Description

Technical Field

[0001] The utility model relates to the technical field of PE protective films, in particular to a scratch-resistant and wear-resistant PE film. Background Art

[0002] PE polyethylene is a very tough, durable and excellent mechanical property material, which has high scratch and wear resistance itself. And the greater the thickness of the PE protective film, the better its wear resistance usually is. The thicker protective film can better resist scratches, friction and wear, thus prolonging the service life.

[0003] In the prior art, although the PE material has excellent mechanical properties such as high toughness and wear resistance, its tensile strength and impact resistance are relatively weak. Therefore, when the PE protective film is impacted by an external force, the PE protective film may be more likely to deform or break;

[0004] Chinese Patent Publication No. CN220409902U relates to a scratch-resistant and wear-resistant PE film. The technical problem to be solved by the utility model is to provide a scratch-resistant and wear-resistant PE film that can improve the overall wear resistance and scratch resistance, avoid being scratched and worn; and at the same time greatly improve the anti-tensile deformation ability. A scratch-resistant and wear-resistant PE film includes a PE film base layer, a strengthening structure, an outer surface layer, a first wear-resistant layer, a scratch-resistant layer, a second wear-resistant layer, a transverse strengthening strip and a longitudinal strengthening strip. The utility model achieves the effects of improving the overall wear resistance and scratch resistance, avoiding being scratched and worn; and at the same time greatly improving the anti-tensile deformation ability;

[0005] Through the arrangement of the transverse strengthening strip and the longitudinal strengthening strip in the above patent, although the overall anti-tensile property and deformation ability of the PE protective film can be improved, it is difficult to relieve the impact force when being impacted, resulting in a reduction in the protection performance.

[0010] The strengthening structure includes a number of transverse stretching strips and longitudinal stretching strips. Both the transverse stretching strips and the longitudinal stretching strips are arranged in a wavy shape, and the transverse stretching strips and the longitudinal stretching strips are arranged in a cross-woven manner.

[0011] Furthermore, the upper surface layer includes a first wear-resistant layer, a second wear-resistant layer and a puncture-proof layer, and they are, from top to bottom, the first wear-resistant layer, the puncture-proof layer and the second wear-resistant layer.

Specific embodiments

[0025] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0026] Embodiment:

[0027] Refer to Figures 1 - 5 , a scratch-resistant and wear-resistant PE film disclosed by the present utility model includes a PE film base layer 1, a bonding layer 2, a reinforcing structure 3, and an upper surface layer 4;

[0028] The PE film base layer 1 includes a first base layer 101 and a second base layer 102. The first base layer 101 and the second base layer 102 have the same structure, and the top surface of the first base layer 101 and the bottom surface of the second base layer 102 are mutually adhered. The reinforcing structure 3 is arranged between the first base layer 101 and the second base layer 102;

[0029] The reinforcing structure 3 includes a plurality of horizontal stretching strips 301 and vertical stretching strips 302. The horizontal stretching strips 301 and the vertical stretching strips 302 are both arranged in a wavy shape, and the horizontal stretching strips 301 and the vertical stretching strips 302 are cross-woven with each other.

[0030] In this embodiment, the upper surface layer 4 is provided to improve the wear resistance and puncture resistance of the PE protective film on the side facing the outside during use, so as to reduce the risk of sharp objects piercing the protective film;

[0031] The bonding layer 2 enables the PE protective film to be closely adhered to the surface of the object to be protected, so as to solve the problem of the PE protective film falling off;

[0032] Since the PE film base layer 1 is composed of two layers of PE films, it is convenient to wrap the reinforcing structure 3 inside the PE film base layer 1 to improve the impact resistance of the PE film;

[0033] Specifically, since the transverse stretching strips 301 and longitudinal stretching strips 302 which are cross-woven are arranged inside the PE film base layer 1, and both the transverse stretching strips 301 and longitudinal stretching strips 302 are arranged in a wavy shape, when being impacted, they extend to both sides through the elasticity of the stretching strips, thereby achieving the effect of energy absorption and pressure relief, and effectively improving the impact resistance of the PE film.

[0034] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, the upper surface layer 4 includes a first wear-resistant layer 401, a second wear-resistant layer 402 and a puncture-proof layer 403, and from top to bottom are the first wear-resistant layer 401, the puncture-proof layer 403 and the second wear-resistant layer in sequence. The second wear-resistant layer is attached to the upper surface of the second base layer 102.

[0035] In this embodiment, through the first wear-resistant layer 401, the second wear-resistant layer 402 and the puncture-proof layer 403, the wear-resistant and scratch-proof ability and puncture resistance of the plastic film can be improved, avoiding scratches and abrasions of the PE film, and reducing the possibility of the PE film being penetrated.

[0036] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, the bonding layer 2 includes a connecting layer 201 and an adhesive layer 202. The connecting layer 201 is connected to the bottom surface of the first base layer 101, the adhesive layer 202 is arranged on the bottom surface of the connecting layer 201, and a plurality of grooves are formed on the bottom surface of the adhesive layer 202.

[0037] In this embodiment, the connecting layer 201 is provided for connecting the adhesive layer 202 with the PE film base layer 1. Since the adhesive layer 202 has a plurality of grooves, the friction with the object to be protected can be effectively improved, so as to improve the tightness of the film material and the object to be protected.

[0038] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, both the first wear-resistant layer 401 and the second wear-resistant layer are films made of TPU material, and the puncture-proof layer 403 is a film made of nylon material.

[0039] In this embodiment, the TPU film has high wear resistance. In addition, the TPU film also has the characteristics of high strength, high toughness and tear resistance, which can effectively ensure the integrity of the outer surface of the protective film and the wear resistance. The nylon film has good tensile strength, wear resistance and puncture resistance, so the puncture resistance of the PE film can be improved.

[0040] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, both the transverse stretching strips 301 and longitudinal stretching strips 302 are made of elastic plastic material.

[0041] In this embodiment, both the horizontal stretching strip 301 and the vertical stretching strip 302 are made of elastic plastic. Therefore, the stretching strip in a wavy shape can effectively utilize the characteristics of the elastic plastic, and achieve the purpose of absorbing energy and reducing impact force through the deformation of the elastic plastic.

[0042] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
