Problems solved by technology

[0002] In the prior art, there is a hot-pressing step in the preparation process of bamboo-wood composite flooring. Because the temperature in the hot-pressing process is higher, the bamboo slab itself has mildew resistance. Anti-moth effect, therefore, there is no special anti-mildew and anti-moth step in the prior art, however, because the hot pressing process time is short, generally 10-20min, therefore, the anti-mildew and anti-moth effect is poor

Embodiment 1

[0011] Example 1: A bamboo chip anti-mold and moth-proof method for preparing bamboo-wood composite flooring, which sequentially includes the following steps:

[0012] (1) Put the bamboo slices in a hot water tank at 60℃ and let stand for 5 minutes;

[0013] (2) After adding 30% hydrogen peroxide and sodium lofenolate, the weight ratio of 30% hydrogen peroxide to bamboo flakes is 1:12.5, and the weight ratio of sodium lofenolate to bamboo flakes is 1:100; stir; 2min;

[0014] (3) Heat the water in the tank with steam, boil it to 100°C within 5 minutes, and keep it for 6 hours;

[0015] (4) Put the bamboo chips in step (3) in a carbonization box, and control the temperature in the carbonization box to be 150°C and humidity to 75%, and keep it for 5 hours.

Embodiment 2

[0016] Example 2: A bamboo chip anti-mold and moth-proof method for preparing bamboo-wood composite flooring, which sequentially includes the following steps:

[0017] (1) Put the bamboo slices into a 65℃ hot water tank and let stand for 7 minutes;

[0018] (2) After adding 30% hydrogen peroxide and sodium lophenolate, the weight ratio of 30% hydrogen peroxide to bamboo flakes is 1:15, and the weight ratio of sodium lophenolate to bamboo flakes is 1:150; stir; 2.5min;

[0019] (3) Heat the water in the tank with steam, boil it to 100°C within 8 minutes, and keep it for 7 hours;

[0020] (4) Put the bamboo chips in step (3) in a carbonization box, and control the temperature in the carbonization box to 160°C and humidity to 80%, and keep it for 6 hours.

Embodiment 3

[0021] Example 3: A method for preventing mildew and moth of bamboo slices in the preparation process of bamboo-wood composite flooring, which sequentially includes the following steps:

[0022] (1) Put the bamboo slices into a 70℃ hot water tank and let stand for 8 minutes;

[0023] (2) After adding 30% hydrogen peroxide and sodium lophenolate, the weight ratio of 30% hydrogen peroxide to bamboo flakes is 1:20, and the weight ratio of sodium lophenolate to bamboo flakes is 1:120; stir; 3min;

[0024] (3) Heat the water in the tank with steam, boil it to 100°C within 10 minutes, and keep it for 8 hours;

[0025] (4) Put the bamboo chips in step (3) in a carbonization box, control the temperature in the carbonization box to be 180°C and humidity to 85%, and keep it for 7 hours.

Abstract

The invention relates to a bamboo-wood composite floor manufacture process, in particular to a method for protecting bamboo chips against mold and moth in the bamboo-wood composite floor manufacture process. The invention is realized through the technical scheme that the method for protecting bamboo chips against mold and moth in the bamboo-wood composite floor manufacture process comprises the following steps: (1) bamboo chips are placed in a hot water storage tank at a temperature between 60 DEG C and 70 DEG C, and stand for 5-8 min; (2) hydrogen peroxide with 30% concentration and loxoprofen sodium are added to the hot water storage tank, the weight ratio of hydrogen peroxide with 30% concentration to the bamboo chips is 1:12.5-20, the weight ratio of loxoprofen sodium to the bamboo chips is 1:100-120, and the bamboo chips, hydrogen peroxide and loxoprofen sodium are stirred for 2-3min; and (3) steam is used to heat water in the tank to increase the temperature of the water to 100 DEG C in 5-10min, and the water is kept in boiling state for 6-8h. The method achieves excellent mold and moth prevention.

Description

technical field [0001] The invention relates to a production process of a bamboo-wood composite floor, in particular to a method for preventing mildew and moth of bamboo slices in the preparation process of a bamboo-wood composite floor. Background technique [0002] The bamboo-wood composite flooring preparation process in the prior art has a hot-pressing step. Because the temperature in the hot-pressing process is higher, the bamboo slab itself has anti-mildew and anti-mite effects. For the mildew and moth prevention step, however, due to the short heat-pressing process time, generally 10-20 minutes, the mildew and moth prevention effect is poor. Contents of the invention [0003] The object of the present invention is to provide a method for preventing mildew and moth of bamboo slices in the preparation process of bamboo-wood composite flooring. The method has a good effect of preventing mildew and moth. [0004] Above-mentioned technical purpose of the present inventi...
