Problems solved by technology

In addition, the anti-hydrolysis agents used for hydrolysis-resistant nylon at home and abroad are mainly concentrated in the use of polycarbodiimide. The typical representative product is Stanboxol-P of German Rheinland Chemical Company; and H3337 / H3347 of German BRUGGOLEN Company. It is a mixture of copper compound antioxidant, synergist, nucleating agent and effective hydrolysis protection lubricant (fatty acid salt), and also has good hydrolysis resistance, but it is added in a large amount and the cost is high

Abstract

The invention relates to a glass fiber reinforced and hydrolysis-resistant nylon PA (Polyethylene) 6/PA66 composite material and a preparation method thereof. The composite material comprises the following components: PA6, PA66, hydrolysis-resistant alkali-free glass fibers, a compatilizer, a main hydrolysis resisting agent, an epoxide assistant hydrolysis resisting agent, a nucleating agent, an antioxidant that is the 1010 and 168 compounded antioxidant, a lubricant and simethicone. The preparation method comprises the following steps: placing the PA6, the PA66, the compatilizer and the simethicone into a high-speed mixer to mix according to the formula mass; adding each assistant mentioned above; mixing by the high-speed mixer; transferring into a twin-screen extruder; and molting, extruding, blanking and drying the materials, so as to obtain the composite material. The glass fiber reinforced and hydrolysis-resistant nylon PA6/PA66 composite material has the advantages of being high in bending strength, excellent in toughness and hydrolysis resistance and wide in applicable scope, is mainly applicable to components of controllers of electric bicycle, and can meet the requirement of the performance of the materials.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a method for preparing a glass fiber-reinforced hydrolysis-resistant PA6 / PA66 composite material. Background technique [0002] As we all know, polyamide (nylon) resin plays a dominant role in mechanical structural parts due to its good mechanical properties, and is the most used variety in engineering plastics, among which PA6 and PA66 are the main ones. Performance plays an important role. [0003] The melting point of PA6 is 215°C-225°C, which is lower than that of PA66, and the flexural strength and flexural modulus are also lower. The water absorption is larger than that of PA66, but the toughness of PA6 is better than that of PA66. The rigidity of PA66 is better than PA6, the heat resistance is better than PA6, the melting point is 260°C-265°C, the molding cycle is short, and the oil resistance is good. In practical applications, PA6 and PA66 are often mixed to make PA6...
