Application of Superfine Aluminum Hydroxide Powder in Artificial Stone Glue
Artificial stone glue, also known as marble glue, is a kind of unsaturated polyester resin, suitable for bonding between various types of stone or repairing cracks on the surface of the stone. It is often used for repairing and caulking various types of stone paving projects. . The marble glue in the stone industry is thixotropic, smooth and delicate, without glue, and the glue line drawn is long, which is very suitable for the production of cultural stones. Moreover, it has strong weather resistance, no yellowing, and strong boiling resistance.
Nowadays, the problem of artificial stone glue can be solved by mainly using ultrafine aluminum hydroxide powder as a filler. The problems are as follows:
1. The aluminum hydroxide can be placed for one month without precipitation, which ensures the life of the glue.
2. The refractive index of aluminum hydroxide is the same as that of unsaturated resin, with good transparency and no gap.
3. The price of ultra-fine aluminum hydroxide is lower than that of raw materials such as white carbon black, which greatly reduces the cost of raw materials.
In summary, ultrafine aluminum hydroxide is the most suitable filler material for artificial stone glue.
