Description
Technical Field
The invention belongs to the technical field of labor protection articles, and particularly relates to a preparation method of water-based butyl gloves without linings.
Background
The butyl rubber gloves are commonly used for the operation of glove boxes, anaerobic boxes, incubators and operation boxes, and have better anti-acid and anti-alkali effects on chemicals. With the expansion of the application range of the butyl gloves, the butyl gloves are also used for the action environments of overhauling a reaction kettle, overhauling a mail box and the like at present. The existing butyl rubber gloves have certain anti-skid property, but the anti-skid property is greatly reduced in water or oil, so that the parts are difficult to grab, and especially the parts are difficult to grab during screwing or unscrewing operation.
In addition, the latex of the existing butyl gloves is non-aqueous butyl latex, a large amount of organic solvent is needed during gum dipping, and the use of the organic solvent is not environment-friendly, has certain toxicity and has certain harm to the environment and human bodies.
Moreover, the existing butyl gloves generally have linings or frameworks, the preparation process is complicated, bulges are easily generated on the surfaces of the produced gloves, and the gloves are poor in hand softness. For example, chinese patent document CN109503963A, published in 2019, 03.22.9, discloses a butyl latex and a method for preparing the same and a method for preparing gloves using the same, wherein the publication proposes "dipping in hot water, dipping in a coagulant, dipping in latex, leaching, sleeving a framework material, dipping in latex twice, drying, curling, demoulding, inspecting, repairing, loading on a car, vulcanizing, treating with water, inspecting for air tightness, drying, inspecting for appearance, batching, and inspecting and packaging". Although butyl latex gloves are prepared through a series of preparation steps in the prior art, the process is easy to cause the rubber surface to bulge, and the softness of the gloves is poor. Also, for example, chinese patent document CN103965554B, published 2016, 07, 06, discloses a butyl latex, a method for preparing the same, and a method for preparing gloves prepared from the same, wherein the butyl latex comprises a glove lining and an outer dipping layer of a blend emulsion material, and the outer dipping layer of a polymer blend material comprises the following components: the high-molecular blending alloy material comprises a main body of a high-molecular blending alloy material, a vulcanizing agent, an accelerant and a vulcanizing activator, wherein the mass parts are as follows: the main body of the polymer blending alloy material is as follows: vulcanizing agent: accelerator (b): vulcanization activator =100:0.5-5:0-2: 1-3; the main body of the polymer blending alloy material comprises 60-100% of butyl rubber and 0-40% of other polymer materials; the other high polymer materials are PVC, PE, phenolic aldehyde or nitrile rubber', the butyl gloves with linings prepared by the prior art have chemical protection performance, but the gloves have poor softness and flexibility and cannot adapt to operation with strong flexibility.
In summary, the existing butyl gloves have the problems of poor gripping force under the water or oil environment, easy bulge on the rubber surface, and poor softness and flexibility, and the adopted non-aqueous butyl latex is not environment-friendly and has no expected effect on surface wear resistance. For this reason, a new technical solution is needed to solve the above technical problems.
