Abstract

The invention discloses a nano-crystal-whisker thixotropy thickening agent for a solvent-based coating and a preparation method thereof. The thickening agent is prepared from, by weight, 15-25 parts of halloysite slag, 14-22 parts of hectorite, 9-18 parts of cell quartz, 22-28 parts of dolomite, 10-15 parts of sepiolite, 17-23 parts of pseudo-boehmite, 12-18 parts of asbestos tailings, 6-12 parts of chalk powder, 10-15 parts of calcium silicon slag, 5-10 parts of magnesium trisilicate, 13-21 parts of ceramic waste, 4-7 parts of potassium acetate, 3-6 parts of anhydrous sodium sulphate, 5-10 parts of a modifying agent A and 10-15 parts of a modifying agent B. The prepared nano-crystal-whisker thixotropy thickening agent has the advantages of being high in thickening performance, good in thixotropy, good in stability and the like; a coating system can be endowed with excellent thixotropic performance, a leveling property and sagging resistance in the coating construction process are improved, spraying or batch scraping or rolling brushing can be carried out easily, the painting area is increased, opening time for the coating is prolonged, and film formation can be achieved easily.

Description

technical field [0001] The invention relates to a thickener and a preparation method thereof, in particular to a nano-whisker thixotropic thickener for solvent-based paints and a preparation method thereof. Background technique [0002] Thickeners are a class of coating additives that are widely used. Thickeners can thicken the paint to obtain excellent mechanical and physical and chemical stability, and play a role in controlling rheology during paint construction. At present, there are many types of thickeners used for coatings in the market, but most of them have the disadvantage of poor thixotropy, which can easily lead to the sedimentation and stratification of pigments and fillers in the coating system, which will affect the production, storage, construction and film-forming process of coatings. Therefore, it is very important to improve the thixotropy of the thickener. Contents of the invention [0003] The object of the present invention is to provide a nano-whis...
