Method of making a degradable composite article |
| abstract |
A method of manufacturing disposable tableware products is taught using a degradable composite material including the following components by weight in parts: a plant fiber, 60-90 parts; a urea-formaldehyde resin, 10-35 parts; a melamine resin, 3-10 parts; and a food coloring agent, 1-10 parts; wherein the molecular weight of said urea-formaldehyde resin is 300-600, including: (1) pulverizing the plant fiber into 60 mesh or over and thoroughly mixing the plant fiber with the urea-formaldehyde resin and the melamine resin proportionately to form a mixture of the degradable composite material; (2) feeding the mixture of the degradable composite material into a concave molding mould positioned in an operating platform of a hydraulic press wherein the press is capable of moving in an upward direction in a fixed quantity and position; maintaining the temperature of the mould at 125-190° C.; and (3) controlling a pressure of the pushing-upward-type oil hydraulic press at between 10-30 Mpa; and operating the press at 3 intervals for 3-30 seconds per interval by maintaining at the pressure so as to obtain the finished products. |
