Abstract

The invention discloses a preparation method of a novel casting coating, and relates to the field of casting coatings. The coating comprises the following raw materials of 20-30 parts of graphite, 25-35 parts of forsterite, 5-10 parts of bentonite, 20-40 parts of a filler, 3-5 parts of an antifoaming agent, 2-5 parts of quartz sand and 20-30 parts of water. According to the method, due to the factthat the use amount of the forsterite is increased, so that the proportion of the graphite in the coating is reduced, the adhesive force between the coating and the surface of a mold is reduced, cleaning is easy, and the possibility that the graphite generates pores is greatly reduced; and meanwhile, due to the fact that the forsterite is rich in source and low in price, so that the reduction ofthe production cost is facilitated.

Description

technical field [0001] The invention relates to the field of casting coatings, in particular to a method for making a novel casting coating. Background technique [0002] Casting Coatings: Casting products need to be cast into metal molds after melting, and then the products are separated from the molds (demoulding). In order to release the mold, it is necessary to spray a layer of liquid containing refractory material on the mold in advance, i.e. coating. [0003] Coating composition: Coatings used in foundry production are mainly composed of refractory materials, dispersion media, binders and suspending agents. Among them, the real role is the refractory material. Different refractory components will have different effects on the quality of cast products. So the composition of the paint is very critical. [0004] The coating currently used is easy to adhere to the mold, difficult to dry, and difficult to clean, resulting in easy generation of pores and slag inclusions ...
