Concrete base wet-curing anticorrosive adhesive material and preparation method thereof

Abstract

The invention relates to a concrete base wet-curing anticorrosive adhesive material and a preparation method thereof. The concrete base wet-curing anticorrosive adhesive material is prepared from a high-polymer epoxy resin, a toughener, a mixed solvent, a pigment, an active filler and a curing agent. The preparation method comprises the following steps: dissolving the high-polymer epoxy resin in the mixed solvent to obtain a mixture, sequentially adding the toughener, pigment and active filler into the mixture, carrying out ball milling to obtain a mixed slurry, carrying out vacuum degassing on the mixed slurry, and removing impurities to obtain the concrete base wet-curing anticorrosive adhesive material. The concrete base wet-curing anticorrosive adhesive material has the advantages of favorable leveling property, no pinhole, high adhesive force and high acid / alkali / salt resistance, and can still be brushed when the surface humidity of the concrete base is up to higher than 85%; when the adhesive material is brushed, the concrete component does not need to be completely dry; on the wet concrete surface, the adhesive material can be coated immediately after removal of shuttering; the adhesive material can also be brushed immediately after the underground water is pumped off or in light rain; and thus, the adhesive material saves time and labor, shortens the construction period, and is especially suitable for the concrete base in need of anticorrosive treatment, which does not allow long-term drying due to the construction period or when the underground water can easily upsurge.

Description

technical field [0001] The invention relates to a concrete foundation moisture-curing anticorrosion adhesive material and a preparation method thereof, belonging to the field of concrete foundation anticorrosion. Background technique [0002] The concrete foundation has been buried underground for a long time. In the soil with high acid, alkali and salt content, the concrete foundation is severely corroded or even broken, which endangers the safe operation of power facilities. If ordinary materials are used for anticorrosion, but ordinary materials do not have moisture curing, it is necessary to wait for the inside and outside of the foundation to dry out before construction, resulting in prolonged construction time, and the construction period is generally very tight, and it takes a long time for the cast-in-place concrete foundation to dry out, especially It is a place where the groundwater is buried shallow, and it is easy to regurgitate after being drained, and the found...

AI Technical Summary

Problems solved by technology

If ordinary materials are used for anticorrosion, but ordinary materials do not have moisture curing, it is necessary to wait for the inside and outside of the foundation to dry out before construction, resulting in prolonged construction time, and the construction period is generally very tight, and it takes a long time for the cast-in-place concrete foundation to dry out, especially It is a place where the groundwater is buried shallow, and it is easy to regurgitate after being drained, and the foundation is difficult to dry

[0003] At present, the common main problems of anti-corrosion materials are: poor adhesion to the base material, inability to paint on the wet concrete foundation surface, poor acid, alkali, and salt resistance, low curing content, and large environmental pollution, etc.
