Detailed Description

Before the present invention is described in detail, it should be noted that in the following description, like elements are represented by like reference numerals.

Referring to fig. 1 to 3, a first embodiment of the fire-retardant layer of the present invention is suitable for application to a fire-retardant product, such as, but not limited to, a fire-retardant plate, a partition curtain, a fire-retardant coat worn by a fire fighter, etc. in a building structure. The fire-proof layer 100 includes a first fire-proof unit 1 and a second fire-proof unit 2. The first fireproof unit 1 includes two first substrates 11 opposite to each other at an interval, and the first substrates 11 together define an accommodating space 12. Each first base layer 11 has an inner side 111 facing the accommodating space 12, and an outer side 112 opposite to the inner side 111. The material of the first base layer 11 may be, for example, a fire-proof cloth, and the fire-proof cloth may be woven by a yarn with high temperature resistance and flame retardant properties, or may be woven by a post-treatment method to have the high temperature resistance and flame retardant properties.

The second fire protection unit 2 is disposed in the accommodating space 12, and includes a plurality of channel structures 21 arranged along a first direction D1, and a fire protection material 22. The channel structure 21 is connected to the inner side 111 of the first substrate 11. In the present embodiment, each channel structure 21 is tubular and defines a channel space 211, and the channel space 211 extends along a second direction D2 perpendicular to the first direction D1. The material of the channel structure 21 may be glass fiber or other high temperature resistant materials. The fireproof material 22 is filled in the channel space 211 of the channel structure 21. The fire-proof material 22 includes a water-absorbing material 221 and a first sintering material 222a and a second sintering material 222b that can be heated to form a sintered structure 223 (see fig. 4). The water absorbing material 221, the first sintered material 222a, and the second sintered material 222b are mixed and filled in the channel space 211 in the channel structure 21. In this embodiment, the water absorbing material 221 is a particulate water absorbing polymer, such as Super Absorbent Polymers (SAP), and is kept dry at ordinary times to reduce the weight of the fire-retardant layer 100, and when a fire occurs, it can immediately absorb external moisture and swell to form a gel state. A suitable space can be reserved between the channel structure 21 and the water-absorbing material 221 for the water-absorbing polymer to expand and accommodate after absorbing water. In this embodiment, the basic components of the first sintering material 222a and the second sintering material 222b may be ceramic materials (e.g., including alumina and silicic acid), and the ratio between the alumina and the silicic acid is adjusted such that the sintering temperature of the second sintering material 222b is higher than the sintering temperature of the first sintering material 222a, and the particle size and the particle weight of the second sintering material 222b are also larger than the first sintering material 222 a. In addition to the first sintering material 222a, the fireproof material 22 of the present invention may further include a high-temperature resistant material such as glass fiber or carbon fiber.

In a normal state without fire, the fire-retardant layer 100 is flat due to the flexible material of the channel structure 21, and the fire-retardant material 22 is in the form of powder or particles. When a fire occurs, by injecting water between the two first base layers 11 of the first fire protection element 1, after the injected water passes through the channel structure 21 and is absorbed by the water absorbent material 221, the water absorbent material 221 expands into a gel state, at this time, the channel structure 21 is expanded into a tubular shape due to the water absorbent material 221 absorbing water and expanding, the overall thickness of the fire protection layer body 100 is increased, and at this time, the first sintered material 222a and the second sintered material 222b are partially covered in the expanded water absorbent material 221 or partially still dispersed in the channel space 211. At this time, the first fire protection unit 1 is directly exposed to the outside to serve as a first fire protection structure of the whole fire protection layer 100, the channel structure 21 located between the two first base layers 11 of the first fire protection unit 1 serves as a second fire protection structure, the first sintering material 222a and the second sintering material 222b are filled in the channel space 211, the water absorbing material 221 serves as a third fire protection structure, and the water absorbed by the water absorbing material 221 also has a cooling effect.

