The main applications of aluminum ester coupling agents and their effectiveness in treating inorganic fillers:
1. Applied in the plastic industry, fillers can be activated to increase filling volume, reduce resin usage, lower product costs, improve processing performance, increase product gloss, and improve quality.
2. When applied in the rubber industry, the filler modification can play a reinforcing role, reduce the amount of rubber and antioxidant, improve the wear resistance and anti-aging ability, and significantly improve the gloss.
3. Applied in the paint industry, it can increase the amount of pigments and fillers, improve dispersion performance, have anti settling effect, prevent flower formation, improve adhesion and paint film strength, have bright color, and also have drying properties. It can also reduce baking temperature and shorten baking time for baking paint.
4. Applied in the ink industry, it enables pigments to wet and disperse quickly, shortens grinding time, makes ink bright, has good adhesion, and stabilizes system viscosity without swelling.
5. Applied in the papermaking industry, it improves the dispersibility of calcium carbonate or talc powder, reduces loss and wear, enhances paper strength, and improves paper printing performance.
6. The application in the magnetic material industry significantly improves the dispersibility of magnetic powder, enhances its affinity with the base or carrier, thereby increasing its filling amount, increasing magnetic density, and significantly improving magnetic signal.
Application of Aluminate Coupling Agent:
1. Used to process fillers with high moisture content, such as wet process SiO2, wet process lightweight CaCO3, ultrafine fillers, etc.
2. Used to treat water-based coatings, improve dispersibility, prevent sedimentation, and enhance coloring power.
3. Used for magnetic materials to increase the density and dispersion of magnetic powder in the substrate, thereby improving the capacity and quality of magnetic recorders.
Treating inorganic fillers with aluminum esters can achieve the following effects:
1. Save energy consumption of raw materials;
2. Improve the dispersibility of pigments;
3. Improve the corrosion resistance of coatings;
4. Increase the filling amount of inorganic fillers;
5. Improve the flame resistance of composite materials;
6. Reduce the filling material— Viscosity of polymer systems;
7. Improve the machining process performance of the coordination system.
