Table 3
Table 4
As can be seen from comparative example 2,3,6, in toughening element, its main toughening effect be unsaturated acid anhydride grafted polyolefin olefin elastomer; During single use polyolefine, its toughening effect is also not obvious.Can find out that toughening element accounts for 15 ~ 30 weight parts from embodiment 1 ~ 14, and when saturated acid anhydride-grafted polyolefin elastomerics and polyolefinic weight ratio are 1:4 ~ 4:1, the toughness of nylon 6 moulding compound increases, and keeps certain rigidity.As can be seen from embodiment 2 ~ 4, embodiment 6 ~ 17, especially when saturated acid anhydride-grafted polyolefin elastomerics and polyolefinic weight ratio are between 2:3 ~ 3:2, the toughness of material increases more obvious, and rigidity keeps better, realize the rigidity-toughness balanced of elastomer toughened nylon 610 moulding compound better.
The component concentration of the NYLON610 resin of embodiment 1 ~ 5 is constant, the weight ratio of NYLON610 resin and toughening element is 80:20, as can be seen from Table 1 along with the raising of HDPE content in toughening element, the parameter Izod notched impact strength of exosyndrome material toughness first increases gradually, then declines; Along with the raising of HDPE content in toughening element, the modulus in flexure of NYLON610 moulding compound increases, and the rigidity of NYLON610 moulding compound improves.Embodiment 1 ~ 5 and comparative example 1 ~ 2 contrast known, POE-g-MAH and HDPE coordination plasticizing nylon 6, it is that NYLON610 moulding compound prepared by toughner has higher modulus in flexure with POE-g-MAH than only that part HDPE replaces toughened Nylon 6 10 moulding compound prepared of POE-g-MAH, than being only that NYLON610 moulding compound prepared by toughner has stronger toughness with HDPE.
In table 2, by the contrast of embodiment 6 ~ 7 with comparative example 3 ~ 4, the contrast of embodiment 8 ~ 9 and comparative example 5 ~ 6, NYLON610 moulding compound prepared by HDPE and POE-g-MAH coordination plasticizing PA610 can be found out, compared with the NYLON610 moulding compound that only POE-g-MAH is toughness reinforcing, there is higher socle girder breach and rush intensity and modulus in flexure.Illustrate compared with POE-g-MAH toughened Nylon 6 10, use HDPE and POE-g-MAH coordination plasticizing NYLON610, while increase 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 toughening element is 77:30, and other components are identical.In embodiment 15 ~ 17 POE-g-MAH and HDPE weight ratio 2:3 ~ 3:2 between; 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 obtained 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 compared 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 while toughness reinforcing, also remain higher rigidity.
Contriver finds, the present invention makes product reach the performance of rigidity-toughness balanced by regulating unsaturated acid or unsaturated acid anhydride grafted polyolefin olefin elastomer and polyolefine, but it is not all applicable to all nylon, as PA66, although obtain high erosion-resisting characteristics when being used alone POE-g-MAH, but intensity can significantly reduce, if be used alone HDPE, does not then have toughness reinforcing effect.Adopt the mixture of POE-g-MAH and HDPE, the erosion-resisting characteristics of product declines and appearance decline along with the addition of POE-g-MAH, there is not toughness reinforcing effect.Therefore, even if the ratio controlling unsaturated acid or unsaturated acid anhydride grafted polyolefin olefin elastomer and polyolefin blend can not have the effect of rigidity-toughness balanced.
