Description

Technical Field

[0001] The utility model relates to the technical field of arc-proof fabrics, in particular to an aerogel composite arc-proof fabric. Background Art

[0002] The development of arc-proof fabrics has been a topic of great concern in the textile industry in recent years. With the acceleration of industrialization and the improvement of labor safety awareness, the demand for protective clothing materials has become more and more urgent. Technically, arc-proof fabrics have undergone many improvements and upgrades. In the market, the demand for protective clothing has shown an upward trend. Especially in the fields of aerospace, military equipment manufacturing, energy mining, etc., the safety requirements for employees are extremely high. Therefore, arc-proof fabrics have gradually been widely accepted and applied as an important personal protective equipment.

[0003] However, it still has the following disadvantages in actual use:

[0004] The more mature arc-proof materials on the market are all made of single-layer or double-layer intrinsic flame-retardant materials, such as aramid 3A, acrylic cotton, etc. The arc-proof test has strict restrictions on gram weight, and it is difficult to achieve a good ATPV value with a lower gram weight.

[0005] Therefore, a new aerogel composite arc-proof fabric is proposed to solve the above problems. Utility Model Content

[0006] Technical issues to be solved

[0007] The purpose of the utility model is to provide an aerogel composite arc-proof fabric, which is used to solve the problem that the more mature arc-proof materials on the market are all made of single-layer or double-layer intrinsic flame-retardant materials as raw materials, such as aramid 3A, nitrile cotton, etc., through the cooperation of the flame-retardant high-strength layer, the aerogel foam layer and the antibacterial skin-friendly lining layer. The arc-proof test has strict restrictions on gram weight, and it is difficult to achieve a good ATPV value with a lower gram weight.

[0008] Technical Solution

[0009] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0010] The utility model discloses an aerogel composite arc-proof fabric, comprising:

[0011] The main body of the fabric includes a flame-retardant high-strength layer, an aerogel foam layer, and an antibacterial skin-friendly lining layer which are laminated in sequence from top to bottom.

[0012] Furthermore, the flame retardant high-strength layer is made of woven ring spinning, and the fabric style is plain weave;

[0013] Specifically, the flame retardant high-strength layer has good strength and can effectively ensure the thermal insulation performance of the aerogel foam layer under arc impact. Moreover, through the weaving method, a higher density can be ensured to increase the thermal insulation performance.

[0014] Furthermore, the aerogel material in the aerogel foam layer is silicon dioxide aerogel;

[0015] Specifically, the aerogel composite foam material of Nano Technology can be preferably selected, which has the characteristics of low thermal resistivity, stable product process without powder falling, softness, lightness and low weight;

[0016] Aerogel is a material with a micro-nano three-dimensional porous structure. It is light and has good thermal insulation properties, but its disadvantage is that it is brittle and easily catalytic, which limits its application in many fields. At present, in China, some relatively excellent products have emerged for the cross-border application of aerogel. For example, the aerogel composite felt and aerogel composite foam produced by Nano Technology attach and wrap aerogel powder on a large area of ​​PE foam substrate, so that the thermal insulation performance of aerogel can be transferred to the PE foam substrate that is not easily catalyzed, thus eliminating the weak and retaining the strong.

[0017] Furthermore, the antibacterial skin-friendly lining layer is impregnated with an antibacterial auxiliary agent;

[0018] Specifically, the antibacterial and skin-friendly lining layer has a light weight, and after being impregnated with an antibacterial additive, it has a lasting antibacterial effect, is more skin-friendly and more hygienic.

[0019] Furthermore, the fabric body adopts a hot melt adhesive powder dot coating composite process to composite the flame retardant high-strength layer, the aerogel foam layer, and the antibacterial skin-friendly lining layer;

[0020] Specifically, the lattice of this process can reduce the pressure of the flame-retardant high-strength layer and the antibacterial skin-friendly lining layer on the aerogel foam layer, thereby alleviating the problem of reduced voids in the aerogel composite foam after compounding to the greatest extent.

[0021] Beneficial Effects

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] 1. The utility model, by providing an aerogel foam layer and a flame retardant high-strength layer, can make the APTV value higher and safer under the same gram weight thanks to the lightweight heat insulation performance of the aerogel foam, while having a flame retardant effect.

[0024] 2. Based on beneficial effect 1, by providing an antibacterial and skin-friendly lining layer, the fabric can be made more skin-friendly and comfortable during wearing, and at the same time, the main body of the fabric can have an antibacterial function.
