Embodiment Construction

[0046] This example is a preparation method of a rubber-plastic synthetic ultra-thin condom. It uses synthetic polyisoprene as a matrix, and synthesizes a composite polymer material to prepare a condom by adding water-based polyurethane and a small amount of natural latex. The specific formula as follows:

[0047] Synthetic polyisoprene measured as dry glue 50 parts

[0048] Water-based polyurethane measured as dry glue 45 parts

[0049] Natural latex measured as dry rubber 5.0 parts

[0050] KOH concentration 20% solution 0.2 parts

[0051] Ammonia 25% solution 0.1 parts

[0052] Initiator 3.0 parts 。

[0053] The specific preparation method is as follows:

[0054] (1) Preparation process of rubber-plastic synthetic emulsion

[0055] ① Add 0.3 to 0.4 parts of stabilizer to 50 parts of synthetic polyisoprene material, the stabilizer is 25% ammonia solution and 20% KOH solution, and stir in the bucket for 20 minutes;

[0056] ②Add 45 parts of water-based polyurethane em...

Abstract

The invention discloses a preparation method of a rubber and plastic synthetic ultrathin condom. The preparation method comprises the following steps: by taking synthesized polyisoprene as a matrix, adding the synthesized polyisoprene, water-based polyurethane, natural rubber latex, KOH, ammonia water and an initiator under a certain condition, thereby synthesizing the condom prepared from a composite high polymer material. According to the preparation method of the rubber and plastic synthetic ultrathin condom disclosed by the invention, the preparation method adopting the synthesized polyisoprene, a little natural rubber latex and water-based polyurethane is used to substitute the original natural rubber latex process to prepare a condom product. The condom is not added with vulcanizing agents sulfur, zinc oxide, an accelerator, and the like, is slightly influenced by environment, and is increased in product qualified rate; the raw materials are good in performance and can be used for preparing the ultrathin condom which has the advantages of good skin affinity, no water-soluble proteins, no anaphylactic reaction on the human body, and the like.

Description

technical field [0001] The invention relates to the technical field of production of family planning appliances, in particular to a method for preparing a condom by compounding polyisoprene, natural rubber and polyurethane. Background technique [0002] The existing condom is a condom manufactured by synthetic natural rubber, natural latex and water-based polyurethane through pollution-free synthetic processing without additives. The product has thin thickness (0.02mm), good compactness, high barrier property, and Contains water-soluble protein and nitrosamines. The ultra-thin synthetic condom independently developed and produced by our company has the characteristics of ultra-thin, which increases the comfort of use, is biocompatible and safe, and has high physical strength, but there are also some defects, mainly in: the softness and expandability of the product The natural rubber is poor, and the product cost and use cost are high. Contents of the invention [0003] T...
