Embodiment 1

[0053] This embodiment provides a straw mixture wood-based panel, which is made of the following raw materials: rice straw 65-75wt%, wheat straw 15-25wt%, pine sawdust 10-20wt%, Calculate the weight percentage of each of the above components under the same water content. In the examples of the present invention, wt% means the weight percentage of the component. Among them, the respective proportions of rice straw, wheat straw and pine sawdust can be selected according to specific needs within the above-mentioned range, and the total can be equal to 100%. Since the fiber length and width of pine sawn powder are larger than those of rice straw and wheat straw, and its mechanical strength is also greater, it is possible to choose to add more or less pine sawn powder according to the purpose of the board. Preferably, the sawn powder of pine tree can be sawed powder of masson pine or sawed powder of larch or sawed powder of red pine or sawed powder of foreign pine.

Embodiment 2

[0055]This embodiment provides a straw mixture wood-based panel, which is made of the following raw materials: rice straw 67.5-70wt%, wheat straw 17.5-20wt%, pine sawdust 12.5-17.5wt% , in the case of the same water content to calculate the weight percentage of the above components. Preferably, the sawn powder of pine tree can be sawed powder of masson pine or sawed powder of larch or sawed powder of red pine or sawed powder of foreign pine.

Embodiment 3

[0057] This embodiment provides a straw mixture wood-based panel, which is made of the raw materials of the following components: rice straw 68.5wt%, wheat straw 18.5wt%, pine sawdust 13wt%, at the same water content In the case of calculating the weight percentage of each of the above components. Wherein, the pine sawn powder is red pine sawn powder.

Abstract

The invention belongs to the technical field of artificial boards, and discloses a straw mixture artificial board and a processing method. The mixture artificial board is made of raw materials of the following components: 65-75 wt% of rice straw, 15-25 wt% of wheat straw and 10-20 wt% of pine saw wood powder, and the weight percentages of the components are calculated under the condition of the same water content. The pine saw wood powder is added to the rice straw and the wheat straw to produce the artificial board, thus the mechanical strength of the artificial board is higher than the rice straw and wheat straw artificial board by 30%-40%, and the nail holding force of the mixture artificial board is larger than that of the straw artificial board.

Description

technical field [0001] The invention relates to the technical field of artificial boards, and more specifically relates to a straw mixture artificial board and a processing method thereof. Background technique [0002] my country is the world's largest producer and consumer of wood-based panels, with a total output of 100 million cubic meters of wood-based panels. Due to the shortage of forest resources in my country and the tight supply of wood, some manufacturers of wood-based wood-based panels are facing the threat of reducing production, stopping production or changing production. [0003] my country is also a large agricultural country, with an annual output of about 800 million tons of crop straw, of which 400-500 million tons are rice and wheat straw. The traditional way of dealing with these large amounts of rice and wheat straw is to burn it on the spot or pile it up to make it rot, which has caused serious environmental pollution and other problems. [0004] At p...
