Description

technical field [0001] The invention relates to a black temperature-changing paint, in particular to a black temperature-changing paint widely used for surface decoration of industrial products such as stainless steel, aluminum alloy, cast iron and bakelite. Background technique [0002] Thermochromic materials are functional materials whose color changes significantly with temperature within a certain temperature range. As early as more than a hundred years ago, people discovered the phenomenon of thermal discoloration. The comprehensive research and application of thermochromic materials has a history of 60 to 70 years, and it has a history of more than 30 years in our country. After decades of research and development, people have developed various materials with thermochromic properties such as inorganic, organic, liquid crystal, polymer and biomacromolecules.

AI Technical Summary

Problems solved by technology

[0003] At present, ordinary paint is used for the protection of boilers, chemical reaction towers, exhaust pipes, chimneys, ovens and other metal substrate equipment pipelines, which cannot show changes in the temperature of the equipment surface in the environment, and higher temperatures may cause The paint on the surface of the equipment falls off, exposing the equipment to the environment, causing serious corrosion and shortening the life of the equipment

On the other hand, in production, due to the high temperature of the equipment, it is difficult for workers to master the operation. Therefore, there is an urgent need on the market for a simple, low-cost surface decoration and a coating that automatically changes color of the paint film.
