Abstract

The invention relates to a high temperature resistant and anticorrosion color-variable paint, which comprises, by weight, 50-70 parts of organosilicon modified resin, titanium dioxide 10-15 parts of titanium dioxide, 8-16 parts of a colored pigment, 1-2 parts of an anti-settling agent, 0.1-1 part of a color change assistant, 4-15 parts of metal powder, and 4-8 parts of a mixed solvent. By coating the outer surfaces of catalytic and cracking units and a variety of high temperature pipelines with the color-variable paint, when pipeline inner linings or thermal insulation layers are damaged, the temperature rise can make the color-variable paint changes in color change, thereby playing a very good warning role.

Description

technical field [0001] The invention relates to a high temperature resistant anti-corrosion discoloration paint. Background technique [0002] In the catalytic and cracking units and various high-temperature pipelines in the oil refining industry, due to the high working temperature, the lining material and insulation layer inside the pipeline may be damaged, which will cause the temperature of the pipeline to rise sharply, which may damage the entire device or cause serious accidents. security incident. The current method is to check the surface temperature every 2 hours to know whether the inner lining is damaged and whether the reaction is normal. Generally, thermocouples and thermometers are used to detect temperature, but thermocouples can only test the temperature at one point, and thermometers can only test the temperature of the gas or solution medium field, but it is beyond the reach of those large-scale high-temperature parts. harder to measure.
