Abstract
The invention relates to a production method of a high-temperature heating modified rubber wood floor, wherein rubber wood is sawn into wood beams or billets, the wood beams or billets are subjected to insect and termite prevention treatment, drying, carbonization and wood conditioning, the stress and the water content are balanced, and subsequent processing is conducted to obtain the rubber wood floor. The rubber wood is subjected to high temperature heating modified treatment and termite prevention treatment, the manufactured carbonized rubber wood floor is stable in size and excellent in stability and can resist corrosion by moths and termites, the produced carbonized rubber wood solid floor can be used indoors in both the humid south and the dry north, the problem that the solid floor is not easily made in a large width from the rubber wood is solved, and the additional value of the rubber wood is increased. Meanwhile, due to the adoption of the process of subdividing a sheet after carbonizing the wood beams, the problems of large the bending deflection, large reserved allowance in the thickness direction and large loss, resulting from the fact of direct drying and carbonizing of the sheet, can be solved, and the outturn percentage is increased.
Description
Technical field:
The invention belongs to Wood Science and Technology field.Relate to a kind of production method of high-temperature hot modified rubber timber floor, be specifically related to a kind ofly carry out insect protected and heat modification process, machining, covering with paint to rubber wood timber and be applied to the method for producing solid wooden floor board.The high-temperature hot modified rubber timber floor of manufacture of the present invention has the feature of insect protected, dimensionally stable, the tropical precious hardwood that is similar in color.
Technical background:
Rubber tree (Hevea brasiliensis) is extensively planted in south China and Southeast Asia, every year because upgrading the rubber wood timber produced more than 1000 ten thousand steres.Rubber wood timber belongs to diffuse porous wood, easily processes, and texture is pleasing, and being widely used in woodworks such as making furniture, integrated timber finger-jointed plate, toy at present, is important artificial forest merchantable timber.Due to artificial cultivation, arboreal growth is very fast, timber contains a certain proportion of reaction wood, its heart sapwood performance variation is larger, simultaneously due to the impact of rubber tapping on trees xylem, rubber wood timber is more containing knot, black line, and the solid wooden floor board volume recovery in the past adopting rubber wood timber to produce is lower, current rubber wood timber is less directly applies to solid wooden floor board field, and what market can be seen is rubber wood timber veneer overlay composite floor board.
The timber (being commonly called as " carbonized wood ") produced by high-temperature hot method of modifying can improve appearance luster, can improve dimensional stability again.The advantages such as the floor adopting carbonized wood to produce has good stability of the dimension, not yielding are (see CN 100418715C; CN 100392200C), improve serviceability.But rubber wood timber because of containing up to about 8% polysaccharide and the protein such as starch, compared with other timber, apt to rot, go mouldy, damage by worms, through charing process, can antiseptic property be improved, but prevent termite performance from not improving, test shows, for the artificial forest wood such as rubber wood timber and masson pine (Li Xiaowen, forest-science, 2012; Ma Xingxia, timber industry, 2009), more subject to the erosion of termite moth after charing, its sheet material uses in areas such as south Chinas still exists serious termite hidden danger.
Summary of the invention:
The object of the invention is the production method that a kind of high-temperature hot modified rubber timber floor is provided for the deficiencies in the prior art, first rubber wood timber is carried out insect protected and heat modification process, regenerative ratio solid wooden floor board.There is termite-proof, dimensionally stable, the outer appearnce feature like tropical famous and precious hardwood.
Object of the present invention is achieved through the following technical solutions:
A production method for high-temperature hot modified rubber timber floor, comprises the steps:
1), rubber wood timber log saw is made flitch or blank;
2), by flitch or stacks of blanks insert application of vacuum tank, with the boride aqueous solution for treatment fluid vacuum pressure impregnating, carry out the termite-proof process of insect protected;
3), the flitch after termite-proof for insect protected process or blank are dried to moisture content≤30%; Preferably the flitch after termite-proof for insect protected process is dried to moisture content be 15% ~ 30%.
4), the flitch after oven dry or stacks of blanks are inserted charing treatment facility, be warming up to 40 ~ 70 DEG C of insulations 0.5 ~ 10 hour, in 1 ~ 48 hour, timber is warming up to 100 DEG C, temperature-rise period controls wet-bulb depression≤15 DEG C, in 1 ~ 24 hour, be warmed up to 101 ~ 135 DEG C drying is carried out to timber, 140 ~ 220 DEG C of charings 0.5 ~ 10 hour is warmed up in 3 ~ 15 hours, carbonization process passes into steam protection timber, after having carbonized, stop heating, continue to pass into steam and atomized water cooling damping is 6% ~ 10% to moisture content, draw off;
5), charing flitch or blank health, equilibrium stress and moisture content, be charing rubber wood timber blank according to floor specification by flitch subdivision with multiple blade saw, block, sanding, mortice opening, rubber wood timber floor made by paint; Or directly blocked by blank, sanding, mortice opening, rubber wood timber floor made by paint.
Described boride is one or more in the borides such as ammonium pentaborate, sodium fluoborate, boric acid, sodium perborate, sodium tetraborate, kodalk and eight Boratexes.
Moulding pressure>=the 0.3MPa of described application of vacuum tank, pressing time is 0.5 ~ 10 hour, controls the boron equivalent>=0.2kg/m in flitch or blank
3.Be preferably the moulding pressure 0.3 ~ 2.0MPa of described application of vacuum tank, control the boron equivalent 0.2 ~ 30kg/m in flitch or blank
3.The moulding pressure being further preferably described application of vacuum tank is 0.5 ~ 2.0MPa, controls the boron equivalent 2 ~ 20kg/m in flitch or blank
3.
In step (4), generally draw off when Wood temperature is cooled to 30 ~ 80 DEG C.
The preferred technical scheme of the present invention is: directly rubber wood timber log saw is made flitch, carry out the termite-proof process of insect protected, dries, and charing, health, equilibrium stress and moisture content, obtain rubber wood timber floor through following process.After rubber wood timber log saw being made the termite-proof process of flitch insect protected, dry, the technique of subdivision thin plate again after charing, decrease blank convection drying, charing, flexural deformation is large, and the pre-made allowance of thickness direction is large, and the problem that loss is many, improves volume recovery.In addition before charing, only need conventional drying to moisture content to be 15% ~ 30%, residual moisture carbonization process is dry by high temperature drying stage fast speed, can reduce timber conventional drying process time and energy resource consumption, reduce costs.
Beneficial effect of the present invention:
The present invention carries out high-temperature hot modification to rubber wood timber, and carry out termite-proof process, the charing rubber wood timber floor excellent size stability manufactured, moth and the erosion of termite moth can be resisted, the charing rubber wood timber solid wooden floor board produced can in the indoor use in the south of humidity and the dry north, overcome the problem that rubber wood timber not easily makes large format solid wooden floor board, add the added value of rubber wood timber.Meanwhile, adopt the technique of subdivision thin plate again after flitch first dry, charing, decrease blank convection drying, charing, flexural deformation is large, and the pre-made allowance of thickness direction is large, and the problem that loss is many, improves volume recovery.
