Abstract

The invention relates to an organosilicon-modified acrylate emulsion and a preparation method of a coating agent for powder-free gloves. The preparation method comprises the following steps of: preparing the organosilicone-modified acrylate emulsion; adding the organosilicon-modified acrylate emulsion into a stirred tank; adding a wetting agent for base materials, a germicide and deionized water under constant mixing; then adding a foam killer, a thickening agent, a pH value conditioner after evenly mixing; and discharging after evenly mixing. The solid content of the coating agent of the organosilicon-modified acrylate emulsion is between 10% and 30%; the surface tension is not more than 35mN/m; and the viscosity is between 100 mPa.s and 1000mPa.s; and the pH value is between 7 and 9. The coating agent is diluted with the deionized water according to a rate of 1:19, is leached by a hand model coated with a disposable glove and then is dried at the temperature between 100 DEG C and 150 DEG C. Finally the powder-free gloves processed by the coating agent are formed after demolding.

Description

technical field [0001] The invention relates to a silicone-modified acrylate emulsion and a preparation method for a coating agent for manufacturing powder-free gloves, which can be used for manufacturing various powder-free gloves. Background technique [0002] Disposable gloves, such as natural rubber gloves, nitrile rubber gloves and PVC gloves, are widely used in production, living and medical fields. However, due to the nature of the polymer material itself, if no surface treatment is carried out, the inner surface of these disposable gloves is easy to stick and cannot be taken off from the hand mold. Therefore, surface treatment of the inner surface of gloves is a very important step in glove production. [0003] The traditional surface treatment method is to coat a layer of powdery materials such as starch and talcum powder on the inner surface of the glove, but these powdery materials are easy to fall off, which is easy to cause wound infection in the medical field,...
