Abstract

The invention discloses a rubber material for processing an automobile wiper blade, and belongs to the technical field of automobile parts. The rubber material is prepared from, by weight, 60-65 parts of nitrile butadiene rubber, 15-20 parts of ethylene-propylene-diene monomer rubber, 15-20 parts of polyacrylic acid, 10-15 parts of coal gangue powder, 8-12 parts of sea-foam stone powder, 6-10 parts of hydrogenated rosin, 6-10 parts of dimethicone, 5-8 parts of polyethylene wax, 4-6 parts of sulfated castor oil, 4-6 parts of bonding agent, 3-5 parts of trioctyl citrate, 2-4 parts of oleamide, 1-2 parts of magnesium hydrate and 0.1-0.2 part of rare earth. The rubber material has excellent abrasive resistance and excellent weather resistance, the service life is long, the glass attaching performance is good, glass can not be scratched in use, and functionality is high. As the bonding agent is added, the bonding performance of raw materials can be further improved, and rubber mixing and vulcanizing are convenient.

Description

Technical field: [0001] The invention relates to the technical field of automobile parts, in particular to a rubber material for processing automobile wiper blades. Background technique: [0002] The wiper blade is a commonly used body accessory for automobiles. It is mainly used to scrape off the rain on the windshield in rainy days, and is also used to wash the windshield. The power source of the wiper blade comes from the electric motor, which is the core of the entire wiper blade system. There are roughly two types of wiper blades, one is the traditional intermittent type, which is the most common type of wiper blade, and is adjusted by the driver according to the rain and sight conditions; the other is the raindrop sensor type, which is mostly used in On mid-to-high-end models. A good wiper blade must have the characteristics of heat resistance, cold resistance, acid and alkali resistance, corrosion resistance, fit the windshield, reduce the load on the motor, low noi...
