In the list of carcinogens published by the world health organization international agency for research on cancer, formaldehyde is placed on a list of carcinogens.
In recent years, with the increase of international market competition pressure, the environmental protection grade of the artificial boards is continuously improved, and the environmental protection consciousness of global citizens to home life is continuously enhanced, and a plurality of domestic artificial board manufacturers are concerned with the development and popularization of environmental protection products and occupy certain market positions. Although many synthetic resins with low trace formaldehyde emission are being developed, many complex problems arise during the research process. In addition, as the energy crisis of all countries in the world continuously appears, the price of the synthetic resin is continuously increased, the research cost is higher, the product competition is weak, and the manufacturers are difficult to break through the bottleneck of export. Therefore, under various pressures in the present society, wood adhesives modified or modified with renewable materials, particularly with grain-based seed proteins, have become a research hotspot of researchers.
