Description of the Related Art Heretofore, rubber gloves made of natural rubber or synthetic rubber are extremely difficult to handle because their surfaces adhere to each other, and when they contact each other, they adhere to each other. Therefore, in order to solve this problem, the outer surface of the rubber glove is subjected to a powder treatment such as sprinkling fine powder such as talc or mica, or the rubber glove is immersed in chlorine water to form a layer of chlorinated rubber on the surface. For example, the chlorine treatment to form the was done.

る。A method for treating a surface of a rubber glove according to the present invention comprises:
The method is characterized in that a liquid comprising a rubber latex containing a polymer flocculant is applied, and then the applied surface is dried and washed with water. As described above, in the present invention, since the liquid of the rubber latex containing the polymer flocculant is applied to the surface of at least the finger portion of the rubber glove, and the coated surface is dried and washed with water, the polymer flocculant is thereby added. Since a part or all of this is eluted, the surface becomes a floc state, that is, a state having extremely fine irregularities.
Therefore, by performing vulcanization by a conventional method,
A rubber glove having fine irregularities on the surface can be easily obtained. Since this rubber glove has a non-adhesive surface, it can be directly applied to a special purpose such as for dentistry.

で、30分から60分攪拌し続け、調製を完了する。Next, the coated surface is vulcanized under desired conditions to obtain a product. The liquid used in the above step is prepared, for example, as follows. That is, the polymer coagulant filtered with a stainless steel wire mesh or a fiber filter cloth is stirred with a stirrer for a while. Next, 0.1 to 1.0 parts by weight of a stabilizer is added together with the rubber latex per 100 parts by weight of the rubber solid content. After some time, the protective colloid was added to the rubber solids.
0.1 to 1.0 parts by weight per 100 parts by weight is added and further stirred, and subsequently, a vulcanizing agent, a vulcanization accelerator, an antioxidant and an optional compounding agent according to the characteristics of the rubber are added. continue,
0.1 to 100 parts by weight of rubber solid content of any polymer flocculant
Add 3.0 parts by weight. At this time, the rubber particles agglomerate and precipitate when left to stand, so stirring is further continued. Then, the aggregation of the rubber particles is broken and flocs are generated. Therefore, the stirring is continued for 30 to 60 minutes to complete the preparation.

ば良い。The drying and washing conditions in the above steps can be arbitrarily changed according to the characteristics of the rubber latex used, but a washing treatment (water washing treatment) is essential. By elution of a part or all, the coated surface becomes a flock state, that is, a state having extremely fine irregularities. The vulcanization conditions in the above steps may be arbitrarily selected by a conventional method according to the characteristics of the rubber latex used.

することが可能である。As described above, according to the present invention, the liquid of the rubber latex containing the polymer coagulant is applied to the surface of at least the finger portion of the rubber glove, and then the applied surface is dried and washed with water. By doing so, it is possible to obtain a rubber glove that is easy to grip an article during use, has a non-adhesive surface, and has fine irregularities on the surface. Since the rubber glove obtained by the method of the present invention has fine irregularities on the surface, it can contribute to improving workability particularly for dentistry.
