Description
Technical field
The present invention relates to a kind of fast light thermal resistance retardant polyamide 6 and its preparation method and application.
Background technology
Polymeric amide (Polyamide, be called for short PA, be commonly called as nylon) be a kind of engineering plastics of widespread use, current PA has become the class that in five large-engineering plastics, output is maximum, most widely used, kind is maximum, it is various in style, have PA6, PA66, PA11, PA12, PA46, PA610, PA612, PA1010 etc., wherein PA6 and PA66 is the maximum two kinds of polyamide materials of consumption.
Related data shows that the share of polyamide 6 and polyamide 66 two kinds of polymeric amide in world market in 2009 is about 5,500,000 tons, wherein 2/3 be mainly used in producd fibers, and other 1/3 for converting engineering plastics (polyamide blended material) to, can find out that polyamide 6 and polyamide 66 are the important polymer in global project plastics market thus, within 2008, account for 28% of global project plastics, be only second to 34% of polycarbonate.And polyamide 6 and polyamide 66 topmost consumption place are automobile and electric industry, according to related data, account for 44% and 27% respectively at the automobile in Europe in 2010 and the polymeric amide of electric and electronic industrial consumption, other mainly consume place is construction industry and package plant.Due to 2008, Japanese economy was subject to global financial crisis impact; significantly declining has appearred in polyamide resin output; but along with decorporating of financial crisis; in Japan polyamide resin demand starts progressively to increase; the output of Japanese polyamide resin in 2009 is 550,000 tons, accounts for 29% of whole engineering plastics output.The constituent ratio in its each field is: automotive field is 37%, and electric field 23%, film packaging is 30%, and other are about 10%.But the tsunami caused by earthquake in 2011, its economy is inflicted heavy losses on again, but a high-tide period after low tide one, must be had. also can increase the demand of polymeric amide.
Polyamide material has stronger polarity due to the amide group contained in its structure, is easily subject to the impact of the environmental factorss such as high temperature, ultraviolet, moisture, and the reactions such as macromolecular chain generation is crosslinked, fracture, isomerization, cause material property deterioration.
Correlative study shows, polymeric amide topmost degraded mode under air or sunlight is photooxidation droping.Photooxidation droping will be caused when it is exposed under wavelength is greater than the illumination of 290nm, and photooxidation droping carries out with free radical autoxidation course.Because most of product all can have direct contact with light, thus will inevitably have an impact to the stable of its performance.
The process of stabilization of polyamides, mainly long-acting thermally-stabilised and long-acting light is stablized.During processing polymeric amide, look dirt and thermal ageing very easily occur, and generally use phosphorous acid ester to suppress its look dirt or oxidated situation traditionally.Current commercial conventional thermo-stabilizer mainly contains mantoquita, aromatic amine, hindered phenol and hindered amine four class.Mantoquita is normal to be share with halogen compounds or phosphorus compound, but system shortcoming can cause look dirt and easily be extracted by water.Aromatic amine is also effectively stablizer, working concentration high (0.5% ~ 2%), because aromatic amine can cause look dirty, only can be used for dirty less demanding field of checking colors, and also has in recent years to do modification to aromatic amine specific product and use it for light color or without colour product.Hindered phenol does not have the shortcoming of above two classes, especially taking into account in good thermo-oxidative stability, good colour stability and the goods at contact food, hindered phenol becomes first-selected, and working concentration 0.2 ~ 0.7%, and may also can be used as addition type masterbatch in polycondensation process.The working concentration of hindered amine thermo-stabilizer in polymeric amide lower (0.04% ~ 0.1%), add when polyreaction and do not produce look contamination phenomenon, there is good thermostable effect, for the hot fields of Recent study exploitation, hindered amine is that (oxidation inhibitor and photostabilizer are in the application of polymeric amide macromolecular material for the extraordinary heat of a class and photostabilizer, Lin Depei, ageing of plastics and anti-aging technical conferences collection of thesis).
Current polyamide 6 anti-aging mainly by adding composite antioxidant, composite antioxidant also such as such as irgasfos 168 and Irganox1010, Irganox1076 and Cyanox1790 etc., be 0.2% ~ 0.4% for nylon 6 and nylon66 fiber consumption, after processing, yellowness index obviously declines (the Synthesis and application of irgasfos 168, Zhao Ying etc., chemical engineer, in August, 2003).
Although a lot of composite antioxidant can improve the performance of polyamide 6 in thermo oxidative aging process, improvement result is limited, and also also the combination of not all oxidation inhibitor is all improved effect to the performance of polyamide 6.
But, also do not possess the polyamide 6 product of anti-light hot oxygen, fire-retardant, high tensile and weathering resistance at present simultaneously, the improvement of polyamide 6 various aspects of performance is still had much room for improvement.
