Novel fireproof moistureproof plugging material applied to electrical equipment cabinet

Abstract

The invention discloses a novel fireproof moistureproof plugging material applied to an electrical equipment cabinet, and mainly relates to the technical field of new materials. The novel fireproof moistureproof plugging material comprises a component material A and a component material B. The component material A comprises, by mass, 59.2% of silicone oil, 14.8% of muscovite, 14.8% of aluminum hydroxide, 3% of siliceous lime, 5.96% of zinc borate, 0.47% of graphite, 0.59% of chloroplatinic acid, and 1.18% of hydroxyl silicone oil. The component material B comprises the following components in percentage by mass: 9% of dibutyltin dilaurate and 91% of tetraethoxysilane. The component material A and the component material B are fully mixed according to a mass ratio of 16: 1; after being mixed together, the component material A and the component material B are mainly subjected to a physical reaction to generate heat, some low-melting-point fillers are melted through the generated heat, then some particles such as silicon dioxide are generated, and the particles are bonded with the fillers together; and therefore, a compact fireproof barrier layer is formed, so fireproof effect is achieved.

Description

technical field [0001] The invention mainly relates to the technical field of new materials, in particular to a novel fireproof and moistureproof sealing material applied to electrical equipment cabinets. Background technique [0002] Fireproof sealing products are mainly used in the field of hole and gap sealing of bridges, cables, and pipelines in industries such as electric power, rail transit, and construction engineering. The existing fireproof sealing materials are divided into organic and inorganic. The organic material is mainly flexible fireproof mud, which has good fireproof performance, but the sealing performance is relatively poor; other inorganic blocking materials mainly include fireproof package, fireproof module, and fireproof sealing plate, the main components of which contain halogen flame retardants, which will burn in case of fire. The release of toxic fumes from time to time is the common shortcoming of poor sealing performance. In addition, there are ...

Problems solved by technology

The organic material is mainly flexible fireproof mud, which has good fireproof performance, but the sealing performance is relatively poor; other inorganic blocking materials mainly include fireproof package, fireproof module, and fireproof sealing plate, the main components of which contain halogen flame retardants, which will burn in case of fire. Toxic fumes are released from time to time, which are common disadvantages of poor sealing performance

In addition, there are organic polymer foam-type sealing materials, which have limited application range and have certain deficiencies in fire prevention and sealing performance

[0003] At present, the fireproof sealing material used in electric power engineering construction is fireproof mud, which is a kind of flexible flame-retardant material, mainly used for the hole sealing of wires and cables, and the gaps at the bottom of electrical equipment cabinets are sealed to prevent wires, In the event of a cable fire, the cable spreads from the hole to the adjacent room and adjacent ditch to reduce the fire loss. However, the existing fireproof sealing material will be delaminated and separated during the solidification process, which makes it easy to shrink after solidification and hardening, forming a crescent surface. During the construction process, it is easy to cause the surface to be flat, but the internal void is blocked, which cannot be fully filled, the sealing effect is poor, and it cannot be effectively flame-retardant
