Embodiment 1

[0023] A kind of production method of flame-retardant bamboo plywood, comprises the following steps:

[0024] (1) get fresh bamboo, remove the green bamboo on the surface of the fresh bamboo, then cut the original bamboo into 3-5 pieces, remove the yellow bamboo of the fresh bamboo inner layer and the diaphragm part of the bamboo joint after dissection;

[0025] (2) A part of the bamboo chips are squeezed by a roller press to make the bamboo chips become bamboo fiber bundles, and then the bamboo fiber bundles and another part of the bamboo chips are put into a flame retardant aqueous solution with a mass concentration of 40%. The agent is mainly made of the following mass ratio components: 45 parts of ammonium oligophosphate, 14 parts of nano-zinc oxide, 11 parts of sodium dodecylbenzenesulfonate, 6 parts of magnesium oxide powder, 13 parts of asbestos fiber, tetraboric acid 5 parts of sodium, 12 parts of dicyandiamide and 11 parts of boric acid; control the temperature of the...

Abstract

The invention discloses a production method of flame-retardant bamboo plywood. The production method includes the following steps that firstly, fresh bamboo is taken; secondly, one part of bamboo pieces are squeezed through a roll squeezer so that the bamboo pieces can become bamboo fiber bundles, and then the bamboo fiber bundles and the other part of bamboo pieces are placed in a flame retardant aqueous solution with the mass concentration ranging from 30% to 50%; thirdly, the bamboo fiber bundles and the bamboo pieces are dried; fourthly, the bamboo fiber bundles and the bamboo pieces are soaked in a viscose agent; fifthly, bamboo fiber bundle veneers and bamboo piece veneers form a blank in a laminated manner, the upper face layer and the lower face layer of the plywood blank are bamboo piece veneers, the interior of the plywood blank is formed by overlapping and compounding the multiple layers of bamboo fiber bundle veneers from top to bottom, and every two adjacent bamboo fiber bundle veneers are arrayed in the vertical texture direction or each bamboo fiber bundle veneer and the corresponding bamboo piece veneer are arrayed in the vertical texture direction; sixthly, the bamboo veneers forming the blank are subjected to pre-pressing and then subjected to hot rolling; and seventhly, cooling is conducted, the bamboo veneers are displayed in a laminated manner, and the flame-retardant bamboo plywood is obtained. The flame-retardant bamboo plywood manufactured through the production method has good flame-retardant performance and is low in glue failure rate, and strength of the plywood is high.

Description

technical field [0001] The invention relates to the field of plywood, in particular to a production method of flame-retardant bamboo plywood. Background technique [0002] Bamboo plywood is a building material made of moso bamboo as the main structure and filling material, which is formed into blanks by high pressure. Bamboo has high strength, good toughness, rigidity and wear resistance, and can be used as an excellent engineering structure material. The bamboo plywood formwork made of bamboo has good bending strength and rigidity, good overall structure, large format, convenient loading and unloading, easy demoulding, high construction efficiency, excellent technical quality and economic benefits. Due to its exquisite appearance, bamboo plywood is increasingly used for various indoor decorations. Due to its low flame-retardant level, the existing bamboo plywood is difficult to meet the requirements of building interior decoration design specifications, especially for publ...
