Abstract
The invention discloses application of dialkyl hypophosphite as an additive for regulating deflection of a polymer composition. Addition of the dialkyl hypophosphite accounts for 1-40% of total weight of the polymer composition, and the polymer is either polyester or nylon. The application disclosed by the invention which adds the dialkyl hypophosphite to the polymer as an additive, can regulate deflection of the polymer composite; deflection of the prepared polyester or nylon composition is obviously improved, thus greatly widening application scope of the dialkyl hypophosphite in market.
Description
Technical field
The present invention relates to the new purposes of dialkylphosphinic salts, particularly dialkylphosphinic salts is as the purposes of the additive of adjustment polymer composition amount of deflection.
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, the polymer composition that contains dialkylphosphinic salts presents higher flame retardant resistance, as reported in document " the synthetic and fire-retardant Nylon 6 research of phosphinates fire retardant ", employing acid-base neutralisation method synthesizes dialkylphosphinic salts, 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, obtained very high flame retardant effect, be added in PET, the heat producing 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 capable of regulating 60%.
At present, dialkylphosphinic salts is widely used as a kind of fire retardant efficiently, and still, dialkylphosphinic salts has no report at the document of the application of adjusting polymer composition amount of deflection.
Summary of the invention
The object of the present invention is to provide the purposes of a kind of dialkylphosphinic salts as the additive of adjustment polymer composition amount of deflection.
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 that 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 diethyl phospho acid aluminium.
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 one or more the mixing in PA6, PA66, PA10, PA12, PA11, PA610, PA6T, PA10T or PA9T.
Dialkylphosphinic salts of the present invention can adopt synthetic method conventional in prior art to prepare, as phospho acid sodium solution is reacted and generates dialkylphosphinic salts with Tai-Ace S 150 or aluminum nitrate solution under heating and acidic conditions.In dialkylphosphinic salts, can contain the residual solvent of special low levels and telomerize product.
Polymer composition of the present invention can make by currently known methods, as by each component premix, then the material mixing is placed in to twin screw extruder, by dual-screw-stem machine melting, extrude, and granulation and get final product.
The present invention finds unexpectedly, using dialkylphosphinic salts as additive, add in polymkeric substance, dialkylphosphinic salts can be adjusted the amount of deflection of polymer composition, the amount of deflection of the composition of preparation-obtained polyester or nylon obviously improves, and has greatly widened the range of application of dialkylphosphinic salts in market.
