Problems solved by technology

[0002] In the patent search of the prior art, it was found that casting coatings with high-alumina refractory materials as aggregates are generally made of one or several different refractory materials, and for the particle distribution of each type of aggregate, it is often selected A particle size specification that is not very specific
[0003] However, most of the aggregates in the traditional alcohol-based coatings for high-quality cast steel use zircon powder. While obtaining high quality, a large amount of zircon powder also brings high material costs.

Abstract

The invention discloses high-concentration alcohol-based paint used in cast steel. The paint comprises 66-75% of refractory aggregates, 0.5-1.5% of a binder, 1.0-2.5% of a suspending agent, and 21-30% of isopropanol, wherein the refractory aggregates comprise 50-70% of white corundum, 20-40% of brown corundum, and 10-30% of mullite. The particle size distribution of the refractory aggregates is that: particles with diameters lower than 38mum accounts for 10-20%, particles with diameters of 38-53mum accounts for 40-60%, particles with diameters of 53-75mum accounts for 30-50%, and particles with diameters higher than 75mum accounts for 0-10%. According to the invention, the refractory aggregates with lower cost are intelligently selected for replacing a zircon powder aggregate, and characteristics of high refractory degree and surface fusion property are obtained as well. Also, the paint has large softening temperature zone. Through reasonable particle size selection and specific binder optimization, aggregate content is higher than 75%, such that excellent performance is obtained.

Description

technical field [0001] The invention relates to a casting coating, in particular to an alcohol-based alcohol-based coating for casting. Background technique [0002] In the patent search of the prior art, it was found that casting coatings with high-alumina refractory materials as aggregates are generally made of one or several different refractory materials, and for the particle distribution of each type of aggregate, it is often selected A particle size specification that is not very specific. [0003] Zircon powder is mostly used as the aggregate in traditional alcohol-based coatings for high-quality cast steel. While obtaining high quality, a large amount of zircon powder also brings high material costs. Contents of the invention [0004] The technical problem to be solved by the invention is to provide a low-cost high-density high-quality alcohol-based coating for casting. [0005] In order to solve the problems of the technologies described above, the technical sol...
