Abstract

The invention provides an electric conduction compound ABS / PLA material for 3D printing wires. The electric conduction compound ABS / PLA material is prepared from the following raw materials in percentage by weight: 15-30% of a synthetized material ABS by using a bulk method, 15-30% of a synthetized material ABS by an emulsion method, 1-10% of copolymers of styrene -acrylonitrile -2-methylpropenoic acid glycidyl ester, 0.01-0.05% of triphenylphosphonium bromide, 5-15% of metallic nickel powder , 30-50% of polylactic acid , 1-5% of walled carbon nanotubes and 1-5% of graphene microchips. According to the electric conduction compound ABS / PLA material disclosed by the invention, the nickel powder, the graphene microchips and the carbon nano tubes are optimized and collocated, so that the requirements for electrical conductivity by using lower volume resistivity under the low content of an electric conduction additive are met, the ABS material mixed in different particle diameters enables the particle diameters in the compound material to present bimodal distribution, and the toughness is enhanced; the consistency and the cocontinuity of ABS and PLA are good, so that the electric conduction compound ABS / PLA material is particularly suitable for strip-shaped high electric conduction materials required by 3D printing.

Description

technical field [0001] The invention belongs to the technical field of conductive materials for 3D printing wires, and more specifically relates to a conductive ABS / PLA composite material for 3D printing wires and its preparation method and application. Background technique [0002] At present, the ABS strips for 3D printing sold in China include imported STRATASYS P400 ABS, domestic montmorillonite modified ABS (CN104672755A), glass fiber reinforced ABS (CN104559034A), polycarbonate modified ABS (CN104559023A), rubber particle double ABS with peak distribution (CN104072935A, CN103980429A), carbon black conductive modified ABS (CN103788565A), among them, the conductive ABS strip for 3D printing has the carbon black conductive modified ABS disclosed in CN103788565A, but the carbon black conductive content reaches 35 parts by mass Above, the high filler content seriously affects the printing effect of ABS strips (low precision and delamination). And the volume resistivity of ...
