Problems solved by technology

In 2018, the National Development and Reform Commission listed trans-butadiene rubber as high-quality synthetic rubber in the "Strategic Emerging Key Products and Services Guidance Catalogue". A large number of materials reported that tires and shock absorbing products containing trans-butadiene rubber have excellent comprehensive performance, but there are few studies on the synthesis and modification of trans-butadiene rubber

Abstract

The invention provides a trans-butadiene-isoprene rubber / filling oil composite material. The trans-butadiene-isoprene rubber / filling oil composite material comprises trans-butadiene-isoprene rubber, filling oil and an anti-aging agent, wherein the filling oil is one or more selected from aromatic hydrocarbon oil, naphthenic oil and paraffin oil. According to the invention, the filling oil and the trans-butadiene-isoprene rubber are mixed and modified, the trans-butadiene-isoprene rubber / filling oil composite material with higher processability than that of common trans-butadiene-isoprene rubber can be obtained by adjusting the dosages of the filling oil and the trans-butadiene-isoprene rubber, and is packaged by granulation or blocking; and compared with filling oil, the trans-butadiene-styrene rubber / filling oil composite material has excellent stiffness at normal temperature, can be packaged by adopting a plastic film, can customize the weight of a single package according to customer requirements, and is easy to store, transport and use. The invention also provides a preparation method of the trans-butadiene-isoprene rubber / filling oil composite material.

Description

technical field [0001] The invention belongs to the technical field of rubber, in particular to a trans-butadiene rubber / extending oil composite material and a preparation method thereof. Background technique [0002] There are two issues that have attracted much attention in the rubber industry. One is that labeling regulations impose higher requirements on the rolling resistance and wet skid resistance of tires. The other is that the environmental pollution caused by waste rubber products is becoming more and more serious. Traditional rubber materials are difficult to meet high-performance tires. And the demand for high performance of rubber products, the development and application of new rubber materials have become the focus of the industry. In order to meet the needs of the rubber industry and facilitate the development of green tires and long-life rubber products, trans-butadiene rubber came into being. [0003] Patent CN103387641A reports the preparation of trans-bu...
