Abstract

The invention belongs to the technical field of production of condoms, and in particular relates to a condom using modified biological starch as a separant and a preparation method of the condom. The condom is prepared by preparing separant suspension, which is used for replacing the conventional precipitated white carbon black separant suspension, by using the modified biological starch and a specific auxiliary agent by the conventional condom preparation process. Compared with the conventional condom using white carbon black as the separant, the condom has the advantages that: the surfaces of internal and external glue films are adhered with a separant with higher content which averagely reaches 50mg/piece approximately, so that a gap between the condom and an electrically-detected curled rear glue film is enlarged, the adsorption pull-up speed of a lubricant is increased, and the effect of penetration of the lubricant on the surface of a condom glue film is achieved; simultaneously, more sensitive touch feeling of the condom is endowed by the modified biological starch, and the lubricating effect of a customer during use is greatly improved, so that the condom can be easily accepted by broad customers during popularization and use.

Description

technical field [0001] The invention belongs to the technical field of condom production, and in particular relates to a condom with modified biological starch as a spacer and a preparation method thereof. Background technique [0002] In the general condom production process, it is necessary to wash the condom in the wet film state with a release agent in the process of dipping or post-sulfurization, so that a certain release agent is attached to the surface of the film, then dehydrated and dried, and then electro- Inspection, heat-sealed packaging, boxed cigarette seal, and finally the traditional condom made. Precipitated silica is attached to the surface of the prepared condom film. The powder material used in this traditional powder adding method is ------precipitated silica, and the amount of powder on the surface is relatively small, with an average of 25mg / Only below that, such a level of powder content makes the condom not loose enough, and the penetration of the ...
