Abstract

The invention discloses a mildew-proof and mothproof treatment method for bamboo materials. The method comprises the following processing steps of: (1) immersing the bamboo materials in a solution according to the volume ratio that the bamboo materials to the solution is (0.3-1):(1-3) at 10-50 DEG C for 3-5d, and taking out the bamboo materials to obtain immersed bamboos; and (2) subjecting the immersed bamboos to a smoking treatment in smoke of 60-90 DEG C for 5-9d to obtain the mildew-proof and mothproof smoked bamboos, wherein the medium is boiler smoke. The invention provides the mildew-proof and mothproof treatment method for bamboo materials, which is simple in process, high in controllability, low in cost, free of expensive apparatus and easy for realizing industrialization.

Description

A kind of bamboo wood anti-mould and anti-moth processing method

Technical field

What the present invention relates to is a kind of method prepared by anti-mould and anti-moth bamboo processing.

Background technology

The Chinese government is for alleviating timber imbalance between supply and demand, the realization " wood substituted by bamboo " being becoming tight day, plan in 15 years 1200000 hectares of transformations and newly-built bamboo base, and sets up the bamboo class that an individual system is complete and research and develop network, to promote Bamboo Industry.Approximately 1,064 ten thousand mu of the existing bamboo grove areas of Jiangxi Province, 2005, always accumulate 10.4 hundred million strain mao bamboons, in Jiangxi Province's government planning the Eleventh Five-Year Plan period, proposition is under the prerequisite of preserving the ecological environment, fully develop mountain region resource, greatly develop forestry industry, tentatively build up standardized and orderly, intensive farming, rational in infrastructure, dynamic forestry industry system, the change large province of forest resourceies is the large province of forestry industry, for Jiangxi increases green and wealth, by 2010, the whole province's forestry industry gross output value is striven over 80,000,000,000 yuan, than 2005, double, the first five is strong to enter national forestry industry, the annual income that peasant obtains per capita from forestry is over 800 yuan.Wherein take mao bamboon as main bamboo industry, 20Ge county greatly develops in 100Ge small towns Bamboo woods base, cultivates 50 annual sales amounts and reaches the leading enterprise of 5,000 ten thousand yuan, by 2010, build 9,000,000 mu, use material and bamboo shoot bamboo dual-purpose high yield bamboo grove, realize 10,000,000,000 yuan of mao bamboon industry annual value of production.But, by calculating approximately 25 yuans of every strain output values the period of felling in turn of 5 years, be nonetheless, mainly former bamboo and rough machined income thereof.

Bamboo has that growth is fast, output high, and once after afforestation as long as manage rationally, can continuous utilization; The purposes of bamboo is very extensive, except being processed into food, handicraft, more can be used for the every field such as building, material, chemical industry.As construction timber, every 60 bamboos just can replace a balk.Bamboo product (especially bamboo craftwork product) is more and more subject to people and likes in daily life, and bamboo furniture also comes into vogue gradually.

But no matter bamboo wood is as construction material or furniture, artwork, all exist three natural defects: easy infested mildew, cracking, distortion, in course of industrialization, there is again the environmental problem same with timber industry: abuse coating, adhesive, anticorrisive agent, processing waste is many, artificial like this cost increase causes that inter-industry competition is poor, market is imperfect, so that bamboo industry can not really become the industry of complete sustainable development.

For merits and demerits more than bamboo industry, structure and function from the angle re-examine bamboo industry of industry design principle, according to " basic technology---application technology---core technology---technology group's---core industry---industrial colony " technology---industry development chain rule, through long-term research and experiment, processing method > > (China an invention < < black bamboo, publication number: CN101234499, time of disclosure: on 08 06th, 2008) on basis, obtain again the novel processing method of a kind of bamboo wood.

Summary of the invention

Technical problem to be solved by this invention is to be to provide a kind of technique simple, and controllability is good, and cost is low, does not need expensive equipment, is easy to the bamboo wood anti-mould and anti-moth processing method of industrialization.

In order to solve the problems of the technologies described above, bamboo wood anti-mould and anti-moth processing method provided by the invention, procedure of processing comprises:

(1), bamboo wood is immersed in solution, soaking technology is volume ratio=(0.3～1) of 10～50 ℃ of temperature, bamboo wood and solution: (1～3), soak 3～5 days, then take out bamboo wood, obtain soaking bamboo; Wherein the solute of solution is according to mass ratio m by phenylalanine, histidine, proline _{phenylalanine}: m _histidine: m _proline=(1%～3%): (2%～5%): (5%～9%), solution concentration is 50g～200g/m ³;

(2), immersion bamboo is carried out to sootiness 5～9 days in 60 ℃～90 ℃ flue gases, medium is boiler smoke, obtains anti-mould and anti-moth sootiness bamboo.

The bamboo wood anti-mould and anti-moth processing method that adopts technique scheme, the sootiness bamboo of processing, presents black, grey or black gray expandable, mechanical strength declines in 10%, has the faint scent of bamboo, mildew-resistant, look was not returned in insect protected in 10 years, and without any side effects.Technique of the present invention is simple, and controllability is good, and cost is low, does not also need expensive equipment, is easy to industrialization, and prospect is widely used.

In sum, it is simple that the present invention is to provide a kind of technique, and controllability is good, and cost is low, do not need expensive equipment, is easy to the bamboo wood anti-mould and anti-moth processing method of industrialization.
