Problems solved by technology

However, the physical properties of flame-retardant wood-based panels produced by vacuum pressurization or immersion will be seriously damaged, and their flame-retardant components will also volatilize within a certain period of time, which will bring great hidden dangers to safety.
General flame-retardant wood-based panels will produce harmful substances in the process of production and use, which will cause harm to the environment and human life.
On the other hand, the safety performance of the existing wooden flame-retardant panels is extremely unstable, and it is difficult to meet the fire-proof standards.

Abstract

The invention provides a multilayer flame-retardant wood-based composite board, comprising at least one group of flame-retardant sandwich boards. Each flame-retardant sandwich board comprises an inorganic fireproof substrate layer and two wood single-board layers symmetrically arranged at two sides of the inorganic fireproof substrate layer. The layers are bonded together through a water-soluble flame-retardant adhesive which comprises magnesium sulfate, magnesium chloride, polyvinyl alcohol, a boron-phenol mixture, magnesium oxide, phosphate, ammonium polyphosphate and calcium formate. The multilayer flame-retardant wood-based composite board has good flame retardation, smoke suppression, nontoxicity, corrosion resistance and insect resistance and is applicable to the fields of decoration of a variety of buildings and furniture manufacturing. The invention also provides a manufacturing method for the multilayer flame-retardant wood-based composite board. The manufacturing method mainly employs cold-pressing and hot-pressing molding processes for shaping and curing and is simple, green and free of pollution.

Description

technical field [0001] The invention relates to a composite board and a manufacturing method thereof, in particular to a multilayer flame-retardant wood-based composite board and a manufacturing method thereof. Background technique [0002] Wood-based flame-retardant wood-based panels generally achieve the purpose of flame-retardant by vacuum-pressurizing or soaking the flame-retardant. However, the physical properties of flame-retardant wood-based panels produced by vacuum pressurization or soaking will be seriously damaged, and the flame-retardant components will also volatilize within a certain period of time, which will bring great hidden dangers to safety. Generally, flame-retardant wood-based panels will produce harmful substances in the process of production and use, which will cause harm to the environment and human life. On the other hand, the safety performance of the existing wooden flame-retardant boards is extremely unstable, and it is also difficult to meet fi...
