Embodiment 1

[0013] Embodiment 1: A kind of high-temperature-resistant coating used on pipelines is made from the following raw materials according to the mass ratio: silicone resin 10, high alumina fiber 10, cobalt oxide 15, calcium oxide 5, nano silicon dioxide 5, Propylene Glycol Methyl Ether 1, Zinc Phosphate 1, Aluminum Tripolyphosphate 1, Chrome Oxide Green 5, Traditional Chinese Medicine Extract 20. Among them, the traditional Chinese medicine extract is prepared by mixing the extracts of the following raw materials according to the mass ratio: 10 capillary wormwood, 15 motherwort grass, 1 green weed, and 5 saffron. Cr in chromium oxide green 2 o 3 The content is 90%.

[0014] After using the coating prepared in Example 1, the service life of the kiln was increased by 3 times, the heat resistance was improved by 25%, and no toxic substances were emitted during use.

Embodiment 2

[0015] Embodiment 2: A kind of high-temperature-resistant coating used on pipelines is made of the following raw materials according to the mass ratio: silicone resin 35, high alumina fiber 35, cobalt oxide 35, calcium oxide 10, nano silicon dioxide 10, Propylene glycol methyl ether 5, zinc phosphate 5, aluminum tripolyphosphate 5, chromium oxide green 15, Chinese medicine extract 35. Among them, the traditional Chinese medicine extract is prepared by mixing the extracts of the following raw materials according to the mass ratio: 20 capillary wormwood, 20 motherwort, 5 fennel, and 15 saffron. Cr in chromium oxide green 2 o 3 The content is 95%.

[0016] After adopting the coating prepared in Example 2, the service life of the kiln is doubled, the heat resistance is improved by 30%, and no toxic substances are emitted during use.

Embodiment 3

[0017] Embodiment 3: A kind of high-temperature-resistant coating that is used on pipeline, is made by the following raw materials according to mass ratio: organosilicon resin 25, high alumina fiber 20, cobalt oxide 25, calcium oxide 8, nano silicon dioxide 8, Propylene Glycol Methyl Ether 3, Zinc Phosphate 3, Aluminum Tripolyphosphate 3, Chromium Oxide Green 10, Traditional Chinese Medicine Extract 25. Among them, the traditional Chinese medicine extract is prepared by mixing the extracts of the following raw materials according to the mass ratio: 15 capillary wormwood, 18 motherwort, 3 fennel, and 10 saffron. Cr in chromium oxide green 2 o 3 The content is 99%.

[0018] After using the coating prepared in Example 3, the service life of the kiln is increased by 5 times, the heat resistance is increased by 40%, and no toxic substances are emitted during use.

Abstract

The invention provides a high temperature resistant paint for pipelines. The high temperature resistant paint is prepared from the following raw materials by mass: 10-35 of organic silicon resin, 10-35 of high aluminum fiber, 15-35 of cobalt oxide, 5-10 of calcium oxide, 5-10 of nano silicon dioxide, 1-5 of propylene glycol methyl ether, 1-5 of zinc phosphate, 1-5 of aluminum tripolyphosphate, 5-15 of chromium oxide green, and 20-35 of a Chinese medicinal extract. The paint provided by the invention has the advantages of good heat resistance, low production cost and high cost performance, also greatly improves the service life of pipelines, and at the same time is more environment-friendly.

Description

technical field [0001] The invention relates to a coating, in particular to a high-temperature-resistant coating used on pipelines. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. In many cases, pipelines need to have high temperature resistance, so there are higher requirements for coatings used for pipelines. At present, many coatings used for pipelines are not very good at high temperature. This has a great imp...
