Abstract

The invention discloses a POM flame retardant plastic and a preparation method thereof, and the POM flame retardant plastic is prepared from the following materials in parts by weight: 150 to 200 parts of POM resin, 25 to 30 parts of melamine, 10 to 15 parts of sodium silicate, 2 to 8 parts of palladium dichloride (triphenylphosphine), 2 to 5 parts of aluminium hydroxide, 2 to 5 parts of talcum powder, 2 to 8 parts of triallyl isocyanurate, 3 to 5 parts of potassium perrhenate, 1 to 3 parts of kaolin, 0.5 to 2 parts of tantalum pentoxide, 0.1 to 1 part of lanthanum hexaboride and 2 to 10 parts of fire resistant fibre. The POM flame retardant plastic provided by the invention has excellent heat resistance and flame resistance and higher tensile strength, breaking elongation, impact strength, bending strength and oxygen index; the preparation process is simple, the cost of a product is low, the comprehensive performance of the product is excellent, a halogen-flame retardant is not adopted, hydrogen halide is not emitted in a burning process, the human health is protected and the promotion value is good.

Description

technical field [0001] The invention relates to a plastic, in particular to a POM flame-retardant plastic and a preparation method thereof. Background technique [0002] With the continuous development of science and technology and economy, daily necessities made of plastics play an increasingly important role in daily life. However, plastics are easy to burn, and the burning speed is fast, and a large amount of toxic gases will be produced. With the wide application of plastics in construction, furniture, transportation, aviation, aerospace, electrical appliances, etc., at the same time, there are countless fires caused by plastic products. The fire situation is not optimistic. Some major fire accidents occur frequently, and many of them are nylon mesh, Flammable materials such as polyurethane foam burn rapidly, causing death, injury and property damage. The vast majority of plastics are flammable substances, but in plastic construction materials, transportation materials...
