preparation example Construction

[0018] A kind of preparation method of lightweight wallboard provided by the embodiment of the present invention, it comprises the following steps:

[0019] S1, pre-processing

[0020] Please refer to figure 1 , the pre-processing process is the operation before the cloth, this process needs to be operated according to the state of the raw material, if you choose the right raw material, you can omit the pre-processing process. Generally speaking, the pretreatment process includes: pulverizing the first ingredient and the second ingredient to 6-10 mesh, performing granulation treatment and aging for 20-28 hours.

[0021] Specifically, in the operation process, the components in the first ingredient and the second ingredient are uniformly mixed and then pulverized; it is also possible to pulverize separately and then mix. The pulverization process can adopt the method of ball milling, and after pulverization, sieve to obtain materials meeting the particle size requirements. S...

Embodiment 1

[0043] This embodiment provides a formula for lightweight wallboard, including the first ingredient and the second ingredient. In parts by weight, the first ingredient includes 12 parts of tailings slag, 3 parts of waste brick powder, 12 parts of pressed mud, and polishing slag. 50 parts, 3 parts of glass powder, 0.3 parts of silicon carbide and 0.7 parts of sodium tripolyphosphate; the second ingredient includes 12 parts of tailings slag, 3 parts of waste brick powder, 8 parts of pressed mud, 60 parts of polishing slag, 2 parts of bentonite, carbonized 0.2 parts of silicon, 0.3 parts of ferric oxide and 0.7 parts of sodium polyphosphate.

[0044] The present embodiment also provides a method for preparing a multi-layer lightweight wallboard, which uses the above formula, and the specific steps include:

[0045] Firstly, crush the first ingredient and the second ingredient to about 6 mesh and carry out iron removal treatment, then carry out spray granulation and stale for 20 h...

Embodiment 2

[0049] This embodiment provides a formula for lightweight wallboard, including the first ingredient and the second ingredient. In parts by weight, the first ingredient includes 16 parts of tailings slag, 7 parts of waste brick powder, 18 parts of pressed mud, and polishing slag. 60 parts, 8 parts of glass powder, 0.4 parts of silicon carbide and 0.8 parts of water glass; the second ingredient includes 16 parts of tailings slag, 7 parts of waste brick powder, 13 parts of pressed mud, 70 parts of polishing slag, 6 parts of bentonite, and 0.3 parts of silicon carbide 0.4 part, 0.4 part of ferric oxide and 0.8 part of water glass.

Abstract

The invention discloses a preparation method of a light-weight wall board and a multilayer light weight wall board, and relates to the technical field of a building material. The preparation method ofthe light-weight wall board uses a multi-time material distribution mode; a first material and a second material are respectively subjected to material distribution and firing, wherein each of the first material and the second material comprises a base material and a foaming agent; the amount of the foaming agent in the first material is 0.1 to 0.2 percent; the amount of the foaming agent in thesecond material is 0.25 to 0.35 percent. Preferably, the material distribution times is 2 to 3 times. The multilayer light-weight wall board is prepared by the preparation method of the light-weight wall plate. The preparation method has the advantage that the sound isolation, heat isolation and mechanical performance of the finally formed multilayer light-weight wall board are improved.

Description

technical field [0001] The invention relates to the technical field of building materials, and in particular to a preparation method of a lightweight wallboard and a multilayer lightweight wallboard. Background technique [0002] Foamed ceramic insulation board is a new type of lightweight insulation material, which has excellent properties such as high porosity, low thermal conductivity, light weight, high strength, thermal shock resistance, high temperature resistance, corrosion resistance and good mechanical strength, and is widely used. Used in building fireproof materials and sound insulation materials. [0003] At present, the production of foamed ceramic boards is mainly through one-time distribution, foaming and firing in tunnel kilns or roller kilns in the form of stockpiling, and subsequent cutting into boards. The advantage is that the surface of the product is porous and the foaming is even. The disadvantage is that the strength is relatively low and the sound i...
