Abstract

The invention provides a graphite composite ABS multifunctional resin and a preparation method thereof. The graphite composite ABS multifunctional resin comprises the following components in parts by weight: 100 parts of ABS resin, 0.1-5 parts of modified graphite, and 0-5 parts of a compatilizer. The preparation method comprises the following steps: (S1) preparing modified graphite powder; (S2) mixing the graphite powder, ABS resin and the compatilizer to obtain a mixed material; and (S3) compounding the mixed material, water-cooling granulating to obtain composite granules; and processing the composite granules to obtain graphite composite ABS resin. The prepared multifunctional ABS resin has resistance to static electricity, ultraviolet absorption and bacteria, and does not contain pollution type fire retardant. Through continuous molting compounding technique, the invention overcomes the shortcomings of traditional ABS composite multifunctional materials, such as severe mechanical property loss and single function.
