Embodiment 1

[0036]Both are 10 parts of 230 mesh potassium nitrate and 50 parts of strontium nitrate, 5 parts of 270 mesh reducing agent and 30 parts of 80 mesh microcapsule fire extinguishing agent, mix in a high-speed mixer with a rotation speed of 1000-1500r / min, and add adhesive after mixing 50 parts, wherein, epoxy resin accounts for 55% of the mass fraction of adhesive, m-phenylenediamine accounts for 1% of the mass fraction of adhesive, acetone accounts for 44% of the mass fraction of adhesive, and then the speed of passing through is 1700- 2000r / min high-speed mixer mixed evenly to obtain a viscous aerosol-microcapsule preheating press system, and the aerosol-microcapsule preheating press system was cured at 145°C for 20 minutes, and pressed into a 1.0mm Composite fire extinguishing patch, when used, it should be covered with Nitto 500 or 3M 9495LE double-sided adhesive on one side.

Embodiment 2

[0038] All are 13 parts of 240 mesh potassium nitrate and 53 parts of strontium nitrate, 6 parts of 290 mesh reducing agent and 33 parts of 90 mesh microcapsule fire extinguishing agent, mix in a high-speed mixer with a rotation speed of 1000-1500r / min, and add adhesive after mixing 53 parts, wherein, epoxy resin accounted for 57% of the mass fraction of adhesive, m-phenylenediamine accounted for 1.2% of the mass fraction of adhesive, acetone accounted for 41.8% of the mass fraction of adhesive, and then passed through the rotating speed of 1700- 2000r / min high-speed mixer mixed evenly to obtain a viscous aerosol-microcapsule preheating press system, and the aerosol-microcapsule preheating press system was cured at a temperature of 150°C for 23 minutes, and pressed to 1.0mm The composite fire extinguishing patch, when used, should be covered with Nitto 500 or 3M 9495LE double-sided adhesive on one side.

Embodiment 3

[0040] 14 parts of 260-mesh potassium nitrate and 54 parts of strontium nitrate, 7 parts of 300-mesh reducing agent and 35 parts of 110-mesh microcapsule fire extinguishing agent are mixed in a high-speed mixer with a rotation speed of 1000-1500r / min, and the adhesive is added after mixing 55 parts, wherein, epoxy resin accounts for 60% of the mass fraction of adhesive, m-phenylenediamine accounts for 1.5% of the mass fraction of adhesive, acetone accounts for 38.5% of the mass fraction of adhesive, and then the speed of passing through is 1700- 2000r / min high-speed mixer mixed evenly to obtain a viscous aerosol-microcapsule preheating press system, and the aerosol-microcapsule preheating press system was hot-pressed at 155°C for 27 minutes to be solidified and pressed to 1.0mm The composite fire extinguishing patch, when used, should be covered with Nitto 500 or 3M 9495LE double-sided adhesive on one side.

Abstract

The invention discloses a composite fire extinguishing patch and a preparation method thereof. The composite fire extinguishing patch is prepared from the following components in parts by mass: 60-76parts of oxidizing agent, 5-8 parts of reducing agent, 30-38 parts of microcapsule fire extinguishing agent and 50-58 parts of adhesive. The method comprises the following steps: (S1) mixing the oxidizing agent, the reducing agent and the microcapsule fire extinguishing agent in a certain mass ratio; (S2) adding the adhesive into the mixture obtained in (S1) and mixing to obtain a thick aerosol-microcapsule pre-hot pressing system; (S3) performing hot pressing and curing moulding on the aerosol-microcapsule pre-hot pressing system to obtain the composite fire extinguishing patch. The compositefire extinguishing patch disclosed by the embodiment of the invention is prepared by combining the oxidizing agent, the reducing agent, the microcapsule fire extinguishing agent and the adhesive, thetrigger temperature of the composite fire extinguishing patch is reduced, the trigger sensitivity of the composite fire extinguishing material is increased, and the effects of high trigger sensitivity and high fire extinguishing speed of the composite fire extinguishing material are realized; meanwhile, due to the limited space in a socket, the use in the socket can be facilitated by adopting a form of patch.

Description

technical field [0001] The invention relates to the technical field of socket fire extinguishing, in particular to a composite fire extinguishing patch and a preparation method thereof. Background technique [0002] According to statistics, about 30% of residential electrical fires are caused by power sockets. Factors such as dust falling, long-term overload use, damage to the plug, and abnormal power consumption environment may cause the power socket to catch fire. Specifically, when the plug is inserted into the socket, it is easy to cause ignition at the solder joints, terminals, and sockets. Although the socket product uses flame-retardant PP or PC material as the product shell, and meets the heat resistance test in "GB 2099.7-2015 Household and Similar Plugs and Sockets Part 2-7: Special Requirements for Extension Cord Sockets", but due to abnormal Factors will cause the temperature around the solder joints, terminals and sockets to rise, resulting in the softening of ...
