Abstract

The manufacture method for a light wallboard comprises: selecting the material by weight ratio as 30~40 coal ash, 15~25MgO, 10~20 MgCl2, 3~10 lime or cement, 5~15 gypsum / plant powder, and 1~5 glass fiber, as well as the additive contained 0.5~1.5 FeSO4 / oxalic acid, 0.1~1 Na3PO4, 0.1~1 sodium hexametaphosphate, and 1~2 polyvinyl acetate; stirring the MgCl2 in water evenly to prepare the solution with Baume degree as 18~25; adding former additive to stir evenly, putting the material into the solution to prepare the slurry; pouring the slurry into a mould to the half height, then annular spreading the glass fiber and pouring slurry; finally, tamping to form, demolding, and drying. This product has high strength with hard deformation and other merits.

Description

technical field [0001] The invention relates to a lightweight wallboard. Background technique [0002] Lightweight wallboards are widely used in building construction, but the existing lightweight wallboards have the disadvantages of low strength, easy warping, poor water resistance, easy anti-halogenation, or high cost. Contents of the invention [0003] The object of the present invention is to provide a lightweight wallboard with high strength, no deformation, no warping, good water resistance, no anti-halogen and low cost. [0004] The technical solution of the present invention is: the raw materials used in the present invention are composed of ingredients and admixtures. According to the weight ratio, the ingredients are: 30-40 parts of fly ash, 15-25 parts of magnesium oxide, 10-20 parts of magnesium chloride, lime or 3-10 parts of cement, 5-15 parts of gypsum, 5-15 parts of plant powder, 1-5 parts of glass fiber; additives: 0.5-1.5 parts of ferrous sulfate, 0.5-1....
