Abstract

The invention discloses a phosphorus, nitrogen and bromine compound system fire retardant which comprises the following raw materials in parts by weight: 50-65 parts of melamine hydrobromide, 50-65 parts of ammonium polyphosphate and 4.5-6 parts of fire retarding synergism synergist. The fire retardant integrates the advantages of a phosphorus based fire retardant and a bromine based fire retardant, so that properties of the phosphorus based fire retardant and the bromine based fire retardant are complemented. In addition, antimony trioxide is replaced by the fire retarding synergism synergist, so that consumption of the fire retardant is reduced, and the fire retarding property, the processablility and the physical and mechanical properties of a material are improved. The fire retardant can be directly added and filled in to be processed into a product, so that a processing technique is simple; the production cost is lowered; furthermore, the compound fire retardant is added to the material to ensure that the bromine content of the material is low (approximately a halogen-free requirement is met in a modified product); and modern high-efficiency and environment-friendly requirements are met.

Description

technical field [0001] The invention relates to a phosphorus-nitrogen-bromine composite system flame retardant and a preparation method thereof, belonging to the field of functional polymer materials. technical background [0002] With the continuous improvement of the economy and technology level, the polymer material industry has developed rapidly. The three major synthetic materials - rubber, plastics and fibers are more and more used in various sectors of the country's economy and in various fields of people's daily life, but most Polymers are flammable and combustible materials, and when burning, they have a large heat release rate, high calorific value, fast flame propagation speed, are not easy to extinguish, and sometimes produce thick smoke and toxic gases, causing environmental hazards and people's lives. Safety poses a huge threat. According to the latest statistics from relevant departments, a considerable part of the fires that have occurred in recent years are...
