Abstract

The invention discloses a preparation method of a super-tough composite modified nylon master batch. The preparation method comprises the following steps: S1, weighing PA6, PA66, a flexibilizer, a nano inorganic reinforcing material and a functional additive for preparing the super-tough composite modified nylon master batch in percentage by mass; s2, adding the PA6, the PA66, the flexibilizer and the functional additive into a mixing machine, performing high-speed stirring and mixing for the first time, adding the nano inorganic reinforcing material into the mixing machine, and performing high-speed stirring and mixing for the second time to obtain a mixture; and S3, adding the mixture into a twin-screw extruder, carrying out melt blending extrusion by the twin-screw extruder, then carrying out water-cooling pelletizing, and carrying out vacuum drying to obtain the super-toughness composite modified nylon master batch. The super-tough composite modified nylon master batch prepared by a scientific and reasonable process has super-tough, so that the super-tough composite modified nylon master batch has excellent puncture resistance, the process is simple, and the super-tough composite modified nylon master batch can be better 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 method for preparing a super-tough composite modified nylon masterbatch. 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] Nylon products made of traditional nylon masterbatch can no longer meet the requirements in the occasions that require super toughness and excellent puncture resistance. Therefore, we propose a preparation method for super toughness composite modified nylon masterbatch. Solve the above-mentioned existing problems. Contents of the invention [0004] The purpose of the present invention is to provide a method for preparing a super-tough composite modified nylon ...
