preparation example Construction

[0025] Some embodiments of the present invention also provide the preparation method of the above-mentioned foamed ceramics, which includes: firing according to the ratio of raw materials to obtain foamed ceramics. The foamed ceramics fired through the above raw material ratios have good mechanical strength and fire resistance, and the preparation method is simple to operate, energy-saving and environment-friendly.

[0026] In order to ensure the firing effect of the foamed ceramics, in some embodiments, the raw material mixture needs to be granulated first, and then the granulated raw material particles are placed in a mold for firing. By means of granulation, the agglomeration of raw materials can be avoided, which will affect the performance of the final fired foamed ceramics.

[0027] Furthermore, in order to make the foamed ceramics formed in the mold have a good structure, there are certain requirements on the particle size of the granulation. Generally, the particle siz...

[0046] (2) Weigh the main ingredient formulation and the modified soil according to the mass ratio of the main ingredient formulation of the foamed ceramics to the modified soil being 90:10.

[0047] (3) Weigh the composite foaming agent according to 0.65% of the total weight of the foamed ceramic formulation and the modified soil, wherein the mass ratio of silicon carbide and manganese oxide is 8:5.

[0048] (4) Pour the weighed foam ceramic main ingredient formula, modified soil and composite foaming agent powder into a ball mill jar, and bal...

Embodiment 2

[0054] This embodiment provides a preparation method for prolonging the refractory limit time of foamed ceramics, comprising the following steps:

[0055] (1) Weighing the foamed ceramic main ingredient formula, said main ingredient formula comprises 67 parts of polishing slag, 14 parts of Fuzhou potassium sodium sand, 6 parts of Jinyi Tao foamed ceramic fine powder, 6 parts of bentonite, 2 parts of talcum grains and 5 Granite Stone Dust.

[0056] (2) Weigh the main ingredient formulation and the modified soil according to the mass ratio of the main ingredient formulation of the foamed ceramics to the modified soil being 85:15.

[0057] (3) Weigh the composite foaming agent according to 0.75% of the total weight of the main ingredient of the foamed ceramics and the modified soil, wherein the mass ratio of silicon carbide and manganese oxide is 8:5.

[0058] (4) Pour the weighed foam ceramic main ingredient formula, modified soil and composite foaming agent powder into a ball ...

Abstract

The invention discloses foamed ceramic as well as a preparation method and application thereof. The foamed ceramic is prepared from the following raw materials in parts by weight: 60-70 parts of polishing slag, 8-18 parts of medium-temperature sand, 5-10 parts of foamed ceramic fine powder, 2-8 parts of bentonite, 1-5 parts of talc particles, 5-15 parts of granite stone powder, 5-25 parts of modified soil and 0.4-1 part of a foaming agent. The modified soil is prepared from the following chemical components in percentage by weight: 52 percent to 56 percent of SiO2, 35 percent to 40 percent ofAl2O3, 1 percent to 3 percent of CaO, 1.5 percent to 2 percent of Fe2O3, 0.1 percent to 0.3 percent of TiO2, 0.1 percent to 0.3 percent of MgO, 1.5 percent to 2.5 percent of K2O, 0.8 percent to 1.5 percent of Na2O and 0.01 percent to 0.05 percent of L.O.I. Specific ceramic raw materials are selected and scientifically proportioned, and modified soil is added, so that the matrix strength of the foamed ceramic is improved, and the fire endurance of the foamed ceramic is improved.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a foamed ceramic and its preparation method and application. Background technique [0002] Foamed ceramics is a high-porosity closed-cell ceramic body made of industrial solid waste and some tailings, combined with advanced sintering technology and foaming technology. It is a new type of environmentally friendly building material that conforms to the concept of energy saving and emission reduction, and has broad prospects for the application of external wall insulation panels and interior wall insulation panels. However, the fire resistance limit time of the foamed ceramics currently produced in the industry is about 0.75h, which can only be used as a partition wall of a house, and cannot be applied to floors, evacuation stairs, firewalls or load-bearing walls. Therefore, how to prolong the refractory limit time of foamed ceramics while meeting the requirements of...
