Description
Technical field
The invention belongs to rubber chemicals technical fields, and in particular to a kind of environment-friendly long-acting rubber softening agent method and its system
Preparation Method.
Background technology
Rubber must use softening agent, the rubber softening used in tyre industry at home and abroad in the past in process
Agent is mainly aromatic naphtha（DAE）.Due to aromatic naphtha（DAE）Contain a large amount of condensed-nuclei aromatics（Also it is polycyclic aromatic hydrocarbon）, and aromatic naphtha
Use in tire technical process can make to contain condensed-nuclei aromatics in tire, become product not environmentally.Condensed-nuclei aromatics is demonstrate,proved
It is real that there is larger toxicity.Eco-toxicity and the environmental science committee（CSTEE）It has had proven to be permitted contained in condensed-nuclei aromatics
More substances have significant carcinogenicity, mutagenicity and reproductive system toxic.Rubber product containing aromatic naphtha is being used
During, condensed-nuclei aromatics be just inevitably diffused into environment and and human contact, to jeopardize human health and poison
Evil environment.
The current most tire plants in China have started the substitute using aromatic naphtha, and current substitute is importer entirely
Outer product, mainly a kind of copolymerized petroleum resin, this kind of resin China cannot still produce at present.
Invention content
In view of the above technical problems, a kind of environment-friendly long-acting rubber softener of present invention offer and preparation method thereof.
Specific technical solution is：
Environment-friendly long-acting rubber softener includes each raw material of following parts by weight：20 ~ 40 parts of C5 Petropols, C9 Petropols 7
~ 16 parts, 10 ~ 18 parts of glycerine, 10 ~ 20 parts of naphthenic oil, 12 ~ 16 parts of ethylene propylene diene rubber, 5 ~ 12 parts of methyl anthranilate, second
8 ~ 15 parts of acetoacetic ester, 3 ~ 10 parts of limonene.
Further, 35 parts of the C5 Petropols, 12 parts of C9 Petropols, 15 parts of glycerine, 18 parts of naphthenic oil, ternary second
Third 15 parts of rubber, 9 parts of methyl anthranilate, 10 parts of ethyl acetate, 7 parts of limonene.
The method of the environment-friendly long-acting rubber softener, includes the following steps：（1）According to proportioning respectively by C5 oil trees
Fat, C9 Petropols, ethylene propylene diene rubber are placed in container, are warming up to 30 ~ 40 DEG C；
（2）After being mixed evenly, methyl anthranilate, naphthenic oil and glycerine are added into mixture, is mixed equal
It is even；
（3）Then ethyl acetate and limonene is being added successively, is stirring 5 ~ 10min；
（4）By step（3）Obtained mixture is cooled to room temperature, is then allowed to stand 5 ~ 10min to get the environment-friendly long-acting rubber
Softening agent.
Further, the step（3）It needs system being warming up to 60 ~ 90 DEG C before middle addition ethyl acetate.
Environment-friendly long-acting rubber softener provided by the invention will join with the excellent Third monomer of rubber material compatibility performance
With light dydrocarbon, the copolyreaction of carbon nine, generate and the excellent rubber softener of rubber material compatibility performance.This rubber softener is not
Only have the advantages that general aromatic naphtha is good with rubber material compatibility performance, and is free of condensed-nuclei aromatics.Use the rubber of the present invention
Softening agent manufacture radial is remarkably improved the comprehensive performance of radial, especially ring when other conditions are identical
Guaranteed cost.
Specific implementation mode
It is described in conjunction with the embodiments the specific technical solution of the present invention.
Environment-friendly long-acting rubber softener includes each raw material of following parts by weight：35 parts of C5 Petropols, C9 Petropols
12 parts, 15 parts of glycerine, 18 parts of naphthenic oil, 15 parts of ethylene propylene diene rubber, 9 parts of methyl anthranilate, 10 parts of ethyl acetate, lemon
7 parts of lemon alkene.
The method of the environment-friendly long-acting rubber softener, includes the following steps：（1）According to proportioning respectively by C5 oil trees
Fat, C9 Petropols, ethylene propylene diene rubber are placed in container, are warming up to 30 ~ 40 DEG C；
（2）After being mixed evenly, methyl anthranilate, naphthenic oil and glycerine are added into mixture, is mixed equal
It is even；
（3）Then ethyl acetate and limonene is being added successively, is stirring 5 ~ 10min；It is needed system before middle addition ethyl acetate
It is warming up to 60 ~ 90 DEG C.
（4）By step（3）Obtained mixture is cooled to room temperature, is then allowed to stand 5 ~ 10min to get the environment-friendly long-acting
