Description

Release pressure-sensitive adhesive tape for automobile word plate

Technical Field

Belongs to the field of automobile word plates, and relates to a protective film, in particular to a film substrate single-sided pressure-sensitive adhesive tape with CCK paper as a release layer.

Background

In the field of automobile word plate protective films, a qualified protective film not only protects the surface of a word plate to prevent scratches or stains, but also has a series of functional requirements for realizing efficient installation by matching with a word plate assembly (release paper for word plate back glue, a word plate and a protective film), for example, the relative positions of all parts (letters, numbers, Chinese characters, figures and the like) of the word plate are fixed, and a seal can be arranged on the release paper.

Particularly, for the requirement of a seal, the PEK paper coated with PE plastic is selected as a release material for a common protective film, the influence of the paper on the humidity is small, and a finished product is flat and has no warpage. However, because the surface of the PEK paper is provided with the PE laminating film, the printing ink can not be attached, and the requirement of the seal can not be met.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's weak point, provide an use CCK paper for the film substrate single face pressure sensitive adhesive tape from the type layer, except possessing the characteristics that general protection film had, still satisfied the requirement at the seal on type paper.

The utility model provides a technical scheme that technical problem adopted is:

the utility model provides an automobile word tablet is with leaving type pressure sensitive adhesive tape, is from type paper layer, pressure sensitive adhesive layer and film substrate layer including the CCK of laminating in proper order, CCK is from type paper layer for single face kaolin coating silicon-coated from type paper, CCK is from type paper layer thickness and is 0.08 ~ 0.2 mm.

Furthermore, the thickness of the CCK release paper layer is 0.1-0.15 mm.

Further, the pressure-sensitive adhesive layer is a rubber pressure-sensitive adhesive or an acrylic pressure-sensitive adhesive. The thickness is 0.02-0.03 mm.

Further, the film substrate layer is a PP film, a PET film or a PVC film. The thickness is 0.05-0.3 mm.

The utility model has the advantages that:

the utility model discloses a CCK is as from type paper, and the non-requirement that can satisfy the seal from the type face. The moisture content of the CCK paper is balanced by matching with a humidifying device, and the problem that the CCK is easy to warp is solved. The protective film adhesive tape with the CCK paper as the release layer is realized.

Detailed Description

The present invention will be described in further detail with reference to specific examples, which are provided for illustrative purposes only, and are not intended to be limiting, and the scope of the present invention should not be limited thereby.

As shown in figure 1, the utility model discloses car word tablet is with leaving type pressure sensitive adhesive tape is including the CCK who laminates in proper order from type paper layer 1, pressure sensitive adhesive layer 2 and film substrate layer 3.

The CCK release paper layer 1 is single-sided kaolin coated silicon-coated release paper, a mixture coating of kaolin, polyvinyl alcohol and latex is coated on the surface of base paper to replace PE (polyethylene) laminating of PEK (polyethylene glycol) paper, so that the feasibility of recycling the paper is improved while the water absorption of the paper is reduced, and the appearance texture (stiffness and glossiness) of the CCK release paper layer is superior to that of the PEK paper; and finally, coating silicone oil on the kaolin coating to realize release, wherein the coating is oil-resistant, and the coated silicone oil is flat and uniform, so that the CCK release paper has small release force fluctuation range and excellent quality. The thickness is 0.08 to 0.2mm, preferably 0.1 to 0.15 mm. The gram weight is 80-200 g/m²The weight is too low, the paper stiffness is not enough, the texture is poor, and the assembly process of the large and heavy character label is influenced. The weight is too high, the release paper is hard, the influence on the rewinding processing in the later period of the adhesive tape is large, and the conditions of bending and folding are easy to occur. The gram weight is preferably 100-130 g/m²The release force is in the range of 0.002-0.3N/25 mm, preferably 0.005-0.25N/25 mm.

The pressure-sensitive adhesive layer 2 can be rubber pressure-sensitive adhesive and acrylic pressure-sensitive adhesive, and the thickness of the adhesive is 0.005-0.05 mm. Preferably 0.01-0.03 mm. More preferably 0.02 to 0.03 mm. The gluing thickness influences the bonding force on the word plate, and then can be used for balancing the requirements on two aspects of bonding and residual glue, and through long-term practice, the thickness range of 0.02-0.03 can well meet the requirements of most word plate types.

The film substrate layer 3 can be a PP film, a PET film or a PVC film, and the thickness is 0.05-0.3 mm.

The utility model discloses car word tablet is with release pressure sensitive adhesive tape's preparation method does:

firstly, coating a pressure-sensitive adhesive layer 2 on a CCK release paper layer 1, drying, attaching the film base material layer 3 subjected to plasma treatment, and coiling the film base material layer after passing through humidifying equipment.

The utility model discloses car word tablet is with from type pressure sensitive adhesive tape's application method does:

as shown in fig. 2, the film substrate layer 3 is adhered to the surface of the automobile word plate 4 through the pressure sensitive adhesive layer 2, the CCK release paper layer 1 is adhered to the back adhesive surface of the automobile word plate 4, and a seal can be formed on the non-release surface of the CCK release paper layer 1.

The utility model discloses break through car word tablet with the tradition from type pressure sensitive adhesive tape from type paper selection type, select CCK to do from the type material, combine humidification treatment, the result of use is the same with PEK paper, it is flat and to have the stick up to expand the sticky tape, satisfies the requirement that can the seal simultaneously. As shown in fig. 4.

In the present invention, unless otherwise specified, the term "protective film" is not limited to a tape shape, but includes a sheet shape, and any other shape compatible with the application.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the spirit of the present invention, and these modifications and improvements are all within the protection scope of the present invention.
