Decorative film structure with negative ion antibacterial layer

Abstract

This invention is a decorative film structure with a negative ion antibacterial layer, comprising a plastic base body, a surface plastic negative ion antibacterial layer, and an adhesive layer. The top side of the plastic base body is printed with a patterned surface by positive printing or direct coating. The plastic base body and the surface plastic negative ion antibacterial layer are made of the same plastic material. The surface plastic negative ion antibacterial layer is cured and bonded to the patterned surface of the plastic base body. The thickness of the surface plastic negative ion antibacterial layer is the same as the thickness of the plastic base body, and less than or greater than 1 / 2 of the thickness, so that the negative oxygen ion emission and antibacterial properties of the surface plastic negative ion antibacterial layer can be continuous and stable, so as to achieve the effects of long-lasting negative oxygen ion emission and excellent antibacterial effect.

Claims

1. A decorative film structure with a negative ion antibacterial layer, comprising: A plastic base layer has a bonding side and an adhesive side, the top surface of which is positively printed or directly coated with a patterned surface; and a surface plastic negative ion antibacterial layer, which is formed by mixing and curing a number of plastic unit components, a number of porous unit components and a number of negative oxygen ion unit components. The number of plastic unit components covers the number of porous unit components and the number of negative oxygen ion unit components, and the negative oxygen ion unit components are disposed in the pores of the porous unit components. The surface plastic negative ion antibacterial layer and the plastic base layer are made of the same plastic material, and the surface plastic negative ion antibacterial layer is cured and bonded to the top surface of the patterned surface on the bonding side of the plastic base layer.

2. The decorative film structure with a negative ion antibacterial layer as described in claim 1, wherein, The thickness of the surface plastic negative ion antibacterial layer is set to be the same as that of the plastic base layer.

3. The decorative film structure with a negative ion antibacterial layer as described in claim 1, wherein, The thickness of the surface plastic negative ion antibacterial layer is less than or greater than 1 / 2 of the thickness of the plastic base layer.

4. The decorative film structure with a negative ion antibacterial layer as described in any one of claims 1 to 3, wherein, The plastic base layer does not have a patterned printing surface on the bonding side, but has a reverse patterned printing on the inner surface of the surface plastic negative ion antibacterial layer.

5. The decorative film structure with a negative ion antibacterial layer as described in claim 4, wherein, The patterned printing surface on the bonding side of the plastic base layer, or the reverse printing of the patterned printing on the inner surface of the plastic negative ion antibacterial layer, can print wood grain, stone grain, cloth grain or other textures as needed.

6. The decorative film structure with a negative ion antibacterial layer as described in claim 4, wherein, The outer side of the surface plastic negative ion antibacterial layer is provided with a scratch-resistant coating, which is a mixture of fluororesin, polyurethane, acrylic acid, nano alumina or silicon dioxide.

7. The decorative film structure with a negative ion antibacterial layer as described in claim 6, wherein, The plastic base layer and the surface plastic negative ion antibacterial layer are made of three-layer co-extruded sheets of polyvinyl chloride, polypropylene, polyethylene terephthalate, modified polyethylene terephthalate or APET-GAG. The plastic base layer and the surface plastic negative ion antibacterial layer are made of the same material.

8. The decorative film structure with a negative ion antibacterial layer as described in claim 7, wherein, The porous unit components of this surface-plastic negative ion antibacterial layer are selected from a single material or a combination thereof, such as bamboo charcoal powder, diatomaceous earth, quartz powder, ceramic powder, or maifan stone powder.

9. The decorative film structure with a negative ion antibacterial layer as described in claim 8, wherein, The negative oxygen ion unit of this surface plastic negative ion antibacterial layer is selected from a combination of magnesium silicate, magnesium-rich silicate, thorium nitrate crystal and amorphous silicon dioxide.
