Background
China is one of the major countries for producing artificial boards, and the data of 'national forestry and grassland development statistical bulletin' in 2018 shows that the total yield of artificial boards in the country in 2018 is 29909m3, and the increase is 1.44% on year-on-year basis. The artificial board as the substitute of wood product has the advantages of better structure and physical mechanical property than natural wood, and the continuous rise of yield and sales volume in recent years makes the industry in a vigorous development situation. Under the influence of the continuous high-speed development of Chinese economy, the Chinese artificial board industry has great development space and broad prospect along with the falling of a large number of new houses, the reconstruction of old houses and the updating and upgrading of home and office furniture. However, under the conditions that the climate change is concerned globally, the worldwide available forest resources are reduced day by day, and the demand of social and economic development on wood and products thereof is increased continuously, artificial fast-growing commercial forests, forest cultivation and felling residues, and waste wood fibers in the production, construction, updating and transformation processes, including crop straws and other resources, are fully utilized to develop artificial boards so as to replace traditional wood products, and the main development trend of future artificial boards is formed. Meanwhile, in the quality of the traditional artificial board, the artificial board is not environment-friendly, has poor fireproof, waterproof and pressure-resistant performances, is easy to deform and enter water in the using process, even causes fire, and has great potential safety hazard, so that a novel perlite composite artificial board is needed to replace the existing artificial board.
