Abstract

The invention relates to a double-component polyurea sealant. The double-component polyurea sealant comprises a component A and a component B. The component A comprises polyaspartic acid ester polyurea, fumed silica, lime powder, a leveling agent, a dispersing agent, an accelerant and matte powder. The component B comprises curing agent isocyanate, epoxy resin, a defoaming agent, a wetting agent and pigment. The invention has the following beneficial effects: the sealant is formed by compounding polyaspartic acid ester polyurea, a curing agent isocyanate, epoxy resin and a plurality of reinforcing agents, has strong yellowing resistance, reduces heated volatilization deformation, is firm in connection, strong in adhesive force, water-resistant and high in adhesive force, and is not easily influenced by construction conditions.

Description

technical field [0001] The invention belongs to the technical field of decoration materials and relates to a two-component polyurea beautifying agent. Background technique [0002] Beautifying agent is an upgraded product of jointing agent. The gap position of modern household tiles and marble materials will usually change from white to black due to the influence of smoke, dust and oil as the use time increases. If it is not treated for a long time, it will not only affect the appearance, but also It is easy to breed mold, produce peculiar smell, and then affect the home environment. It is a common problem that plagues the decoration industry and family health. Beautifying agent is an upgraded product of traditional white cement and caulking agent. It is mainly used in the joints of tiles or stones to solve the problems of unsightly joints, dirty black, and graying of tiles or stones. [0003] Existing beautifying agents are generally divided into one-component beautifying ...
