Safe, environment-friendly and nontoxic modified calcium carbonate and preparation method thereof
InactiveCN104031293ACause waste of resourcesImprove bindingPigment treatment with macromolecular organic compoundsFiberPolyphenol
The invention discloses a safe, environment-friendly and nontoxic modified calcium carbonate and a preparation method thereof. The modified calcium carbonate is prepared from the following raw materials in parts by weight: 90 to 95 parts of calcium carbonate, 2 to 3 parts of clam shell power, 2 to 3 parts of smashed yellow cinnamon leaves, 4 to 5 parts of alkenyl succinic anhydride, 2 to 3 parts of porous starch, 1 to 2 parts of sodium hyaluronate, 2 to 4 parts of easy-to-disperse fibers, 2 to 3 parts of urea, 4 to 6 parts of potash feldspar powder, 5 to 7 parts of high density polyethylene, 4 to 6 parts of nylon 66, 1 to 2 parts of tea polyphenol and 3 to 4 parts of modified titanium dioxide. The formula of the modified calcium carbonate is formed by adopting environment-friendly raw materials, so that the utilization of waste materials is realized, i.e., the waste of resources is avoided; a large quantity of safe and nontoxic components are added; the surface of the calcium carbonate is modified by utilizing the high-molecular polymers, so that the modified calcium carbonate has a high-molecular polymer layer. Thus, the bonding force of the modified calcium carbonate is enhanced while the performance of the modified calcium carbonate is not decreased. The modified calcium carbonate disclosed by the invention is applied to the production of preservative film aids, degradable plastics additives, pigment or paint additives and other functional products.

Preparation technology of modified calcium carbonate for plastic
The invention discloses a preparation technology of modified calcium carbonate for plastic. The modified calcium carbonate for the plastic is prepared from raw materials as follows: calcium carbonate, triethanolamine oleic soap, dicyclohexyl peroxydicarbonate, trimethylolpropanetris(3-aziridinylpropanoate), aluminum acetylacetonate, a catalyst, diethylenetriamine potassium pentacarboxylate, a modifier, di-iso-decylphthalate, hexenyl distearamide, 2-(2'-hydroxy-3',5-di-tert-phenyl)-5-benzotriazole chloride, N-ethyl-5-methyl-2-(1-methyl ethyl)cyclohexanecarboxamide and a stabilizer, and the modified calcium carbonate for the plastic is prepared through steps of surface modification, performance adjustment, crushing, drying and the like. The loose bulk density of modified calcium carbonate is significantly reduced, and modified calcium carbonate powder for the plastic is fully dispersed and has slight aggregation and good dispersity after being added to the plastic.
