Abstract

Rubber materials, known for their excellent physical and mechanical properties, are widely used in products such as tires, shock absorbers, and conveyor belts. However, most rubbers have a low limiting oxygen index (LOI) and are considered flammable materials, which limit their application in certain fields. Preparing rubber materials with good flame retardancy has become a key research topic. This paper mainly discusses the intrinsic flame retardancy, inorganic filler flame retardancy, nano-technology flame retardancy, and polymer flame retardancy from the aspects of chemical grafting and physical blending. It summarizes the research progress in the field of flame-retardant rubber over the past five years and predicts the research trends of flame-retardant rubber materials.

Keywords: flame retardancy of rubber; chemical modification; physical blending; intrinsic flame retardancy
