Technical Field

The invention relates to the field of sound insulation materials, in particular to a reverse sound insulation type cement board.

Background

The cement board is a building flat plate which is produced by processing cement as a main raw material, is a building product which is arranged between a gypsum board and a stone and can be freely cut, drilled and carved, and becomes a building material widely used in the building industry due to the superior fireproof, waterproof, anticorrosion, insect prevention and sound insulation performance of the cement board and the wood board and the price far lower than that of the stone. The cement board is prefabricated and cast-in-place.

Cement boards are various in types and are mainly classified into common cement boards, fiber cement boards and fiber cement pressure boards according to grades; the board is mainly divided into a non-pressing board (a common board), a fiber reinforced cement board and a high-density fiber cement pressing board according to the strength; the fiber is mainly divided into a chrysotile fiber cement board and a non-asbestos fiber cement board according to the used fiber.

Fiber cement board: the main difference between the fiber reinforced cement board and the common cement board is that various fibers are added as reinforcing materials, so that the strength, flexibility, folding resistance, impact resistance and the like of the cement board are greatly improved. The added fiber is mainly mineral fiber such as asbestos, vegetable fiber such as pulp, synthetic fiber such as vinylon, artificial fiber such as glass fiber, etc. According to the difference of the added fiber, the board is divided into a warm asbestos board and a non-asbestos board.

Fiber cement pressure plate: the fiber cement pressure plate is mainly characterized in that the fiber cement pressure plate is formed by pressing a special press in the production process, has higher density, higher waterproof, fireproof and soundproof performances and stronger bearing, bending and impact resistance, and the performance of the fiber cement pressure plate mainly depends on the pressure of the press except raw materials, a formula and a process.

The cement concrete is commonly used in the building nowadays, and the precast cement concrete plates are mostly used, but when the precast cement plates are used, the whole sound insulation effect is poor due to relatively high hardness, and the requirement of the quiet environment required by work and study in the market is not met.
