Abstract

The invention relates to a magnesium olivine modified powder coating and a preparation method thereof. The magnesium olivine modified powder coating is prepared from the following raw materials in parts by weight: 2-16 parts of magnesium olivine powder, 10-32 parts of mullite powder, 10-26 parts of zircon powder, 15-30 parts of quartz powder, 3-5 parts of lithium-base bentonite powder, 1.5-3.5 parts of dextrin powder, 1-3 parts of white latex powder and 2-4 parts of carboxy methylcellulose powder; and the preparation method comprises the following steps of: evenly mixing the raw materials in proportion, and grinding for 2-3 hours, thus obtaining the magnesium olivine modified powder coating. As magnesium olivine is modified, the magnesium olivine modified powder coating is neutral at high temperature, thus being applicable to producing alkaline high-alloy steel, acidic low-alloy steel and iron castings; furthermore, the magnesium olivine modified powder coating can well prevent molten steel and molten iron from permeating since the solid phase self-sintering property of the magnesium olivine is well maintained; and when the castings are cleaned, the coating can be stripped off in pieces or blocks, so that the surface quality level of the castings can be improved.

Description

technical field [0001] The invention relates to a powder coating, in particular to a water-based powder coating composed of alkaline forsterite, mullite powder, zircon powder and other neutral materials and additives. Background technique [0002] Forsterite coating is weakly alkaline at high temperature. Although it has high refractoriness, no phase change, good resistance to sudden heat and cracking, it is only suitable for the production of alkaline high-alloy steel castings, and its application range is narrow. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a forsterite-modified powder coating and its preparation method, which is not only suitable for the production of alkaline high-alloy steel and iron castings, but also suitable for acidic and neutral low-alloy steel and iron castings Production. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the prese...
