Technical field
The present invention relates to a kind of methods for improving rubber roller cushion rubber performance, belong to technical field of rubber vulcanization.
Background technique
Cushion rubber, rubber roller are under pressure by roller frictional drive in spinning process, and form effectively with roller
Jaw forms friction field, can effectively hold yarn and fiber, so that going on smoothly for drawing-off is kept, and curable grip, frictional force
It is directly proportional to rubber roller cushion rubber elasticity, therefore the elasticity of spinning quality and rubber roller, tensile strength count for much, high resiliency, Gao Lashen
The rubber roller of intensity can significantly improve the grip of drawing rollers jaw, and have for improving resultant yarn strand, reducing yarn defect
Remarkable result.
Nitrile rubber is polymerized by butadiene and acrylonitrile monemer, polymerization when butadiene and acrylonitrile arrangement simultaneously
Irregularly, random structure has a significant impact to the performance of rubber roller, cushion rubber, while nitrile rubber elasticity, hardness, wearability phase
Mutual contradiction mutually restricts, and contradiction is more between comprehensive performance, thus improve its elasticity, have in tensile strength certain limit with
Difficult point.
In order to improve its performance, consider from coefficient of friction, the first cotton spinning knitting mill Mao Meiliang uses interior decorative pattern, reduces glue
The real contact area for enclosing surface and upper and lower pin stick, is made under the same pressure, inner-grained aprons internal layer elasticity becomes by this change
Shape is greater than smooth surface cushion rubber to improve cushion rubber elasticity, and considers from rubber material, Xu Zhongqiang using ultraviolet light to its surface into
Row irradiation, coefficient of friction have increase tendency compared with conventional acid treatment, and performance is promoted, but energy is lower, and performance improvement is not bright enough
Aobvious, Ge Qionghua is promoted to show using gamma-rays to cushion rubber rubber roller progress irradiation behaviour handles close effect, but production with acid
Safety is not high, there is certain limitation in actual production.Therefore, it needs to study at present and invents a kind of method and further increase rubber roller
The method of cushion rubber performance.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of raising rubber roller cushion rubber elasticity, tensile strength performance, extension are burnt
The method of time is burnt, and there is good security performance to be conducive to futurity industry production.
A method of rubber roller cushion rubber performance being improved, the step of the method are as follows:
The first step, by electron beam to molding nitrile rubber in 25~100 DEG C of progress vulcanizing treatments of irradiation temperature, irradiation
Number is 1~5 time；

Device generates.
Preferably, the irradiation dose 5-70kGy of vulcanizing treatment described in the first step, irradiation time is in 1s-6min.
Preferably, molding nitrile rubber described in the first step is by by filter glue, disappearing auxiliary agent, nitrile rubber mixing
Except the impurity in sizing material, through extruder extrusion molding, the mixing is completed by mixer.
Preferably, the auxiliary agent includes common sensitizer, activator, age resister, antistatic agent, antiscorching, vulcanization
Agent, promotor, reinforcing agent.
Preferably, the sensitizer includes trimethylol-propane trimethacrylate TMPTMA；Activator includes oxidation

Preferably, curing temperature described in second step is 140-160 DEG C.
Preferably, pressure described in second step is 0-1MPa.
It has the beneficial effect that:
The mode provided through the invention first passes through electron beam and carries out vulcanizing treatment, do not only reach pre-setting, can also excite
The free group of certain amount cooperates the steam-type sulfurizing pot vulcanization under subsequent certain condition to handle, then it can be made to be more likely formed
Reticular structure keeps the crosslinking of rubber roller cushion rubber more thorough.Products obtained therefrom is each in elastic property, tensile strength, time of scorch etc. simultaneously
It is promoted in the required performance of a rubber roller cushion rubber, while production security is improved, and its production efficiency is higher than original
Production efficiency.
