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.

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...
