Method for producing condom by mixing silk fibroin and graphene

Abstract

The invention discloses a method for producing condom by mixing silk fibroin and grapheme. The method is characterized by comprising the following steps: mixing silk fibroin and graphene with a proper amount of mixed components at the temperature of 20-30 DEG C to obtain a mixed latex, controlling a total solid content at 60% and a pH value of 3.8-7.0 during a mixing process, and standing for aging, immersing a condom mould with a proper shape in the mixed latex aged in the above step, and taking out the immersed condom mould and drying the condom mould at the temperature of 85-90 DEG C, forming an adhesive film on the immersed condom mould; performing treatment of regular edge rolling, drying, swelling, mould removing, soaking and powdering, and dehydrating on the adhesive film formed on the immersed condom mould, and drying and vulcanizing the adhesive film at the temperature of 100-120 DEG C to form the condom. The method has the beneficial effect that the prepared silk fibroin and graphene latex condom has the advantages of softness and toughness.

Description

technical field [0001] The invention relates to a method for preparing a condom, in particular to a method for preparing a condom by mixing silk fibroin and graphene. Background technique [0002] Most of the condoms currently on the market are made of natural latex. Condoms made from natural rubber latex can cause many health problems. Natural latex contains rubber plant protein and other substances that are allergic to the human body, so it is urgent to find high-quality natural latex substitute products in the world. For example, in recent years, the updated alternative materials polyisoprene and polyurethane have also been used as The substitute of natural latex has been used in the production of condoms, but the tensile thinness or toughness sensitivity of polyisoprene and polyurethane has not improved. When using cis-1,4-polyisoprene In the process of preparing condoms from rubber latex, people have found many problems, especially condoms, which have low tensile stre...

AI Technical Summary

Problems solved by technology

[0005] To sum up, all the research and invention of condoms at home and abroad are limited to natural latex or synthetic polyisoprene and polyurethane materials, and no pure natural raw materials have been invented in the fundamental alternative materials, which has failed to revolutionize sexual breakthrough

In terms of preparation technology or application, it only solves the problem of thinness or single softness and comfort
