Abstract
The present invention relates to a method for manufacturing processed cork chips, and a floor construction method using the same. The processed cork chips are manufactured by the method, including: crushing and drying cork chips; adding polyurea to the dried cork chips to prepare a mixture; heating the mixture to cure the same; and cooling the cured mixture. Further, the floor construction method includes: laying the processed cork chips on the surface of a floor formed of concrete, a water-permeable base layer or crushed stone with a solidified top surface; and flattening the processed cork chips and pressing the same by means of a roller at a fixed temperature.
Claims3
A method for manufacturing processed cork chips, comprising:
- crushing and drying cork chips;
- preparing a mixture by adding silylated polyurea having an isocyanate terminal to the crushed and dried cork chips to prepare the mixture;
- heating the mixture to cure the mixture and form a cured mixture, including kneading the cork chips admixed with the polyurea at 100 to 200 rpm and heating the mixture at 60 to 80° C. for 30 minutes to 1 hour;
- and
- cooling the cured mixture, including by introducing external air at room temperature for 30 minutes to 1 hour while kneading the cured mixture at 50 to 00 rpm.
