Glass fiber reinforcement cement board and production method thereof

Abstract

The invention relates to a building material and a method for preparing the same, in particular to a glass fiber reinforced cement board and a method for preparing the same. The glass fiber reinforced cement board comprises the following components in weight portion: 100 portions of Portland cement, 13.6 to 15 portions of high alumina cement, 3.1 to 3.4 portions of fly ash, 5.7 to 6.3 percent of plaster stone powder, 120 to 132 portions of ceramsite, 6.5 to 7.1 percent of foaming agent, 74.5 to 81.3 percent of dispersing agent, 53 to 58.7 portions of pure water and 3.6 to 4 portions of plastic-coated glass fiber grid cloth. The preparation method sequentially comprises the following steps: mixing weighed-up solid materials, adding weighed-up liquid materials in the previous step, cavity forming, roll extruding, vibration, cutting and curing. The invention has the advantages that: the glass fiber reinforced cement board has advantages of light volume weight, high strength, low dry shrinkage wet swelling coefficient, no after expansion and shrinkage, corrosion resistance, sound insulation, heat insulation, fire resistance and non-combustion; the preparation method has the characteristics of scientific and reasonable method, continuous production, high efficiency and low cost, flat board surface, convenient in-site mounting and the like; the glass fiber reinforced cement board is good in water resistance, and particularly applied to the finishing of internal and external walls and ceilings of various buildings in wet environments; moreover, the glass fiber reinforced cement board and a method for preparing the same have the advantages of ensuring the strength and service life of cement due to the adoption of the plastic-coated anti-alkali glass fiber grid cloth, along with reasonable blending ratio and reduced alkalinity.

Description

technical field [0001] The invention relates to a building material and a manufacturing method thereof, in particular to a glass fiber reinforced cement board and a manufacturing method thereof. Background technique [0002] In the known technology, with the rapid development of the national economy, the increase of population and the improvement of living standards, the scale of economic construction and infrastructure construction is expanding rapidly, and the building is developing towards multi-level and diversified directions. The demand for materials and quality requirements are also getting higher and higher. Among them, the market for fiber reinforced cement boards in the new residential construction and residential decoration markets is very large. This is mainly because fiber reinforced cement boards are economically cost-effective and durable. The research on the formula is also emerging in an endless stream, and it is developing in the direction of high strength,...
