Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with specific embodiments.

[0013] The formaldehyde-free fiberboard of the present invention is made of wood fibers and adhesives cured by hot pressing, wherein the diameter of wood fibers is less than 0.5 mm, and the content of adhesives is 250-350 kg / m 3 , such as 250kg / m 3 、300kg / m 3 、350kg / m 3 etc. are optional dosages, and neither the wood fiber nor the adhesive contains formaldehyde.

[0014] The tools and equipment used in the preparation method of the present invention are commonly used fiberboard production equipment (such as cold presses, hot presses, glue mixing machines, glue spraying machines, paving machines, sanding machines, edge sawing machines, etc.).

[0015] The material is fiber of any wood species, and the adhesive is vinyl acetate and isocyanate or other formaldehyde-free adhesives or formaldehyde-free rubber powder, granules, and strips.

[0016] The specific proc...
