The glass-fiber-reinforced black halogen-free flame-retardant polyamide composite material consists of the following raw materials in parts by weight: 60 to 68 parts of polyamide 610 resin, 12 to 17 parts of polyamide 6 resin, 7 to 11 parts of flexibilizer, 8 to 14 parts of flame retardant, 9 to 18 parts of phosphate, 0.5 to 0.9 part of antioxidant, 23 to 29 parts of reinforcing fibers, and 2 to 3 parts of carbon black. Through test, the glass-fiber-reinforced black halogen-free flame-retardant polyamide composite material has the following performance indexes that the tensile strength is greater than 110 to 150MPa, the bending strength is greater than 200 to 220MPa, the notch impact strength of a cantilever beam is greater than 10 to 14kj/m<2>, and the fire resistance reaches V-0(UL-94-1.6mm).
Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of glass fibre enhanced black halogen-free Flameproof polyamide matrix material.
Background technology
Polyamide material is widely used in national economy every field such as automobile, building, electronics, daily electric, small household appliances etc.Owing to can produce a kind of off-odor during the polyamide material burning, and produce certain smog field, again because along with rapid growth of economy, demand to this type of material is continuous growing trend, therefore the urgent aforementioned shortcoming of wishing to remedy polyamide material causes damage to the environment and the person when the burning avoiding
Chinese patent CN101503570A discloses the flame retardant resistance of using halogenous fire retardant to improve goods, and this class material abandons the back or when reclaiming burning disposal, still produce hazardous and noxious substances, the harm environment.Therefore, exploitation has the halogen-free environmental characteristics, has positive effect even be discarded in the polyamide material that also can not discharge hazardous and noxious substances in the environment.
Summary of the invention
Task of the present invention is that a kind of glass fibre enhanced black halogen-free Flameproof polyamide matrix material will be provided, and it has halogen-free flameproof, can not discharge the characteristics of hazardous and noxious substances.
Task of the present invention is finished like this, a kind of glass fibre enhanced black halogen-free Flameproof polyamide matrix material, and its raw material by following parts by weight is formed:
In one embodiment of the invention, described polyamide 6 10 resins be fusing point more than 230 ℃, the limiting viscosity index is 2.4 polyamide 6 10 resins.
In another embodiment of the present invention, described polyamide 6 resin is the polycaprolactam polyimide resin, 210 ℃ of fusing points.
In yet another embodiment of the present invention, described toughner is the ethylene-octene copolymer of maleic anhydride graft, and percentage of grafting is 0.8%.
In another embodiment of the present invention, described fire retardant is a hypo-aluminum orthophosphate.
Also have among the embodiment of the present invention, described phosphoric acid salt is the melamine poly-phosphate.
More of the present invention and among embodiment, described oxidation inhibitor is β (3,5-di-t-butyl-4-hydroxybenzene) propionic acid octadecanol ester.
In of the present invention and then embodiment, described fortifying fibre is the alkali-free short glass fiber of length 3mm.
Of the present invention again more and among embodiment, described carbon black is a thermally oxidized black.
