Embodiment 1

[0058] Embodiment 1: a kind of bamboo-wood composite panel production method, it comprises the following steps:

[0059] (1) Preparation of core board and surface board,

[0060] ① The preparation of the core board includes the following steps in turn:

[0061] a. The air-dry density is selected as 0.45g / cm 3 Poplar, the selected wood is crushed to obtain wood particles with a particle size of 2 to 5 mm;

[0062] b. Dry the prepared wood pellets. First, put the wood pellets on a natural drying site. When the air-dried to a moisture content of 35%, send them into a drying kiln for forced drying. Control the humidity in the drying kiln to 70% for 6 days , control the temperature on the first day at 50°C, and maintain a daily heating rate of 10°C until the temperature reaches 100°C, reducing the moisture content to 9%; in order to balance the moisture content among the wood particles, it is necessary to Carry out the moisture content balance step, that is, put the dried wood p...

Embodiment 2

[0081] Embodiment 2: a kind of bamboo-wood composite board production method, it comprises the following steps:

[0082] (1) Preparation of core board and surface board,

[0083] ① The preparation of the core board includes the following steps in turn:

[0084] a. The air-dry density is selected as 0.55g / cm 3 For fir, the selected wood is pulverized to obtain wood particles with a particle size of 3 to 6 mm;

[0085] b. Dry the prepared wood pellets. First, put the wood pellets on a natural drying site. When the air-dried to a moisture content of 35%, send them into a drying kiln for forced drying. Control the humidity in the drying kiln to 80% for 5 days , control the temperature on the first day to 60°C, and maintain a daily heating rate of 10°C until the temperature reaches 100°C, reducing the moisture content to 10%; in order to balance the moisture content among the wood particles, it is necessary to Carry out the moisture content balance step, that is, put the dried w...

Embodiment 3

[0104] Embodiment 3: a kind of bamboo-wood composite board production method, it comprises the following steps:

[0105] (1) Preparation of core board and surface board,

[0106] ① The preparation of the core board includes the following steps in turn:

[0107] a. The selected air-dry density is 0.65g / cm 3 Pine wood, the selected wood is crushed to obtain wood particles with a particle size of 1 to 5mm;

[0108] b. Dry the obtained wood pellets. First, put the wood pellets on a natural drying site. When air-dried to a moisture content of 35%, send them into a drying kiln for forced drying. Control the humidity in the drying kiln to 90% for 5 days , control the temperature on the first day to 60°C, and maintain a daily heating rate of 10°C until the temperature reaches 100°C, reducing the moisture content to 11%; in order to balance the moisture content among the wood particles, it is necessary to Carry out the moisture content balance step, that is, put the dried wood parti...

Abstract

The invention relates to a method for producing a building composite rubber plate, in particular to a method for producing a bamboo-wood composite board. The method for producing the bamboo-wood composite board is implemented by the following technical scheme that the method for producing the bamboo-wood composite board comprises the following steps of: (1) preparation of a core board and a surface board; and (2) compounding process of the core board and the surface board. The bamboo-wood composite board prepared by implementing the method disclosed by the invention has the advantages of low buckling deformation and high static bending strength.

Description

technical field [0001] The invention relates to a production method of a building material composite rubber board, in particular to a production method of a bamboo-wood composite board. Background technique [0002] my country is a Shaolin country, and the per capita forest volume is less than 9.1m 3 , Timber supply and demand is very tight. In recent years, with the rise of the interior decoration industry, the demand for wooden flooring has increased sharply, but for a long time, my country's wooden floor manufacturing materials have been dependent on imports from Southeast Asia, Africa and other places. However, with the global emphasis on the ecological environment in recent years, various timber exporting countries have reduced and restricted log exports. This has caused a shortage of raw materials for wooden flooring and an increase in its price, prompting consumers to give priority to non-solid wood flooring with more reasonable prices, such as bamboo flooring, when...
