Embodiment 1
[0035] Such as figure 1 Shown, the present invention provides a kind of novel preparation process of chlorination of nitrile gloves, and this novel preparation process of chlorination of nitrile gloves comprises the following steps:
[0036] Step 1, prepare latex solution;
[0037] Step 2, adding chlorine to prepare suspension;
[0038] Step 3, the mold is impregnated with chlorinated nitrile rubber suspension;
[0039] Step 4, molding of nitrile gloves;
[0040] Step five, vulcanization processing of nitrile gloves.
[0041] Latex solution is composed of nitrile rubber latex, active agent, heat stabilizer, antifungal agent, bridging agent, pure water medium and accelerator, calculated according to the distribution of quantity, including the following distribution of raw materials: nitrile rubber latex 70-90 parts, 3-5 parts of active agent, 2-3 parts of heat stabilizer, 0.5-1 part of antifungal agent, 1 part of bridging agent, 10-13 parts of pure water medium, 1-2 parts o...
Embodiment 2
[0043] Such as figure 1 Shown, on the basis of embodiment 1, the present invention provides a kind of technical scheme: preferably, step 2 also includes the following steps:
[0044] A1. Add chlorine gas and sodium chlorate solution to the latex solution, and pressurize. The pressure is 15Mpa, and the pressurization time is 15-20 minutes. Prepare a 65% emulsion, and use the high-pressure environment by pressurizing the mixed solution. Improve the mixing degree of each component in the mixture;
[0045]A2, add sodium hydroxide solution (25-30%) in 65% emulsion, shake and mix, can obtain chlorinated nitrile rubber suspension, utilize content to be the sodium hydroxide solution of 25-30% and 65 % of the emulsion, to ensure that the two can be close to the peak of the mixing rate to the greatest extent, and the operation of oscillation can further improve the mixing efficiency between the two, and increase the mixing completion of the chlorinated nitrile rubber suspension;
[00...
Embodiment 3
[0048] Such as figure 1 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: preferably, step 3 also includes: the outer surface of the mold is coated with a coagulant, and the cooperation of the coagulant and the mold is used to make the When the nitrile rubber suspension is attached to the mold, it can be molded as soon as possible, shortening the molding time. The mold is immersed in the chlorinated nitrile rubber suspension for 1.5-2 minutes, and the ambient temperature is kept at 130°C during immersion. After the immersion is completed Take it out for drying, step 5 also includes: the vulcanization of nitrile gloves is carried out in the way of mixed gas vulcanization, first place the nitrile gloves in room temperature vulcanization mortar for 5-8 minutes, and then place the nitrile gloves in steam Direct vulcanization, the steam temperature is 100-110 ℃, vulcanization is 5-10 minutes, it can be adjusted according t...
