Organic fireproofing plugging

Abstract

A fire-proof organic blocking material for blocking the through hole and gap in fire accident is prepared from diethyl silica oil, light and / or heavy calcium carbonate, expanded pearlite (and / or vermiculite), filler chosen from diatomite, talc powder and bentone, and fire retarder chosen from aluminium hydroxide, hydrated zinc borate and magnesium hydroxide. Its advantages are high effect and durable plasticity and toughness.

Description

technical field [0001] The invention relates to a refractory material, especially a fireproof blocking material for sealing penetrating openings and building gaps. Background technique [0002] According to GBJ 16-87 "Code for Fire Protection Design of Buildings" and GB 50045-95 "Code for Fire Protection Design of High-rise Civil Buildings", the penetrations (such as cables, air pipes, etc.) Openings, etc., must be fireproofed to prevent the spread of fire from one partition to another and the spread of toxic fumes in the event of a fire. Organic fireproof blocking material is the most commonly used fireproof sealing material. [0003] However, the currently used organic fireproofing materials are often cured due to the aging of the adhesive and the ambient temperature during use. After curing, some volume shrinks to form gaps, resulting in imprecise sealing, leaving a safety hazard; moreover, it is relatively hard after curing, which is not convenient for cable maintenanc...
