Embodiment 1

[0021] First, select bamboo slices with a width of 18-25mm, remove the green and yellow bamboo; cut the bamboo slices into bamboo slices with a thickness of 3-6mm; dissect the bamboo slices, and cut them into uniform bamboo strips with a width of 4-6mm. Finally, put the bamboo into the pressure vessel, control the temperature at 130°C and the pressure at 3kg / cm 2 , continue for 2 hours for degreasing, desugaring and carbonization treatment; dry the treated bamboo strips at 60°C, and control the moisture content below 10%; take out the bamboo strips and immerse them in glue with a glue concentration of 58-60%, soak them 2 minutes until the surface of the bamboo slab is covered with glue; the soaked bamboo slab is dried at 60°C until the moisture content is 14-16%; the dried bamboo sieve is pressed through a cold press and a mold square material; put the pressed square material together with the mold into a curing kiln at a temperature of 125°C, and cure for 10 hours; take off t...

Abstract

The invention discloses a preparation method of an anti-wrinkle and anti-cracking bamboo floor. Take bamboo slices with a width of 18-25 mm, layer the surface bamboo green and bamboo yellow through a green cutting machine, and plan the bamboo yellow to obtain a thickness of 3. ~6mm bamboo slices, the obtained bamboo slices are dissected again, cut into bamboo strips with a width of 4~6mm, the bamboo strips are degreased and desugared by high temperature and high pressure, and finally the bamboo strips are dried to a moisture content of less than 10% for soaking Glue, soaked bamboo strips are dried again, after curing, the dried bamboo strips are pressed and formed by cold presses and molds, and then cured at high temperature and sliced ​​to obtain slabs that can be used to produce finished flooring. The invention controls the thickness of the bamboo strips by cutting the bamboo slices into strips, can ensure uniform glue application during the glue application process, and at the same time greatly reduces the amount of glue used, shortens the drying time after glue, and reduces the energy consumption. Consumption, the finished board has higher strength, lower moisture absorption expansion rate, no wrinkling, cracking, wire jumping, etc., and the bamboo strips in the entire bamboo floor will not break the silk road.

Description

technical field [0001] The invention belongs to the field of bamboo and wood industry, and in particular relates to a preparation method of an anti-wrinkle and anti-crack bamboo floor. Background technique [0002] Bamboo floor is a new type of building decoration material. With its natural advantages and many excellent properties after molding, bamboo floor brings a green and fresh wind to the building materials market. Bamboo flooring has the natural texture of bamboo, fresh and elegant, and the water absorption expansion rate of bamboo flooring is much smaller than that of wood flooring. Even after long-term use, it will not produce local swelling and unevenness. [0003] However, at present, most of the production methods of bamboo flooring adopt bamboo silk pressing. After the bamboo silk is pressed, it will cause skipping and wrinkling, resulting in uneven local density. floor toughness. Contents of the invention [0004] Purpose of the invention: the purpose of th...
