Problems solved by technology

[0002] At present, there are very few decorative substrates using bamboo as raw material. Due to the rapid growth of bamboo in the later period and the large output, there are not many levels of deep processing at present, mainly in the field of tables and chairs. Due to the physiological characteristics of bamboo, it is impossible to whole In use, the broken bamboo is usually bonded with glue to prepare ecological boards. Although it is widely used, it has poor antibacterial properties and is easy to crack.

[0017] S1, pulverizing the bamboo and drying until a prefabricated material is obtained;

[0018] S2. Add cellulose gel to the prefabricated material, then add polyethylene glycol and water to mix evenly, heat up, keep warm, cool down, then add titanium dioxide, disproportionated rosin, polyurethane binder, mix evenly, put it into the mold for pre-pressing , molding, and natural air-drying to obtain an antibacterial ecological composite board.

Embodiment 2

[0020] A preparation method for an antibacterial ecological composite board, comprising the steps of:

[0021] S1, pulverizing the bamboo, drying to a moisture content of 3wt%, to obtain a prefabricated material;

[0022] S2. Add 30 parts of cellulose gel to 80 parts of prefabricated materials in parts by weight, then add 160 parts of polyethylene glycol and 40 parts of water and mix evenly, heat up to 135°C, keep warm for 3 hours, cool, then add 12 parts of titanium dioxide, 4 parts of disproportionated rosin and 35 parts of polyurethane adhesive are mixed evenly, put into a mold, paved and pre-pressed, shaped, and naturally air-dried to obtain an antibacterial ecological composite board.

Embodiment 3

[0024] A preparation method for an antibacterial ecological composite board, comprising the steps of:

[0025] S1, pulverizing the bamboo, drying to a moisture content of 5wt%, to obtain a prefabricated material;

[0026] S2. Add 20 parts of cellulose gel to 90 parts of prefabricated materials in parts by weight, then add 120 parts of polyethylene glycol and 80 parts of water and mix evenly, heat up to 125 ° C, keep warm for 5 hours, cool, and then add 6 parts of titanium dioxide, 8 parts of disproportionated rosin and 25 parts of polyurethane adhesive are mixed evenly, put into a mold, paved and pre-pressed, shaped, and naturally air-dried to obtain an antibacterial ecological composite board.

[0027] The cellulose gel is prepared by the following process: uniformly mix beef extract, corncob powder, glucose, and water, inoculate Gluconacetobacter xylinum, culture dynamically on a shaker, filter, and wash to obtain the cellulose gel.

Abstract

The invention discloses a method for preparing an antibacterial ecological composite board. The method comprises the following steps: grinding bamboo wood, and drying so as to obtain a prefabricated material; adding cellulose gel into the prefabricated material, adding polyethylene glycol and water for uniform mixing, raising the temperature, maintaining the temperature, and cooling; adding titanium dioxide, disproportionated rosin and a polyurethane adhesive for uniform mixing, paving and pre-pressing in a mold, molding, and naturally airing, so as to obtain the antibacterial ecological composite board. The cellulose gel is prepared by the following process steps: uniformly mixing beef extract, corncob powder, glucose and water, inoculating gluconacetobacter xylinus, performing dynamic culture in a shake table, filtering, and washing, so as to obtain the cellulose gel. The prepared antibacterial ecological composite board is excellent in antibacterial property, high in product density and difficult to crack.

Description

technical field [0001] The invention relates to the technical field of ecological composite boards, in particular to a preparation method of an antibacterial ecological composite board. Background technique [0002] At present, there are few decorative substrates using bamboo as raw material. Due to the rapid growth of bamboo in the later period and the large output, there are not many levels of deep processing at present, mainly in the field of tables and chairs. Due to the physiological characteristics of bamboo, it is impossible to complete the whole In use, the broken bamboo is usually bonded with glue to prepare ecological boards. Although it is widely used, it has poor antibacterial properties and is easy to crack. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a method for preparing an antibacterial ecological composite board. The obtained ecological composite board has good antibacteri...
