A kind of release agent for condom production and preparation method thereof

Abstract

The invention belongs to the technical field of birth control apparatus, and in particular relates to a separant for condom production and a preparation method thereof. The separant is a suspension liquid composed of the following components by weight percent: 3% to 9% of light calcium carbonate, 1% to 3% of light magnesium carbonate, 0.2% to 0.5% of organic silicon assistant and the balance of water. For a condom prepared from the separant, the content of the separant adhered to the surface of a glue film of the condom is higher, up to 35mg in each condom on average; and the surface of the glue film is finer and smoother, so that the damage probability of the condom in use is lowered greatly. As a result, the condom can be easily accepted by broad masses of consumers.

Description

technical field [0001] The invention belongs to the technical field of family planning devices, and in particular relates to a release agent used in condom production and a preparation method thereof. Background technique [0002] In the production process of general condoms, it is necessary to wash the condom in the wet film state with a release agent during dipping molding and demoulding and post-vulcanization, so that a certain release agent is attached to the surface of the film, and then dehydrated and dried. After electrical inspection, heat-sealed packaging, boxed cigarette seal, and finally made of traditional condoms. The surface of the product obtained is precipitated white carbon black. The powder material used in this traditional powder adding method has a relatively small amount of powder attached to the surface of the condom film, with an average of less than 10mg / condom. This level of powder content makes The amount of simethicone attached to the condom is in...

AI Technical Summary

Problems solved by technology

The surface of the product obtained is precipitated white carbon black. The powder material used in this traditional powder adding method has a relatively small amount of powder attached to the surface of the condom film, with an average of less than 10mg / condom. This level of powder content makes The amount of simethicone attached to the condom is insufficient, and it is of little help to the penetration of simethicone. At the level of 600mg / condom of silicone oil, it still cannot penetrate completely after 70 days. In addition, precipitated silica has no effect on simethicone. The adsorption capacity is small (oil absorption value (ml / 100g) ≤ 18)
