Embodiment 1

[0029] Example 1. The invention discloses a raw material dry-state proportioning of latex for ultra-thin condom production. Including dry sulfur, ZnO, zinc diethyldithiocarbamate, 2,6-di-tert-butyl-4-methylphenol, KOH, fatty alcohol polyoxyethylene (20) ether, six Sodium metaphosphate, sodium methylene dinaphthalene sulfonate and natural rubber latex. The dry mass ratio is sequentially 1.20 parts of sulfur, 0.70 parts of ZnO, 0.40 parts of zinc diethyldithiocarbamate, 1.00 parts of 2,6-di-tert-butyl-4-methylphenol, 0.08 parts of KOH, 0.25 parts of fatty alcohol polyoxyethylene (20) ether, 0.05 parts of sodium hexametaphosphate, 0.10 parts of sodium methylene dinaphthalene sulfonate, 100.00 parts of natural latex, and 3.00 parts of modified latex. The modified latex is natural latex grafted with MMA.

Embodiment 2

[0030] Example 2. The invention discloses a raw material dry-state proportioning of latex for ultra-thin condom production. Including dry sulfur, ZnO, zinc diethyldithiocarbamate, 2,6-di-tert-butyl-4-methylphenol, KOH, fatty alcohol polyoxyethylene (20) ether, six Sodium metaphosphate, sodium methylene dinaphthalene sulfonate and natural rubber latex. The dry mass ratio is sequentially 1.20 parts of sulfur, 0.70 parts of ZnO, 0.40 parts of zinc diethyldithiocarbamate, 1.00 parts of 2,6-di-tert-butyl-4-methylphenol, 0.08 parts of KOH, 0.25 parts of fatty alcohol polyoxyethylene (20) ether, 0.05 parts of sodium hexametaphosphate, 0.10 parts of sodium methylene dinaphthalene sulfonate, 100.00 parts of natural latex, and 3.50 parts of modified latex. The modified latex is natural latex grafted with MMA.

Embodiment 3

[0031] Example 3. The invention discloses a raw material dry-state proportioning of latex for ultra-thin condom production. Including dry sulfur, ZnO, zinc diethyldithiocarbamate, 2,6-di-tert-butyl-4-methylphenol, KOH, fatty alcohol polyoxyethylene (20) ether, six Sodium metaphosphate, sodium methylene dinaphthalene sulfonate and natural rubber latex. The dry mass ratio is sequentially 1.20 parts of sulfur, 0.70 parts of ZnO, 0.40 parts of zinc diethyldithiocarbamate, 1.00 parts of 2,6-di-tert-butyl-4-methylphenol, 0.08 parts of KOH, 0.25 parts of fatty alcohol polyoxyethylene (20) ether, 0.05 parts of sodium hexametaphosphate, 0.10 parts of sodium methylene dinaphthalene sulfonate, 100.00 parts of natural latex, and 4.00 parts of modified latex. The modified latex is natural latex grafted with MMA.

Abstract

The invention relates to a dried material ratio of rubber latex for producing ultra-thin condoms and a sulfuration technology for preparing the rubber latex. The dried weight ratios are respectively as follows: 1.20 portions of sulfur, 0.70 portion of ZnO, 0.40 portion of zinc diethyl dithiocarbamate, 1.00 portion of 2, 6-bis-tert buty-4-methyl phenol, 0.08 portion of KOH, 0.25 portion of fatty alcohol polyoxyethylene (20) ether, 0.05 portion of sodium hexametaphosphate, 0.10 portion of sodium methylene dinaphthyl sulphonate, 100.00 portions of natural rubber and 3.00 portions to 5.00 portions of modified rubber latex. The sulfuration technology comprises 10 steps and can be used for the preparation of the rubber latex for producing the ultra-thin condoms. The rubber latex can be used for the production of ultra-thin and ultra ultra-thin condom products with the thickness of about 0.050mm. Under the premise of guaranteeing the strength quality and meeting the national and international standards, the products have excellent comfortableness when in use, can realize effective contraception and also more effectively prevent the spread of diseases, such as AIDS, gonorrhea and chancroid and the like.

Description

technical field [0001] The invention belongs to the technical field of condom production, and more specifically relates to the improvement and innovation of the raw material dry state ratio of latex used for ultra-thin condom production and its preparation and vulcanization process. Background technique [0002] Natural latex rubber condom is a rubber film product made of vulcanized natural latex film-forming properties, mainly used to prevent the spread of diseases and contraception. With the continuous improvement of domestic and foreign consumers' requirements for the comfort of condoms, on the premise of ensuring product strength, the thinner the product thickness, the better. This requires manufacturers to continuously improve production processes to produce ultra-thin and ultra-thin condoms that can meet strength requirements, meet national and relevant international standards, effectively prevent the spread of AIDS and other viruses, and ensure comfort.
