaneously, and residual sticker often appears.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of air vent vehicle body paste, during pad pasting exhaust smooth and easy, realize conveniently pasting and removing.

Realize that goal of the invention measure of the present utility model is: facial mask back side coating gum is bonded on base stock, and there is recessed groove on the base stock surface, and the gum local extension that is fitted in the base stock trailing flank enters groove and consists of the glue line.

The utility model has the advantage of, there is fine and closely woven groove on the base stock surface, at the bonding rear adhesive layer of gum pressure sensitive adhesive, groove is transferred as fine and closely woven protruding glue line, also forms air slot when pasting, guarantee not turnup of product, be convenient to cutting, constructability is beneficial to when pasting smoothly, and does not produce cull when tearing off and leaves over, and not playing fold after discharging construction bubble and use, not alice does not ftracture.

Description of drawings

Fig. 2 is layer structural representation of the present utility model

Reference numeral comprises:

Base stock 1, groove 2, facial mask 3, gum 4, glue line 5.

Embodiment

Further illustrate below in conjunction with embodiment.

As shown in Figure 1, facial mask 3 back sides coatings gums 4 are bonded on base stock 1, and there is recessed groove 2 on base stock 1 surface, and gum 4 local extensions that are fitted in base stock 1 trailing flank enter groove 2 and consist of glue lines 5.

In aforementioned, when facial mask 3 tears off when peeling off, form immediately glue line 5 lines that agree with groove 2 on gum 4, when again pasting on surface of vehicle, the glue line 5 on these gums 4 is just performance air slot effect naturally also, with bubble formation quantity in the operation of minimizing pad pasting.

In aforementioned, groove 2 presents the slit-like air slot, and in the pad pasting operating process, 100% without the Bubble formation puzzlement, and dimensional stability is strong, and the product blotting is stable, and the color rendition degree is high, is applicable to most of dielectric surface, has wide range of applications.

As embodiment, facial mask 3 is 800mircon white light surface and PVC polymeric membrane, and gum 5 is partly can move transparent adhesive tape or pressure sensitive adhesive, and base stock 1 is single face PE, 145gsm.Wide cut is selected 1.06m/1.27m/1.37m/1.52m, and length is selected 50/100m, preservation period 3 years, 3 years usage periods, the scope of application: Weak solvent air brushing, solvent air brushing, cutting, cold mounting, UV ink, the water-based air brushing, silk screen printing, hot transfer printing, and: ads. on vehicle, glass curtain wall advertisement, plane/curved surface advertisement, the display and demonstration picture, business indicates picture etc.

In the utility model, there is fine and closely woven groove 2 on base stock 1 surface, at the bonding rear adhesive layer of gum 5 pressure sensitive adhesives, groove is transferred as fine and closely woven protruding glue line 5, also forms air slot when pasting, and is beneficial to when pasting smoothly, and does not produce cull when tearing off and leaves over.

In the utility model, base stock 1 surface has groove 2 air slots, guarantees not turnup of product, is convenient to cutting, constructability, and discharge the construction bubble and use after do not play fold, not alice does not ftracture.Be beneficial to when pasting smoothly, and do not produce cull when tearing off and leave over.

In above embodiment, do not reach the employing prior aries such as other necessary technologies that relate to enforcement of narration, enumerate no longer successively detailed description.
