Abstract

The invention provides a high transparent high thermoplastic chloroprene rubber pipe and a preparation method thereof. The high transparent high thermoplastic chloroprene rubber pipe is prepared from 40 to 60 parts by weight of chloroprene rubber, 40 to 60 parts by weight of nitrile rubber, 45 to 55 parts by weight of white carbon black, 0.5 to 1.5 parts by weight of high abrasion resistance furnace black, 0.5 to 1 part by weight of an anti-aging agent, 0.6 to 1.2 parts by weight of a liquid softener, 3 to 7 parts by weight of a promoter, 3 to 5 parts by weight of zinc oxide, 1 to 2 parts by weight of magnesium oxide, 50 to 60 parts by weight of stearic acid and 0.5 to 1.5 parts by weight of sulfur. The chloroprene rubber and the nitrile rubber are combined and produce synergism so that the high transparent high thermoplastic chloroprene rubber pipe has excellent wear resistance, tensile strength and tear strength. The preparation method realizes a low production cost, has simple processes and is easy to control.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a high wear resistance transparent high thermoplastic neoprene tube and a preparation method thereof. Background technique [0002] Neoprene is one of the seven synthetic rubbers. Synthetic rubber is generally divided into general-purpose synthetic rubber and semi-general-purpose synthetic rubber, of which styrene-butadiene rubber, butadiene rubber and isoprene rubber are general-purpose, and neoprene, nitrile rubber, ethylene-propylene rubber and butyl rubber are semi-general-purpose. Semi-general synthetic rubber can be said to be a general-purpose special synthetic rubber with a large quantity and a wide range. It not only has the general properties of most general-purpose synthetic rubbers, but also has outstanding physical properties (such as oil resistance, solvent resistance, heat resistance , chemical stability, aging resistance and air tightness, etc.), so the ...
