Embodiment Construction

[0024] In order to understand the technical scheme of the present invention more intuitively and completely, the non-limiting feature descriptions are as follows in conjunction with the accompanying drawings of the present invention:

[0025] Such as figure 1 As shown, the antistatic pre-coating film includes a hydrophobic and oil-repellent layer 1, a base layer 2, a primer layer 3 and a hot-melt adhesive layer 4 arranged sequentially from the outside to the inside;

[0026] The hydrophobic and oil-repellent layer 1 is a three-layer structure, which includes a nano-silicon dioxide layer 11, a fluorosilane layer 12, and a protective layer 13 composed of aminoacrylic resin, xylene and nano-silicon dioxide arranged sequentially from the outside to the inside;

[0027] Base layer 2 is composed of polypropylene, ethoxylated alkylamine and ethoxylated lauric amine;

[0028] Primer layer 3 is made up of polyethyleneimine aqueous solution and alcohol;

[0029] The hot melt adhesive ...

Abstract

The invention discloses an antistatic pre-coating film and a production method thereof. The antistatic pre-coating film comprises a hydrophobic and oleophobic layer, a base layer, a bottom coating agent layer and a hot melt adhesive layer which are sequentially arranged from outside to inside, wherein the hydrophobic and oleophobic layer is of a three-layer structure and comprises a nano-silicon dioxide layer, a fluorosilane layer and a protective layer which are sequentially arranged from outside to inside, the protective layer is composed of an amino acrylic resin, xylene and nano-silicon dioxide, the base layer is prepared from polypropylene, ethoxylated alkylamine and ethoxylauric acid amine, the bottom coating layer is composed of a polyethyleneimine aqueous solution and alcohol, andthe hot melt adhesive layer is composed of an ethylene-vinyl acetate copolymer and vinyl acetate. The bonding strength of the base layer and the hot melt adhesive layer is high, and the pre-coating film has various functions.

Description

technical field [0001] The invention relates to the technical field of precoating film, in particular to an antistatic precoating film and a production method thereof. Background technique [0002] Pre-coated film is a kind of flexible packaging material used for printed products. It is first coated with glue on the film by the pre-coated film processing factory according to the specifications and format, and then rewound for the manufacturer to choose, and then compounded with the printed matter. . The structure of the pre-coated film in the prior art is generally composed of a substrate and an adhesive layer, and often has the following problems: the substrate is directly bonded to the adhesive, and the bonding strength is low; the function is relatively single, and the protective effect is poor. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, an object of the present invention is to provide an antistatic precoat film. [000...
