Method for manufacturing calcium silicon light-weight wallboard

Abstract

The invention relates to the technical field of building materials and particularly relates to a method for manufacturing a calcium silicon light-weight wallboard. The method comprises the following steps: A, preparing brine; B, preparing a magnesite foaming agent; and C, manufacturing a light-weight wallboard material: firstly adding 45-50 parts by weight of evenly-mixed brine into an agitator, starting the agitator to homogenize the brine, secondly adding 50-56 parts by weight of magnesium oxide and 10-15 parts by weight of gypsum powder, clockwise-anticlockwise stirring for 10-15 minutes, adding coal ash and palm fibers to obtain a first fixture, throwing the magnesite foaming agent into the first mixture by a foaming machine, stirring to obtain a second mixture, pouring the second mixture into a mold, and performing demolding and curing, thereby obtaining the light-weight wallboard material. The manufactured product has the advantages of no scumming, light weight, good heat preserving performance, high strength and enhanced toughness, and the product strength is scarcely affected.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a wall material and a manufacturing method of the lightweight wall material. Background technique [0002] In the patent No. 200610059751.6, the inventor discloses a method for manufacturing wallboards in the patent titled "Silicon Calcium Plant Fiber Lightweight Wallboard and Its Manufacturing Method". The main raw material used is plant fibers. It is recognized by the society, but such a manufacturing method has the disadvantages of complicated process and high cost. [0003] In the prior art, the main raw material used for interior wallboards is still cement. Due to the short setting time of gypsum, the extrusion molding process is generally used for interior wallboards, which takes a long time, so the application of gypsum in the manufacture of wallboards restricted.

[0002] In the patent No. 200610059751.6, the inventor discloses a method for manufacturing wallboards in the patent titled "Silicon Calcium Plant Fiber Lightweight Wallboard and Its Manufacturing Method". The main raw material used is plant fibers. recognized by the society, but such a manufacturing method has the disadvantages of complicated process and high cost

[0003] In the prior art, the main raw material used for interior wallboards is still cement. Due to the short setting time of gypsum, the extrusion molding process is generally used for interior wallboards, which takes a long time, so the application of gypsum in the manufacture of wallboards restricted

[0004] On the other hand, along with the construction of a conservation-oriented society, the wastes are required to be fully utilized, but in reality, the utilization rate of industrial wastes is still low, and many of them are discarded as wastes, and the wastes as wastes also take up space; in the prior art In the production of high-quality wall materials, the incorporation of waste slag often affects the strength of wall materials due to unreasonable technology

[0005] The inventor disclosed in the patent application number 201210450140.X titled "a calcium-silicon lightweight wall material and its manufacturing method" that the manufacturing method of the calcium-silicon lightweight wallboard is to mix gypsum, cement, fly ash, etc. Calcium-silicon wallboard is made by mixing, but this method still has the disadvantages of high density, poor thermal insulation performance, and affecting the use effect.
