Abstract

The invention discloses temperature-resistant anti-corrosion color-changing paint and a preparation method thereof. The temperature-resistant anti-corrosion color-changing paint is prepared from the following raw materials in proportions: 55-60% of carboxy-terminated hyperbranched polyamide resin, 10-15% of titanium dioxide, 5-10% of hollow beads, 5-10% of anti-rust pigment, 5-10% of active nano-calcium, 0.1-0.2% of graphene, 2-2.5% of a dispersant, 0.1-0.3% of a defoamer, 1-2% of an anti-flash rust additive, 0.5-1% of a substrate wetting agent, 0.5-1% of a thickener, 20-30% of deionized water, 3-5% of a curing agent and 10-15% of color-changing pigment. The environmentally-friendly temperature-resistant anti-corrosion color-changing paint prepared with the preparation method provided by the invention is one-component water-based industrial paint. The anti-corrosion color-changing paint is not only resistant to high temperature and corrosion, but also has a wide range of applications,and is suitable for special work in the painting field.

Description

technical field

[0001] The invention belongs to the technical field of industrial coatings, in particular to a temperature-resistant, anti-corrosion and discoloration coating and a preparation method thereof. Background technique

[0002] In the petrochemical industry, many large-scale petroleum and chemical equipment, such as: hydrocracking furnaces in refineries, conversion reactors in methanol production units, gasifiers in fertilizer plants, gas headers for primary reformers, secondary reformers, and waste heat boilers , ammonia synthesis tower, etc., there are various chemical substances in it for various physical and chemical effects, and sometimes they are still operating under high temperature or high temperature and high pressure environment. Therefore, before putting into operation, the equipment is required to have safety measures, and the equipment's Temperature control is one of the keys to safe production.

[0003] The usual temperature measuring device can on...
