preparation example Construction

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

[0040] S1: Glove embryo preheating

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

[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 prev...

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 method for preparing environmentally friendly heat-sensitive nitrile protective gloves, which comprises the steps of: S1: putting the glove blank on a glove mold and heating it up; S2: dipping the glove blank heated to a predetermined temperature into the heat-sensitive nitrile latex In the pre-vulcanized rubber material; the heat-sensitive nitrile latex pre-vulcanized rubber material comprises 90-120 mass parts of nitrile pre-vulcanized rubber material, 0.5-6 mass parts stabilizer and 0.2-9 mass parts destabilizer; the destabilizer It is a substance that reduces the stability of latex and gels under the condition of heating and heating; after the preparation of the nitrile prevulcanized rubber, it is stored at room temperature, and then before dipping, the stabilizer and The destabilizing agent is added to the nitrile prevulcanized rubber compound and stirred evenly; S3: vulcanization and drying to prepare environmentally friendly heat-sensitive nitrile protective gloves. The invention does not need pre-prepared coagulant and infiltration coagulant, reduces the production process of nitrile coated gloves, shortens the production line, reduces the application of harmful substances such as methanol, and improves the production environment.

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...
