Description
Technical field
The present invention relates to technical field of polymer materials, it is related to a kind of material suitable for automotive upholstery and its preparation side
Method, and in particular to there is the dark heat-proof ABS resin composition for improving weatherability to be a kind of.
Background technology
Acrylonitrile-butadiene-styrene terpolymer (ABS) is a kind of high gloss, it is resistant to chemical etching, high it is heat-resisting,
The engineering plastics of the high comprehensive performances such as easy processing, superior dimensional stability, in electric, automobile, household electrical appliance, office etc.
Field has a wide range of applications.Wherein heat-proof ABS is the most universal in the application of automotive field, especially automobile door plate, secondary instrument
Disk, sunshading board, saucer, glove box, catch etc. have certain requirements inside gadget to heat resistance.In addition, heat-proof ABS can also be applied
In the exterior trim such as rearview mirror, grid, license plate, taillight field.
The heat-proof ABS applied as automotive trim is most important also resistance in addition to the requirement such as gloss, VOC, mechanical strength
The requirement of light aging.With flowing for the dark interior trim especially black interior trim for the embodiment sports style that depth is liked by young consumers
OK, the weatherability to black ABS resin also just proposes very high requirement.
As a rule, black ABS weatherability is better than cream-coloured, palm fibre due to carbon black to the absorption and shielding action of ultraviolet
This kind of light ABS resin of color, grey.When being exposed to the sun out of doors, also typically black ABS light fastness aging behaves oneself best.But
It is black in some automotive trim weathering protocols with very high blackboard temperature such as SAE J2412, masses PV1303 weather-proof test
Color ABS resin is difficult often by this kind of weather resistant experiment.Show as the dark ABS products dermatoglyph with dermatoglyph surface texture after illumination
Lose, shinny, blackening causes declining to a great extent for color fastness.As the carbon black of conventional black pigments have very high coloring and
Light absorptive, so the easily extinction yield heat under the irradiation of natural sunshine and the conventional xenon arc lamp of artificial accelerated aging, leads
Surface temperature increase is caused, black material even can be higher by more than 30 DEG C than equal white material surface temperature.So in blackboard
Temperature reaches 100 DEG C of popular PV1303 weather resistant experiments standard, and ABS surface temperature is even up to more than 100 DEG C, black ABS
L values can often decline more than 5 units after the illumination in 5 cycles, the glossiness in dermatoglyph face improves more than 100% so that
3 grades are typically smaller than in color fastness.And equal times or irradiation energy of the dark ABS of same material in SAE J2412 weathering protocols
After the suitable illumination of amount, the decline of L values can be within 1.Weather-proof in high temperature of visible black color ABS resin drastically deteriorates, and this
The deterioration of a little photooxidation aging properties is can not to be realized by simply increasing the content of light stabilizer.
Infrared reflecting paint is inorganic pigment, by metal oxide, and nitrate, acetate, or even oxide are passed through after mixing
Metal ion and oxonium ion in reaction, raw material takes place again in the calcining of 1000 DEG C of high temperature above, reaction, raw material solid in itself
Arrangement, formed it is more stable be similar to spinel structure or Rutile structure, a part of infrared light can be reflected.Such as BASF
(infrared reflecting paint of triumphant one hundred) and Shepherd (Xue Te) company is too by (BASF), Clariant (Clariant), Heubach
Sunlight reflectivity (TSR) is general 25~40%.
In addition, the content of increase heat-resistant agent, dark ABS shinny changes after light aging can be improved by improving ABS heat resistance
Black the problem of, improve weatherability.But typically heat-resistant agent is not high to the efficiency of ABS heat-resisting raising, the even resistance to thermal efficiency
Highest N-PMI-St-MAH class heat-resistant agents need for more large content of addition, so can cause mobility and impact strength
Deteriorate.
The content of the invention
For the technological deficiency of existing dark heat-proof ABS weatherability difference, having it is an object of the invention to provide one kind improves
The dark heat-proof ABS resin composition of weatherability, so as to solve it is above-mentioned prepare dark heat-resisting ABS resin in the prior art when exist
Mechanical property deteriorate, the problems such as weatherability is bad.
In the ABS resin system of the present invention, using the compound scheme in infrared emission pigment and a small amount of titanium dioxide, it must
The purpose of the present invention must could be realized by upgrading while both sides technology path, i.e., on the one hand, reduction as much as possible is set
Fat surface temperature is to reduce the required amount of heat-resistant agent, so that ensure that mechanical property loss is reduced to minimum level, specifically,
The surface temperature of ABS resin product in photo aging process can be reduced by infrared reflecting paint, improves dermatoglyph and loses, send out
Bright the problem of, and because the tinting strength, tinting power of infrared reflecting paint is relatively low, to caused by the change of illumination front and rear surfaces material
Aberration it is relatively small, so as to reduce overall aberration.On the other hand, the increasing of blackness is offset using titanium dioxide xanthochromia itself is allowed
Plus, so as to ensure color fastness；In the system of the present invention, titanium dioxide is counteracted under L values due to xanthochromia can occur after light aging
Drop, reduces the degree of the overall blackening in surface, is also achieved that the reduction of aberration.The present invention can be reduced by above-mentioned means
For meet ABS weatherabilities and needed for thermal level, that is, mean that the addition of heat-resistant agent, therefore the dark color can be reduced
Heat-proof ABS can have excellent mechanical property and weather resistance simultaneously.Such as it is using the embodiment of reduction resin surface temperature
