Problems solved by technology

[0003] However, due to its own characteristics and appearance, traditional calcium silicate boards are often limited to the above-mentioned ceilings, partitions and other fields, and cannot replace the original density boards in furniture, floors, cabinets and other fields. Existing boards Furniture has the disadvantages of not being able to withstand blisters, being flammable, not easy to relocate, and having a high probability of deformation, and it is difficult to control formaldehyde exceeding the standard, which is harmful to human health. On the one hand, solid wood furniture is expensive, on the other hand, it consumes a lot of forest resources and affects the ecological environment.

Abstract

The invention relates to a calcium silicate board and a preparation method thereof. The calcium silicate board is prepared from 1 or 2 board layers and 1 calcium silicate board layer, and if the 1 board layer exists, the 1 calcium silicate board layer is arranged below the 1 board layer; if the 2 board layers exist, the 1 calcium silicate board layer is arranged between the 2 board layers; the rawmaterials of the board layers comprise wood fiber, polyolefin plastic, mineral filler, a lubricant, an antioxidant, a coupling agent, a titanium dioxide and reinforced fiber; the reinforced fiber issurface modified or non-modified glass fiber, jute fiber or palm fiber; at least one bunch of the reinforced fiber continuously stretches in the length direction of the board layers. The 1 or 2 boardlayers are arranged on the surface of the calcium silicate board, the performance of the calcium silicate board is improved, so that the calcium silicate board is difficult to deform and can be used for making furniture, cabinets and the like, the range of application of the calcium silicate board is enlarged, meanwhile, the raw materials for manufacturing the furniture is saved, and the waste offorest resources is avoided.

Description

technical field [0001] The invention belongs to the technical field of making calcium silicate board materials, and in particular relates to a calcium silicate board and a preparation method thereof. Background technique [0002] Calcium silicate board is made of organic and inorganic materials such as silicon, calcium materials and fibers through a series of production process molding, pressurization, high temperature, high pressure steaming and special technology. It has a long service life, safety and environmental protection, and is Widely used in suspended ceilings and partition walls of industrial and commercial engineering buildings, home decoration, furniture lining boards, billboard lining boards, warehouse shed boards, network floors and tunnels and other indoor engineering wall boards, etc. It is an ideal low-carbon energy-saving , Green environmental protection materials. And the calcium silicate board has excellent waterproof, fireproof and sound insulation pro...
