Description
Technical field
The invention belongs to the rubber unvulcanizate formula technique field of spinning, particularly a kind of Millable polyurethane rubber for spinning cot and preparation method thereof with rubber roll.
Background technology
The spinning rubber-roller rubber unvulcanizate that spinning enterprise now generally uses, be that material of main part is equipped with multiple Synergist S-421 95 and makes how by paracril or carboxylated nbr, because the wear resistance of paracril or carboxy nitrile rubber, weathering resistance is relative with elasticity relatively poor, in the use for satisfying different spinning process requirements, also need to carry out physics on the rubber roll surface, chemical treatment, and make the corresponding spinning kind of rubber roll kind, yarn count, need in the spinning process to change the rubber roll of corresponding kind according to the kind of being spinned, the throwing that is difficult to numerous spinning fiber raw materials of adaptation and characteristic fiber is spun, and closely spin and spandex core-covered no traverse technology spinning etc., spinning suiting is subjected to serious challenge, its elasticity and work-ing life are obviously not enough, and yarn quality is stablized and often fluctuation inadequately.Promote heavy ingot amount with present spinning industry, heavily the novel process of pressurization, long draft is incompatible, and work-ing life is short, production efficiency is low, production cost and handling cost increase.
Number of patent application 01131719.1 " drawing frame, comber surface non-treatment cot " is to be the rubber roll that material of main part is made with the paracril.Number of patent application 02112811.1 " production formula of spinning rubber-roller is not handled on the anti-crawl agentdefiection surface " is to be the rubber roll that material of main part is made with the carboxylated nbr.They all are to be the rubber roll that material of main part is made with paracril or carboxylated nbr, still have above-mentioned use defective.
It is the method that body material is made rubber roll with the urethanes that number of patent application 200710067831.0 " polyurethane rubber spinning rubber-roller " provides a kind of.It is that main vulcanizing agent is made spinning rubber-roller that this method adopts isocyanic ester, on Synergist S-421 95 kind and proportioning, have obviously different with the present invention, also different with the cross-link bond that the rubber reaction generates, the physical and mechanical properties of vulcanized rubber is also different, also there are differences in result of use with on work-ing life.
Summary of the invention
The objective of the invention is to overcome the shortcoming and defect that prior art exists, a kind of Millable polyurethane rubber for spinning cot is provided.
Another object of the present invention is to provide a kind of preparation method of above-mentioned urethane rubber unvulcanizate.
Purpose of the present invention is achieved through the following technical solutions: a kind of Millable polyurethane rubber for spinning cot, it is characterized in that, described urethane rubber unvulcanizate is made up of millable polyurethane elastomer, strengthening agent, softening agent, static inhibitor, protective agent, pigment, linking agent, crosslinking coagent and processing aid, and the components in mass portion number of described urethane rubber unvulcanizate is counted:
