Anti-mud agent and preparation method thereof

Abstract

The invention provides an anti-mud agent and a preparation method thereof. The anti-mud agent is prepared from the following raw materials: a polymer and sylvite with free potassium ions, wherein a weight ratio of the polymer to the sylvite is 1:1, the polymer is prepared from the following raw materials in parts by weight: 17% of a water-soluble cationic polymeric monomer, 17% of a water-solublepolymeric small monomer, 17% of a polymeric monomer with a large group, 2% of an emulsifier, 0.1% of an initiator and 46.9% of water. By applying the anti-mud agent, the mixing amount of the anti-mudagent can be reduced, so that the production cost is reduced.

Description

technical field [0001] The application relates to the technical field of chemical production and processing, in particular to an anti-mud agent and a preparation method thereof. Background technique [0002] Polycarboxylate superplasticizers are more sensitive to mud in aggregate, because clay will weaken the cement dispersibility of polycarboxylate superplasticizers, reduce the fluidity of mortar, and accelerate the slump loss of concrete, so the polycarboxylate superplasticizer is limited. The development of water reducing agent in the field of construction. [0003] Since the montmorillonite in the clay has an intercalation structure composed of aluminosilicate, it will cause the oxygen atoms in the side chain groups in the polycarboxylate superplasticizer to form hydrogen bonds with the water molecules between the layers. The structure of montmorillonite and polycarboxylate superplasticizer is as follows figure 1 As shown, the hydrogen bond will make the polycarboxylat...

AI Technical Summary

Problems solved by technology

[0005] However, the amount of anti-mud agent used in the prior art is large, resulting in high cost, and even has an impact on the later stage of concrete (for example, high filler will affect concrete strength, etc.)
