Abstract

The invention discloses a flame retardant nylon material and a preparation method thereof. The flame retardant nylon material comprises the following raw materials by weight: 200-240 parts of nylon resin, 60-80 parts of a flame retardant, 0.5-3 parts of an antioxidant, 2-6 parts of a compatibilizer, and 1-5 parts of a coupling agent. According to the invention, zinc borate subjected to surfactant modification treatment is added into the material, an original hydrophilic surface of the zinc borate is converted into a hydrophobic surface because of adsorption of surfactant molecules, and the modified zinc borate cooperates with a compatilizer maleic anhydride grafted PE or maleic anhydride grafted PP to guarantee a good disperse state of the zinc borate molecules, thus maximumly playing a flame retardant role. Therefore, the flame retardant nylon material has an excellent flame retardant effect.

Description

technical field [0001] The invention relates to a polymer material and a preparation method thereof, in particular to a flame-retardant nylon material and a preparation method thereof. Background technique [0002] Nylon has excellent comprehensive properties and occupies an important position in the field of engineering plastics. However, while having excellent performance in all aspects, nylon materials are relatively flammable, especially when electronic and electrical products are used due to faults that cause excessive temperature or high-voltage discharge, nylon is very easy to cause combustion and fire. Therefore, it is urgent and necessary to develop nylon with good flame retardancy. It is of great practical significance to improve the flame retardancy of nylon materials through flame retardant modification, and then promote the development of products in related industries to high performance and high quality. At present, there are three common methods of flame re...
