A kind of breathable surgical gloves and preparation method thereof

Abstract

The invention provides a pair of breathable surgical gloves and a preparation method thereof. The preparation method comprises the steps of mixing a waterborne polyurethane resin material with water, and stirring to obtain mixed liquid, wherein the waterborne polyurethane resin material is prepared from 15-50 parts by weight of polyurethane and 50-85 parts by weight of water, the polyurethane is prepared from a polyalcohol polymer, diisocyanate, a waterborne chain extender, a hydrophilic agent, a cross-linking agent, a catalyst, a salt forming agent and an organic solvent according to a mass ratio of (30-50) to (15-25) to (1-10) to (0.5-20) to (0.1-10) to (0.1-0.5) to (1-10) to (1-10), and the polyalcohol polymer is selected from polyether polyalcohol and / or polyester polyalcohol; dipping hand moulds into the mixed liquid, winding lips after films are formed, and demoulding to obtain the breathable surgical gloves, wherein during dipping, the temperature of the hand moulds is less than or equal to 60 DEG C, and the dipping time is 20-60s; the film formation temperature is 100-130 DEG C, and the film formation time is 2-4min. The breathable surgical gloves have excellent discharge moisture permeability as well as higher tensile strength and elongation at break.

Description

technical field

[0001] The invention relates to the technical field of surgical gloves, in particular to a breathable surgical glove and a preparation method thereof. Background technique

[0002] At present, most medical surgical gloves are made of natural latex. Natural rubber refers to the elastic solid made of natural latex collected from Hevea brasiliensis through coagulation, drying and other processing procedures. Natural rubber is a natural polymer compound with cis-1,4-polyisoprene as the main component, and its rubber hydrocarbon (cis-1,4-polyisoprene) content is more than 90%, and it also contains A small amount of protein, fatty acid, sugar and ash etc. However, in order to reduce the risk of allergies to patients and medical staff, more and more hospitals expect to phase out natural latex products including surgical gloves. At present, the relatively mature synthetic materials in the field of surgical glove applications are neoprene and isoprene rubber (IR). ...
