The polyamide film functional master batch provided by the invention is free of added migration slipping agent, and is suitable for being added on a corona surface and a non-corona surface of a film when a biaxially oriented polyamide film is produced; by adding the functional master batch, the die head material deposition in the production process of the polyamide film can be reduced, and the time interval of 'lip cleaning' during shutdown is prolonged; the prepared polyamide film has low friction coefficient, no small molecule transfer and no corona attenuation in special environment.
Description
Technical Field
The invention relates to a functional master batch, in particular to a biaxially oriented polyamide film functional master batch and a preparation method thereof.
Background
The polyamide film has the characteristics of excellent high barrier property, puncture resistance, low temperature resistance, oil resistance, flexibility and the like, and is widely applied to the fields of daily necessities, electronic products, food, medicines and the like as a packaging material.
In the actual production process of the biaxially oriented polyamide film, a large amount of material is deposited on a die after continuous production for about 6-12 hours, and if the die is not stopped for 'lip cleaning', the film breaking frequency is increased and the surface of the film is scratched by the deposit. In order to ensure that the polyamide films are not stuck together, an anti-sticking master batch concentrated by an opening agent and a slipping agent is required to be added into the polyamide films so as to ensure the normal production, storage and transportation and subsequent processing application of the plastic films.
In the polyamide anti-sticking master batch in the prior art, a migrating slipping agent such as amide wax is added to reduce the friction coefficient of the polyamide film and improve the slipping effect of the film. For example, chinese patent 97122705.5, filed by emmes-intevetta, switzerland, uses N, N' -ethylene-bis-fatty acid amides as slip agents; chinese patent CN1775858 applied by chinese petrochemical company limited uses stearamide, erucamide, ethylene bis stearamide, stearic acid erucamide, and stearyl alcohol, stearate or montanate as slipping agent. The slipping mechanism of the amide wax migration slipping agent is as follows: the molecules of the slipping agent migrate to the surface of the film to form a layer of crystalline wax, so that the friction coefficient of the surface of the film is reduced. However, if the molecular migration of the slip agent is too large, the corona value on the surface of the film is lowered, which affects the printing effect of the polyamide film, and the composite strength of the polyamide film is lowered.
Therefore, how to solve the adverse effect of the migrating slipping agent in the existing anti-sticking master batch on the polyamide film is solved, and meanwhile, the obtained anti-sticking master batch can prolong the 'lip cleaning' time interval during the production of the polyamide film and ensure the processing continuity of the polyamide film, so that the continuous production time of the polyamide film is prolonged, which is the demand of various current polyamide film manufacturers.
