Method, and in particular to a kind of to be used to impregnate rosin furans preservative of poplar and its preparation method and application.
Technical background
In today of timber resources growing tension, how fast-growing forest timber is effectively utilized, make it have more wide answer
It is to alleviate the nervous effective ways of timber resources with scope.Poplar material is poor, easily damages by worms rotten, and existing poplar wood preservation is main
Be by impregnate anti-corrosion agent and destroy mushroom life condition, suppress domestomycetes breeding and existence and realize.In recent years
Come, poplar wood working industry is handled fast-growing forest timber by a variety of methods, to obtain ideal material, Yi Jifang
Damage by worms, prevent rotten performance.Processing method is a lot, but the maceration extract used that exists that these methods have is polluted to environment, state
Inside and outside conventional timber preservative mainly has CCA, copper chromium boron (CCB), fluorine chromium phenol arsenic (FCAP), ammonical copper arsenite (ACA), acidity
Copper chromate (ACC) etc., some handling process route length, cost are high.Rich in phenols, organic acid, furans, alcohols etc. in rosin
Compound, with certain bactericidal effect, also has application potential, but still lack corresponding technical side at present in corrosion-resistant field
Method.
The content of the invention
Goal of the invention:The problem of existing for prior art, the present invention provides a kind of rosin furans for being used to impregnate poplar
Preservative.The rosin furans preservative, raw material sources are wide, can effectively replace the heavy metal chemical preservation of conventional high pollution,

Contracting, removes high-boiling components, and butylene glycol is hydrogenated to after butanediol, distillation to generate thick tetrahydrofuran, continues distillation dehydration and de-
High-boiling components are obtained.
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.
The preparation method of the present invention for being used to impregnate the rosin furans preservative of poplar, comprises the following steps:In pine
Furans monomer is added in lipidol solution, microwave treatment is carried out after being well mixed, microwave treatment power is 100-200W, processing time
For 5-10min or so, treatment temperature is 20-30 DEG C, and reaction end obtains rosin furans preservative.
Application of the rosin furans preservative of the present invention for being used to impregnate poplar in poplar durability is improved.
The method for improving poplar durability, comprises the following steps:Cottonwood plank stuff is dried to moisture content less than 10%,
Then in the process tank for being placed on filling rosin furans preservative, 90-100 DEG C is warming up to, pressure inside the tank is 0.8-
1.2MPa, reacts 2.5-3.5 hours in this case, is cooled down more than 4 hours after pressure release.
Beneficial effect:Compared with prior art, the rosin furans preservative for being used to impregnate poplar of the invention is prepared simply,
Raw material sources are wide, and cost is low, nonhazardous effect;The heavy metal chemical preservation of conventional high pollution can effectively be replaced, weight is reduced
Metallic pollution, and favorable anti-corrosion effect, can effectively improve the durability of poplar;Soaked by the rosin furan polymer preservative
Stain can change the physics and chemical property of poplar material, so that poplar material corrosion resistant performance is good, resistance leachability is good, and be free of
Heavy metal, Anti-moth-eating, antimycotic, rotproof performance are strengthened.
