Highly heat-resistant radiation-resistant cable jacket compound

Abstract

The invention relates to the field of electric wire and cable, and particularly relates to a highly heat-resistant radiation-resistant cable jacket compound. The highly heat-resistant radiation-resistant cable jacket compound is prepared from the following materials in parts by weight: 60-95 parts of chlorinated polybutadiene, 40-60 parts of vinyl chloride resin, 10-20 parts of surfactant, 6-13 parts of sodium bentonite, 8-15 parts of copper ammonia fiber, 6-11 parts of dimethyl nylon acid, 4-10 parts of modified inorganic filler, 10-20 parts of expanded graphite, 5-11 parts of flame retardant, 10-13 parts of calcium stearate, and 3-5 parts of antioxidant. The highly heat-resistant radiation-resistant cable jacket compound is complete and reasonable in material, and the produced jacket isexcellent in physical property, and strong in tensile strength, tearing strength and resilience performance; and the jacket has good heat resistant, flame resistant, radiation resistant, ozone resistant, acid and alkali resistant, and chemical reagent resistant properties, and is low in production cost and long in service life.

Description

technical field [0001] The invention relates to the field of grape fertilizers, in particular to a high heat-resistant and radiation-resistant cable sheathing material. Background technique [0002] With the gradual acceleration of urbanization, urban planning is becoming more and more modern. In the process of urban construction, cable entry into the ground has become the minimum construction requirement. At the same time, in the process of urban transformation, it is also necessary to put various cables erected in the air into the ground. At present, the construction of cables into the ground often adopts non-excavation technology. This construction method has the advantages of no impact on traffic, little damage to the stratum structure, and short cycle. , has the performance: the cable needs to have high strength, good rigidity and toughness, etc. In addition, due to the characteristics of the cable itself, it also needs to have the characteristics of high flame retard...
