Embodiment 1

[0061] A preparation method of a Chinese herbal medicine antifungal agent is as follows: soak the Chinese herbal medicine in 70% ethanol solution, the mass ratio of the Chinese herbal medicine to ethanol is 1:5, heat up to 50°C, filter and remove the filter residue after heating for 120min, and obtain the Chinese herbal medicine concentration of 98.2mg / ml Chinese herbal antifungal agent;

[0062] The above-mentioned Chinese herbal medicine is composed of the following components in parts by weight: 20 parts of thyme, 50 parts of male clove, 15 parts of cinnamaldehyde and 10 parts of tangerine peel.

Embodiment 2

[0064] A preparation method of a Chinese herbal medicine antifungal agent is as follows: soak the Chinese herbal medicine in 40% ethanol solution, the mass ratio of the Chinese herbal medicine to ethanol is 1:20, heat up to 80° C., filter and remove the filter residue after heating for 30 minutes, and obtain the Chinese herbal medicine concentration of 52.7mg / ml Chinese herbal antifungal agent;

[0065] The above-mentioned Chinese herbal medicine is composed of the following components in parts by weight: 30 parts of thyme, 60 parts of male clove, 10 parts of cinnamaldehyde and 5 parts of tangerine peel.

Embodiment 3

[0067] A preparation method of a nano-silver-zinc composite antifungal agent is as follows: Weigh 75 parts of zinc acetate, 15 parts of anhydrous sodium carbonate, 5 parts of silver nitrate and 10 parts of sodium dodecylbenzenesulfonate, and grind them in a mortar Mix evenly, then wash with deionized water and absolute ethanol respectively, filter and dry, and then put it into a high-temperature roasting furnace for sintering at a temperature of 250-500°C to obtain a nano-silver-zinc composite antifungal agent.

Abstract

The invention relates to a preparation method of an aldehyde-free non-mildew non-combustible recombined bamboo floor, and belongs to the field of bamboo artificial floors. The preparation method of the aldehyde-free non-mildew non-combustible recombined bamboo floor comprises the following steps that (1), bamboo sections are prepared; (2), a bamboo section longitudinal section, a tabasheer and aninner section are prepared; (3), bamboo blocks are subjected to longitudinal wire rolling; (4), cord fabric type bamboo bundle is dried; (5), mildew-proof treatment is performed on the cord fabric type bamboo bundle; (6), the mildew-proof cord fabric type bamboo bundle is dried; (7), an aldehyde-free non-combustible cementing material is applied to the mildew-proof cord fabric type bamboo bundle;(8), the glue-applied cord fabric type bamboo bundle assembly blank is prepared; (9), an aldehyde-free non-mildew non-combustible recombined bamboo rough edge plate or square material is pressed; (10), the rough edge plate or square material is subjected to thermal refining; and (11), the post-processing of the non-formaldehyde non-mildew non-combustible recombined bamboo floor is achieved. The prepared recombined bamboo floor does not contain formaldehyde and is not easy to mildew, and meanwhile has the characteristic that the combustion is not easy; and the mold infection value can reach 0,and the combustion performance grade reaches the non-combustible A2 grade.

Description

technical field [0001] The invention belongs to the field of bamboo wood-based panels, and in particular relates to a method for preparing a non-aldehyde, mildew-free and non-combustible recombined bamboo floor. Background technique [0002] As a new type of bamboo wood-based panel, recombined bamboo flooring has developed rapidly in the past ten years and has been widely used in decoration, furniture and other fields, and there is still an increasing momentum. However, the manufacture of recombined bamboo flooring basically uses phenolic resin adhesives. In addition to containing free phenol, some formaldehyde is released during the production and use of bamboo recombined bamboo flooring, which causes great harm to people's health. There is an urgent need for research and development. Aldehyde reconstituted bamboo flooring. In addition, bamboo contains a large amount of sugar, starch, protein and other nutrients necessary for mold, which makes the recombined bamboo floor e...
