Abstract

Flame-retardant and reinforced integrative natural rubber and a preparation method thereof relate to rubber and a preparation method thereof. The raw material formula consists of natural rubber(NR), epoxy natural rubber(ENR), chloroformylated graphene, a self-made flame retardant, stearic acid, zinc oxide, accelerator CZ, antioxidant 4010, carbon black and liquid paraffin. Epoxy natural rubber and natural rubber have a similar structure and good interfacial compatibility therebetween, ring-opening reaction between epoxy groups on the surface of epoxy natural rubber and active hydrogen can be performed. Therefore, according to the invention, the self-made high-efficient and environment-friendly flame retardant is grafted to the ENR matrix, chloroformylated graphene is employed to perform reinforcement modification on the ENR modified by the flame retardant, and then the flame retardant and graphene are grafted to the rubber matrix by co-vulcanization of natural rubber and epoxy natural rubber during processing. According to the invention, dispersibility of the flame retardant and graphene is well improved and thus flame retardancy and mechanical properties of the material are easy to improve.

Description

technical field

[0001] The invention relates to a rubber and a preparation method thereof, in particular to a flame-retardant reinforced integrated natural rubber and a preparation method thereof.

[0002] technical background

[0003] Natural rubber (NR) is widely used in various fields due to its excellent physical and mechanical properties. However, its inherent high flammability limits the application of NR. With the continuous advancement of science and technology, people hope to prepare natural rubber materials with better mechanical properties and certain fire safety performance. Therefore, improving the mechanical properties of flame-retardant natural rubber and its products is a scientific research problem to be solved urgently at home and abroad. As we all know, adding flame retardants to rubber is a direct and effective way to make rubber flame retardant. At present, most of the widely used flame retardants are halogen flame retardants. Although the flame retarda...
