Detailed description of the invention
See Fig. 1-Fig. 4, the processing method of a kind of fire protection flame retarding bamboo of the present invention wood, is characterized in that, comprise the following steps:
1, first raw material are processed into filament, size after processing meets the size of curtain processing, the dimensions length of such as bamboo chip is 160,190,260 or 320mm, generous is 6mm × 1.2mm, 7mm × 1.8mm, 12mm × 1.8mm, the length of bamboo silk is 130mm, 160mm, 190mm, 260mm, 320mm, bamboo filament diameter is 2.5,1.8 or 1.2mm, and wooden louvres sheet width 2.5-5mm.These sizes are determined according to the size of curtain, generally according to thickness and the width of curtain, considers that the width of bamboo is to form various striped simultaneously; These materials also can be timber, grass (rope) or fiber crops material.
2, bleaching (material very white for quality or need to retain the material of primary colors also can save this step, see Fig. 1 and Fig. 3); Bleaching is carried out to the material after above-mentioned processing, bleaching is to be processed into by bamboo wood material not containing the material of natural pigments, simultaneously by bleaching the sugared part can removed former bamboo and produce in growth course, or remove the foreign material being attached to bamboo material surface, keep bamboo wood material consistency of colour and clean.
Bleaching agent uses hydrogen peroxide, and the time standby temperature of bleaching is the water of 60-95 DEG C, and the time of bleaching will be kept to be 50-90min simultaneously.Hydrogen peroxide is used to make bleaching, play the effect of oxidation bleaching, simultaneously still a kind of preservative treatment, prevent final products because the reason of former bamboo itself is easily mouldy, keeping the clean of curtain, using when bleaching the water with uniform temperature to be sugared part in order to remove former bamboo inside.The concentration of the hydrogen peroxide used during bleaching controls at 12-20mol/l.It is suitable that the concentration of hydrogen peroxide will control, and concentration is too high, and easily by the fiber destruction of former bamboo inside, the too low effect can not playing again bleaching oxidation of concentration, the concentration of hydrogen peroxide also can change according to the age difference of former bamboo to some extent.

During flame treatment, raised pressure is to 2-4.5MPa gradually, and the time controling of boosting is at 35-45min, and the time controling of pressurize is at 50-79min, and the time controling of last step-down is at 10-15min.The pressure of pressurize, time determine according to the size of bamboo chip or bamboo silk, and the surface area of bamboo chip is larger, the pressure of use can higher while pressurize time also can proper extension.
The process of 1-3 boosting-pressurize-step-down is carried out in flame treatment.Repeatedly repeat this process, be the thickness of the permeable formation in order to deepen fire retardant as far as possible, or form a kind of stacked flame-retardant layer structure on the surface of bamboo wood material.
It is phosphorus-nitrogen (Phospphorus-nitrogen) compound that fire retardant adopts from a kind of chemical name of Japanese import, and trade name is NON-NEN 984.Another kind of chemical name is Sulfer-halogen compound, and trade name is NON-NEN R028-8.Manufacturer is MARUBISHI OIL CHEMICAL CO.LTD(manufacturer address: 2-11 RINKAI-CHO IZUMIOTSU-SHI OSAKA JAPAN).
5, second time drying method is dry identical with first time.
6, fire-retardant experiment is carried out:
Dried material carries out fire retardancy test, and described fire-retardant experimental procedure is: the material after process is made curtain, and be 45o angle with flame, and keep 5cm with flame, burning time is 120s, and the diameter in the region of bamboo wood burning or turning white is not more than 50mm.This is the mode of experiment and the data of requirement of experiment, and reaching these objects is exactly qualified products.If do not meet the requirements of data, need to re-start fire retardant infiltration process.
