Light-weight fiber reinforced cement board and manufacturing method thereof

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...

Problems solved by technology

[0003]The above-mentioned forms of exterior walls and finishes, for the construction market in China with an annual building area of ​​hundreds of millions of square meters, seem to have few base forms and monotonous finishes. Today's pursuit of personalized architecture is undoubtedly a pity

At the same time, the above-mentioned external wall forms still have problems such as wet operation, high labor intensity, and thermal insulation capabilities that cannot meet the requirements.

In modern architectural research, the goal of separating the functions of wall materials has been pursued, and materials with high thermal resistance are used for insulation, but the external wall panels placed outside the insulation materials have become a bottleneck problem in achieving the goal.
