Problems solved by technology

[0002] At present, decorative boards have been widely used in the decoration of door frames and walls. Decorative boards can make the place decorated look new. However, these decorative boards, such as MDF and plywood, are all composite boards. These decorative boards are made of urea-formaldehyde containing formaldehyde Glue is used as an adhesive. Because formaldehyde is a volatile and toxic gas, users will inhale formaldehyde after living in a renovated house, which will cause harm to the user's body.

Abstract

The fire-resisting water-proofing decorative plate is characterized by that it is made up by adopting plant fibre powder (husk powder, bran powder, wood powder and straw and stalk powder of various crops) as main raw material, using resin powder containing no formaldehyde as adhesive and adding conventional foaming agent, antiaging agent, plasticizer and fire-resisting agent, etc. through a certain preparation process. Said invention also provides its preparation method.

Description

technical field [0001] The invention relates to a decorative material, in particular to a formaldehyde-free fireproof and waterproof decorative board and a preparation method thereof. Background technique [0002] At present, decorative boards have been widely used in the decoration of door frames and walls. Decorative boards can make the place decorated look new. However, these decorative boards, such as MDF and plywood, are all composite boards. These decorative boards are made of urea-formaldehyde containing formaldehyde Glue is used as an adhesive. Because formaldehyde is a volatile and toxic gas, users will inhale formaldehyde after living in a renovated house, which will cause harm to the user's body. Contents of the invention [0003] The object of the present invention is to provide a decorative board with plant fiber powder as the main raw material, free of formaldehyde, fireproof, waterproof, flame retardant, low in cost and its preparation method. [0004] The ...
