Problems solved by technology

Although the traditional "trialdehyde" glue flame-retardant plywood has basically met the requirements of the building decoration industry for fire resistance, but in the case of high-temperature radiation or direct burning of other combustibles, the "trialdehyde" glue inside the board will decompose and release A large amount of toxic and harmful formaldehyde gas will also cause great harm to the human body

Embodiment 1

[0025] Example 1: A formaldehyde-free flame-retardant plywood produced by using large protein glue, the plywood includes flame retardant soaked veneer, flame retardant mixed with soybean protein glue, glue coating, pre-pressing, hot pressing, sanding, veneering, polishing And other processes, in which in order to ensure the flame retardancy of the wood board, both the veneer and the adhesive are combined with the flame retardant, the water-soluble non-halogen flame retardant is used to soak the veneer, and the insoluble powder flame retardant is used for the adhesive mixture, so that the combination method can be more effective Guarantee the flame retardancy and water resistance of plywood.

[0026] The flame retardants used for soaking veneer are water-based non-halogen flame retardants, including monoguanidine phosphate, diguanidine phosphate, ammonium polyphosphate with a degree of polymerization lower than 20, silane coupling agent, soluble borate, potassium molybdate, wate...

Embodiment 2

[0033] Embodiment 2: as figure 1 As shown, a formaldehyde-free flame-retardant plywood produced by using large protein glue, the first layer of transverse bark 1 is connected to one side of the first layer of longitudinal bark 2, and the other side of the first layer of longitudinal bark 2 is connected to the second layer A glue layer 3, the other side of the first glue layer 3 connects the second layer of longitudinal bark 4, the other side of the second layer of longitudinal bark 4 connects the second layer of transverse bark 5, the second layer of transverse bark 5 The other side of the third layer of longitudinal bark 6 is connected, the other side of the third layer of longitudinal bark 6 is connected to the second glue layer 7, and the other side of the second glue layer 7 is connected to the third layer of longitudinal bark 9, the second The other side of the three layers of longitudinal bark 9 is connected to the third layer of transverse bark 8 .

Abstract

The invention discloses formaldehyde-free flame-retardant plywood produced by using large albumen glue and a preparation method, and belongs to the technical field of artificial boards. A first layer of transverse bark is connected with one side of a first layer of longitudinal bark, the other side of the first layer of longitudinal bark is connected with a glue layer, the other side of the glue layer is connected with a second layer of longitudinal bark, and the other side of the second layer of longitudinal bark is connected with the second layer of transverse bark. The method comprises the following processes: infiltrating a wood veneer with a flame retardant, mixing the flame retardant with soybean protein glue, performing gluing, performing pre-pressing, performing hot-pressing, performing sanding, performing veneering, performing polishing and the like. In order to ensure the flame retardance of a wood board, the wood veneer and an adhesive are combined with the flame retardant, the wood veneer is infiltrated by a water-soluble halogen-free flame retardant, the adhesive is mixed with an insoluble powder flame retardant, and the flame retardance and the water resistance of the plywood are effectively ensured. The plywood has the advantages that the flame retardance of the board is reserved, the problem that a traditional flame-retardant board is damaged by formaldehyde of an aldehyde-containing adhesive when the plywood is subjected to high temperature is also solved, and besides, excellent water resistance of the soybean protein glue also ensures the water resistance and moisture resistance of the board.

Description

technical field [0001] The invention relates to a formaldehyde-free flame-retardant plywood produced by using large protein glue and a preparation method thereof, belonging to the technical field of wood-based panels. Background technique [0002] Protecting the environment and pursuing formaldehyde-free has become a hot topic in the wood-based panel industry. Among them, artificial wood panels, especially plywood-based flame-retardant panels, account for an increasing proportion of engineering decoration. Inseparable. Although the traditional "trialdehyde" glue flame-retardant plywood has basically met the requirements of the construction and decoration industry for fire resistance, but in the case of high-temperature radiation or direct burning of other combustibles, the "trialdehyde" glue inside the board will decompose and release A large amount of toxic and harmful formaldehyde gas will also cause great harm to the human body. [0003] Therefore, plywood that is aldeh...
