Description
Technical field
The present invention relates to the novelty teabag of dialkylphosphinic salts, particularly dialkylphosphinic salts is as the purposes of the additive of raising polymer blend electrical property.
Background technology
Dialkylphosphinic salts is high containing phosphine amount, and Heat stability is good, work in-process do not cause the decomposition of polymkeric substance, do not affect plastics moulding compound yet.Recent study shows, polymer composition containing dialkylphosphinic salts presents higher flame retardant resistance, adopting acid-base neutralisation method synthesis dialkylphosphinic salts as reported in document " synthesis of phosphinate flame retardant and fire-retardant Nylon 6 research ", have studied the flame retardant properties to PA6 simultaneously.CN200480043753.5 discloses a kind of halogen free flame retardant thermoplastic moulding compositions, and it comprises at least one dialkylphosphinic salts as halogen-free flame retardants and at least one polymkeric substance based on polyester.
Above-mentioned document shows, dialkylphosphinic salts is used in PA6, on the modified plasticss such as PET, achieve very high flame retardant effect, be added in PET, the heat produced when rate of heat release and burning sharply reduces, neat coal amout after burning increases, flame retardant properties reaches UL94 standard V-0 level, and by experiment than the PET fire retardant of present domestic use, flame retardant effect can improve 60%.
At present, dialkylphosphinic salts is widely used as a kind of fire retardant efficiently, but dialkylphosphinic salts has no report at the document of the application improving polymer composition electrical property.
Summary of the invention
The object of the present invention is to provide a kind of dialkylphosphinic salts as the purposes of the additive of raising polymer blend electrical property.
Dialkylphosphinic salts of the present invention has following structure formula I,
Wherein, R
1, R
2identical or different, be expressed as H, ethyl, propyl group, butyl, amyl group, cyclopentyl, cyclohexyl or octyl group, condition is for both can not be H simultaneously;
M is Mg, Ca, Al, Sb, Sn, Ge, Ti, Zn, Fe, Zr or Sr;
M is 2 ~ 4.
Preferably, described dialkylphosphinic salts is aluminum diethylphosphinate.
Wherein, the add-on of described dialkylphosphinic salts accounts for 1 ~ 40% of polymer blend gross weight.
Preferably, the add-on of described dialkylphosphinic salts accounts for 5 ~ 30% of polymer blend gross weight.
Preferred, the add-on of described dialkylphosphinic salts accounts for 10 ~ 20% of polymer blend gross weight.
Described polyester is polyethylene terephthalate (PET) or polybutylene terephthalate (PBT).
Dialkylphosphinic salts of the present invention can to adopt in prior art conventional synthetic method to prepare, as phospho acid sodium solution and Tai-Ace S 150 or aluminum nitrate solution are generated dialkylphosphinic salts heating and react under acidic conditions.Can the residual solvent of special low levels be contained and telomerize product in dialkylphosphinic salts.
Polymer blend of the present invention obtains by currently known methods, as by each component premix, then the material mixed is placed in twin screw extruder, by dual-screw-stem machine melting, extrudes, granulation and get final product.
The present invention finds unexpectedly, dialkylphosphinic salts is added in polyester as additive, dialkylphosphinic salts can improve the electrical property of polymer blend, the CTI value of preparation-obtained polymer blend is significantly improved, and has greatly widened dialkylphosphinic salts range of application in the market.
Embodiment
Further illustrate the present invention below by embodiment, following examples are the present invention's preferably embodiment, but embodiments of the present invention are not by the restriction of following embodiment.
the preparation of the polymer blend containing dialkyl phosphinic acid aluminium:
First by each component premix in each comparative example/embodiment (table 1), then the material mixed is placed in twin screw extruder, is melt extruded under 250 DEG C of conditions by dual-screw-stem machine, granulation, to obtain final product.Pellet 80 DEG C, continue dry 4 hours in vacuum drying oven after, pellet after gained drying is processed at the temperature of 230 DEG C ~ 300 DEG C the on-gauge plate of test standard test specimen 100*100*3mm, on-gauge plate is according to GB4207-2004, IEC112-1979 and ASTMD3638-77, regulation, regulation environment in, ± 200C, deposit 48H in humidity 45-55% environment, then carry out CTI measurement.The performance test data of each routine sample is in table 1.
The concrete proportioning of each composition and test performance result (wt%) thereof in table 1 embodiment 1 ~ 6 and comparative example 1 ~ 3
As can be seen from the results contrast of above-described embodiment and comparative example, aluminum diethylphosphinate is added in polymer blend, the CTI value of polymer blend can be significantly improved, preparation-obtained polymer blend has the characteristic of high anti creepage trace, has greatly widened dialkylphosphinic salts range of application in the market.
