Preparation and Flame Retardant of Porous Composite Materials Based on Silicone Rubber/Zinc Borate Porcelain
New energy is in the stage of rapid development,but also facing many problems such as batteries,safety.Among them,the problem of lithium battery deflagration has limited the development of new energy vehicles.To address this problem,the composite diatomaceous earth-silicone rubber material with good adhesion was used as the matrix and zinc borate was added as the flame retardant material to study the flame retardant performance and the porcelain effect at high temperature of the composite diatomaceous earth-silicone rubber material.The composite material was characterized by SEM,XRD,TG and other testing methods.The results showed that the samples had good flame retardant effect.The zinc borate inside the sample produced B2O3 under pyrolytic conditions,and the high temperature calcination accelerated the pyrolysis of the composite silicone rubber and eutectic with SiO2,which promoted the porcelainization process and produced continuous bridging structure.This study helps to mitigate the combustion flame retardant problem of lithium batteries and reduce the combustion hazard of new energy vehicles.
