Problems solved by technology

However, rock wool particles cannot withstand the high temperature of 1000°C, and the fire temperature is higher than this temperature. Therefore, when a fire occurs, the ordinary fire-resistant package is useless and cannot achieve the purpose of fire prevention and fire resistance.

Embodiment 1

[0009] (1) Weighing and batching: Before batching, the weighing scale must be calibrated, and after calibration, various raw materials can be measured. The ingredients are weighed according to 45.0% of aluminum silicate fiber cotton particles; 55.0% of raw vermiculite. (2) Stirring and filling: Use the corresponding self-made measuring cup to measure the aluminum silicate fiber cotton particles and vermiculite required for a single flame retardant package, pour them into the container, and then stir to fill a single flame retardant package. (3) Sealing of the flame retardant bag: Use a special sewing machine to sew and seal the measured small bag. The seam should not have skipped stitches, tension, leakage, etc. When sealing, the air in the flame retardant bag should be as much as possible. (4) Inspection and warehousing: the inspection shall be carried out by the personnel of the quality inspection department, and the packaging and warehousing can only be carried out after pa...

Embodiment 2

[0011] (1) Weighing ingredients: Before ingredients, the weighing scale must be calibrated. After calibration, various raw materials can be measured. The ingredients are weighed according to 46.0% of aluminum silicate fiber cotton particles and 54.0% of raw vermiculite. (2) Stirring and filling: Use the corresponding self-made measuring cup to measure the aluminum silicate fiber cotton particles and vermiculite required for a single flame retardant package, pour them into the container, and then stir to fill a single flame retardant package. (3) Sealing of the flame retardant package Use a special sewing machine to sew and seal the measured small bag. The seam should not have skipped stitches, tension, leakage, etc. When sealing, try to squeeze out the air in the flame retardant package as much as possible. (4) Inspection and warehousing: the inspection shall be carried out by the personnel of the quality inspection department, and the packaging and warehousing can only be carr...

Abstract

The invention relates to a preparation method of a high-temperature resistance firestopping pillow. According to the weight percentage, the compounding of the raw material is 40.0%-50.0% of aluminum silicate fiber cotton particle and 50.0%-60.0% of raw vermiculite. The manufacturing steps are that (1) weighing and dosing; (2) mixing and pouring; (3) sealing of firestopping pillow; (4) detection and storage. The invention provides the firestoppign pillow which is widely applied to the cable engineering in industries such as power, metallurgy, petrochemicals, buildings, etc. and can resist the high temperature which is more than 1000 DEG C. The invention has the advantages of light bulk density, good fireproof performance, long firestopping time, convenient disassembly and assembly, repeated application after disassembly, etc.

Description

1. Technical field [0001] The invention relates to a manufacturing method of a fire-resisting bag, in particular to a manufacturing method of a high-temperature resistant fire-resisting bag. 2. Background technology [0002] At present, the engineering flame retardant package used in wire and cable engineering mainly uses rock wool particles, hydroxyethyl cellulose and raw vermiculite as raw materials to manufacture the flame retardant package. The manufacturing process of the bag, Chinese patent CN1073707, its raw materials are: non-combustible refractory material rock wool, diatomite, organic silicon adhesive and vermiculite, etc.; Chinese patent CN1565673 of the fire-resistant bag disclosed by the Sichuan Fire Protection Research Institute of the Ministry of Public Security, its The raw materials are: chlorine partial emulsion 10%-20%, ammonium polyphosphate flame retardant 15%-25%, expanded graphite 6%-16%, hollow microbeads 5%-10%, hydroxyethyl cellulose 1%-4% %, calci...
