Contracting removes high-boiling components, butylene glycol is hydrogenated to butanediol, and thick tetrahydrofuran is generated after distillation, continues distillation dehydration and takes off
High-boiling components obtain.
Wherein, the organic solvent is absolute ethyl alcohol.
The rosin is acquired from resin tapping seeds masson pine, pinus yunnanensis, pinus khasys or pinus finlaysoniana seeds.
The rosin alcoholic solution is stirred by rosin and organic solvent in the case where temperature is 40 DEG C of water bath conditions, until
To uniform rosin solution, as rosin alcoholic solution.
Preparation method of the present invention for impregnating the rosin furans preservative of poplar includes the following steps：In pine
Furans monomer is added in lipidol solution, carries out microwave treatment after mixing, microwave treatment power is 100-200W, processing time
For 5-10min or so, treatment temperature is 20-30 DEG C, and reaction terminates to obtain rosin furans preservative.
The application of rosin furans preservative in improving poplar durability of the present invention for impregnating poplar.
The method for improving poplar durability, includes the following steps：Cottonwood plank stuff is dried to moisture content and is less than 10%,
Then it is placed in the process tank for filling rosin furans preservative, is warming up to 90-100 DEG C, pressure inside the tank 0.8-
1.2MPa reacts 2.5-3.5 hours in this case, pressure release postcooling 4 hours or more.
Advantageous effect：Compared with prior art, the rosin furans preservative for impregnating poplar of the invention is prepared simple,
Raw material sources are wide, at low cost, nonhazardous effect；The heavy metal chemical preservation of conventional high pollution can effectively be replaced, reduce weight
Metallic pollution, and favorable anti-corrosion effect can effectively improve the durability of poplar；It is soaked by the rosin furan polymer preservative
Stain can change the physics and chemical property of poplar material, and poplar material corrosion resistant performance is good, resistance leachability is good to making, and is free of
Heavy metal, Anti-moth-eating, antimycotic, rotproof performance are reinforced.
