Problems solved by technology

[0017] The surfactant shown in Molecular Formula 2 is modified by ethoxylation of the surfactant of Molecular Formula 1. After such modification, the compatibility of the surfactant has been improved to a certain extent, but the efficiency of reducing the surface tension It has declined, but the compatibility is still not ideal when the degree of ethoxylation is low. When the degree of ethoxylation is high, the surface tension rises rapidly, and at the same time, the foaming performance is high, and the scope of use is limited.

Abstract

The invention provides a multifunctional surfactant composition for a water-based system and a preparation method thereof. The surfactant composition used in formulas of a water-based coating, ink, adhesive and a digital material has low foaming effect and has the effect of effectively reducing the dynamic surface tension of the water-based system. The composition is formed by compounding and modifying based on alkynyl diol or alkynyl diol ethoxylate. The key component structure of the composition is an alkane structure in which R, R1 and R2 are straight-chained or branch-chained, and the number of carbons is 1 to 15; R, R1 and R2 can be the same or different groups; the carbon number of the alkane structure in which R, R1 and R2 are straight-chained or branch-chained is 1 to 15; R, R1 and R2 can be the same or different groups; and the sum of m and n is 1 to 30. The invention simultaneously provides the preparation method for the composition.

Description

technical field [0001] The invention relates to a surfactant composition, which is used in water-based coatings, inks, adhesives and digital material formulas, and has the functions of low foaming and effectively reducing the dynamic surface tension of water-based systems. technical background [0002] With the continuous depletion of non-renewable resources oil and coal, people have attached great importance to the utilization of renewable resource water. Many solvent-based product systems have been converted to water-based systems. For example, water-based coatings, inks, adhesives, digital materials and other products have become water-based very quickly in recent years. The use of surfactants is essential in the research and development of water-based products. Surfactants are used to reduce the surface tension of water to achieve the purpose of product coating and dispersion. [0003] However, most surfactants can only reduce the static surface tension of water, so wat...
