Description
Technical field
The present invention relates to wood processing field, more particularly to a kind of timber of furfuryl alcohol polymer dipping.
Background technology
Improved wood is by being impregnated first with the polymerizable liquid of appropriate amount to wood sample, after dipping, to wood
Material sample is heated, so that the polymerizable compound is polymerize and produced in wood cell wall.
The mechanism of timber pickling is that the resin of low molecule amount is impregnated in timber, and resin gathers to each other under certain condition
Close, or Hydrogenbond or chemical bond are formed with the hydroxyl in timber, insoluble polymer is generated in cell membrane, reduces wood
Hydroxyl quantity in material, that is, the hydrophily of timber is reduced, so as to resist sorption of the cell membrane to moisture；Resinous polymer, which becomes, to be made
Cell membrane rushes swollen increase-volume, has the function that to resist cell membrane shrinkage；In addition, the density of processing material is also improved.Therefore,
Dimensional stability, the wet effect of resistance, Perishing prevention and termite resistance energy, the mechanical strength performance for carrying out the timber after impregnation obtain
, also can be durable in use without paint protection to significantly improving.
And toxic reagent would generally be used Wooden modifying in the prior art, environment and human body can be damaged, and
The mechanical strength of timber is relatively low after processing.
