Description
Technical field:
The present invention relates to a kind of printing rubber roll dedicated elas-tic composite material and preparation method thereof.
Background technology:
Developing rapidly along with high-speed printer in recent years, crucial elastomer member-the printing rubber roll that is used to transmit water and printing ink is had higher requirement,, high abrasion resistance little as good springiness, oil-proofness height, dynamic heat build up, easy cleaning, surface property good (have suitable absorption and transmit the ability of printing ink or water), dynamic fatigue life-span are long, and be suitable for the advanced winding process of extruding simultaneously, common rubber roll material in the past has been difficult to take into account above-mentioned requirements.
The hardness of printing rubber roll is in 20-99 degree scope, and wherein the soft rubber roll in the 20-45 degree durometer level prepares the difficulty maximum.The printing rubber roll rubber unvulcanizate of current numerous manufacturer production, though most of physical and mechanical properties has also reached certain level, for the printing rubber roll of hardness at the 20-45 degree, the very low (ML of the Mooney viscosity value of (1) its sizing material
1+4100 are about 5-8), cause when the winding complete processing is extruded in use, adhesive tape trickling and serious sagging appear, twine disconnected glue of the low and easy appearance of glue intensity and defective, heavy glue is also comparatively serious during sulfuration, therefore can't application of advanced extrude winding technology, can only prolong the manual encapsulate technology that falls behind with tradition; (2) intensity, wear resistance, solvent resistance are also lower.
How to make rubber in the lower hardness of maintenance, increase its Mooney viscosity value, be an insoluble problem of this area always.
Summary of the invention:
The purpose of this invention is to provide a kind of printing rubber roll dedicated elas-tic composite material and preparation method thereof, make the relation between rubber unvulcanizate processing mooney viscosity, flowability and cross-linked rubber hardness obtain the balance adjustment.
The present invention is a kind of printing rubber roll dedicated elas-tic composite material, and it is formed and parts by weight are:
Paracril 100
Carboxyl end of the liquid acrylonitrile-butadiene rubber 5-20
Zinc oxide 0.5-10
Hard ester acid 0.5-4
Sulfur 1-10
Tetramethyl-thiuram disulfide (promotor TT) 0.1-3
2-benzothiazolyl mercaptan (captax) 0.1-5
White carbon black 5-40
Silane coupling agent 0.1-10
Fibrillar silicate 1-50
Xylogen 1-30
Dioctyl phthalate (DOP) (DOP) 5-60
Polyester plasticizer 5-40
Magnesium oxide 0.1-3
Dicumyl peroxide 0.1-1
Above the particle diameter of said white carbon black be 10-40nm; Used silane coupling agent is two (triethoxysilylpropyl) tetrasulfides; Used polyester plasticizer is polytrimethylene adipate or poly-hexanodioic acid butylidene ester.
The preparation method of printing rubber roll dedicated elas-tic composite material of the present invention comprises the following steps: successively
Under 120-150 ℃, add paracril rubber, carboxyl end of the liquid acrylonitrile-butadiene rubber, zinc oxide, hard ester acid, silane coupling agent and white carbon black in the Banbury mixer, controlled temperature is at 120-150 ℃, under rotor speed 60-80 rev/min shearing rate, mixing 5-10 minute, finish the in-situ modified dispersion of white carbon black; Add xylogen, fibrillar silicate, polyester plasticizer and dioctyl phthalate (DOP) then, after mixing 5-12 minute, add dicumyl peroxide and magnesium oxide, under similarity condition, mixing 2-4 minute, finish dynamic little crosslinking reaction that various auxiliary agents are finished matrix and carboxyl end of the liquid acrylonitrile-butadiene rubber mixing the time, binder removal, in mill, add Sulfur, tetramethyl-thiuram disulfide, 2-benzothiazolyl mercaptan, mixing even.
The present invention adopts superoxide as dynamic little crosslinked linking agent.Because when the sizing material of low Mooney carried out high-temperature mixing in Banbury mixer, superoxide produced and decomposes, its free radical can make paracril produce to a certain degree little crosslinked.After this thermal treatment, rubber unvulcanizate has improved mooney viscosity in the certain amplitude scope in the good flowability of maintenance, and the hardness increase of final cross-linked rubber is extremely slight.
Xylogen is the low-cost amorphous powder of a class, it is the organism of various active groups such as a kind of hydroxyl, carboxyl, methoxyl group, easily and mineral filler and rubber generation chemical reaction, methylol further condensation when sulfuration forms appropriate lignin resin network between lignin molecule or lignin molecule.We utilize its these characteristics that it has been obtained good effect as strengthening agent.Our research also shows, because xylogen is a kind of soft filler, it is little to the material hardness influence, and can improve and regulate and control biography water, the ink transfer performance of sizing material effectively.
The present invention disperses and dynamic little crosslinked two technology by using original position-modification, successfully solved printing rubber roll and prepared between existing soft, moderate Mooney with elastic composite and be difficult to take into account, and soft, high strength, high abrasion and be difficult between the high life take into account etc. technical barrier.The characteristics of matrix material of the present invention are: add man-hour extruding to twine, and process stabilizing, respond well, sagging and disconnected bar phenomenon does not take place; During sulfuration, heavy glue phenomenon does not take place in rubber roll; After the sulfuration, the excellent performance of sizing material---soft, high strength, high abrasion have good oil resistant, oil resistant performance of ink, and wetting ability is better, and price is low.
