Abstract

The invention discloses an environmentally-friendly ecological plate. The environmentally-friendly ecological plate comprises tobermorite, wood pulp fibers, expanded vermiculite, hydrated negative ionpowder, a silane coupling agent, a stabilizer and an additive. Compared with ecological plate in the prior art, the environmentally-friendly ecological plate of the invention has the following advantages: asbestos-free and formaldehyde-free natural pollution-free materials are adopted, so that the environmentally-friendly effect is achieved; a certain amount of a surface treating agent is added,so that the mechanical properties of the ecological plate are improved; addition of a certain amount of the negative ion powder promotes synthesis and storage of vitamins in human bodies, and plays agreat role in the vital movements of human and other organisms; and the heat conduction coefficient of the environmentally-friendly ecological plate can be reduced to 0.2 or below, so the ecologic plate has an excellent heat insulation performance, accords with the national industrial policy of energy saving and heat insulation, has advantages in the aspects of energy saving and environmental protection, and has a very wide application prospect.

Description

Technical field [0001] The invention relates to the technical field of calcium silicate boards, in particular to an environmentally friendly ecological board. Background technique [0002] As a new type of green building material, calcium silicate board not only has the functions of traditional gypsum board, but also has superior fire resistance, moisture resistance, and long service life. It is widely used in ceiling ceilings and partition walls of industrial and commercial engineering buildings, home decoration , Furniture linings, warehouse sheds, network floors, tunnels and other indoor engineering wall panels. [0003] Due to the large amount of raw minerals and wood fiber materials used in the preparation of these existing calcium silicate boards, it is not conducive to the protection of natural resources such as raw ore and wood. At the same time, the existing calcium silicate boards still have poor mechanical properties. Therefore, it needs further research. Summary of th...
