Flame retardant rubber windshield rubber part and preparation method thereof

Abstract

The invention relates to a flame retardant rubber windshield rubber part and a preparation method thereof; the rubber part consists of the following raw materials in parts by weight: 90-120 parts of natural rubber, 50-70 parts of butadiene rubber, 55-62 parts of recycled rubber, 32-45 parts of aromatic polyamide fibers, 15-20 parts of zinc oxide, 5-8 parts of paraffin, 35-43 parts of high wear resistant carbon black, 5-8 parts of a plasticizer, 6-9 parts of sulfur, 43-50 parts of a calcium powder, 3-6 parts of a vulcanizing agent, 1.5-3 parts of an accelerator CZ, 2-5 parts of an anti-aging agent, 3.5-6 parts of a composite flame retardant, and 2-4 parts of rubber oil. The rubber windshield rubber part has reasonable formula, and has good sound-insulation, flame-retardant and windproof performance; the aromatic polyamide fibers added in the raw materials increase the rubber windshield strength; a prepared rubber windshield for railway passenger and goods cars has the advantages of flame retardancy, safety, reliability, small wear, and tight contact, can prevent dust, rain and snow from entering the cars, and has the advantages of wide adaptive environment temperature and long service life.

Description

technical field [0001] The invention belongs to the field of rubber materials, and in particular relates to a flame-retardant rubber windshield rubber part and a preparation method thereof. Background technique [0002] The windshield is a traditional Chinese medicine component of a railway passenger car. It is set at both ends of the carriage and is the passage for passengers from one carriage to another. In the relative position, the windshield should be in close contact. In the past, iron windshields have been used in my country. Iron windshields are not only noisy, but also have serious wear and corrosion. [0003] A new generation of rubber products suitable for China's national conditions developed to replace iron windshields. In January 1992, this product passed the scientific and technological achievements appraisal of the Ministry of Railways. In 1995, it won the third prize of the Ministry of Railways Science and Technology Progress Award. The rubber windshield h...
