Problems solved by technology

[0002] The fishplate (track joint splint) is commonly known as the road splint, which acts as a connection at the track joint, and is generally formed of metal materials, but the insulating fishplate is made of insulating material, which has corrosion resistance, anti-rust, anti-ultraviolet, The advantages of non-conductivity and non-magnetic conduction, based on the above advantages, for some fishplates with special structures such as bulging fishplates, it is also hoped that they have the advantages of the above-mentioned ordinary insulating fishplates, but the bulging fishplates in the prior art The boards are almost all made of metal materials, so they do not have the above advantages. Therefore, there is an urgent need to develop a process for producing bulging fishplates with new materials that have the above advantages.

Embodiment 1

[0041] see figure 1 As shown, the embodiment of the present application provides a preparation process of a bulging fishplate, comprising the following steps:

[0042] Step 100, immerse the fiber reinforced material into the resin paste to complete the prepreg operation (note that the fiber reinforced material can be selected as glass fiber fabric or glass fiber filament, etc. Of course, the type and state of the fiber reinforced material are not limited to the above) ;

[0043] Step 200, aging the obtained fiber prepreg;

[0044] Step 300, cutting the cured fiber prepregs according to the preset size, laying up the cut fiber prepregs from top to bottom in sequence, and cold pressing the preforms;

[0045] Step 400, molding the cold-pressed preformed fiber prepreg to obtain a semi-finished bulging fishplate;

[0046] Step 500 , machining and spraying an insulating layer on the semi-finished product of the bulging fishplate to obtain a finished product of the bulging fishpla...

Embodiment 2

[0063] The embodiment of the present application also provides a system for preparing a swollen fishplate. The swollen fishplate preparation process described in the first embodiment above is used to produce a swollen fishplate. Therefore, it has all the beneficial technical effects of the system.

[0064] In this embodiment, preferably, the preparation system of the bulging fishplate includes: a prepreg device 1, a curing device, a first cutting device, a cold press preforming device, a molding device, a second cutting device and a spraying device, the above The device can especially be installed in a dust removal workshop with constant temperature and humidity to avoid the influence of dust and moisture in the external environment on the product and improve the quality and stability of the product; (not shown in the figure)

[0065] The above device can be used to complete the following operations, and then produce the required composite insulation bulging fishplate:

[0066...

Embodiment 3

[0098] The embodiment of the present application also provides a bulging fishplate, which is prepared based on the method for preparing the bulging fishplate described in the above-mentioned embodiment 1 and the preparation system for the bulging fishplate described in the second embodiment. Therefore, it has All beneficial technical effects of the method and the system.

[0099] In this embodiment, preferably, the bulging fishplate includes the following components by mass percentage: two-component polyurethane resin paste: 30%-45%, fiber reinforced material such as fiber braid: 65%-70%.

[0100] According to the above description, it can be seen that the bulging fishplate with the above composition content is added with fiber reinforced materials, which has high strength, strong dynamic impact resistance, and good toughness, but is light in weight, easy to install, and saves skylight resources. In addition, due to the addition of Resin makes the bulge fishplate also have agi...

Abstract

The invention relates to the technical field of rail transit, in particular to a preparation process and preparation system of a swelled fishplate and the swelled fishplate. The preparation process of the swelled fishplate comprises the following steps: immersing a fiber reinforced material into resin paste to obtain prepreg; curing the obtained fiber prepreg; cutting the cured fiber prepreg according to a preset size to obtain multiple pieces of fiber prepreg, sequentially laying the multiple pieces of fiber prepreg obtained after cutting from top to bottom, and carrying out cold pressing preforming; carrying out mold pressing on the fiber prepreg subjected to cold pressing preforming to obtain a semi-finished swelled fishplate; and machining the semi-finished swelled fishplate and spraying an insulating layer on the surface of the semi-finished swelled fishplate to obtain the finished swelled fishplate. The composite insulation swelled fishplate can be prepared by utilizing the process, due to addition of the fiber reinforced material, the fishplate has high strength and strong dynamic impact resistance, and in addition, due to addition of resin, the fishplate has the properties of aging resistance and corrosion resistance, long service life and wide use temperature range.
