Abstract

The invention relates to a preparing method of once butyronitrile glazing and twice butyronitrile foaming gloves. The preparing method includes the steps that a glove blank is pre-heated, then is soaked in a coagulant, and then soaked in a first impregnating adhesive and a foaming adhesive, wherein the first resin impregnating adhesive and a foaming adhesive are butyronitrile mucilage; and the glove blank is soaked in the coagulant, pre-baking, water washing, and vulcanizing are conducted, and the once butyronitrile glazing and twice butyronitrile foaming gloves are obtained. The gloves obtained through the method not only have wear resistance and heat insulation, oil stain resistance and acid-alkali resistance and anti-corrosion properties, but also have slow resilience and shock absorption performance.

Description

technical field [0001] The invention relates to a preparation method of one-pass nitrile smooth surface and two-pass nitrile foam gloves, and belongs to the technical field of labor protection products. Background technique [0002] Protective gloves are used in special labor occasions to protect human hands. The earliest cotton thread and animal leather gloves have been developed into protective gloves of various materials and properties. Due to different labor occasions, the requirements for glove performance are also different. not exactly. For example, general dipped gloves can be widely used in petrochemical, paint printing, agriculture, animal husbandry, automobile machinery maintenance and other industries; but there are also some special requirements, such as requiring shockproof function. The anti-vibration gloves of the previous application are obtained by means of dotting beads, or can be further prepared by impregnating rubber. However, the beading process in th...
