High-transparence toughened PA12/PA56 alloy material and preparation method thereof

Abstract

The invention provides a high-transparence toughened PA12 / PA56 alloy material. The high-transparence toughened PA12 / PA56 alloy material can be used in the field of special industries with high transparence requirement. The formula of the material comprises 10-30 wt% of PA12 resin, 55-86.9 wt% of PA56 resin, 2-8 wt% of a flexibilizer, 0.2-2 wt% of light guiding powder, 0.2-1 wt% of an antioxidant, 0.5-2 wt% of a lubricant and 0.2-2 wt% of a nucleation inhibitor. A preparation method of the material comprises the following steps: uniformly stirring all component raw materials through a high mixer, adding the stirred raw materials to a double screw extruder, carrying out melt extrusion, cooling the extruded material, air-drying the cooled material, granulating the air-dried material, and strongly magnetizing obtained granules to obtain the material. The material has high toughness, has the transparence comparable to common nylon, and can be used in the fields of the aviation industry, automobile manufacturing, the electric appliance industry, image, medical science and food packaging.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a method for preparing a high-permeability and toughening PA12 / PA56 alloy material. Background technique [0002] Nylon, that is, polyamide (PA), is a polymer compound containing amide groups (-NHCO-) ​​in the main chain. It is one of the general engineering plastics, and its consumption ranks first among the five general engineering plastics. most in demand. Nylon has good mechanical properties due to the strong polarity between molecules, and is widely used in industrial fields such as machinery, automobiles, and instruments. [0003] In recent years, in addition to the two veterans of PA6 and PA66, many new faces have emerged in the nylon family, such as PA46, PA1010, PA11, PA12, PA9T, PA10T and semi-aromatic nylon, some of which have been put into industrial production. PA56 and PA12 are just one of these rising stars. [0004] PA56 is a new type of bio-based nylon indepen...

Problems solved by technology

[0006] In view of the fact that most of the research on the toughening of nylon alloys at home and abroad only stays in the ordinary toughening of conventional nylons such as PA6 and PA66, there are relatively few studies on its transparent toughening modification, let alone those new nylons.
