Abstract

The invention discloses a PVC glove with strong ductility and a preparation method thereof. The PVC glove is prepared by taking high-dispersity powder PVC paste resin as a raw material, when the PVC paste resin is prepared, induced decomposition of a water-soluble redox initiator is adopted, and the initiator not only contains amino and hydroxyl, but also can directly introduce a ductile group forimproving the material on the premise of not specially treating the material; calcium peroxide serving as a reducing agent reacts with sodium carbonate to generate calcium carbonate serving as a filling agent in a blending system, so that the cost can be saved, the tensile property of PVC resin is further changed, an environment-friendly plasticizer without benzene rings is adopted, environmentalpollution is reduced, the plasticizer serving as a raw material for preparing the glove is cost-saving and environment-friendly, and the PVC glove with strong ductility can prolong the service life of the glove and meet the use requirements of high-requirement industries.

Description

technical field [0001] The invention belongs to the field of plastic glove production, in particular to a PVC glove with strong ductility and a preparation method thereof. Background technique [0002] Disposable PVC gloves are an emerging industry and have gradually entered the public's field of vision in recent years. Disposable gloves mainly include latex gloves, nitrile gloves, PVC gloves and PE gloves. Among them, latex gloves, nitrile gloves, and PVC gloves are stable in quality, good in protection, and have a wide range of applications, occupying most of the market share; although PE gloves are cheap, they have disadvantages such as poor scalability, easy damage, and affect operation after wearing. It is a low-end product, mainly used in the catering field, with a limited market share, and it is difficult to develop into a mainstream product of disposable gloves. Compared with nitrile gloves, PVC gloves have more prominent cost advantages, and are comfortable to wea...
