Problems solved by technology

In the prior art, casting coatings tend to focus on satisfying the coating properties of the actual use process, often ignoring other performances that need to be met. For example, the Chinese patent titled "A Casting Coating" with application number 201410740217.6, the scheme is disclosed developed a foundry coating comprising raw sand, binders, curing agents and lubricants, which can also be used for foundry, however in this proposal not much attention has been paid to the properties of the coating other than paintability

Abstract

The invention discloses an environment friendly casting coating as well as a preparation method and a using method thereof. The environment friendly casting coating comprises the followings in parts by mass: 100-120 parts of a component A, 130-150 parts of a component B and 15-25 parts of a component C, wherein the component A is fireproof material; the component B is carrier liquid and a binder; and the component C is an additive and an assistant. The environment friendly casting coating has the advantages of excellent thermal insulation property, high strength, low gas evolution amount and excellent rheological property and suspendability, is environment friendly and non-poisonous, does not generate toxic and harmful substances during the manufacturing and using processes, and can well protect operators and atmospheric environment in the casting flow.

Description

technical field [0001] The invention belongs to the field of casting, and in particular relates to an environment-friendly casting coating, a preparation method and a use method thereof. Background technique [0002] Lost foam casting technology is a precision molding technology that has been widely used at home and abroad. Coating is one of the key technologies of the lost foam casting process, and the quality of the coating directly affects the success or failure of the process. Many literatures disclose that the success of the lost foam casting process depends on the shape 50%, 30% on the coating, and 20% on other process factors. Pay attention to. In my country, due to the low degree of commercialization of casting coatings, most lost foam casting manufacturers lack systematic and in-depth research on the formulation and performance of coatings. In actual production, they are generally prepared for their own use at the production site, resulting in many casting quality...
