Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of fabricated material, especially relates to a fabricated multifunctional metal veneer integrated board taking gypsum fiber board as base material. BACKGROUND

[0003] The metal veneer integrated board taking particle board, shaving board, woodwork board and multi-layer board as base material cannot reach the requirement of A1 non-combustible material according to the classification of GB8624-2012 Building Materials and Products Combustion Performance Grade. A large amount of adhesive glue needs to be added when preparing the wood-based board substrate, which leads to high formaldehyde emission and VOC emission of the board. According to the classification standard of GB / T 39600-2021 Emission of Formaldehyde from Wood-based Panels and Their Products, it can only reach E0 and environmental protection level.

[0004] The metal veneer integrated board taking calcium silicate board as base material has large dust and big wear of blade when cutting due to the hard texture and brittleness of the board containing silica. The brittleness of the board makes the metal veneer integrated board taking calcium silicate as base material easy to crack when self-tapping nails are used, which is not suitable for dry hanging installation. The large shrinkage of the base material easily causes shrinkage cracks. The metal veneer integrated board taking glass magnesium board as base material easily appears frosting phenomenon and has poor water resistance and easy warping deformation due to the magnesium chloride in the base material.
