A kind of polyether composition

Abstract

The invention relates to a polyether composition, which comprises polyether, branched modified polyether, linear modified polyether and solubilizer. These components are mixed by a certain process to form a transparent polyether composition, which can have good foam control performance and surface control performance in coatings, inks and other systems, and can also be used in sewage treatment and landfill leachate. .

Description

technical field [0001] The invention relates to a polyether composition and a preparation method thereof, belonging to the technical field of fine chemicals. Background technique [0002] In today's social environment, environmental protection has reached an unprecedented height, permeating all aspects of life. There is no doubt that the safety and environmental protection of living places is a major issue related to personal health. [0003] The paint industry plays a very important role in the national economy. In the past two years, under the "high pressure" of environmental protection, many cities have implemented "oil" to "water", and water-based coatings have mushroomed like mushrooms. [0004] Water-based coatings generally consist of water-based binders, pigments, fillers, dispersants, thickeners, wetting agents, leveling agents, and defoamers. Wetting agents, leveling agents, and dispersants are all surfactants. During the process of grinding and dispersing coatin...

Problems solved by technology

The patent of CN102527096A introduces a preparation method of organosilicon defoamer. On the basis of polyether modified organosilicon, polyether groups with dendritic structure are grafted on the main chain of organosiloxane to solve the problem of defoaming agent. Poor bubble rate and temperature sensitivity issues

Moreover, these products only have the function of foam control, and the contribution to wettability and leveling is almost zero
