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...

Abstract

The invention discloses a preparation method of a light-weight wallboard and a multilayer light-weight wallboard, and relates to the technical field of building materials. The preparation method of the light-weight wallboard adopts the method of distributing the first batch and the second batch separately, and then fires them; wherein, both the first batch and the second batch include a base material and a foaming agent, The amount of the foaming agent in the first batch is 0.1%-0.2%, and the amount of the foaming agent in the second batch is 0.25-0.35%; preferably, the number of times of distributing is 2-3 times. The multi-layer light wallboard is prepared by applying the above-mentioned preparation method of the light wallboard. The preparation method of the invention improves the sound insulation, heat insulation and mechanical properties of the finally formed multi-layer lightweight wallboard.

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...
