Abstract
A kind of method that the invention discloses Wooden modifying, comprises the steps: 1) timber to be modified is positioned in immersion can, carry out suction process when heating, air in this immersion can completely or almost completely is excluded；2) maintaining the vacuum state of step 1), immersion can is cooled to less than 25 DEG C, is incorporated in immersion can by the Wood modifier of 05 DEG C, until being totally submerged by timber, then pressurizes；3) after being emptied by impregnation liquid, lumber kiln dried stage by stage delivered to by evacuation heating precuring timber, 55 DEG C are dried to moisture content less than 30%, 65 DEG C are dried to moisture content less than 20%, and 80 DEG C are dried to moisture content less than 15%, and 120 DEG C are dried to moisture content less than 8%；5) dried timber carries out thermosetting compression process, the method using this Wooden modifying on hot press, and the volume rate of body weight gain of timber is greatly enhanced.
Description
Technical field
A kind of method that present invention relates particularly to Wooden modifying.
Background technology
Timber is widely used in as a kind of renewable environmental friendliness shaped material and lives closely bound up place with people, as
Building, furniture etc., it is easily processed, and carrying capacity of environment is little, be steel, cement incomparable, but, timber as one organic
Natural macromolecular material, exists inflammable, perishable, easily damage by worms, size is unstable, physical and mechanical property energy consumption is low problem, this
A little problems make the application of timber be very limited, in order to overcome the disadvantages mentioned above of timber, people think timber impregnates change its
Functional improvement reagent of character, such as, fire retardant, preservative, antifungus agent and the resin etc. of its mechanical property of change.
In Wooden modifying of the prior art, using vacuum impregnation to process, the purpose of do so, is in order to as far as possible
The air being present in timber capillary tube is extracted out and goes, then, be injected in timber impregnating liquid under stress, due to when wood
In material, air cannot drain, and the internal pressure of wood cell wall and external pressure pressure reduction to a great extent is the least, thus timber
The ability of absorption impregnating fluid.
Summary of the invention
A kind of method that Wooden modifying is provided of the present invention.
In order to solve the problems referred to above, the technical solution adopted in the present invention is such, a kind of method of Wooden modifying, bag
Include following steps:
1) timber to be modified is positioned in immersion can, carries out suction process, by this immersion can hollow when heating
Gas completely or almost completely excludes, and suction time is 2-4 hour, and vacuum is 2400-2600Pa, and temperature is 100-
120℃；
2) maintain the vacuum state of step 1), after immersion can is cooled to room temperature, the Wood modifier of 0-5 DEG C is incorporated into and impregnates
In tank, until being totally submerged by timber, then pressurizeing, the process time is 6-8 hour, pressure >=1.0MPa；
3) evacuation heating precuring 0.5-1 hour after being emptied by impregnation liquid, vacuum is 2400-2600Pa, and temperature is 45-
50℃；
4) lumber kiln dried stage by stage delivered to by the timber after precuring, and 55 DEG C are dried to moisture content less than 30%, 65 DEG C
Being dried to moisture content less than 20%, 80 DEG C are dried to moisture content less than 15%, and 120 DEG C are dried to moisture content less than 8%；
5) dried timber carries out thermosetting compression process on hot press, and pressure is 9-11MPa, and temperature is 185-200 DEG C.
Preferably, step 2) in pressure be 1.0-1.5MPa, step 2) in immersion can be cooled to 0-5 DEG C.
Preferably, after the air that Wood modifier is contained in getting rid of it under vacuum, it is re-introduced in immersion can.
The Wood modifier that Wood modifier of the present invention is known in the art.
Beneficial effect: 1, the present invention is in a heated state, timber can expand, now evacuation under state, air in timber
Discharging all or almost all, after cooling, then with after cold modifying agent immersion, in timber, remaining air compresses and causes true
Dummy status, so borrows external air pressure fall Wood modification agent to be pressed onto in timber, improves and impregnate effect, the volume weightening finish of timber
Rate is greatly enhanced.
2, the pre-heat cure of the present invention decreases timber and moves to the outflow of Wood modifier during dry kiln.
3, precuring of the present invention uses and is dried stage by stage, saves while energy, Wood modifier coagulation result good and
Uniformly.
