preparation example Construction

[0039] The present invention proposes a kind of preparation method of environmental protection thermosensitive nitrile protective gloves, comprises the steps:

[0040] S1: Glove embryo preheating

[0041] Put the glove blank on the glove mold, and heat the glove blank;

[0042]Wherein, the glove embryo is heated to 60-130°C.

[0043] Wherein, the glove embryo is a chemical fiber glove embryo or a cotton glove embryo; the chemical fiber glove embryo is a 13-pin glove embryo.

[0044] S2: dipping

[0045] The glove blank heated to a predetermined temperature is dipped into the heat-sensitive nitrile latex pre-vulcanized rubber, and the heat-sensitive nitrile latex pre-vulcanized rubber contains 90-120 parts by mass of nitrile pre-vulcanized rubber, 0.5-6 parts by mass Stabilizer and 0.2-9 parts by mass of destabilizing agent; said destabilizing agent is a material that makes latex less stable and gelled under the condition of heating and heating; said nitrile prevulcanized ru...

Embodiment 1

[0062] The present embodiment provides a kind of preparation method of environmental protection thermosensitive nitrile protective gloves, and its method step is as follows:

[0063] (1) Preparation of nitrile prevulcanized rubber compound

[0064] The nitrile latex with acrylonitrile content of 27% and carboxyl content of 4% is added with additives and stirred evenly, pre-vulcanized at room temperature at 25°C, and stored for 2 days. The nitrile pre-vulcanized rubber material contains : 100 parts by mass of nitrile latex, 1 part by mass of BZ (accelerator), 1.5 parts by mass of sulfur (vulcanizing agent), 2 parts by mass of zinc oxide (activator), and 1 part by mass of 2246 (antiaging agent).

[0065] (2) Heat-sensitive nitrile latex pre-vulcanized rubber

[0066] Add 6 mass parts of ammonia (33%), 2 mass parts of ammonium chloride (destabilizer), 0.6 mass parts of zinc oxide (activator) in the 100 mass parts of nitrile prevulcanized compound that pre-vulcanization is stored...

Embodiment 2

[0070] The present embodiment provides a kind of preparation method of environmental protection thermosensitive nitrile protective gloves, and its method step is as follows:

[0071] (1) Preparation of nitrile prevulcanized rubber compound

[0072] The nitrile latex with acrylonitrile content of 27% and carboxyl content of 4% is added with additives and stirred evenly, pre-vulcanized at room temperature at 25°C, and stored for 2 days. The nitrile pre-vulcanized rubber material contains : 120 parts by mass of nitrile latex, 1 part by mass of DM (accelerator), 2 parts by mass of sulfur (vulcanizing agent), 2.5 parts by mass of zinc carbonate (activator), and 1 part by mass of RD (antiaging agent).

[0073] (2) Heat-sensitive nitrile latex pre-vulcanized rubber

[0074] Add 3 mass parts of sodium hydroxide, 5 mass parts of zinc ammine ion solution (30%), 0.3 mass parts of zinc oxide (activator) in the 100 mass parts of nitrile prevulcanized compound that prevulcanization stores ...

Abstract

The invention relates to a preparation method of an environment-friendly heat-sensitive butyronitrile protective glove. The preparation method comprises the following steps: S1, sleeving a glove moldwith a glove blank, and carrying out heating; S2, soaking the glove blank having been heated to a preset temperature into a heat-sensitive butyronitrile latex pre-vulcanized rubber material which comprises, in parts by mass, 90 to 120 parts of a butyronitrile pre-vulcanized rubber material, 0.5 to 6 parts of a stabilizer and 0.2 to 9 parts of a destabilizer, wherein the destabilizer is a substancecapable of reducing the stability of latex and realizing gelling under the condition of heating; and after the butyronitrile pre-vulcanized rubber material is prepared, storing the butyronitrile pre-vulcanized rubber material at room temperature and before gum dipping, adding the stabilizer and the destabilizer into the butyronitrile pre-vulcanized rubber material and carrying out uniform stirring; and S3, performing vulcanizing and drying to obtain the environment-friendly heat-sensitive butyronitrile protective glove. According to the invention, a coagulator and an infiltration coagulator do not needed to be prepared in advance, so production procedures of the butyronitrile-coated gloves are reduced, a production line is shortened, application of harmful substances such as methanol is reduced, and a production environment is improved.

Description

technical field [0001] The invention relates to the technical field of coated gloves, in particular to a method for preparing environmentally friendly heat-sensitive nitrile protective gloves. Background technique [0002] The preparation method of rubber gloves is generally to form a layer of rubber layer after the textile glove embryo is impregnated with natural latex, synthetic latex, etc. on the surface, so that the gloves are waterproof. The preparation process of labor insurance dipped gloves is basically divided into several steps: dipping coagulant, dipping, vulcanization, etc. Among them, dipping coagulant has always been an indispensable pre-step for chemical fiber knitted glove embryos. And some cotton glove embryos will also be provided with a pre-step of impregnating a coagulant in order to be able to hang glue quickly during the dipping process. One of the purposes of impregnating the coagulant is to avoid chemical fiber knitted glove embryos and other glove e...
