AI Technical Summary

Technical Problem

The printing and paper industries face challenges with water-based inks, which have slower drying speeds and lower production rates compared to solvent-based inks, necessitating surfactants that enhance surface tension reduction, wettability, permeability, and dispersibility to accommodate high-speed printing and coating.

Method used

A biomass water-soluble surfactant composition is developed, comprising specific acetylene glycol and/or its ethoxylated forms blended with polyoxyalkylene-added nonionic surfactants, which exhibits excellent defoaming and dispersibility properties, low dynamic surface tension, and high water solubility, making it suitable for high-speed printing and coating while being environmentally friendly.

Benefits of technology

The surfactant composition significantly improves wettability, permeability, and defoaming properties of inks and paper coating agents, enabling high-speed printing and coating while maintaining a high biomass degree, thus addressing environmental concerns.

Abstract

The purpose of the present invention is to provide: a biomass water-soluble surfactant composition, which, as a result of having excellent solubility in water, exhibiting excellent defoaming properties and dispersibility, and having low dynamic surface tension, imparts excellent wettability and permeability, and which also takes solubility in water and environmental problems into consideration; and an ink and a paper coating agent into which said composition is blended. Provided is a water-soluble surfactant composition comprising (A) an acetylene glycol represented by formula (1) (in the formula, R1 and R2 each represent a 1-5 carbon alkyl group) and / or an ethoxylated acetylene glycol represented by formula (2) (in the formula, R3 and R4 each represent a 1-5 carbon alkyl group, m and n are each a positive number of 0.5-25, and m+n is 1-40), and (B) a polyoxyalkylene addition-type nonionic surfactant comprising at least one bio-derived polyoxyalkylene addition-type nonionic surfactant, the water-soluble surfactant composition having a biomass degree of 10% or more according to ASTM-D6866-22.
