Description

Technical Field

[0001] This invention relates to the field of rubber glove technology, and in particular to a non-slip rubber glove for a glove box and its preparation method. Background Technology

[0002] With the development of nuclear energy and nuclear technology, glovebox protective gloves have been widely used in fields such as nuclear fuel processing and nuclear waste disposal. These gloves may come into contact with glassware, metal tools, and chemical reagents during use. However, existing glovebox protective gloves have a smooth surface. While their grip performance is acceptable when dry, they tend to become slippery after contact with oily liquids such as chemical reagents. This reduces the coefficient of friction between the gloves and smooth objects, potentially causing slippage when gripping them and affecting the accuracy and stability of operations.

[0003] The above problems urgently need to be addressed. Summary of the Invention

[0004] This invention discloses a non-slip rubber glove for a glove box and its preparation method, aiming to solve the technical problems existing in the prior art.

[0005] The present invention adopts the following technical solution: According to a first aspect of the present invention, the present invention provides a non-slip rubber glove for a glove box, comprising a palm portion and an arm portion, the palm portion being used for gripping an object, the palm portion comprising a base layer and a plurality of raised structures or a plurality of recessed structures disposed on the base layer, the plurality of raised structures being used to increase the friction between the protective glove and a smooth object, and the plurality of recessed structures forming a local vacuum adsorption to guide the rapid discharge of chemical reagents to reduce slippage.

[0006] In one possible implementation, the protrusion structure is square, diamond-shaped, or hemispherical.

[0007] In one possible implementation, the recessed structure is mesh-shaped.

[0008] In one possible implementation, the thickness of the base layer of the anti-slip rubber glove is 0.6-1mm.

[0009] In one possible implementation, the height of the protrusion structure is 0.2-0.5 mm.

[0010] In one possible implementation, the height of the recessed structure is 0.1-0.2 mm.

[0011] According to a second aspect of the present invention, the present invention provides a method for preparing anti-slip rubber gloves for glove boxes, wherein calendered rubber compound sheets are cut into appropriate shapes, placed on a rubber glove mold, and after the mold is closed, the anti-slip rubber gloves are prepared by high-temperature vulcanization.

[0012] In one possible implementation, the vulcanization temperature is 155-170°C.

[0013] In one possible implementation, the vulcanization time is 5-20 minutes.

[0014] In one possible implementation, the vulcanization pressure is 15-20 MPa.

[0015] The technical solution adopted in this invention can achieve the following beneficial effects: This invention provides a non-slip rubber glove for a glove box and its preparation method, comprising a palm part and an arm part. The palm part is used for gripping objects, and the arm part is used to protect the wrist from contact with chemical reagents. The palm part includes a base layer and raised or recessed structures disposed on the base layer. By adding non-slip textures to the surface of the palm part of the rubber glove, this invention can increase the friction between the rubber glove and smooth objects (such as glassware and metal tools), helping users to better control objects and reduce hand fatigue. The non-slip textures can form local vacuum adsorption, guiding liquids such as chemical reagents to drain quickly, reducing slippage and improving grip stability in wet and slippery environments.

[0021] With the development of nuclear energy and nuclear technology, glove box protective gloves have been widely used in fields such as nuclear fuel processing and nuclear waste disposal. These gloves may come into contact with glassware, metal tools, and chemical reagents during use. However, existing glove box protective gloves have a smooth surface. While their grip is acceptable when dry, they easily become slippery after contact with oily liquids, potentially causing slippage and affecting the accuracy and stability of operations. To address these problems, this invention provides a non-slip rubber glove for glove boxes and its preparation method.

[0022] Figure 1 The diagram shown is a schematic representation of the overall structure of an anti-slip rubber glove provided in an embodiment of the present invention; as shown... Figure 1As shown, the anti-slip rubber glove includes a palm part 1 and an arm part 2. The palm part 1 is used to grip objects. The arm part 2 and the palm part 1 constitute the entire anti-slip rubber glove for protection against radiation and chemical hazards to the hands. The palm part 1 includes a base layer 11 and raised structures 12 or recessed structures 13 disposed on the base layer 11. The raised structures 12 are used to increase the friction between the protective glove and smooth objects. The recessed structures 13 form a local vacuum adsorption, which guides liquids such as chemical reagents to be discharged quickly, reducing slippage and thus playing an anti-slip role.

[0023] In one possible implementation, the protruding structure is square, diamond-shaped, or hemispherical, while the recessed structure is grid-shaped.

[0024] Figure 2 The image shown is a side view of the raised structure and base layer of an anti-slip rubber glove according to an embodiment of the present invention; as shown... Figure 2 As shown, when the raised structure 12 is square, a square pattern mold is designed on the palm (finger area). The mold has a mirror-symmetrical left and right hand structure, and anti-slip patterns are made in the lower cavity of the mold. Calendered rubber compound sheets are cut into suitable shapes and placed on the mold. After the mold is closed, it undergoes high-temperature vulcanization at 170℃ for 10 minutes and a vulcanization pressure of 16MPa. After high-temperature vulcanization, anti-slip patterns are formed on the surface of the rubber glove.

