preparation example Construction

[0027] A kind of preparation method of floor cloth for railway passenger car and EMU, described method step is as follows:

[0028] S1: According to the weight ratio of raw materials, the raw materials include high-styrene styrene-butadiene rubber, polyisoprene rubber, vulcanizing agent, flame retardant, filler, and protective agent;

[0029] S2: Put the high-styrene styrene-butadiene rubber and polyisoprene rubber into the internal mixer according to the weight ratio, add antioxidants, and carry out mixing and internal mixing at a temperature of 90-160 degrees Celsius, and open after 5-10 minutes. The bin gets the mixed material;

[0030] S3: According to the above proportioning weight, add in the mixing material obtained in S2, mix again, wait for 3-6 minutes, mix evenly, pour in the feed bin of extruder;

[0031] S4: Extrude the mixed material in S3 from the extruder, extrude the thickness, adjust the thickness according to the requirements, the unvulcanized sheet material...

Abstract

The invention discloses floor cloth for passenger trains and motor train units and a preparation method thereof. The floor cloth is prepared by using high styrene butadiene rubber and polyisoprene rubber together and adding a vulcanizing agent, a flame retardant, a filler and a protective agent through a dynamic non-pressure vulcanization technology. The floor cloth provided by the invention has no color change phenomenon and does not generate harmless substancesunder irradiation of ultraviolet rays, and is environment-friendly. The obtained floor cloth for passenger trains and motor train units is subjected to a physical performance test according to a conventional detection method, and results show that the hardness (Shore A) is 80-90, the tensile strength is 10 MPa, the elongation at break is 280%, the flame retardance is grade 1, the vertical deformation is 2.4, and the floor cloth is not discolored under illumination (the wavelength of ultraviolet light is 400).

Description

technical field [0001] The invention belongs to the technical field of floor cloths, and in particular relates to floor cloths for railway passenger cars and train sets and a preparation method thereof. Background technique [0002] The floor cloth of railway passenger cars can meet the decoration needs firstly, and the second is to ensure the personal safety and health of passengers; therefore, the floor layout used on railway passenger cars has relevant rigid requirements, including aging resistance, friction resistance and flame retardancy. [0003] The performance of the existing floor cloth can not achieve the desired effect. After a period of use, the color of the floor cloth will change, and various performances will be reduced. More importantly, the value rate of the existing floor cloth production process is not high, which is reflected in the high labor cost. consume energy. Contents of the invention [0004] The purpose of the present invention is to propose a ...
