Abstract

The invention relates to an adhesive film, in particular to a solvent-free environment-friendly flame-retardant adhesive film and a preparation method thereof.The preparation method comprises the following steps: weighing modified epoxy resin, putting into a beaker, and vacuumizing and defoaming for 2-3 times; adding a modified filler and a glass rod into the defoamed resin, uniformly stirring, dropwise adding a defoaming agent, adding an organic silicon flame retardant, and continuously stirring in a high-speed stirrer for 1-2 hours; adding a curing agent into the stirred resin filler system, and putting the resin filler system in a vacuum box for defoaming and maintaining the pressure until no bubbles exist in a glue solution; placing the treated glue solution in a vacuum drying oven at 40-55 DEG C, preserving heat for 15-20 minutes, and pre-curing until the glue solution is viscous; coating a prepared glass plate with the viscous pre-cured glue solution, and curing in a vacuum drying oven at 80-90 DEG C for 1.5-2 hours; taking the cured adhesive film down from the glass plate, and coating the surface of the adhesive film with a flexible metal solution with the thickness being 35-110 microns; and using a cutting machine for cutting into a required shape, so that the flame-retardant property of the adhesive film is improved.

Description

technical field [0001] The invention relates to an adhesive film, in particular to a solvent-free and environment-friendly flame-retardant adhesive film and a preparation method thereof. Background technique [0002] Hot melt adhesive film is a film product with or without release paper, which can be conveniently operated continuously or intermittently. It can be widely used in all kinds of fabrics, papers, polymer materials and metal bonding. When applied to some special fabrics or polymer materials, the adhesive film cannot be used in these occasions due to its flammability and poor heat resistance, such as the production of firefighting clothing. In view of this, we propose a solvent-free and environmentally friendly flame-retardant film and its preparation method. Contents of the invention [0003] An object of the present invention is to solve the above-mentioned defects in the background technology by proposing a solvent-free and environment-friendly flame-retardan...
