Abstract

The invention belongs to the field of flame-retardant cables, and particularly relates to a low temperature-resistant polyolefin flame-retardant cable material. The low temperature-resistant polyolefin flame-retardant cable material is prepared from the following raw materials in parts by weight: 60 to 80 parts of a polyolefin elastomer composite material, 10 to 20 parts of an antioxidant, 5 to 8 parts of citrate, 0.5 to 1 part of 50 DEG C-resistant lubricating oil, 2 to 4 parts of di-tert-butyl peroxide, 2 to 4 parts of bisphenol A disalicyate, 5 to 8 parts of pigment red, 3 to 6 parts of bismaleimide and 30 to 45 parts of an inorganic flame retardant. The invention also discloses a preparation method for the low temperature-resistant polyolefin flame-retardant cable material. The low temperature-resistant polyolefin flame-retardant cable material prepared by the preparation method has low temperature resistance, excellent mechanical properties and good flame retarding effect, and has a wide market popularization value.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of flame-retardant cable materials, in particular to a low-temperature-resistant polyolefin flame-retardant cable material and a preparation method thereof. [0003] 【Background technique】 [0004] Wire and cable are important equipment for electric power industry. In the process of industrial, agricultural and commercial development, the transmission of data by cables is inseparable. However, in the process of actual application of cables, due to the influence of external factors and the reasons of the cables themselves, the cables may catch fire. Once the cables happen Fire, it will spread along the cable to the surrounding flammable objects, and once the fire spreads, the fire speed will be very fast. The loss of personnel and equipment may also lead to environmental pollution. Therefore, the flame retardant and fireproof technology of wire and cable has become an important research topic in fire protecti...
