Abstract

The invention relates to a preparation method of butyronitrile false foaming anti-skid gloves. The method comprises the step that paraffin oil plasticizer poor in compatibility with butyronitrile latex is added in the butyronitrile latex, wherein the additive amount of the paraffin oil plasticizer is 2.4%-12.2% of butyronitrile latex by mass. Accordingly, on one hand, the advantage of the plasticizer capable of increasing the softness, oil resistance and abrasion resistance of rubber products is applied; on the other hand, by means of the advantage of being poor in compatibility with butyronitrile, the paraffin oil plasticizer forms the certain occupying effect in butyronitrile glue, in the heating prevulcanization process, separation or bleeding is conducted, pit-shaped structures in different degrees are formed on the glove glue surfaces, the roughness of the glove glue surfaces is increased to a certain extent, and the grasp anti-skid property of the gloves is enhanced. Due to the fact that the pit-shaped structures have the advantage of increasing the softness of the butyronitrile gloves, the pit-shaped structures are different from communicated foaming holes formed by foamingglue, the water resistance and oil resistance cannot be weakened, and the gloves are false foaming butyl rubber gloves approximating foaming but not virtually foaming.

Description

technical field [0001] The invention relates to a preparation method of gloves, in particular to a preparation method of nitrile fake foam anti-skid gloves. Background technique [0002] The preparation method of rubber gloves is generally to form a layer of rubber layer after the textile glove embryo is impregnated with natural latex, synthetic latex, etc. on the surface, which can protect the user's hands. Nitrile latex is a kind of latex with high polarity. The nitrile rubber formed after curing has excellent water resistance, oil resistance and abrasion resistance. Therefore, nitrile gloves are recognized by consumers. Applications in the preparation of gloves are increasing. [0003] However, although nitrile gloves are water-resistant, oil-resistant and wear-resistant, their hand feeling is relatively hard, and the user's wearing comfort is relatively poor; although nitrile foam gloves have better softness, many connected pores will be formed by foaming, making the gl...
