Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of polybutylene terephthalate alloy composite materials of halogen-free flameproof.
Background technology
Polybutylene terephthalate is a kind of engineering plastic materials that is widely used in fields such as automobile, building, electronic instrument.Along with fire takes place frequently, people deeply are familiar with fire retardant material, think that material itself is fire-retardant to strive for the rescue time for the prevention propagation of flame, and it is very important to save lives and properties.Therefore, most of material all requires the fire-retardant requirement that reaches certain, yet in order to reach fire-retardant requirement, a lot of materials have added halogen flame, reach fire-retardant purpose as using halogen containing flame-retardant among the Chinese patent publication number CN1060189A and containing the antimony fire retardant, these fire retardants the time can produce a large amount of poisonous and harmful smog in burning, and after goods abandon, cause antimony diffusion easily to environment such as water body, influence environment for human survival, therefore be necessary to be improved.
Summary of the invention
