Abstract
The invention discloses a wear and aging-resistant rubber which comprises the following components: carboxylated-terminated liquid acrylonitrile-polybutadiene rubber, styrene-butadiene rubber, octyl phenolic resin, zinc oxide, stearic acid, 4, 4'-bis (a , a'-dimethylbenzyl) diphenylamine, 2, 2, 4-trimethyl-1,2-dihydro-quinoline, glass fiber, carbon black N660, clay, calcium carbonate, tallow, pine tar, engine oil, dibenzothiazyl disulfide, 2-mercaptobenzothiazole, tetramethylthiuram disulfide, N-cyclohexyl-thio-dicarboximide and sulfur. According to the invention, the produced mixing rubber is observed under 2-time magnifying glass after being aged for 72 hours at 40 DEG C and no crack is observed, so that the wear and aging resistance is good.
Description
Technical field
The present invention relates to a kind of rubber, is a kind of wear-resisting anti-aging rubber for dredge rubber pipe outer covering layer specifically.
Background technology
In the last few years, the use range of dredge rubber pipe had had very large expansion, not only due to navigation channel desilting and the port construction of rivers,lakes and seas, and for engineerings such as man ground, islands and reefs exploitation, marine building, submarine mining.In the material of transporting, containing large particulate matters such as gravel, rock, corals, traditional dredge rubber pipe outer covering layer rubber is not wear-resisting, and easily aging, can very fast crack failure, have impact on sebific duct work-ing life.
Summary of the invention
In order to overcome problems of the prior art, the object of this invention is to provide a kind of wear-resisting anti-aging rubber, aging through 40 DEG C × 72h, amplify Microscopic observation at 2 times and have no crackle, wear-resisting anti ageing property is better, can meet dredge rubber pipe construction needs.
Object of the present invention is achieved through the following technical solutions:
A kind of wear-resisting anti-aging rubber, is characterized in that: this wear-resisting anti-aging rubber contains the material that following quality is divided:
