Description
Technical field:
The present invention relates to a kind of rubber squeezing roller flooring and squeezing roller making method, particularly a kind of rubber squeezing roller flooring and squeezing roller making method of adding nano material.
Background technology:
Cold rolled sheet factory degreasing unit is because of its distinctive high-speed production characteristics, also brought in ordinary production thus, online rubber rollers (especially squeezing roller) is because the roller footpath is smaller, rotating speed is high, quick-fried roller takes place in operational process easily, treatment time is grown (especially lower roll was more exchanged treaties 4 hours) again, had a strong impact on the unit ordinary production, production capacity can't be brought into play; Though can repair to rubber rollers, but because squeezing roller roller footpath is smaller, rotating speed is high, rubber rollers is in the circulation of extruding-resilience fast for a long time, stress can't effectively be discharged, quick-fried roller phenomenon does not take place when guaranteeing that rubber rollers is online, can only shorten the replacement cycle originally is 20 days, simultaneously the rubber rollers that rolls off the production line is not taked the way of reconditioning, carry out encapsulate again, caused the rising of production cost.
Cause the reason of quick-fried roller to have a lot, but main, most critical still the tensile strength of elastomeric material can't satisfy high speed rotating the time extruding repeatedly (tangential and positive pressure direction), the stretching of circumferential direction and the fatigue damage of elastic recovery that produce.Described elastomeric material generally adopts paracril, and the concrete parameter of nitrile rubber has tensile strength to require to more than the 15Mpa, and elongation is more than 250%, and being out of shape 3 minutes is below 25, and Akron abrasion is less than 0.3.But can not satisfy the requirement that the degreasing unit is produced, quick-fried roller takes place repeatedly.In order to reduce the unbalance stress of roll surface,, make it stressed evenly, and then avoid owing to the roll surface discontinuity causes quick-fried roller by every pair of squeezing roller is regulated roll surface with the aluminium-foil paper impression; In order to reduce the stressed of roller, adopted the way that reduces the roller cylinder pressure under the prerequisite of extracting requirement satisfying, from original 4 kilograms reduce to the 0.5-2 kilogram, and this method is also quite effective, but can not stop quick-fried roller, may influence simultaneously to extract effect.So stop quick-fried roller, must make rubber rollers have higher draw tensile strength, by changing the roll surface material, rubber rollers can normally be moved under the high-speed and high current density of 900m/min.
Summary of the invention:
The purpose of this invention is to provide a kind of rubber squeezing roller flooring and squeezing roller making method of adding nano material, mainly solve the technical problem of the quick-fried roller of rubber squeezing roller.Technical scheme of the present invention is: a kind of rubber squeezing roller flooring that adds nano material, and its weight part of forming component is:
Paracril: 100 parts
White carbon black: 50-60 part
Dibutylester: 10-16 part
Carbon black: 25-40 part
Glycol ether: 1-4 part
Zinc oxide: 6-15 part, wherein Nano-class zinc oxide 2-8 part
Stearic acid: 1-6 part
Potter's clay: 20-35 part, wherein nano level potter's clay 5-10 part
Nano level barium sulfate: 6-16 part
Nano level talcum powder: 5-15 part
The ancient Malong of solid: 2-6 part
Toughener: 2-6 part
Promoting agent: 2-6 part
Vulcanizing agent: 2-6 part
Anti-aging agent: 2-8 part
Promotor: 1-4 part
The squeezing roller making method, at first carry out rubber refining, slice after filtering, the squeezing roller roller core need carry out sandblast and starching before the bag sheet, carry out encapsulate, Zha Ganbu then, put cloth finishing and top former, to carry out Zha Shuibu after sheet rubber is coated on the roller core, tear former open, put cloth and car mill, obtain finished product at last.Wherein rubber refining is at first to be mixed the raw material except that paracril, adds paracril then and carries out mixingly, and various Synergist S-421 95s need be dispersed in the paracril uniformly in mixing process.Squeezing roller need vulcanize after pricking water cloth operation, and sulfide stress 0.14Mpa～0.35Mpa, curing time are 10 hours.
The invention has the beneficial effects as follows: the present invention is owing to added the nano level admixtion in the roll surface material, the use nano material can not only improve the reaction homogeneity in the rubber refining process, also can improve physicals and the thermostability and the chemical stability of matrix material, improve the rubber composite aging resistance thereby reach, the life-span purpose that prolongs goods.Nano material and usefulness, make that roll surface tensile strength, tensile yield are higher, Akron abrasion obviously reduces.Increase with the nano material consumption, the tensile strength wear resisting property of cross-linked rubber further improves, and this is because nano material can improve the cross-linking density of cross-linked rubber, increases the Young's modulus of rubber.By Shanghai glue grind detection, do not add nano material and add the nano material detected result seeing Table 1.The roll surface tensile strength is brought up to 27.3MPa, improves 60% than former technology, and elongation brings up to 410%, and Akron abrasion is reduced to 0.08.The time lengthening 50% that squeezing roller of the present invention uses on the degreasing unit, and can use on the machine once more after the reconditioning, reach 67% of new roller duration of service.
