Title:
MANUFACTURE OF MODIFIED LUMBER
Document Type and Number:
Japanese Patent JP3553660
Kind Code:
B2
Abstract:
PURPOSE: To contrive improvements in dimensional stability, durability, an external appearance, by a method wherein a medical fluid produced by mixing an acrylic compound and cyclic ester compound with each other is infiltrated into lumber, which is heated and hardened.
CONSTITUTION: A medical fluid is constituted by mixing methyl methacrylate and benzoyl peroxide as an acrylic compound and toluene of cyclic ester with each other and the medical fluid is infiltrated into lumber by a reduced pressure pressurizing method so that a degree of infiltration or nonvolatile content becomes 20%. Then the modified lumber is manufactured by heating and hardening within a hot air dryer at 120°C. Therefore, irrespective of a low degree of infiltration, the modified lumber can be made into a matter wherein it is hard to crack and superior in dimensional stability, strength physical properties and since the degree of infiltration is low, an external appearance can be improved.
