Problems solved by technology

Among them, ABS is currently the largest and most widely used general-purpose engineering plastic. It organically unifies the various properties of acrylonitrile, butadiene, and styrene, and has high toughness, hardness, and rigidity. However, when used in For higher-level products, some mechanical properties cannot meet its requirements, especially the impact strength, so it is necessary to develop ABS consumables for 3D printing with better mechanical properties

Abstract

The invention discloses an acrylonitrile-butadiene-styrene (ABS) composite material for three-dimensional (3D) printing, and a preparation method of the ABS composite material, and relates to the technical field of 3D printing. The ABS composite material is prepared from the following raw materials in parts by weight: 70-80 parts of ABS resin, 7-15 parts of a maleic anhydride grafted toughening agent, 10-20 parts of cardanol, 1-3 parts of a lubricating agent, 1-3 parts of toner and 0.2-1 part of an antioxidant. According to the preparation method, the maleic anhydride grafted toughening agentand the cardanol are cooperatively used for reinforcing and toughening the ABS resin, and the processing fluidity of the ABS also can be improved; the maleic anhydride grafted toughening agent, the cardanol and the ABS resin are extruded and granulated after being subjected to internal mixing, and are then evenly mixed; after that, the mixture is matched with other components such as the lubricating agent, the toner and the antioxidant according to a reasonable ratio; the temperature in the process is reasonably optimized, and extrusion wire-drawing is performed. A prepared 3D printing consumable product is good in performance and has an obvious toughening effect.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to an ABS composite material for 3D printing and a preparation method thereof. Background technique [0002] 3D printing is one of the rapid prototyping (RPM) technologies, born in the late 1980s. It uses polymers and metals as consumables, and uses its adhesive properties to print digital model files into Solid molding technology. This technology can simplify the product manufacturing process, shorten the product development cycle, improve efficiency, and reduce costs. It can be widely used in industries such as national defense, aerospace, automobiles, and metal manufacturing. It is considered to be a major technological achievement in the manufacturing field in recent years. The 3D printing rapid prototyping technology based on the principle of fused deposition rapid prototyping (RPM) is one of the most viable rapid prototyping technologies at present. The consumables used a...
