Problems solved by technology
After optimizing the configuration method of water-based graphite paint and refining the application method, the quality of the paint has been more effectively controlled, the pass rate has reached 100%, and the paint consumption has also been reduced by 40%. However, some of today's water-based After the graphite coating is used once, due to the large molecular weight of the solute, the effect of gravity is greater than the force exerted by the water molecules, so that the solute deposition will often occur when the graphite coating is used next time. Must be stirred before use

The invention discloses water-based graphite paint and aims to solve the problem that traditional water-based graphite paint is prone to deposit. According to the technical scheme, the water-based graphite paint is characterized by comprising the following components in parts by mass as follows: 90-110 parts of graphite powder, 6-12 parts of clay, 2-3.5 parts of a tungsten-copper alloy, 1-3 parts of colloidal silicon dioxide and 2-5 parts of water. The water-based graphite paint is not prone to deposit.
Description
technical field [0001] The invention relates to the technical field of graphite coating processing, more specifically, it relates to a water-based graphite coating and a processing method thereof. Background technique [0002] Foundry coatings are used to coat the surface of molds or cores, and are an important means to improve the surface quality of castings. [0003] Coatings are usually composed of refractory powder, carrier liquid, binder, stable suspending agent and other additives. Among them, graphite has excellent refractory performance and is not infiltrated by liquid metal, while water is a good solvent and has polarity. , when used as a paint carrier, the water molecules have higher mobility due to the asymmetrical distribution of their electrons, so that after combining with the solute placed in the water body, they can be driven by greater mobility. The solute also moves, so that the solute can be better dissolved. Usually, water-based paint is a thixotropic c...
