Abstract
Description
Technical Field
[0001] This invention relates to the field of protective rubber gloves, specifically to a composite adhesive for chemical-resistant and antistatic gloves, chemical-resistant and antistatic gloves, and a method for preparing the same. Background Technology
[0002] Static electricity is a static charge. When an object carrying static electricity comes into contact with an object with a potential difference, the charge transfers, producing a spark discharge. In some special locations, spark discharges can easily cause fires, combustion, or even explosions, making the elimination and prevention of static electricity particularly important. In the chemical industry, many storage environments contain media that are not only alkaline, acidic, and corrosive, but also flammable and explosive. Therefore, for workers in these industries, personal protective equipment (PPE) needs to possess both chemical protection and anti-static properties.
[0003] In existing technologies, antistatic properties in gloves can be achieved by adding conductive materials such as superconducting carbon black and carbon nanotubes to latex. These conductive materials are mostly dispersed in the latex through grinding or ultrasonic homogenization. However, conductive materials are often difficult to disperse uniformly, thus failing to maximize their conductivity. In known technologies, graphene can also be added to the latex to improve the chemical resistance of gloves. However, this method requires adding large amounts of graphene to achieve antistatic properties, resulting in high costs. Therefore, it is necessary to further improve the conductivity of chemical-resistant gloves while keeping production costs low. Summary of the Invention
[0004] (a) Technical problems to be solved
[0005] In view of the above-mentioned technical problems, in order to solve the problem that the carbon nanotube conductive materials are poorly dispersed in latex in the existing technology, the conductivity cannot be fully utilized, and the finished glove has poor conductivity, the present invention provides a composite adhesive for chemical-resistant and antistatic gloves, chemical-resistant and antistatic gloves and their preparation method.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:
[0008] In a first aspect, the present invention provides a composite adhesive for chemical-resistant and antistatic gloves, wherein the raw materials for preparing the composite adhesive include carbon nanobelt dispersion and pre-vulcanized latex.
[0009] The carbon nanoribbon dispersion is prepared by cutting carbon nanotubes in a blend of oxidizing concentrated acid, hydrogen peroxide and catalyst.
[0010] Secondly, the present invention provides a chemical-resistant and antistatic glove, wherein the raw materials for preparing the chemical-resistant and antistatic glove include the above-mentioned composite adhesive.
[0011] Thirdly, the present invention also provides a method for preparing chemical-resistant and antistatic gloves, comprising the following steps:
[0012] S1. Preparation of carbon nanoribbon dispersion: Add carbon nanotubes to a mixture of oxidizing concentrated acid, hydrogen peroxide and catalyst and heat under reflux. Cut the carbon nanotubes into carbon nanoribbons to obtain a carbon nanoribbon mixture. Filter the carbon nanoribbon mixture, add water to the filter residue, stir and disperse, and then add alkaline solution to obtain an alkaline carbon nanoribbon dispersion.
[0013] S2: Add carbon nanobelt dispersion to pre-vulcanized latex to obtain composite adhesive;
[0014] S3: Immerse the impregnation model in the composite mortar, vulcanize and dry to obtain chemical-resistant and antistatic gloves.
[0015] In step S1, carbon nanotubes are cleaved into carbon nanoribbons by concentrated oxidizing acid and hydrogen peroxide under the catalysis of a catalyst. The carbon nanoribbons retain essentially the length of the carbon nanotubes, but their specific surface area is doubled. After the gloves are impregnated and dried, multiple carbon nanoribbons come into contact with each other, which facilitates the construction of a three-dimensional conductive network, thereby improving the antistatic properties of the chemical-resistant gloves. Furthermore, the cleaved edges of the carbon nanoribbons have abundant carboxyl, hydroxyl, and epoxy groups, exhibiting good hydrophilicity and allowing for direct dispersion in latex with high uniformity. This eliminates the need for grinding, homogenization, or other dispersion processes, and also eliminates the need for additional dispersing agents, thus improving dispersion uniformity and reducing production costs. Filtration and the addition of water to the filter residue, followed by the addition of alkali solution, ensure that the carbon nanoribbon dispersion is alkaline, matching the pH of the latex.
[0016] In step S1, the oxidizing concentrated acid and hydrogen peroxide are first mixed evenly, and then the catalyst and carbon nanotubes are added in sequence, and the mixture is heated under reflux to avoid material loss due to volatilization during the heating process.
[0017] In the preparation method of the chemical-resistant and antistatic gloves as described above, preferably, in step S1, the carbon nanotubes have a diameter of 5-18 nm, a length of 0.7-30 μm, and 1-5 layers; the carbon nanoribbons obtained after cutting the carbon nanotubes have a width of 15-50 nm, a length of 0.5-20 μm, and 1-5 layers.
[0018] After being cut, carbon nanotubes change from tubular to expanded carbon nanoribbons. Therefore, the width of carbon nanoribbons increases compared to carbon nanotubes. However, cutting does not cause all carbon nanotubes to be transformed into carbon nanoribbons at once. Some carbon nanotubes are cut into smaller carbon nanotubes and then regenerated into carbon nanoribbons. Therefore, the length of carbon nanoribbons decreases compared to carbon nanotubes.
