The various embodiments described above all can make nylon 612 moulding compound.From embodiment 1-14, can find out that toughness reinforcing component accounts for 15-30 weight part, and the weight ratio of toughness reinforcing component (A) and toughness reinforcing component (B) is while being 1:4-4:1, the toughness of nylon 612 moulding compound increases, and keeps certain rigidity.From embodiment 2-4, embodiment 6-17, can find out, especially when the weight ratio of toughness reinforcing component (A) and toughness reinforcing component (B) is 2:3-3:2, when the toughness of material increases, keep relatively better rigidity, realized the rigidity-toughness balanced of elastomer toughened nylon 612.
The component concentration of the nylon 612 resin of embodiment 1-5 is constant, the weight ratio of nylon 612 resin and toughness reinforcing component is 80/20, along with the raising of HDPE content in toughness reinforcing component, the parameter socle girder notched Izod impact strength of exosyndrome material toughness first increases gradually as can be seen from Table 1, then declines; Along with the raising of HDPE content in toughness reinforcing component, the modulus in flexure of nylon 612 moulding compound increases, and the rigidity of nylon 612 moulding compound improves.Embodiment 1-5 and comparative example 1-2 contrast are known, POE-g-MAH and HDPE coordination plasticizing nylon 612, part HDPE replaces toughened Nylon 6 12 moulding compounds prepared by POE-g-MAH and has higher modulus in flexure than only take the nylon 612 moulding compound that POE-g-MAH prepared as toughner, than only take the NYLON610 moulding compound that HDPE prepared as toughner, has stronger toughness.
Embodiment 6-7 and comparative example 3-4 contrast in table 2, embodiment 8-9 and comparative example 5-6 contrast, can find out nylon 612 moulding compound prepared by HDPE and POE-g-MAH coordination plasticizing PA612, the nylon 612 moulding compound toughness reinforcing with POE-g-MAH only compared to be had higher socle girder breach and rushes intensity and modulus in flexure; Explanation is compared with POE-g-MAH toughened Nylon 6 12, uses HDPE and POE-g-MAH coordination plasticizing nylon 612, when increasing nylon 612 moulding compound toughness, the rigidity of nylon 612 moulding compound is also increased.
In table 3, in embodiment 10-14, toughness reinforcing component (B) polyolefine of employing different amounts and toughness reinforcing component (A) unsaturated acid graft polyolefin elastomerics carry out toughness reinforcing, when nylon 612 moulding compound toughness improves, also keep higher rigidity.
In table 4, in embodiment 15-17 and comparative example 7-10, the weight ratio of nylon 612 resin and toughness reinforcing component is 77/30, and other components are identical.In embodiment 15-17, the weight ratio of POE-g-MAH and HDPE is between 1:4-4:1, especially between 2:3-3:2; In comparative example 7-8, the weight ratio of POE-g-MAH and HDPE is greater than 4:1; In comparative example 9-10, the weight ratio of POE-g-MAH and HDPE is less than 1:4.Embodiment 15-17 and comparative example 7-8 contrast, and can find out the good toughness of the nylon 612 moulding compound in comparative example 7-8, but rigidity are poor; Embodiment 15-17 and comparative example 9-10 contrast, and can find out that the rigidity of the nylon 612 moulding compound in comparative example 9-10 keeps better, but toughening effect are poor.Therefore, from embodiment 15-17 contrast comparative example 7-10, can find out that the weight ratio of working as POE-g-MAH and HDPE is between 1:4-4:1, especially, between 2:3-3:2, nylon 612 moulding compound, in toughness reinforcing, is also keeping higher rigidity.
Nylon 612 moulding compound of the present invention, add toughness reinforcing component (A) unsaturated acid graft polyolefin elastomerics and toughness reinforcing component (B) polyolefin component to carry out toughness reinforcing, and (A) component is 1:4-4:1 with (B) weight ratio of component, in toughened Nylon 6 12, keep the rigidity of nylon 612 also relatively better.Especially when (A) component is when (B) weight ratio of component is 2:3-3:2, when toughened Nylon 6 12 has higher toughness, also keeping higher rigidity.
