[0026] Polyurethane emulsion is synthesized as follows:

[0027] First get 33 parts of polytetrahydrofuran glycol (PTMG) and add in the reaction kettle, under the situation of stirring, add 22 parts of isophorone diisocyanate (IPDI), then weigh 2.5 parts of dimethylol propionic acid (DMPA) and 3 Add 20 parts of diethylene glycol into the kettle, stir well, then add 20 parts of acetone and 0.02 parts of catalyst dibutyltin dilaurate in sequence. At 60-80°C, start timing and react for 3 hours. Then 1.6 parts of trimethylolpropane (TMP) and 25 parts of acetone were added, and the reaction was timed for 3 hours. After the reaction was completed, the temperature was lowered to below 50° C., and 33 parts of...

Abstract

The invention provides a pair of high-performance polyurethane-modified butyronitrile latex gloves and a preparation method thereof. According to the method, the chemical resistance of carboxyl butyronitrile latex can be enhanced by adopting a method of blending polyether urethane emulsion with butyronitrile latex. The butyronitrile gloves produced by adopting the impregnation forming technology of blended latex have the double characteristics of butyronitrile latex and polyurethane, as well as good chemical protection capability, and glove products can be produced on the existing butyronitrile latex glove production line.

Description

technical field [0001] The invention relates to a high-performance polyurethane-modified nitrile latex and a preparation method thereof, which belongs to the field of polymer materials. Background technique [0002] In recent years, with the improvement of enterprises' awareness of labor protection, enterprises have invested more and more in labor protection. The most obvious is the change of glove varieties, from traditional labor protection products (thread gloves) to synthetic chemical labor protection products (Latex gloves), the protective performance is gradually enhanced, the types of gloves are becoming more and more abundant, and the protection is becoming more and more targeted. At present, in many industries such as medical treatment, food, electronics, and photovoltaics, the protection of gloves is becoming more and more important. The main types of gloves include polyvinyl chloride gloves, natural rubber gloves, and nitrile gloves, among which nitrile gloves do ...
