Abstract

The invention provides a full-shape casting coating and a preparation method thereof, relating to the field of casting. The full-shape casting coating includes the following raw materials in parts by weight: quartz powder, olivine powder, corundum powder, sodium bentonite, lignin sulfonic acid, and dextrin powder , sodium carboxymethyl cellulose, sodium benzoate, hollow glass microspheres, aluminum sulfate, polyvinyl alcohol, silica sol, iron oxide powder, n-octanol, graphite powder, zircon powder, attapulgite, water reducing agent and water The preparation method comprises the following steps: (1) weighing raw materials, (2) preparing each mixed solution in turn, and (3) adding to a reaction kettle and stirring in turn. The invention solves the problem that the existing solid casting coatings generally have strong wear resistance, high adhesion, excellent air permeability and quick drying under high temperature and low temperature environments, which makes them unable to meet the production requirements of large castings. question.

Description

technical field [0001] The invention belongs to the field of casting, and in particular relates to a full mold casting paint and a preparation method thereof. Background technique [0002] The solid casting coating is a dispersion system composed of a variety of materials with different properties. Its composition mainly includes refractory materials, binders, carriers, suspending agents and special additives. It is required that the coating has good process performance, work performance and quality. Stability and application reproducibility. The solid casting paint is coated on the outer surface of the foam plastic model, and the molding can only be poured after the paint is dry. Foamed plastics are airtight, have a low heat distortion temperature (about 70°C), and have poor affinity for water; foamed plastics are heated and melted, and after gasification, there are many liquid residues and a large amount of gas generation. If these gases and liquid residues cannot be disc...
