Embodiment 1

[0026] A pantograph carbon sliding plate, which sequentially includes an aluminum bracket, a bonding layer and a carbon strip. The raw materials for forming the bonding layer are composed of: phenolic epoxy resin 40g, dicyclopentadiene phenol epoxy resin 20g, 2 -16g of methyl-4-ethylimidazole, 55g of 200 mesh copper powder, and 7g of 30 mesh copper powder.

[0027] First, melt and blend the novolac epoxy resin and dicyclopentadiene phenol epoxy resin, and stir until they are uniform for later use; mix the aforementioned mixed resin with 2-methyl-4-ethylimidazole and copper powder evenly before use. Binder.

[0028] After coating the adhesive on the aluminum bracket, the carbon strip is adhered and cured at 70° C. to form a pantograph carbon sliding plate.

Embodiment 2

[0030] A pantograph carbon sliding plate, which in turn includes an aluminum bracket, a bonding layer and a carbon strip. The raw materials for forming the bonding layer are composed of 70 g of phenolic epoxy resin and 13 g of dicyclopentadiene phenol epoxy resin. -10 g of methyl-4-ethylimidazole, 35 g of 150 mesh copper powder, and 6 g of 35 mesh copper powder.

[0031] First, melt and blend the novolac epoxy resin and dicyclopentadiene phenol epoxy resin, and stir until they are uniform for later use; mix the aforementioned mixed resin with 2-methyl-4-ethylimidazole and copper powder evenly before use. Binder. After coating the adhesive on the aluminum bracket, the carbon strip is adhered and cured at 80° C. to form a pantograph carbon sliding plate.

Embodiment 3

[0033] A pantograph carbon slide plate, which sequentially includes an aluminum bracket, a bonding layer and a carbon strip. The raw materials for forming the bonding layer are composed of 50 g of phenolic epoxy resin, 10 g of dicyclopentadiene phenol epoxy resin, and 2 -Methyl-4-ethylimidazole 14g, 100 mesh copper powder 60g, 40 mesh copper powder 8g.

[0034] First, melt and blend the novolac epoxy resin and dicyclopentadiene phenol epoxy resin, and stir until they are uniform for later use; mix the aforementioned mixed resin with 2-methyl-4-ethylimidazole and copper powder evenly before use. Binder.

[0035] After coating the adhesive on the aluminum bracket, the carbon strip is adhered and cured at 90° C. to form a pantograph carbon sliding plate.

Abstract

The invention provides a pantograph carbon sliding plate. The pantograph carbon sliding plate comprises a metal bracket, a carbon strip and an adhesive layer; an adhesive for forming the adhesive layer comprises the following components in parts by weight: 40-70 parts of phenol formaldehyde epoxy resin, 10-16 parts of 2-methyl-4-ethylimidazole and 35-70 parts of copper powder. A curing temperaturedoes not exceed 90 DEG C, when products with different elongations adhere, deformation difference caused by difference of the elongations is reduced, therefore, adhesion strength is improved, and problems of carbon strip breakage, dropping and the like due to deformation of different materials are reduced.

Description

Technical field [0001] The invention relates to the field of important parts of vehicles, in particular to a pantograph carbon sliding plate. Background technique [0002] Carbon skateboards are important components of electric locomotives, electric trains, light rails, subways, etc., which directly contact the contact wire and belong to the category of sliding contact contact materials. The carbon strip is bonded to the pantograph by conductive adhesive to form a pantograph carbon sliding plate (referred to as carbon sliding plate). The pantograph carbon sliding plate and the contact wire form a pair of special friction pairs coupled mechanically and electrically. Electricity is obtained on the wire of the catenary to supply electricity to the locomotive. [0003] The pantograph carbon slide plate has the following characteristics in the working process: (1) Periodically and randomly changing load; (2) Strong current passes through during contact, which generates high heat; (3) H...
