Abstract

The invention discloses a fiber glass reinforcement PBT / ABS composite material with good surface and high flow and a preparation method thereof. The composite material comprises the following components by weight percentage: 10 to 65 percent of PBT resin, 10 to 65 percent of ABS resin, 1 to 10 percent of compatilizer, 10 to 40 percent of fiber glass, 1 to 5 percent of lubricant, and 0.5 to 4 percent of other assistants. The method comprises the following steps: weighing each material except the fiber glass, mixing the materials in a mixer for 3 to 5 minutes, adding the evenly mixed materials into a double-screw extruder, adding the fiber glass into the mixture from a first exhaust port, wherein the temperatures from a feed port to an extruding die head are between 160 and 180 DEG C, between 190 and 220 DEG C, between 210 and 240 DEG C, between 220 and 250 DEG C and between 210 and 240 DEG C respectively, and the rotating speed of a host is 20 to 50 hertz, and then using a plastic injection molding machine to prepare samples. The composite material has the advantages of good surface gloss, good performance and easy processing.

Description

technical field [0001] The invention relates to a PBT / ABS composite material, in particular to a good surface and high flow glass fiber reinforced PBT / ABS composite material and a preparation method thereof, belonging to the field of polymer composite materials. Background technique [0002] PBT resin is a crystalline polymer with excellent mechanical properties, electrical properties, and other physical and chemical properties, especially good fluidity and easy processing, and is widely used in the automotive, electronic and electrical industries. However, for some products with high dimensional stability and strict surface requirements, ABS resin and glass fiber need to be added to adjust. [0003] As we all know, ABS has good elasticity and is a non-crystalline polymer. To make these two polymers in different crystalline states compatible, a certain amount of compatibilizer is generally added, such as Katsumata et al. in USP .5891943 on the polyolefin graft polymer (PMMA...
