Problems solved by technology

The rubber strip described in this invention has good tensile strength and elongation at break, but because it adopts natural rubber, it must add additives such as various sulfur-containing compounds and petroleum hydrocarbons in the preparation process, which not only It consumes a lot of petrochemical energy, and the rubber strips of this type of formula will emit harmful gases during the production process, which will cause great pollution to the environment; at the same time, it is difficult to dispose of rubber strips made of natural rubber, and toxic gases will be generated during incineration. Does not degrade, destroys soil ecology
In addition, the performance of wiper rubber strips made of natural rubber is insufficient in terms of high temperature resistance and cold resistance.

Abstract

The invention discloses a rubber material for windscreen wipers, a preparation method of the ionomer-metal composite artificial muscle, and a process for producing a windscreen wiper from the rubber material. The rubber material contains the following ingredients in parts by weight: 100 of methylvinylsilicone rubber, 20 to 55 of fumed silica N20, 1 to 2.5 of hydroxylsilicone oil, 5 to 10 of lubricants, 0 to 1.7 of colorants, and 0.8 to 2.5 of 2,4-dichlorobenzoyl peroxide. In the rubber material, methylvinylsilicone rubber replaces natural rubber or a composition of natural rubber and other synthetic rubber in the existing formula, the fumed silica N20 is used as reinforcing agent, the structure of fumed silica N20 is controlled by hydroxylsilicone oil, so that the high/low temperature resistance of the rubber material is improved an the strength of the rubber material is increased, and the rubber material is easier to be processed. The special lubricants are adopted to endow the rubber material with excellent hydrophobicity, which prevents water from being attached on the glass surface after cleaning the glass windscreen.

Description

technical field [0001] The invention relates to an automobile part, in particular to a rubber material for an automobile wiper rubber strip, a preparation method thereof and a process for preparing a windshield wiper rubber strip with the rubber material. Background technique [0002] The formula of the existing automobile wiper rubber strip is usually formed by mixing and vulcanizing other synthetic rubbers such as EPDM rubber alone, or natural rubber and styrene-butadiene rubber with suitable auxiliary agents. For example, the Chinese invention patent whose publication number is CN101891905A discloses a boneless wiper rubber strip, including natural rubber, vulcanizing agent, vulcanization accelerator, vulcanization activator, anti-scorch agent, anti-aging agent, reinforcing agent, filler, softener Auxiliary components, wherein the mass ratio of natural rubber to auxiliary components is 100:500-1200, and the auxiliary components also include one or both of styrene-butadien...
