The outside drawing of the goth black PC/ABS alloy materials that Fig. 1 is prepared for the present embodiment, as seen from the figure, the resin alloy
Material surface is perfect, and color is goth black, and color table value indicative L of general same type black material is 5-6, but its L value has reached 2,
Give people a kind of enjoyment of U.S..
Fig. 2 is further processed into the outer of product for the goth black PC/ABS alloy materials prepared in the embodiment of the present invention 3
See figure.As seen from the figure, the products appearance being molded is goth black, and surface is smooth and has the same gloss of metal, great aesthetic values.
According to the preparation method of embodiment 3, embodiment 4 and 5 and the PC/ABS alloy materials in comparative example 1-7 are prepared,
The raw material components (mass parts) of each embodiment and comparative example are as shown in table 1.
Table 1
Performance test：
The measure of color table value indicative：It is measured on colour photometer, color table value indicative is L, and L values are less, illustrates that color is got over
Deep (black), the dispersiveness of carbon black are better.
Fluidity testing：Its melt flow rate (MFR) is entered using melt flow rate (MFR) tester by the test method of GB3682
Row is determined, and melt flow rate (MFR) is bigger, and material flowability is better.
The evaluation of surface quality：Surface quality grades are carried out to which according to the standard in table 2 to evaluate, surface quality is got over
It is good, illustrate that the dispersiveness of carbon black is better.
Table 2
Measurement result is as shown in table 3.
Table 3
Understand through contrast：
The melt flow rate (MFR) of the PC/ABS alloy materials obtained in embodiment 3 has reached 27g/10min, color table value indicative
L is 2, and surface quality grades are 1 grade, and very well, color is goth black for its mobility.Embodiment 1 and 2 is by comparison, although component is the same,
But its preparation technology is slightly different, the PC/ABS alloy materials performance which prepares is more weaker than embodiment 3.Equally, implement
Compared with Example 3, preparation technology is although identical for example 4 and 5, but component proportion is different, the PC/ABS alloy materials which obtains
Performance is also not so good as embodiment 3, therefore embodiment 3 for the optimum component proportion of the present invention and preparation technology.
Compared with Example 3, mineral oil, PE waxes and coupling agent are eliminated in comparative example 1, its melt flow rate (MFR) is 14g/
10min, color table value indicative L are 6, and surface quality grades are 4 grades, and properties decline obvious.
Compared with comparative example 1, comparative example 2 adds mineral oil, and its melt flow rate (MFR) increased 7g/10min, color table
Value indicative L reduces 2, and surface quality grades improve 1 grade, illustrates only to add mineral oil to can be good at improving the mobility of material
With the dispersiveness of carbon black, but the effect of embodiment 3 can not be reached.
Compared with comparative example 1, comparative example 3 adds PE waxes, and its melt flow rate (MFR) increased 2g/10min, characterization
Value L reduces 1, and surface quality grades improve 1 grade, illustrates only to add PE waxes slightly improve the mobility of material, but carries
High is limited, while the dispersiveness of carbon black can be improved, but can not reach the effect of embodiment 3.
Compared with comparative example 1, in comparative example 4, coupling agent is added, its melt flow rate (MFR), color table value indicative and surface
Credit rating does not change, and illustrates only to add coupling agent to have no impact to the dispersiveness of the mobility and carbon black of material.
Compared with comparative example 1, mineral oil and PE waxes in comparative example 5, are added, its melt flow rate (MFR) is 27g/10min,
It is in the same manner as in Example 3, understand with reference to comparative example 2 and comparative example 3, mineral oil and PE waxes produce synergy, greatly improved
The mobility of material.Compare with comparative example 2 with comparative example 3, its color table value indicative L is 3, and surface quality grades are improved to 2 grades, are said
It is bright to there is therebetween synergy, it is possible to increase the dispersiveness of carbon black, but the effect of embodiment 3 can not be reached.
Compared with comparative example 1, mineral oil and coupling agent in comparative example 6, are added, now the properties of material and contrast
All same in example 2, illustrates there is no therebetween synergy.
Compared with comparative example 1, PE waxes and coupling agent in comparative example 7, are added, compared with comparative example 3, its every numerical value is equal
Do not change, illustrate there is no therebetween synergy.
Compared with comparative example 5, in embodiment 3, coupling agent is added, its color table value indicative L reduces 1, surface quality grades
1 grade is improve, understands that the addition of coupling agent can produce association and mineral oil and PE waxes between with reference to comparative example 6 and comparative example 7
Same-action, improves the dispersiveness of carbon black, and which individually has no synergy, three's collective effect and mineral oil and PE waxes between
Improve the dispersiveness of carbon black, it is indispensable.
In sum, synergy can be produced between mineral oil and PE waxes, greatly improves the mobility of material so as to melt
Flow rate has reached 27g/10min；In addition synergy is produced between mineral oil, PE waxes and coupling agent three, greatly improve
The dispersiveness of carbon black so as to which color table value indicative L falls below 2, and surface quality grades have reached 1 grade；And then prepare Dispersion on surface
Well, color is goth black, and glossiness has well the goth black PC/ABS alloy materials of uvioresistant photosensitiveness concurrently.
