Abstract

The invention discloses a preparation method of a SiO2 modified natural latex high-isolation medical glove. According to the preparation method, natural plant extract liquid and nano SiO2 are uniformly dispersed in natural latex, and are subject to pre-vulcanization, linkage forming, water vulcanization and the like to prepare the high-isolation medical glove. The high-isolation medical glove hasthe beneficial effects that charges carried by the natural plant extract liquid components added in the high-isolation medical glove are mutually adsorbed with virus molecules, virus is adsorbed to the surface of a film, the virus is prevented from penetrating through the film, and nano SiO2 particles can be uniformly dispersed among the latex particles, so that the dispersity of the nano SiO2 particles and the density of the adhesive film are improved, the hydroxyl aldehyde is condensed in the forming process of the adhesive film, and the density of the high-isolation medical glove is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a SiO 2 A preparation method of modified natural rubber latex high-isolation medical gloves. Background technique [0002] Since the 1980s, with the emergence of human immunodeficiency virus (HIV) and the understanding of the transmission route of blood diseases, people engaged in medical, nursing and other health fields have often worn medical gloves to protect them from possible infection or to protect hands from exposure to harmful substances. Common medical gloves are generally made of natural latex collected from the three-leaf latex tree. It has a series of good properties, such as good film-forming properties of natural latex, and natural latex gloves have high intrinsic elasticity. And it has considerable sensitivity when grabbing objects. [0003] However, based on the inherent characteristics of natural latex and the inadequacies of traditional medical glove production...
