Embodiment 1

[0036] A preparation method of an environment-friendly fire retardant bag, comprising the following steps:

[0037] (1) Preparation of braided outer layer

[0038] Zirconia fiber and basalt fiber are used to weave the outer wrapping bag of the fire-resistant bag;

[0039] (2) Preparation of internal filler

[0040] Take 20 parts by weight of montmorillonite, 7 parts of zirconia fiber, 24 parts of glass fiber, 48 parts of aluminum silicate, 4.2 parts of raw vermiculite, and 22 parts of silicone rubber. After mixing the above raw materials in proportion, use a high-speed mixer to Stir for 50min at a rotating speed of 1500r / min, and then granulate;

[0041] (3) Fill the inner filler prepared in step (2) into the braided outer layer prepared in step (1), and encapsulate to obtain a fire-resistant bag.

[0042] Preferably, the montmorillonite is modified, and the specific steps are as follows:

[0043] (1), prepare aqueous polyurethane suspension,

[0044] a. Heat 100 parts of...

Embodiment 2

[0063] Compared with Example 1, the internal filler is made of the following raw materials by weight: 20 parts of montmorillonite, 8 parts of zirconia fiber, 24 parts of glass fiber, 48 parts of aluminum silicate, 5 parts of raw vermiculite, 23 parts of silicone rubber.

Embodiment 3

[0065] Compared with Example 1, the proportions of the raw materials in this application are consistent, and the montmorillonite is not modified.

Abstract

The invention relates to a preparation method of an environment-friendly fire protection pillow. The preparation method comprises the following steps of (1) preparing a knitted outer layer; (2) preparing an internal filling material; and (3) filling the knitted outer layer prepared in the step (1) with the internal filling material well prepared in the step (2), and encapsulating, so as to obtainthe fire protection pillow. Relative to a conventional fire protection pillow, the use levels of swelling agents of vermiculite and the like can be obviously decreased; in this way, the use level of an inflaming-retarding material can be more increased; the fire retarding effect is promoted; and the cost of the fire protection pillow provided by the application is decreased by 15% or above relative to the cost when zirconia and alumina fibers are massively used.

Description

technical field [0001] The application belongs to the field of refractory materials, and in particular relates to a preparation method of an environment-friendly fire-resistant bag. Background technique [0002] The outer layer of the fire retardant bag is made of tightly woven, specially treated and durable glass fiber cloth, which is filled with special fire-resistant, heat insulating materials and expansion materials. The fire retardant bag is non-combustible, and the fire resistance limit can reach more than 4 hours. Expands and solidifies at higher temperatures. It forms a heat-insulating and smoke-insulating seal, and has good fire resistance and moisture resistance, and does not contain toxic components such as asbestos. The main technical performance has reached the advanced level of similar foreign products. The fire-resistant package can be effectively used for fire-proof sealing of cable penetration holes in power plants, industrial and mining enterprises, high-r...
