PREPARATION METHOD OF SYNTHETIC FLOWABILITY CONTROLLING AGENT

摘要

PURPOSE: A method for a synthetic flowability controlling agent is provided, to improve the repairing property of the agent in used in coating solution and the adhesion of the agent to coating paper. CONSTITUTION: The method comprises the steps of: reacting 10-20 parts by weight of acrylate containing at least one unsaturated group, 0.1-5.0 parts by weight of an emulsifying agent and 0.1-5.0 parts by weight of an initiator at 60-80°C for 1-3 hours to obtain the initial polymer; and adding 5 parts by weight of urea or less, 0.1-5.0 parts by weight of parts by weight of an initiator, 40-80 parts by weight of acrylate containing at least one unsaturated group, and 10-40 parts by weight of acrylic acid containing at least one unsaturated group to the initial polymer, and proliferation polymerizing them at 70-90°C for 2-4 hours. Preferably the acrylate containing at least one unsaturated group is selected from butyl methacrylate, ethyl acrylate and methyl methacrylate.
