Description

TECHNICAL FIELD

[0001] The utility model relates to fiberboard technical field, concretely is a fiberboard of close clamping. BACKGROUND

[0002] The existing fiberboard is mainly made of urea formaldehyde resin glue, since the free formaldehyde contained in the urea formaldehyde resin has toxicity, the lower the free formaldehyde content in the resin, the smaller its toxicity. There are various methods to reduce the content of free formaldehyde in urea formaldehyde resin, the most effective method is to reduce the molar ratio of formaldehyde to urea, but reducing the amount of formaldehyde will bring the disadvantages of complex urea formaldehyde resin production process, difficult end point control, prolonged resin curing time and reduced resin bonding strength and storage stability. Therefore, the common practice is to cut the fiberboard to the required size, wrap it completely with PP, PE, PET and other surface materials to make medium density fiber laminated board, and try to avoid the release of free formaldehyde through sealing means. However, such surface wrapping method still needs to apply a large amount of glue to the contact surface between the surface material and the medium density fiber layer, and if the surface material is damaged during use, more free formaldehyde may be released.

[0003] Therefore, the utility model provides a fiberboard of close clamping. CONTENT
