Description

Self-adhesive fire extinguishing tape containing microcapsules for fire extinguishing and fire extinguishing products using the same

The present invention relates to a self-adhesive fire extinguishing tape comprising microcapsules for fire extinguishing and a fire extinguishing product using the same. have.

Encapsulation is a physico-chemical process in which a liquid, solid, or gas as a core and a shell surrounding the outside of the core are 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 isolation from the outside during storage and processing steps.

In addition, the external release of the core according to the encapsulation may vary depending on the intended use. For example, in order to take advantage of the controlled external release of the core that is released from the shell, the core can be encapsulated and used in drugs, pesticides, fragrances and mineral fertilizers. Among the various uses of this encapsulation, in particular, the technology of extinguishing a fire by releasing the fire extinguishing agent to the outside as the shell is destroyed in case of a fire including the core as a fire extinguishing agent is desperately needed in the modern society where a lot of electronic and electrical appliances are used. Various technologies are being developed according to the demand.

For example, fire extinguishing microcapsules have a fire extinguishing agent as the core and are encapsulated inside the shell. When a fire occurs, the fire extinguishing agent leaves the shell within a short time in a narrow temperature range. It can speed up fire suppression and improve the efficiency of fire suppression. However, these microcapsules for fire extinguishing are highly influenced by the external environment, and when the shell is destroyed by external force or environment and the fire extinguishing agent, which is the core, is released to the outside, the amount of fire extinguishing agent required for fire extinguishing is small at the moment when fire is needed. The problem of not meeting the concentration of the extinguishing agent may arise. Therefore, while providing an excellent extinguishing effect by securing a sufficient amount of extinguishing agent, research on a method for quickly suppressing a fire by applying various microcapsules for digestion is being actively conducted.

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

PVC tape, butyl rubber tape, etc. are mainly used for the insulation tape, and it is formed by applying an adhesive separately by the calendar method, and winding it by winding it on a covered wire or a connection part of the wire so that it is wound only by the self-adhesive force of the adhesive most of it

However, the conventional insulating tape as described above is adhered by an adhesive, and this adhesive is usually weak in heat resistance, so it is easily aged due to heat generated by the connection of the connection part of the electric wire and hardened together with the tape. The self-adhesiveness of the tape is lost, and the insulating tape detaches from the coated part and the coated part is exposed to the outside frequently. In addition, due to poor insulation of the connection connection part of the electric wire, safety accidents such as damage to human life or livestock due to an electric shock accident occur due to the connection spiral part of the exposed wire to the outside. There is a high risk of fire accidents due to short circuits caused by contact with foreign substances, so the frequency of electrical safety accidents in the real world is quite high.

Accordingly, the present inventors developed a self-adhesive fire extinguishing tape including microcapsules for fire extinguishing while researching to solve the above problems. It was found that the extinguishing agent contained in the fire extinguishing agent is released to extinguish the fire early, thereby completing the present invention.

In this regard, Korean Patent Registration No. 10-2032724 discloses a transfer printing film for a board panel containing a microencapsulated composition for fire extinguishing.
