Preparation method of methanal-free, mildew-free and incombustible bamboo shaving board

Abstract

The invention relates to a preparation method of a methanal-free, mildew-free and incombustible bamboo shaving board, and belongs to the field of bamboo based panels. The preparation method of the methanal-free, mildew-free and incombustible bamboo shaving board comprises the following steps that (1) primary screening of bamboo processing residues is carried out; (2) stratified screening of bambooshavings is carried out; (3) the bamboo shavings are classified and dried; (4) the bamboo shavings are classified for mildew proof treatment; (5) the mildew-proof bamboo shavings are classified and dried; (6) methanal-free and incombustible cementing materials are applied to the mildew-proof bamboo shavings in a classified manner; (7) pavement of the bamboo shavings with glue is carried out; (8)prepressing of a plate blank is carried out; (9) hot pressing of the plate blank is carried out; and (10) post-treatment is carried out. The bamboo shaving board does not contain methanal, and is notprone to mildew; and the bamboo shaving board has the characteristic of being not prone to being burned at the same time, the value of mold infection can reach zero, and the combustion performance level can reach the incombustible level A2.

Description

technical field [0001] The invention belongs to the field of bamboo wood-based panels, and in particular relates to a method for preparing bamboo particle boards without aldehyde, mildew and non-combustibility. 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. However, due to the inherent small diameter, thin wall, and hollowness of bamboo, the utilization rate of bamboo processing is often lower than 50%, resulting in most of the bamboo becoming bamboo shavings, bamboo chips and other processing residues, of which bamboo shavings account for more than 80%. %. At present, except for a small amount of bamboo processing residues used as fuel for boilers and a few small and medium-sized enterprises to make bamboo particle boards, most of them are discarded and not utilized. This not only wastes bamboo resources, but also pollutes...
