Problems solved by technology

[0002] The commonly used silicon steel sheet paint, especially the silicon steel sheet paint used on large generator silicon steel sheet, is organosilicon steel sheet paint. Because organic silicon steel sheet paint contains organic solvent, it is very volatile at high temperature, so it is not resistant to high temperature and is easy to cause environmental pollution. , and the coating is thick, the drying temperature is high, and energy is wasted. In addition, the coating shrinkage coefficient is large, which is prone to carbonization problems

Abstract

The invention provides a water soluble semi-inorganic silicon-steel plate paint and a preparation method thereof. The prior silicon-steel plate paint, particularly the silicon-steel plate paint used in a silicon-steel plate of a large generator, is organic silicon-steel plate paint. Containing organic solvents which can be easily volatilized at high temperature, the organic silicon-steel plate paint cannot resist high temperature, easily pollute environment; due to thick coating, the organic silicon-steel plate paint requires high drying temperature and causes energy waste; and furthermore, the coating with a large coefficient of thermal compression contraction easily gives rise to the problem of carbonization. The water soluble semi-inorganic silicon-steel plate paint comprises paint, inorganic filling, a dispersing agent and water, and is characterized in that the weight portion ratio of the paint to the inorganic filling to the dispersing agent to the water is 85 to 36 to 65 to 15.The water soluble semi-inorganic silicon-steel plate paint can be used in the silicon-steel plates of large generators.

Description

Technical field: [0001] The invention relates to a water-soluble semi-inorganic silicon steel sheet paint applied to large generator silicon steel sheets and a preparation method thereof. Background technique: [0002] The commonly used silicon steel sheet paint, especially the silicon steel sheet paint used on large generator silicon steel sheet, is organosilicon steel sheet paint. Because organic silicon steel sheet paint contains organic solvent, it is very volatile at high temperature, so it is not resistant to high temperature and is easy to cause environmental pollution. , and the coating is thick, the drying temperature is high, and energy is wasted. In addition, the coating shrinkage coefficient is large, which is prone to carbonization. Invention content: [0003] The purpose of the present invention is to provide a kind of water-soluble semi-solid coating with thin coating, low drying temperature, energy saving, not easy to carbonization, good high temperature re...
