Production method of alcohol-based concave-convex stick suspending agent

Abstract

The invention relates to a method for producing mellow concave-convex rod suspension. Wherein, it comprises mixing convex-concave rod clay, magnesia, sodium silicate, and macrogol, emerging, compressing, drying, grinding, and packing. The invention has low cost without using water in preparing casting coat, with suspension rate, non deposit, and high anti-adhesive property.

Description

Technical field:

[0001] The invention relates to a suspension agent, in particular to a production method of an alcohol-based attapulgite suspension agent. Background technique:

[0002] The casting coating made of alcohol-based suspending agent has the characteristics of fast drying, good combustibility and wide application range. It has begun to be used in the casting production of our country. At present, the problems of alcohol-based suspending agent are mainly manifested in dispersion, suspension and stability. Poor performance, the coating is prone to precipitation and agglomeration during long-term storage and transportation, followed by poor thixotropy, which affects the surface quality of the casting.

[0003] A good dispersing suspending agent can not only effectively ensure the uniformity of the dispersion of the coating components and the suspension effect of the coating, but also improve the brushability of the coating, which is beneficial to application and improves...
