Description
Technical Field
The invention relates to the technical field of nitrile glove production, in particular to a glove mold alkaline washing liquid for nitrile gloves, a preparation method and a use method thereof.
Background
The production of the nitrile glove mainly comprises the following steps: dipping the hand mould with a coagulating agent, dipping the emulsion material of the nitrile glove, leaching, drying and vulcanizing, and then washing with chlorine, cleaning, drying and demolding to obtain the nitrile glove. The cleaning step is to perform acid washing and alkali washing on the hand mould on a production line to remove residual fatty acid salt type release agent (mainly calcium stearate) and a small amount of latex dirt on the hand mould, wherein the conventional alkali washing liquid is generally sodium hydroxide solution or sodium hydroxide and sodium hypochlorite mixed liquid, the effective concentration of the sodium hydroxide is generally controlled to be 3-5 wt%, like the prior art, the disposable butyronitrile glove with ozone oxidation reducing performance and the preparation method thereof use the alkali washing liquid which is sodium hydroxide solution with PH=10-11.
However, in actual production, no matter how the ratio of sodium hydroxide to sodium hypochlorite is adjusted, calcium stearate attached to the surface of the hand mould cannot be completely removed, so that a large amount of powder marks exist in the nitrile glove product, and the product quality is affected. If the effective concentration of sodium hydroxide is increased, although calcium stearate is effectively removed, the surface coating of the hand mould is damaged, so that the demoulding is difficult, normal production cannot be performed, and the rejection rate of glove production is too high.
It is therefore also desirable to develop a glove form alkali lotion for nitrile gloves.
Disclosure of Invention
The invention provides a glove mold alkali washing liquid for butyronitrile, which overcomes the defect that calcium stearate cannot be completely removed in the prior art; through the compounding of potassium hydroxide and sodium hydroxide and the synergistic effect of sodium metasilicate, sodium hexametaphosphate and sodium hypochlorite, the residues of calcium stearate and other dirt on the hand mould in the production of the nitrile glove are effectively removed, and the hand mould coating and the production rejection rate of the nitrile glove are not lost in the alkaline washing process.
The invention also aims at providing a preparation method of the glove mold alkali washing liquid.
The invention also aims to provide a using method of the glove mold alkali washing liquid.
In order to solve the technical problems, the invention adopts the following technical scheme:
the glove mold alkaline washing liquid comprises the following components in percentage by weight:
3 to 5 percent of sodium hydroxide,
2 to 3 percent of potassium hydroxide,
5 to 10 percent of sodium hypochlorite,
sodium metasilicate 0.15-0.45%,
sodium hexametaphosphate 0.03-0.1%,
the balance being water.
Sodium hydroxide and potassium hydroxide are strong bases which are completely ionized, but the metal activity of potassium element is stronger than that of sodium hydroxide, and potassium ions are more likely to form a complex which is easy to separate out with calcium stearate. Compounding sodium hydroxide with a small amount of potassium hydroxide can allow for the removal of greater amounts of calcium stearate with limited alkali concentrations.
The chemical formula of the sodium metasilicate in the invention is Na 2 SiO 3 Is an ionic compound containing sodium cations and polymeric metasilicate anions. Sodium silicate is of all formulae Na 2x SiyO 2y Sodium metasilicate, a generic term for ionic compounds of +x, is a sodium silicate, a compound having sodium cations and silicate (SiO 3 2- ) Anionic sodium silicate.
Sodium metasilicate is a low molecular crystal prepared by the hydrothermal reaction of common sodium silicate and caustic soda. Sodium metasilicate can be hydrolyzed in water to produce silicon salt, and the silicon salt is insoluble in water and suspended in a micelle structure, so that the sodium metasilicate has suspending and dispersing capabilities on particles of solid dirt and has an emulsifying effect on greasy dirt. Thus, the addition of sodium metasilicate prevents redeposition of the removed calcium stearate scale on the surface of the hand mold. Meanwhile, silicate can form precipitation with high-valence metal ions in water, and iron salt and complex calcium and magnesium ions in water can be removed.
Sodium hexametaphosphate is easy to dissolve in water and can form soluble chelate with metal ions. In the alkaline washing process of the hand mould, the sodium hexametaphosphate forms a soluble chelate by chelating, so that the residue of calcium stearate is greatly avoided.
The inventor researches and discovers that the residues of calcium stearate and other dirt on the hand mould in the production of the butyronitrile glove are effectively removed through the compounding of potassium hydroxide and sodium hydroxide and the synergistic effect of sodium metasilicate, sodium hexametaphosphate and sodium hypochlorite, and the hand mould coating is not damaged and the demoulding property is not influenced in the alkaline washing process.
The sodium metasilicate is generally classified into anhydrous sodium metasilicate, pentahydrate sodium metasilicate and nonahydrate sodium metasilicate according to the content of crystal water.
Preferably, the sodium metasilicate is sodium metasilicate pentahydrate.
The sodium metasilicate pentahydrate has strong wetting, emulsifying and saponification effects on fatty acid substances, and can remove the residue of calcium stearate more efficiently.
