Description

technical field

[0001] The invention relates to an epoxy caulking agent, in particular to a solvent-free epoxy caulking agent and a preparation method thereof. Background technique

[0002] The caulking agent is used to fill the reserved gaps during the installation of ceramic tiles, stone materials, mosaics, etc., and to beautify the reserved seams of surface material decoration projects such as ceramic tiles, stone materials, and mosaics. Therefore, it has been widely used in residences, hotels, shopping malls, hospitals, factories and other occasions. Traditional sealants are generally white cement or cement-based sealants. This type of caulking agent has been widely used for many years due to its simple and easy-to-obtain raw materials, low cost, and easy use.
