Abstract

The present disclosure relates to a method of molding a combustible heat source and provides a method of molding a combustible heat source, the method including: step S1 of preparing a combustible heat source composition including a carbon powder, an organic binder, and an ignition accelerator, step S2 of treating glycerin or propylene glycol on the combustible heat source composition; and step S3 of compressing and molding the composition after the treatment, in which the compressing in step S3 is performed at a strength of 0.5 to 10 MPa.

1 . A method of molding a combustible heat source, the method comprising:
 step S1 of preparing a combustible heat source composition comprising a carbon powder, an organic binder, and an ignition accelerator;   step S2 of treating glycerin or propylene glycol on the combustible heat source composition; and   step S3 of compressing and molding the composition after the treatment, wherein step S3 is performed at a pressure of P O , and   the P O  is 1.5 to 2 times greater than a compression strength P w  in a case where moisture is treated.   
     
     
         2 . The method of  claim 1 , wherein the heat source has a diameter of 7 to 8 millimeters (mm) and a length of 10 to 12 nanometers (nm). 
     
     
         3 . The method of  claim 1 , wherein the P O  is 0.5 to 10 megapascals (MPa). 
     
     
         4 . The method of  claim 3 , wherein the P O  is 1.5 to 3.0 MPa. 
     
     
         5 . The method of  claim 1 , wherein the P w  is 0.5 to 1.5 MPa. 
     
     
         6 . The method of  claim 1 , wherein the oil is treated in an amount of 0.8 to 2 parts by weight with respect to 100 parts by weight of a solid content of the combustible heat source composition. 
     
     
         7 . A combustible heat source molded by the method of molding a combustible heat source according to  claim 1 . 
     
     
         8 . The combustible heat source of  claim 7 , wherein the heat source is ignited within 30 seconds, and combustion continues for 140 seconds or longer. 
     
     
         9 . A smoking article comprising the combustible heat source of  claim 7 .
