This research focused on the problem of the high thickness swelling (TS) rates of laminate fl oor covering, and proposed modifi ed manufacturing technology for fi berboard substrates with low thickness swelling. The authors explored the effects of adhesive adaptability and hot press technology on the performance. The results indicated that with MUF under the conditions of density 0.85 g/cm3, hot-pressing temperature at 180℃, adhesive content of 14%, and water-proof agent spread rate of 1.5%, the thickness swelling rates of fi berboard was signifi cantly lower than that of maximum in the standard, realized the manufacturing process of low thickness swelling for fi berboard substrates. The qualifi ed laminate fl oor covering products can be produced with good environmental-friendly property.
