Abstract

The invention discloses a formaldehyde-zero ecological plate. The formaldehyde-zero ecological plate is prepared from the following raw materials in parts by weight: 1 to 95 parts of wood flour or wood shavings, 1 to 95 parts of cellosilk, 1 to 50 parts of an organic adhesive, 0.1 to 50 parts of an inorganic adhesive, 0 to 20 parts of aluminum powder, 0.01 to 5 parts of a fire-proofing agent and 0.01 to 2 parts of a water-proofing agent. The invention also discloses a preparation method of the formaldehyde-zero ecological plate. According to the formaldehyde-zero ecological plate disclosed bythe invention, recycled abandoned plates can be reasonably utilized, and the prepared formaldehyde-zero ecological plate has the characteristics of light weight, high compression strength, good fireproofness and waterproofness, zero formaldehyde emission and the like.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a formaldehyde-free ecological board and a preparation method thereof. Background technique [0002] China's particleboard production experience is a repeated process of rising in the 1980s, falling in the 1990s, and rising again in 2000. After the particleboard was abandoned by the market due to poor quality and other reasons, many particleboard companies learned their lessons and introduced foreign advanced production lines and improved technology. The quality of Chinese particleboard has improved significantly, and it has been accepted by the market again. Enterprises have re-selected particleboard as raw material. In recent years, the demand for particleboard in China has been increasing year by year. With the increasing demand for particleboard at home and abroad, and the country's introduction of preferential policies to encourage the development of the wood-ba...
