Geopolymer slurry, product containing geopolymer slurry as well as preparation method and application of geopolymer slurry
The invention relates to geopolymer slurry capable of 3D printing, a product containing the geopolymer slurry and a preparation method and application of the geopolymer slurry. The geopolymer slurry comprises an aluminosilicate precursor; the alkali activator comprises MOH, M2O.nSiO2 and H2O, and M is an alkali metal; and a modifier. The preparation method of the geopolymer slurry comprises the following steps: weighing an aluminosilicate precursor; the preparation method comprises the following steps: respectively weighing MOH, M2O.nSiO2 and H2O according to preset MOH/M2O.nSiO2 and H2O/M2O.nSiO2, and mixing and stirring the MOH, the M2O.nSiO2 and the H2O to prepare an alkali activator, weighing a predetermined content of modifier, and mixing the alkali activator and the modifier to prepare an alkaline mixed solution; an aluminosilicate precursor and an alkaline mixed solution are mixed to form a geopolymer slurry. The optimized geopolymer slurry composition is determined by taking the aluminosilicate precursor as a solid raw material and polyethylene glycol (PEG) as a modifier under the action of alkaline assistants such as alkali metal hydroxide and water glass, and a prepared geopolymer sample is excellent in mechanical property and is expected to be used in the field of geopolymer printing.
本发明涉及一种可3D打印的地聚物浆料、包含其的制品及其制备方法和应用，其中该地聚物浆料包含铝硅酸盐前驱体；碱激发剂，包含MOH、M2O·nSiO2和H2O，其中，M为碱金属；和改性剂。该地聚物浆料的制备方法包括称取铝硅酸盐前驱体；按照预设MOH/M2O·nSiO2，H2O/M2O·nSiO2分别称取MOH、M2O·nSiO2和H2O，并将其混合搅拌以配置碱激发剂，其中，M为碱金属；称取预定含量的改性剂，并将碱激发剂和该改性剂混合以配置碱性混合溶液；将铝硅酸盐前驱体和碱性混合溶液混合以形成地聚物浆料。本发明以铝硅酸盐前驱体为固体原料，在碱金属氢氧化物和水玻璃等碱性助剂作用下，以聚乙二醇(PEG)为改性剂，确定了优化的地聚物浆料组成，制备出的地聚物样品力学性能优异，有望用在打印地聚物领域。
