Problems solved by technology

[0003] my country produces about 700 million tons of various crop straws every year, of which wheat straw and rice straw account for about 40% to 60%; most of them are treated by incineration and burial, and have not been utilized, and the straw will increase carbon dioxide in the process of burning emission

Embodiment Construction

[0036] Examples, see attached figure 1 , a wheat straw board with an oriented structure, comprising a board body, the thickness of the board body is 12mm, and it has a layered structure, which consists of wood grain paper layer 1, wear-resistant paper layer a2, base layer 3 and wear-resistant paper from top to bottom Layer b4; the material of the base layer is wheat straw, and a multi-layer structural board formed by using wheat straw as a raw material and using modified isocyanate resin as an adhesive after directional paving and hot pressing; one end of the board body is set There is a locking male slot 5, and the other side is provided with a locking female slot 6.

[0037] The four sides of the board body are edge-sealed with white transparent granular wax 7, which is moisture-proof and not afraid of water.

[0038] The process flow of the present invention is: base material health preservation—hot pressing—cooling plate—stacking—semi-finished product health preservation—...

Abstract

The invention relates to an oriented structural straw board, which comprises a board body, wherein the board body is of a laminar structure and comprises a grainy paper layer, a wear resistant paper layer a, a basement layer and a wear resistant paper layer b from top to bottom in sequence; the basement layer is made of wheat straw, and is a multi-layer structural board formed by oriented pavement and hot pressing with the wheat straw as a raw material and modified isocyanate resin as a bonding agent; a male latch groove is arranged on one end of the board body, and a female latch groove is arranged on the other lateral surface; the periphery of the board body is sealed by white transparent granular wax; and the board body is 12 mm thick. The oriented structural straw board has the advantages of high structural strength, reliable bearing behavior, better waterproof performance of a board surface than the conventional wood board, durability, worm resistance, low formaldehyde release, environmental friendliness, low carbon and increase of rural income.

Description

Technical field: [0001] The invention relates to the field of medical auxiliary equipment, in particular to a wheat straw board with an oriented structure and a preparation method thereof. Background technique: [0002] China's timber felling accounts for about 70% of the world's total, and most of it is used on construction sites. At the same time, construction accounts for almost 40% of the total carbon dioxide emissions, which is much higher than that of transportation and industry. . [0003] my country produces about 700 million tons of various crop straws every year, of which wheat straw and rice straw account for about 40% to 60%; most of them are treated by incineration and burial, and have not been utilized, and the straw will increase carbon dioxide in the process of burning emission. In order to protect forest resources and reduce carbon dioxide emissions, the "waste" in the eyes of farmers is fully utilized, and straw needs to be reused. Invention content: ...
