Problems solved by technology

[0005] The fire retardant module is a good alternative material. Most of the current fire retardant modules are composed of vermiculite and adhesives. For example, patent ZL200610114013.7 discloses a fire retardant module made of raw vermiculite, cooked vermiculite, graphite and Adhesive, but vermiculite has a high density, and a large amount of use will inevitably increase the load-bearing burden. Moreover, it is not convenient for transportation and processing, and the processing cost is relatively high.

Embodiment 1

[0042] Step 1: Break the oak bark into cork particles and sort them by particle size.

[0043] According to needs, select the cork particle of suitable particle size, for example be less than 11000g of the cork particle of 14 mesh specification, be greater than or equal to the 5000g of the cork particle of 14 mesh specification.

[0044] Step 2: Mix cork particles, flame retardant, preservative and adhesive evenly; then compact.

[0045] Cork particles smaller than 14 mesh: 11000g Cork particles greater than or equal to 14 mesh: 5000g Antimony trioxide: 250g Chlorinated paraffins: 100g benzoic acid: 1000g PX-60: 1000g Polyurethane adhesive: 3000g

[0046] The above components are mixed evenly, and then compacted.

[0047] Step 3: After compacting, heat for curing.

[0048] When curing, the temperature is selected to be 120°C; the curing time is selected to be 6 hours.

[0049] Cured by heat, the adhesive holds the cork parti...

Abstract

The invention relates to a sealing plug for plugging a cable hole and a production method thereof. The sealing plug comprises components such as cork granules with different granularities, an adhesive, a flame retardant, a preservative and the like, and is produced by a process flow comprising smashing, separation, compaction, solidification, blank cutting, molding, packaging and the like The combustion rate of the sealing plug is 28.7 mm / min, and reaches the flame retardant rating HB of a UL94 standard.

Description

technical field [0001] The invention relates to a fire retardant module for sealing cable holes and a production method thereof, in particular to a sealing plug with good flame retardant and fireproof effects and a production method thereof. Background technique [0002] Cable is an important carrier of electric energy transmission and information transmission, and its main function is to transmit energy and signals; among them, the transmission energy is realized by AC and DC power cables of various voltage levels from 110V to 220V. At present, the cable laying method widely used in substations is pipe laying. , Groove box covering laying, cable trench laying, shelf support laying and tunnel laying, etc. However, because the monitoring measures for safe operation of cables are relatively single, timely and effective detection and control of accidents such as cable fires or unsafe hidden dangers in cable operation cannot be achieved, and the safe operation of substations is ...
