preparation example Construction
[0037] The preparation method of fiber reinforced ABS material of the present invention comprises the following steps:
[0038] 1) Weigh the materials according to the ratio;
[0039] 2) Pour the materials except fibers into the mixing tank and stir for 5-10 minutes at a stirring speed of 300-450 rpm to mix the materials;
[0040] 3) Treat the glass fiber with a coupling agent and dry it:
[0041] 4) Put the mixed raw materials into the twin-screw extruder for melt extrusion and granulation. By increasing the side feed port, the fibers are added through the side feed port. The processing technology is as follows: the first zone of the twin-screw extruder 200- 210℃, 215-220℃ in the second zone, 215-220℃ in the third zone, 215-220℃ in the fourth zone, 220-230℃ in the fifth zone, 225-230℃ in the sixth zone, 220-225℃ in the seventh zone, 215-220 in the eighth zone ℃; screw speed 300-450 rpm.
Embodiment 1
[0043] Stir the weight ratio of ABS63.0%, toluene xylyl phosphate 10.0%, MPP3.0%, toughening agent HR1816.0%, lubricant 0.5%, antioxidant 1.0%, anti-ultraviolet agent 0.5% in the mixing tank After 5 minutes, the twin-screw extruder is melted and extruded to make granules, and the pre-treated glass fiber is added from the feeding port. Its processing technology is as follows: Twin-screw extruder one zone 200-210°C, two zone 215-220°C, three zone 215-220°C, fourth zone 215-220°C, five zone 220-230°C, six zone 225-230°C ℃, seven zone 220-225 ℃, eight zone 215-220 ℃; screw speed 300-450 rpm. Combining RHCM injection molding process to realize 50-inch ultra-thin, ultra-light, narrow-edge LCD TV frame, the production of products achieves reflective effect, no deformation and warping, surface hardness reaches H, and flame retardancy reaches UL94V0.

Embodiment 2
[0046] Stir the weight ratio of ABS63.0%, toluene xylyl phosphate 10.0%, MPP3.0%, toughening agent HR1816.0%, lubricant 0.5%, antioxidant 1.0%, anti-ultraviolet agent 0.5% in the mixing tank After 5 minutes, the twin-screw extruder is melted and extruded to make granules, and the pre-treated glass fiber is added from the feeding port. The processing technology is as follows: Zone 1 200-210℃, zone 2 215-220℃, zone 3 215-220℃, zone 4 215-220℃, zone 5 220-230℃, zone 6 225-230℃, zone 7 220 -225°C, eight zones 215-220°C; screw speed 300-450 rpm. Combining RHCM injection molding process to realize 50-inch ultra-thin, ultra-light, narrow-edge LCD TV frame, the production of products achieves reflective effect, without any deformation and warping, and the surface hardness reaches 2H.
