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] The disposable nitrile glove with the performance of reducing ozone oxidation of the present invention is prepared by the preparation method comprising the following steps:

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

[0076] Step 2) Prepare the nitrile latex for dipping to generate the middle layer adhesive film 2-2: respectively weigh 100 parts of nitrile rubber latex, 1.1 part of potassium hydroxide...

Embodiment 2

[0091] The basic structure of the hand mold used in this embodiment is as follows 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 ceramic insulating layer 1-1 of the outer layer of the hand mold is a metal copper 1-2 with a thickness of 2.0 mm. The container material of the nitrile latex for forming 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 a 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 example are the same as those of Example 1.

[0093] The preparation method of carboxylated nitrile rubber latex and the modification method of carboxylated nitrile rubber latex are the same as in Example 1.

Abstract

The invention discloses a disposable nitrile glove capable of alleviating ozone oxidation. The disposable nitrile glove is composed of three layers of adhesive films, namely an inner layer of adhesive film, a middle layer of adhesive film and an outer layer of adhesive film. The latex that forms the film is mainly composed of nitrile rubber and related auxiliary materials. Nano-manganese dioxide is added to the outer film, polylysine is added to the inner film, and nano-iron powder is added to the middle film. The disposable nitrile glove is also provided with an acid-base indicator strip, an organic solvent indicator strip, sweat and its water vapor discharge structure. The invention also discloses a preparation method of the disposable nitrile gloves capable of alleviating ozone oxidation. The disposable nitrile gloves made by the preparation method of the present invention can slow down the influence of ozone on the strength of the film, reduce hand itching during wearing, indicate the risk of damage, indicate whether it is contaminated with pollutants such as acid-base, organic solvents, and reduce Or to avoid the accumulation of sweat on the hands and its water vapor.

Description

technical field [0001] The invention belongs to the field of safety protection, and relates to colloidal gloves for hand protection, in particular to a disposable nitrile glove with ozone oxidation reducing performance 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 health, beauty salons, food processing, chemical biology, etc., and play an indispensable role in protecting hands and preventing cross infection supplies. Because nitrile rubber does not contain protein, it will not cause allergic reactions, and at the same time it has the properties of antistatic, aging resistance and oil resistance. 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] Bu...
