Abstract

The invention provides a small-resistance base plate and a production method thereof, and the production method comprises the following steps: S1, carrying out two-stage surface treatment on an antifriction plate to form an active bonding surface of the antifriction plate; S2, brushing an adhesive on the active bonding surface to form an adhesive layer; and S3, after the adhesive is dried, placing a rubber material on the side face, away from the antifriction plate, of the adhesive layer, vulcanizing the antifriction plate, the adhesive and the rubber material integrally, and preparing the small-resistance base plate; the two-stage surface treatment process comprises a mechanical surface treatment process and a surface activation treatment process which are sequentially carried out; according to the small-resistance base plate and the production method thereof, the antifriction plate is subjected to two-stage surface treatment, and the antifriction plate, the adhesive and the rubber material are integrally vulcanized, so that the bonding strength of the small-resistance base plate is enhanced, and the vulcanization production process of the rubber plate and the bonding process of the antifriction plate are combined into a whole; and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of rail fasteners, in particular to a small resistance backing plate and a production method thereof. Background technique [0002] At present, in the field of rail transit technology, when the temperature span of the area where the railway bridge is located is large, in order to reduce the interaction force between the bridge structure and the welded long steel rail on the bridge, the longitudinal resistance of the rail provided by the rail fastener is required to be small. To meet this requirement, small-resistance fasteners are often used in track elevated lines. When the rail moves within a certain range, the small-resistance fastener allows the rail to move, thereby releasing the interaction force between the bridge and the rail. [0003] In the prior art, reducing the longitudinal resistance of the fastener can be achieved by reducing the fastening force of the fastener and reducing the friction coeffi...
