Artificial stone glue, also known as marble glue, is an unsaturated polyester resin. It is suitable for bonding between various types of stones or repairing cracks on the surface of stone. It is often used in the repair and caulking of various types of stone paving projects. Marble glue in the stone industry has strong thixotropy, is smooth and delicate, does not have glue, and has a long rubber thread, which is very suitable for the production of cultural stone. And it has strong weather resistance, no yellowing, and strong cooking resistance.
Nowadays, the problem of artificial stone glue can be solved by mainly using ultrafine aluminum hydroxide micropowder as filler. The problems are as follows:
1. Aluminum hydroxide can be placed for one month without precipitation, which ensures the service cycle of the glue.
2. The refractive index of aluminum hydroxide and unsaturated resin is the same, the transparency is good, and there is no gap feeling.
3. The price of ultrafine aluminum hydroxide is relatively low compared with the price of raw materials such as silica, which greatly reduces the cost of raw materials.
To sum up, ultrafine aluminum hydroxide is the most suitable filling material for artificial stone glue.
