Abstract

The invention discloses a high-barrier nylon master batch for a food packaging material. The formula of the high-barrier nylon master batch for the food packaging material comprises the following components in percentage by mass: 40.0%-80.0% of PA6, 10.0%-50.0% of PA12, 1%-5% of an oxygen absorbent, 1%-5% of a layered nano inorganic material and 0.5%-7.0% of a functional additive. The invention also discloses a preparation method of the high-barrier nylon master batch for the food packaging material. The high-barrier nylon master batch for the food packaging material, which is prepared by a scientific and reasonable formula and process, can be used for preparing a food packaging film, so that the film has excellent oxygen barrier property, the problem that the barrier property of the packaging material is greatly reduced after the service life of an oxygen absorbing material expires is solved, and the high-barrier nylon master batch is simple in process, and can be produced and applied in a large scale.

Description

technical field [0001] The invention relates to the technical field of nylon material modification, in particular to a high-barrier nylon masterbatch for food packaging materials and a preparation method thereof. Background technique [0002] Nylon is the first synthetic fiber to appear in the world, and nylon is a term for polyamide fiber (nylon). The emergence of nylon has brought a new look to textiles. Its synthesis is a major breakthrough in the synthetic fiber industry and a very important milestone in polymer chemistry. [0003] The oxygen barrier performance of the current nylon masterbatch used for food packaging films is poor, and the barrier performance of the packaging material will be greatly reduced after the life of the oxygen-absorbing material expires. Therefore, we propose a food packaging A high-barrier nylon masterbatch of materials and a preparation method thereof are provided to solve the above-mentioned existing problems.
