A new type of organic/inorganic intumescent fireproof elastomer board and its preparation method

Abstract

The invention discloses a novel organic / inorganic expanded type fireproof elastomer plate which comprises the following raw materials in percentage by weight: 10-35% of hydroxyl silicone oil, 5-30% of polymethylvinylsiloxane, 5-20% of hydrogen-containing silicone oil, 0-40% of inorganic flame-retardant fireproof filler, 15-50% of organic flame-retardant fireproof filler, 9-30% of other fillers, 0.1-0.5% of catalyst and 0.1-0.5% of inhibitor. The novel organic / inorganic expanded type fireproof elastomer plate is used for plugging an electrical panel cabinet, a cable shaft, a cable bridge and other large holes, and has the characteristics of long fireproof time, good smoke airtightness, attractive appearance, resistance against the shock of fire-fighting water, easy expansion, long fireproof service life and the like.

Description

Technical field: [0001] The invention relates to a novel organic / inorganic expansion type fireproof elastomer board and a preparation method thereof. Background technique: [0002] In the seams, openings or holes of electrical cabinets, cable shafts and buildings, there are often many and miscellaneous wires, cables and various communication cables. Once a fire breaks out, the fire will spread rapidly through these places, and the toxic gas will also spread rapidly thereupon. Therefore, using fireproof boards to effectively block these places can effectively control the fire within a certain range and reduce losses, thus gaining valuable time for fire fighting. [0003] Common sealing materials such as fire-resistant mud and fire-resistant bags can meet the needs of easy expansion, but the performance of fire-proof life, fire-proof time, aesthetics, resistance to fire-fighting water stamping, and smoke air tightness are poor; general silicate seals Although the plugging ma...

Problems solved by technology

[0003] Common sealing materials such as fire-resistant mud and fire-resistant bags can meet the needs of easy expansion, but the performance of fire-proof life, fire-proof time, aesthetics, resistance to fire-fighting water stamping, and smoke air tightness are poor; general silicate seals Although the plugging material has good performances such as beautiful appearance, fire-fighting water impact resistance, and smoke air tightness, it is quite lacking in the secondary crossing expansion of wires and cables, fire protection timeliness, fire protection life, etc.
