Abstract

The invention relates to the technical field of casting materials, in particular to a novel light-colored casting material. The novel light-colored casting material is prepared from, by mass part, 15-19 parts of crystalline flake graphite powder, 20-30 parts of iron sesquioxide, 5-12 parts of divinyl polyamine, 10-20 parts of zircon powder, 21-32 parts of brown aluminium oxide powder, 25-35 parts of bauxite powder, 15-20 parts of bentonite, 4-9 parts of talcum powder, 1.8-3.2 parts of calcium stearate and 4.8-6.5 parts of polyvinyl butyral. After the formula is adopted, the surface quality of an iron casting cast through the light-colored casting material is obviously superior to that of traditional black graphite paint, and the work environment is powerfully improved. In addition, the novel light-colored casting material is low in ingredient cost and convenient to apply and popularize.

Description

technical field [0001] The invention relates to the technical field of casting materials, in particular to a novel light-colored casting material. Background technique [0002] Casting materials are commonly used modeling materials to prevent defects such as sand sticking and sand inclusions on the surface of castings, reduce the surface roughness of castings, and reduce the workload of cleaning the surface of castings. They have various technical effects and good comprehensive economic benefits. At present, ordinary cast iron coatings in China generally use microcrystalline graphite powder and flake graphite powder as basic refractory materials. Graphite powder has high refractoriness and low price, which can effectively prevent sand sticking defects caused by metal penetration. However, the graphite powder coating is black, which seriously pollutes the working environment and worsens working conditions when it is prepared and used. Contents of the invention [0003] Th...
