Water-based zircon powder quick drying paint for ultra-large steel casting

Abstract

The invention discloses a water-based zircon powder quick drying paint for an ultra-large steel casting. The paint consists of refractory material, binder, suspending agent and water, wherein the refractory material is zircon powder; the paint also contains high-purity magnesium oxide, the MgO content of which is more than 99 percent; and the paint comprises the following components in percentage by weight: 70 to 83 percent of zircon powder, 2 to 3.5 percent of binder, 1 to 2.5 percent of suspending agent, 0.1 to 0.5 percent of high-purity magnesium oxide and the balance of water, wherein the binder is vinyl acetate / acrylic emulsion and the suspending agent is lithium-based bentonite. The paint can effectively promote moisture migration on the surface of the paint by adding a reasonable amount of magnesium oxide aid so that the paint can quicken the curing speed, the next coating of the paint can be performed without drying the paint in short time, the production process is simplified, the resource is saved and the energy consumption is reduced.

Description

technical field [0001] The invention relates to a casting coating, in particular to a coating suitable for large castings. Background technique [0002] Alcohol-based coatings are often used in the production process of existing super-large steel castings, but the safety of alcohol-based coatings is not enough, and accidents are prone to occur. [0003] The water-based coatings used for super-large steel castings are safer than alcohol-based coatings, but the curing speed is slower. Each coating must be dried separately before the second coating can be applied, which greatly increases the production process. and energy waste, prolonging the production cycle. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a water-based paint with quick-drying function. After the paint is painted, it does not need to be dried in a short period of time. The surface has a certain strength and can continue to be coated with a second...
