Example

[0047]Example 1 to 18

[0048]The content of each component in the ABS resin compositions in Examples 1 to 18 is shown in Table 1.

[0049]The preparation method is: According to Table 1, the other components of the glass fiber will be mixed and uniform, and the main feed port of the twin-screw extruder is added, and the glass fibers are added to the side feed port of the twin screw extruder, and is melted. Mixing, extruding granulation to obtain ABS resin compositions.

[0050]Among them, the screw extruder screw is 36 ~ 48: 1, the twin-screw extruder is 200 ~ 350 rpm, from the screw temperature from the feed opening to the head, 220 to 250 ° C, second area 220 ~ 240 ° C, three districts 210 ~ 220 ° C, four regions 210 ~ 230 ° C, five regions 210 ~ 230 ° C; the mouth temperature is 220 to 230 ° C, the host rotation speed is 100 ~ 500 r / min, the vacuum ≤ 0.1 MPa.

Abstract

The invention discloses a high-toughness low-floating-fiber ABS resin composition. The ABS resin composition is characterized by comprising the following components: an acrylonitrile-butadiene-styrene copolymer, poly(butylene adipate-co-terephthalate), glass fibers, a compatilizer, a coupling agent, a lubricant and a processing aid, wherein the intrinsic viscosity of poly(butylene adipate-co-terephthalate) resin is 2.0 to 2.8 dl/g. According to the invention, a specific type of PBAT is added into an ABS resin matrix and cooperates with the compatilizer, the lubricant and the coupling agent, so the ABS resin composition with high toughness and low floating fiber content is obtained under the condition that the ABS resin composition contains the glass fibers. Under the condition that 30 wt% of the glass fibers is added, no obvious floating fiber exists on the surface of the ABS resin composition, and notch impact strength can reach 15KJ/m<2>.

Description

technical field [0001] The invention relates to the field of modification of polymer materials, and more specifically, to an ABS resin composition with high toughness and low floating fibers, a preparation method and application thereof. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer (ABS) is a thermoplastic polymer material with high strength, good toughness and easy processing and molding. It can be widely used in mechanical electronics and automotive interior and exterior trim or structural parts, household appliances, Toys and other daily necessities. In order to obtain better material strength and dimensional stability, it is usually necessary to modify ABS with glass fiber reinforcement, so that it is suitable for products that require higher strength and dimensional stability, such as housings or brackets for home appliances. [0003] But the addition of glass fiber can greatly reduce some performances of ABS: (1) toughness reduces significan...
