Method for preparing and printing aluminosilicate polymer composite material for 3D (three-dimensional) printing

Abstract

The invention provides a method for preparing and printing an aluminosilicate polymer composite material for 3D (three-dimensional) printing. The preparation method comprises the following steps: uniformly mixing silicate powder and aluminosilicate powder by using a ball-milling process, and performing screening so as to obtain dried aluminosilicate polymer powder with the particle size of 10-50 microns; adding water into the dried aluminosilicate polymer powder, adding chopped fibers, a high-efficiency water reducing agent and a retarder, and uniformly stirring the mixture so as to obtain aluminosilicate polymer composite material slurry; uniformly adding ceramic particles into the aluminosilicate polymer composite material slurry, thereby obtaining high-viscosity slurry for 3D printing. The printing method comprises the following steps: injecting the high-viscosity slurry for 3D printing into a 3D printer, controlling the temperature of a molding disc to be 25-50 DEG C, and printing a green body of the aluminosilicate polymer composite material through a 3D printer program; and curing the green body, thereby obtaining the finished aluminosilicate polymer composite material for 3D printing forming, wherein the curing temperature is 25-120 DEG C, the curing humidity is 20-90% and the curing time is 3 days.

Description

technical field [0001] The invention relates to a preparation and printing method of a 3D printing material, in particular to a preparation method and a printing method of an aluminosilicate polymer composite material for 3D printing. Background technique [0002] Compared with cement, aluminosilicate polymers have the advantages of low energy consumption, low density, high strength, and excellent impermeability, and have important application prospects in construction, transportation, and national defense. The commonly used molding process of aluminosilicate polymers is casting molding, which is only suitable for simple-shaped components. When preparing complex-shaped components, it is necessary to prepare corresponding complex-shaped molds, which undoubtedly increases the application cost of materials. Contents of the invention [0003] The purpose of the present invention is to solve the problems in the above-mentioned prior art, that is, the molding process of commonly...
