Description
Technical field
The present invention relates to a kind of super toughness nylon resin and preparation method thereof.
Background technology
Nylon resin is the engineering plastics of developing the earliest, and it has tough and tensile, wear-resisting, anti-solvent, oil resistant, melt viscosity is low, raw material is easy to obtain, recyclable and cost performance advantages of higher.But there are some shortcomings in nylon, as has very strong notch sensitivity, and brittle rupture takes place when jagged, poor, the easy fracture of low-temperature flexibility, and by often occurring the not high phenomenon of glossiness behind the toughening modifying again, this has limited the range of application of nylon greatly.Therefore, the exploitation nylon that not only had super threading property but also had a good gloss degree becomes the direction of development.
At present, the technology of preparation high gloss super toughness nylon resin is not found relevant report.Mainly concentrate on the exploitation of super-toughened nylon for this type of exploitation, the main mode that adopts can be divided into physically modified and chemical modification two big classes, comprises grafts blending, elastic body toughening, receives and be confused polymer toughening, crosslinked toughness reinforcing etc.
The method for preparing high strength ultra tough nylon alloy has been introduced by Beijing University of Chemical Technology in the CN1510084 patent, utilization " nuclear-shell " type multipolymer is as anti-impact modifier, the polymkeric substance that adopts band high reactivity reactive functional group to close simultaneously is an expanding material, prepare the blend alloy material that each component has good consistency and dispersing uniformity, and make alloy material except having all good characteristics of nylon, also have outstanding toughness, low-temperature impact-resistant performance, cold flexibility, chemical resistant properties, environment resistant and lower water-absorbent.Yueyang Petrochemical Plant, Baling Petrochemical Corp has been introduced process for preparing nylon with high rigidity, super toughness and high resistance to low temp in the CN1353141 patent, this method is a base-material with PA6, PA66, make compound compatilizer with EVA/PE-g-MAH, by producing nylon alloy with toughner blend such as EAA, EVA, PE.Super-toughened nylon and preparation method thereof has been introduced in the CN1445278 patent by Shanghai Communications University, prepares nylon/polyolefin elastomerics super-toughened nylon by dynamic vulcanization maleic anhydride graft polyolefin elastomer.The high strength ultra tough nylon alloy of ageing resistance by ultraviolet light has been introduced by Zhuzhou Times new materials Science Co., Ltd in the CN1727407 patent, in nylon resin, be that the polymkeric substance of main toughner, band oxygen functional group is secondary toughner, adds compound ultraviolet light auxiliary agent and oxidation inhibitor simultaneously by adding polymkeric substance that an amount of band high reaction activity official can close, improve the over-all properties of nylon resin, make alloy material have the aging and good mechanical strength of excellent in resistance low-temperature impact, ultraviolet resistance.Chen Zhicheng, Sun Shulin etc. have been delivered " research of ABS-g-MAH toughened polyamide 6 " article in " Chinese plastics " 2007 the 21st the 3rd phases of volume, adopt acrylonitrile-butadiene-styrene copolymer (ABS) and maleic anhydride (MAH) grafting with nucleocapsid structure to carry out toughness reinforcing to polyamide 6 (PA6).
Summary of the invention
The objective of the invention is to raising, a kind of high gloss super toughness nylon resin is provided,, make product can satisfy the use range of requirements at the higher level improving further its glossiness that improves on the flexible basis at super-toughened nylon performance and product appearance requirement.
Another object of the present invention provides the preparation method of high gloss super-toughened nylon.
Technical scheme of the present invention is as follows: the high gloss super toughness nylon resin, by comprising that weight percent is 65 ~ 85% nylon 6 or nylon 66, the vinyl elastomerics of 10 ~ 25% maleic anhydride graft, 1 ~ 7% maleic anhydride graft acrylonitrile-butadiene-styrene copolymer (ABS-g-MAH), 1 ~ 8% acrylonitritrile-styrene resin (AS), other auxiliary agent of 1 ~ 3% is formed.
Above-mentioned nylon resin is nylon 66 (PA66) and nylon 6 (PA6), different for nylon component size and distribution, the viscosity difference is bigger, viscosity scope having between 2.2 ~ 4.5, consider and do glossiness and all reasonable nylon of toughness, in composition, select the PA66 or the PA6 of 2.7 viscositys; Nylon is easy to suction, before use will be in 90 ~ 110 ℃ drying hopper dry 3 ~ 4 hours.Part by weight in whole composition is 65 ~ 85% for PA66 or PA6, is preferably 70 ~ 80%.
The consistency of above-mentioned maleic anhydride graft acrylonitrile-butadiene-styrene copolymer and acrylonitritrile-styrene resin (AS).The ratio of vinyl elastomerics in whole composition of maleic anhydride graft is 10 ~ 25%, and best ratio is 17 ~ 23%.
Above-mentioned maleic anhydride graft acrylonitrile-butadiene-styrene copolymer (ABS-g-MAH), percentage of grafting is 1.1%, in this system, mainly utilize the nucleocapsid structure of acrylonitrile-butadiene-styrene copolymer (ABS), keep favorable rigidity simultaneously at the raising flexible; ABS has good glossiness again, and its grafts has also guaranteed the glossiness of resin in toughness reinforcing; Because of it has vinyl cyanide and styrene group, guaranteed the consistency of acrylonitritrile-styrene resin (AS) in whole system.ABS-g-MAH ratio in whole composition is 1 ~ 7%, and preferably ratio is 3 ~ 5%.
Above-mentioned acrylonitritrile-styrene resin (AS) has the differentiation of the blue end, the yellow end and white background on color, in order to guarantee good color, select the AS of white background here, utilizes AS can form nucleocapsid structure to guarantee toughness in elastomerics; Make full use of the good glossiness of AS simultaneously, make it in super-toughened nylon, improve glossiness.AS ratio in whole composition is 1 ~ 8%, and preferably ratio is 3 ~ 5%.
Other auxiliary agent of above-mentioned 1 ~ 3% mainly is 0.5 ~ 2% organo-silicic oil, the nucleator about 0.1-0.4%, the oxidation inhibitor about 0.2-0.5% and thermo-stabilizer.
The preparation method of above-mentioned materials is as follows: nylon in 90 ~ 110 ℃ drying hopper dry 3 ~ 4 hours, nylon with formula ratio, the vinyl elastomerics of maleic anhydride graft, maleic anhydride graft acrylonitrile-butadiene-styrene copolymer (ABS-g-MAH), acrylonitritrile-styrene resin (AS), after various auxiliary agents mix in the high-speed stirring bucket, from the batch mixing mouth, join temperature and be set at 230 ℃ ~ 290 ℃, length-to-diameter ratio (L/D) is 36: 1 ~ 48: 1 a screw combinations, by in the twin screw extruder of process stipulation, vacuumize granulation and make the high gloss super toughness nylon resin.
