Abstract

The invention discloses a preparation process of a modified acrylonitrile-butadiene-styrene (ABS) material for a 3D printer. The preparation process comprises the following steps: 1) weighing various components and preparing polybutadiene rubber; (2) dissolving the polybutadiene rubber in prepared styrene and acrylonitrile monomer; and carrying out phase transformation in a reactor; 3) carrying out phase transformation for multiple stages, and implementing devolatilization when the transformation rate reaches more than 70%; 4) granulating molten materials to obtain small-size ABS particles; and 5) mixing, extruding and granulating small-size ABS particles and large-size PSF particles to obtain a target product. The ABS modified material similar to a core-shell structure is prepared by mixing, extruding and granulating the small-size ABS particles and large-size PSF particles; in the extruding process, the small-size ABS particles are covered by large-size PSF particles which are comparatively large in granularity, so that the shell of the core-shell structure is formed; and the final material, which integrates advantages of the ABS material and the PSF material, has good mechanical property and relatively high bending strength.

Description

[0001] technical field [0002] The invention relates to a preparation process of a polymer material, in particular to a preparation process of a modified ABS material for a 3D printer. Background technique [0003] At present, the production methods of ABS resin mainly include emulsion grafting method, emulsion grafting-blending method, continuous bulk method, bulk-suspension method, emulsion grafting-suspension method, emulsion grafting-continuous bulk method, etc., among which various Production methods have their advantages and disadvantages, among which the most competitive methods are emulsion grafting-bulk SAN blending method and continuous bulk method. Although the process has the advantages of simple process, small investment and less pollution, the prepared ABS material cannot A high gloss is achieved and the mechanical properties of the material, such as flexural strength, are poor. In order to make full use of the advantages of this production method and effect...
