CUT-WORKING METHOD OF MATERIAL HAVING ADHESION PART

摘要

PURPOSE:To carry out the cutting work smoothly without causing any cracks or chips by forming an adhesion part through a 2-cyanoacrylate instantaneous adhesive blended with a specific carbonate compound. CONSTITUTION:As a carbonate compound, a carbonate compound is used that is selected from a group consisting of dialkylcarbonate, alkylenecarbonate, alkyleneglycolbisalkylcarbonate and triatomic alcohol trisalkylcarbonate. These carbonate compounds can be blended into 2-syanoacrylate in single state respectively, and also can be blended in two kinds or more. The blending quantity of a carbonate compound is suitable to be 20-400 pts.wt., in particular, 25-300 pts.wt., especially, 30-300 pts.wt., with respect to 100 pts.wt., of 2-cyanoacrylate. When the blending quality of a carbonate compound is less very much, a cutting work ability becomes insufficient, on the contrary, when it is much extremely, the adhesive forces become low. To 2-cyanoacrylate, an additive such as a preservation fixture or the like can be added appropriately other than a carbonate compound.
