Temperature indication coating material

Abstract

The present invention provides a temperature indication coating material, which comprises the following components, by weight, 25-30 parts of lead stearate, 20-25 parts of arachidic acid, 1-2 parts of methyl cellulose, 1-2 parts of ethyl cellulose, 20-30 parts of xylene, and 15-20 parts of n-butyl alcohol. The temperature indication coating material of the present invention has the following technical effect that: when the coating layer is heated to a certain temperature, a color is changed or other phenomena are changed to indicate the temperature and the temperature distribution on the surface of the object.

Description

[0001] Technical field [0002] The present invention involves a kind of temperature coating, which is the field of coating technology. Background technique [0003] When the coating is heated to a certain temperature and changes in color or other phenomena, the coatings that indicate the surface temperature and temperature distribution of the object are called temperature coating, which is usually called color -changing coating or thermist coating.The existing temperature coatings have the following shortcomings: the surface temperature and temperature distribution of the object's surface cannot be indicated in time. Invention content [0004] The purpose of the present invention is to overcome the shortcomings of existing technology and provide a kind of temperature coating. [0005] The temperature coatings of the present invention include the following components: weighing the weight 25-30, the weight of peanitic acid 20-25, the weight of methyl cellulose 1-2, the ethyl cell...
