Problems solved by technology
[0004] The traditional straw wood-based panels are pure straw wood-based panels, that is, the wood-based panels are completely made of straw raw materials. However, pure straw wood-based panels have problems such as poor shape and low strength, and it is difficult to meet the national standard for particleboard.
In addition, research on wood-based panels with straw on the surface and wood on the core is also underway. However, in this wood-based panel, the core is completely made of wood, and a large amount of wood still needs to be used, which does not meet the national environmental and forest regulations.

Abstract
The invention provides an artificial board comprising a surface layer and a core layer. The surface layer comprises, by weight, 4-8% of adhesives, 0-10% of auxiliaries, and the balance straw. The corelayer comprises, by weight, 3-7% of adhesives, 0-10% of auxiliaries, and the balance core layer mixtures, wherein the core layer mixtures comprise straw and wood.
Description
technical field [0001] The invention relates to the field of wood-based panels, in particular to a wood-based panel mixed with straw and wood. Background technique [0002] At present, my country's wood-based panel manufacturing is still dominated by wood raw materials. However, due to the country's protection of the environment and forest resources, the use of wood-based panels is gradually restricted, while the society's demand for wood-based panels is constantly increasing. Therefore, many wood-based panel manufacturers are caught in the plight of shortage of wood resources. [0003] Crop straw is a valuable renewable resource, and the annual output of crop straw in my country is about 700 million tons. However, due to the influence of factors such as consumption concepts and lifestyles, my country's straw resources have been in a state of high consumption, high pollution, and low output for a long time, and a considerable part of crop straws have been abandoned or burne...
