Abstract

The invention discloses modified butyronitrile latex for gloves, relates to the technical field of high polymer materials, and mainly aims to solve the problem of poor mechanical properties of existing butyronitrile latex. The modified butyronitrile latex comprises the following raw materials: butyronitrile latex, a vulcanizing agent, an initiator, an emulsifier, a cross-linking agent and a modifier, the modifier is obtained by mixing modified polyethylene glycol and modified attapulgite clay and carrying out magnetic stirring, and the invention also discloses a preparation method of the modified butyronitrile latex for gloves. Gloves made of the modified butyronitrile latex have excellent tensile strength and elongation, particularly, the mechanical performance of the butyronitrile latex is further improved through joint use and synergistic interaction of the modified polyethylene glycol and the modified attapulgite clay, and the glove has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a modified nitrile latex for gloves and a preparation method thereof. Background technique [0002] Polymer materials are materials composed of compounds with relatively high molecular weight, including rubber, plastics, fibers, coatings, adhesives and polymer-based composite materials. Various polymer materials are widely used in our life and technology. . [0003] Nitrile latex is latex produced by emulsion polymerization of butadiene and acrylonitrile. Divided into high nitrile (35%-45%), medium nitrile (25%-33%), low nitrile (20%-25%) three kinds according to acrylonitrile mass percentage content, the application of nitrile latex is very extensive, especially It is used in the production of gloves. [0004] Generally speaking, the existing nitrile latex has poor mechanical properties and cannot meet the increasing demands of use. Contents of the invention [0...