With reference to fig. 4 to 6, the first sintering material 222a and the second sintering material 222b are used to ensure that, when the fire is continuously burning, due to the high temperature environment, the water in the water absorbing material 221 begins to evaporate to form water vapor and the first sintering material 222a with smaller particle size and smaller total amount of particles overflows, and when the water vapor reaches the side (outer side 112) of the first base layer 11 facing the fire, the escaped water vapor further evaporates due to high temperature, so that the first sintering material 222a stays on the first base layer 11 and begins to be sintered and distributed on the first base layer 11 due to high temperature, thereby integrally delaying the time that the first base layer 11 may be continuously burned due to high temperature. When the fire is still burning continuously, so that the temperature in the channel space 211 is gradually increased, or when the first substrate 11 and the tube wall of the channel structure 21 are burned successively, so that the channel space 211 directly faces the high temperature of the fire, at this time, the second sintering material 222b with a larger sintering temperature, a larger particle size and a larger weight is sintered and is sintered together with other materials such as carbon fiber, glass fiber and the like into another sintering structure 223a, and the effect of preventing the fire from continuing to expand inwards or delaying the expansion inwards can be exerted to a certain extent by the blocking of the another sintering structure 223 a. The second sintering material 222b may also comprise other materials that melt when exposed to high temperature, and the melting temperature of the material is preferably higher than the sintering temperature of the first sintering material 222a, thereby separating the sintering from the first sintering material 222a into multiple sinters at different temperatures and different time points.

Therefore, as mentioned above, in addition to the effects of stopping the fire and reducing the temperature layer by layer achieved by the first base layer 11, the channel structure 21 and the water absorbing material 221, the fire-proof material 22 is further disposed, so that the fire-proof material 22 is sintered to form a more one-layer fire-proof mechanism during the continuous combustion of the fire, and in addition to stopping the fire, the fire-proof layer 100 can also effectively prolong the time of stopping the fire.

Referring to fig. 7, the water absorbing material 221, the first sintering material 222a and the second sintering material 222b in each channel space 211 may also be coated and fixed by a plurality of water permeable layers 224 (for example, water soluble films made of PVA material may be used). When a fire disaster does not happen in a normal state, the moisture-proof effect can be effectively achieved through the arrangement of the water permeable layer 3. When water is charged into the channel structure 21 in the event of a fire, the water-permeable layer 224 is dissolved and the water absorbent material 221 absorbs water to swell.

Referring to fig. 8, a second embodiment of the fire-retardant layer 100 of the present invention is shown, and the second embodiment is substantially the same as the first embodiment, mainly different in the implementation structure of the second fire-retardant unit 2. In the second embodiment, the second fire-proof unit 2 further includes a water-soluble sheet 23 (for example, a water-soluble film made of PVA material may be used), and the channel structure 21 of the second embodiment has two opposite second base layers 212. The second base layer 212 is substantially a fire-proof cloth, and the fire-proof cloth can be a net-shaped glass fiber material, but the material is not limited as long as the effects of fire-proof and fire-retardant can be achieved. Each second base layer 212 has a plurality of strip-shaped bonding portions 212a arranged at intervals along a first direction D1 and bonded to the water-soluble sheet 23 by sewing or bonding, for example, and each bonding portion 212a of one of the second base layers 212 corresponds to each bonding portion 212a of the other of the second base layers 212, so that the second base layers 212 together form the channel structure 21. The water absorbing material 221, the first sintered material 222a, and the second sintered material 222b are bonded to the water-soluble sheet 23 by being embedded or fixed. By the arrangement of the water-soluble sheet, the water absorbing material 221, the first sintered material 222a, and the second sintered material 222b can be uniformly distributed in each channel structure 21. When a fire disaster does not occur in a normal state, the moisture-proof effect can be effectively achieved by arranging the water-soluble sheet 23. When water is filled in the channel structure 21 in the event of a fire, the water-soluble sheet 23 is dissolved and the water absorbent material 221 absorbs water to swell. The first sintering material 222a and the second sintering material 222b are sintered to form the sintering structures 223, 223a, as mentioned above, so as to improve the lifetime of the first fire protection unit 1 and the second fire protection unit 2.

In summary, the fire-proof layer 100 of the present invention not only delays the spread of fire and prolongs the life-saving time by the arrangement of the first base layer 11 and the second base layer 212, but also effectively reduces the temperature and has the same effect of delaying the spread of fire by the arrangement of the water-absorbing material 221, and in addition, by the arrangement of the first sintering material 222a and the second sintering material 222b, when the fire enters the fire-proof layer 100 gradually at high temperature, the sintering structures 223, 223a (see fig. 4 and 6) can be formed, so as to prolong the fire-proof layer 100 to block the fire, so that the fire-proof layer 100 can exert its fire-proof effect more, and thus the object of the present invention can be achieved.

However, the above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the contents of the specification of the present invention are still included in the scope of the present invention.
