preparation example Construction

[0047] The preparation method of any one of the above-mentioned PA66 composite materials, comprising the following steps:

[0048] (1) Weigh 80-100 parts of PA66, 40-50 parts of functionally modified masterbatch, 0.1-0.5 parts of antioxidant, mix and stir evenly to obtain a mixture;

[0049] (2) Extrude and granulate the mixture obtained in step (1) to obtain PA66 composite material.

[0050] The step (2) is specifically: putting the mixture obtained in the step (1) into the hopper of a twin-screw extruder to extrude and granulate to obtain a PA66 composite material, wherein the twin-screw extruder includes Six temperature zones are arranged in sequence, the temperature of the first zone is 200-220°C, the temperature of the second zone is 260-280°C, the temperature of the third zone is 260-280°C, the temperature of the fourth zone is 260-280°C, the temperature of the fifth zone is 260-280°C, The temperature in the six zones is 260-280°C, the head temperature is 260-280°C, and...

Embodiment 1

[0052] (1) Weigh 80 parts of PA66, 40 parts of functionally modified masterbatch, 0.1 part of Irganox168, mix and stir evenly to obtain a mixture;

Abstract

The invention relates to a PA66 composite material and a preparation method thereof. The PA66 composite material is prepared from the following components in parts by weight: 80-100 parts of PA66, 40-50 parts of functional modified masterbatches and 0.1-0.5 part of an antioxidant. The functional modified masterbatches is prepared from the following componnets in parts by weight: 20-40 parts of MBS, 20-30 parts of wollastonite, 40-60 parts of talcum powder, 1-3 parts of oleamide and 1-3 parts of isopropyl tris(dioctyl phosphate acyl oxide) titanate. By the technical scheme, compared with a packing used directly, the functional modified masterbatches optimizes a production environment, improves the production efficiency, and has quite high promotion value.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a PA66 composite material and a preparation method thereof. Background technique [0002] Polyamide 66 (PA66), as a common thermoplastic, is widely used. In practical applications, it is often necessary to modify PA66 to improve the rigidity or toughness of PA66 to meet the needs of different application fields. [0003] This technical solution innovatively uses functionally modified masterbatches to improve PA66 composite materials, which solves the problem of incompatibility between rigidity and toughness, and at the same time improves the rigidity and toughness of PA66 composite materials. This method has not been reported so far, which greatly expands It has widened the application range of PA66 composite material and has very practical significance. Contents of the invention [0004] The purpose of the present invention is to provide a PA66 composite material a...
