Problems solved by technology

However, pulverized coal also has insurmountable shortcomings such as polluting the environment, deteriorating working conditions, and affecting human health.
Someone has analyzed the pulverized coal and found that after the pulverized coal is burned, it can produce 6% of sulfur dioxide, 0.3-0.9% of carbon dioxide, 0.2% of carbon monoxide and other substances. In addition, about 10% of ash can be accumulated in the molding sand, making the The performance of molding sand deteriorates, which affects the service life and recycling rate of molding sand
People have used heavy oil, asphalt, coal tar, etc. to replace this, but they are not ideal

Abstract

The invention discloses a brightener for casting, and belongs to the technical field of casting. The brightener is specifically prepared from modified palygorskite powder, isostatic polypropylene, polyvinyl chloride, ground calcium carbonate, sodium dodecyl benzene sulfonate, sodium carboxymethylcellulose, benzyl phenol polyoxyethylene ether, laurinol polyoxyethylene ether, polyoxyethylene stearate, rare earth nitrate, aluminum stearate and deionized water. The prepared brightener can well improve the softness, fluidity, toughness and high-temperature impact resistance of casting sand, the phenomena of sand burning, peeling and sand inclusion in the casting process are remarkably reduced, surface brightness of a casting is guaranteed, no ash is generated, the service life of the casting sand is prolonged, and the repeated utilization rate of the casting sand is increased.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a brightener for casting. Background technique [0002] Coal powder is the most widely used and most common casting anti-sand sticking material for wet mold molding in foundries. It has the advantages of wide source, low cost, good anti-sand sticking performance, and can prevent sand inclusions and subcutaneous pores. However, pulverized coal also has insurmountable shortcomings such as polluting the environment, deteriorating working conditions, and affecting human health. Someone has analyzed the pulverized coal and found that after the pulverized coal is burned, it can produce 6% of sulfur dioxide, 0.3-0.9% of carbon dioxide, 0.2% of carbon monoxide and other substances. In addition, about 10% of ash can be accumulated in the molding sand, making the The performance of molding sand deteriorates, which affects the service life and recycling rate of molding sand. P...
