The invention discloses a preparing method for
glass fiber enhanced AS composite materials. The preparing method comprises the following steps that A, AS resin, an additive and a
processing agent arethrown into a high-speed mixing
machine according to the formula, and pre-
mixed materials are prepared; the
draw ratio of screws of a double-screw extruder is 48:1, the groove depth ratio is 1.51 or 1.55, 12 areas are divided, the pre-
mixed materials are mainly fed in a first-area discharging
barrel, long
glass fiber is fed in the fifth area, the sixth area and the seventh area, and the rotation speed of a main
machine is 550-850 r / min; and C,
extrusion and pelleting are conducted, and the
glass fiber enhanced AS composite materials are obtained. The screw first-area temperature is 20-50 DEG C, the second-area temperature is 110-130 DEG C, the temperature from the third area to the eleventh area is 210-240 DEG C, and the temperature of a
machine head is 220-240 DEG C. The preparing methodfor the glass
fiber enhanced AS composite materials overcomes the defects that during AS glass
fiber modified
composite material high glass
fiber filling, qualified products are hard to prepare and the strip
breakage rate is high in the production process, wherein the defects exist all the time; and the glass fiber enhanced AS composite materials with high mechanical performance can be prepared, and production stability is good.
