Problems solved by technology

[0005] patent (authorization number CN100532457C) discloses a method of carbon fiber reinforced halogen-free flame-retardant nylon 66, although it improves the flame retardant to a certain extent Excellent flame retardant properties and certain antistatic properties, but the process is complex and time-consuming
The patent (CN 101831172A) provides a carbon fiber reinforced nylon 66 composite material, and the patent (CN 101962477A) prepares a green halogen-free flame-retardant nylon 66 raw material. The two solve the strength and resistance of nylon 66 to a certain extent. flammability problem, but only one-sidedly optimize the performance of one aspect of nylon 66, and fail to solve the above-mentioned problems at the same time. Therefore, it is necessary to provide a nylon 66 raw material and its Preparation method is the focus of the present invention

Abstract

An environment-friendly and flame-proof nylon 66 with high conductivity and a preparation method thereof. The environment-friendly and flame-proof nylon 66 with high conductivity is prepared by carrying out high-speed mixing on a nylon 66 resin, carbon fiber filament, a phosphorus nitrogen flame retardant, a coupling agents, an antioxidant and processing agent according to a proportion, and sending the mixture into an extruder for extrusion. The nylon 66 invention obtained by the invention has obviously improved mechanical properties as well as good flame retardance and permanent antistatic performance.

Description

technical field [0001] The invention belongs to the technical field of polymer science and technology, and in particular relates to a high-conductivity environment-friendly flame-retardant nylon 66 and a preparation method thereof. [0002] Background technique [0003] As an important chemical raw material, nylon 66 has been widely used in the industries of machinery, automobiles, and instrument lamps because of its properties such as wear resistance, oil resistance, self-lubrication, and impact resistance. With the development of society, people have higher and higher requirements for safety. However, the burning characteristics of nylon 66 make it necessary to add flame retardants to meet the flame retardancy required for specific applications. Fuels can cause environmental problems. [0004] Nylon has a high surface resistance. Due to friction, etc., it is easy to accumulate charges on the plastic surface and generate static electricity, which will cause electrostatic...
