Description
Technical field
The invention belongs to wood technologies exploitation and technical field of modification, and in particular to a kind of system of the transparent timber of higher curvature
It is standby.
Background technique
Theoretically, if removing lignin, pigment, tannin and resin etc. in timber by physically and/or chemically method has
Color substance, then the consistent substance of refractive index is uniformly filled in wood, so that light is not occurred when passing through timber or is rolled over less
It penetrates, reflect and scatters, can achieve the purpose that transparent.And timber then needs to remove as far as possible to obtain high light transmittance
Lignin.But delignification rate is higher, and timber then easily disperses, if further to carry out the bending of higher curvature to timber, then more
It is difficult.Currently, scholar few in number studies transparent timber, but do not occur curved face type also in all research
Transparent timber realizes flexibility design to transparent timber.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the object of the present invention is to provide a kind of systems of the transparent timber of higher curvature
It is standby, and the transparent timber mechanical performance of made curved surface is excellent, light transmittance has high market application value up to 85% or more.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of preparation of the transparent timber of higher curvature, comprising the following steps:
1) first sample is immersed in aqueous slkali and carries out swollen；
2) Microwave Pretreatment 1-5min after taking out the sample after swollen;
3) sample handles 1-4h with sodium chlorite solution in acid condition after again handling step 2, obtains complete de- wood
Plain timber substrate sample, delignification rate are up to 95%；
4) complete delignification timber substrate sample is subjected to organic solvent serial dehydration, obtains anhydrous delignification timber substrate
Sample；
5) anhydrous delignification timber substrate sample is impregnated into optics light-transmission type polymer similar in refractive index and fiber,
Optics light-transmission type monomer-polymer is loaded under room temperature using vacuum-impregnated method the cell of above-mentioned curved timber substrate
On intracavitary and cell wall and in other intercellular ducts, when vacuum impregnation a length of 2-10h, the final wood for obtaining flexible high light transmission
Material；
7) wood plank for obtaining flexible high light transmission is put into homemade flexible bending mold, carries out bending plastotype, obtain curved surface
High light transmission timber；
8) by the timber of the high light transmission of curved surface at 50-75 DEG C precuring 1-2h, then heat to 80-105 DEG C of solidification 2h, finally
Obtain a kind of transparent timber of higher curvature.
Aqueous slkali in the step 1) is 2%-10% sodium hydroxide solution.
The concentration of sodium chlorite solution in the step 3) is 1%-10%.
Organic solvent serial dehydration in the step 4) use various concentration gradient (40%, 60%, 80%, 90%,
100%) alcohol, alcohol: acetone 1:1 solution and 100% acetone successively displace the moisture in sample.
Optics light-transmission type polymer similar in refractive index and fiber in the step 5) be polymethyl methacrylate,
It is any one in polystyrene, gaultherolin, methyl cinnamate, methyl benzoate, ethyl-cinnamic acid ester, Ergol etc.
The optics light-transmission type polymer of kind or a variety of compoundings.
The beneficial effects of the present invention are:
1) growthform that the present invention still maintains timber natural；
2) present invention has the optics light transmittance higher than 85% or more；
3) present invention has high curved surface characteristic, and curved surface can be adjusted according to actual needs, by solidifying plastotype, is had
There is Stability Surface；
4) present invention has good mechanical characteristic, drop resistant；
5) present invention gives the novelty of timber design and application, the application field of timber has been widened, has been renewable resource
Development and utilization provide good social value.
Detailed description of the invention
The timber pictorial diagram of Fig. 1 flexibility high light transmission.
Specific embodiment
The present invention is further discussed below with reference to embodiments, but the present invention is not limited to following embodiment.
