Abstract

The invention provides a light-weight fiber reinforced cement board. The light-weight fiber reinforced cement board comprises 100 parts of cement, 20 parts of silicon powder, 15 parts of calcium powder, 5 to 10 parts of expanded perlite, 4 parts of paper pulp, 5 to 15 parts of wood fibers, 5 to 10 parts of wood powder, 1 to 2 parts of polypropylene fibers, 0.8 part of methyl cellulose, 1 to 3 parts of sodium chloride, 1 to 3 parts of sodium sulphate, 2 to 3 parts of sodium silicate, and 230 to 300 parts of water. The invention also discloses a method for manufacturing the light-weight fiber reinforced cement board, which comprises the following steps of: 1, weighing each component according to formula; 2, placing the weighed dry materials into a mixer for uniformly mixing; 3, preparing wet materials, placing the mixed materials obtained by the step 2 into a kneader, adding water and the wet materials into the mixed materials, and kneading the mixture; and 4, placing the kneaded slurryinto a mold, performing compression moulding by using a plate fluidizing machine, and then demolding. The manufacturing method greatly improves the tensile strength, the impact strength, the water-retaining property, and the extrusion property of the materials.

Description

technical field

[0001] The invention relates to a novel building material product and a manufacturing method, in particular to a lightweight fiber-reinforced cement board and a manufacturing method thereof. Background technique

[0002] my country's building exterior wall matrix can be classified into four categories: (1) clay brick exterior wall; (2) build the matrix with various blocks, and then plaster the inside and outside of the wall to form the exterior wall; (3) reinforced concrete as the foundation wall, Then paste the insulation board inside to form the outer wall; (4) some newly developed ones such as Taibai board, Zhule board, etc. The exterior wall decoration forms include: spraying paint after plastering the surface with mortar, and pasting tiles and mosaics after plastering the surface with mortar. High-grade decorations include: glass curtain wall, pasting stone and aluminum-plastic panels, etc.

[0003] The above-mentioned forms of exterior walls and finis...
