Abstract
The invention discloses flame retardant timber with the flame retardant characteristic and a preparation method of the flame retardant timber. The flame retardant timber comprises timber and a flame-resistant material and is characterized in that the flame retardant material comprises diammonium hydrogen phosphate, ammonium dihydrogen phosphate and a 5A molecular sieve, wherein the concentration is 15-20%. The flame retardant timber prepared with the formula and the method can be applied to the fields including furniture, packaging, construction, indoor and outdoor decoration and the like.
Description
Technical field
The present invention relates to a kind of manufacture method with the fire retarding wood of flame-retarding characteristic.
Background technology
Timber is widely used in the fields such as furniture, interior decoration and building, but its intrinsic inflammability has limited the range of application of timber.In national < < Code for fire protection design of buildings > >, classify the fire risk of timber as B2 class, i.e. flammable solid.According to the requirement of GB GB20286-2006, finishing and the furniture material of finishing and furniture materials, especially public place have enforceable fire-retardant requirement.How timber, because its inflammability has certain limitation in use, carries out flame treatment to timber, is people's urgent problems.
Summary of the invention
The object of this invention is to provide a kind of fire retarding wood with good flame-retardance energy, further aim of the present invention is to provide a kind of method of making this fire retarding wood.
For achieving the above object, the invention provides following technical scheme: a kind of fire retarding wood, its raw material comprises timber and fire proofing, it is characterized in that: described fire proofing is the mixed solution of diammonium hydrogen phosphate, ammonium dihydrogen phosphate (ADP) and modifier, and this fire proofing concentration is 15-20%.
Described modifier is 5A molecular sieve.
The addition of described modifier is the 1-5% of phosphate weight
The timber of described fire retarding wood for crossing through fire proofing immersion treatment.
Employing molecular sieve is modifier, can improve the fire resistances such as remaining carbon of fire retarding wood.
The present invention also provides a kind of method of preparing above-mentioned fire retarding wood, is specially:
The mixed solution of configuration diammonium hydrogen phosphate, ammonium dihydrogen phosphate (ADP) and modifier, adopts the mode of soaking that timber is put into mixed solution completely, and keeping the temperature of mixed solution is 80 ℃, soaks 2 hours, after being dried, obtains fire retarding wood.
Described modifier is 5A molecular sieve.
The addition of described modifier is the 1-5% of phosphate weight.
In phosphate, add molecular sieve, can improve the rate of body weight gain of phosphate on timber, improve the fire resistance of fire retarding wood.Therefore, use modifier can improve the remaining carbon of fire retarding wood.
The specific embodiment
Fire retarding wood of the present invention, its raw material comprises timber and fire proofing, and described fire proofing is the mixture of phosphate and modifier, and the concentration of this fire proofing is 15-20%.Fire proofing is ammonium dihydrogen phosphate (ADP) and diammonium hydrogen phosphate, and modifier is 5A molecular sieve.Modifier addition is the 1-5% of phosphate weight.The wood raw material that fire retarding wood of the present invention adopts is softwood and broadleaf.
The present invention's modifier 5A molecular sieve used is by SiO
4and AlO
4the crystalline silica-aluminate that tetrahedron is formed by connecting by oxo bridge.5A molecular sieve has the fire-retardant effect of synergistic to expansion type flame retardant, the generation of carbon while being conducive to burn.
Timber is that the moisture content carried is after drying at the timber of 8-12%, according to the size of the fire retarding wood that will produce, configure the phosphate of respective amount and the solution of modifier, timber is put into solution, timber can be immersed in solution completely, and fire proofing concentration is 15-20%, adopts heating to guarantee that solution temperature is 80 ℃, timber pickling was taken out after 2 hours, was after drying finished product.
In fire proofing, add molecular sieve, can improve the rate of body weight gain of phosphate on timber, improve the fire resistance of fire retarding wood.
