Wherein, the bottom surface of the PP synthetic paper layer is also coated with a waterproof isolating layer.

Further, the adhesive layer is an organic silicon pressure-sensitive adhesive layer.

The invention also provides a preparation method of the anti-skid film for the automobile foot mat, which comprises the following preparation steps:

s1, adopting the existing technical means to shape the TPU granules through calendering, tape casting, film blowing and chill roll, then carrying out constant temperature tempering treatment, and longitudinally stretching to obtain a TPU film layer;

s2, coating organic silicon modified epoxy resin on the lower surface of the TPU film layer, and drying;

s3, sequentially placing an organic silicon pressure-sensitive adhesive film and a release film on the lower surface of the TPU film layer coated with the organic silicon modified epoxy resin layer;

s4, carrying out hot pressing on the TPU thin film layer, the organic silicon pressure-sensitive adhesive film and the release film, so that the organic silicon pressure-sensitive adhesive film and the TPU thin film layer are integrally fixed, and the release film and the organic silicon pressure-sensitive adhesive film are fixed in an adhesive manner.

Wherein, in S1, melt coextrusion is carried out at the temperature of 260-280 ℃, constant temperature tempering treatment is carried out at the temperature of 160-170 ℃, and longitudinal stretching is carried out by 4-6 times.

Wherein, after S4, an adhesive layer may be coated on the lower surface of the release film, and the PP synthetic paper may be adhered by the adhesive layer.

The invention has the beneficial effects that: the anti-slip film for the automobile foot mat adopts the TPU film layer and the organic silicon pressure-sensitive adhesive layer, is environment-friendly, free of VOC emission, good in flexibility, ductility and adhesion, and meanwhile, the adhesion enhancement layer is arranged between the TPU film layer and the organic silicon pressure-sensitive adhesive layer, so that residual adhesive is prevented from being torn off after pasting, and the anti-slip film is convenient to tear off. During the use, only need to correspond TPU thin layer and callus on the sole bottom and hug closely, then tear off on one side the type rete on surface press down TPU thin layer and callus on the sole bottom hard, because the TPU thin layer has good pliability and ductility, consequently can laminate with callus on the sole bottom unevenness's position, press the laminating with sticky adhesive layer and car inside at last, make adhesive layer and car bottom laminate, convenient to use has, do not shift, advantages such as environmental protection is tasteless, the non-skid property of callus on the sole and car inside is greatly improved, the callus on the sole can not take place to slide, guarantee that the user can not slide the foot, thereby security and travelling comfort have been improved.

Detailed Description

The present invention will be described in further detail with reference to the following detailed description and accompanying drawings. The present application may be embodied in many different forms and is not limited to the embodiments described in the present embodiment. The following detailed description is provided to facilitate a more thorough understanding of the present disclosure, and the words used to indicate orientation, top, bottom, left, right, etc. are used solely to describe the illustrated structure in connection with the accompanying figures.

Referring to fig. 1, the anti-slip film for the car foot mat of the present invention comprises a high temperature resistant TPU film layer 1, an adhesive layer 3, a release film layer 4 and a synthetic paper layer 5 from top to bottom, wherein the TPU film layer 1 and the adhesive layer 3 are fixed by hot pressing, the release film layer 4 and the adhesive layer 3 are fixed by peeling, and the release film layer 4 is fixed with the synthetic paper layer 5 through an adhesive layer 6; an adhesive force enhancement layer 2 is further arranged between the TPU thin film layer 1 and the adhesive layer 3.

The adhesive force enhancement layer 2 is an organic silicon modified epoxy resin layer, the TPU thin film layer 1 is a high-transparency thin film layer, the release film layer 4 is a high-strength PET release film layer 4, the synthetic paper layer 5 is an imported PP synthetic paper layer 5, and the adhesive layer 3 is an organic silicon pressure-sensitive adhesive layer 3. The user can also spray characters or patterns on the surface of the synthetic paper layer 5 for identification.

The anti-skidding film that this embodiment is used for car callus on sole adopts TPU thin layer 1 and organosilicon pressure sensitive adhesive layer, and the environmental protection does not have VOC and discharges, and pliability, ductility and adhesion are good moreover, set up adhesive force enhancement layer 2 simultaneously between TPU thin layer 1 and organosilicon pressure sensitive adhesive layer, and adhesive force between reinforcing adhesive layer 3 and the TPU thin layer 1 is avoided pasting the back and is torn and stay the cull, is convenient for tear and remove.

In this example, the method of using the non-slip film is as follows: at first to TPU thin layer 1 and callus on the sole bottom correspond hug closely, then tear off the surperficial from the type rete on one side press down TPU thin layer 1 and callus on the sole bottom hard, because TPU thin layer 1 has good pliability and ductility, consequently can laminate with callus on the sole bottom unevenness's position, static laminating still can take place sometimes, make the laminating more firm, press the laminating with sticky adhesive layer 3 and car inside at last, make adhesive layer 3 and car bottom unevenness's position carry out accurate no dead angle laminating, and is convenient to use, do not shift, advantages such as environmental protection is tasteless, the non-skid property of callus on the sole with car inside is improved greatly, the callus on the sole can not take place to slide, guarantee that the user can not slide the foot. When the user wants to change, pull up the callus on the sole upwards with strength, then directly tear with the car in the TPU thin layer 1 of pasting, need not to carry out dust clearance to the inside callus on the sole position of car, better keep the car in clean.

The embodiment also provides a preparation method of the anti-skid film for the automobile foot mat, which comprises the following steps:

s1, adopting the existing technical means to shape the TPU granules through calendering, tape casting, film blowing and chill roll, then carrying out constant temperature tempering treatment, and longitudinally stretching to obtain a TPU film layer 1;

s2, coating organic silicon modified epoxy resin on the lower surface of the TPU film layer 1, and drying;

s3, sequentially placing an organic silicon pressure-sensitive adhesive film and a release film on the surface of the TPU thin film layer 1 coated with the organic silicon modified epoxy resin layer;

s4, carrying out hot pressing on the TPU thin film layer 1, the organic silicon pressure-sensitive adhesive film and the release film, so that the organic silicon pressure-sensitive adhesive film and the TPU thin film layer 1 are integrally fixed, and the release film and the organic silicon pressure-sensitive adhesive film are fixedly adhered;

and S5, coating an adhesive layer 6 on the lower surface of the release film, and bonding the PP synthetic paper through the adhesive layer 6.

In addition, as shown in fig. 2, as another embodiment, on the basis of the above embodiment, a waterproof isolation layer 7 is further coated on the bottom surface of the PP synthetic paper layer 5, for example, a water-tree-resistant cross-linked polyethylene material is coated, so that the overall waterproof and moistureproof effects are achieved, and the product can be better preserved.
