Heat-resistant and flame-retardant modified natural rubber cable sheath material

Abstract

The invention discloses a heat-resistant and flame-retardant modified natural rubber cable sheath material. The material is prepared from natural rubber, nitrile rubber, ethylene propylene diene monomer, silazane silicone rubber, stearic acid, magnesium oxide, dicumyl peroxide, 1,3,5-trithione-2,4,6-symtriazine, 1,1-di-tert-butylperoxide-3,3,5-trimethyl-cyclohexane, manganese phosphate, magnesium hydrate, modified carbon nanotube, zirconium diboride, anti-aging agent, accelerant M, accelerant TMTD, poly brominated diphenyl ethers, trioctyl trimellitate, dimethyl methylphosphonate and polyoxyethylene rosin ester. The material has excellent heat resistance and flame retardance, is high in strength and long in service life, and can meet the use requirements of cable sheath materials in various fields.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a heat-resistant and flame-retardant modified natural rubber cable sheath material. Background technique [0002] Natural rubber has excellent properties such as resilience, insulation, water resistance and plasticity. It has been widely used in daily life, medical and health care, transportation, industry, agriculture and other fields. It is also one of the commonly used materials for cable sheaths. With the development of the economy, the places where cables need to be used have become diversified, and there are more stringent and diverse requirements for the performance indicators of cable sheath materials, such as insulation, tensile strength, heat resistance, flame retardancy, etc. The indicators have strict requirements, and the continuous improvement of the performance of the sheath material is an urgent need for economic and social development. Traditional natural...

With the development of the economy, the places where cables need to be used have become diversified, and there are more stringent and diverse requirements for the performance indicators of cable sheath materials, such as insulation, tensile strength, heat resistance, flame retardancy, etc. The indicators have strict requirements, and the continuous improvement of the performance of the sheath material is an urgent need for economic and social development. Traditional natural rubber sheath materials often have problems such as unsatisfactory flame retardancy and heat resistance, and short service life. It brings a lot of inconvenience to the actual use, and even threatens the safety of people's lives and property. Therefore, it needs to be modified
