Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] see figure 1 , and combined with figure 2 and image 3 Shown, the preparation method of a kind of insulating composite material splint of the present invention comprises the following steps:

[0026] Step S1, using reinforced fibers as raw materials, forming reinforced fiber filaments with a diameter of 1mm-2mm by kneading, and the raw materials of reinforced fiber filaments are one or more of glass fibers, basalt fibers, carbon fibers, or mixed fibers;

[0027] Step S2, pour the resin and additives into the glue mixing tank and stir evenly, then add polymerization inhibitor, mold release agent, crosslinking agent, curing agent, viscosity reducer and auxiliary a...

Abstract

The invention discloses a preparation method of an insulation composite material rail clamping plate. According to the preparation method, reinforced fibers are used as raw materials, the reinforced fibers are twisted to reinforced fiber filaments, the surfaces of the reinforcing fiber filaments are soaked to form reinforced fiber filament prepregs, the reinforced fiber filament prepregs are usedfor warp and weft weaving to form a layered structure with penetrating holes on the surface, the reinforced fiber filaments penetrate into the penetrating holes to form a block structure, and then a mold is used for compression molding. According to the preparation method, due to the fact that the reinforced fiber filaments are arranged in three dimensions in the raw materials adopted by the railclamping plate, therefore, in the compression molding process, no matter in which direction the rail clamping plate is stressed, the whole stress effect of the rail clamping plate can be improved dueto the effect of the reinforced fiber filaments. According to the method ,a product is light in weight and high in strength, the product is of an integrated structure, the transportation and installation are convenient, the product has corrosion resistance, the workload of maintenance and replacement is greatly reduced to a certain extent, the good insulating property can avoid the problem of short circuit of a track circuit caused by scrap iron scattered by friction between train wheels and a steel rail, the correct transmission of a track circuit signal is guaranteed, and the driving safetyof a railway is guaranteed.

Description

technical field [0001] The invention relates to the technical field of railway rail fitting processing, and more specifically, to a method for preparing an insulating composite rail splint. Background technique [0002] The splint at the track joint is commonly known as the splint, and it acts as a connection at the track joint. However, the track splint at the railway station interval not only needs its function of connecting the track but also needs to ensure good insulation performance. This is because there are track circuits at both ends of the track, which are used to monitor the occupancy and departure of the train on the line of the section or station, and directly provide the train with the position of the forward train required for operation, the signal display in front of the operation and the line conditions, etc. Information, once the circuits at both ends of the track are short-circuited or connected, unpredictable consequences will occur. At present, most of...
