Back-fire relief bag

Abstract

A fire retardant bag belonging to the fireproof sealing material field is disclosed. It relates to a bag shape fireproof material for solving problem of the complicated manufacturing technique, large investment, heavy weight and inconvenient uses of the fire retardant bag anti flaming fire proof materials. The fire retardant bag is made through enwrapping the antiflaming fireproof materials in the antiflaming bag. The antiflaming fireproof material is made by mixing the components in weight ratio as follows: chlorethene chlorovinylidene10-20, ammonium polyphosphate fire retardant 15-25, expandable graphite6-16, hollow microsphere 5-10, hydroxyethyl cellulose 1-4, calcium carbonate 20-30, water 8-15. The material of the antiflaming package is of close meshed hypo alkaline / non alkaline glass fiber cloth, the inner packaging bag of the antiflaming package bag is of thick type plastic bag. It is suitable for the fire partition or fireproof barrier of cable tunnel and cable shaft in electric power plants, electric substations, factory buildings and tall buildings.

Description

technical field [0001] The invention belongs to the field of fireproof plugging materials, and in particular relates to a bag-shaped refractory material. Background technique [0002] In terms of fire safety in buildings, separation is the most widely used design idea. However, fire-resistant partition walls and floors are often penetrated by auxiliary facilities such as cables, channels, pipes, etc., and their integrity is damaged, leaving serious fire hazards. Now, it is a consensus and necessary measure to carry out fireproof sealing on these holes and gaps. The fire-resistant bag (also known as fire-resistant bag, fire-resistant bag) that is widely used in fire-proof sealing is to use non-combustible or flame-retardant materials to constrain refractory materials into bag-shaped bodies of various specifications, which can be stacked into various forms. The wall, as a fire-resistant partition wall or fire-resistant barrier, or used to seal larger holes. [0003] An intu...

AI Technical Summary

Problems solved by technology

Flame-retardant refractory materials are composed of low-temperature layers containing slag wool and / or rock wool layers, inorganic binders and inorganic expansion layers of inorganic flame-retardant materials, and high-temperature layers of aluminum silicate fibers. The production process is long and complicated.

Flame-retardant packaging bags are flame-retardant polypropylene, polyethylene film bags or woven bags, which will be damaged when exposed to a slight fire, which is not convenient for repeated use of fire-resistant bags
