Description

Technical Field

[0001] The present invention relates to a rubber glove and a preparation method thereof, in particular to an anti-slip rubber glove and a preparation method thereof, belonging to the technical field of rubber products. Background Art

[0002] Rubber gloves are a type of gloves made of rubber sheets or films. They are classified into latex gloves and molded gloves according to rubber raw materials or manufacturing processes. Acid and alkali resistant gloves should be able to be used in sulfuric acid (density 1.32) or caustic soda solution (density 1.19) at 45°C. Electrical insulating gloves are divided into high-voltage and low-voltage types. High-voltage gloves can be used below 6000 volts (test voltage is 12000 volts). Low-voltage gloves can be used below 1000 volts. Medical gloves are divided into smooth surface and textured surface (textured gloves or wrinkled gloves). Due to their good protective effect and the ability to well protect the safety of users, they have been widely used in people's production and life.

[0003] At present, rubber gloves play an isolation and protection role for people's hands. However, sometimes the gloves are prone to slipping when contacting objects with water on the surface, which brings a lot of inconvenience to use, and sweating and bacteria breeding will occur inside the gloves after long-term wearing.

[0004] A Chinese patent, an anti-slip rubber glove with a frosted material (patent number: 202120328132.2), discloses an anti-slip rubber glove. The glove is fixedly installed with frosted rubber on the surface of the rubber glove body, thereby improving the anti-slip effect of the glove; and then by tearing the blocking block inside the rubber glove body, the air inside the rubber glove body can circulate with the outside through the breathable cloth, so it is more comfortable to use. This glove has a relatively complex structure, poor anti-slip effect and poor hand feeling when in use. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an anti-slip rubber glove with good anti-slip effect, simple structure and good hand feeling. At the same time, a preparation method of the anti-slip rubber glove is provided, and the method has simple process and no pollution.

[0006] To solve the above technical problems, an anti-slip rubber glove of the present invention includes a rubber glove body, and the rubber glove body includes a fingertip part and a palm part. Among them, anti-slip convex lines are provided on the outer surface of the fingertip part; anti-slip layers are provided on both the inner and outer surfaces of the rubber glove body.

[0007] In the above-mentioned anti-slip rubber glove, the rubber body is composed of a rubber base gum and an anti-slip solution, and the weight ratio of the rubber base gum to the anti-slip solution is 90:10.

[0008] The above-mentioned anti-slip rubber gloves, wherein the rubber base is one or more of nitrile rubber, natural rubber, fluororubber, silicone rubber, and polyurethane rubber.

[0009] In the above-mentioned anti-slip rubber gloves, the rubber base is preferably a mixture of nitrile rubber and natural rubber, and the nitrile rubber:natural rubber is 70:35, by weight ratio.

[0010] The above-mentioned anti-slip rubber gloves, wherein the anti-slip solution consists of the following components, measured in parts by weight:

[0011] 5-10 parts of nanosilver solution

[0012] Thickener 1-7 parts

[0013] 80-90 parts of water.

[0014] The above-mentioned anti-slip rubber gloves, wherein the anti-slip solution consists of the following components, measured in parts by weight:

[0015] 7 parts of nano silver solution

[0016] Thickener 5 parts

[0017] 88 parts water.

[0018] The above-mentioned method for preparing a non-slip rubber glove, wherein:

[0019] A. Evenly mix 5-10 parts of the weighed nanosilver solution, 1-7 parts of the thickener, and 80-90 parts of water to form a mixed solution; pour the mixed solution into a homogenizer, turn on the homogenizer, and stir for 20 minutes to form an anti-slip solution;

[0020] B. Add anti-skid solution to the rubber base, heating temperature range is 25℃-35℃, heating time is 5-10min;

[0021] C. Stir the rubber base glue and the anti-skid solution evenly at a stirring rate of 105-130r / min to obtain a mixed glue with a solid content of 20%-30%;

[0022] D. After the mold is dried, the mixed glue is impregnated into the mold; then it is dried at 130-150℃ for 30-40 minutes; it is naturally cooled to room temperature to form a glove blank, and the glove blank is removed from the mold;

[0023] E. Dipping and drying: Dip the formed glove blank into the anti-skid solution, so that the inner and outer surfaces are evenly coated with a layer of anti-skid solution, and then dry it at high temperature. The drying temperature is 80-100°C and the drying time is 18-25 minutes. After drying, it is naturally cooled to room temperature to form an anti-skid layer.

[0024] F. Repeat steps E two to three times to obtain the finished product, and that's it.

[0025] Advantages of the present invention: By adopting an improved formula and process, the gloves produced by this method have better anti-slip performance to protect the hands of users. The preparation method of a rubber glove with anti-slip function of the present invention has perfect operation and rigorous process, greatly improving the production quality of enterprises.
