At present, the increasing tougheness improving nylon 612 resin mainly adopts elastomerics grafting reactivity group and nylon 612 resin alloy to carry out tenacity increased nylon. But elastomerics and nylon 612 resin alloy, while improving material increasing tougheness, also reduce the rigidity of material, limit the use field of nylon 612 resin to a certain extent.
Summary of the invention
In order to overcome the deficiencies in the prior art and defect, the primary and foremost purpose of the present invention is to provide toughened Nylon 6 12 moulding compound of a kind of high rigidity.
Another object of the present invention is to provide the preparation method of toughened Nylon 6 12 moulding compound of above-mentioned high rigidity.
The present invention is achieved by the following technical solution:
A kind of nylon 612 moulding compound, by weight, comprises following component:
Nylon 612 resin: 70.0 ~ 85.0 parts;
Toughening element: 15.0 ~ 30.0 parts;
Wherein, toughening element comprises following component:
(A) unsaturated acid anhydride graft polyolefin elastomerics;
(B) polyolefine;
Wherein, (A) component is 1:4 ~ 4:1 with the weight ratio of (B) component.
Preferably, a kind of nylon 612 moulding compound, by weight, comprises following component:
Nylon 612 resin: 70.0 ~ 80.0 parts;
Toughening element: 15.0 ~ 30.0 parts;
Wherein, toughening element comprises following component:
(A) unsaturated acid anhydride graft polyolefin elastomerics;
(B) polyolefine;
Wherein, (A) component is 2:3 ~ 3:2 with the weight ratio of (B) component.
Described nylon 612 resin is 1.7 ~ 3.4 according to the relative viscosity that standard ISO 307 is tested; The relative viscosity of nylon 612 resin is more high, and the toughness of nylon 612 moulding compound is corresponding more high, but nylon 612 resin relative viscosity raises, and its processing characteristics also can decline; Take into account the balance of mechanical property and processing characteristics, it is preferable to relative viscosity is the nylon 612 resin of 2.0 ~ 2.8; It is more preferably the nylon 612 resin of relative viscosity 2.1 ~ 2.6.
As nylon 612 resin of the present invention, meeting relative viscosity is that 1.7 ~ 3.4 PA612 resins limited are all applicable, compound as the example of nylon 612 resin of the present invention can be enumerated: Hiprolon90(relative viscosity 2.2, Suzhou writing brush regular senior middle school molecular material); GYEHVN(relative viscosity is 2.4, Shandong Guang Yin novel material company limited) etc.
Described toughening element (A) is maleic anhydride graft terpolymer EP rubber (EPDM-g-MAH) and/or maleic anhydride grafted ethene-octene copolymer (POE-g-MAH); If no special instructions, the EPDM described in following the present invention is terpolymer EP rubber, and described POE is ethylene-octene copolymer.
In described toughening element, the unsaturated acid of (A) component or the percentage of grafting of unsaturated acid anhydride are 0.5% ~ 1.3%, and melt flow rate (MFR) is 0.5 ~ 6.0g/10min; Wherein, percentage of grafting adopts volumetry, makes indicator with phenolphthalein, by acetic acid-xylene solution titration determination. Melt flow rate (MFR) is according to ASTMD1238 test, and test condition is add load 2.16Kg at 190 DEG C.
Described toughening element (B) is selected from one or more mixtures of ultrahigh molecular weight polyethylene(UHMWPE) (UHMWPE), high density polyethylene(HDPE) (HDPE), linear low density polyethylene (LLDPE), Low Density Polyethylene (LDPE); It is preferably one or more mixtures of HDPE, LLDPE, LDPE, it is more preferable to be HDPE.
Described nylon 612 moulding compound, also comprises the processing aid of 0 ~ 0.6 weight part, and described processing aid is selected from one or more mixtures of oxidation inhibitor, lubricant, nucleator.