[0019] In this invention, the number of carbon nanotube layers can be 1-5. After cutting, the number of carbon nanotube layers may decrease or remain unchanged. Therefore, the number of carbon nanoribbon layers is also 1-5.
[0020] In the preparation method of the chemical-resistant and antistatic gloves described above, preferably, the carbon nanotubes have a diameter of 11-16 nm, a length of 0.7-30 μm, and 1-5 layers.
[0021] In this invention, the diameter of the carbon nanotubes affects the chemical and antistatic properties of the gloves. When the diameter of the carbon nanotubes is 5-18 nm, the resulting carbon nanoribbons after cutting can significantly increase the antistatic and chemical protective properties of the gloves. Preferably, the diameter of the carbon nanotubes is 11-16 nm.
[0022] In the preparation method of the chemical-resistant and antistatic gloves as described above, preferably, in step S1, the oxidizing concentrated acid is concentrated sulfuric acid or concentrated nitric acid, the mass fraction of concentrated sulfuric acid is 93-98%, preferably 96%, the mass fraction of concentrated nitric acid is ≥65%, the mass fraction of hydrogen peroxide is 20-40%, preferably 30%, and the catalyst is one or more of Fe, Co, Ag, Ni, Fe compounds, Co compounds, Ag compounds, and Ni compounds, and the mass ratio of the catalyst to carbon nanotubes is 1:5-1:10.
[0023] The proportion of catalyst added affects the cutting time of carbon nanotubes. When the mass ratio of catalyst to carbon nanotubes is 1:5-1:10, carbon nanoribbons can be obtained within 5-7 hours. If the amount of catalyst added is too small, the cutting time will be prolonged.
[0024] In the preparation method of the chemical-resistant and antistatic gloves as described above, preferably, in step S1, the volume percentage of concentrated sulfuric acid in the blend of concentrated sulfuric acid and hydrogen peroxide is 65-80%, and the volume percentage of hydrogen peroxide is 20-35%.
[0025] In the method for preparing chemical-resistant and antistatic gloves as described above, preferably, in step S1, the heating temperature is 80-90℃ and the heating reflux time is 5-7h;
[0026] The alkaline solution is a sodium hydroxide solution or a potassium hydroxide solution, and the concentration of the alkaline solution is 0.05-3 mol / L; the pH of the carbon nanoribbon dispersion is 8-12.
[0027] Latex itself is alkaline. In order to match the pH of the carbon nanobelt dispersion, the pH needs to be adjusted to 8-12.
[0028] In the preparation method of the chemical-resistant and antistatic gloves as described above, preferably, in step S2, the pre-vulcanized latex used is pre-vulcanized nitrile rubber latex, pre-vulcanized chloroprene rubber latex, pre-vulcanized styrene-butadiene rubber latex, or pre-vulcanized natural rubber latex.
[0029] In the preparation method of the chemical-resistant and antistatic gloves described above, preferably, in step S2, after adding the carbon nanoribbon dispersion to the pre-vulcanized latex, a thickener is added to obtain a composite adhesive with a viscosity of 500-3000 mPa•s; the thickener is one or more of cellulose, CMC (carboxymethyl cellulose), HPMC (hydroxypropyl methyl cellulose), HEMC (hydroxyethyl methyl cellulose), casein, and sodium polyacrylate.
[0030] In step S2, the composite adhesive contains 100 parts of pre-vulcanized latex and 0.01-1.00 parts of carbon nanoribbons. In this invention, the 100 parts of pre-vulcanized latex and the 0.01-1.00 parts of carbon nanoribbons are all by dry weight.
[0031] (III) Beneficial Effects
[0032] The chemical-resistant and antistatic gloves of this invention use a composite adhesive formed from a carbon nanoribbon dispersion and a pre-vulcanized latex as raw materials. The carbon nanoribbon dispersion contains carbon nanoribbons, which are prepared by cutting carbon nanotubes in a blend of concentrated sulfuric acid, hydrogen peroxide, and a catalyst. The cut carbon nanoribbons retain essentially the length of the carbon nanotubes, but their specific surface area is doubled compared to carbon nanotubes. The contact between multiple carbon nanoribbons facilitates the construction of a three-dimensional conductive network, thereby improving the antistatic properties of the chemical-resistant gloves.
[0033] The cut edges of carbon nanoribbons have abundant carboxyl, hydroxyl, and epoxy groups, which have good hydrophilicity and can be directly dispersed in latex with high dispersion uniformity. No grinding, homogenization or other dispersion processes are required, and no additional dispersing agents are needed, which improves the uniformity of dispersion and reduces production costs.
[0034] The vertical resistance of the chemical-resistant and antistatic gloves of this invention can reach 10. 7 Ω and below, much less than 10 8 Ω provides good antistatic properties. Furthermore, the gloves of this invention also exhibit good chemical resistance, offering good protection against chemicals such as sulfuric acid, sodium hydroxide, toluene, and methanol.
