| titleOfInvention | Process for prevulcanisation of natural latex and latex products |
| abstract | The invention provides a method for pre-vulcanizing natural latex and a latex product. The natural latex is precured by taking diallyl sulfide as a vulcanizing agent under the action of a free radical initiator. The latex product is prepared by using the prevulcanized natural rubber latex prepared by the natural rubber latex prevulcanization method. According to the natural latex prevulcanization method provided by the application, a cross-linking bond formed after prevulcanization is basically consistent with that of a traditional sulfur vulcanization system, the cross-linking bond is a polysulfide bond or a monosulfur bond, and the performance of a vulcanized rubber film is basically consistent; the pre-vulcanized natural latex prepared by the method has the advantages that the corresponding vulcanized rubber film is transparent, no nitrosamine residue and no zinc pollution are caused, and the problem of 'blooming' on the surface of a latex product can be thoroughly solved; the vulcanization degree of the prevulcanized natural latex is basically kept unchanged, and the prevulcanized natural latex can be parked for a long time, thereby being beneficial to the production management of downstream enterprises. |