Preferably, the glove molding alkali lotion comprises the following components in percentage by weight:
3.5 to 4.5 percent of sodium hydroxide, 2.3 to 2.8 percent of potassium hydroxide, 6 to 9 percent of sodium hypochlorite, 0.2 to 0.4 percent of sodium metasilicate, 0.05 to 0.08 percent of sodium hexametaphosphate and the balance of water.
Preferably, the pH of the glove is 12-14.

dispersing sodium metasilicate and sodium hexametaphosphate in part of water to obtain a dispersion liquid; mixing sodium hydroxide, potassium hydroxide, dispersion liquid and the rest water to obtain a mixed liquid;
and dissolving sodium hypochlorite in the mixed solution to obtain the glove alkali washing liquid.
Preferably, the total concentration of sodium metasilicate and sodium hexametaphosphate in the dispersion is 20 to 30wt.%.
Since sodium metasilicate and sodium hexametaphosphate are powdery solids at room temperature, specifically, sodium metasilicate and sodium hexametaphosphate can be mixed and added into water, and then stirred at a speed of 1500-1800 rpm for 30-60 min to obtain a dispersion.
The sodium hydroxide can be sodium hydroxide solution, and is added after the effective concentration is calculated; or solid sodium hydroxide.
Preferably, the sodium hydroxide is added in the form of a sodium hydroxide solution having a concentration of 32 to 50wt.%.
The sodium hydroxide is added in the form of solution, so that on one hand, the temperature of the solution in the preparation process can be reduced, safety accidents caused by the use of high-concentration strong alkali in the preparation process are prevented, on the other hand, the solution is easier to keep activity, the solid is easy to deteriorate, other impurities are introduced into the alkaline washing liquid, and the hand mold is polluted.
Preferably, the sodium hypochlorite is added in the form of a sodium hypochlorite solution having a concentration of 10 to 15 wt.%.
Sodium hypochlorite is added as a lower concentration solution, which can make its mixing faster and more uniform.
The invention also provides a use method of the glove alkali washing liquid, which comprises the following steps:
and (3) at the temperature of 60-65 ℃, using the glove alkali washing liquid of the glove hand mould to wash the glove alkali.
Compared with the prior art, the invention has the beneficial effects that:

| pH | 12.5 | 12.6 | 12.5 | 12.5 | 12.6 | 12.4 |
According to the test results in Table 3, the pH value of the alkali washing liquid for the glove with the glove mould prepared by the embodiment of the invention is between 12 and 14, the alkali washing effect is excellent, the powder printing rate (powder printing rate is less than or equal to 0.24%) of the glove is greatly reduced in the production process of the glove with the nitrile, the damage to the glove with the nitrile is small, and the increase of the rejection rate of the glove is avoided.
According to the test results of examples 1 to 6, the nitrile glove prepared in example 6 was used to wash the nitrile glove with the hand pattern alkaline washing liquid, the powder print rate was relatively the lowest, and the rejection rate of the glove was also superior.
The sodium metasilicate used in example 7 was anhydrous sodium metasilicate, and the offset ratio of the nitrile glove was relatively poor compared to example 1. The sodium metasilicate is preferably sodium metasilicate pentahydrate.
According to examples 8-13, sodium hypochlorite, sodium hydroxide, sodium metasilicate and sodium hexametaphosphate are added in solution at suitable concentrations to facilitate more uniform dispersion of the components in the glove molding alkali lotion for nitrile gloves, thereby resulting in lower powder print and lower rejection rate of nitrile gloves.
Table 4 test results of comparative examples 1 to 8
Comparative examples 1 and 2 are conventional nitrile glove hand-pattern alkaline lotions, i.e., sodium hypochlorite alone or in combination with sodium hydroxide. The alkaline washing liquid prepared in comparative examples 1 and 2 is used for alkaline washing of the glove hand mould of the butyronitrile glove, calcium stearate cannot be effectively removed, and the powder printing rate of the glove is too high. And the alkaline washing liquid in the comparative example 1 is also easy to cause damage to the coating of the butyronitrile glove, so that the rejection rate of glove production is higher.
The comparative example 3 has too low potassium hydroxide content and the powder printing rate of the butyronitrile glove is higher; the high potassium hydroxide content of comparative example 4 resulted in a higher rejection rate of the nitrile glove.
In comparative examples 5 and 6, under the condition of lacking sodium metasilicate or sodium hexametaphosphate, the prepared alkaline cleaning solution can not effectively remove calcium stearate attached to the surface of the hand mould, and the glove powder printing rate is high.
Comparative example 7 uses sodium metasilicate instead of sodium metasilicate in equal amount due to no SiO 3 2- Ion, difficulty in preventing deposition of calcium stearate scale, and sodium orthosilicate is more alkaline than sodium metasilicate, resulting in excessive glove waste. In comparative example 8, sodium orthophosphate is used for replacing sodium hexametaphosphate in an equivalent way, the chelation effect on metal ions is weak, the alkali washing effect of the prepared glove alkali washing liquid is poor, and the glove powder printing rate is high.
