Embodiment 1

[0042] The production process of the glass fiber reinforced plastic tile back provided by the present embodiment comprises the following steps:

[0043] (1) carbon fiber 15Kg is mixed with non-alkali glass fiber 20Kg, basalt fiber 5Kg and is placed in the lower mold in the mold with tile back shape after being mixed, closes mold on described lower mold loam cake;

[0044] (2) Add iron powder 10Kg, dioctyl phthalate 10Kg, T31 epoxy resin curing agent 4Kg, decabromodiphenyl ether 10Kg, RX-80 resin 2Kg, carbon black 16Kg and quartz powder 20Kg to the molten The slurry is formed in 95Kg of epoxy resin, and then the slurry is injected into the mold through the glue injection port of the upper mold, kept at 110 ° C for 6 minutes, and demoulded to obtain a semi-finished product;

[0045] (3) After the semi-finished product is polished and deburred, the fiberglass tile back is obtained.

Embodiment 2

[0047] The production process of the glass fiber reinforced plastic tile back provided by the present embodiment comprises the following steps:

[0048] (1) carbon fiber 20Kg is mixed with non-alkali glass fiber 10Kg, basalt fiber 10Kg and placed in the lower mold in the mold with tile back shape after being mixed, closes the upper mold on described lower mold loam cake;

[0049] (2) 12.5Kg of copper powder, 6Kg of diisodecyl phthalate, 8Kg of amine-105 epoxy resin curing agent, 15Kg of tetrabromobisphenol A, 4,4'-bismaleimide diphenyl Add 1Kg of methane, 20Kg of carbon black and 20Kg of moissanite powder into 80Kg of molten epoxy resin to form a slurry, then inject the slurry into the mold through the injection port of the upper mold, and keep warm at 150°C Curing for 4 minutes, demoulding to obtain a semi-finished product;

[0050] (3) After the semi-finished product is polished and deburred, the glass fiber reinforced plastic tile back is obtained.

Embodiment 3

Abstract

The invention provides a glass steel tile back and a production process thereof. The glass steel tile back is prepared from epoxy resin, carbon fiber, glass fiber, basalt fiber, metal powder, a plasticizer, a curing agent, a flame retardant, a tackifier and packing. Due to reasonable proportions of the specific raw materials, the tensile strength of the tile back can be increased to 550-600MPa from conventional 370-500MPa, so that bent parts of the tile back can be effectively prevented from cracking, and the security of the tile back in the brake process is ensured; in addition, the glass steel tile back provided by the invention is excellent in corrosion resistance and high temperature resistance, a surface treatment procedure of the tile back can be avoided in actual production of a brake tile, the production efficiency can be improved, the applicable environment of the brake tile can be widened, and the service life of the brake tile can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of railway transportation equipment, and in particular relates to a glass steel tile back and a production process thereof. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, rail transit has gradually developed into my country's important infrastructure, the main artery of the national economy and the preferred tool for people to travel. The development of modernization has made my country's railway industry develop by leaps and bounds. [0003] In the actual operation of urban rail vehicles, a good and stable braking system is the guarantee for their safe operation. Due to the continuous improvement of the running speed of urban rail vehicles, the braking load of the train is greatly increased, which also puts forward higher requirements for the braking system of the train. The brake shoe is one of the important parts of the...
