Abstract

The invention relates to a production method of a decorative sheet, in particular to a method for producing an atomic oxygen anion flame-retardant formaldehyde-free decorative sheet from agriculture and forestry residues. The method for producing the atomic oxygen anion flame-retardant formaldehyde-free decorative sheet from the agriculture and forestry residues comprises the following steps: (1)conducting biomass modification: conducting surface modification on a biomass powder material; (2) producing a base layer: after 30-50 parts by weight of a biomass powder material subjected to surfacemodification treatment and 50-70 parts by weight of a first magnesium oxychloride cement mixture are fully mixed, conducting micro-foaming and paving to form the base layer; (3) conducting surface layer production and layered paving: producing a second magnesium oxychloride cement mixture, and paving the base layer with the second magnesium oxychloride cement mixture which is used as a surface layer; a ratio of the thickness of the surface layer to the thickness of the base layer is (0.2-0.8):(15-20); and the first magnesium oxychloride cement mixture comprises, in parts by weight, 0.5-4 parts of trisodium phosphate and magnesium sulfate, 10-20 parts of silica powder, 0.1-0.8 part of sodium methylenebisnaphthalene sulfonate, 0.1-0.9 part of 2-(2-[4-(1,1,3,3-tetramethylbutyl)phenoxy]ethoxy)ethanol, 0.1-1 part of calcium formate and the balance magnesium oxychloride cement. The decorative sheet produced through the method for producing the atomic oxygen anion flame-retardant formaldehyde-free decorative sheet from the agriculture and forestry residues has functions of flame retardancy, fireproofing, anion induction and light weight.

Description

technical field [0001] The invention relates to a method for preparing a decorative board, in particular to a method for preparing an oxygen negative ion flame-retardant and formaldehyde-free decorative board by utilizing agricultural and forestry residues. Background technique [0002] Although the total amount of forest resources in my country is growing continuously and the quality is steadily improving, the forest coverage rate in my country is far from the global average level of 31%. 1 / 7, the contradiction between the effective supply of forest resources and the growing timber demand still exists. Finding alternative materials for wood materials is one of the ways to solve the contradiction between the supply of forest resources and the demand for wood. Agricultural and forestry residues are an important biomass resource, which are produced from harvesting to processing of agricultural and forestry crops. The common ones are straw, wood and bamboo processing residues a...
