Preparation of insulation sheath for chlorinated polyethylene resin/chlorinated recycled rubber universal cable
Recycled rubber(RR)is a synthetic rubber made from waste tires and other waste rubber that has been filtered,washed,stirred,and mechanically separated multiple times.It is widely used in industrial production and daily life.In order to achieve the recycling and utilization of a large amount of RR and prepare universal cable insu-lation protective sleeves,this study prepared chlorinated recycled rubber(CRR)using chlorine gas as the chlorina-ting agent,which was prepared by aqueous chlorination method.CRR was combined with chlorinated polyethylene resin to improve the quality of insulation protective sleeves.The experimental results show that as the dosage of CRR increases,the limit oxygen index(LOI)and flame retardancy of the blend material are positively correlated,and the aging resistance is significant,which meets the requirements of universal cable insulation protection sleeves.At the same time,it has the advantage of cost savings and is worth promoting.
