Problems solved by technology

However, due to the poor weather resistance of diene-based unsaturated rubber, that is, it is difficult to resist the erosion and aging of ultraviolet rays, heat, oxygen and ozone, etc., so the wiper film of this material has the disadvantage of short service life.
In order to overcome the shortcomings of diene rubber in aging resistance and weather resistance, the second generation uses EPDM rubber as the main raw material for wiper blades. Although the aging resistance and weather resistance of this material have been improved, but The surface of this type of wiper blade is not easy to handle and has poor smoothness, so it has the disadvantage of poor wiping effect
This wiper film material uses methyl vinyl silicone rubber instead of natural rubber or a combination of natural rubber and other synthetic rubber in the existing formula, and adds fumed silica N20 as a reinforcing agent, combined with hydroxyl silicone oil for gas phase method The structure of silica N20 is controlled to improve the weather resistance, strength and hydrophobicity of the rubber compound. Although the weather resistance of this wiper rubber strip has been greatly improved compared with diene rubber wiper rubber strips, But its scrubbing effect is not good

Abstract

The invention discloses a preparation material of a scratch-resistant screen wiper rubber sheet, which is prepared from the following components in parts by weight: 40-90 parts of natural rubber, 20-50 parts of epoxidated trans-1,4-polyisoprene, 2-10 parts of vinyl silane coupling agent, 1-8 parts of polystyrene-polyethylene-butylene-polystyrene, 1-3 parts of processing assistant, 1-3 parts of zinc oxide, 5-20 parts of silica white, 2-5 parts of vulcanizing agent, 1-3 parts of vulcanization accelerator and 1-2 parts of anti-aging agent. The screen wiper rubber sheet prepared by the preparation material and preparation method has the characteristics of long service life and favorable wiping effect.

Description

technical field [0001] The invention belongs to the field of automobiles, and relates to an automobile wiper film, in particular to a preparation material and a preparation method of a scratch-resistant wiper film. Background technique [0002] The car wiper is a safety component used on the front and rear windows of the car windshield. Its working purpose is to remove water, ice, snow and dust on the glass surface to obtain a clear view. Car wipers are generally composed of four accessories: wiper film, boneless wiper steel sheet, wiper sheath and plastic parts. Among them, the wiper film is the part that actually effectively scrapes rainwater and other dirt on the outer surface of the car windshield. Therefore, the wiper The quality of the film performance directly affects the brushing effect. [0003] According to the raw materials used in the production of wiper film, its development can be divided into several generations. The first generation is mainly made of diene ...
