Problems solved by technology

However, the disadvantages of high-temperature-resistant nylon, such as poor fluidity, poor processing performance, and mechanical properties that cannot meet industrial requirements, are becoming more and more obvious. Therefore, it is particularly important to seek a high-temperature-resistant nylon with excellent mechanical properties, processing properties, and flow properties.

Abstract

The invention belongs to the technical field of engineering plastics, and relates to a HPN (high temperature resistant nylon) / TLCP (thermotropic liquid crystal polymer) / HNTs (halloysite nanotubes) composite nano material and a preparation method thereof. The material comprises the following components by weight: 70-80 parts of semi aromatic nylon, 5-15 parts of thermotropic liquid crystal polymer, 10-20 parts of halloysite nanotubes, 0.2-0.5 part of a compatible agent, 0.3-1 part of a lubricant and 0.5-0.2 part of an antioxidant. Compared with the prior art, the HNTs can be well compatible with the high temperature resistant nylon, and is good in self dispersivity and not easy to agglomerate, so that the HPN / TLCP / HNTs composite material with high strength, high rigidity, heat resistance and excellent chemical stability performance can be obtained, the HPN / TLCP / HNTs composite material is added with HNTs relatively cheap in price, and avoids the disadvantage of too high use cost caused by single use of the high temperature resistant nylon and the TLCP, and the preparation method is simple in process.

Description

technical field [0001] The invention belongs to the technical field of engineering plastics, and relates to a semi-aromatic nylon / thermotropic liquid crystal polymer / halloysite nanotube (HPN / TLCP / HNTs) composite material and a preparation method thereof. Background technique [0002] In recent decades, nylon has made great progress in industry and life. However, due to the development of the electrical and electronic industry in recent years, especially the widespread use of SMT (Surface Mount Technology), the requirements for various properties such as high temperature resistance of materials in the industry are getting higher and higher. With its high melting point and good mechanical properties, high temperature resistant nylon has gradually opened up a world in the current industry. [0003] At present, the most used high-temperature resistant nylon is DSM (DSM) PA46, but because PA46 is aliphatic nylon, it is still inferior to aromatic or semi-aromatic nylon in terms o...
