Performance and Application Effect of Aluminate Coupling Agent

Aluminum ester coupling agent is an essential raw material in the rubber and plastic industry and coating production field in China. It not only has stable quality, but also has good synergistic stability and lubricity.

Due to the activation and modification of fillers by aluminum ester coupling agents, fundamental changes will occur on their surfaces. It has the functions of reducing water absorption, reducing particle diameter, lowering oil absorption, improving physical indicators of composite materials, and reducing production costs. In addition, aluminum ester coupling agents have a low melting point and do not require diluents, making them very convenient for practical use.

When using, first heat the filler in a high-speed kneading machine to 105 degrees Celsius&-110 ℃, then stir and dry to remove moisture, so that the moisture content of the filler is below 0.3%. Then cut the coupling agent into small pieces and add them in three separate times, with an interval of 2 between each time&About 3 minutes. At this point, adding 0.5% stearic acid can enhance the synergistic effect of the aluminum ester coupling agent. It should be noted that fillers and preparations should not be added in advance or simultaneously to avoid reducing the effectiveness of use.
