Abstract

The invention provides a liquid-state potassium-zinc promoted foaming agent and a preparation method thereof. The preparation method comprises the following steps: A. adding acid liquor in a reaction kettle, covering the reaction kettle with a reaction kettle cover, stirring and heating to the temperature of 65-70 DEG C; B. slowing adding potassium hydroxide which is dissolved with water, and after 10-20min, adding zinc oxide and a water carrying agent; and C. controlling the temperature in the reaction kettle to the constant temperature of 90-95 DEG C, then adding a saturated cycloalkane solvent, and finishing the reaction to prepare the liquid-state potassium-zinc promoted foaming agent. By simplifying the process, scientifically controlling the sequence and temperature in the reaction of all raw materials and the like, the invention can produce the products in a short time under the condition of environment production.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to a liquid potassium-zinc foaming accelerator and a preparation method thereof. Background technique [0002] Industrial micro-foaming products mainly include wallpaper, non-slip mats, and yoga mats. In the synthesis process of these PVC foamed artificial leathers, a PVC liquid foaming heat stabilizer with both thermal stability and foaming effect is generally used. The characteristic of the liquid foaming heat stabilizer is that it can be combined with azodicarbonamide, i.e., the AC foaming agent after heating, so that the property of the AC foaming agent is more unstable, and it is easy to decompose at 150-180 ° C, resulting in Plenty of air bubbles to finish the craft product at the end. The liquid prompts the foaming heat stabilizer to react with azodicarbonamide to generate a metal salt of azodicarboxylate or a compound containing cadmium, tin, and lead that is more unstable and...
