Abstract
PURPOSE: An adhesive composition that is made by adding a propylene carbonate to a water-soluble phenolic resin as a curing agent, thus being suitably used for particle boards, because of its curability in a short time at low temperature and its increasing of the physical properties such as flexural strength.
CONSTITUTION: Phenol and formaldehyde at molar ratio of 1/(1.5W2.5) are adjusted in pH to 10.0W12.0 with a strong alkali such as sodium hydroxide and the reaction is effected at 70W100°C for 1W5hr to give, e.g., a water-soluble phenolic resin of 35W45wt% concentration. Propylene carbonate is added to the resultant phenolic resin by 1W5wt% to produce the objective adhesive composition.
