Embodiment 1

[0060] This example relates to the preparation of a high-temperature multi-color irreversible temperature-indicating coating for petrochemical equipment.

[0061] The experimental process of this embodiment is as follows:

[0062] (1) In 8 parts by weight of xylene, mix 14 parts by weight of ultramarine blue, 0.8 parts by weight of bentonite, 1 part by weight of fumed silica, 2 parts by weight of titanium dioxide and 2.2 parts by weight of precipitated barium sulfate, and disperse to a particle size of less than or equal to 30 microns to obtain a first mixture; and

[0063] (2) In 10 parts by weight of xylene, mix the first mixture and 62 parts by weight of silicone resin, and disperse until the particle size is less than or equal to 20 microns, to obtain the high-temperature multi-color irreversible temperature-indicating coating for petrochemical equipment according to Example 1 .

[0064] The solid content of the temperature-indicating paint according to Example 1 is 40%,...

Embodiment 2-5

[0084] The method similar to Example 1 was used to prepare the high-temperature multi-color irreversible temperature-indicating coating for petrochemical equipment according to Examples 2-5, and its temperature-indicating performance was tested under the same conditions as in Example 1. In Example 5 using butyl ester as the organic solvent, the step of adding xylene in the preparation process of Example 1 was replaced by the step of adding butyl ester. Table 1 shows the temperature-indicating paint formulations of Examples 2-5.

Abstract

This application relates to a high-temperature multi-color-changing irreversible temperature-indicating coating for petrochemical equipment, characterized in that, based on weight percentage, the raw materials used to prepare the high-temperature multi-color-changing irreversible temperature-indicating coating for petrochemical equipment include the following components: silicone resin 55‑ 75%, Ultramarine 8‑20%, Thickener 0.8‑2%, Filler 6‑15%, and Organic Solvent 6‑20%. The application also relates to a preparation method of a high-temperature multi-color-changing irreversible temperature-indicating coating for petrochemical equipment. The high-temperature multi-color-changing irreversible temperature-indicating paint for petrochemical equipment described in this paper has high temperature display accuracy, wide source of raw materials, and simple preparation process, and can be used for over-temperature warning of petrochemical equipment in the temperature range of 250°C-450°C.

Description

technical field [0001] The application relates to the technical field of coatings, in particular to a high-temperature multi-color-changing irreversible temperature-indicating coating for petrochemical equipment and a preparation method thereof. Background technique [0002] Temperature-indicating paint is a special paint that uses color changes to indicate the surface temperature and temperature distribution of objects. It is also commonly called color-changing paint or heat-sensitive paint. [0003] According to the color stability of the temperature-indicating paint after it changes color, the temperature-indicating paint can be divided into reversible temperature-indicating paint and irreversible temperature-indicating paint. When heated to a predetermined temperature, the color of the coating changes, showing a new color different from the original color of the coating at room temperature, and when it is cooled to room temperature again, the coating returns to the origi...
