Abstract

The invention discloses a method for preparing organic-inorganic composite materials of an aluminum rock mineral polymer by use of an impregnation method. The method comprises the following steps: preparing an organic solution containing 0.3% of a curing agent; drying and cooling an aluminum rock mineral polymer, immersing the aluminum rock mineral polymer into the organic solution to steep at normal pressure and normal temperature for 4-6 days, and then taking out the aluminum rock mineral polymer; prepolymerizing the aluminum rock mineral polymer at 80-120 DEG C for 2 hours and then quickly cooling to room temperature; and polymerizing the aluminum rock mineral polymer at 50-80 DEG C for 24-48 hours, and keeping at 80-120 DEG C for 2 hours, so that the aluminum rock mineral polymer completely reacts, so as to prepare the aluminum rock mineral polymer-based organic-inorganic composite materials. The mineral polymer material prepared from aluminous rocks is relatively low in cost, and low in energy consumption; the compressive strength of the organic-inorganic composite materials obtained by steeping the aluminum rock mineral polymer with an organic solution exceeds the strength (greater than C30 and the like) of common concrete; and the organic-inorganic composite materials can be used for preparing functional materials such as ceramic materials, high-strength building boards, and high-strength toughening materials.

Description

technical field [0001] The invention relates to a method for preparing an aluminous rock mineral polymer organic-inorganic composite material by an impregnation method. Background technique [0002] Aluminous rocks contain Al 2 O 3 lower, generally Al 2 O 3 The content is distributed in 40%~50%. In the mining of solid waste for bauxite mines, generally only a small amount is used as a raw material for refractory materials. At present, most of them are abandoned and piled up randomly with the mining, resulting in a huge waste of resources and pollution of the environment. Therefore, it is necessary to focus on solving the problem of comprehensive utilization of aluminous rock resources. [0003] The aluminous rock mineral polymer material is made of aluminous rock, kaolin, and quartz sand in a ratio of 1:0.45:0.43, and adding water glass, an alkali activator, calcium hydroxide and water to make a mineral polymer material. Although this aluminum rock polymer material ha...
