| titleOfInvention | Composition for making antistick coatings |
| abstract | FIELD OF THE INVENTION The invention relates to the field of foundry, in particular, compositions for producing nonstick coatings of casting molds and cores. The purpose of the invention is to improve the quality of the coating by increasing the sedimentation stability of the composition. The invention relates to a foundry, in particular, compositions for producing nonstick coatings for casting molds and cores. The purpose of the invention is to improve the quality of the coating by increasing the sedimentation stability of the composition and its vitality. As a refractory filler, the composition may contain: powdered quartz (marshalite), defrosted zircon, graphite or talc. Formula and its survivability. The composition contains the following ingredients, wt%: refractory filler 45.0 - 50, Oj molding clay 2.0-3.0; sulfite alcohol bard 2.0-3.0; VAT residue of polyvinylpyrrolidone production by organic synthesis is 0 / 5-0.7, water is the rest. To obtain the coating ingredient is pre-mixed for 5-10 minutes. In the process of mixing, the residue of the residue forms a structured system with the sulfite barda, which provides the structural viscosity of system No. 1, as a result of which the filler (zircon, talc, graphite, morsalite) does not settle. The composition exhibits the best crown abilities with a ratio of sulphite bards and vat residue from 3: 1 to 4: 3. The presence of oxybutyric acid in the bottom residue of the amide gives the composition antiseptic properties. When using the composition according to the invention, the castings did not have a burn. 2 tab. Secondary clay is used as a stabilizing additive, and sulfite-alcohol bard is used as a binder. To increase the sedimentation stability of the composition, a cubic residue of polyvinylpyrrolidone production by organic synthesis is used. It is a waste product and is a non-toxic, fireproof liquid with a density of 1150 tons / m, nominal VZ-4 viscosity of at least 30 s and more (L with 4 05 cx about 4 |
