Description
Technical field
The present invention relates to field of fine chemical, more particularly to a kind of response type rubber grain dispersing agent and its preparation side
Method.
Background technique
Current rubber disperse agent is many kinds of, and main function is: improving point of carbon black and other powders in rubber
Dissipating property is mostly the polymerization product of polymeric fatty acid esters or the mixture with metal soap.Adapted dispersing agent can add in sizing material
Fast powder lot dispersing prevents roll banding, reduces incipient scorch and shorten process time.This polymeric fatty acid esters removes and helps powder lot dispersing function
It can be outer.Also there is plasticizer effect.Be conducive to improve rubber mobility.This kind of product is mainly the profit of application surface activating agent
The performances such as wet, dispersion, infiltration.Such as Chinese patent: CN201710842191.X, composition are plant base soya-bean oil oleic acid: 35~45
Part, lauryl sodium sulfate: 2~10 parts, higher alcohol: 6~16 parts, erucyl amide: 25~35 parts, microwax: 2~5 parts, this point
Powder prepares simple and safe, reduces influence of the dust to human body, the dispersing agent prepared is keeping good dispersion effect
Under the premise of, there is excellent processing service performance, cost performance is higher, and environmentally protective.Patent CN201710036338.6, it is a kind of
Environment-friendly rubber flows dispersing agent, by 60-70 parts of fatty acid, 6.5-7.6 parts of magnesium hydroxide or 4.5-5.3 parts of magnesia, and fatty acid
10-20 parts of ester, 0-10 parts of wax, 0-14.7 parts of resin.It is made by heating stirring, drying, granulation；Preparation method is simple, it is quick,
It is pollution-free；The main component of flowing dispersing agent includes fatty acid magnesium soap, aliphatic ester, wax and resin, environment-protecting and non-poisonous；Can effectively it change
Kind peptizaiton and products appearance of the filler in rubber matrix；The sulphur of sizing material is not influenced while improving sizing material processing performance
Change performance, the processing of rubber product and application security is enable to be largely increased.Suchlike product is there are also very much, with full
The demand produced enough.
Present rubber disperse agent is mainly to reduce the interfacial energy of each component of rubber especially black and white carbon black and come
Each component of rubber is allowed to disperse in process, merge, but there is also white, bloom disadvantage is returned, the reason is that not making each
A component increases bonding force, that is, without generating ionic bond, covalent bond.
In conclusion in view of the drawbacks of the prior art, it is accordingly required in particular to a kind of response type rubber grain dispersing agent and its preparation
Method, so as to solve the deficiencies in the prior art.
Summary of the invention
Aiming at the problems existing in the prior art, use in practice is influenced, the present invention proposes a kind of response type rubber
Grain dispersing agent and preparation method thereof, it is novel in design, make each component especially black and white carbon black of rubber, it is easier to be distributed to rubber
In, and be combined together, solve the defect of the prior art.
To achieve the goals above, technical scheme is as follows:
A kind of response type rubber grain dispersing agent, by following raw material proportion count by weight percentage are as follows:
Alkyl ketene dimer 50-60%；Aliphatic ester 15-30%；
Fatty acid salt 15-30%；Microwax 10-20%.
Further, the raw material of dispersing agent proportion count by weight percentage are as follows:

Further, the raw material of dispersing agent proportion count by weight percentage are as follows:
Alkyl ketene dimer 50%；Aliphatic ester 20%；
Fatty acid salt 20%；Microwax 10%.
Further, fatty acid ester is four ester of stearic acid pentaerythrite, three ester of stearic acid pentaerythrite, palmitinic acid hexadecanol
Ester, three hydroxy stearic acid ester of glycerol, tristerin, olein, sorbic alcohol acid anhydride stearate, geoceric acid stearyl alcohol ester,
One of oleic acid tristearin.
A kind of preparation method of response type rubber grain dispersing agent: material weight ratio is weighed in formula, after weighing respectively
The mechanical progress melting mixing of fusion is added, after being heated to 80~120 DEG C, is granulated after melting after cooling film-making or melting to get rubber
Glue particle dispersants.
The beneficial effects of the present invention are: it is novel in design, introduce the alkyl ketene dimerization that chemical bond is generated with rubber components
Body, cost is relatively low, produces extensively, is easy purchase, is suitable for being widely applied, and effect is prominent, has existing product great
It breaks through, for using client, not only increases performance, but also reduce cost, be favorably to select, be a kind of good innovation scheme.
