Description

A method of reducing wood color difference before and after highland hook leaf rattan thermal softening
Technical field
The invention belongs to windmill palm vine material technical field of hot working, and in particular to a kind of reduction highland hook leaf rattan thermal softening front and back The method of wood color difference.
Background technique
Rattan rattan is that " rattan " is commonly called as on commodity, and density is medium, and light firm, polishing degree height, durability are strong, and It is beautiful plain, it is the excellent material of furniture and craftwork, is widely used in manufacturing the rattans men such as table, chair, tea table, sofa, bed Tool and craftwork, the theory that naturally light-duty primary colors rattan furniture embodies modern's back to nature, pursues healthy living, are known as work The title of skill artistic products is that conventional outlet is earned foreign exchange one of commodity, has very high economic value, wherein whose evaluation rattan material table of wood color One of face characteristic and the Chinese medicine index of utility value, in thermal softening and drying process, wood color variation, chromatic value variation, Oxidation occurs with chromophoric groups certain in rattan material and auxochrome group or extract volatilization is related, it is existing the study found that wherein highly Hook leaf rattan heated by microwave, which softens lightness, reduces by 40%, and decatize thermal softening reduces by 45%, and microwave heating softens overall color difference knots modification It is 24.29, decatize thermal softening totality color difference knots modification is 28.45, the increase of lightness casting, material in the drying process of highland hook leaf rattan Gradually variable is dried the influence to rattan material Surface lightness and is less than sofening treatment, that is, after drying color compared to softening process Rattan material lightness is respectively less than untreated rattan material, same dried medium, at a temperature of, complete dry rattan wood color under higher temperature conditions Difference is greater than the value of chromatism after the completion of drying under cryogenic, and microwave drying can be reduced wood color difference, but how further decrease Color difference is not studied also now.
Summary of the invention
The purpose of the present invention is being directed to existing problem, it is poor to provide a kind of reduction highland hook leaf rattan thermal softening front and back wood color Different method.
The present invention is achieved by the following technical solutions：A kind of reduction highland hook leaf rattan thermal softening front and back wood color difference Method, including the following contents：
（1）No disease and pests harm, highland hook leaf rattan uniform in material are acquired, after cleaned, truncation under conditions of temperature is 55-60 DEG C Drying to moisture content is 12%, is then impregnated 6-10 days in soak；
Every liter of soak includes the raw material of following weight：Groomwell root oil 22-28mg, carboxymethyl chitosan 6-10mg, sulfopropyl Glycine betaine 1-2mg, isooctyl mercaptopropionate 0.6-0.8mg, surplus are water；
（2）Treated highland hook leaf rattan is heated and softened 20-30 minutes under conditions of temperature is 115 DEG C, is then existed Under conditions of 400W power microwave heating 100-120 seconds to get.
As further improvement of these options, the preparation method of the Groomwell root oil is to dry after cleaning Asian puccoon to containing Water is lower than 5%, then impregnates 12-16 hours in the wild tea oil for being equivalent to 2 times of its weight, and filtering, gained filter residue is with being equivalent to The wild tea oil of 1.5 times of its weight impregnates 2-4 hours, and then thermal extraction 20 minutes, stand diacolation 12 hours after cooling, filter, and closes And twice filtrate to get.
As further improvement of these options, the temperature of the soak is 55-65 DEG C.
As further improvement of these options, water is magnetized water in the soak, by magnetizer A400p magnetization Reason, water yield 40m3/h.
As further improvement of these options, the deacetylation of the raw materials of chitosan of carboxymethyl chitosan is 87%, carboxylic The viscosity average molecular weigh of methyl chitosan is 3.15 × 105-3.31×105。
As further improvement of these options, carboxymethyl chitosan is N- carboxymethyl chitosan or N, O- carboxymethyl shell One of glycan.
As further improvement of these options, the step（2）The Deflection Modulus of Elasticity of highland hook leaf rattan after the completion For step（1）Deflection Modulus of Elasticity 18-22%, illustrates to have reached preferable bating effect before impregnating in soak.
The present invention has the following advantages that compared with prior art：In the present invention by with soak to highland hook leaf rattan at Reason, can with inside the hook leaf rattan material of highland color development and auxochrome group be combined, rationally control thermal softening condition, reduce highland hook Color development and auxochrome group aoxidize under the high temperature conditions inside leaf rattan material, while reducing the volatilization or hydrolysis dissolution of extract, in turn The variation of lightness during reduction thermal softening, reduces the change of overall color difference.
