Problems solved by technology

However, there is a large limit to the amount of modifier added, the modification effect is not obvious if added less, and the performance of the matrix material will be adversely affected if added too much
For nanofillers such as carbon nanotubes and graphene, they are very easy to agglomerate in the blend system, and with the increase of the added amount, the viscosity of the system will also increase sharply, which seriously affects the material molding process

Abstract

The invention relates to the technical field of nylon composite materials, and particularly provides an antistatic flame-retardant nylon composite material and a preparation method thereof. The antistatic flame-retardant nylon composite material comprises nylon resin, flame retardants and carbon nanotube / graphene staple fibers in a weight ratio of 1:(0.002-0.02):(0.15-0.45).

Description

technical field [0001] The invention relates to the technical field of nylon composite materials, and more specifically, the invention provides an antistatic and flame-resistant nylon composite material and a preparation method thereof. Background technique [0002] The strength of polyamide fiber is 1-2 times higher than that of cotton, 4-5 times higher than that of wool, and 3 times that of viscose fiber. However, the heat resistance and light resistance of polyamide fiber are poor, and the retention is not good, and the clothes made of it are not as crisp as polyester. In addition, both nylon-66 and nylon-6 used for clothing have the disadvantages of poor hygroscopicity and dyeability. For this reason, new polyamide fibers of nylon-3 and nylon-4 have been developed. Lightweight, excellent wrinkle resistance, good air permeability, good durability, dyeability and heat setting, etc., so it is considered to be very promising. [0003] With the miniaturization of automobile...
