Embodiment 1

[0026] 1. Ingredients: Preliminary mixing of fibers, mixing between layers

[0027] 1. The first step is to weigh according to the required ratio, and then to open. The advantage of opening is to disperse the fibers into single fibers, which is beneficial to the uniform dispersion of the fibers and improves the comprehensive technical index performance of the filter material;

[0028] 2. In the second step, the mass percentage of ceramic fiber is 30%; the mass percentage of ultra-fine glass fiber is 70%. ~170mm, the fibers are evenly distributed layer by layer during batching, and the raw materials after opening are layered and superimposed, the ultra-fine glass fiber is placed at the bottom, and then a layer of ceramic fiber is placed; stack 5 times in this order; Mode fiber dispersion is more uniform;

[0029] 3. After mixing the materials, directly take the materials up and down according to the number of layers, and put them into the unpacking machine;

Abstract

The invention discloses a fire-resisting blanket material and a manufacturing process thereof and belongs to the technical field of fire-resisting materials. The fire-resisting blanket material is characterized by being composed of base cloth and a superfine fiber filter surface layer over the base cloth, the base cloth is a superfine fiberglass mesh, the superfine fiber filter surface layer is a ceramic fiber and superfine fiberglass mixed layer, the mass percent of ceramic fiber is 20-45%, and the mass percent of superfine fiberglass is 55-80%. During manufacturing, raw materials are opened, stacked layer by layer, and then unpacked in a mixed mode, the superfine fiber filter surface layer is manufactured with the mechanical web forming technology, and then the superfine fiber filter surface layer is spread on the base cloth to obtain the fire-resisting blanket material. The fire-resisting blanket material is obtained through combination of two kinds of fiber, the problem that ceramic fiber is hard to comb is solved, and the fireproof grade is increased.

Description

technical field [0001] A fireproof felt material and its manufacturing process belong to the technical field of fireproof materials. Background technique [0002] Currently, known fireproof materials are generally made of glass fibers. The fire protection grade of this kind of fireproof material is poor. If it encounters high temperature, the breaking strength of the fireproof felt will drop rapidly, and it will degrade and age rapidly, resulting in damage and failure. Ceramic fibers are not easy to comb and have poor linking properties. During the carding process of the product, there will be problems with cylinder entanglement. As a result, the current ceramic fibers cannot be needled with the base fabric, and are easy to break and difficult to form a web. Therefore, in the traditional process, it is impossible to only form glass fibers and ceramic fibers together into felts, and it is necessary to add some other fibers (such as metal fibers) to change the toughness, so a...
