Description

Halogen-free flame retardant PC-PET alloy film and preparation method thereof
Technical field
The invention belongs to the polyester film production field, be specifically related to a kind of halogen-free flame retardant PC-PET alloy film and preparation method thereof.
Background technology
Polycarbonate (PC) is one of widely used five large-engineering plastics, its transparency is good, have good comprehensive mechanical performance, high heat resistance, high electric insulation performance, thereby each field such as electronic apparatus, automobile, medicine have been widely used in, especially the application on the senior electrically insulating material of electronic apparatus has the status that can not be substituted.
The flame retardant rating of PC material itself meets UL94 V-2 rank, belongs to from putting out level.But along with the development of society, in a lot of industries, electronic enterprises especially, other requirement is more and more higher to flame retardant grade, need all to begin the fire-retardant requirement of V-0 or VTM-0 in the requirement of a lot of appliance materials.
There is Patent document data to report the very effectively fire retardant of a kind of PC of can be used for: organic aromatic sulfonic acid salt, such as basic metal or the alkaline earth salt with the aromatic sulfonic acid of inhaling the electricity base, this based flame retardant advantage is that the adding of extremely a small amount of fire retardant can significantly improve the flame retardant effect of PC base material.But when running into the higher fire-retardant occasion of requirement, when requiring such as the thick PC film UL94 V-0 of 0.43mm, only depend on the fire retardant effect of this class not reach requirement.It is composite such as publication number to be that the patent document of CN200910183582.0 carries out phosphorus flame retardant and Sulfonates fire retardant, and the PC inflaming retarding membrane of working it out also can only reach VTM-0, does not still reach the fire-retardant requirement of UL94 V-0.It is work in conjunction with forefathers that scheme is also arranged, and the flame-retardant additive of phosphorus system, sulphur system, silicon system, fluorine system is carried out quantitatively composite, has finally realized the fire-retardant requirement of the 0.43mmV-0 of PC film.But the formulation cost of the halogen-free flame retardant PC film of the preparation of this patent will be greatly very high, can allow the downstream terminal client accept on use cost.Add in addition the PC film of a large amount of fire retardants, even if reach the fire-retardant requirement of UL94 V-0, the mechanical property of PC film, thermotolerance, electrical insulation capability all will be greatly affected, and also can have influence on the application of terminal client.
The client of electronic enterprises is considering on the use cost, also can select BOPET to come for insulating material, compare with PC, BOPET also possesses higher thermotolerance and electrical insulation capability, and cost is lower than PC, but the flame retardant properties of BOPET is but not as PC, very easy burning drippage, the adding of anti-dripping agent can significantly improve the anti-performance of dripping really, but the unstable on simultaneously again can stretch processes being prone to stretch fluctuation and rupture of membranes.
Summary of the invention
The present invention is high in order to solve existing Halogen V-0 fire retardation PC film use cost, the problem of mechanical property deviation, advantage in conjunction with PC material resistance to elevated temperatures, high electric insulation performance, flame retardant properties, and the superiority of effectiveness of PET material, a kind of halogen-free flameproof rank PC/PET alloy film is provided, and its another one purpose has provided this material preparation method, and the halogen-free flameproof rank PC/PET alloy film cost that obtains is low, fire-retardant rank reaches UL94 V-0, and comprehensive mechanical property is better.
