Description
Technical Field
The invention belongs to the field of rubber manufacturing, and particularly relates to a production formula and a process of a high-wear-resistance spinning drafting rubber roll applied to conditions of ultra-large drafting, high temperature and high speed operation.
Background
The rubber roller has wide application field, the textile drafting rubber roller is an important component of textile machinery, and the textile drafting rubber roller is used in a drafting area in the textile industry and is one of important components in the textile process. In the spinning process, fiber strands are drafted and twisted step by step for multiple times through a spinning drafting and stretching rubber roller to form yarns, the fiber strands are drafted and run between the rubber roller and the roller, the quality and the service performance of the rubber roller directly influence the yarn forming quality, and therefore the surface of the rubber roller is required to have good elasticity, wear resistance and proper hardness. The spinning rubber roller has the advantages that the abrasion consumption of the rubber roller is increased at high temperature due to the influence of various factors such as high-temperature high-speed running, super-large drafting multiple, heavy pressurization, electrostatic action and the like in the spinning process, the deformation frequency of the rubber roller is increased in unit time at high temperature, the hardness of the rubber roller is reduced, and the surface of the rubber roller is concave, so that the spinning quality is reduced. Therefore, the rubber which can adapt to the conditions of super-large draft, high temperature and high speed operation and can keep the wear resistance and a rubber modification method are absolutely necessary to be found.
Patent number CN201610284867.3 discloses a rubber formula of spinning rubber roll, the essential elements include carboxyl nitrile rubber, titanium dioxide, anti-aging, antistatic plasticizer, sulphur, zinc oxide, promoter, white carbon black, stearic acid, through adopting plasticizer TP-90B, it both has the plasticization, have antistatic effect again, thereby when guaranteeing that the product is produced smoothly, semi-manufactured goods safety storage, make the bulk resistance of rubber can reach 10^8, better antistatic effect has, and then effectively guaranteed the spinning quality. However, the patent does not study the crucial wear resistance of the rubber roller, and the rubber roller with poor wear resistance can seriously affect the service life of the spinning rubber roller, so that the requirement of practical application cannot be met.
Patent No. CN201811609379.0 discloses a high-wear-resistance rubber roll, which mainly comprises carboxyl nitrile rubber, titanium dioxide, an anti-aging agent, aluminum oxide, sulfur, zinc oxide, an accelerator, white carbon black and stearic acid. The wear resistance of the rubber is improved by adding alumina into the formula. However, the patent is only limited to improving the wear resistance of the rubber roller, but cannot ensure the performances of elasticity, strength and the like of the product and still cannot ensure the service life of the rubber roller.
The concrete manufacturing process of the rubber roller is also an important factor influencing the quality of the rubber roller, and the rubber roller for textile drafting is produced at home and abroad by adopting the processes of extrusion, encapsulation, steam vulcanization, cutting and grinding at present. The process has the advantages of multiple process flows, large labor consumption, easy core deviation of the rubber roller, large abrasion loss, waste of selected materials in the process and environmental pollution caused by waste water, and the process flow is shown in figure 1.
Disclosure of Invention
Aiming at the problems in the prior art, the invention aims to provide a rubber formula for manufacturing a textile drafting rubber roller and a production process thereof, which can improve the wear resistance of the textile drafting rubber roller, prevent the generation of a concave part in the using process, have long service life, and have oil resistance, swelling resistance and excellent winding resistance; meanwhile, the thickness of the rubber roller can be accurately controlled, core deviation of the rubber roller is prevented through accurate positioning of the die, waste of rubber materials is reduced, no waste water exists, and the environment is not polluted.
In order to solve the technical problems, the invention provides the following technical scheme:
a rubber formula for manufacturing a textile drafting rubber roll comprises the following components in parts by weight:
the invention enhances the wear-resisting and antistatic properties of the rubber roller by selecting the ether plasticizer, and the main chain of the ether plasticizer contains ether bond
The oligomer with terminal residue side group containing more than 2 carboxyl-OH is prepared by ring opening polymerization of low molecular weight polyol as initiator and olefin oxide under the action of catalyst. The alkylene oxides are mainly propylene oxide (propylene oxide), ethylene oxide (ethylene oxide), propylene oxide being the most important. Examples of the polyol initiator include dihydric alcohols such as propylene glycol and ethylene glycol, trihydric alcohols such as glycerin and trimethylolpropane, and polyhydric alcohols such as pentaerythritol, tetrahydric alcohol, sorbitol and sucrose.
The molecular structure of the ether plasticizer is as follows:
(1) the molecular structure has more-OH, so the yarn has a wetting effect and better spinning performance in the spinning process.
(2) In the molecular structure of
Has the antistatic effect and provides a lasting antistatic effect for spinning chemical fiber products.
(3)
and-OH is beneficial to material dispersion in the processing process, improves the crosslinking degree of the product and ensures that the vulcanized product is more wear-resistant.
Further, the ether plasticizer is polyhydric alcohol polyoxypropylene ether or polyhydric alcohol polyoxyethylene ether.
As the CSM is prepared by chlorosulfonation of polyethylene, the CSM has better wear resistance than nitrile rubber, and the product produced by the CSM has more excellent performance. Proper CSM is added into the formula, so that the wear resistance, strength and hardness of the product can be improved.
The carbon nano tube in the formula is used as a one-dimensional nano material, has light weight, perfect connection of a hexagonal structure and a plurality of abnormal mechanical, electrical and chemical properties. The p electrons of the carbon atoms on the carbon nano tube form a large-range delocalized pi bond, and the carbon nano tube has good electric conductivity and heat transfer performance due to the obvious conjugation effect.
Further, carbon atoms in the carbon nanotubes adopt sp2Hybridization, phase comparison sp3Hybridization, sp2The s-orbit component in hybridization is large, so that the carbon nano tube has the characteristics of high modulus and high strength.
The invention also provides a manufacturing process of the textile drafting rubber roller, which is used for producing by adopting a cold flow injection vulcanization process after mixing, and then packaging and warehousing after inspection.
The key point of the process is that the cold runner injection molding process is adopted for production, an unmanned factory can be realized in a vulcanization process, cutting, chamfering and grinding processes are not needed, and the process flow is shown in figure 2. The thickness of rubber roll can accurate control, through the accurate location of mould, can prevent the core of deviating from of rubber roll, reduces the waste of sizing material. The electric heating vulcanization is adopted, so that no waste water exists, and the environment is not polluted.
