Description
Technical field
The present invention relates to a kind of ABS material with excellent light aging resisting property and preparation method thereof, belong to polymer modification and manufacture field.
Background technology
ABS resin is due to its workability, and impact resistance and excellent dimensional stability, ABS part can carry out the secondary processing such as metallize, plating, welding, and it can be widely used in the fields such as electronic instrument, household electrical appliance and automobile decoration piece.ABS resin exists due to the double bond of polyhutadiene, easily occurs agingly to cause degradation, the problems such as goods generation xanthochromia under the effect of light and heat, so need to add a certain amount of photostabilizer and oxidation inhibitor to improve its stability.Most photostabilizer is all the organic compound or oligopolymer that molecular weight is lower.When these photostabilizer additions are larger, under high temperature or UV-irradiation, photostabilizer is easy to separate out to surface, and " frostization " problem occurs.
Xylogen extensively exists as one, reproducible valuable source, has important development prospect preparing in degradable, reproducible polymer composite.The existing bibliographical information of xylogen in heat oxygen aging resistance and light aging resisting at present, as PolymerDegradationandStability, 2003, (81), 9 ~ 18 have studied 15 kinds of xylogen for polyacrylic ageing resistance; PolymerJournal, 2005, (37) 8,633 ~ 635 research xylogen are as mechanics performance comparison before and after uv-resistant aging dose of illumination ageing of PP and PE material.
Patent CN101210097A is by incident precipitation problem under adding the molecular sieve with adsorptive power and improving ABS resin illumination condition; Patent CN102030965A improves by the N-phenylmaleimide and compatilizer etc. adding high rigidity the precipitation problem that toner and auxiliary agent cause under light, heat condition.But these method light aging resisting limited efficiency, therefore develop a kind of ABS material with excellent light aging resisting property and extremely have realistic meaning.
Summary of the invention
The object of the present invention is to provide a kind of ABS material with excellent light aging resisting property and preparation method thereof, obtained ABS material has good anti-precipitation and anti-yellowing change ability.
The object of the invention is to be achieved through the following technical solutions.
There is an ABS material for excellent light aging resisting property, be made up of the raw material of following weight percents meter:
Wherein said ABS is the ABS that continuous bulk polymerization method is produced, wherein rubber content: 5 ~ 30%.
Described xylogen is wood pulp xylogen, without any modification.
Described ABS-g-MAH percentage of grafting is 1 ~ 1.5%.
Described photostabilizer is hindered amine light stabilizer 944.
Described oxidation inhibitor comprises primary antioxidant and auxiliary anti-oxidant, and primary antioxidant is the one or more combination thing in 1010,3114 and 1076; Described auxiliary anti-oxidant is one or both compositions in 168 and 618.
Other described additive is the auxiliary agent such as various toner additive or Masterbatch, sorbent material, fire retardant or static inhibitor.
A kind of preparation method with the ABS material of excellent light aging resisting property described above is as follows:
(1) raw material is taken by weight ratio;
(2) various raw material and additive are mixed 5 ~ 15 minutes in super mixer;
(3) mixed raw material is added in twin screw extruder, cooling granulation after melt extruding, obtained ABS material, its technique is: 220 ~ 230 DEG C, a district, two 230 ~ 240 DEG C, districts, three 230 ~ 240 DEG C, districts, four 215 ~ 225 DEG C, districts, the residence time of whole extrusion is 1 ~ 2 minute, and pressure is 8 ~ 10MPa.
Advantage of the present invention is:
1, the present invention uses xylogen partly or entirely can substitute traditional photostabilizer, can effectively reduce ABS surface and separate out and xanthochromia problem;
2, the ABS material production technique prepared of the present invention is simple, and cost is low, easy industrialization.
Embodiment
Technical characterstic of the present invention is set forth further below in conjunction with specific embodiment.
In embodiment and comparative example A BS material prescription, the XR-409H that ABS used selects LG company to produce.Xylogen used is wood pulp xylogen, without any modification, and self-control.ABS-g-MAH is system, percentage of grafting 1%.Photostabilizer select Ciba company to produce 944.The Irganox1010 that primary antioxidant selects Ciba company to produce.The Irganos168 that auxiliary anti-oxidant selects Ciba company to produce.
Various raw material and additive are dry mixed 5 ~ 15 minutes in super mixer; The raw material mixed is added in twin screw extruder, through melt extruding, cooling granulation obtains ABS material, its technique is: 220 ~ 230 DEG C, a district, two 230 ~ 240 DEG C, districts, three 230 ~ 240 DEG C, districts, four 215 ~ 225 DEG C, districts, the residence time of whole extrusion is 1 ~ 2 minute, and pressure is 8 ~ 10MPa.
performance evaluation mode and the standard of implementation
The particulate material prepared by aforesaid method, in the convection oven of 90 ~ 100 DEG C, drying 3 ~ 4 hours, then carries out shaping sample preparation by dried particle on injection moulding machine.
Tensile property is tested: undertaken by ISO527-2 standard, specimen size is 170*10*4mm, and draw speed is 50mm/min.
Bending property is tested: undertaken by ISO178 standard, specimen size is 80*10*4mm, and rate of bending is 2mm/min, and span is 64mm, and modulus in flexure is undertaken by tangential direction.
Simply supported beam notched Izod impact strength is tested: undertaken by ISO179 standard, specimen size is 80*10*4mm, and notch depth is 1/3rd of sample thickness.
Illumination ageing test is according to test: specify according to standard P V1303 standard, carry out 5 cycles and 10 periodic tests respectively, after periodicity of illumination terminates, pass judgment on rating for light fastness according to the scale △ E changed before and after material surface color, be specifically divided into 5 grades: △ E=0 ± 0.2 to be 5 grades; △ E=0.8 ± 0.2 is 4.5 grades; △ E=2.5 ± 0.35 is 3.5 grades; △ E=3.4 ± 0.4 is 3 grades; △ E=4.8 ± 0.5 is 2.5 grades; △ E=6.8 ± 0.6 is 2 grades; △ E=9.6 ± 0.7 is 1.5 grades; △ E=13.6 ± 1.0 are 1 grade; △ E numerical value is less, represents that the light aging resisting property of material is better.
The formula of embodiment and comparative example and properties test result are shown in lower each table:
Table 1 embodiment 1 ~ 5 and comparative example 1 ~ 3 material prescription table (% by weight)
Table 2 embodiment 1 ~ 5 and comparative example 1 ~ 3 test result
Can find that the xylogen of content 3% just can make the light aging resisting property of ABS material reach the higher level of 4.5 grades from embodiment 1 ~ 5 and the contrast of comparative example 1 ~ 3, simultaneously the good mechanical property of still maintenance of ABS material.And ABS material to be made to reach 4 grades or higher level iff the traditional organic photostabilizer of use, the consumption of photostabilizer just must add exponentially, under long-time high temperature and light conditions, photostabilizer is also easy to precipitate into sample surface and forms " bloom " phenomenon.And when material reaches the overlength illumination in 10 cycles time, use xylogen just more obvious as the formula advantage of light aging resisting auxiliary agent, make ABS material have more long-acting light aging resisting ability.
