Description

Technical Field

[0001] The invention relates to the field of composite material preparation, and in particular to an integrated pultrusion molding method and a preparation system for a composite material evacuation platform with vertical ribs. Background Art

[0002] With the development of my country's economy and urban construction, the subway has gradually become an effective way to solve these urban traffic problems with its advantages such as speed and comfort.

[0003] In order to quickly and orderly evacuate passengers from the section tunnel in special circumstances, and eliminate or reduce casualties caused by blocked evacuation passages, an evacuation platform leading to the station is installed on the side wall of the section tunnel. The installation height of the platform is consistent with the height of the station platform. In the event of an accident, the doors can be opened immediately to organize passengers to evacuate to a safe place. In special circumstances, passenger evacuation often results in crowding and running, which causes a great impact on the transport platform, making the evacuation platform bear a great force. Therefore, the transport platform must have sufficient structural strength, stability and fire resistance.

[0004] Patent 202111258607.6 discloses a method for preparing an integral composite material evacuation platform for a subway tunnel. An integral composite material evacuation platform for a subway tunnel is obtained by one-piece molding. The interior is filled with fireproof materials arranged at intervals. Two adjacent fireproof materials are provided with supporting ribs. The integral composite material evacuation platform for a subway tunnel eliminates the assembly process, avoids height differences during splicing, and makes the surface of the evacuation platform flat. At the same time, due to the filling of fireproof materials, it has better fire resistance. However, it was found during the preparation process that compared with the composite material board without fireproof material filling, the preparation of an evacuation platform with fireproof material and ribs, under the same production efficiency, the ribs are not completely cured, the strength is insufficient, and the overall performance is reduced. It is necessary to reduce the production speed, thereby extending the curing time. If the internal ribs are to be cured, the production speed needs to be reduced by 3-4 times, which has high energy consumption and is not conducive to mass production. At the same time, due to the long-term exposure of the outer panel to a high temperature environment, the strength of the outer panel will also decrease.

[0005] Therefore, in view of the above problems, the present invention urgently needs to provide an integrated pultrusion molding method and a preparation system for a composite material evacuation platform with vertical ribs. Summary of the invention

It is necessary to reduce the production speed to extend the curing time. To ensure the curing of the internal vertical ribs, the production speed needs to be reduced by 3-4 times, the energy consumption is high, and it is not conducive to mass production. At the same time, since the outer panel is in a high temperature environment for a long time, the strength of the outer panel will also be reduced.

[0113] Embodiment 5

[0114] like Figure 1 As shown, the present invention also provides a preparation system for a composite material evacuation platform with vertical ribs, comprising:

[0115] A plurality of fiber rollers 1 wound with fibers;

[0116] A plurality of fiber fabric rolls 2 with fiber fabrics wound thereon;

[0117] A first impregnation tank 3, used for storing an impregnation liquid A in the integrated pultrusion molding method of a composite material evacuation platform with vertical ribs as described in any one of the above;

[0118] A second impregnation tank 4, used for storing the impregnation liquid B in the integrated pultrusion molding method of the composite material evacuation platform with vertical ribs as described in any one of the above;

[0119] A conveying device 5, used for conveying the fireproof filling block to the high temperature curing device;

[0125] Comparative Example 1

[0126] The only difference between this comparative example and Example 1 is that no phenolic resin curing agent is added to the impregnation liquid B.

[0127] The physical properties of the composite evacuation platform with vertical ribs are shown in Table 1.

[0128] Comparative Example 2

[0129] The difference between this comparative example and Example 1 lies in the setting of the high-temperature curing temperature. The high-temperature curing temperature of this comparative example is directly raised to 230-270° C. and kept warm for 5-10 hours.

[0130] The physical properties of the composite evacuation platform with vertical ribs are shown in Table 1.

[0131] Comparative Example 3

[0132] The only difference between this embodiment and the first embodiment is that the mass ratio of the medium and low temperature curing agent to the solvent is 1:1.

[0133] Comparative Example 4

[0134] The difference between this embodiment and the first embodiment is that the mass ratio of the medium and low temperature curing agent to the solvent is 1:4.

[0135] Table 1 Physical properties of composite evacuation platform with ribs .

[0136] Compared with Example 1, since the vertical ribs and the outer panel fibers use the same impregnation liquid, at the same temperature, the fireproof filling block reduces the heat transfer toward the inner ribs due to its insulation property. After the composite material evacuation platform with vertical ribs is formed, the vertical ribs cannot be formed due to insufficient heat, resulting in a decrease in compressive strength and failure to meet application conditions.

[0137] Compared with Example 1, in the high-temperature curing process, curing at the same temperature in Comparative Example 2 will result in too fast a heating speed, rapid curing of the vertical ribs and the outer panel surface, and the inability of heat to be transferred to the interior, resulting in a decrease in the compressive strength and failure to meet the application conditions.

[0138] Compared with Example 1, the ratio of medium and low temperature curing agent and solvent in Comparative Examples 3 and 4 has a great influence on the strength of the later ribs. Too much solvent or too little solvent will affect the later compression strength and cannot meet the application conditions.

[0139] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
