Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of environmental protection polyamide alloy material of PET modification.
Background technology
Polymeric amide is obtained by diprotic acid and diamine polycondensation, is a kind of thermoplastics, owing to have the intensity height, and the strong point of Good Heat-resistance, thereby be widely used in fields such as automobile, electronics and material of construction.Polyamide resin has breaking tenacity and the high characteristics of fatigue resistance, but because molecular chain polarity is strong, thereby have the shortcoming of the easy moisture absorption.Because polyethylene terephthalate (PET) has good rigidly, modulus height, advantage that water-intake rate is low, therefore with polyethylene terephthalate and the polyamide blended over-all properties that can improve alloy material, thus the expanded application scope.In addition, novel material is used and is spreaded all over industry and civilian every field, along with abandoning of goods, some heavy metals and objectionable impurities is spread in the environment, and therefore, the feature of environmental protection of material also is the important factor that overlooks either of the two.
In view of this, the polyamide alloy material of developing mechanical physical property excellence and environmental protection has positive effect.
Summary of the invention
Task of the present invention is to provide a kind of environmental protection polyamide alloy material of significantly improving mechanical-physical and being conducive to embody the PET modification of the desirable feature of environmental protection of helping.
Task of the present invention is finished like this, a kind of environmental protection polyamide alloy material of PET modification, and its raw material by following parts by weight is formed:
In one embodiment of the invention, described polyamide 66 resin is that fusing point is at the polyamide 66 resin more than 220 ℃.
In another embodiment of the present invention, described polyamide 6 resin is softening temperature at 210 ℃ polycaprolactam polyimide resin.
In yet another embodiment of the present invention, described PET resin refers to the pet resin of 250 ℃ of fusing points.
In another embodiment of the present invention, described compatilizer is the acrylic resin of maleic anhydride graft.
Also have among the embodiment of the present invention, described fire retardant is hypo-aluminum orthophosphate.
More of the present invention and among embodiment, described filler is the nano-calcium carbonate of median size 80～120 nanometers.
In of the present invention and then embodiment, described oxidation inhibitor is tricresyl phosphite (24-di-tert-butyl-phenyl) ester.
Of the present invention again more and among embodiment, described fortifying fibre is the alkali free glass fibre of length 6mm.
In again of the present invention and then embodiment, described carbon black is the carbon black that channel process is produced.
