Environment-friendly fire-retardant module

Abstract

The invention discloses an environment-friendly fire-retardant module. The environment-friendly fire-retardant module consists of 40 to 90 weight parts of expanded vermiculite, 10 to 60 weight parts of flame-retardant resin, 5 to 30 weight parts of expanded graphite, and 5 to 30 weight parts of magnesium oxide. The environment-friendly fire-retardant module has the advantages that: the plasticity is high, and the module contributes to opening pores and cutting; the module has high performance such as water resistance, oil resistance, alkali resistance and the like, and does not have the defects of swelling, deformation and cracking; the weight is light, the actual density is 0.8g / cm<3>, and the load of blocking materials on cable bridges and buildings can be effectively lightened; the fire-resistant time is long, namely the fire-resistant time is prolonged to be more than 5 hours, and the module is a national first-class fireproof product; the module cannot produce toxic gas when encountering with fire, does not contain halogen components, cannot release toxic gas when encountering with fire hazards, and is environment-friendly; the period of validity of the product is long, namely the period of validity is over 15 years, and the repetitive investment and construction are avoided; and the module can be widely applied to the fireproof blocking of wires, cable and electrical equipment of large-scale industrial and mining enterprises in the fields of electric power, petrochemistry, metallurgy and steel, communication, national defense and the like.

Description

technical field [0001] The invention relates to a fire-blocking module, in particular to an environment-friendly fire-blocking module suitable for relatively large penetrating openings, and belongs to the technical field of building materials. Background technique [0002] In today's buildings, due to the requirements of laying wires and cables, many penetrating holes are opened between the walls and the floor to facilitate the passage of wires and cables. But these holes also have potential fire hazards: on the one hand, flames and smoke can easily spread to adjacent spaces through the holes; on the other hand, cable channels may form a shaft effect to accelerate the spread of fire. [0003] At present, fireproof sealing materials are used at home and abroad to seal the holes, so as to effectively prevent the flame from spreading through the holes. However, the existing plugging materials have defects such as poor plasticity, inconvenient disassembly, easy collapse, corros...
