The main raw ingredients of most adhesives in the market are acrylic emulsion pressure-sensitive adhesive and glue (note: pressure-sensitive adhesive is the main ingredient for making transparent tape, which is characterized by strong early adhesion, low curing temperature and good temperature resistance, but poor oxidation resistance and aging resistance, and fear of water and ash). Most adhesives in the market need 2-3 hours of drying time (depending on ventilation, humidity and temperature) after painting before they can be put on the wall. Because equal drying is the process of water volatilization in the adhesive tape, water is the carrier to attach the adhesive tape to the back of the tile, and the water in the adhesive tape is exposed to the space and remains on the back of the tile after volatilization for a period of time, so the adhesive form of the adhesive tape after drying is very firm. Sticking is realized by using the principle of double-sided tape. After drying, cement mortar is stuck on the back of ceramic tile. This type of tape is a typical L-shaped tape in the market.
The Xubang T-800 liquid adhesive launched by Wuhan Tiancheng Xubang Company has made a major technological breakthrough. The main raw materials are acrylic emulsion and high molecular polymer, and one component can be pasted immediately after brushing to realize chemical bonding. This kind of glue has high solid content and does not need to wait for moisture to evaporate. When the adhesive is coated on the back of the ceramic tile, the cement mortar can be coated immediately, and the adhesive and the cement mortar can produce cross-linking reaction to realize bonding, thus enhancing the permeability and adhesion between the back of the ceramic tile coated with the adhesive and the cement sand.
Brush-paste is the development direction of adhesive. Many equal drying adhesives are close to brush paste, but most of them only reduce the moisture content and shorten the equal drying time, which is essentially equal drying.
