Embodiment 1

[0024] The preparation method one of safety latex gloves comprises the following steps;

[0025] (1) Raw material preparation. Heat the raw latex to 65°C after adding the accelerator vulcanizing agent, heat preservation and pre-vulcanization, stop vulcanization when the chloroform value reaches the third to the third middle, and stop the vulcanization after adding the anti-aging agent. The dry ratio of the components of the raw materials and their proportioning ratios is:

[0026]

[0027] (2) Processes of mold washing, soaking in coagulant, and soaking in latex. The glove model is washed and preheated with soft water at 60°C-90°C on the line--hot air drying--soaking coagulant--drying--soaking pre-vulcanized latex--leaching, drying--crimping.

[0028] (3) Demolding process. Remove the mold after soaking the release agent powder water obtained in step (2). Get a semi-finished product.

[0029] (4) Vulcanization process. Use pre-heated water for vulcanization, water tem...

Embodiment 2

[0034] The preparation method two of safety latex gloves comprises the following steps;

[0035] (1) Raw material preparation. Heat the raw latex to 68°C after adding an accelerator vulcanizing agent, heat preservation and pre-vulcanization, stop vulcanization when the chloroform value reaches the third to third middle, and park it for use after adding the anti-aging agent. The dry ratio of the components of the raw materials and their proportioning ratios is:

[0036]

[0037] (2) Processes of mold washing, soaking in coagulant, and soaking in latex. The glove model is washed and preheated with soft water at 60°C-90°C on the line--hot air drying--soaking coagulant--drying--soaking pre-vulcanized latex--leaching, drying--crimping.

[0038] (3) Demolding process. Remove the mold after soaking the release agent powder water obtained in step (2). Get a semi-finished product.

[0039] (4) Vulcanization process. Use pre-heated water for vulcanization, water temperature 89°...

Embodiment 3

[0044] The preparation method three of safety latex gloves comprises the following steps;

[0045] (1) Raw material preparation. Heat the raw latex to 65°C after adding the accelerator vulcanizing agent, heat preservation and pre-vulcanization, stop vulcanization when the chloroform value reaches the third to the third middle, and stop the vulcanization after adding the anti-aging agent. The component of described raw material and proportioning number (dry ratio) thereof are:

[0046]

[0047] (2) Processes of mold washing, soaking in coagulant, and soaking in latex. After the glove model is cleaned and preheated with soft water at 69°C on the line, it is dried in hot air, soaked in coagulant, dried, soaked in (pre-vulcanized) latex, leached, dried, and crimped.

[0048] (3) Demolding process. Remove the mold after soaking the release agent powder water obtained in step (2). Get a semi-finished product.

[0049] (4) Vulcanization process. Use pre-heated water for vulcan...

Abstract

The invention relates to a method for preparing safe latex gloves, particularly to a method for preparing latex gloves free of nitrosamine. The method for preparing safe latex gloves of the invention comprises the processes of preparing latex, cleaning models, drying models, cleaning models, scouring process, soaking coagulating agent, drying, soaking latex, filtering, hot-water vulcanization and drying finished product. The aqueous solution in the hot-water vulcanization process comprises the following components in percentage by weight: 2 to 9% of glycerol, 1 to 3% of gel, 0.5 to 2% of cellulose, 2 to 9% of silicon dioxide, 0.05 to 5% of ethylene diamine tetraacetic acid, 0.02 to 2% of polysorbate 80, 1 to 30% of lauric acid, 2 to 3% of oleic alcohol, 2 to 7% of refined lanolin and the balance of softened water. In the latex gloves prepared according to the method of the invention, the residual amount of the N-nitrosamine of the nitrosamine is less than 0.01 mg / kg; therefore, the invention is safe and dependable to use and greatly reduces the cancer risk.

Description

technical field [0001] The invention relates to a preparation method of gloves, in particular to a preparation method of safety latex gloves. Background technique [0002] Among the latex products, gloves occupy a very important position. In addition to being used in industry, agriculture, fishery and household, they are also widely used in the medical field. my country, the United States, Japan, Malaysia and other countries all have glove production, and the product output, scope of application, manufacturers, and enterprise benefits are all considerable. The materials commonly used for gloves are latex and rubber. [0003] The main component of latex is polyisoprene, its structural formula: (CH2=C-CH=CH2)n, and its molecular weight is between 100,000 and 1.8 million. Latex has good film-forming properties and elasticity, high wet gel strength, good mechanical properties, high mechanical stability, and good stability. After latex is processed, it can achieve very excelle...
