Alcohol-based paint for cast steel and method for preparing and using same

Abstract

The invention discloses a cast steel alcohol-based paint, as well as a preparation and application method thereof. The cast steel alcohol-based paint comprises the following components: 12-18 wt% of ethyl alcohol, 4.5-8 wt% of isopropanol, 0.4-2.5 wt% of black rosin, 0.35-3 wt% of solvent naphtha, 0.9-2.5 wt% of aluminium-magnesium silicate, 0.5-2.6 wt% of phenolic resin, 0.05-0.5 wt% of poval, 0.1-1 wt% of white carbon black, 0.15-2.5 wt% of attapulgite, 40-60 wt% of zircon powder, 10-25 wt% of fused alumina zirconia powder, 0.1-0.5 wt% of kunzite, 0.8-2.5 wt% of ludox and 0.5-3.5 wt% of pyrophyllite powder. The specific preparation and application method are shown in the specification. The cast steel alcohol-based paint has the following benefits: the refractoriness is high, sintering is easy, and the sand burning resistance is good; in addition, the solid content is high, the suspension property is good, the gas content is low and excellent thixotropic property is realized; moreover, after a coating is hardened, the strength is high, and the hygroscopicity resistance is good.

Description

technical field [0001] The invention relates to casting coatings, in particular to an alcohol-based coating for casting steel and its preparation and application method. Background technique [0002] China is a big foundry country. Cast steel coating is the most important casting auxiliary material related to the quality of castings. However, the level of domestic cast steel coating is far behind that of foreign countries. Due to the high pouring temperature of cast steel (up to 1750 degrees), it is difficult for casting The requirements for coatings are quite high. The overall level of domestic cast steel coatings is relatively low, and the aggregates with high melting points are blindly pursued. However, the indicators such as sinterability, suspension, and brushability cannot compare with foreign coatings. Monopolized by several foreign brands, such as Foseco, Ashland and so on. [0003] The invention aims at improving the performance of various aspects of the cast steel...
