Abstract
The invention discloses an enhanced flame-retardant ABS material and a preparation method thereof. The material comprises the following raw materials: 100 parts of ABS, 15-40 parts of glass fiber, 7-15 parts of halogen free fire retardant, 2 parts of lubrication dispersant and 3 parts of anti-oxidant, the preparation method comprises the following steps: the raw materials except for the glass fiber are mixed in a high-speed mixer according to proportion, the raw materials are uniformly mixed and then granulation by extrusion is carried out by a double screw extruder, glass fiber is added from a second feed inlet, wherein the processing temperature is 180-220 DEG C. The prepared material has the advantage of halogen free environmental protection, strong impact-resistance capability, and aging resistance performance, and can be used for automobile interior decorative parts and household electrical appliance housing.
Description
Technical field
The present invention relates to engineering plastics field, be specifically related to the preparation method of a kind of enhancing, anti-flaming ABS material.
