Overview of wood glue powder (II)

Mar 30,2019

Many years later, many new adhesives emerged, such as ethylene With the development of the petrochemical industry, many new adhesives emerged in large quantities, and the continuous modification of old varieties, so that the wood-based panel industry and furniture industry have developed rapidly.

As far as the production of wood-based panels is concerned, it has developed from only the production of plywood to the production of fiberboard, particle board, joinery, various decorative sticker boards and other wood glued products. The performance of these products far exceeds that of wood. For example, the veneer impregnated with phenolic resin glue, after drying, under high temperature and high pressure conditions, the wood layered plastic made of wood changes the physical and chemical properties of wood, so that it has excellent characteristics such as hard texture, heat resistance, anti-corrosion, and flame resistance.

Wood-based panels such as plywood, particle board and joinery board produced with urea-formaldehyde resin rubber powder also have the characteristics of large amplitude, smooth surface, not easy to warp and deform, high gluing strength and good water resistance, which are also unmatched by wood. In particular, vinyl woodate hot melt resin glue, phthalic acid dipropylene resin glue, etc., make the products of decorative reprocessing (that is, secondary processing of wood-based panels) on the surface of wood-based panels more colorful, and the use value of materials is significantly improved, opening up a broad future for the development of wood-based panel industry and furniture industry. Therefore, synthetic resin adhesives basically replace protein adhesives such as soybean gum and blood glue. In particular, urea-formaldehyde resin rubber powder not only has excellent performance, but also creates mechanization and automation of wood-based panel production, low cost, easy to use, and rich sources of raw materials. Therefore, the output has increased rapidly and has become the main adhesive for the production of wood-based panels in China. So far, according to incomplete statistics, adhesives for wood processing production, accounting for about the total output of national adhesives, synthetic resin adhesives are the most promising adhesives, and it is an inevitable trend to replace protein adhesives in the future.

With the needs of the development of wood-based panel industry and furniture industry, higher technical requirements for adhesives continue to be put forward, in contrast, the current synthetic resin adhesives, there are still many deficiencies, mainly: most adhesives are solvent-based and emulsion-based, in the completion of glue, to a certain drying time, and transportation and storage is inconvenient, some have the risk of poisoning and fire, and some are two-liquid type (add curing agent when used), inconvenient to use; The range of changes in the bonding conditions of the adhesive is small, which limits the application range of the adhesive; Formaldehyde-based adhesives also have serious shortcomings of formaldehyde pollution and damage to human health.

According to the above shortcomings and shortcomings, the future development trend of wood adhesives is to develop in the direction of solid adhesives such as surface powder, film, hot melt microfilm, solvent-free and formaldehyde-free adhesives.
