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] Adopt the preparation method comprising the following steps to prepare disposable nitrile gloves of the present invention:

[0075] Step 1) preparation generates the dipping nitrile latex of inner film 2-1: take by weight 100 parts of nitrile rubber emulsion respectively, 0.82 part of potassium hydroxide, 0.0079 part of Tween 80 (surfactant), positive 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, and stir clockwise for 71 Minutes, stirring speed is 89 rev / min, grind 4 times with colloid mill; The pH value of the obtained latex is 7.09~7.61;

[0076] Step 2) prepare and generate the dipping nitrile latex of middle layer adhesive film 2-2: take by weight 100 parts of nitrile rubber emulsion respectively, 1.08 parts of potassium hydroxide, 0.0128 part of Tween 80 (surfactant), positive heptyl 0.093 parts of alc...

Embodiment 2

[0094] The hand model used in this embodiment is a hand model that can produce sweat and its water vapor discharge structure 2-1-2, and its basic structure is as follows Figure 8 As shown, the surface of the hand mold has strip-shaped depressions 1-3, and the cross-section of the strip-shaped depressions 1-3 is a semi-ellipse. The major axis of the semi-ellipse is 0.62 mm, and the minor axis 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 as shown, Figure 9 The right picture of is the front view of the hand model capable of producing sweat and its water vapor discharge structure 2-1-2, and the left picture is the rear view. Each finger is provided with 6 strip-shaped depressions 1-3, and a total of 30 strip-shaped depressions 1-3 are provided on the surface of the hand mold, and each strip-shaped depression 1-3 extends to the wrist of the hand mold. The strip-shaped depr...

Abstract

The invention discloses a disposable butyronitrile glove, which is provided with an acid-base indicating strip and an organic solvent indicating strip, and consists 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 film is mainly composed of nitrile rubber and related auxiliary materials thereof. Polylysine and dopa are added into the inner-layer adhesive film, nano iron powder is added into the middle-layer adhesive film, and nano manganese dioxide is added into the outer-layer adhesive film. The butyronitrile glove is further provided with a sweat and water vapor discharging structure. The invention further discloses a preparation method of the disposable butyronitrile glove. The disposable butyronitrile glove prepared by the preparation method disclosed by the invention can indicate whether the gloves are contaminated by pollutants such as acid, alkali, organicsolvents and the like or not, reduce or avoid accumulation of hand sweat and water vapor thereof, relieve hand itching in a wearing process, prompt damage risks and slow down the influence of ozone onthe strength of an adhesive film.

Description

technical field [0001] The invention belongs to the field of safety protection and relates to rubber 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 hygiene, beauty salons, food processing, chemical industry, biology, etc., to protect hands and prevent cross-infection. protective equipment. 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. Because there is no pol...
