Abstract
The invention discloses the purposes of a kind of dialkylphosphinic salts as the additive of raising mobility of polymer composition, the add-on of described dialkylphosphinic salts accounts for 1 ~ 40% of polymer composition gross weight; Described polymkeric substance is polyester or nylon.Dialkylphosphinic salts adds in polymkeric substance as additive by the present invention, can improve the mobility of polymer composition, has greatly widened dialkylphosphinic salts range of application in the market.
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 mobility of polymer composition.
Background technology
Dialkylphosphinic salts phosphorus content is high, and Heat stability is good, work in-process do not cause the decomposition of polymkeric substance, does not also affect plastics moulding compound.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 grade, 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 mobility of polymer composition.
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 mobility of polymer composition.
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 composition gross weight.
Preferably, the add-on of described dialkylphosphinic salts accounts for 5 ~ 30% of polymer composition gross weight.
Preferred, the add-on of described dialkylphosphinic salts accounts for 10 ~ 20% of polymer composition gross weight.
Polymkeric substance of the present invention is polyester or nylon.
Described polyester is polyethylene terephthalate (PET) or polybutylene terephthalate (PBT).
Described nylon comprises the mixing of one or more in PA6, PA66, PA10, PA12, PA11, PA610, PA6T, PA10T or PA9T.
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 composition 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, adds in polymkeric substance using dialkylphosphinic salts as additive, and dialkylphosphinic salts can significantly improve the mobility of polyester or nylon composite, has greatly widened dialkylphosphinic salts range of application in the market.
