Method for preparing novel condom by blending high molecular materials

Abstract

The invention discloses a method for preparing a novel condom by blending high molecular materials. The various high molecular materials are properly blended, in the blending process, the total solid content is controlled to be 20%, the pH value is controlled to be 5.5-7.0, and blended latex is obtained, subjected to standing and ripened; and a condom mold in a proper shape is dipped in the blended latex and then taken out and dried after being dipped, so that a rubber film is formed on the condom mold, and the rubber film formed on the condom mold is subjected to conventional edge curling, drying, swelling, demolding, steeping and washing, powdering and dehydration treatment, and then is dried for 50 min at 100 DEG C. Compared with the prior art, the method has the beneficial effects that the technology for preparing the condom by blending the high molecular materials is adopted, all the materials are environmentally friendly and free of toxicity and pollution, and the condom is non-allergic, high in density, free of leakage, resistant to various viruses and good in sensitiveness and skin-friendly texture.

Description

technical field [0001] The invention relates to a method for preparing a condom, in particular to a method for preparing a novel condom by mixing polymer materials. Background technique [0002] At present, the condoms produced in domestic factories and sold on the market are all made of natural rubber latex. Condoms made from natural rubber latex can cause many health problems. Natural latex contains rubber plant protein and other substances, which have many problems such as allergic reaction, leakage, and weak virus defense to the human body. It has not changed for more than a hundred years, so it is urgent to develop or find high-quality natural latex substitute products all over the world, and various synthetic materials are limited to natural latex substitutes. For example: In recent years, the updated alternative materials polyisoprene and nitrile rubber have also been used as substitutes for natural latex, and have been used in the production of condoms, but the mix...

AI Technical Summary

Problems solved by technology

For example: In recent years, the updated alternative materials polyisoprene and nitrile rubber have also been used as substitutes for natural latex, and have been used in the production of condoms, but the mixing technology of polyisoprene and nitrile rubber Condoms have no improvement in tensile thinness or toughness sensitivity. They do not have the sensitivity and skin-friendly texture of synthetic condoms made of polymer materials. Condoms made of polymer materials have successfully used high-tech technology to solve basic needs such as ultra-thin and sensitive. , and better improve the leap-forward progress in many aspects such as non-allergic condoms, high-density non-leakage, and full isolation of various viruses, so the industry is epoch-making.
