Clay inhibitor as well as preparation method and application thereof

Abstract

The invention provides a clay inhibitor which is prepared by uniformly mixing an organic cationic compound A and a polyol amine compound B in a mass ratio of (1-5):1 at normal temperature. The invention also provides a preparation method of the clay inhibitor and an application of the clay inhibitor in inhibiting clay side effects. The clay inhibitor is simple in preparation process, is convenient to use and is low in cost; and the organic cationic compound and the polyol amine compound contained in the clay inhibitor achieve a synergistic effect, so that the negative impact of clay on the performance of a polycarboxylic acid water reducer is effectively reduced.

Description

technical field

[0001] The invention belongs to the field of preparation of concrete superplasticizer additives, and in particular relates to a clay inhibitor for suppressing side effects of clay and a preparation method thereof. Background technique

[0002] In recent years, the scale of my country's infrastructure projects has been huge, and high-speed railways, highways, large bridges, hydropower projects, and urbanization have advanced rapidly, and the amount of concrete used has accounted for more than half of the world's total. However, with the rapid development of engineering construction, the consumption of sand and gravel aggregates is huge, and high-quality natural sand and gravel resources are increasingly scarce; especially in remote and arid areas, sand and gravel aggregates cannot be effectively cleaned, making sand and gravel aggregates in some areas The mud content gradually increased. Therefore, machine-made sand has gradually been widely used in concrete,...
