Title:
METHOD FOR PRODUCING WATER-PERMEABLE BLOCK USING RECYCLED SYNTHETIC RESIN, AND WATER-PERMEABLE BLOCK PRODUCED BY SAID METHOD
Document Type and Number:
WIPO Patent Application WO/2018/186567
Kind Code:
A1
Abstract:
Disclosed are a method for producing a water-permeable block using recycled synthetic resin, and a water-permeable block produced by the method. The production method comprises: (S10) a fine aggregate heating step for feeding fine aggregate into a primary heating furnace and heating at a set temperature; (S20) a fine aggregate temperature maintenance step for feeding the heated fine aggregate into a secondary heating furnace and maintaining so that the temperature to which the fine aggregate has been heated is maintained as a constant; (S30) a melting step for feeding, into a melting furnace, fine aggregate discharged from the secondary heating furnace and recycled synthetic resin pulverized to a set size, and melting the recycled synthetic resin by means of the temperature of the fine aggregate; (S40) a mixing step for feeding molten resin and fine aggregate into a mixer and mixing the fine aggregate and melted recycled synthetic resin, wherein the mixer is heated so that the temperature therein is 220-290℃, and is rotated at the rotational speed of 10-30rpm; (S50) a molding step for feeding the mixed molten resin and fine aggregate into a mold and molding the water-permeable block by compression-molding at 30-40MPa; and (S60) a cooling step for evenly cooling the surface and interior of the molded water-permeable block for 15-20 seconds.
