Abstract
The present invention relates to a light silicon-magnesium wallboard. The hollow wallboard with transverse and vertical bamboo rids is obtained by that magnesite cement, halogen slices, fly ash, saw dust, gypsum, oxalic acid or phosphoric acid, ferric chloride or ferrous sulphate and triethanolamine are proportionally compounded, then are stirred with water to form slurry and are molded in a mould. The present invention effectively overcomes the anti-halogen defect of magnesite cement products, and has the characteristics of favorable water-resistant performance, no buckling deformation, light weight, high strength, thermal insulation, sound isolation, fire resistance, moth resistance, etc., and the softening coefficient is larger than or equal to 0.95. The light silicon-magnesium wallboard can be optionally sawn, planned, nailed and drilled like wood in the processes of installaion and splicing.
Description
The present invention relates to a kind of architectural shape, exactly is a kind of lightweight silicon-magnesium wall slabstone.
In modern architecture, light material is favourably welcome, the Highrise buildings of skeleton construction particularly, its interior wall uses the lightweight section bar mostly, such as with gypsum or perlite and cement being the wallboard that obtains of raw material processing etc., plasterboard intensity is low, water repelling property is poor, the perlite and cement plate, and its strength and stiffness are all relatively poor.
The present invention is intended to provide for inner wall of building the innovative panellised wall of a kind of light weight, high-strength, fire prevention and processing characteristics excellence.The present invention forms (weight percent, down with) by following former, auxiliary material:
Magnesia cement 27-35%
Halogen sheet 19-25%
Flyash 13-20%
Wood sawdust 30-36%
Gypsum 1.1-1.5%
Oxalic acid or phosphoric acid 0.025-0.027%
Iron trichloride or ferrous sulfate 0.025-0.027%
Trolamine 0.028-0.031%
Above-mentioned former, auxiliary material is industrial goods.Magnesia cement has another name called magnesia, its magnesium oxide (MgO) content 〉=75%.Halogen sheet main component is magnesium chloride (MgCl2), its content 〉=46%.
Former, auxiliary material weighing by a certain percentage, preparation back are stirred into slurry with water, slurry is dropped into die for molding, the demoulding again, last in the dry hollow wall panel that just obtains certain specification.
The needs that water mold forming are not only in the effect of water among the application, play a spot of auxiliary material of dissolving simultaneously, make it the effect that mixes and promote to undergo phase transition each other with raw material, but the overwhelming majority will be sloughed after moulding.
The present invention has overcome the chronic disease of the anti-halogen of magnesia cement goods effectively, for new approach has been opened up in its application at building materials field.
Wallboard provided by the present invention, not buckling deformation, water repelling property is good, coefficient of softening 〉=0.95, have light weight, high-strength, adiabatic, sound insulation, fire prevention, characteristics (auspicious seeing attached list) such as mothproof, especially have excellent processing characteristics, just when splicing is installed, can saws, can create, can follow closely, can bore as timber by people's wish.
