Abstract

The invention discloses a building curtain wall joint mixture. A base material is prepared by smashing white Portland cement and white Portland cement into 300-500 meshes, adding glass beads, hydroxypropyl methyl cellulose, an inorganic aluminium salt waterproof agent and aluminium-magnesium silicate, and conducting even stirring. The auxiliary materials are prepared by mixing and evenly stirring ethylene-vinyl acetate copolymers, acrylic resin, fumed silica, RTV organic silica gel, lignin fiber and brightener. Iron oxide pigment is selected according to the color classification of the joint mixture, the base material is added to a high-speed shearing and stirring machine, the auxiliary materials and the iron oxide pigment are sequentially added in the shearing and stirring state, the shearing speed ranges from 6000 RPM to 8000 RPM, the shearing time ranges from 45 min to 90 min, and the joint mixture is obtained after stirring and discharging. The joint space is cleaned, primary water is sprayed on the joint seam to wet the joint seam, the joint mixture and water are mixed into a thick material according to the mass ratio of 1 to 0.4-0.6, the space between tiles is filled with the thick material, primary water is sprayed again after drying, and natural drying is conducted.

Description

technical field [0001] The invention relates to a construction joint filler, in particular to a building curtain wall joint sealant, a preparation method and a use method. Background technique [0002] Because the caulking agent can perfectly repair the cracks or damages on the ground surface, and it can also be prepared in rich colors, it is more and more popular among customers. However, most of the existing joint fillers are made of cement, together with additives commonly used in cement, which have the disadvantages of environmental resistance and environmental protection, and have great limitations in application occasions, safe use, and long life. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a joint filler for building curtain walls, a preparation method and a use method. [0004] The technical solution adopted in the present invention is: a building curtain wall sealant, comprising 40-50 parts of white Portl...
