Abstract

The invention discloses a paint in aqueous epoxy thick paste and a preparation method thereof, relating to the field of paints. The paint in aqueous epoxy thick paste disclosed by the invention adopts water as a dispersion medium and does not contain volatile organic solvents such as halogenated hydrocarbon, methylbenzene, dimethylbenzene and the like so as not to cause environmental pollutions and fire hazards so that the environmental protection requirement is met; modified polyamine is used as a curing agent so that the cross-linking density is improved and the thixotropy of the system is increased; and a silicone defoaming agent is added so that the problem of thick bubbles is solved and the sealing property of the system is good.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based epoxy mastic medium coating and a preparation method thereof. Background technique [0002] At present, in order to prevent the inner and outer walls of the wind power tower from being corroded or rusted, it is necessary to use three layers of paint on the inner and outer walls of the wind power tower for protection. [0003] At present, there are few water-based paints used for wind power towers. The bottom, middle and surface layers are generally made of paint, while the water-based epoxy high-build paint has never appeared in the mid-coat. Most of the anti-corrosion coatings for the inner and outer walls of wind power towers in my country are imported solvent-based coatings, which contain heavy metal compounds such as chromium or lead, which are highly toxic and will cause great harm to the environment and human health. Contents of the invention [0004] In order to im...
