Abstract

The invention relates to a preparation method of a formaldehyde-free non-mildew non-combustible bamboo fiber board, and belongs to the field of bamboo-wood artificial boards. The preparation method ofthe formaldehyde-free non-mildew non-combustible bamboo fiber board comprises the following steps that (1), the bamboo sections are prepared; (2), a bamboo section longitudinal section, a tabasheer and an inner section are prepared; (3), bamboo blocks are subjected to shaving; (4), bamboo chips are used for preparing bamboo fibers; (5), the bamboo fibers are subjected to mildew-proof treatment; (6), the mildew-proof bamboo fiber is dried; (7), a formaldehyde-free non-combustible cementing material is applied to the mildew-proof bamboo fiber; (8), a glue applying bamboo fiber paving is carriedout; (9), a plate blank is pre-pressed; (10), hot pressing is performed on the plate blank; and (11), post-treatment is carried out. The prepared bamboo fiber board does not contain formaldehyde, isnot easy to mildew, and meanwhile has the characteristic of difficult combustion; and the mold infection value can reach zero, 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 preparation method of a non-aldehyde, mildew-free and non-combustible bamboo fiber board. Background technique [0002] China's bamboo processing technology and level are in the leading position in the world, and bamboo wood-based panels are the main product and core of bamboo processing. Among them, bamboo fiberboard has been widely used in construction, furniture and other industries due to its uniform structure and excellent processing performance. However, formaldehyde-based adhesives are basically used in the manufacture of bamboo fiberboards. The harmful substance formaldehyde will be released during the production and use of bamboo fiberboards, which will cause great harm to the health of employees and consumers. It is urgent to develop formaldehyde-free bamboo fiberboards. In addition, the nutrients necessary for mold such as sugar, starch, and prote...
