Abstract

The invention relates to a lava slab and a processing method thereof. The lava slab comprises slurry for the lava slab and glass fiber cloth. The slurry comprises the following raw materials in partsby weight: 35-45 parts of cement, 35-45 parts of magnesium oxide powder, 5-10 parts of vermiculite powder, 2-3 parts of perlite particles, 1-2 parts of heterochain high molecular polymers, 2-3 parts of cement modifiers and 30-40 parts of water. The produced lava slab has porous holes, and can realize a good sound absorption and noise reduction effect, which fills in the gap of the prior art that the cement board does not have the effect of sound absorption and noise reduction, and improves the competitiveness of the lava slab to enter the middle- and high-end market. In addition, the slurry includes 5-10 parts of vermiculite powder, and the scheme has the following effects: the lava slab has porous holes, and vermiculite has a higher layer charge number, so that the vermiculite has a higher cation exchange capacity and a stronger cation exchange adsorption capacity; therefore, the porous lava slab with the addition of vermiculite powder has an increased release area of negative oxygenions.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a slurry for lava slabs, a lava slab and a processing method thereof. Background technique [0002] Cement board is a building slab produced by processing cement as the main raw material. It is a building product that can be cut, drilled and carved freely between gypsum board and stone. It is better than gypsum board and wood board in terms of fire resistance, Waterproof, anti-corrosion, insect-proof, sound-proof and far lower than the price of stone, it has become a widely used building material in the construction industry. [0003] The cement board is currently only in the basic stage of the board, and does not have the function of sound absorption and noise reduction, which prevents it from entering the ranks of high-end decorative products. [0004] Therefore, how to provide a lava slab capable of absorbing and reducing noise is an urgent problem to be solved by ...
