Problems solved by technology

Although the dry strength of medium density fiberboard (MDF) is also tested, because the UF resin used in it is not dehydrated (the content of free formaldehyde in the glue is high), and the amount of glue used is slightly higher than that of particleboard, therefore, the same amount of F / U substance Compared with UF resin, the production of particleboard can reach the E2 level, but the production of MDF cannot reach the E2 level.

Description

technical field [0001] The invention relates to adhesive technology, in particular to a preparation method of an adhesive for wooden furniture. Background technique [0002] At present, the global output of wood adhesives accounts for about 3 / 4 of the total output of adhesives. With the development of the modern wood processing industry, the amount of wood adhesives is not only increasing and the variety is increasing, but also its amount has become a measure of the technological development of a country or a region's wood industry. Significant sign of level. With the improvement of people's living standards and environmental requirements, the development of environmentally friendly and non-toxic wood adhesives is the mainstream of development today... Adhesives used in wood processing in my country are mainly two major areas: wood-based panel manufacturing and wood product production. Since the Chinese government enforced the GB1858O-2001 national standard on July 1, 2002,...
