Problems solved by technology

However, the fire blanket does not have any explosion-proof protection, and can only play a certain role against the ablation of open flames. Because of its general heat insulation effect, once the temperature of the open flame is too high, the heat will be transferred to the cable skin, causing damage, thus affecting Wire and cable safety performance

preparation example Construction

[0062] like Image 6 Shown, a kind of preparation method of fireproof explosion-proof blanket, it comprises:

[0063] S1, forming a composite fireproof film;

[0064] S2. Stitching the composite fireproof film to form multiple cavities;

[0065] S3, filling heat-insulating fillers in the plurality of cavities to form a fire-proof and heat-insulating intermediate;

[0066] S4. Coating an explosion-proof layer on the outside of the fire-proof and heat-insulating intermediate;

[0067] S5. Coating a flame-retardant and waterproof layer on the outside of the explosion-proof layer to prepare a fire-proof and explosion-proof blanket.

[0068] In a preferred embodiment, in the step S1, the flame retardant silicone rubber and the glass fiber woven cloth are compounded to form a composite fireproof film through a calendering process or a molding process.

[0069] In S2, it includes cutting the composite fireproof film; folding the cut composite fireproof film in half, or providing ...

Embodiment 1

[0074] 1) Coating flame-retardant silicone rubber with a flame-retardant grade of V0 (purchased from Shenzhen Zhengan Organic Silicon Material Co., Ltd.) on one side of the glass fiber woven cloth through a calendering process to prepare a composite fire-resistant film; wherein, the calendering process The temperature is 180℃±5℃; the rolling speed is 20m / min; the thickness of the formed composite fireproof film is 0.5mm;

[0075] 2) Cut the calendered composite fireproof film on the platform to a rectangle with a size of 1000mm*800mm, then sew the upper and lower layers of composite fireproof film with nylon flame retardant thread, and after sewing, the gap between the two layers of composite fireproof film The cross-sectional shape of the cavity is triangular;

[0076] 3) Mix magnesium hydroxide and aluminum oxide in proportion to form thermal insulation filler, fill the thermal insulation filler into the above cavity, and then sew the opening of the cavity for edge sealing t...

Embodiment 2

[0081] 1) Coating flame-retardant silicone rubber with a flame-retardant grade of V0 (purchased from Shenzhen Zhengan Organic Silicon Material Co., Ltd.) on the surface of one side of the glass fiber woven cloth through a molding process to prepare a composite fire-resistant film, the temperature of the molding process The temperature is 200℃±5℃, and the thickness of the composite fireproof film is 0.8mm;

[0082] 2) Cut the molded composite fireproof film into two pieces on the platform, cut a rectangle with a size of 1000mm * 850mm, and then sew the upper and lower layers of composite sheets with nylon flame-retardant thread, and then composite the fireproof film The cross-sectional shape of the cavity between them is circular;

Abstract

The invention provides a fire-proof and explosion-proof blanket and a preparation method thereof. The fire-proof and explosion-proof blanket comprises a fire-proof and heat-insulation intermediate; an explosion-proof layer coated on the outer side of the fire-proof and heat-insulating middle body; and a flame-retardant waterproof layer covering the outer side of the explosion-proof layer; wherein the fire-proof heat insulation intermediate comprises a composite fire-proof rubber sheet, and the composite fire-proof rubber sheet is formed by compounding flame-retardant silicone rubber and glass fiber woven cloth. According to the fire-proof and explosion-proof blanket, the fire-proof and heat-insulation intermediate is wrapped by the explosion-proof layer, then the outer side of the explosion-proof layer is wrapped by the flame-retardant and waterproof layer, and due to the fact that all layers of materials have good flexibility, the fire-proof and explosion-proof blanket has the advantages of being good in flexibility, convenient to install and capable of being suitable for different special occasions; and the fire-proof and explosion-proof blanket product can be randomly cut into any size, so that different requirements can be met. In addition, the product also has better fire-proof, flame-retardant, heat-insulating and waterproof performances.

Description

technical field [0001] The invention relates to a fireproof explosion-proof blanket and a preparation method thereof. Background technique [0002] The substation in the power system undertakes the task of transforming voltage, converging and distributing electric energy. Its special functions and requirements make the substation equipped with inflammable and explosive equipment such as transformers, circuit breakers, cables, and capacitors. A large number of wires and cables are often densely arranged in cable tunnels or cable trenches. Most of the preventive measures used at this stage are explosion-proof boxes, fire-resistant coatings or fire-resistant bags. The above preventive measures have the problems of excessive volume, difficult installation, complicated installation process, good fire prevention effect but high cost in use. [0003] In order to solve the above problems, people have done a lot of improvement work. When designing fire and explosion-proof products,...
