Description
Technical field
The present invention relates to aeronautical material manufacturing technology field, and in particular to a kind of rubber compound.
Background technology
Raw rubber is the main and key raw material of elastomeric material, and the performance of elastomeric material depends primarily upon raw rubber class used
Type.It can be divided to two kinds of high temperature polymerization and low temperature polymerization by polymerization technique, this depends primarily upon the initiator of selection reaction.High temperature gathers
The hard butyronitrile raw rubber closed generally forms distribution width, includes gel component height, and side chain is more, and Mooney viscosity is big, is needed when producing rubber compound
Repeatedly plasticated, poor in processability, machining energy consumption is huge, and foreign countries seldom apply in rubber.
Soft the butyronitrile raw rubber gel component and Mooney viscosity of low temperature polymerization are low, and microstructure regularity is high, average molecular matter
Measure narrowly distributing, it is not necessary to which plasticating can mixed refining process.
Domestic civilian nitrile rubber is from the 1980s substantially based on the soft butyronitrile of low temperature polymerization, but aviation is used
Nitrile rubber is since various aspects of performance problem, civilian nitrile rubber are unable to reach, and therefore, still mainly uses high temperature polymerization work
The hard butyronitrile raw rubber of skill production, hard butyronitrile raw rubber production technology seriously pollute environment, and hidden danger is continuous in terms of Environmental Safety.
Thus, it is desirable to have a kind of technical solution is come at least one above problem for overcoming or at least mitigating the prior art.
The content of the invention
It is an object of the invention to provide a kind of rubber compound come overcome or at least mitigate it is of the prior art it is at least one on
State problem.
To achieve the above object, the present invention provides a kind of rubber compound, the rubber compound to include：The auspicious father-in-law of 100 parts by weight
Butyronitrile DN4050；The vulcanizing agent of 3.5 parts by weight, the vulcanizing agent are peroxide and sulphur；The accelerating agent of 3.5 parts by weight；6 weight
The activating agent of part；The antioxidant of 3 parts by weight；The spraying carbon black of 70 parts by weight；The fine particle calcium carbonate of 25 parts by weight；The plasticising of 20 parts by weight
Agent, the plasticizer are dibutyl sebacate or di-n-octyl sebacate；The mould inhibitor of 5 parts by weight.
The rubber compound of the present invention is using soft butyronitrile raw rubber as raw material, and according to the purposes of aviation nitrile rubber, work bar
Part and index request, analyze the hard butyronitrile raw rubber used in original formulation with intending the soft butyronitrile raw rubber of use in molecular structure, composition
The raw rubbers such as distribution, molecular weight, molecular weight distribution, the degree of branching, gel content, the microstructure of butadiene short chain, segment distribution
Can and rubber compound aspect of performance difference, best substitute kind is theoretically found out on the basis of comparative analysis, then by with
Side's design, actual cooperation, be kneaded, vulcanization, and the nitrile rubber performance finally prepared reaches original index request.
