A kind of preparation method of imitation volcanic rock porous material

Abstract

The invention discloses a preparation method of a volcanic-imitated porous material. The preparation method comprises the following steps: (1) weighing raw materials; (2) putting an active mixed material with alkali activation activity, a non-active mixed material as a filler, a setting time regulator, anti-cracking fiber and inorganic mineral substance pigments into a stirring container, and uniformly stirring, so as to obtain a mixture; (3) respectively dissolving an alkali activator, a chemical foaming catalyst and a tackifying foam stabilizer into water, uniformly stirring, adding an alkali activator water solution, a tackifying foam stabilizer water solution and a chemical foaming catalyst water solution into the mixture, stirring, and adjusting the temperature; and (4) adding a chemical foaming agent into the slurry obtained in the step (3), stirring, pouring the slurry into a mold, uniformly spreading, and after the slurry is coagulated and hardened, carrying out peeling, cutting and maintenance, so as to obtain the volcanic-imitated porous material. The volcanic-imitated porous material is prepared from industrial water slag, and calcination is not needed, so that the energy is saved, and the environment is protected; the coagulating time and the hardening time are short, so that the rapid revolution of the mold is benefited; and the product is high in strength, good in durability and low in cost.

Description

technical field [0001] The invention relates to the fields of architectural decoration and architectural landscape materials. More specifically, it relates to a method for preparing a porous material imitating volcanic rock based on an alkali-activated gelling material. Background technique [0002] Volcanic rocks, also known as extrusive rocks, belong to the category of igneous rocks (igneous rocks). After the liquid magma containing gas slag and solid magma slag is erupted, the temperature and pressure drop rapidly, chemical and physical changes occur, and then a stone with an irregular natural honeycomb porous structure is formed. [0003] This kind of stone is widely used in machine-cut surface sheets, stone pieces, Stone railings, stone carvings, stone furniture, etc. [0004] In recent years, due to the scarcity and limited development of special stone resources such as volcanic rock, some enterprises and scientific research institutions have tried to artificially p...

AI Technical Summary

Problems solved by technology

The former solidifies and hardens slowly, resulting in a longer production cycle; the latter has poor volume stability, resulting in easy cracking of the product and poor durability

And both of them use calcined material-cement as raw material, which consumes a lot of energy and pollutes the environment

In addition, the original strength of these two cement gelling systems is limited, which will inevitably cause the strength of the imitation volcanic rock material to be lower than that of the natural volcanic rock material.
