High-rigidity glass fiber reinforced PA6/ABS composite material

Abstract

The invention discloses a high-rigidity glass fiber reinforced PA6 / ABS composite material, and belongs to the field of polymer composite materials. The PA6 / ABS composite material comprises the following components in percentage by weight: 10 to 80 percent of PA6 resin, 10 to 40 percent of ABS resin, 5 to 40 percent of glass fiber, 1 to 15 percent of compatilizer and 0.2 to 10 percent of other aids. The PA6 / ABS composite material prepared by the technical scheme has the advantages of high rigidity and high-temperature resistance, excellent impact resistance, excellent processability and the like.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and in particular relates to a high-rigidity glass fiber reinforced PA6 / ABS composite material. Background technique [0002] Nylon 6 has excellent mechanical properties, thermal properties, impact resistance and chemical resistance, so it is widely used in automobile parts, electronic and electrical parts, household goods parts and other fields. However, for some products that require high dimensional stability, it is necessary to add ABS resin and glass fiber to adjust. [0003] As we all know, ABS has good elasticity and is an amorphous polymer, while nylon 6 is a semi-crystalline polymer. To make these two polymers in different crystalline states well compatible, a certain amount of Compatibilizers, such as Thomas S.Grant etc. use acrylamide grafted ABS as compatibilizers in USP.4496690 to greatly improve the impact properties of PA6 / ABS alloys. Thomas S.Grant etc. in USP.4740552 ...

AI Technical Summary

Problems solved by technology

[0004] For the compatibilizer in glass fiber reinforced PA6 / ABS, maleic anhydride grafted ABS is generally used. Although it has a certain effect, the heat resistance temperature is not high and the rigidity is not strong.
