Abstract

The invention discloses modified attapulgite packing for a coating. The modified attapulgite packing for the coating is prepared from the following raw materials in parts by weight: 1-2 parts of a titanate coupling agent, 3-5 parts of polyacrylamide, 2-3 parts of cellulose acetate butyrate, 4-5 parts of ethylene glycol, 1-2 parts of dimethylformamide, 2-3 parts of nanometer aluminium oxide, 1-2 parts of diethyl aminoethyl(methyl) acrylate, 1-2 parts of methacrylate, 0.2-0.4 parts of ammonium persulfate, 100-120 parts of attapulgite, a proper amount of water, 5-10 parts of an assistant, and 30-40 parts of 3-5% hydrochloric acid solution. According to the modified attapulgite disclosed by the invention, by high molecular polymeric modification, the surface lipophilicity is enhanced, the suspension property and the thixotropy of the coating are increased, and the modified attapulgite packing is good in thickening property, relatively full in film, and relatively good in can opening effect; by using the modified attapulgite packing, the wear-resisting property of the coating can be increased by addition of the nano aluminium oxide, the flowability of a powder coating can be improved, and the coating ratio is increased.

Description

technical field [0001] The invention belongs to the field of attapulgite processing, in particular to a modified attapulgite filler for paint and a preparation method thereof. Background technique [0002] Attapulgite has good colloidal properties such as unique dispersion, high temperature resistance, salt and alkali resistance, and high adsorption and decolorization ability. It also has certain plasticity and cohesive force, strong water absorption, stickiness and plasticity when wet, small shrinkage after drying, no obvious cracks, soaking in water and disintegration, and suspension does not flocculate and precipitate when it encounters dielectrics. Therefore, attapulgite is widely used in many fields such as sewage treatment, adsorption purification, detergent, rubber, paint, papermaking, light industry, agriculture, cosmetics, etc. It is an important non-metallic mineral. [0003] In order to further improve the use effect of attapulgite and enhance its overall physica...
