Description
Technical field
The present invention relates to the inorganic combustion inhibitor technical field, be specifically related to a kind of antimony trioxide synergist and contain the flame retardant polyester or the polyester alloy of this antimony trioxide synergist.
Background technology
For many years, weisspiessglanz (Sb

In addition, Sb2O3 also can be composite with aluminium hydroxide, zinc borate, fluoroborate etc., not only can reduce the consumption of Sb2O3, and the amount of being fuming also greatly reduces; The somebody has carried out the composite research of ZnO or MoO3 and Sb2O3 in addition, and the compound that obtains has good fire-retardant, smoke-suppressing, and has static resistance concurrently.
For a long time, people are seeking the synergistic agent that can match in excellence or beauty with weisspiessglanz always, even to this day, do not find complete ideal weisspiessglanz surrogate as yet.
Therefore, find a kind of synergistic agent of antimonous oxide cheaply to reduce the consumption of antimonous oxide in flame retardant polyester and the alloy thereof, improving still from material property, cost control all has sizable meaning.
Summary of the invention
Purpose of the present invention is intended to disclose a kind of antimony trioxide synergist, replaces Sb2O3 to be used for flame retardant polyester plastics and alloy thereof with part, when keeping its excellent flame, reduces its side effect and fire-retardant cost in polyester processing.
A kind of antimony trioxide synergist is characterized in that by magnesium oxide or contains magnesian mixture forming.
But magnesian mixture MgO and the SiO of containing of the present invention
2Binary mixture, its weight ratio is 1: 2-2: 3; Also MgO, SiO2 and Fe
2O
3Tertiary mixture, its weight ratio are 1: 2: 0.006.
In embodiment of the present invention, described antimony trioxide synergist can partly replace antimonous oxide commonly used in flame retardant polyester and the alloy thereof, keeps identical flame retardant rating, and the replacement amount can be 5-75%, preferred 20-60%, best 35-50%.
In embodiment of the present invention, the whiteness of described antimony trioxide synergist is greater than 95%, fineness 6000-25000 order, median size 0.80-2.5 micron.
On the one hand, the present invention also provides a kind of flame retardant polyester or polyester alloy that contains antimony trioxide synergist of the present invention.
Described polyester comprises PBT and PET, and wherein the relative viscosity of PBT is 0.8-1.5PaS, and melt temperature is 225-240 ℃, and the relative viscosity of PET is 0.8-1.0PaS, and melt temperature is 250-260 ℃.
Described polyester alloy comprises the PBT/ABS alloy, PET/ABS alloy, PBT/PET alloy.
Described ABS is vinyl cyanide, divinyl and styrene copolymer, and its rubber content is 35%-70%, and relative density is 1.0-1.04, and melt temperature is 190-220 ℃.
In embodiment of the present invention, described polyester alloy is formed by the feedstock production of following weight part:
PBT 0~90
PET 0~90
ABS 0~50
Nucleator 1~7
Sb
2O
3 1~6
Sb
2O
3Synergistic agent 0.5~4
Fire retardant 1~20
Oxidation inhibitor 0.1~1
Filler 0~35.
Used fire retardant is a halogenated flame retardant, comprises TDE, tribromophenol, dibromophenol, tetrabromo-bisphenol, tetrabromobisphenol A carbonic ester oligopolymer, brominated epoxy resin, poly-bromostyrene, Brominated Polystyrene and multipolymer thereof.
The flame retardant polyester and the alloy plastic thereof of the present invention's preparation have following premium properties:
1. good processing stability
Because antimonous oxide causes the polyester material degraded to a certain extent, molten finger becomes big; As the standard of weighing stability, survey melting index with melting index through several minutes extruding pelletizations; Reaching under the situation of identical flame retardant effect, the melting index of not using antimony trioxide synergist is obviously than having used the big of this synergistic agent, this explanation antimony trioxide synergist can effectively reduce the addition of antimonous oxide, keep identical flame retardant effect, played preventing the purpose of degrading to a certain extent again.
2. flame retardant resistance
The flame retardant resistance of this flame retardant plastics adopts the test of UL94 combustion experiment method.The antimony trioxide synergist that the present invention finds is under the situation that replaces the 0-60% antimonous oxide, still keep the V-0 level, the secondary after flame time of every sample all is no more than 5 seconds, is not with sample and burns the standard lines place, the dropping that does not cause absorbent cotton to catch fire.
3. excellent comprehensive performances
Flame retardant polyester plastics of the present invention and alloy thereof, because antimony trioxide synergist partly replaces antimonous oxide, reduced the risk that antimonous oxide makes polyester degrade in the course of processing, be in a ratio of the flame retardant polyester plastic agent alloy that uses this synergistic agent, tensile strength, flexural strength, shock strength all improves.
4. low-cost
Because this antimony trioxide synergist price is low, generally has only 1/3 to 1/2 of antimonous oxide, substituting antimonous oxide with its part has no small cost advantage.
The synergistic agent of antimonous oxide provided by the present invention can effectively reduce the addition of antimonous oxide in flame retardant polyester and alloy thereof, reduce the risk that antimonous oxide may make the polyester material degraded, the excellent flame retardancy that keeps material, owing to this synergistic agent low price, can reduce the fire-retardant cost of material simultaneously.
