Table 3
Table 4
From comparative example 2,3,6, can find out, in toughness reinforcing component, the toughening effect that it is main be unsaturated acid anhydride graft polyolefin elastomerics; During single use polyolefine, its toughening effect is also not obvious.From embodiment 1 ~ 14, can find out that toughness reinforcing component accounts for 15 ~ 30 weight parts, and saturated acid anhydride-grafted polyolefin elastomerics and polyolefinic weight ratio be while being 1:4 ~ 4:1, the toughness of nylon 6 moulding compounds increases, and keeps certain rigidity.From embodiment 2 ~ 4, embodiment 6 ~ 17, can find out, especially when saturated acid anhydride-grafted polyolefin elastomerics and polyolefinic weight ratio are between 2:3 ~ 3:2 time, the toughness of material increases more obviously, and rigidity keeps better, realize better the rigidity-toughness balanced of elastomer toughened nylon 610 moulding compounds.
The component concentration of the NYLON610 resin of embodiment 1 ~ 5 is constant, the weight ratio of NYLON610 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 NYLON610 moulding compound increases, and the rigidity of NYLON610 moulding compound improves.Embodiment 1 ~ 5 is known with comparative example 1 ~ 2 contrast, POE-g-MAH and HDPE coordination plasticizing nylon 6, part HDPE replaces toughened Nylon 6 10 moulding compounds prepared by POE-g-MAH and has higher modulus in flexure than only take the NYLON610 moulding compound that POE-g-MAH prepared as toughner, than only take the NYLON610 moulding compound that HDPE prepared as toughner, has stronger toughness.
In table 2, contrast by embodiment 6 ~ 7 with comparative example 3 ~ 4, the contrast of embodiment 8 ~ 9 and comparative example 5 ~ 6, can find out NYLON610 moulding compound prepared by HDPE and POE-g-MAH coordination plasticizing PA610, the NYLON610 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 10, uses HDPE and POE-g-MAH coordination plasticizing NYLON610, when increasing NYLON610 moulding compound toughness, the rigidity of NYLON610 moulding compound is also increased.
Embodiment 15 ~ 18 and comparative example 7 ~ 9 in table 4, the weight ratio of NYLON610 resin and toughness reinforcing component is 77:30, and other components are identical.In embodiment 15 ~ 17 between POE-g-MAH and weight ratio 2:3 ~ 3:2 of HDPE; In embodiment 18, the weight ratio of POE-g-MAH and HDPE is 11:4, and downward trend appears in its rigidity, and when the weight ratio of POE-g-MAH and HDPE becomes 5:1 (comparative example 7), remarkable decline all appears in the rigidity of the moulding compound obtaining and impact property; In comparative example 8 and comparative example 9, the weight ratio of POE-g-MAH and HDPE is less than 1:4; Can find out, now sharply declining appears in the toughness of product.From embodiment 15 ~ 17, compare with embodiment 18, also can find out, when the weight ratio of POE-g-MAH and HDPE is 2:3 ~ 3:2, NYLON610 moulding compound, in toughness reinforcing, is also keeping higher rigidity.
Contriver finds, the present invention is by regulating unsaturated acid or unsaturated acid anhydride graft polyolefin elastomerics and polyolefine to make product reach the performance of rigidity-toughness balanced, but not all nylon is all suitable for, as PA66, although obtain high erosion-resisting characteristics while using POE-g-MAH separately, but intensity can significantly reduce, if use separately HDPE, there is no toughness reinforcing effect.Adopting being mixed of POE-g-MAH and HDPE, along with the addition of POE-g-MAH declines and occurs declining, there is not toughness reinforcing effect in the erosion-resisting characteristics of product.Therefore, even if control the effect that the ratio of unsaturated acid or unsaturated acid anhydride graft polyolefin elastomerics and polyolefin blend can not have rigidity-toughness balanced.
