Abstract

The invention discloses a preparation method of a hydrotalcite-carbon black hybrid material as well as a hydrotalcite-carbon black hybrid material / rubber composite material and application thereof. Firstly amino silane is used for performing surface modification on carbon black, so that the surface of the carbon black is aminated, meanwhile, an acid anhydride-forming modifier is adopted to perform surface functionalization on hydrotalcite, and then the aminated carbon black and the hydrotalcite subjected to acid anhydride forming are uniformly mixed and are subjected to cosedimentation, so as to obtain a zinc-aluminium hydrotalcite-carbon black hybrid material. Further, a conventional method is adopted to add the hydrotalcite-carbon black hybrid material into rubber, so as to obtain the rubber composite material. The hydrotalcite-carbon black hybrid material used for natural rubber can endow the composite material with excellent properties such as mechanical property, ageing property and air barrier property, and more importantly can improve sulfuration resisting reversion property of the composite material.

Description

Technical field [0001] The invention involves the field of rubber materials, which specifically involves water-skid-charcoal black hybrid materials, and water talc-charcoal black hybrid materials added to the composite material obtained by natural rubber. Background technique [0002] Natural rubber (NR), as a good general rubber with good comprehensive performance, is widely used.However, in the sulfur vulcanization system, natural rubber composite materials will have varying degrees of vulcanization back to the original phenomenon, causing the performance of natural rubber composite materials to decrease, which greatly limits the application of natural rubber in industrial engineering products.In order to solve the problem of vulcanization, people have always troubled people and ensure the uniformity of products of products, people have been seeking solutions. [0003] The main method of improving NR's anti -sulfurization return performance from the reward mechanism of vulcaniz...
