Description
Technical field
The present invention relates to auxiliary chemicals technical field, especially a kind of BACN.
Background technology
Fire retardant gives the functional aid of combustible polymers flame retardancy also known as incombustible agent, fire-proofing chemical or fireproof agent, according to should
It is divided into additive flame retardant and reactive flame retardant with mode.According to composition, additive flame retardant mainly include inorganic combustion inhibitor,
Halogenated flame retardant (organic chloride and organic bromide), phosphorus flame retardant (red phosphorus, phosphate and halogenated phosphate etc.) and nitrogen
Flame retardant etc..Fire-retardant science and technology is the needs in order to adapt to social safety production and live, and fire preventing occurs, and protects people
People's lives and properties and a science that grows up.Fire retardant is application of the flame-retarded technology in real life, and it is a kind of use
In the special auxiliary chemicals for improving flammable combustible material combustibility, it is widely used in the fire-retardant processing of all kinds of finishing materials
In.Material after fire retardant processing, when being attacked by extraneous burning things which may cause a fire disaster, can effectively prevent, delays or terminate flame
Propagation, so as to reach fire-retardant effect, fire retardant is to play its fire retardation by some mechanism, such as heat-absorbing action, cover
Lid effect, suppression chain reaction, smothering action of non-flammable compressive gas etc..
But the fire retardant of many poor qualities is flooded with Vehicles Collected from Market, not only flame retarding efficiency is poor, and difficulty can be also given out during burning
Environmental and human health impacts are caused serious harm by the smell and fog of news, are unfavorable for occurring people's escape and rescue during fire.
The content of the invention
Instant invention overcomes shortcoming of the prior art, there is provided a kind of BACN, good flame retardation effect, selected composition material
Material fusing point is high, and portion of material can be decomposited nitrogen and water by high temperature, to suppressing burning to play an important role, while will not produce during burning
Raw toxic gas, does not work the mischief to context.
In order to solve above-mentioned technical problem, the present invention is achieved by the following technical solutions：
A kind of BACN, is made up of by weight following components：10～25 parts of glass fibre, 8～14 parts of kaolin,
