The screw slenderness ratio of double screw extruder is 30~48, and includes at least a side feed feed opening, side feed feed opening
Position in 7th area.
Composite material obtained above is subjected to following performance test, as shown in the table:
Product measure of merit standard: glossiness (%) testing standard is ISO 2883；
Pencil hardness is tested by ASTM D3363 standard, and 750 grams of load；The template of evaluation result presses GB/T17037
Standard injected sample evaluates the metal effect of template.
Metal effect takes artificial visual assessment method, and metal effect presses fine or not degree from 0-10 points, and metal effect is better
Score is higher, selects at least 5 people evaluation, makes even respectively；
Melting means is tested by 1133 standard of ISO, and Izod notched impact strength is tested by ISO 179-1 standard.
Table 2
| Component | Embodiment 1 | Embodiment 2 | Embodiment 3 | Comparative example 1 | Comparative example 2 | Comparative example 3 |
| Glossiness (60 °) | 13 | 20 | 22 | 75 | 42 | 15 |
| Pencil hardness | 2H | H | H | H | 2B | H |
| Metal effect | 10 | 8 | 7 | 10 | 10 | 0 |

| Impact strength (KJ/m2) | 17 | 15 | 14 | 18 | 17 | 20 |
From the comparison of embodiment 1,2,3 and comparative example 1 as can be seen that the ratio of the polystyrene resin of crosslinking SAN reduces
Afterwards, the glossiness of resin is obviously improved, illustrate the polystyrene resin for being crosslinked SAN to resin in illumination, can be effective
The specular reflective of surface light is reduced, rough surface is formed and achievees the effect that dumb light.
From the comparison of embodiment 1,2,3 and comparative example 2 as can be seen that after the ratio reduction of glass microballoon, the pencil of resin
Hardness is obviously improved and mobile performance is also declined, since the density of hollow glass micropearl is approximately that traditional filler material particle is close
Ten parts of degree can mitigate the base weight of product, substitution and the more production resins of saving significantly, reduce product after filling
Cost；Simultaneously its shape be microspheres, in liquid resin than sheet, needle-shaped or irregular shape filler have more compared with
Good mobility, so mold filling is had excellent performance；More importantly this small microballon is isotropic, therefore will not be generated because taking
To the disadvantage for causing different parts shrinking percentage inconsistent, the dimensionally stable of product ensure that, thus keep the mobility of resin more preferable,
And it effectively reduces cost.
In addition, the hollow glass micropearl used is cooperated with other raw materials in the present invention, it also can be to a certain extent
The specular reflective of surface light is reduced, rough surface is formed and achievees the effect that dumb light.
It can be seen that from the comparison of embodiment 1,2,3 and comparative example 3 from being carried out in advance using silane coupling agent to effect pigment
Reason reduces screw rod shearing to the micro-damage of effect pigment will be surface-treated in such a way that side feed is segmented addition,
The effect of improvement effect pigment.
Find out from embodiment 1,2,3 and mixed according to different materials ratio, by material glossiness, pencil hardness, metal effect
After being comprehensively compared with scratch-resistant and comparative example, the effect for exempting to spray scratch-resistant dumb light ABS resin can be realized.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
