Problems solved by technology

In addition, the magnesium oxysulfide board has to go through sawing and surface sanding processes during the production process. During use, it needs to be processed by sawing, drilling, grooving, and screwing. These links will generate dust. However, there will still be a small amount of dust in the air, and front-line workers are prone to symptoms such as skin itching, allergies, mucous membrane inflammation, eye keratitis and conjunctivitis, which seriously endanger the personal health of production workers

preparation example Construction

[0117] Correspondingly, the present invention also provides a method for preparing a homogeneous magnesia gelling material, comprising the following steps:

[0118] (1) Mix the raw materials according to the formula and stir to make a slurry.

[0119] Before mixing, the bamboo silk is pretreated by high-temperature cooking, bleaching and carbonization, and then the bamboo bran is removed with a 10-mesh sieve. Choose dry bamboo filaments with low moisture content, the length of which is ≤15mm, and the diameter of the filaments is ≤1.5mm.

[0120] It should be noted that the bamboo shreds should be added in the final stage of mixing and dispersed evenly.

[0121] (2) Apply mold release liquid to the mold, introduce the slurry into the mold, and comb it flat.

[0122] (3) Lay non-woven fabric on the surface of the slurry, and make the slurry compact by rolling.

[0123] (4) Let it stand until the slurry is hardened, and demould.

[0124] (5) Remove the non-woven fabric on the...

Embodiment 1

[0128] By weight, 120 parts of magnesium sulfate solution, 100 parts of magnesium oxide, 1 part of magnesium oxysulfide modifier, 10 parts of fly ash, 5 parts of silica fume, 2.8 parts of perlite, 12.3 parts of wood bran and 4 parts of 10% concentration For AC foaming liquid mixing, add 12 parts of bamboo silk in the final stage of mixing, and make a slurry after dispersing evenly; apply mold release liquid to the formwork, and introduce the slurry into the mold plate In the middle, comb flat; lay non-woven fabric on the surface of the slurry, and make the slurry compact by rolling. Let it stand until the slurry is hardened, demoulding; trimming ， Remove the non-woven fabric on the surface through surface sanding, check, repair, and maintain to obtain a magnesium oxysulfide flat plate with a thickness of 12mm.

Embodiment 2

[0130] By weight, 122 parts of magnesium sulfate solution, 100 parts of magnesium oxide, 1 part of magnesium oxysulfide modifier, 9 parts of fly ash, 6 parts of silica fume, 2.9 parts of perlite, 11.7 parts of wood bran, 3 parts of all-purpose flour and Mix 5 parts of 10% concentration AC foaming liquid, add 8 parts of bamboo silk in the final stage of mixing, and disperse evenly to make slurry; apply mold release liquid to the formwork, and introduce the slurry into the formwork, Comb flat; lay non-woven fabric on the surface of the slurry, and roll to make the slurry compact. Let it stand until the hardening of the slurry is completed, and demould; after stripping and curing, a magnesium oxysulfide door core board with a thickness of 9mm is obtained.

Abstract

The invention discloses a homogenous magnesian gelling material. The homogenous magnesian gelling material is prepared from, by weight, 220-225 parts of a base material, 0.8-1.2 parts of a modifier, 8-12 parts of fly ash or calcined kaolin, 2-7 parts of silica fume, 2.6-2.9 parts of perlite, 11.5-12.9 parts of sawdust, 6-15 parts of a reinforcing material, 0-6 parts of plain flour and 3-5 parts of an AC foaming liquid mixture with the concentration of 10%. The prepared magnesian gelling material is not a composite layered structure, and is a homogenous material containing the reinforcing material. The invention also discloses a preparation method and product of the homogenous magnesian gelling material. The homogenous magnesian gelling material has the advantages of uniform mechanical performances and strong workability, and the preparation method has the advantages of production cost reduction, production flow simplification and reduction of harms to human bodies.

Description

technical field [0001] The invention relates to a building material, in particular to a homogeneous magnesia gelling material, and accordingly, the invention also relates to a preparation method and a product of the homogeneous magnesia gelling material. Background technique [0002] In contemporary architecture, cement has become an indispensable basic material in the construction industry. Commonly used cements can be divided into Portland cement, aluminate cement and sulphoaluminate cement according to their chemical composition. Their common feature is that they can undergo hydration reactions with water to form hydraulic gelling products. The magnesia cementitious material is another type of cement, mainly including magnesium oxychloride cement, magnesium sulfate cement and magnesium oxysulfide cement, etc., and its characteristic is that some kind of salt solution (also called blending agent) must be added to light-burned magnesia. to form a gelled material. Magnesia...
