Abstract
An antiflex rubber roller without surface treatment for spinning yarn is prepared from hydroxynitrile rubber, antistatic plasticizer, activating agent cross-linking agent, filler and multi-element protecting agent. Its advantages are no need of surface treatment, high antiwear performance and long service life.
Description
Technical field:
The invention belongs to spinning and exempt from processing technology field, relate in particular to the prescription of manufacturing that spinning rubber-roller is not handled on a kind of anti-crawl agentdefiection surface with the rubber roll surface.
Background technology:
Spinning rubber-roller is the very important equipment of the various spinning machines of industry such as cotton spinning in the textile industry, wool spinning, bast fibre spinning, spinning machine passes through spinning rubber-roller, repeatedly fiber (natural fiber, chemical fibre) is gripped and drawing-off, could twist resultant yarn equably, spinning rubber-roller has significant impact to the quality and the output of yarn.Spinning rubber-roller is in the spinning course of work, owing to produce electrostatic interaction, reasons such as adhesive attraction and mechanical force can produce fiber absorption, and then are wrapped in the rubber roll surface, cause Yarn break, to making rubber roll can not spin and influence spinning quality, output.Existing spinning rubber-roller is made up of common nitrile rubber, plasticizer, activating agent, crosslinking agent, filler and protective agent, and the colloid crosslink density is lower, and antistatic property is poor, during use wrapping phenomena can take place.Twining flower and causing broken end in order to prevent to spin must carry out surface treatment or ultraviolet ray irradiation with chemical coating to rubber roll, and service life is shorter.
Summary of the invention:
The objective of the invention is mainly to solve twine colored, the broken end problem of spinning rubber-roller to fiber.A kind of have good resistance static behaviour, smooth property, degreasing and anti-adstringency (humidity absorption and release) are provided, and the factory formula of spinning rubber-roller is not handled on long anti-crawl agentdefiection surface of life-span during use.
Composition of the present invention is: 1, hydroxyl nitrile rubber, 2, antistatic elasticizer, 3, activating agent, 4, crosslinking agent, 5, filler, 6, polynary protective agent.
By the variation of above-mentioned main component, can produce the anti-crawl agentdefiection surface of different hardness series and not handle spinning rubber-roller.
The present invention adopts the hydroxyl nitrile rubber, compare with common nitrile rubber, owing to introduced hydroxyl group in the molecule, chemism is strong, and in the drafting process to yarn fiber, the static content that rubber and yarn fiber friction produce is low, and be difficult for gathering, cooperate antistatic elasticizer simultaneously, can improve absorb-discharge humid, reduce surface tension.Hygroscopicity can reduce generation of static electricity, favourable electric charge dissipation; Lower surface tension and good wet putting can prevent that the rubber roll surface from forming water smoke, lower the puckery sticking effect to yarn fiber, have prevented that simultaneously the carbohydrate of yarn fiber from dissolving the adhesive attraction that produces, and reach antistatic, anti-stick puckery, anti-sticking and the yarn fiber of not reeling.Strong because of hydroxyl nitrile rubber molecular polarity again, sulfuration back crosslink density improves not, the structure exquisiteness, through repeatedly grinding use, still can keep the rubber roll surface to have smooth preferably property and degreasing, can prevent the rich fiber phenomenon of volume that mechanical force causes, prevent the sticking volume fiber phenomenon that nonpolar quasi-grease is made a concerted effort to cause by valence bond, improve yarn quality.
Because the hydroxyl nitrile rubber cooperates and with the polynary protective agent that cooperative effect is arranged, obviously improved intensity and wearability, improved ozone aging, oxygen aging, subdued aging protective action, the service life of energy significant prolongation spinning rubber-roller.Anti-wear performance is good, and rubber roll returns the mill phase and can extend to more than 10 months from 4 months, and can extend to 4 years service life from 1 year half.
The specific embodiment:
Embodiment 1:
100 parts of hydroxyl nitrile rubbers, 15 parts of antistatic elasticizers, 3 parts of activating agents, 3 parts of crosslinking agents, 10 parts of fillers, 3 parts of polynary protective agents.The finished product hardness (A) of present embodiment is 65 ± 3.
Embodiment 2:
100 parts of hydroxyl nitrile rubbers, 10 parts of antistatic elasticizers, 3 parts of activating agents, 5 parts of crosslinking agents, filler 15 minutes, 3 parts of polynary protective agents.The finished product hardness (A) of present embodiment is 70 ± 3.
Use spinning rubber-roller that above-mentioned prescription of the present invention makes behind correct grinding, need not any surface treatment, exempt from use chemical coating, the machine of can directly going up spins, lap-ups not, and wearability is good, long service life.
Claims (3)
