Abstract

The invention provides an epoxy color sand sealant and a preparation method thereof. The epoxy color sand sealant is prepared from a component A and a component B, wherein the component A is preparedfrom the following components in parts by weight: 40 to 60 parts of water-based hydroxyl epoxy resin, 8 to 15 parts of a water-based photocuring carboxylated polyurethane dispersoid, 1.5 to 5 parts offumed silica, 30 to 50 parts of color glass micro beads, 0.5 to 2 parts of a silane coupling agent, 5 to 10 parts of graphene oxide, 4 to 6 parts of modified polysiloxane and 3 to 6 parts of nano zinc oxide; the component B is prepared from the following components in parts by weight: 20 to 40 parts of a water-based epoxy curing agent, 2 to 3 parts of fumed silica, 20 to 30 parts of color glass micro beads, 20 to 25 parts of glitter powder and 0.5 to 1.5 parts of a rheological agent; a mass ratio of the component A to the component B is 1: (1 to 1.5). According to the epoxy color sand sealantand the preparation method thereof which are provided by the invention, the surface of a cured adhesive film is excellent in mechanical intensity and hardness, and the scratching resistance and the wear resistance are enhanced.

Description

technical field [0001] The invention relates to the technical field of beautifying agents, in particular to an epoxy colored sand beautifying agent and a preparation method thereof. Background technique [0002] With the rapid development of the decoration field, people have higher and higher requirements for the beauty of home decoration. Usually, ceramic tiles, mosaics or stones are used as wall and floor decorations. However, tiles, mosaics or stones need to be collaged between each piece to form gaps when laying, and these gaps need to be filled with a caulking agent. At present, the commonly used caulking agent is generally white cement, which is easily polluted by dust, oily smoke, etc. and turns black, and is also prone to mold and odor. For this reason, there is now a beautifying agent as an improved product of the caulking agent. The beautifying agent is mainly composed of water-based polymer emulsion and pigments and fillers. It is highly decorative, but the cured...
