Problems solved by technology

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. The current domestic preparation methods cannot produce high-quality floor cloth for EMUs, which cannot meet the growing demands of people. Growing demand for environmentally friendly and safe materials

Embodiment 1

[0018] A preparation method of floor cloth for multiple trains, characterized in that the method includes the following steps:

[0019] (1) Glue baking: The temperature of the glue-drying machine is controlled at 50-60℃, and the glue-bake control time is more than 48h. It is required to be thoroughly baked inside and out without sandwiching. After the glue is baked, cut small triangles for use, and the temperature during cutting is ≥35℃;

[0020] (2) Natural rubber plasticizing: In the double-roller plastic mixing machine, the front roller temperature is 45-50℃, the rear roller temperature is 45-55℃, the roller distance is 0.5-1mm, and the plasticizing time is 15min. After the time is reached, the triangle bag is placed for 24h. -7d;

[0021] (3) Ingredients: Weigh 50 parts by weight of natural rubber, 15 parts by weight of nitrile rubber, 18 parts by weight of zinc borate, 20 parts by weight of white carbon black, 2 parts by weight of sulfur S-80, and 6 parts by weight of dioctyl se...

Abstract

The invention provides a preparation method for a floor cloth used by a motor-train set and belongs to the technical field of synthetic rubber. The method includes the following steps: (1) baking glue; (2) plasticating natural glue; (3) preparing material; (4) mixing the material; (5) adding a vulcanizing agent; (6) performing vulcanization. The prepared floor cloth used by motor-car groups has good elasticity, the impact force can be relieved, the surface resistance is large, the antiskid effect is good, the safety of passenger traveling can be effectively guaranteed the material has no pollution to the environment, has no halogen, the burning is low smoke and nontoxic mist, and is environmental protection, and the generated floor cloth used by motor-car groups has stable quality and highproduction efficiency.

Description

Technical field [0001] The invention relates to the technical field of synthetic rubber, in particular to a preparation method of floor cloth for EMUs. Background technique [0002] The floor cloth for EMUs is not only for decoration, but also to ensure the safety and health of passengers. Therefore, it includes both physical and mechanical performance requirements and flame-retardant environmental protection performance requirements. The existing domestic EMU floor cloths usually use synthetic rubber as the raw material, which has low surface resistance, poor anti-slip performance, and is not environmentally friendly. The current domestic preparation methods cannot produce high-quality EMU floor cloths, which cannot meet the increasing demands of people. Increasing demand for environmentally friendly and safe materials. [0003] In order to improve the international competitiveness of Chinese enterprises, adopt an independent technological system suitable for national conditions...
