Test material
Fire retardant is configured to the aqueous solution of mass fraction 8%
Pine, specification (length × width x thickness) 4000mm × 250mm × 50mm, moisture content about 6%.Pine is more containing rosin,
And sapwood is few, heartwood is more, under identical fire retardant treatment process, the fire resistance of sapwood is more excellent, therefore produces in heartwood examination
Sample.Experimental rig
Pyris1 type thermogravimetric analyzers；FTTStandard type cone calorimetries；Vacuum pressure impregnating processing unit etc..Examination
Test design and method
According to pre-stage test result, control sample is used as using water process material.
Sample, is handled according to following technique by every group 10 pieces：Examination material is processed into specification (length × width x thickness) is
100mm × 100mm × 10mm sample, takes after being dried to constant weight at 50 DEG C and (being spaced 5h 2 inferior quality measurement errors≤0.01g)
Go out, it is standby.
According to early-stage Study result, and in view of the more difficult impregnation process of pine, to obtain higher carrying drug ratio, using vacuum
Impregnating by pressure facture.Sample is immersed in below liquid level, and moved in vacuum tank.Initial vacuum degree 0.1MPa, keeps 15min；
0.3MPa is forced into, 30min is kept；Recover to normal pressure, take out sample, dried to constant weight at 50 DEG C.
Fire resistance reference standard ISO5660-1：2002《The release of Reaction to fire experiment heat, smoke-producing amount and mass loss speed
Rate part 1：HRR (Cone calorimeter)》, detect the HRR of sample.Every group of 2 samples are averaged.Examination
Control gauge lattice
(length × width x thickness) 100mm × 100mm × 10mm
Experiment can be seen that
Embodiment 1- embodiments 4, it is seen that SAPO-5 powder and Sb2S3 match the emulsification-Sb2S3/SAPO- for preparing
The influence of 5 flame retardant effects is very big, and the flame retardant effect that wherein embodiment 1 is matched is best,
Embodiment 5-15 can be seen that can be significantly in the interval interior a certain amount of Sulphur Black 2BR of addition of certain proportioning
Improve flame retardant effect,
Substantially in emulsification-Sb2S3/SAPO-5 and Sulphur Black 2BR in 8-10:In 1 interval range, average HRR
It can be greatly lowered, it is mainly synergy and significantly can promote to form polyaromatic network structure, and foamed char is porous,
The carbon residue of wood formation is form compact and stable.
But other ratios, its average HRR is raised on the contrary, is played suppression and is formed polyaromatic network structure, is unfavorable for
Flame retardant effect, it is seen that its ratio plays very important effect, it is excessive or very few not utilize promotion to form polyaromatic netted
Structure, foamed char is porous, and the carbon residue of wood formation is form compact and stable.
