Carboxylated imidozoline phosphate activator for calcium carbonate

The invention discloses a carboxylated imidozoline phosphate activator for calcium carbonate. The carboxylated imidozoline phosphate activator for the calcium carbonate is prepared from, by weight, 5-8 parts of carboxylated imidozoline phosphate, 3-8 parts of pentaerythritol rosin resin, 25-30 parts of cocoanut fatty acid diethanolamide, 5-8 parts of sodium carbonate, 3-5 parts of poly(sodium acrylate-4-vinylpyridine), 5-6 parts of glycerol triacetate, 10-12 parts of dioctyltin oxide, 3-5 parts of polyvinyl acetal resin, 25-30 parts of gamma-glycidyloxypropyl trimethoxy silane, 3-5 parts of dodecyl dimethyl benzyl ammonium bromide, 20-30 parts of ethyl alcohol and 550-600 parts of water. The carboxylated imidozoline phosphate activator for the calcium carbonate has the advantages of scientific and reasonable design, technical simplicity, safety, reliability, easiness in control, convenience in operation, suitableness for large-scale production, low cost and the like.
