Description

technical field [0001] The invention relates to the technical field of chloroprene rubber, in particular to a low-temperature and aging-resistant chloroprene rubber composite material. Background technique [0002] Neoprene is one of the important varieties of synthetic rubber. It has excellent mechanical properties, heat resistance and corrosion resistance. It has been widely used in the manufacture of industrial rubber products, such as wire and cable sheaths, oil-resistant hose rubber sheets, conveyor belts, Conveyor belts and various types of adhesive tape and shoe adhesives, etc. However, chloroprene rubber has poor cold resistance, and it will show a glassy state below -40°C, and it will age under the influence of oxygen, water, ozone, etc. during long-term use. These defects limit its use in some special applications. field applications. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes ...
