High-stripping laminating PVC film

Technical Field

The utility model belongs to the technical field of PVC films, and particularly relates to a high-stripping laminating PVC film.

Background

PVC is mainly composed of polyvinyl chloride, is yellowish semitransparent and glossy. The transparency is superior to polyethylene and polypropylene, is inferior to polystyrene, and is divided into soft and hard polyvinyl chloride according to the different dosage of the auxiliary agent, the soft product is soft and tough, the hand feeling is sticky, the hardness of the hard product is higher than that of the low density polyethylene, and the hard product is lower than that of the polypropylene, and the whitening phenomenon can occur at the bending position. Common articles: plate, pipe, sole, toy, door and window, wire sheath, stationery, etc.

The PVC film is a transparent membranous structure made of polyvinyl chloride, and is usually stuck on an article to protect the article, and the material with low peeling strength is easy to generate layering phenomenon in the use process, so that the service life of the protected article is shortened.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides the glass fiber which can be effectively integrated into the functional layer by arranging the glass fiber between two adjacent layers so as to form an effective drawing effect on the two adjacent layers, thereby preventing layering phenomenon, improving the protective capability and prolonging the service life of the protected article.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a high laminating PVC membrane that peels off, includes the PVC basic unit, is provided with the adhesive linkage in PVC basic unit below, PVC basic unit top is provided with the wearing layer, all is provided with glass fiber between arbitrary adjacent two-layer.

Further the glass fibers extend from the bonding layer to the wear layer.

Further, the upper end and the lower end of the glass fiber are bent to form a tensile elbow.

And a pattern layer is further arranged between the wear-resistant layer and the PVC base layer.

Further, the surface of the glass fiber is provided with burrs.

Compared with the prior art, the utility model has the beneficial effects that: through setting up glass fiber, it can be taut with arbitrary adjacent two-layer, prevents that layering phenomenon from appearing in arbitrary adjacent two-layer, can prevent that glass fiber from being taken out through setting up tensile elbow simultaneously, prevents that glass fiber from directly deviating from by arbitrary functional layer promptly, strengthens the intensity between its taut functional layer to realize that whole PVC membrane has high peeling off function.

Detailed Description

Further description of embodiments of the high peel adhesion PVC film of the present utility model is provided with reference to fig. 1 and 2.

In the description of the present utility model, it should be noted that, for the azimuth words such as the terms "center", "transverse (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the azimuth and positional relationships are based on the azimuth or positional relationships shown in the drawings, only for convenience of describing the present utility model and simplifying the description, but do not indicate or imply that the apparatus or element to be referred to must have a specific azimuth, be constructed and operated in a specific azimuth, and should not be construed as limiting the specific protection scope of the present utility model.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features. Thus, the definition of "a first", "a second" feature may explicitly or implicitly include one or more of such feature, and in the description of the present utility model, the meaning of "a number", "a number" is two or more, unless otherwise specifically defined.

As shown in fig. 1:

the utility model provides a high laminating PVC membrane that peels off, includes PVC basic unit 2, is provided with adhesive layer 1 in PVC basic unit 2 below, PVC basic unit 2 top is provided with wearing layer 4, all is provided with glass fiber 6 between the arbitrary adjacent two-layer.

In this embodiment, the release paper 5 is provided on the lower surface of the adhesive layer 1, and the glass fibers 6 do not extend onto the release paper 5, and in use, the release paper 5 is peeled off directly, and the whole PVC film is adhered to the article through the adhesive layer 1.

In this embodiment, the glass fiber 6 is only connected with any two adjacent layers, namely, the PVC base layer 2 and the adhesive layer 1, and the PVC base layer 2 and the wear-resistant layer 4, at this time, the glass fiber 6 is shorter in length, two ends of the glass fiber are respectively embedded and fused into the two adjacent layers, so as to achieve the purpose of further connecting and reinforcing the connection strength of the two adjacent layers, and the whole of the glass fiber 6 is preferably perpendicular to the surface of each layer.

A pattern layer 3 is preferably arranged between the wear-resistant layer 4 and the PVC base layer 2 in this embodiment.

The pattern layer 3 can be set according to the pattern style actually required, and when the pattern layer 3 is provided, the glass fiber 6 connects the PVC base layer 2 and the adhesive layer 1, the PVC base layer 2 and the pattern layer 3, and the pattern layer 3 and the wear-resistant layer 4.

The surface of the glass fiber 6 preferably has burrs Mao Cineng, which can enhance the connection strength between the glass fiber 6 and the functional layer, that is, the glass fiber 6 can be better embedded and connected and fixed with the adhesive layer 1, the PVC base layer 2, the pattern layer 3 and the wear-resistant layer 4.

Embodiment two:

the glass fibers 6, which are preferred in this embodiment as shown in fig. 2, extend from the adhesive layer 1 to the wear layer 4, the remaining technical features being the same as in the first embodiment.

That is, in this embodiment, the entire PVC film has only one long glass fiber 6 in the thickness direction, which connects the outermost two layers from top to bottom.

The upper and lower ends of the glass fiber 6 are bent to form a tension elbow 61.

The tensile bend 61 can enhance the strength of the connection between the end of the glass fiber 6 and the wear layer 4 and the adhesive layer 1, and enhance the resistance when the glass fiber 6 is pulled out, thereby avoiding the pulling out.
