Description
Technical field
The invention belongs to rubber technical field of composite preparation, especially have EP rubbers base oligomer ester premixing glue
And its application field.
Background technology
Oligomer ester is a kind of Multifunctional rubber oils compounding agent, and during rubber processing, the oligomer ester of oils is not only
It can play the role of softening oil, be conducive to the machine-shaping of rubber, moreover it is possible in the sulfidation of later stage rubber, participate in vulcanization
Reaction, to realize the humidification to rubber product.But there are problems during the addition process in oligomer ester, for example,
The weighing and charging of thick oligomer ester are all relatively difficult, and wall can be glued in container, and metering is susceptible to error；Refining glue initial stage,
The addition of oligomer ester causes rubber to skid on rubber mixing equipment, is unfavorable for refining glue；Refining glue later stage, oligomer ester can cause sizing material serious
Roll banding causes mixing time to extend, and reduces production efficiency.Therefore, how oils oligomer ester to be preferably added in rubber, is kept away
Exempt from processing problems, while the maximum function of oligomer ester can be played, is one of the hot issue in current rubber industry.
Invention content
The purpose of the present invention is to provide a kind of EP rubbers base oligomer ester premixing glue and preparation methods.
A kind of EP rubbers base oligomer ester premixing glue, it is characterised in that including following components：100 mass parts of EP rubbers,

The accelerating agent is the 2 of TMTD and DZ:1 mixture.
The filler is the one or two of N220 and precipitated calcium carbonate, and anti-aging agent is antioxidant 264 or 4010NA
One or two.
A kind of preparation method of EP rubbers base oligomer ester premixing glue, it is characterised in that comprise the steps of：
Rubber is put into open mill, adjustment roll spacing is 10mm, and anti-aging agent and chromium stearate is added, and is kneaded 2-5min, and addition is filled out
Material is kneaded 2-4min, and adjustment roller temperature is added oligomer ester to 5 DEG C, is kneaded 5-7min, and accelerating agent and cumyl peroxide is added,
It is kneaded 5-8min, roll spacing is adjusted to 1mm by adjustment roller temperature to 80 DEG C, the thin logical 10-20min of sizing material, adjusts roller temperature to 5 DEG C, under
Piece is cut, and puts into extruder, is squeezed out pelletizing and is obtained EP rubbers base oligomer ester premixing glue.
Compared with prior art, the present invention its remarkable advantage is：
（1）Oligomer ester is blended in advance with EP rubbers, using the unsaturated double-bond in oligomer ester, is promoted by the way that quantitative blending is added
Into agent and cumyl peroxide, the partial dynamic vulcanization of premixing glue is realized on a mill, makes part oligomer ester and the third rubber of second
Glue crosslinks, and forms microgel and solves the problems, such as high oil plant premixing glue low viscosity roll banding to improve the viscosity of sizing material,
And it can ensure the normal flow processability energy of sizing material in subsequent high temperature processing, obtained oligomer ester premixing glue is convenient for making
Grain is preserved, transports and is weighed, and is effectively improved the utilization rate of oligomer ester, is avoided being stained with roller problem；
（2）When premixing glue is applied to using EP rubbers as in the rubber product of matrix, the microgel in premixing glue with it is unreacted
Oligomer ester continues to participate in the vulcanization reaction of rubber matrix, on the one hand, microgel reacts with rubber matrix, formation and rubber
There is the microgel reinforcing agent of chemical bonding in matrix body, further reinforcement is realized to rubber matrix, on the other hand, unreacted neat
Polyester participates in the vulcanization reaction of rubber matrix, and cross-linked network structure is formed in rubber matrix, vulcanizes shape with rubber matrix itself
At cross-linked network formed interpenetrating, further improve the performance of rubber product.
