This flame-retardant reinforced PBT composition, by adding fire retardant and fire retarding synergist, enhances the flame retardant resistance of PBT resin.Relative to pure PBT resin, this flame-retardant reinforced PBT composition has stronger flame retardant resistance.
Embodiment
Mainly in conjunction with specific embodiments flame-retardant reinforced PBT composition is described in further detail below.
The flame-retardant reinforced PBT composition of one embodiment, comprises following component according to massfraction: the PBT resin of 100 parts ~ 110 parts, the glass fibre of 50 parts ~ 60 parts, the fire retardant of 10 parts ~ 20 parts, the fire retarding synergist of 5 parts ~ 10 parts, the toughner of 2 parts ~ 6 parts and the auxiliary agent of 0.5 ~ 1 part.
PBT resin is one of the most tough and tensile engineering thermoplastic material, and PBT resin is those semi-crystalline materials, has extraordinary chemical stability, physical strength, electrical insulation characteristics and thermostability, has good stability under very wide envrionment conditions.
In present embodiment, PBT resin is particulate state.
Glass fibre is for strengthening the mechanical property of PBT resin.
In present embodiment, glass fibre is alkali free glass fibre.Alkali free glass fibre is compared medium-alkali glass fibre and is not only had more high strength, in environmental protection also advantageously.
Fire retardant can be added by mechanical mix techniques, makes flame-retardant reinforced PBT composition have flame retardant resistance.
In present embodiment, fire retardant is selected from least one in TDE and brominated epoxy resin.TDE can make the PBT resin of original flame retardant properties difference reach higher flame retardant resistance.
Fire retarding synergist plays coordinate performance, improves the effect of flame retardant effect.
In present embodiment, fire retarding synergist is selected from least one in antimonous oxide and antimony peroxide.Antimonous oxide and TDE (or brominated epoxy resin) are with the use of reaching better flame retardant resistance.
Toughner refers to can increase the flexible material of sizing agent rete.
In present embodiment, toughner is selected from least one in ethylene-acrylate-glycidyl methacrylate (8900) and vinylformic acid bifunctional glyceride polymkeric substance (B-02).Ethylene-acrylate-glycidyl methacrylate (8900) can improve the toughness of flame-retardant reinforced PBT composition, makes flame-retardant reinforced PBT composition can not be too crisp.
In addition, in order to change the color of above-mentioned flame-retardant reinforced PBT composition, the black race of 1 part ~ 3 parts can also be added wherein.
In present embodiment, black race is Cabot black race.
Auxiliary agent is selected from least one in oxidation inhibitor and lubricant.
Oxidation inhibitor is selected from two [4-(1,1,3,3 tetramethyl butyl benzene)] amine (MC-01) and three (2,4-di-tert-butyl-phenyl) at least one in phosphorous acid ester (168), lubricant is selected from least one in ethylenebisstearamide (EBS) and polyethylene wax (PE wax).
MC-01 can improve the oxidation-resistance of flame-retardant reinforced PBT composition, thus improves the work-ing life of flame-retardant reinforced PBT composition.
EBS can improve the oilness of flame-retardant reinforced PBT composition, thus when injection moulding, is not easy sticking mould.
This flame-retardant reinforced PBT composition, by adding fire retardant and fire retarding synergist, enhances the flame retardant resistance of PBT resin.Relative to pure PBT resin, this flame-retardant reinforced PBT composition has stronger flame retardant resistance.
