Bi-component epoxy caulking agent and preparation method thereof

Abstract

Bi-component epoxy caulking agent comprises a component A and a component B and is characterized in that the component A comprises, by weight percent, 13.5-33.5% of waterborne epoxy resin, 25.5-68.5% of quartz sand, 0.5-2.5% of propylene glycol, 1-5% of glitter powder, 1-5% of propylene glycol leveling agent and 1-31% of talcum powder; and the component B comprises, by weight percent, 90-95% of waterborne epoxy hardener and 5-10% of phenol. The prepared component A and component B are packaged separately. The weight ratio of the component A to the component B is 10:1-4. The component A and the component B are mixed well according to a given proportion to obtain the bi-component caulking agent. The bi-component caulking agent has functions of caulking and decorating for mosaic or ceramic tiles. The bi-component caulking agent not only can be used as cement replacement for caulking the mosaic or ceramic tiles and the like, but is safe, efficient and free of side effects. The bi-component caulking agent is applicable to caulking and decorating of mosaic or ceramic tiles and the like.

Description

technical field [0001] The invention relates to a caulking agent, in particular to a two-component epoxy caulking agent and a preparation method thereof. Background technique [0002] With the rapid development of urban construction, various new building materials emerge in an endless stream. Similarly, the shapes and colors of mosaics and ceramic tiles are also changing with each passing day, and the application range of mosaics and ceramic tiles has been from toilets to kitchens, from interior walls to exterior walls, and And then extended to the walls of various other buildings.

Problems solved by technology

Then, in the process of mosaic or ceramic tile decoration on the wall, it is necessary to use cement to fill the joints, but the original expected effect is often not achieved after decoration.

This is due to the defects of cement, and after a period of cement decoration, fine lines or cracks are prone to appear, and the color of mosaics or tiles will turn yellow. Moreover, cement is easy to absorb moisture and seep water, and it will become moldy and mildewed over time. After that, bacteria will be produced, and the surrounding environment will be polluted. In addition, after using cement to operate, it is troublesome to clean the mosaic or tile surface. skin

In short, there are many unfavorable factors such as cement filling between mosaics or tiles and single color, that is, it needs to be further improved, so that the decorated mosaics or tiles can fully reflect its aesthetic effect.
