Reinforced cement board containing glass fiber in three-dimensional net-shaped structure

Abstract

The invention relates to a reinforced cement board containing glass fiber in a three-dimensional net-shaped structure. The reinforced cement board comprises a solidified layer and a glass fiber framework, wherein the solidified layer is formed by uniformly mixing cement paste with glass fiber chopped wires; the glass fiber framework is in the three-dimensional net-shaped structure; the glass fiber framework consists of upper and lower plain glass fiber nets, and a plurality of warp-direction and weft-direction vertical glass fiber bundles, wherein the solidified layer obtained by uniformly mixing the cement paste with the with glass fiber chopped wires is filled inside and outside the glass fiber framework. The reinforced cement board has the advantages that the cement board contains the glass fiber in the three-dimensional net-shaped structure, so that structure of the cement board is optimized, and preparation types of the materials are reduced; meanwhile, production equipment is simplified, production cost is lowered, various original technical indexes of the cement board are improved, and remarkable progress and high economic benefits are obtained.

Description

[0001] technical field [0002] The invention relates to a building material, in particular to a reinforced cement board containing glass fibers in a three-dimensional network structure and a manufacturing method thereof. Background technique [0003] Since its inception, glass fiber reinforced cement board has been favored by people because of its high strength, light bulk density, fire resistance, and noncombustibility. The glass fiber in the cement board exists in various forms of grid cloth, sheet felt, long fiber, and chopped strand, which greatly improves various physical performance indexes of the cement board. Its shortcoming is that the production process is slightly complicated because it involves various forms of glass fibers, and the matching raw materials, production equipment, and equipment maintenance will also follow up. This series of problems restricts the cement board. development of. The inventor has made more in-depth research on the original basis...
