Problems solved by technology

In the field of peeling film, PET is easy to discount in the production process as a release film substrate, the cost is high, and the effect of coating antistatic liquid is poor, and there are phenomena such as silicon falling off or antistatic falling off.
[0004] At the same time, the release film is used in the die-cutting industry and the adhesive field. It is a one-time protective consumable. It cannot be reused after use, so it becomes industrial waste and causes environmental pollution. How to further improve the degradability of the release film performance, making environmentally friendly functional film materials is the key problem to be solved in the film industry at present

Embodiment 1

[0025] Embodiment 1: see figure 1 , the embodiment of the present invention provides a BOPP functional film, which includes a BOPP film layer 1, an adsorption layer 2, an antistatic layer 3 and a release layer 4, the antistatic layer 3, the adsorption layer 2, the BOPP film layer 1 and The release layer 4 is stacked in order from top to bottom; the composition of the BOPP film layer 1 is in parts by weight: 100 parts of polypropylene masterbatch; 15 parts of anti-aging masterbatch; 6 parts of anti-thermal decomposition agent ; 35 parts of solvent; 30 parts of composite polymer; 6 parts of nano-nickel oxide. Preferably, conductive nano-graphene is added to the release layer 4 to achieve anti-static function, which is conducive to better lamination of BOPP functional films, no bubbles, and improved production yield. The composition of the anti-aging masterbatch is 5 parts of antioxidant and 6 parts of anti-ultraviolet agent in parts by weight.

Abstract

The invention discloses a BOPP functional film and a preparation method thereof. The BOPP functional film comprises a BOPP film layer, an adsorption layer, an antistatic layer and a release layer, andthe antistatic layer, the adsorption layer, the BOPP film layer and the release layer are sequentially stacked, or the release layer, the antistatic layer, the adsorption layer and the BOPP film layer are sequentially stacked; the components of the BOPP film layer are scientifically configuring, anti-aging masterbatch can be added, the temperature resistance of the material is improved, the ultraviolet aging degree of the material is alleviated, and the service life of the material is prolonged. Compared with a PET substrate, the cost is lower, the stiffness is lower, the flexibility is stronger, the functional film is more suitable for the high-performance display film material, and the BOPP film layer can be degraded and recycled; the anti-static layer can improve the anti-static performance of the product, eliminate negative impact to the industrial production brought by the electrostatic accumulation, avoids the defects of deformation, folding and improper fitting during the use of the product, is benefit for operation and die cutting, and improves product utilization rate.

Description

technical field [0001] The invention relates to the technical field of functional films, in particular to a BOPP functional film and a preparation method thereof. Background technique [0002] Peeling film, also known as release film, isolation film, separation film, adhesive barrier film, release film, film, plastic film, hole masking film, silicone oil film, silicone oil paper, anti-adhesive film, usually in order to increase the separation of plastic film For molding force, the plastic film will be treated with plasma, or coated with fluorine, or coated with a silicone release agent on the surface of the film material. It can show extremely light and stable release force for various organic pressure-sensitive adhesives (such as hot melt adhesives, acrylic adhesives and rubber-based adhesives). [0003] In the commercial market, BOPP film is often used as a flexible packaging material. BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, ...
