Abstract

The invention discloses a flame-retardant ABS composite material. The flame-retardant ABS composite material is prepared from, by weight, 60-80 parts of ABS resin, 8-15 parts of modified lignin, 5-15 parts of organic silicon flame retardant, 5-12 parts of corn straw power, 5-12 parts of chestnut shell powder, 2-5 parts of ginkgo leaves, 5-10 parts of ABS-g-MAH and 0.5-1 part of antioxidant. A preparation method of the flame-retardant ABS composite material includes the following steps that the ginkgo leaves are cleaned thoroughly, air-dried and smashed into powder of 10-20 mesh; 2, the smashed ginkgo leaves are mixed with the corn straw power and the chestnut shell powder, and the mixture is put for 1-2 days; 3, mixing is performed; 4, melt extrusion, cooling and granulation are performed to obtain the flame-retardant ABS composite material. Waste resources are recycled, and the prepared product is good in flame-retardant effect and good in mechanical performance.

Description

technical field [0001] The invention belongs to the technical field of flame-retardant composite materials, and in particular relates to a flame-retardant ABS composite material and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer (ABS) resin is a general-purpose thermoplastic engineering plastic with superior performance. It has high impact strength, excellent electrical insulation, good processability and chemical stability, and is easy to use. Molded, the product is full of luster and high toughness, and is widely used in household appliances, building materials, automobile industry and other fields. Because many occasions require it to have a certain flame retardant performance, such as fireproof casings, switches, etc., the flame retardant performance of the material is required to reach UL-94V-0 level, so as to improve its safety in use. However, the flame retardancy of ABS resin itself is very low. The most common ...
