Description

Technical Field

[0001] The present invention relates to the technical field of safety protection products, and in particular to a cut-resistant glove for the crystalline silicon industry and a preparation method thereof. Background Art

[0002] With the improvement of safety awareness in the industrial field, cut-resistant gloves have become an important equipment to protect workers' hand safety in high-risk working environments. There are many types of cut-resistant gloves on the market, and gloves of different materials and designs have different performances.

[0003] In the crystalline silicon industry, the production of polycrystalline silicon and monocrystalline silicon is unique and complex. The polycrystalline silicon production process involves high temperature, high pressure and corrosive environment. Its cutting, grinding, processing and other operations will expose the hands of workers to the risk of cutting polycrystalline silicon particles, and the gloves must have high wear resistance and durability to cope with long-term high-intensity use. Similarly, there are many dangerous factors in the production process of monocrystalline silicon. For example, in the monocrystalline silicon slicing process, the diamond wire saw and other tools used run at high speed, and the hands are extremely susceptible to cutting injuries; factors such as chemicals and dust in the monocrystalline silicon production environment also place strict requirements on the protective performance of gloves.

[0004] Traditional gloves are difficult to fully meet the complex protection needs of polysilicon and monocrystalline silicon production environments in the crystalline silicon industry. Some existing gloves have problems such as unsatisfactory cut protection and short service life. Some gloves will also affect the sensitivity of the hands to a certain extent, which will have an adverse effect on workers' operations, which may reduce production efficiency and even increase the risk of safety accidents.

[0005] Therefore, there is an urgent need to develop a cut-resistant glove for the crystalline silicon industry that can meet the protection needs in the production environment of polycrystalline silicon and monocrystalline silicon. Summary of the invention

[0006] The object of the present invention is to provide a cut-resistant glove for the crystalline silicon industry, which can meet the protection needs in the production environment of polycrystalline silicon and monocrystalline silicon and has high wear resistance and cut resistance.

[0007] The second purpose of the present invention is to provide a method for preparing cut-resistant gloves for the crystalline silicon industry, which can conveniently and efficiently produce cut-resistant gloves for the crystalline silicon industry.

[0008] The present invention provides a cut-resistant glove for the crystalline silicon industry, comprising a glove core, wherein the finger portion and the palm portion of the glove core are coated with a wear-resistant latex layer; the glove core is formed by seamlessly weaving a mixture of two yarns, wherein the yarn comprises a first composite yarn and a second composite yarn, wherein the first composite yarn is formed by wrapping a wear-resistant yarn around the outside of a metal wire, and the second composite yarn is formed by wrapping a high-strength and low-elongation multifilament around an elastic fiber.

[0009] Preferably, the wear-resistant yarn is one of polyamide yarn and black polyester.

[0010] Preferably, the high-strength low-strength multifilament includes one or more of ultra-high molecular weight polyethylene, high-strength low-strength polyester, aramid 1414 or high-strength vinylon, and the elastic fiber is one or two of spandex, rubber yarn and polybutylene terephthalate fiber.

[0011] Preferably, the wear-resistant latex layer contains the following components in parts by mass: 50-60 parts of natural latex, 20-30 parts of nitrile rubber, 0.5-1 parts of potassium hydroxide, 5-10 parts of zinc oxide, 0.5-2 parts of sulfur powder, 5-15 parts of calcium carbide, 3-10 parts of silicon dioxide, 3-8 parts of dibutyl phthalate, 1-2 parts of stearyltrimethylammonium chloride, 1-3 parts of sodium carboxymethyl cellulose, and 0.1-0.3 parts of isothiazolinone.

[0012] The present invention also provides a method for preparing the above-mentioned cut-resistant gloves for the crystalline silicon industry, comprising the following steps:

[0013] S1. Using a coating machine to evenly coat the wear-resistant yarn on the outside of the metal wire, adjusting the yarn tension to form the first composite yarn, using a coating machine to coat the high-strength and low-stretch multifilament on the elastic fiber, adjusting the yarn tension to form the second composite yarn; preferably, the metal wire is one of stainless steel wire or copper wire;

[0014] S2. The first composite yarn and the second composite yarn are placed in a yarn rack of a knitting machine in proportion, and the glove core is knitted using a 13-needle seamless knitting process, and the cuffs of the glove core are knitted with knitted rib cuffs, and the glove core is obtained after the knitting is completed;

[0015] S3.

After the immersion is completed, slowly remove the gloves, and the excess wear-resistant latex drips naturally, and the gloves dry naturally;

[0016] S4. The dried gloves are cleaned and dried at low temperature, and then packaged to obtain the finished anti-cutting gloves for the crystalline silicon industry.

[0017] Preferably, in step S2, the ratio of the first composite yarn to the second composite yarn is (10-13):(7-9).

[0020] b. Pour the natural latex into the reactor at room temperature, start stirring, and slowly add the nitrile rubber at the same time. After stirring evenly, slowly add potassium hydroxide to adjust the pH value. Add zinc oxide while stirring and stir evenly. Stirring at room temperature can effectively prevent the temperature from being too high, causing the latex to vulcanize prematurely or other adverse reactions.

[0021] c. Add calcium carbonate, silicon dioxide, dibutyl phthalate, stearyl trimethyl ammonium chloride, sodium carboxymethyl cellulose and isothiazolinone in sequence under stirring until the mixture is evenly stirred; calcium carbonate and silicon dioxide should be added slowly to effectively avoid agglomeration; the stirring speed should be increased when calcium carbonate and silicon dioxide are added to make them evenly dispersed in the latex to avoid difficulty in mixing after the latex viscosity increases; dibutyl phthalate, stearyl trimethyl ammonium chloride and sodium carboxymethyl cellulose can increase the flexibility, antistatic property and structural strength of the latex layer;

[0022] d. Add sulfur powder in a stirring state, stir evenly, increase the temperature and pressure in the reactor, and perform vulcanization treatment. After the vulcanization is completed, vacuum degassing is performed to obtain the wear-resistant latex.

[0023] Preferably, in step b, potassium hydroxide is used to adjust the pH value to 10-13, and the stirring speed is 30-60 rpm.

[0024] Preferably, in step d, the temperature is raised to 110-140° C., the pressure is raised to 6-13 MPa, and the vulcanization treatment time is 15-25 min.

[0025] Preferably, the specific steps of washing and low-temperature drying in step S4 are: in a Class 100 clean room environment, use ultrapure water to wash the gloves 2-3 times, each time for 70-100 minutes, and then dry at 50-60° C. Preferably, 18 megohm ultrapure water is used.

[0026] Beneficial effects:

[0028] The first composite yarn in the present invention has excellent anti-cutting and wear resistance, the second composite yarn has good elasticity, and the glove core is seamlessly woven by mixing the first composite yarn and the second composite yarn, which can protect the hands of workers and improve wearing comfort.

[0029] The wear-resistant latex layer of the invention adopts multiple components for use. Firstly, the latex layer is vulcanized to form a three-dimensional network structure, thereby enhancing the strength and stability of the latex layer. Meanwhile, isothiazolinone as a bactericide can prevent the latex from mildewing and deteriorating, thereby extending the service life of the gloves. BRIEF DESCRIPTION OF THE DRAWINGS
