Rubber gasket for track traffic and manufacturing method thereof

Abstract

The invention belongs to the technical field of damping material, and relates to a rubber gasket for track traffic and the manufacturing method thereof. The invention provides the rubber gasket for track traffic, which comprises a flat plate (1) used as a base, and a plurality of studs (2) positioned on the flat plate (1); the flat plate (1) is formed by the composition of rubber layers and at least one fiber enhancement layer; both the upper surface and the lower surface of the fiber enhancement layer are provided with the rubber layers; the fiber enhancement layer is made of fiber cloth with densely distributed meshes; the rubber layer on the upper surface of the fiber enhancement layer penetrates the meshes on the fiber enhancement layer and is combined with the rubber layer on the lower surface of the fiber enhancement layer; and the rubber layer on the lower surface of the fiber enhancement layer penetrates through the meshes on the fiber enhancement layer and is combined with the rubber layer on the upper surface of the fiber enhancement layer. According to the invention, the adhesive strength of the rubber layers and the fiber enhancement layer is enhanced, the vibration isolating effect of the rubber gasket is ensured, the safety is enhanced, and the problems of vibration and noses in a subway can be solved.

Description

technical field [0001] The invention belongs to the technical field of damping materials, and in particular relates to a rubber pad for rail transit and a manufacturing method thereof. Background technique [0002] With the rapid development of urban rail transit and the improvement of people's awareness of environmental protection, the noise pollution of rail transit has become a hot spot of concern, and has been highly valued by the relevant state departments. For this reason, many road conditions of urban rail transit require vibration reduction treatment. In recent years, rubber pads with low cost, simple construction technology and good shock absorption effect will be more and more recognized in special sections of urban rail transit. [0003] Due to the requirement of service performance, the existing rubber pads need to use skeleton materials such as fiber reinforced layers such as cords and canvases. In order to give full play to the role of these skeleton material...

AI Technical Summary

Problems solved by technology

In order to combine the rubber layer and the braided cloth layer into a whole, a layer of rubber coating is added between the damping layer and the braided cloth layer, the braided cloth layer and the interlayer, the braided cloth layer and the covering layer; the rubber coating is made of Latex or solvent glue of dilute concentration directly applies glue to the skeleton material of the woven cloth layer to treat the skeleton material. From the perspective of environmental protection, this may cause pollution to the environment due to the use of solvents to a certain extent.

In addition, in order to increase the combination of the rubber layer and the skeleton material, multiple dipping and glue coating methods are required, and the production process is cumbersome.

At the same time, if the dipping and gluing treatment is not uniform, there may be cracking problems due to the weak combination of the rubber layer and the fiber reinforced layer during use, which will affect the product life.
