Problems solved by technology

[0003] Since latex gloves are thin products, it is impossible to add many reinforcing agents, and the restrictions on anti-aging agents in medical products make the products generally have the disadvantages of not good enough performance, short storage period and easy aging and stickiness. way, the latex solution is often contaminated, greatly affecting the quality of latex gloves

Abstract

The invention provides a manufacturing method of ultrathin anti-aging medical latex gloves. The method comprises the following steps: 1, preparing a latex solution, 2, treating and washing a mold, 3,spraying the latex solution in the step 1 to a dried glove forming mold by using a spray gun, 4, carrying out primary drying on the latex solution on the glove forming mold: carrying out primary drying on the glove forming mold coated with the latex solution through a drying oven, spraying the latex solution to the glove forming mold dried for the first time through a spray gun, and then, drying the glove forming mold for the second time through the drying oven, 5, carrying out vulcanization and anti-sticking release treatment, and 6, carrying out demolding, and carrying out aging for 35-40 hours at the temperature of 110-150 DEG C by adopting hot air. Compared with existing gloves, the gloves manufactured through the method have the advantages that the ageing resistance is obviously improved, and the gloves have excellent mechanical properties; the latex gloves obtained by improving the spray gun have higher mechanical strength than latex gloves manufactured through an existing manufacturing method; and the gloves manufactured on the basis of the method are more stable in quality.

Description

technical field [0001] The invention relates to the field of gloves, in particular to a method for manufacturing ultra-thin anti-aging medical latex gloves. Background technique [0002] Natural latex gloves have good isolation protection and can effectively prevent the hazards of germs and chemicals, so they have been widely used in the 1980s. However, some people have allergic reactions to natural rubber latex, and Because natural latex gloves are not resistant to solvents and chemicals, people have to develop a variety of gloves made of synthetic materials, such as nitrile, neoprene, PVC, polyurethane gloves and so on. Among them, nitrile gloves are very popular because of their comfortable feel, good strength and oil resistance. [0003] Since latex gloves are thin products, it is impossible to add many reinforcing agents, and the restrictions on anti-aging agents in medical products make the products generally have the disadvantages of not good enough performance, shor...