Described oxidation inhibitor is selected from N, N '-1,6-dihexyl two (3,5-bis-(1,1-dimethyl ethyl)-4-hydroxyl) phenylpropyl alcohol acyl (general oxidation inhibitor 1098 by name), four (��-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid) pentaerythritol ester (general antioxidant 1010 by name), three (2,4-di-tert-butyl-phenyl) one or more mixtures in phosphorous acid ester (general irgasfos 168 by name) or mantoquita composite antioxidant, it is preferable to oxidation inhibitor 1098.

The various embodiments described above all can obtain nylon 612 moulding compound. Can find out that from embodiment 1-14 toughening element accounts for 15-30 weight part, and when the weight ratio of toughening element (A) and toughening element (B) is 1:4-4:1, the toughness of nylon 612 moulding compound increases, and keeps certain rigidity. As can be seen from embodiment 2-4, embodiment 6-17, especially when the weight ratio of toughening element (A) Yu toughening element (B) is 2:3-3:2, while the toughness of material increases, keep relatively better rigidity, it is achieved that the strong and unyielding balance 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 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 nylon 612 moulding compound increases, and the rigidity of nylon 612 moulding compound improves. Embodiment 1-5 and comparative example 1-2 contrast is known, POE-g-MAH and HDPE coordination plasticizing nylon 612, it is that nylon 612 moulding compound prepared by toughner has higher modulus in flexure taking POE-g-MAH than only that part HDPE replaces toughened Nylon 6 12 moulding compound prepared of POE-g-MAH, than being only that NYLON610 moulding compound prepared by toughner has stronger toughness taking HDPE.
Embodiment 6-7 and comparative example 3-4 contrast in table 2, embodiment 8-9 and comparative example 5-6 contrast, nylon 612 moulding compound prepared by HDPE and POE-g-MAH coordination plasticizing PA612 can be found out, compared with increasing tough nylon 612 moulding compound with only POE-g-MAH, there is higher socle girder breach and rush intensity and modulus in flexure; Illustrate compared with POE-g-MAH toughened Nylon 6 12, it may also be useful to HDPE and POE-g-MAH coordination plasticizing nylon 612, while increasing nylon 612 moulding compound toughness, the rigidity of nylon 612 moulding compound is also increased.
In table 3 in embodiment 10-14, it is tough that toughening element (B) polyolefine of employing different amounts and toughening element (A) unsaturated acid graft polyolefin elastomerics carry out increasing, and nylon 612 moulding compound toughness also keeps higher rigidity while improving.
In table 4 in embodiment 15-17 and comparative example 7-10, the weight ratio of nylon 612 resin and toughening element 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 contrasts, it can be seen that the good toughness of the nylon 612 moulding compound in comparative example 7-8, but rigidity is poor; Embodiment 15-17 and comparative example 9-10 contrasts, it can be seen that the rigidity of the nylon 612 moulding compound in comparative example 9-10 keeps better, but toughening effect is poor. Therefore, contrasting from embodiment 15-17 and can find out when the weight ratio of POE-g-MAH and HDPE is between 1:4-4:1 comparative example 7-10, especially between 2:3-3:2, nylon 612 moulding compound, while increasing is tough, also remain higher rigidity.
Nylon 612 moulding compound of the present invention, add toughening element (A) unsaturated acid graft polyolefin elastomerics and toughening element (B) polyolefin component carries out increasing tough, and the weight ratio of (A) component and (B) component is 1:4-4:1, while toughened Nylon 6 12, keep the rigidity of nylon 612 also relatively better. Especially, when the weight ratio of (A) component Yu (B) component is 2:3-3:2, while toughened Nylon 6 12 has higher toughness, also remain higher rigidity.
Every performance test methods:
Izod notched impact strength: test by ISO180/1A, sample is of a size of 80 �� 10 �� 4mm3, notch type A; Modulus in flexure: test by ISO178, sample is of a size of 80 �� 10 �� 4mm3, test speed is 2mm/min.
