Abstract

The invention discloses a magnesium hydroxide flame-retardant composite material and a preparation method thereof. The flame-retardant material comprises the following components in parts by weight: 20-100 parts of high polymer, 40-80 parts of magnesium hydroxide and 5-20 parts of toughening agent, wherein the high polymer is one or more of polyethylene, polyvinyl chloride, polypropylene, polystyrene, polyamide, polyformaldehyde, rubber or nylon; and the toughening agent is one or more of dioctyl phthalate, poly(ethylene-octene) elastomer, tricresyl phosphate, styrene-butadiene-styrene block copolymer, hydrogenated styrene-butadiene-styrene block copolymer or styrene-isoprene-styrene block copolymer. Practice proves that the magnesium hydroxide flame-retardant composite material has the advantages of strong shock resistance, high tensile strength and high oxygen index. The preparation method of the composite material is simple in operation, has low cost and high production efficiency,and can be widely used in the field of engineering plastics.

Description

technical field [0001] The invention belongs to the technical field of inorganic flame retardant materials, and specifically refers to a magnesium hydroxide composite flame retardant material and a preparation method thereof. Background technique [0002] At present, most of the flame retardants used in the market are halogen-containing or phosphorus-containing compounds. These substances have the characteristics of low price and good flame-retardant effect, but they will emit harmful gases when burning, which will cause personal injury and environmental damage. pollute. As the hazards of halogen compounds are gradually recognized and paid attention to, the development trend of environmental protection will prompt more and more consumers to use inorganic flame retardants that are halogen-free, low-toxic, and smoke-suppressing. The new inorganic flame retardants that have been researched and applied more at home and abroad are mainly magnesium hydroxide, aluminum hydroxide a...
