Description
Technical field
The present invention relates to fiberboard, particularly a kind of preparation method of compound flame retardant fibre board.
Background technology
The method for preparing flame retardant fibre board at present mainly has plate face cladding process and additive process.Additive process, i.e., into before plate
The flame retardant treatment of progress is that fire retardant and fiber are carried out simple mechanical agitation physical blending or fire retardant is sprayed at fibre
In dimension, it is then pressed into plate.Though the method is so that entire plank all has flame retardant effect, amount of flame-retardant agent is big, and with fire-retardant
The addition of agent, the internal bond strength of plank reduces, and then influences the mechanical property of plank, limits the use of plank；Cladding process, i.e.,
In fiber into after plate, in the uniform applying fire retardant of fibreboard surface or anti-flaming dope, flame retardant fibre board is prepared.Though the method
Outer layer protection, gas to directly fire-retardant effect, dosage is few, but there is also durability it is poor, spray uneven and adhesive glue
The problem of viscosity can be with retardant load level relationship etc., and once fire-retardant surface layer is destroyed, there is no flame retardant effects for entire plank.
It is on the contrary very universal using single additive process to flame retardant fibre board at present, i.e., into the fire-retardant place carried out before plate
Reason is that fire retardant and fiber are carried out simple mechanical agitation physical blending or fire retardant is sprayed on fiber, then presses
Flame retardant fibre board is made in manufactured Board.This method can affect to the mechanical property of fiberboard, with adding for fire retardant
Enter, the internal bond strength of product can be reduced, and then reduce the mechanical property of plank, limit the use of plank.In addition, cost
Height, only fire retardant are uniformly mixed with fiber, just can guarantee that entire plank has flame retardant property, so the addition of fire retardant
Greatly, so cost is higher.
It is current that also flame retardant fibre board is rarely reported using addition inside fire retardant with externally coated, and using single
Cladding process it is also common, i.e., in the uniform applying fire retardant of fibreboard surface or anti-flaming dope, prepared into after plate in fiber
Flame retardant fibre board.This method is poor there are durability, because the adhesion between plate face coating and fiberboard is poor, with used in fiberboard
The growth of time, coating slowly peel off, and cause durability poor, once fire-retardant surface layer is destroyed, there is no fire-retardant effects for entire plank
Fruit.In addition, the decoration performance of coating thickness, also influence plank.It is restricted the application of plate.
Therefore the improvement in flame retardant fibre board production and innovation are the technical issues of must solving.
Invention content
For the above situation, to overcome the defect of the prior art, the purpose of the present invention is just to provide a kind of compound fire-retardant
