Abstract: An environment-friendly fire-retardant coating comprises a coating substrate and fire-extinguishing agent microcapsules which can be ruptured and vaporized to a release fire-extinguishing material to achieve the purposes of cooling and/or fire prevention and/or fire extinguishing upon being exposed to a temperature of not less than 75° C. and/or an open flame environment. In order to break the current situation that the traditional fire-prevention, fire-extinguishing and flame-retardant coatings can only prevent the spread of the fire area, but it is difficult to extinguish the fire sensitively and actively in a short time, there are provided a variety of coatings and/or films which can actively cool down, prevent fire and extinguish the fire, have short response time, have stable fire-extinguishing components in the coatings and/or films, with the films being able to trigger the fire extinguishment repeatedly.

Abstract: A perfluorohexanone microcapsule with a high core-wall ratio is provided. In the perfluorohexanone microcapsule, there is no need for auxiliary materials/fillers and other adsorption or high-boiling solvent to dissolve perfluorohexanone. By coating the microcapsule shell with secondary polymers, the shell strength of the microcapsule is improved, the volatilization loss of perfluorohexanone is reduced, and the problem of short storage life of the perfluorohexanone microcapsule material is overcome, so that it has commercial application value. The perfluorohexanone microcapsule can be further compounded with various materials and interfaces to obtain various fire extinguishing materials with perfluorohexanone microcapsule as the core component.
