Description

A kind of high stability dyeing treatment of timber
Technical field
The invention belongs to wicker plaiting article working process technical fields, and in particular to a kind of high stability dyeing processing side of timber Method.
Background technique
Funan County is under the jurisdiction of Anhui Province's Fuyang City, belongs to inland exploitation area earlier, on the Anhui Province northwestward, Huaihe River Middle reaches engaging portion north bank.Funan County is known as the title in " famous-brand and high-quality specialty county ", " Natural resources reservoir ", be national grain-production great Xian, in Unique agriculture (forestry) the circular economy demonstration pilot project county in township, the whole nation of state's wicker plaiting article, Funan is the township of national wicker plaiting article, wicker products It is sold abroad.
Timber is one of common raw material of wicker products, and timber self color is single, needs to carry out dyeing processing more, with Promote ornamental value, practicability and value.It is relatively simple for the dyeing processing mode of timber at present, cause coloring effect bad, The quality used and service life are affected, needs further to improve.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of high stability dyeing treatment of timber is provided.
The present invention is achieved by the following technical solutions:
A kind of high stability dyeing treatment of timber, includes the following steps:

(2) radiation treatment:
By step (1), treated, and timber is put into irradiation box, is used60Co- gamma-rays to timber carry out radiation treatment, 1 ~ It is taken out after 1.2h spare；
(3) modification liquid sprays processing:
It is 80 ~ 85 that pre-prepared modification liquid, which is sprayed on step (2) treated wood surface, being then placed in temperature, DEG C drying box in be dried 2 ~ 3h after take out it is spare；
(4) dyeing is handled:
By step (3), treated, and timber is immersed in coloring agent, while being ultrasonically treated, and is taken out timber after 1 ~ 2h, most After be dried to water content be 10 ~ 15% after.
Further, described in step (2)60Co- gamma-ray irradiation processing when control irradiation accumulated dose be 1500 ~ 1800Gy。
Further, the preparation method of modification liquid described in step (3) includes the following steps:
1) imidazole type ion liquid and dehydrated alcohol are first added into reaction kettle, and the temperature in reaction kettle is risen to 50 ~ 55 DEG C, After being stirred continuously 28 ~ 32min of processing, p-chloromethyl styrene, triiodide boron, azodiisobutyronitrile and nanometer nitrogen are sequentially added Change titanium, then the temperature in reaction kettle is risen to 80 ~ 85 DEG C, insulation reaction handles 20 ~ 22h, takes out obtain pale yellow colored solid after the completion Body material A is spare；
2) into reaction kettle be added the resulting material A of step 1), then add 1,2- dichloroethanes, be stirred continuously processing 1.3 ~ After 1.6h, then anhydrous ferric trichloride, cyclodextrin and chitosan are added into reaction kettle, then the temperature in reaction kettle is heated and is kept It is 52 ~ 55 DEG C, insulation reaction handles 15 ~ 18h, and it is spare to obtain tan product material B for taking-up after the completion；
3) the resulting material B of step 2 is added into reaction kettle, then adds dehydrated alcohol, hexafluorophosphoric acid aqueous solutions of potassium, then Temperature heating in reaction kettle is remained 32 ~ 36 DEG C, insulation reaction handles 17 ~ 19h, is filtered under diminished pressure, successively spends after the completion After ionized water, methanol and acetone washing one time, then through methanol extracting 22 ~ for 24 hours, it is finally putting into vacuum oven and is dried It is taken out after 12 ~ 16h.
Further, imidazole type ion liquid described in step 1) is 1-(4- vinyl benzyl) -3- butyl imidazole six The mass volume ratio that fluorophosphate, the imidazole type ion liquid and dehydrated alcohol are added is 1g:18 ~ 20ml, described to chloromethane Base styrene, triiodide boron, azodiisobutyronitrile and Nano titanium nitride additional amount be successively imidazole type ion liquid gross mass 340 ~ 360%, 20 ~ 24%, 18 ~ 22% and 18 ~ 22%, be always nitrogen protection environment in the reaction kettle.
Further, material A described in step 2 and 1,2- dichloroethanes be added mass volume ratio be 1g:36 ~ 39ml, the additional amount of the anhydrous ferric trichloride, cyclodextrin and chitosan is successively the 115 ~ 125% of material A gross mass, 13 ~ 16% and 17 ~ 20%, it is always nitrogen protection environment in the reaction kettle.
