Problems solved by technology

This gas is very dangerous in a fire, because it spreads extremely fast, which seriously hinders the firefighters' rescue work in a fire, and causes great harm to people's lives and properties.
When a fire occurs, such halogen-containing flame-retardant materials will produce a large amount of smoke and toxic corrosive hydrogen halide gas, causing secondary hazards.

Abstract

The invention relates to a halogen-free flame-retardant polybutene-1 material. The polybutene-1 material is characterized by comprising following raw materials by weight: 60-90 parts of polybutene-1, 0.3-3 parts of an antioxidant, 3-35 parts of a halogen-free flame retardant and 0-4 parts of a high-temperature resistant lubricant. The product is prepared by mixing and granulating by a double-screw extruder. The material has good mechanical properties after reaching a high oxygen index and a high flame retardant level. The material adopts the halogen-free flame retardant, and therefore the material is environmental friendly, and generates no harmful gas influencing life safety of human in fire hazards. The halogen-free flame-retardant polybutene-1 material has good flame retardant effects and good mechanical properties, and widens the application scope.

Description

technical field [0001] The invention belongs to the field of modified plastics, and relates to a halogen-free flame-retardant material, in particular to a halogen-free flame-retardant polybutene-1 material and a preparation method thereof. Background technique [0002] Polybutene-1 has good physical and mechanical properties, outstanding creep resistance, low temperature resistance, environmental stress cracking resistance and high filler filling. It not only has good dielectric and chemical resistance, but also has good mechanical strength and high toughness. Its yield value, tensile strength and impact strength are 2 times, 6-10 times and 3-4 times that of LDPE respectively. Compared with other polyolefins, polybutene-1 has the best stress crack resistance. The creep resistance is higher than that of polyethylene and polypropylene, and the outstanding creep resistance remains unchanged up to 80°C under the action of stress not exceeding the yield point.
