脆性材料加工液
Document Type and Number:
Japanese Patent JP6860266
Kind Code:
B2
Abstract:
The present invention relates to a brittle material processing liquid which contains water, (A) one or more substances selected from the group consisting of acetylene glycols having an HLB value of from 4 to 12 (inclusive) and alkylene oxide addition products of the acetylene glycols having an HLB value of from 4 to 12 (inclusive), and (B) a nonionic surfactant which is an ethylene oxide addition product having an HLB value of 6 or more and a number of moles of added ethylene oxide in the molecular structure of 5 or more, and which does not have an acetylene group, and wherein: the content of the component (A) is from 0.010% by mass to 0.200% by mass (inclusive) based on 100% by mass of the total of the brittle material processing liquid; the content of the component (B) is from 0.020% by mass to 0.500% by mass (inclusive) based on 100% by mass of the total of the brittle material processing liquid; and the content ratio of the component (A) to the component (B), namely (A)/(B) is from 0.05 to 2.00 (inclusive) in terms of mass ratio. The present invention also relates to a method for producing this brittle material processing liquid.
