Background
Plywood, also known as plywood, is one of the common materials used in furniture, and usually its crown plywood skins and inner plies are symmetrically arranged on both sides of a central layer or core. Three-ply boards, five-ply boards and the like are commonly used. The plywood can improve the utilization rate of the wood and is a main way for saving the wood.
The multilayer board is a three-layer or multi-layer plate material formed by rotary cutting wood sections into single boards or slicing battens into thin wood and gluing the thin wood with adhesives, and is usually formed by gluing odd layers of single boards and mutually vertical fiber directions of adjacent layers of single boards.
The multilayer board is produced through the processes of making inner layer pattern, printing and etching to form single-sided or double-sided base board, setting the base board between layers, heating, pressurizing and adhering, and drilling holes in the base board.
At present, although the multilayer board has better flame resistance, the flame resistance of the produced board is poor due to the technical short board in production.

Melamine cyanurate
The melamine cyanurate is a salt synthesized from melamine and cyanuric acid, belongs to a nitrogen series flame retardant, and has two forms of powder and granule. When the polyamide foam flame-retarded with this product is burned, the resulting carbon foam layer protects the polymer, insulating heat and oxygen. By adding the product, the smoke density and toxic gas of the polymer can be greatly reduced, and simultaneously, irritant hydrogen halide gas is not generated.
Antimony trioxide
Antimony trioxide (chemical formula: Sb)2O3) Is an inorganic compound. The natural product is named as antimony white, commonly named as antimony white and white crystalline powder. Melting point 655 deg.C, boiling point 1550 deg.C. Dissolving in sodium hydroxide solution, hot tartaric acid solution, tartaric acid hydrogen salt solution and sodium sulfide solution, and slightly dissolving in water 370 + -37 μ g/L, dilute nitric acid and dilute sulfuric acid. Has carcinogenic potential. The preparation method comprises a dry method and a wet method, is mainly used for white pigment, paint and plastics, and can play a role in pigment and flame retardance.
Silica nanoparticles
