Abstract

The invention relates to the field of flexible package films, and concretely relates to a transparent flame-retardant antistatic polyamide film and a preparation method thereof. The film comprises a first surface layer, a middle layer and a second surface layer, at least one of the first surface layer and the second surface layer contains an antistatic agent, each of the first surface layer and the second surface layer comprises the antistatic agent, a polycarbonate resin, an ester exchange inhibitor, a polyamide resin, a flame retardant, a modified polyacrylate, an anti-blocking agent and a slipping agent, and the middle layer comprises the polycarbonate resin, the ester exchange inhibitor, the polyamide resin, the flame retardant and the modified polyacrylate. The synergistic action of the polycarbonate resin, polyether copolymerized nylon and the compounded flame retardant ensures the mechanical properties of the polyamide film, and makes the polyamide film have excellent antistaticproperty, high transparency and flame retardancy.

Description

technical field [0001] The invention relates to the field of flexible packaging films, in particular to a transparent flame-retardant and antistatic polyamide film and a preparation method thereof. Background technique [0002] Biaxially oriented nylon film (BOPA) has excellent puncture resistance, gas barrier properties, mechanical properties, optical properties, oil resistance, chemical solvent resistance, electrical insulation and wide temperature range, etc. In various fields such as daily necessities packaging and electronic product packaging, it has become the third largest biaxially oriented film after BOPP and BOPET. [0003] As we all know, the surface resistance of nylon is 10 15 ~10 16 Ω, has excellent electrical insulation. At the same time, it also causes the BOPA film to easily generate charges during the manufacturing process and lead to the accumulation of static electricity, thereby absorbing particles such as dust and impurities in the surrounding air, a...
