Abstract
The present invention relates to a production method of varnished solid lumber, also relates to the application field of nuclear radiation technology. It is charactericed by placing dried lumber into closed container and adopting systematic treatment method including chemical impregnation, nuclear radiation irradiation and pressing, etc. so as to obtain the invented lumber with high hardness, high strength, good quality and abrasive resistance. Said invented process is simple and reliable.
Description
The present invention relates to a kind of preparation method of varnished solid wood material, also relate to the application of nuclear radiation tech.
Wood treatment method of the prior art has waxdip, is about to after the wax heating timber be immersed wherein, and wax immerses timber makes timber not yielding, and can anticorrosion protection against the tide.But the hardness of timber, wear-resisting, fire resistance do not improve.Attaching other hard material at wood surface can increase case hardness, but can not increase the intensity of timber.Along with improving constantly of people's living standard, to high-class timber as: the demand of redwood, pine etc. increases gradually, but is to use these timber, certainly will will cut down a large amount of forest reserves, bring considerable damage to environment.
The objective of the invention is to provides a kind of preparation method of varnished solid wood material at shortcoming of the prior art, gives birth to economic timber with speed, is processed into high-quality timber.
The present invention is realized that by following technology the timber that drying is good is put into closed container, vacuumizes to reach 80-140Pa, and pressurize 2-20 hour, then maceration extract is poured in the closed container, to 2-6MPa, pressurize 2-10 hour, pour out raffinate with nitrogen pressure; Put into radiation chamber again and be forced into 2-6MPa, simultaneously timber is carried out the nuclear radiation irradiation, integral dose 1-10KGy, taking-up gets final product.

The radiation source of the nuclear radiation irradiation among the present invention is cobalt 60 (Co-60) or caesium 137 (Cs-137).
Technology of the present invention is simple; adopt system handles methods such as chemical impregnation, nuclear radiation irradiation, pressurization; the low-grade change performance of general economic timber is processed into hardness height, the wear-resisting timber of high-quality that intensity is big; substitute senior timber such as redwood; can reduce felling greatly, help the conservation of nature environment forest.
The present invention will be further described below in conjunction with embodiment.
Embodiment 1:
The poplar dressed lumber that drying is good is put into the 1200ml closed container, vacuumize and reach 80-140Pa, pressurize 8 hours, then with methyl methacrylate 550ml and butyl acrylate 450ml, tricresyl phosphate (2,3-two chloropropyls) ester 100ml, propane diols 80ml, ethanol 10ml, EDTA disodium salt 1.5 gram, red smart 4 gram mixings are poured in the closed container, with nitrogen pressure to 4MPa, raffinate is poured out in pressurize 6 hours; Put into radiation chamber and be forced into 4MPa, carry out the nuclear radiation irradiation with 60 pairs of timber of cobalt, integral dose 5KGy, taking-up gets final product.
Embodiment 2:
The poplar dressed lumber that drying is good is put into the 1200ml closed container, vacuumize and reach 80-140Pa, pressurize 2 hours, then with methyl methacrylate 800ml and butyl acrylate 8ml, tricresyl phosphate (2,3-two chloropropyls) ester 140ml, propane diols 60ml, ethanol 14ml, EDTA disodium salt 1 gram, red smart 8 gram mixings are poured in the closed container, with nitrogen pressure to 2MPa, raffinate is poured out in pressurize 2 hours; Put into radiation chamber and be forced into 6MPa, carry out the nuclear radiation irradiation with 60 pairs of timber of cobalt, integral dose 1KGy, taking-up gets final product.
Embodiment 3:
The poplar dressed lumber that drying is good is put into the 1300ml closed container, vacuumize and reach 80-140Pa, pressurize 12 hours, then with methyl methacrylate 170ml and butyl acrylate 850l, tricresyl phosphate (2,3-two chloropropyls) ester 140ml, propane diols 140ml, ethanol 6ml, EDTA disodium salt 2.5 gram, red smart 2 gram mixings are poured in the closed container, with nitrogen pressure to 6MPa, raffinate is poured out in pressurize 2 hours; Put into radiation chamber and be forced into 2MPa, carry out the nuclear radiation irradiation with 137 pairs of timber of caesium, integral dose 10KGy, taking-up gets final product.
Among the present invention, red essence is a general merchandise, and main effect is painted, and its consumption can require increase and decrease according to the color and luster of finished product.Radiation source is best with the cobalt effect.The main effect of methyl methacrylate is the hardness of the product that are adjusted to.Selected timber can be poplar, the living seeds of elm constant speed, and according to selected trees difference, the adjusting process parameter is to reach optimum efficiency.The every index of treated timber all can reach the redwood standard, handles to reach the timber center deeply.
