Abstract
The invention discloses an application of an additive of dialkyl phosphinate in improvement of electrical property of a polyester composition. The adding amount of the dialkyl phosphinate is 1-40 percent of the total weight of the polymer composition. According to the application, the dialkyl phosphinate as an additive is added in polyester, and the dialkyl phosphinate is capable of improving electrical property of the polyester composition; and the CTI (Comparative Tracking Index) value of the prepared polyester composition is remarkably improved, and the application age of the dialkyl phosphinate in the market is greatly enlarged.
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 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, 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 can improve 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 that improves polymer composition electrical property.
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 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 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 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 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 blend 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, add in polyester dialkylphosphinic salts 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 the range of application of dialkylphosphinic salts in market.
Embodiment
Further illustrate the present invention below by embodiment, following examples are preferably embodiment of the present invention, but embodiments of the present invention are not subject to the restriction of following embodiment.
the preparation of the polymer blend that contains dialkyl phosphinic acid aluminium:
First by the each component premix in each comparative example/embodiment (table 1), then the material mixing is placed in to twin screw extruder, melt extrudes under 250 ℃ of conditions by dual-screw-stem machine, granulation, to obtain final product.Pellet continues after dry 4 hours in 80 ℃, vacuum drying oven, after gained is dry, pellet is processed into the on-gauge plate of test standard test specimen 100*100*3mm at the temperature of 230 ℃ ~ 300 ℃, on-gauge plate is according to GB4207-2004, IEC112-1979 and ASTM D3638-77, regulation, regulation environment in, ± 200C, in humidity 45-55% environment, deposit 48H, then carry out CTI measurement.The performance test data of each routine sample is in table 1.
Concrete proportioning and the test performance result (wt%) thereof of each composition in table 1 embodiment 1 ~ 6 and comparative example 1 ~ 3
Result by above-described embodiment and comparative example relatively can be found out, in polymer blend, add diethyl phospho acid aluminium, can obviously improve the CTI value of polymer blend, preparation-obtained polymer blend has the characteristic of high anti creepage trace, has greatly widened the range of application of dialkylphosphinic salts in market.
