Description

Self-adhesive fire extinguishing tape including fire extinguishing microcapsules and fire extinguishing products using the same {SELF-STICK FIRE EXTINGUISHING TAPE INCLUDING MICROCAPSULE FOR FIRE EXTINGUISHING AND FIRE EXTINGUISHING PRODUCT USING THE SAME}

The present invention relates to a self-adhesive fire extinguishing tape including a fire extinguishing microcapsule and a fire extinguishing product using the same, and more specifically, the fire extinguishing tape has its own adhesive property and can be easily attached to an object. have.

Encapsulation is a physico-chemical process in which a liquid, solid, or gas is used as a core and a shell surrounding the outside of the core is formed. Prevent interaction. The main purpose of such encapsulation is the controlled external release of the encapsulated core, in which case the encapsulated core generally requires complete separation from the outside during the storage and processing steps.

In addition, the external release of the core upon encapsulation may vary depending on the intended use. For example, in order to take advantage of the controlled external release of the core released from the shell, the core may be encapsulated and used in drugs, pesticides, flavors and mineral fertilizers. Among the various uses of such encapsulation, the technology of extinguishing fire by extinguishing the shell by destroying the shell in case of fire by including the core as a extinguishing agent is urgently needed in the modern society where many electronic products and electric products are used. Various technologies are being developed as required.

For example, a fire extinguishing microcapsule is encapsulated inside the shell with a fire extinguishing agent as the core, and when a fire occurs, the fire extinguishing agent leaves the shell within a short time within a narrow temperature range, resulting in decapsulation (decapsulation). It can quickly extinguish fire and improve the efficiency of fire extinguishing. However, these extinguishing microcapsules are highly affected by the external environment, and if the shell is destroyed by external force or the environment and the core extinguishing agent is released to the outside, the amount of extinguishing agent is small at the moment when it is necessary to extinguish a fire. Problems can arise that do not meet the concentration of the extinguishing agent. Therefore, while providing an excellent digestive effect by securing a sufficient amount of digestive agents, research on a method for quickly suppressing a topic by applying various digestive microcapsules is being actively conducted.

On the other hand, in the case of wires, it is common to prevent safety accidents such as fire and electric shock due to corrosion of wire connection parts, short circuits, short circuits, etc. by wrapping insulation tape around the wiring and stripping parts of the wires exposed to the outside.

PVC tapes, butyl rubber tapes, etc. are mainly used as such insulation tapes, and they are formed by separately applying an adhesive by the calendar method, and wrapped around the coated wire or the connecting part of the wire so that it is wound only with the self-adhesive force of the adhesive. Most of them.

However, the conventional insulating tape as described above is adhered by an adhesive, and such an adhesive is usually weak in heat resistance, so it is easily aged due to heat generated by the connection of the connecting part of the wire and hardened together with the tape. The tape's self-adhesion is lost and the insulating tape leaves the coated area, and the coated area is exposed to the outside. In addition, safety accidents such as damage to humans or livestock due to electric shock accidents occur due to poor insulation of the connection parts of the wires exposed to the outside, and there is a short circuit from the wires connected to the exposed wires. It is a reality that the frequency of electrical safety accidents is quite high in the real world because there is a high risk of a fire accident, such as a short circuit caused by contact with foreign substances.

Accordingly, the inventors of the present invention developed a self-adhesive fire extinguishing tape including a fire extinguishing microcapsule, while researching to solve the above problems, and if it is coated on an object such as an electric wire, the fire extinguishing microcapsule The present invention was completed by discovering that the fire extinguishing agent contained in the extinguishing agent can be released early to extinguish the fire.
