Abstract
The invention relates to a lightweight environmental protection glass magnesium board, and belongs to the technical field of building decoration materials, wherein the lightweight environmental protection glass magnesium board is formed by mixing the following raw materials by weight: 60-70 parts of light calcined magnesia, 40-50 parts of anhydrous magnesium chloride, 3-9 parts of a foaming agent, 40-50 parts of a lightweight filler, and 1-6 parts of a reinforcing material, wherein the forming agent is n-pentane. According to the present invention, the foaming agent is added, such that the slurry volume is reduced, the product specific gravity is reduced in the case of no reduction of the product strength and the fire resistance, the air-drying time is reduced, the production process is shortened, and the cost is reduced.
Description
Technical field
A kind of light-weight environment-friendly glass of the present invention magnesium plate, belongs to technical field of construction and decoration materials.
Background technology
Glass fibre and magnesium cement board (being commonly called as magnesium oxide plate) is with magnesium oxide, magnesium chloride, and water ternary system, be configured and add properties-correcting agent and make, the magnesium gelatinous material of stable performance, with neutral and alkali glass fiber net for strongthener, take light material as the novel uninflammability finishing material that weighting material is composited.
In the selection of light filler, the perlite of commercially available employing generally uses perforate perlite, perforate perlite is also known as normal expanded perlite, after making an addition to the slurry producing glass magnesium plate, easily a large amount of magnesium chloride solution absorbed in slurry, originally the magnesium chloride should participating in hydration reaction with magnesium oxide is absorbed in a large number, be hidden in this perforate perlite, thus cause the poor stability of magnesia oxychloride cement, finished product needs to soak out through the soaked chlorion absorbed magnesium chloride for a long time, cause the production technique time long, and the chlorion soaked out is also very limited, even there is the phenomenon that cannot soak out.So that curing time is long, finished product needs through being soaked in water for a long time, unnecessary chlorion contained inside glass magnesium plate is soaked out, thereby produces the longer airing time, extends the production cycle.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, and technical problem to be solved is to provide a kind of light-weight environment-friendly glass magnesium plate.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of light-weight environment-friendly glass magnesium plate, is mixed by the raw material of following weight: light calcined magnesia 60-70 part, Magnesium Chloride Anhydrous 40-50 part, whipping agent 3-9 part, light filler 40-50 part, strongthener 1-6 part.
Described whipping agent is Skellysolve A.
Described light filler is made up of rice husk and perlite.
Described light calcined magnesia adopts magnesite to make through calcining levigate again at 700 ~ 800 ° of C, and fineness scope is 80 order ~ 120 orders.
Described strongthener is medium-alkali glass fiber cloth or non-woven fabrics.
Compared with prior art the present invention has following beneficial effect.
Present invention adds whipping agent, thus increase slurry volume, when not reducing product strength and fire performance, reducing product proportion, reduce airing air-dry time, shorten production technique, reduce costs.
