Method for producing polylactic acid hot melt adhesive |
| abstract |
[Problem] To provide a production method capable of easily preparing a polylactic acid-based hot melt adhesive having thermal stability that can withstand practical use. A method for producing a polylactic acid-based hot melt adhesive comprising: (1) at a temperature of 180 to 280 ° C., 0.02 to 0.3 parts by weight of a dithiocarbamate and 10 to 100 parts by weight of a plasticizer. After adding 100 parts by weight of the first polylactic acid having a relative viscosity of 2.5 to 4.0 to the mixed solution and melt mixing, 1 to 10 parts by weight of phosphite ester and 1 to 10 parts by weight of hindered phenol A step of adding and preparing a first polylactic acid composition having a viscosity measured at 180 to 220 ° C. of 70 to 700 mPa · s, (2) the first polylactic acid composition having a viscosity of 180 to 280 ° C. A method comprising a step of mixing a second polylactic acid having a relative viscosity at a temperature of 2.5 to 4.0 in an amount such that the weight ratio of the first polylactic acid / the second polylactic acid is 2/8 to 8/2.
