Abstract

The invention relates to the field of bamboo floor processing, in particular to a preparation method for an anti-flaming bamboo floor. The preparation method for the anti-flaming bamboo floor is realized by the following technical scheme that the preparation method for the anti-flaming bamboo floor comprises the following steps: (1) cutting off and hacking an original bamboo, and sawing to obtain a green blank plate; (2) carrying out carbonized treatment, putting a bamboo chip into a high-pressure processing tank, introducing high-pressure saturated vapor into the tank, improving pressure to 0.2-0.3MPa, keeping warm and pressure for 3-4 hours, finally releasing pressure, and bleaching water to take out after pressure is released; (3) drying to cause the moisture content of the blank plate to be regulated to 5-8%; (4) anti-flaming treatment: adopting a vacuum pressurizing and impregnating method, wherein the vacuum degree is 80-87kPa, the vacuum time is 1.5-2 hours, the impregnating pressure is 0.5-0.6MPa, and the impregnating time is 2-3 hours; and (5) carrying out hot pressure at the hot pressing temperature of 120-150 DEG C and the pressure of 2.5-3MPa for 15-20 minutes. The bamboo floor prepared with the method not only has a good favorable physical performance but also has a good anti-flaming effect.

Description

technical field [0001] The invention relates to the field of bamboo floor processing, in particular to a method for preparing a flame-retardant bamboo floor. Background technique [0002] Wood-based panels are wood fiber raw materials separated into various shapes of unit materials by mechanical processing, and then combined and pressed into various boards, including medium density fiberboard, particle board, plywood and other varieties, which are widely used in furniture manufacturing and construction industries. , Interior decoration industry; however, wood-based panels are combustible materials, and there is a greater fire risk in use. In order to reduce fire hazards and increase public safety, it is very necessary to research and develop flame-retardant wood-based panels. Contents of the invention [0003] The object of the present invention is to provide a method for preparing flame-retardant bamboo flooring. The bamboo flooring prepared by the method not only has go...
