Problems solved by technology

[0003] However, whether bamboo is used as a building material or a furniture or handicraft material, there are three natural defects: easy to grow insects, mold, cracks, and deformation. In the process of industrialization, it has the same environmental problems as the wood industry: abuse of paint, adhesives, There are many preservatives and processing waste. Such artificial cost increases lead to poor industry competitiveness and incomplete market, so that the bamboo industry cannot truly become a complete and sustainable industry.

Embodiment 1

[0014] A treatment method for preventing mildew and insects of bamboo, the processing steps comprising:

[0015] (1), bamboo is soaked in acid solution, soaking process is 20 ℃ of temperature, the volume ratio of bamboo and acid solution=1: 2.0, 9 days, then takes out bamboo, obtains acid bubble bamboo; Wherein acid solution is made of formic acid, Acetic anhydride, maleic anhydride, and eucalyptol are mixed according to the mass percentage concentration of 0.1%: 0.2%: 0.1%: 0.3%;

[0016] (2), carbonize the sour soaked bamboo in 110°C water vapor for 3 hours, the medium is superheated steam to obtain carbonized bamboo;

[0017] (3), then adopt the drying method to reduce the moisture content of the carbonized bamboo to 12, and obtain the mildew-proof and insect-proof bamboo material; wherein the drying method refers to all drying methods as long as the moisture content of the bamboo can be reduced to 12.

Embodiment 2

[0019] A treatment method for preventing mildew and insects of bamboo, the processing steps comprising:

[0020] (1), bamboo is soaked in acid solution, soaking process is 30 ℃ of temperature, the volume ratio of bamboo and acid solution=1: 1.5, 9 days, then takes out bamboo, obtains acid bubble bamboo; Wherein acid solution is made of formic acid, Acetic anhydride, maleic anhydride, and eucalyptol are mixed according to the mass percentage concentration of 0.1%: 0.4%: 0.1%: 0.3%;

[0021] (2), carbonize the pickled bamboo in 115°C water vapor for 3 hours, the medium is superheated steam to obtain carbonized bamboo;

[0022] (3), then adopt the drying method to reduce the moisture content of the carbonized bamboo to 10, and obtain the mildew-proof and insect-proof bamboo material; wherein the drying method refers to all drying methods as long as the moisture content of the bamboo can be reduced to 10.

Embodiment 3

[0024] A treatment method for preventing mildew and insects of bamboo, the processing steps comprising:

[0025] (1), bamboo is soaked in acid solution, soaking process is 40 ℃ of temperature, the volume ratio of bamboo and acid solution=1: 1.0, 8 days, then takes out bamboo, obtains acid foam bamboo; Wherein acid solution is made of formic acid, Acetic anhydride, maleic anhydride, and eucalyptol are mixed according to mass percentage concentration (0.2%: 0.2%): 0.15%: 0.5%;

[0026] (2), carry out carbonization in 120 ℃ steam of pickled bamboo for 2 hours, medium is superheated steam, obtains carbonized bamboo;

[0027] (3), then adopt the drying method to reduce the moisture content of the carbonized bamboo to 10, and obtain the mildew-proof and insect-proof bamboo material; wherein the drying method refers to all drying methods as long as the moisture content of the bamboo can be reduced to 10.

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

technical field [0001] The invention relates to a treatment method for preventing mildew and insects of bamboo. Background technique [0002] Bamboo has the characteristics of fast growth and high yield, and it can be used continuously as long as the management is reasonable after a forestation. Bamboo has a wide range of uses. In addition to being processed into food and handicrafts, it can also be used in various fields such as construction, materials, and chemicals. As a building material, every 60 pieces of bamboo can replace one side of wood. Bamboo products (especially bamboo handicrafts) are becoming more and more popular in daily life, and bamboo furniture is gradually becoming popular. [0003] However, whether bamboo is used as a building material or a furniture or handicraft material, there are three natural defects: easy to grow insects, mold, cracks, and deformation. In the process of industrialization, it has the same environmental problems as the wood industr...
