Nailable fiber cement board and preparation method thereof

Abstract

The invention relates to a nailing fiber cement board and a preparation method thereof. The nailing fiber cement board is prepared from the following components: water, cement, quartz sand, lignocelluloses, expanded perlite and production remainders, wherein the components are proportioned by weight percent as follows: 35 to 65 percent of quartz sand with granularity greater than 180 meshes, 30 to 55 percent of 42.5 or 52.5 cement, 6 to 12 percent of lignocelluloses, 1 to 10 percent of expanded perlite, and 3 to 10 percent of production remainders. The components are made into a novel board by virtue of a series of production processes. The nailing fiber cement board solves the problems that the board is poor in bending performance, easy to fracture when nailed and complex in procedures; on the premise of maintaining high bending resistance, high fire resistance, high water and damp resistance and the like, the nailing fiber cement board also has reliable bending performance and can be directly installed without fracture by directly using pop-gun nails such as straight nails, steel nails, mosquito nails and the like, thereby greatly facilitating the on-site construction, reducing the operation procedures, and improving the construction efficiency.

Description

technical field [0001] The invention relates to the field of construction products, in particular to a nailable fiber cement board and a preparation method thereof. Background technique [0002] Fiber cement boards or calcium silicate boards currently on the market are generally composed of siliceous calcareous materials and wood cellulose fibers. A high-strength and high-hardness tobermullite crystal is formed under 10 bar high pressure, so that the fiber cement board or calcium silicate board has excellent characteristics such as high flexural strength, good fire resistance, and waterproof and moisture resistance. It is mainly used in the fields of exterior walls, interior walls, decorative substrates, and ceilings. However, when installing and using interior walls, ceilings, and lining boards, light steel keels or wooden keels are generally used as the skeleton, and lines are drawn on the panels first. , Pre-drill holes with a drill bit, and then use self-tapping screws ...

AI Technical Summary

Problems solved by technology

[0004] The patent of the invention aims to solve the problems of poor bending performance of the board, easy cracking when nailing, and complicated procedures. It discloses a nailable fiber cement board mainly used for interior walls, which can maintain high flexural strength, fire prevention, waterproof and moisture-proof performance. Under the same condition, it also has reliable plate bending performance. It can be directly installed and used with air gun nails such as straight row nails, steel row nails and mosquito nails without cracking, which greatly facilitates on-site construction, reduces operating procedures, and improves construction efficiency.
