Abstract

The invention provides a special reversible temperature indicating light stable coating for a transformer pile head and a preparation method for the coating. The coating comprises the following components in parts by mass: 40-75 parts of epoxy resin, 10-30 parts of temperature sensing powder, 1-5 parts of a dispersant, 1-5 parts of a flatting agent, 1-3 parts of a defoamer, 1-5 parts of an anti-settling agent, 5-20 parts of a solvent, 1-10 parts of sericite powder, 1-5 parts of aluminum-magnesium silicate and 1-10 parts of an ultraviolet absorbent; the component B comprises 50-100 parts of an epoxy curing agent and 0-5 parts of xylene. The mass ratio of the component A and the component B is 1: (0.7-1). The product provided by the invention has good sun protecting and antiaging properties, and can indicate change of the temperature of the transformer pile head by virtue of change of colors. Moreover, the temperature change rate is fast, the temperature restoring time is short, and meanwhile, the preparation method is simple and the cost is low.

Description

technical field [0001] The invention relates to the technical field of paint manufacturing, in particular to a special reversible temperature-indicating and light-stabilizing paint for transformer pile heads and a preparation method thereof. Background technique [0002] The power transformer is an important electrical equipment in the power supply network. Its performance can directly affect the power supply service level. The oxidation and weathering of the pile head paint will seriously cause the paint to fall off, which may cause serious consequences. [0003] Temperature-indicating paint is a new type of special paint. It uses color or appearance to indicate the surface temperature and temperature distribution of objects. Measuring and indicating temperature with temperature-showing paint has the advantages of simplicity, speed, convenience, and intuition. Thermometers, thermocouples, and thermal resistance thermometers are inferior. Due to its special use value, it h...
