Abstract

The invention discloses a casting alcohol-based coating which comprises, by weight, 10-25 parts of a refractory aggregate, 50-60 parts of a carrier, 2-7 parts of a binder, 10-15 parts of a suspensionagent, and 8-49 parts of additives. The casting alcohol-based coating has high viscosity, brush-ability, anti-sagging effect, leveling effect, permeability, suspensibility, coatability and thixotropy.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a casting alcohol-based coating. Background technique [0002] Alcohol-based coatings have been widely used in my country because of their advantages such as fast drying speed, high production efficiency, low cost, short production cycle, and wide application range. The annual consumption can reach 30,000 to 40,000 tons, and its usage is showing an increasing trend, and the market prospect is broad. However, there are many problems in the use of alcohol-based coatings produced by my country, such as poor suspension, poor advection, volatile, refractory aggregate sinking to form "dead sediment" and so on. Therefore, the research on alcohol-based coatings for casting has become one of the urgent problems to be solved. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a casting alcohol-based coating with excellent viscosity,...
