Description
Technical field
The present invention relates to a kind of preparation method of rubber roll, particularly a kind of is the method that main raw material is made rubber roll with the polyurethane rubber, polyurethane rubber spinning rubber-roller.
Background technology
At present textile mills promote heavy ingot amount, the heavy weaving processing technology of pressurization, high draft, but the spinning rubber-roller that textile mills now generally use is many to be equipped with multiple compounding ingredient by acrylonitrile-butadiene rubber as the material of main body and to make, because the characteristic of acrylonitrile-butadiene rubber itself, when it is subjected to certain pressure, mechanical damage appears in the destroyed meeting of molecular structure, just can't satisfy the requirement of textile technology.This rubber roll different spinning process requirements in use in addition for satisfying that Quality Pure Cotton Yarn Production, blended yarn, hemp spinning yarn, wool spinning, silk spinning yarn, silk spinning are knitted etc., also need to carry out physics, chemical treatment on the surface of rubber roll, and make the corresponding weaving kind of rubber roll kind, yarn count, therefore in process, also need to change corresponding rubber roll according to the replacing of spinning kind, time-consuming, the effort production efficiency low, labor strength is big, has increased the management and the production cost of enterprise again.
Number of patent application CN02112811.1 " factory formula of spinning rubber-roller is not handled on the anti-crawl agentdefiection surface ", number of patent application CN01131719.1 " drawing frame, combing machine surface non-treatment cot ", though a kind of manufacture craft of the used rubber roll that spins all is provided, but they all still are to be the rubber roll that body material is made into the acrylonitrile-butadiene rubber, therefore still there are some above-mentioned defectives, can't satisfy the requirement of existing textile technology.
Patent No. CN200510010660.9 " polyurethane rubber roller ", number of patent application CN92109803.0 " preparation method of polyurethane rice huller rubber roller ", providing a kind of is the preparation method that material is made rubber roll with polyurethane, but they suit in the working environment of high speed and spraying industry glycerol or the use of working on the hulling machine, also are not suitable for doing spinning rubber-roller and use.
Summary of the invention
Technical problem to be solved by this invention is: a kind of polyurethane rubber spinning rubber-roller is provided, do main raw material making with polyurethane rubber and have the method for high elasticity, high-wearing feature spinning rubber-roller, the spinning rubber-roller that this prescription, method are produced need not carry out surface treatment, suitable face is extremely wide, improved the utilization rate of spinning quality and spinning equipment greatly, and prolonged service life, and reduced the production cost and the working strength of workers of spinning, play environmental protection, the effect of joint consumption again.
The present invention addresses the above problem the technical scheme that is adopted, the polyurethane rubber spinning rubber-roller prescription: each material is weighed, and main raw material(s) blending-type polyurethane M-PUR weight is 100%.
Phenolic resins 8～40%
Reinforcing agent (white carbon black) 5～20%
Vulcanization accelerator (DM.M) 0～15%
Plasticizer (dioctyl ester or coumarone indene resin) 10～40%
Activating agent (the chromium complex Zncl of zinc
2-Dm) 0～10%
Colouring agent (titanium dioxide) 0～30%
Vulcanizing agent (dimer TDI and isocyanates) 5～40%
Peroxide (two 2 5) 0.1～0.9%
Defoamer (BYK) 0～3%
Waterproofing agent (hydrolysis stabilizer diisopropylbenzene (DIPB) DCP) 0～10%
The above-mentioned commercially available prod that is is weighed back standby.
Production stage:
Plasticate: the blending-type polyurethane that weighs up is placed on to heat on the common rubber mixing machine plasticates three times, each ten minutes, temperature was controlled at below 50 ℃, and added cadmium stearate;
And use modification: on opening rubber mixing machine, the phenolic resin particle raw material of putting into roller is heated to more than 80 ℃, it is softened become block, roller is cooled to below 60 ℃ then, make blending-type polyurethane with softening after phenolic resins blend 15～25 minutes, and twice of freshening;
Mixing: according to first coarse fodder, back fines, the feeding sequence of vulcanizing agent again, each formula material that will weigh is respectively put into mill, and blending-type polyurethane, the phenolic resins good with freshening mix at normal temperatures;
Extrude: the sizing material that will mix, send into corresponding extruder by the requirement of product size specification, and the temperature that makes extruder is controlled in 40～65 ℃ of scopes, extrudes semi-finished product, aluminum pipe inserted the spinning rubber-roller that constitutes the aluminium insert structure in the semi-finished product of extruding at once;
Sulfuration; Utilize digester (-tor) that the said goods is vulcanized, temperature is controlled at 135～145 ℃, and cure time is 65～120 minutes;
After cure: it is in 115～125 ℃ the hot-air that said products is placed on temperature, carries out 1.5～2.5 hours additional sulfuration;
Processing and forming: press the job requirement of spinning rubber-roller, after surface of said articles is tempered, cut into the spinning rubber-roller of required size again.
Compared with prior art, the invention has the advantages that: so spinning rubber-roller is that material of main part is made with the polyurethane rubber, because of it has ultrahigh molecular weight and special building stone, and has a high elasticity, the spinning adaptability that high-wearing feature is become reconciled, so physical and mechanical properties by its spinning rubber-roller that is made into, the tear resistance index obviously is better than the acrylonitrile-butadiene rubber rubber roll, can satisfy the heavy ingot amount of existing spinning industry to greatest extent, heavily pressurization, the technological requirement of high draft, long service life is several times of acrylonitrile-butadiene rubber rubber roll life-span, because of it extremely wide applicable surface is arranged in addition, in spinning process, need not to change rubber roll because of the replacing of spinning kind, and need not any surface treatment, therefore the spare unit of spinning enterprise have been significantly reduced, the storage capacity of spare part and to the pollution of environment, reduced the management of spinning enterprise, processing cost, improved the utilization rate of spinning equipment, simultaneously a quality that is spinned is had by a relatively large margin raising, with the acrylonitrile-butadiene rubber rubber roll mutually specific energy improve with kind yarn count retaining time 1～2 grade.
The specific embodiment
Production stage:
Plasticate: the blending-type polyurethane that weighs up is placed on to heat on the common rubber mixing machine plasticates three times, each ten minutes, temperature was controlled at below 50 ℃, and the adding cadmium stearate prevents its roll banding as isolating agent;
