Silicon/nitrogen synergistically reinforced flame-retardant PA6 nanocomposites with simultaneously improved anti-dripping and mechanical properties

Abstract

A facile route was provided to prepare silicon/nitrogen synergistically reinforced flame-retardant PA6 nanocomposites with simultaneously improved anti-dripping and mechanical properties.

Flame‐retardant polyamide 56 with high fire safety and good thermal performance

“…However, various problems have existed in blending modification, such as poor dispersibility, weak compatibility, and easy leaching in matrix materials 13,14 . In contrast, copolymerization flame retardant modification for PA56, namely the chemical introduction of reactive flame retardants into the PA56 mainchain, is regarded as an ideal method for endowing PA56 with flame retardancy 15–17 . Incorporation of reactive flame retardants at lower levels can effectively improve the flame‐retardant characteristics of polyamides with little loss in the thermal performance of the materials 18–20 .…”

[15][16][17] Incorporation of reactive flame retardants at lower levels can effectively improve the flame-retardant characteristics of polyamides with little loss in the thermal performance of the materials. [18][19][20] The generation of flame-retardant PA56 by the incorporation of reactive flame retardant monomers during the polymerization has not often been reported.…”

Flame retardant chloroprene rubbers with high tensile strength and elongation at break via dual cross-linked networks

“…Melamine cyanurate (MCA) is a kind of green and environmentally friendly ame-retardant and its application in plastics has received more and more attention. [27][28][29][30] MCA is very stable within 300 C, and decomposes above 600 C. 31 Moreover, MCA is a nitrogen-based, intumescent ame retardant. The vulcanizate added with MCA has excellent ame-retardant properties, and low smoke density during combustion and rarely produces toxic and corrosive gases.…”

Graphene oxide/chitosan nano‐coating with ultrafast fire‐alarm response and flame‐retardant property

“…13 On the other hand, when a fire occurs, the coating plays an effective barrier to combustible materials, making the combustible materials heat insulation. 14 If the coating can intelligently respond to the changes in the external environment during a fire, it will greatly improve the response speed of flame detection and effectively improve the reliability of the fire-warning system. 15,16 Graphene oxide (GO) is the oxidative state of graphene.…”
