Patent ID: 8153550

Claim:
A process of manufacturing an oil adsorption foaming sheet, the oil adsorption foaming sheet manufacturing process comprising: mixing polyurethane prepolymer of 15-17 wt % with peat moss cement of 80-82.8 wt % which is obtained by removing foreign matters from peat moss having a moisture content of 10-50 wt % and making the peat moss pass through a 100-mesh screen, lecithin of 1-2 wt % as a dispersion and surfactant agent, N-methylmorpholine of 1-1.5 wt % as a foaming agent, and triethyleneamine of 0.2-0.3 wt % as a catalyst, to thereby form a foaming composite; forming the foaming composite to thereby obtain a block-shaped polyurethane foaming body; slicing the block-shaped polyurethane foaming body to then be made into sheets of a desired thickness; and drying the sliced sheets into a moisture content of 2 wt % or below.
