Method for manufacturing a microcapsule fire extinguishing component, method for manufacturing a fire extinguishing patch using the fire extinguishing component, and fire extinguishing patch made therefrom.

Abstract

The present invention provides a method for producing a microencapsulated fire extinguishing component, a method for producing a fire extinguishing patch using the fire extinguishing component, and a fire extinguishing patch produced thereby. [Solution] The present invention provides a method for manufacturing a microcapsule fire extinguishing component that is excellent in moldability and durability and has a certified service life of 5 or 10 years or more, and that can be applied to a variety of electrical and electronic products or home appliances, including electrical outlets, and can maintain fire extinguishing effectiveness for the service life of the applied product or longer, and is also excellent in terms of initial fire extinguishing performance and sustained fire extinguishing performance by mixing two types of microcapsules of different sizes as microcapsules of the fire extinguishing component, a method for manufacturing a fire extinguishing patch using the fire extinguishing component, and a fire extinguishing patch manufactured thereby, which contains 8 to 15 parts by weight of plasticizer, 6 to 19 parts by weight of hardener, and 60 to 100 parts by weight of synthetic resin component per 100 parts by weight of the microcapsule-type fire extinguishing component.

Claims

1. For every 100 parts by weight of the microencapsulated fire extinguishing component, prepare 8 to 15 parts by weight of plasticizer, 6 to 19 parts by weight of hardener, and 60 to 100 parts by weight of synthetic resin component. A method for manufacturing a microcapsule fire extinguishing patch, comprising a primary stirring step of stirring the synthetic resin component and the plasticizer, a secondary stirring step of adding the microcapsule-type fire extinguishing component and stirring, and a molding step of pouring the obtained mixture into a molding frame and molding it.

2. The method for manufacturing a microcapsule fire extinguishing patch according to claim 1, wherein the microcapsules of the microcapsule-type fire extinguishing component consist of two types of microcapsules with different capsule sizes: microcapsules with a capsule size of #70 to 150 mesh as the first fire extinguishing component and microcapsules with a capsule size of #250 to 350 mesh as the second fire extinguishing component, and the amount of each used is 500 to 650 parts by weight of the second fire extinguishing component per 100 parts by weight of the first fire extinguishing component.

3. The plasticizer is selected from the group consisting of dibutyl phthalate (DBP), glycerol, ethylene glycol, triethylene glycol, triacetin, triethylene glycol diacetate (TEGDA), ethylene vinyl acetate, polyvinyl alcohol, glycerin triacetate, dioctyl (nonyl) terephthalate, dioctyl terephthalate, sodium oleate, oleic acid, or combinations thereof. The aforementioned primary stirring step involves stirring at a relatively high speed (700-900 rpm) for 12-18 minutes. The method for manufacturing a microcapsule fire extinguishing patch according to claim 1 or 2, characterized in that the secondary stirring stage is performed in two separate stages of 2-1, 2-2, and 2-3, each lasting 3 to 8 minutes at a relatively low speed (400 to 600 rpm), and complete stirring is achieved through vibration or reversal oscillation processes of the stirring tank itself during each stage.

4. Manufactured by the manufacturing method described in claim 1, The product contains 8 to 15 parts by weight of plasticizer, 6 to 19 parts by weight of hardener, and 60 to 100 parts by weight of synthetic resin component per 100 parts by weight of microencapsulated fire extinguishing component. The microcapsules of the aforementioned microcapsule-type fire extinguishing component are a mixture of two types with different capsule sizes: microcapsules with a capsule size of #70 to #150 mesh as the first fire extinguishing component, and microcapsules with a capsule size of #250 to #350 mesh as the second fire extinguishing component, in an amount of 500 to 650 parts by weight of the second fire extinguishing component per 100 parts by weight of the first fire extinguishing component. The aforementioned plasticizer is selected from the group consisting of dibutyl phthalate (DBP), glycerol, ethylene glycol, triethylene glycol, triacetin, triethylene glycol diacetate (TEGDA), ethylene vinyl acetate, polyvinyl alcohol, glycerin triacetate, dioctyl (nonyl) terephthalate, dioctyl terephthalate, sodium oleate, oleic acid, or a combination thereof, and is a microcapsule fire extinguishing patch.
