Method for preparing polycarboxylate-type ceramic dispersant by use of normal temperature method
The invention provides a method for preparing a polycarboxylate-type ceramic dispersant by use of a normal temperature method. The method comprises the steps of (1) dissolving 5-15 moles of chain transfer agent t, 0.5-1.5 moles of reducing agent H, 10-20 moles of monomers A and 5-25 moles of monomers B in an appropriate amount of water in a reactor, (2) adding 80-90 moles of monomers A and 4-10 moles of initiator to an appropriate amount of water to form a solution and dropwise adding the solution to the reactor, and (3) dropwise adding an alkaline solution to the reactor until the pH of the solution in the reactor is within the range of 8-10, thereby obtaining the polycarboxylate-type ceramic dispersant. The method has the beneficial effects that few by-products are generated, the preparation method is simple and controllable, the preparation process is safe, environmental friendly, clean and pollution-free, and suitable for industrial production, and the polycarboxylate-type ceramic dispersant is widely applicable to ceramic powders, good in grinding adding effect and high in water reducing ratio.
