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
The present invention relates to a kind of fire resistant anticorrosive allochroic paint.
Background technology
In the catalysis and cracking unit and various high-temperature pipe of petroleum refining industry, because working temperature is higher, the lining material of pipe interior and thermal insulation layer likely can damage, and can cause pipe temperature sharply to rise, and may damage whole device or serious security incident occurs.Current method is to detect an appearance temperature at interval of 2 hours, to know whether interior lining destroys, whether react normal.Generally to adopt thermopair and thermometer to carry out detected temperatures, but thermopair can only be tested the temperature of a bit, thermometer can only test gas or the temperature of solution medium field, but measure for those big area high temperature positions too far behind to catch up, the just more difficult measurement in some baroque places.
Summary of the invention
The object of the invention is to be to solve the problem of above-mentioned prior art, a kind of fire resistant anticorrosive allochroic paint is provided, brushing, at the outside surface of various high-temperature pipes, can, by observing the color of allochroic paint, can judge whether pipe interior lining or thermal insulation layer damage.
A kind of fire resistant anticorrosive allochroic paint, by weight, comprising: 50 parts～70 parts of organic-silicon-modified resins; 10 parts～15 parts of titanium dioxides; 8 parts～16 parts of colored pigments; 1 part～2 parts of anti-settling agents; 0.1 part～1 part of variable color auxiliary agent; 4 parts～15 parts of metal-powders; 4 parts～8 parts of mixed solvents.
In the present invention, described metal-powder is calcium powder, magnesium powder, receive any one or a few in powder.
In the present invention, described mixed solvent is any one or a few in toluene, dimethylbenzene or propyl carbinol.
In the present invention, described colored pigment is the mixture of blue pigment and phthalocyanine.
Preferred version of the present invention is, described phthalocyanine is inorganic phthalocyanine, and described blue pigment is inorganic blue pigment.
The beneficial effect that the present invention has: be coated with and be covered with allochroic paint at catalysis and cracking unit and various band temperature pipeline external surface, when after the lining material or thermal insulation layer destruction of pipe interior, can cause the temperature of destruction place pipeline surfaces externally and internally sharply to rise, when pipeline external surface temperature rise is after certain value, brushing can change in the allochroic paint color of pipeline external surface, thereby can judge that the lining material of this place's pipe interior or thermal insulation layer damage, can adopt various measures to equipment, to avoid causing more serious consequence.
Due in the time that certain value is arrived in temperature rise, allochroic paint color can change automatically, therefore, only need to be in observation ward's monitoring, accuracy of judgement and convenient, safety.
In addition, the source of colored pigment is more extensive, except inorganic blue pigment and inorganic phthalocyanine, also can adopt the pigment of other colors.Example: in the time that colored pigment is the mixture of inorganic blue pigment and inorganic phthalocyanine, the color of finished product is blue-greenish colour, if the lining material of pipe interior or thermal insulation layer have damage, when the temperature of pipeline external exceedes 350 DEG C, glaucous allochroic paint will yellowing.
