Problems solved by technology

If the adhesive layer of the decorative film is not fully unfolded and flattened when it is attached, it will be prone to self-bonding and wrinkling due to stickiness, or problems such as inclination and deviation due to corresponding position problems after attachment, all need Re-lifting and re-attaching the corners of the attached place will affect the viscosity of the adhesive layer, and the decorative film at the corners is not easy to lift due to the stickiness

Embodiment Construction

[0026] The present invention will be further elaborated below by means of the accompanying drawings and examples.

[0027] like Figure 1-4 Shown: a PVC water-based antibacterial decorative film, including a PVC decorative film body 1, the adhesive side of the PVC decorative film body 1 is sprayed with a backing layer 2, the bottom of the backing layer 2 is adhered to a backing paper 3, and the backing layer 2 and There is a slow-adhesive structure between the backing paper 3, and the slow-stick structure is located at the corners of the four sides of the PVC decorative film body 1, so as to replace the adhesive layer 2 and the place to be bonded in advance. Layer 2 can be bonded again with the place to be bonded under external force.

[0028] See attached figure 2 As shown, the slow-adhesive structure is a micro-protrusion 4, and the micro-protrusion 4 is connected to the PVC decorative film body 1 in a hot-melt manner, and its outer end protrudes to the outside of the adh...

Abstract

The invention discloses a PVC water-based antibacterial decorative film and a post-treatment preparation device thereof. The PVC water-based antibacterial decorative film comprises a PVC decorative film body, wherein a back gum layer is sprayed to the attaching side of the PVC decorative film body, backing paper adheres to the bottom of the back gum layer, slow adhesion structures are arranged between the back gum layer and the backing paper and located at the corners of the four side portions of the PVC decorative film body so as to replace the back gum layer to pre-contact a to-be-adhered position, and the back gum layer at the corner position can be bonded with the to-be-adhered position again under the external acting force. According to the invention, the slow adhesion structures are arranged at the four corners of the back gum layer, so that when the PVC decorative film body needs to be attached again due to deviation in attachment, the viscosity of the corners of the back gum layer is not affected by repeated attachment; and the post-treatment device for slow adhesion structure mounting preparation is arranged, so that matched industrial production is realized.

Description

technical field [0001] The invention relates to a PVC water-based antibacterial decorative film and a post-processing preparation device thereof. Background technique [0002] Decorative film is a kind of PVC water-based antibacterial decorative film made by adding various additives, calendering and compounding with high molecular polymer PVC as raw material and a new decorative material for its post-processing preparation device. It can be used with wood, plastic board, Aluminum plate, iron plate and other substrates are composited into multi-purpose decorative materials, which are widely used in household appliances, audio surface decoration, interior decoration, interior decoration of aircraft, ships and trains. In addition, it can also be used for billboards, etc. If the adhesive layer of the decorative film is not fully unfolded and flattened when it is attached, it will be prone to self-bonding and wrinkling due to stickiness, or problems such as inclination and devia...