[0025] Figure 3 The image shown is a side view of the diamond-shaped protrusion and base layer of an anti-slip rubber glove according to an embodiment of the present invention; as shown... Figure 3 As shown, when the raised structure 12 is diamond-shaped, a diamond-shaped pattern mold is designed on the palm (finger area). The mold has a mirror-symmetrical left and right hand structure, and anti-slip patterns are made in the lower cavity of the mold. Calendered rubber compound sheets are cut into suitable shapes and placed on the mold. After the mold is closed, high-temperature vulcanization is performed at 165℃ for 10 minutes and at a pressure of 18MPa. After high-temperature vulcanization, anti-slip patterns are formed on the surface of the rubber glove.

[0026] Figure 4 The image shown is a side view of the hemispherical protrusion and base layer of an anti-slip rubber glove according to an embodiment of the present invention; as shown... Figure 4 As shown, when the raised structure 12 is hemispherical, a hemispherical texture mold is designed on the palm part (finger area). The mold has a mirror-symmetrical left and right hand structure, and anti-slip texture is made in the lower cavity of the mold. Calendered rubber compound sheets are cut into suitable shapes and placed on the mold. After the mold is closed, it undergoes high-temperature vulcanization at 160℃ for 12 minutes and a vulcanization pressure of 17MPa. After high-temperature vulcanization, anti-slip texture is formed on the surface of the rubber glove.

[0027] Figure 5 The image shown is a side view of the mesh-type recess and base layer of an anti-slip rubber glove according to an embodiment of the present invention. Figure 5 As shown, when the recessed structure 13 is a grid type, a grid-pattern mold is designed on the palm (finger area). The mold has a mirror-symmetrical left and right hand structure, and anti-slip texture is made in the lower cavity of the mold. Calendered rubber compound sheets are cut into suitable shapes and placed on the mold. After the mold is closed, it undergoes high-temperature vulcanization at 165℃ for 10 minutes and a vulcanization pressure of 16MPa. After high-temperature vulcanization, anti-slip texture is formed on the surface of the rubber glove.

[0028] In one possible implementation, the thickness of the anti-slip rubber glove base layer 11 is 0.6-1 mm. A 0.6-1 mm thick anti-slip rubber glove provides basic cut and puncture resistance, and offers more effective protection when in contact with chemical reagents.

[0029] In one possible implementation, the height of the raised structure 12 is 0.2-0.5mm. Square, diamond, or hemispherical patterns are designed on the palm part of the anti-slip rubber glove, i.e., the palm and finger area. The raised structure 12 forms square, hemispherical, or diamond-shaped protrusions. This raised structure can increase the friction between the rubber glove and smooth objects (such as glassware, metal tools, and chemical reagents) when in contact with tools and materials such as glassware, metal tools, and chemical reagents, helping the user to better control the objects and reduce hand fatigue. When in contact with oily liquids such as chemical reagents, these raised structures can increase friction, guide the liquids such as chemical reagents to be discharged quickly, reduce slippage, and improve grip stability in wet and slippery environments.

[0030] In one possible implementation, the height of the recessed structure 13 is 0.1-0.2 mm. A grid-like texture is designed on the palm part of the anti-slip rubber glove, i.e., the finger area. This recessed structure 13 can increase the friction between the rubber glove and smooth objects (such as glassware, metal tools, and chemical reagents) when in contact with tools and materials such as glassware, metal tools, and chemical reagents, helping the user to better control the objects. When in contact with oily liquids such as chemical reagents, these recessed structures 13 can form a local vacuum adsorption, which improves the grip stability in wet and slippery environments.

[0031] According to a second aspect of the present invention, the present invention provides a method for preparing anti-slip rubber gloves for glove boxes, wherein calendered rubber compound sheets are cut into appropriate shapes, placed on a rubber glove mold, and after the mold is closed, they are prepared by high-temperature vulcanization, wherein the vulcanization temperature is 155-170°C, the vulcanization time is 5-20 min, and the vulcanization pressure is 15-20 MPa.

[0032] When the vulcanization temperature is 170℃, the vulcanization time is 10min, and the vulcanization pressure is 16MPa, a square protrusion is formed on the palm after high-temperature vulcanization.

[0033] When the vulcanization temperature is 165℃, the vulcanization time is 10min, and the vulcanization pressure is 18MPa, a diamond-shaped protrusion is formed on the palm after high-temperature vulcanization.

[0034] When the vulcanization temperature is 160℃, the vulcanization time is 12min, and the vulcanization pressure is 17MPa, a hemispherical protrusion is formed on the palm part 1 after high-temperature vulcanization.

[0035] When the vulcanization temperature is 165℃, the vulcanization time is 10min, and the vulcanization pressure is 16MPa, a grid-like protrusion is formed on the palm part 1 after high-temperature vulcanization.

[0036] Applying this non-slip rubber glove to a glove box can help users better control objects by adding non-slip textures to the surface of the existing glove box protective gloves.

[0037] The above describes embodiments of the present invention. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
