An a kind of wax emulsion that is used to handle pen usefulness timber
Technical field
The invention belongs to a kind of impregnation of timber agent, a particularly a kind of wax emulsion that is used to handle pen usefulness timber.
Background technology
The processing of plank is extremely important process in wooden pen (as pencil, cosmetic pen etc.) production process.Common method is that plank at first will pass through high-temperature baking, makes lignin and the cellulose oxidation or the part charing of timber, thereby makes the pen cutting laborsaving.In the high-temperature baking plank, also the solid low melt wax can be toasted under 200~250 ℃ of temperature in the roasting plate machine of cylinder with plank, make and infiltrate some hydrocarbon solid molecules in the plank fiber gap.Because the wax that the roasting plate waxdip method of this dry method immerses in plank is very limited, thereby exists a finished product difficult cutting, the problem that the cutting face is coarse.Chinese patent CN 86100189A discloses a kind of medicine method for baking wooden board of wood pencil board.Because this patent does not break away from the roasting plate process of traditional dry method, does not solve a finished product difficult cutting, the problem that the cutting face is coarse.
Summary of the invention
The purpose of this invention is to provide and a kind ofly be used to handle pen with wax emulsion of timber and preparation method thereof, the wood cutting after this wax emulsion is handled is easy and the cutting face is smooth, clean and tidy.
The percentage of being mentioned among the present invention all is weight percentage.
The present invention proposes is used to handle pen and is made up of mineral wax, stabilizing agent, auxiliary agent, emulsifying agent, anticorrisive agent and water with the wax emulsion of timber, and its prescription is as follows:
Mineral wax 15~30%
Stabilizing agent 4~8%
Auxiliary agent 4~8%
Emulsifying agent 4~8%
Anticorrisive agent 1~2%
Water 44~72%.
The present invention proposes, and to be used to handle pen as follows with the wax emulsion optimization formula of timber:
Mineral wax 18~28%
Stabilizing agent 5~7%
Auxiliary agent 5~7%
Emulsifying agent 4~7%
Anticorrisive agent 1~2%
Water 49~66%.
Described mineral wax is 52~No. 60 a semi-refined paraffin wax, montan wax, or their mixture.
Described auxiliary agent be contain hydroxyl or contain hydroxyl and amino polyacid in one or more, wherein contain hydroxyl or contain hydroxyl and the amino preferred C of polyacid
2~C
6Contain hydroxyl or contain hydroxyl and amino polyacid, be preferably in hydroxyethylethylene diamine tri-acetic acid, bicine N-and the oxalic acid one or more.
Described stabilizing agent is: saturated or unrighted acid, and turpentine oil, or their mixture, saturated or unrighted acid is preferably C
10~C
18Saturated or unrighted acid is preferably oleic acid and/or stearic acid.
Said emulsifying agent is selected from the non-ionic surface active agent sorbitan monooleate, or polyoxyethylene (20) sorbitan monostearate, or polyoxyethylene (20) anhydrous sorbitol tristearate, or AEO, or two or more the mixture in them.
Described AEO is preferably C
6~C
24AEO.
Said anticorrisive agent is borax, Sodium Benzoate, or their mixture.
The preparation method of wax emulsion of the present invention is as follows: take by weighing mineral wax, stabilizing agent, auxiliary agent, emulsifying agent and anticorrisive agent according to prescription and join in the reactor, slowly be heated to 105~115 ℃, mix reaction 5~15 minutes, the hot water mixing dispersion and emulsion that under high-speed stirred, adds 80~95 ℃ then, constant 15~25 minutes, handling through homogenizer, promptly is wax emulsion of the present invention again.
The using method of wax emulsion of the present invention is as follows: above-mentioned wax emulsion is placed a container, put into plank to be dyed, behind the good seal, be heated to 50~60 ℃, be pressurized to 0.010~0.015MPa again, constant temperature and pressure 50~70 minutes, take out then, baking promptly can be used for next procedure.
The preferred version of the using method of wax emulsion of the present invention is as follows: the pigment (the pH value is generally 4~7) of wax emulsion and soda acid Performance Match is mixed put into sealable container, put into pending plank then, behind the good seal, be heated to 50~60 ℃, be pressurized to 0.010~0.015MPa again, constant temperature and pressure 50~70 minutes takes out then, baking promptly can be used for next procedure.This method unites two into one plank waxdip in traditional dry method method for baking wooden board and dyeing two procedures, and the minimizing process is enhanced productivity.
Of the present invention to be used to handle pen extremely tiny evenly with the wax emulsion particle of timber, has good stability.Used Wax, auxiliary agent, stabilizing agent and emulsifying agent can both penetrate in the wood tissue space well, make a plate closely knit, and it is extremely easy to cut, and the cutting face is smooth, clean and tidy.Compare with the dry method baking plate impregnate wax method, the present invention has reduced the consumption of Wax, has also reduced the environmental pollution that is caused by dry method baking waxdip.
