Problems solved by technology

Ordinary casting alcohol-based coatings are usually ignited to dry and dehumidify and promote the hardening of the coating. However, it is impossible to directly identify whether it is completely dry after burning, and it is also impossible to directly determine whether the dried coating absorbs moisture after being placed for a period of ti...

Abstract

The invention discloses and provides alcohol group casting coating with a dry-wet indication function and a sintering peeling function and a production process of the alcohol group casting coating. The fireproofing material of the coating comprises the following materials by weight: 40-50% of mullite powder, 30-40% of high bauxite powder, 20-30% of quartz sand powder; and the fireproof material comprises other materials by weight: suspending agent: 1-3% of hectorite powders and 1-3% of palygorskite powders; 5-10% of agglutinant; binding agent: 1-2% of thermoplastic phenol resins and 0.5-1.5% of rosins; 0.1-0.5% of bromocresol green indicator, 30-40% of industrial alcohol; and 10-20% of isopropyl alcohol. The production process of the alcohol group casting coating with the dry-wet indication function and the sintering peeling function is simple and convenient to operate; and the raw materials are abundant and the production cost is low. The alcohol group casting coating with the dry-wet indication function and the sintering peeling function and the production process of the alcohol group casting coating are suitable for the technical field of casting materials.

Description

technical field [0001] The invention relates to an alcohol-based casting coating with both dry and wet indicating functions and sintering peeling functions and a production process thereof. Background technique [0002] In foundry production, sand casting accounts for about 70% of the total castings, and sand casting coatings can significantly improve the surface finish of castings and prevent castings from sticking to sand, so they are widely used. [0003] At present, the coatings used in sand casting are still based on alcohol-based coatings. The advantages of alcohol-based casting coatings are: 1. Good coating strength can be formed by brushing and igniting; 2. Easy to use and short production cycle. Ordinary casting alcohol-based coatings are usually ignited to dry and dehumidify and promote the hardening of the coating. However, it is impossible to directly identify whether it is completely dry after burning, and it is also impossible to directly determine whether the...
