Embodiment

[0024] A kind of fire-stopping bag of the present invention, weighs each component proportioning according to listing in table 2; The larger solid raw material of particle can be poured into pulverizer and be pulverized to appropriate fineness; Each component is poured into mixer and stirred to After uniformity, weigh it, put it into an inner packing bag made of thick plastic film and seal it, and then put it into an outer flame-retardant packing bag made of fine-mesh low-alkali glass fiber cloth or alkali-free glass fiber cloth for sealing. The fire retardant package of the present invention is mainly made into the following three specifications:

[0025] 1. Flame-retardant refractory material 460 grams, flame-retardant packaging bag 320mm×240mm×30mm;

[0026] 2. Flame-retardant refractory material 230 grams, flame-retardant packaging bag 240mm×160mm×30mm;

[0027] 3. Flame-retardant refractory material 120 grams, flame-retardant packaging bag 160mm×120mm×30mm.

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...
