High-performance anti-deformation 3D printing material and preparation method thereof

Abstract

The invention discloses a high-performance anti-deformation 3D printing material, which comprises the following raw materials in parts by weight: 1 part of acrylic emulsion and 20-200 parts of inorganic compound powder. The preparation method comprises following steps: mixing and stirring acrylic emulsion and inorganic compound powder by a mixing device; introducing uniformly mixed raw materials into a drying device; firstly, making the raw materials fall into a rotary drum through a first material guide pipe; introducing the centrifugally dried raw materials into a conveying device; making centrifugally dried raw materials fall onto a conveying belt conveying the raw materials through the conveying belt, heating the raw materials on the conveying belt during the conveying of the raw materials, introducing residual mother liquor into a condenser from a condenser connecting pipe, making the raw materials conveyed to the top of a conveying box fall into a crushing device; and grinding the raw materials by two sets of grinding rollers driven by a gear and a transmission shaft so as to obtain the 3D printing material. The 3D printing material has high structural strength and deformation resistance of the inorganic compound and high flexibility of an organic polymer, and the preparation process is high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and relates to a 3D printing material and a preparation method thereof, in particular to a high-performance anti-deformation 3D printing material and a preparation method thereof. Background technique [0002] 3D printing technology is based on digital model files, and uses bondable materials such as powdered metal or plastic to manufacture entities by layer-by-layer printing. [0003] In the prior art, 3D printing materials are currently mainly made of gypsum, photosensitive resin, and plastic raw materials, which have defects such as poor printing accuracy, insufficient strength of solid finished products, and slow printing speed, which are difficult to meet modern industrial applications; at the same time, 3D printing In the process of material preparation and production, when stirring and mixing 3D printing raw materials, a set of stirring shafts and stirring blades are usually used to mi...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, 3D printing materials mainly use gypsum, photosensitive resin, and plastic raw materials. They have defects such as poor printing accuracy, insufficient strength of solid finished products, and slow printing speed, which are difficult to meet. Modern industrial application; at the same time, during the preparation and production process of 3D printing materials, when mixing 3D printing raw materials, a set of stirring shafts and stirring blades are usually used to mix the raw materials in the mixing tank, and this stirring method exists The stirring efficiency is relatively low, and it takes a long stirring time to fully mix the raw materials, which greatly reduces the efficiency of 3D printing raw material mixing, and prolongs the cycle of 3D printing raw material preparation; and its subsequent production cycle is relatively long and the process is complicated, making 3D printing Due to the low efficiency of printing raw material preparation, a high-performance anti-deformation 3D printing material and its preparation method are proposed
