Problems solved by technology

Because there is no pollutant contact mark on the outer layer of nitrile gloves, it is easy to cause cross-contamination between the contaminated part and the clean part, which is not conducive to effective protection; The steam, etc. cannot be discharged in time, causing discomfort such as soaking and whitening of the skin of the hands, which affects the accuracy of the operation; due to long-term wearing, the itching of the hands cannot be effectively treated; because the nitrile rubber gloves are thin, when they are pierced or broken, the hands The skin will be completely exposed to the dangerous environment, which is not conducive to the effective protection of the hands; it is easily affected by corrosive gases such as ozone, which will reduce the strength of nitrile rubber and deteriorate the protective effect

Embodiment 1

[0074] The disposable nitrile gloves of the present invention are prepared by a preparation method comprising the following steps:

[0075] Step 1) prepare the nitrile latex for dipping to generate the inner layer adhesive film 2-1: weigh 100 parts of nitrile rubber latex, 0.82 part of potassium hydroxide, 0.0079 part of Tween 80 (surfactant) according to parts by weight, 0.086 parts of heptanol (defoamer), 1.11 parts of zinc oxide, 0.383 parts of sulfur, 2.88 parts of titanium dioxide, 0.0716 parts of zinc diethyldithiocarbamate (vulcanization accelerator), 259 parts of water, after mixing, stir clockwise for 71 parts minutes, the stirring speed is 89 rpm, and the colloid mill is used for grinding 4 times; the pH value of the obtained latex is 7.09-7.61;

[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, 1.08 parts of potassium hydroxide, 0.0128 parts of Tween 80 (surfact...

Embodiment 2

[0094] The hand model used in this embodiment is a hand model capable of producing sweat and its water vapor discharge structure 2-1-2. Its basic structure is as follows: Figure 8 As shown, the surface of the hand mold has strip-shaped depressions 1-3, the cross-section of the strip-shaped depressions 1-3 is a semi-ellipse, the long diameter of the semi-ellipse is 0.62 mm, the short diameter is 0.51 mm, and the short diameter is 0.51 mm. perpendicular to the film surface. The distribution of the strip-shaped depressions 1-3 on the surface of the hand mold, such as Figure 9 shown, Figure 9 The right picture of is a front view of the hand mold capable of producing sweat and its water vapor discharge structure 2-1-2, and the left picture is a rear view. Each finger is provided with 6 strip-shaped depressions 1-3, a total of 30 strip-shaped depressions 1-3 are set on the surface of the hand mold, and each strip-shaped depression 1-3 extends to the wrist of the hand mold. The...

Abstract

The invention discloses a disposable nitrile glove. The nitrile glove is provided with an acid-base indicator strip and an organic solvent indicator strip, and 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. film. The latex for forming the film is mainly composed of nitrile rubber and related auxiliary materials. The inner layer adhesive film is added with polylysine and dopa, the middle layer adhesive film is added with nano iron powder, and the outer layer adhesive film is added with nano manganese dioxide. The nitrile glove is also provided with a structure for expelling sweat and its water vapor. The invention also discloses a preparation method of the disposable nitrile gloves. The disposable nitrile gloves made by the preparation method of the present invention can indicate whether they are contaminated with pollutants such as acid and alkali, organic solvents, etc., reduce or avoid the accumulation of sweat and water vapor on the hands, relieve itching of the hands during wearing, and indicate damage. risk and mitigate the effects of ozone on film strength.

Description

technical field [0001] The invention belongs to the field of safety protection, relates to colloidal gloves used for hand protection, in particular to a disposable nitrile glove 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 industry, biology, etc., and are indispensable for hand protection and cross infection prevention. Protective 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] But nitrile gloves also have c...
