Abstract

The invention discloses a method for performing mouldproof and mothproof treatment to bamboo. The method includes the steps of firstly, soaking the bamboo in acid solution at 20-60 DEG C for 7-9 days, and taking out the bamboo to obtain acid-soaked bamboo; secondly, carbonizing the acid-soaked bamboo in superheated steam of 110-130 DEG C for 1-3 hours to obtain carbonized bamboo; and thirdly, using desiccation to lower water content of the carbonized bamboo to 6-12 to obtain the mouldproof and mothproof bamboo. The method is simple in process, fine in controllability, low in cost, easy to industrialize, and needs no expensive equipment.

Description

A kind of processing method of bamboo wood mildew and insect proof

Technical field

What the present invention relates to is a kind of processing method of bamboo wood mildew and insect proof.

Background technology

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

But no matter bamboo wood still is furniture, artwork as construction material; All exist three natural defectives: be prone to infested mildew, cracking, distortion; In course of industrialization, have the environmental problem same again: abuse coating, adhesive, anticorrisive agent with timber industry; Processing waste is many, and artificial like this cost increase causes that inter-industry competition property is poor, market is imperfect, so that bamboo industry can not really become the industry of complete sustainable development.

To the merits and demerits more than the bamboo industry, from the angle of sustainable development, design bamboo wood mildew and insect proof treatment process through long term studies and experiment, obtains a kind of processing method of bamboo wood mildew and insect proof.

Summary of the invention

Technical problem to be solved by this invention is to be to provide a kind of technology simple, and controllability is good, and cost is low, does not need expensive equipment, is easy to the processing method of the bamboo wood mildew and insect proof of industrialization.

In order to solve the problems of the technologies described above, the processing method of bamboo wood mildew and insect proof provided by the invention, procedure of processing comprises:

(1), bamboo wood is immersed in the acid solution, soaking technology is volume ratio=1 of 20-60 ℃ of temperature, bamboo wood and acid solution: (0.5-2.0), 7-9 days, take out bamboo wood then, obtain acid bubble bamboo; Wherein acid solution be by formic acid, acetic anhydride, maleic anhydride, folium eucalypti acid according to mass percent concentration (0.1-0.2%): (0.2-0.4%): (0.1-0.15%): (0.3-0.5%) mix.

(2), bamboo steeped in acid in 110-130 ℃ of water vapour, carried out charing 1-3 hour, medium is a superheated vapour, promptly gets the charing bamboo.

(3), then adopt seasoning that charing bamboo moisture content is dropped to 6-12, promptly get the mildew and insect proof bamboo wood; As long as wherein seasoning is meant that all drying means that can make the bamboo moisture content drop to 6-12 all can.

Adopt the processing method of the bamboo wood mildew and insect proof of technique scheme, the mildew and insect proof bamboo wood of processing, mechanical strength descends in 9%, has effects such as mildew-resistant, insect protected.Technology 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 provides a kind of technology, and controllability is good, and cost is low, do not need expensive equipment, is easy to the processing method of the bamboo wood mildew and insect proof of industrialization.
