Problems solved by technology

It is easily affected by corrosive gases such as ozone, which reduces the strength of nitrile rubber and deteriorates the protective effect; due to long-term wearing, hand itching cannot be effectively treated; because nitrile rubber gloves are thin, when pierced or broken, hands The entire skin will be completely exposed to the dangerous environment, which is not conducive to the effective protection of the hands; there is no pollutant contact mark on the outer layer of the nitrile gloves, which is easy to cause cross-contamination between the contaminated part and the clean part, which is not conducive to effective protection; The airtightness of nitrile rubber itself makes it impossible to discharge the sweat and water vapor produced by the hands in time when worn for a long time, causing the skin of the hands to soak and turn white and other discomfort, which affects the accuracy of the operation

Embodiment 1

[0074] Adopt the preparation method that comprises the following steps to prepare the disposable nitrile gloves that have mitigation ozone oxidation performance of the present invention:

[0075] Step 1) prepare the dipping nitrile latex that generates the inner layer film 2-1: take by weight respectively 100 parts of nitrile rubber emulsion, 0.9 part of potassium hydroxide, 0.009 part of Tween 80 (surfactant), positive 0.08 parts of heptanol (defoamer), 1.1 parts of zinc oxide, 0.41 parts of sulfur, 3.1 parts of titanium dioxide, 0.06 parts of zinc diethyldithiocarbamate (vulcanization accelerator), 260 parts of water. After mixing, stir clockwise for 60 minutes, the stirring speed is 90 rpm, grind 6 times with a colloid mill, and the pH value of the obtained latex is 7.6 to 8.2;

[0076] Step 2) prepare and generate the dipping nitrile latex of middle layer film 2-2: take by weight 100 parts of nitrile rubber emulsion respectively, 1.1 parts of potassium hydroxide, 0.013 par...

Embodiment 2

[0091] The basic structure of the hand model used in this embodiment is as figure 2 As shown, the outer layer of the hand mold is a ceramic insulating layer 1-1 with a thickness of 2.0 mm, and the metal copper 1-2 with a thickness of 2.0 mm is close to the outer ceramic insulating layer 1-1 of the hand mold. The container material of the nitrile latex that generates the inner layer film 2-1 is 304 stainless steel. Use a DC power supply to provide an electrostatic field. The negative pole of the DC power supply is connected to the metal copper 1-2 of the hand mold, the positive pole of the DC power supply is connected to the 304 stainless steel container, and the voltage of the DC power supply is set to 100V.

[0092] The steps of the preparation method of this embodiment are the same as that of Example 1.

[0093] The modification method of carboxyl nitrile butadiene rubber latex preparation method and carboxyl nitrile butadiene rubber latex is identical with embodiment 1. ...

Embodiment 3

[0096]Adopt the preparation method that comprises the following steps to prepare the disposable nitrile gloves that have mitigation ozone oxidation performance of the present invention:

[0097] Step 1), step 3) to step 5), step 7) to step 9) are identical with embodiment 1;

[0098] Step 2) prepare and form the dipping nitrile latex of middle layer film 2-2: under the protection of nitrogen, take by weight 100 parts of nitrile rubber emulsion respectively, 1.1 parts of potassium hydroxide, Tween 80 (surfactant) 0.013 parts, 0.091 parts of n-heptanol (defoamer), 0.9 parts of zinc oxide, 0.59 parts of sulfur, 1.8 parts of titanium dioxide, 0.11 parts of zinc diethyldithiocarbamate (vulcanization accelerator), 0.005 parts of nano-iron powder, The shape of the nano-iron powder is spherical, its average diameter is 20-30 nanometers, and 230 parts of water. After mixing, stir counterclockwise for 50 minutes, the stirring speed is 100 rpm, and grind 5 times with a paint grinder;

Abstract

The invention discloses a disposable butyronitrile glove with ozone oxidation reducing performance. The disposable butyronitrile glove is composed of three layers of adhesive films, namely an inner-layer adhesive film, a middle-layer adhesive film and an outer-layer adhesive film. The latex for generating the adhesive films is mainly composed of nitrile rubber and related auxiliary materials thereof. Nanometer manganese dioxide is added into the outer-layer adhesive film, polylysine is further added into the inner-layer adhesive film, and nanometer iron powder is added into the middle-layer adhesive film. The disposable butyronitrile glove is further provided with an acid-base indicating strip, an organic solvent indicating strip and a sweat and water vapor discharging structure. The invention further discloses a preparation method of the disposable butyronitrile glove with the ozone oxidation reducing performance. The disposable butyronitrile gloves prepared by the preparation methoddisclosed by the invention can relieve the influence of ozone on the strength of the adhesive films, relieve hand itching in the wearing process, prompt the damage risk, indicate whether the gloves are contaminated by pollutants such as acids, alkalis, organic solvents and the like or not, and reduce or avoid accumulation of hand sweat and water vapor thereof.

Description

technical field [0001] The invention belongs to the field of safety protection, relates to a rubber glove used for hand protection, in particular to a disposable nitrile glove capable of reducing ozone oxidation and a preparation method thereof. Background technique [0002] Nitrile gloves are mainly processed from nitrile rubber. They are used in scientific research industries such as medical treatment, medicine and hygiene, beauty salons, food processing, chemical biology, etc., to protect hands and prevent cross-infection. supplies. Because nitrile rubber does not contain protein, it will not cause allergic reactions. At the same time, it has antistatic, aging and oil resistance properties. Its shape is designed according to the shape of the human hand, with greater flexibility and better stretching Performance and puncture resistance, high tensile strength and good wear resistance, widely used. [0003] But nitrile gloves also have certain problems in use. It is easil...
