Anti-condensation flame-retardant self-leveling foaming plugging material as well as preparation method and application thereof

Abstract

The invention discloses an anti-condensation flame-retardant self-leveling foaming plugging material as well as a preparation method and application thereof. The plugging material is prepared from a material A, a material B and a material C, wherein the material A contains 39.48 wt% of polypropylene glycol, 2.1 wt% of a foam stabilizer and 0.42 wt% of a catalyst; the material B contains 42wt% of isocyanate; and the material C contains 16w% of expandable graphite powder. The preparation method comprises the following steps: respectively mixing and packaging the material A, the material B and the material C; the plugging material can be applied to power equipment. The plugging material provided by the invention has a flame-retardant grade of V-0, and belongs to a flame-retardant material; good heat preservation and heat insulation performance is realized; the paint can be used for a long time at the temperature of-30 DEG C to 90 DEG C. Before use, the material is a liquid material whichis halogen-free and does not contain VOC substances; flame combustion of the sealing block is low-smoke and non-toxic.

Description

technical field [0001] The invention relates to the field of materials, in particular to an anti-condensation flame-retardant self-leveling foaming plugging material and a preparation method and application thereof. Background technique [0002] With the development of my country's economic construction, various industries put forward higher requirements for the comprehensive performance and environmental protection of fireproof sealing products. However, traditional fireproof sealing materials such as inorganic fireproof blocking materials, organic fireproof blocking materials, and fire retardant bags have gradually revealed limitations in practice and application. With the continuous development of thermal expansion fireproofing technology (Intumex Technology) in the world, the development and application of building fireproofing and sealing materials with high-efficiency intumescent flame-retardant properties, convenient construction and low price that meet environmental ...

AI Technical Summary

Problems solved by technology

[0003] However, some existing sealing materials have unstable performance and poor sealing effect, and water vapor can still enter the cabinet of power supply and distribution equipment

And it is not completely waterproof, the flame retardant level is low, the service life is short, and the use effect is easily affected by the external environment
