Rubber floor cloth composition, rubber floor cloth prepared from rubber floor cloth composition and applications of rubber floor cloth composition and rubber floor cloth

Abstract

The invention provides a rubber floor cloth composition for preparation of rubber floor cloth. The composition is prepared from, by weight, 50-70 parts of EPDM (ethylene propylene diene monomer) rubber, 30-50 parts of POE (polyolefin elastomer), 2-8 parts of BIPB (Bis(tert-butylperoxy Isopropyl)benzene), 120-170 parts of silane modified magnesium hydrate, 20-50 parts of expanded vermiculite and 20-40 parts of silane modified white carbon black, wherein the sum of weight parts of the EPDM and the POE is 100. The invention further provides application of the composition to preparation of the rubber floor cloth, a preparation method of the rubber floor cloth with the composition serving as a raw material and application of the rubber floor cloth to railway vehicles. The rubber floor cloth has advantages of thickness uniformity, high strength, low volatile matter content, nontoxicity, safety and the like.

Description

technical field [0001] The invention belongs to the field of synthetic rubber, and in particular relates to a rubber floor cloth composition and the prepared rubber floor cloth and its application in rail transit vehicles. Background technique [0002] Rail transit vehicles, including railway passenger cars (including railway high-speed passenger car EMUs, ordinary railway passenger cars), light rail, trams, subway vehicles, etc., use rubber floor coverings not only for decoration, but also to ensure the personal safety and health of passengers. Therefore, the requirements for the above-mentioned rail transit floor cloth include not only physical and mechanical properties, but also flame-retardant and environmental protection properties. For example, the statutory standard NF F31-812 "Railway Rolling Stock Rubber Floor Coverings" stipulates that rubber floor coverings for high-speed railway passenger cars and light rail subway vehicles must meet the following requirements: ...

AI Technical Summary

Problems solved by technology

[0012] 1) The dispersion of materials during mixing is uneven, and the results of product performance tests are quite different;

[0013] 2) There will be situations where the interior of the floor cloth is not dense and there are air bubbles, and the surface will be uneven and occasionally scratched, which will affect the product quality;

[0014] 3) The thickness of the product does not meet the requirements

The laminated products are prone to problems such as bubbling during use

[0015] 4) It is difficult to achieve continuous production in calendering, and problems such as obvious joints are prone to occur, which affects product quality and appearance

[0016] 5) More production personnel are required, the efficiency is low, and the energy consumption is large
