Embodiment 1

[0021] The rubber composition for the floor cloth of the EMU is made of the following raw materials in parts by weight:

[0022]

[0023] Among them, the flame retardant is zinc borate, the reinforcing agent is white carbon black, the vulcanizing agent is sulfur S-80, the softening agent is dioctyl sebacate, and the active agent is zinc oxide.

[0024] The preparation method of floor cloth for EMU is as follows:

[0025] (1) Glue drying: the temperature of the rubber drying machine is controlled at 50-60°C, and the drying time is more than 48 hours. It is required to dry thoroughly inside and outside without sandwich. After the glue is baked, cut small triangle pieces for later use. The temperature when cutting is ≥35°C;

[0026] (2) Natural rubber refining: In the double-roller plastic refining machine, the temperature of the front roller is 45-50°C, the temperature of the rear roller is 45-55°C, the distance between the rollers is 0.5-1mm, the refining time is 15min, and ...

Embodiment 2

[0032] The rubber composition for the floor cloth of the EMU is made of the following raw materials in parts by weight:

[0033]

[0034] Among them, the flame retardant is zinc borate, the reinforcing agent is white carbon black, the vulcanizing agent is sulfur S-80, the softening agent is dioctyl sebacate, and the active agent is zinc oxide.

[0035] The preparation method of the floor cloth for the EMU is the same as in Example 1.

Embodiment 3

[0037] A floor cloth for multiple train sets, which is made by using the rubber compound composition for floor cloth for multiple train sets in Example 2 as a raw material and by the preparation method in Example 2.

[0038] The test result of the motor train set floor cloth of the attached embodiment 3 is further explained to the motor train set floor cloth of the present invention:

[0039]

[0040] From the above test results, it can be seen that the floor cloth for EMUs of the present invention has excellent flame retardant performance, is environmentally friendly and harmless, and has good aging resistance and stability.

Abstract

The invention discloses a rubber material composition for floor cloth of a motor train set and the floor cloth, prepared from the rubber material composition, of the motor train set, and relates to the technical field of synthetic rubber. The rubber material composition is prepared from the following raw materials of: in parts by weight, 45-50 parts of natural rubber, 10-15 parts of nitrile rubber, 10-18 parts of flame retardant, 10-20 parts of a reinforcing agent, 1-2 parts of a vulcanizing agent, 3-6 parts of a softener and 3-5 parts of an active agent. Through adoption of the natural rubberand nitrile rubber as main materials, the product has good elasticity, can relieve an impact force, and has large surface resistance and a good anti-skid effect, and the travelling safety of passengers can be ensured effectively; since the other selected materials are environment-friendly materials, pollution-free and recyclable, requirements of people for environment-friendly decoration of the motor train set can be met, and environmental protection requirements can be met during processing production and application.

Description

technical field [0001] The invention relates to the technical field of synthetic rubber, in particular to a floor cloth rubber composition for a train set and the prepared floor cloth for a train set. Background technique [0002] Floor cloth for EMUs is not only for decoration, but also to ensure the personal safety and health of passengers. Therefore, it includes not only physical and mechanical performance requirements, but also flame retardant and environmental protection performance requirements. The existing domestic EMU floor cloth usually uses synthetic rubber as raw material, which has low surface resistance, poor anti-skid performance, and is not environmentally friendly. [0003] In order to improve the international competitiveness of Chinese enterprises, adopt an independent technology system suitable for national conditions and road conditions, learn from others, learn from, digest, absorb, and combine internationally advanced, mature, and reliable technologie...
