Description

Wood fire retardant and wood veneer flame-proof processing technique
Technical field
The present invention relates to a kind of wood fire retardant and Wood fire retardant treatment process.
Background technology
Timber is a kind of combustible material, has very big fire risk.Along with the continuous increase of furniture, indoor decorating and even building structure consumption of wood, and the property and the hazard to person of constantly concentrating fire to cause of urban population increase day by day.Timber and woodwork fireproof necessity are self-evident, the progress of application of advanced analysis instrument in recent years and related science technical field, and the research that has driven the fire-retarding of wood field makes great progress, and begins to take shape fire-retarding of wood theory and technology system.
Glued board is to use one of main wood materials very widely in indoor decorating and other architectural engineerings, but present stage China's glued board flame treatment on take whole plate to handle always, exist outstanding two large problems to be:
1. the finished product glued board very easily causes serious degumming phenomenon through operations such as immersion, vacuum, pressurizations in the flame treatment process.
2. the finished product glued board particularly slab influenced by glue and multi-layer sheet thickness etc., fire retardant is difficult for even depth of penetration, does not influence flame retardant effect thereby the fire retardant uptake reaches standard.
Summary of the invention
The objective of the invention is provides a kind of wood fire retardant that makes timber reach fire protecting performance in order to solve deficiency of the prior art.
For realizing above purpose, the present invention is achieved through the following technical solutions:
A kind of wood fire retardant is characterized in that, and is composed of the following components by weight percentage: borax 8~12%; Boric acid 8~12%; Dicyandiamide 8~12%; Diammonium hydrogen phosphate 33~38%; Ammonium sulfate 33~38%.
Preferably, composed of the following components by weight percentage: borax 9.5~10.5%; Boric acid 9.5~10.5%; Dicyandiamide 9.5~10.5%; Diammonium hydrogen phosphate 34~36%; Ammonium sulfate 34~36%.
Each component is mixed according to proportioning, promptly can be made into wood fire retardant.
Another object of the present invention provides a kind of wood veneer flame-proof processing technique, may further comprise the steps: A, wood single-plate being positioned in the process tank, is 0.09~0.1MPa with degree of being evacuated in the process tank, keeps 15~30 minutes; B, will be made into fire retardant according to claim 1 or 2 described proportionings after, the water-soluble solution of making injects solution in the process tank, keeps 50~70 minutes down in 0.15~0.25MPa pressure, discharges solution; C, be 0.09~0.1MPa, kept 20~40 minutes degree of being evacuated in the process tank; Can obtain the fire retarding wood veneer.
Another object of the present invention provides a kind of fire-retardant plank that adopts aforesaid veneer flame-proof processing technique to make.
Another object of the present invention provides a kind of fire-proof plywood treatment process, carries out the veneer flame treatment, after the veneer drying again the veneer gluing, with multilayer veneer glue laminated, make fire-proof plywood; Described flame treatment may further comprise the steps: A, wood single-plate being positioned in the process tank, is 0.09~0.1MPa with degree of being evacuated in the process tank, keeps 15~30 minutes; B, will be made into fire retardant according to claim 1 or 2 described proportionings after, the water-soluble solution of making injects solution in the process tank, keeps 50~70 minutes down in 0.15~0.25MPa pressure, discharges solution; C, be 0.09~0.1MPa, kept 20~40 minutes degree of being evacuated in the process tank.
Another object of the present invention provides a kind of fire-proof plywood that adopts aforementioned fire-proof plywood treatment process to make.
Wood fire retardant among the present invention, preparation can make timber reach fire resistance easily, can reach various request of national standard; The plank that veneer flame treatment in the present invention is crossed, fire resistance can reach various request of national standard; Fire-proof plywood among the present invention uses the fire retardant among the present invention, after first veneer is handled again glue laminated become whole plate, fire resistance is better than the glued board that the whole again plate resistance combustion of first glue laminated is handled.
