Abstract

The invention discloses a 125 DEG C low-smoke halogen-free flame-retardant polyolefin material. The material is characterized by comprising the following components in parts by weight: 60-90 parts ofEVA, 40-60 parts of HDPE, 45-60 parts of aluminum hydroxide, 45-60 parts of magnesium hydroxide, 5-10 parts of a calcium-zinc composite stabilizer, 10-15 parts of a soft strength agent, 5-10 parts ofa flame retardant, 10-18 parts of a compatilizer, 1-1.5 parts of an antioxidant OSP-1, 0.5-1 part of a lubricant and 4-6 parts of a crosslinking agent. The material is an environment-friendly cable material with the characteristics of low smoke, no halogen, no toxicity, flame retardant property and high temperature resistance, and meanwhile, the mechanical property, the processability, the flame retardant property and the high temperature resistance of the cable material all reach high levels.

Description

technical field [0001] The invention relates to the field of polyolefin materials, in particular to 125°C low-smoke halogen-free flame-retardant polyolefin materials. Background technique [0002] The wire and cable industry is an extremely important part of the mechanical and electronic industry. Wire and cable are indispensable basic components for transmitting electric energy, transmitting information and manufacturing various electrical appliances and instruments, and are the basic products of electrification and informationization. Since the 1990s, China's wire and cable has been bathed in the east wind of the rapid and steady development of the national economy, and has developed rapidly. The supporting functions have grown into the second largest industry in my country's machinery industry after automobiles, and my country is a huge and growing market. China's population is one-fifth of the world's population, but cables The output value of the industry only accounts ...
