Abstract

The invention relates to a high-performance flame-retardant nylon 6 alloy and a preparation method thereof, which is made of the following components by weight: 70-90 parts of PA6, 10-16 parts of treated basic magnesium sulfate whiskers, 1-5 parts of nano silicon dioxide, 0.2-0.5 parts of antioxidant. Use a twin-screw extruder to uniformly mix PA6, treated basic magnesium sulfate, and nano-silicon dioxide, and granulate to obtain the product. PA6 has excellent comprehensive performance, good insulation, wear resistance, oil resistance, and better molding performance, but some of its physical properties and flame retardancy are not good, which greatly limits its application in some fields. The innovative addition of treated basic magnesium sulfate whiskers and nano silicon dioxide in the invention improves the flame retardancy and physical properties of the PA6 alloy, which greatly expands the application field of the material and has very important practical significance.

Description

technical field

[0001] The invention relates to the technical field of polymer materials, in particular to a high-performance flame-retardant PA6 alloy and a preparation method thereof. Background technique

[0002] Nylon 6 (PA6) is an engineering plastic with excellent comprehensive properties. It has good dimensional stability, good insulation, wear resistance, oil resistance, and good molding and processing performance. However, some of its physical properties and flame retardancy are not good, which greatly limits its application in some fields. Aiming at this situation, the present invention innovatively adds treated basic magnesium sulfate whiskers and nano silicon dioxide to improve the flame retardancy and physical properties of the PA6 alloy, which greatly expands the application field of the material and has a very important Practical significance. Contents of the invention

[0003] The object of the present invention is to provide a high-performance flame-reta...
