Description

Technical Field

[0001] The present invention relates to the technical field of gloves, in particular to a glove formula with anti-odor hand effect and a preparation method thereof. Background Art

[0002] At present, as people's awareness of protection continues to improve, the application field of gloves is becoming wider and wider, and they are widely used in various fields. According to their different uses, they can be divided into medical gloves, industrial gloves and household gloves. According to the materials, there are mainly PU gloves, PVC gloves, nitrile gloves, latex gloves and other gloves. Rubber gloves, as a common labor tool for people to protect their hands, play an irreplaceable role in people's daily lives. With the improvement of living standards, people have more demands for gloves. They hope that latex or nitrile latex gloves can not only play an isolation and protection role, but also put forward higher requirements for the wearing experience of gloves. In the wearing experience link, the sour smell produced by long-term wearing has been criticized by users, and the complaints and negative feedback generated by it are continuous. No organization or individual has yet to specifically study and solve this problem. Moreover, manufacturers pay more attention to solving problems such as the strength of gloves, and ignore the treatment of stinky hands when wearing. Therefore, it is very necessary to study a pair of gloves with anti-odor hand effect.

[0003] However, when ordinary rubber gloves are used to solve the problem of smelly hands, they mainly eliminate the rubber odor after latex ozonation and other complex reactions. By studying its working principle, the gloves made of dipping glue with anti-ozonation formula are formulated to achieve the effect of anti-smelly hands; the main deodorization process is currently the physical deodorization process, which is to apply a substance such as paraffin on the surface of rubber products, or to add paraffin to the rubber and spray it on the surface. A wax layer is formed on the surface of the rubber and under the surface layer, which hinders the contact between ozone and rubber and its diffusion into the rubber. It has a certain effect of reducing odor, but the disadvantage is that a large amount of spray frost is formed on the surface, making the rubber surface look dirty and old, affecting the appearance of the product; and this physical deodorization process cannot solve the decomposition of sweat, grease and rubber by bacteria and fungi from the root, and will still produce odor; in addition, its deodorization effect will continue to produce the phenomenon of smelly hands as the paraffin material is sprayed out. In the case of long-term wear, its effect is limited.

[0004] Therefore, developing a glove with bactericidal, antibacterial and antimicrobial capabilities to achieve a biological deodorizing hand effect is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0005] In view of the above problems, the present invention provides a glove formula with an anti-odor hand effect and a preparation method thereof, which solves the above problems of the prior art.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] A glove formula with an anti-odor hand effect, comprising the following raw materials in parts by mass:

[0008] 100-200 parts of pre-sulfurized latex, 6-14 parts of antioxidant, 0.5 parts of zinc pyrithione suspension, 0.1-10 parts of thickener, 0.1-10 parts of latex additive;

[0009] Wherein, the solid content of the pre-vulcanized latex liquid is 50-70%.

[0010] As a further technical solution of the present invention, the pre-vulcanized latex liquid is one of natural latex and nitrile latex.

[0011] As a further technical solution of the present invention, the latex additive is one or more of a softener, an anti-sticking agent, a stabilizer, a dispersant, a promoter, calcium fluoride, calcium chloride, zinc oxide, and titanium dioxide.

[0012] As a further technical solution of the present invention, the raw material further comprises 35-80 parts of a thermosensitizer.

[0013] As a further technical solution of the present invention, the main component of the zinc pyrithione suspension is zinc pyrithione, and the purity of the zinc pyrithione suspension is ≥95%.

[0014] As a further technical solution of the present invention, the zinc pyrithione suspension is 0.25%-0.55%.

[0015] The mechanism of action of the zinc pyrithione suspension is: zinc pyrithione acts as an ion carrier, passes through the cell membrane, transports protons into the cell, and then carries potassium ions away. Such shuttling back and forth destroys the ion gradient on both sides of the cell membrane, making it unable to transport nutrients and causing death. In this process, zinc pyrithione itself is not consumed, so it can continue to play a role, which is also the reason why zinc pyrithione has a persistent bactericidal effect. The zinc pyrithione suspension used in the present invention is particularly suitable for products such as polymer emulsions, latex liquids, and coatings, and can be used to protect water-based products such as internal and external coatings and fillers from bacterial contamination in a wet state, and has a very broad spectrum of bactericidal activity against bacteria, molds and other bacteria.

[0016] As a further technical solution of the present invention, the following raw materials are included in parts by mass:

[0017] 200 parts of pre-sulfurized natural latex, 13 parts of antioxidant, 0.5 parts of pyrithione zinc suspension, 10 parts of thickener, 60 parts of thermosensitizer, and 10 parts of latex additive;

[0018] The solid content of the pre-sulfurized natural latex liquid is 60%, and the purity of the zinc pyrithione suspension is ≥95.0%.

[0019] As a further technical solution of the present invention, the following raw materials are included in parts by mass:

[0020] 160 parts of pre-cured nitrile latex, 10 parts of antioxidant, 0.5 parts of zinc pyrithione suspension, 6 parts of thickener, and 10 parts of latex additive;

[0021] The solid content of the pre-cured nitrile latex liquid is 70%, and the solid content of the zinc pyrithione suspension liquid is 0.5%.

[0022] A method for preparing the above-mentioned glove formula with an anti-odor hand effect comprises the following steps:

[0023] Step A, ingredients: weigh the raw materials according to the formula;

[0024] Step B, stirring: adding antioxidant, pyrithione zinc suspension, thickener, latex additive to the constant temperature pre-vulcanized latex liquid ， Add or not add a thermosensitizer, mix evenly to obtain a dipping solution;

[0025] Step C, inserting the glove blank: heat the hand mold to 60-100 degrees Celsius, and insert the glove blank into the mold to make the two fit completely;

[0026] Step D, dipping: immerse the mold in 1.8%-3% methanol, stand it upright for 3-5 seconds, immerse it in dipping solution, take it out and shake it back and forth to make the glue surface smooth and flat;

[0027] Step E, pre-baking: pre-baking the gloves at a low temperature of 60-80°C for 15-25 minutes;

[0028] Step F, embossing: mechanical physical embossing, dwelling time 20-30s;

[0029] Step G, high temperature drying: drying at 100-120°C for 30-80 minutes, and demoulding after natural cooling.

[0030] The beneficial effects of the present invention are:

[0031] (1) The present invention uses the excellent bactericidal, antibacterial and antibacterial properties of zinc pyrithione suspension to prevent bacteria and fungi from decomposing components such as sweat, oil and latex on the hands, thereby solving the problem of stinky hands from the source. Even if the gloves are worn for a long time, stinky hands will not occur, achieving a biological deodorizing effect, and making the gloves have a deodorizing function.

[0032] (2) The present invention uses the bactericidal, antibacterial and antimicrobial properties of the zinc pyrithione suspension in a humid environment to make the gloves have a deodorizing effect when working in a sweaty or humid environment.

[0033] (3) The present invention uses the comprehensive properties of zinc pyrithione suspension, antioxidant, thickener, thermosensitizer and latex additive to make rubber gloves have antibacterial, antibacterial, bactericidal and deodorizing comprehensive properties through a specific formula, so that the gloves have antibacterial and deodorizing effects, and the non-attenuation of zinc pyrithione itself prolongs the antibacterial time, thereby improving the utilization rate of the gloves.

[0034] (4) The present invention has reasonable raw material dosage, low cost and simple preparation method, thus greatly reducing the industrial production cost. DETAILED DESCRIPTION
