Abstract

The invention provides a casting paint composition prepared by industrial dust. The casting paint composition comprises the components of the industrial dust, carrier liquid, silicon carbide, alkali phenolic resin, amphiphilic cellulose ether, attapulgite, porcelainizing agent, calcium phosphate, sodium fluosilicate, polycarboxylate and acetylenic diol; and the mass parts of the components are asfollows: 100 parts of industrial dust, 40-70 parts of carrier liquid, 5-15 parts of silicon carbide, 5-15 parts of alkali phenolic resin, 0.2-0.6 part of amphiphilic cellulose ether, 2-10 parts of attapulgite, 4-12 parts of porcelainizing agent, 2-6 parts of calcium phosphate, 3-7 parts of sodium fluosilicate, 0.2-0.6 part of polycarboxylate and 0.1-0.3 part of acetylenic diol. Casting paint is prepared by fully using effective components of casting resin sand regenerative dust and thinner strength characteristic; the prepared casting paint is excellent in performances, and can meet the requirements of the casting paint; meanwhile, the recycling of the industrial dust is achieved; the environmental pollution is reduced; the production cost is reduced; and the comprehensive and cyclic utilization of resources is achieved.

Description

technical field [0001] The invention relates to the technical field of casting coatings, in particular to a casting coating composition prepared from industrial dust. Background technique [0002] A large amount of industrial dust will be produced in the process of industrial production. For example, in the foundry industry, the industrial dust produced includes modeling resin sand ash, recycled resin sand ash, shot blasting ash, casting ash, porcelain pipe cutting ash, etc. In the existing In technology, most of these dusts cannot be used directly and are directly discharged for treatment. This will cause waste of available resources on the one hand, and pollute the environment on the other hand. [0003] After searching, it is found that in the patent document with the notification number CN106890931A, a casting coating prepared by casting resin sand reclaimed dust is disclosed, which makes full use of the active ingredients and finer strength characteristics of foundry re...
