Description

Technical field: [0001] The invention relates to a building material, in particular to a tea seed shell plywood which can replace wood and protect cultivated land and a production method thereof. Background technique: [0002] With the progress of society, the improvement of people's living standards, and the vigorous development of the construction industry, the demand for wood and bricks is unprecedentedly strong. However, my country's forest resources (coverage rate is only 10.7%) and cultivated land are very limited (burning bricks consumes more than 100,000 mu per year). In order to protect the ecology, a plan to return farmland to forests has even been proposed. Therefore, we urgently need building materials that can replace wood and brick. Although there are many kinds of medium density plywood at present, its raw materials are mostly wood, wheat straw, cotton straw, sunflower straw, rice straw, etc. The shortage of wood will inevitably lead to high raw material cos...

According to measurements, during the production process, the volatile phenol content in wastewater is as high as 0.9-1.8%. Although the cost of phenolic glue is relatively low, the consequences of serious environmental pollution cannot be ignored.

Phenolic glue will also cause toxic damage to users during use
