Problems solved by technology

[0003] Usually the thickness of insulating gloves is 2.3mm ~ 3.0mm, and natural rubber insulating gloves within this thickness range cannot meet the requirements of 35kV live work due to their low withstand voltage level.
[0004] To make natural rubber insulating gloves meet the requirements of 35kV live work, the thickness of the gloves must be increased to more than 5mm, which will greatly reduce the flexibility of the operators and greatly affect the work efficiency

Embodiment 1）

[0011] The EPDM insulating gloves of the present embodiment are made of the following components in parts by weight:

[0012] EPDM rubber 1000g; carbon black 600g; sulfur 7g; zinc oxide 60g; stearic acid 10g; 2-mercaptobenzimidazole 12g; N-cyclohexyl-2-benzothiazole sulfenamide 20g; 20g of thiuram; 38g of dicumyl peroxide; 80g of zinc methacrylate.

[0013] The manufacturing process of the above-mentioned EPDM insulating gloves has the following steps:

[0014] ① Add stearic acid, zinc oxide, 2-mercaptobenzimidazole, carbon black, and zinc methacrylate weighed according to the proportion to the EPDM rubber compound for mixing. During the mixing process, it is necessary to pass Mechanical mixing, so that the above components are completely and evenly dispersed in the EPDM rubber compound, avoiding the decline in the mechanical properties of the rubber due to uneven mixing.

[0015] At the end of mixing, add N-cyclohexyl-2-benzothiazole sulfenamide, tetramethylthiuram disulfid...

Embodiment 2～ Embodiment 3）

[0020] Each embodiment is basically the same as Embodiment 1, and the differences are shown in Table 1.

[0021]

[0022]

[0023] It can be seen from Table 2 that the EPDM insulating gloves prepared by the present invention have a higher withstand voltage level, better insulation properties and mechanical properties, and can meet the requirements of 35kV live work.

Abstract

The invention discloses a manufacturing method of an ethylene-propylene-diene monomer (EPDM) rubber insulating glove. The manufacturing method comprises the steps of adding stearic acid, zinc oxide, 2-mercapto benzimidazole, carbon black and zinc methacrylate into the EPDM rubber and mixing; when mixing is going to be finished, adding N-cyclohexyl-2-benzothiazole sulfonamide, tetramethyl thiuram disulfide, dicumyl peroxide and sulfur to obtain a rubber material; placing the mixed rubber material and cutting into a rubber sheet; placing the rubber sheet into a die, placing the die on a vulcanizing machine, performing vulcanization, cooling and drying to obtain the EPDM rubber insulating glove. The EPDM rubber insulating glove manufactured by the method can not be broken down after bearing 50kV power frequency withstand voltage for one minute, and the leaked current is below 10 mA; the EPDM rubber insulating glove has a relatively high voltage-resistant level and a better insulating property, can meet the 35kV live working requirement, and does not influence the use flexibility and work efficiency of operators.

Description

technical field [0001] The invention belongs to the technical field of live work, and in particular relates to a method for manufacturing EPDM insulating gloves. Background technique [0002] Insulating gloves for live work are insulating and protective equipment used to protect the safety of live workers. They are generally made of natural rubber and have the insulation performance of the corresponding voltage level and the functions of waterproof, acid and alkali resistance, and oil resistance. [0003] Usually the thickness of insulating gloves is 2.3mm ~ 3.0mm, and natural rubber insulating gloves within this thickness range cannot meet the requirements of 35kV live work due to their low withstand voltage level. [0004] To make natural rubber insulating gloves meet the requirements of 35kV live work, the thickness of the gloves must be increased to more than 5mm, which will greatly reduce the flexibility of the operators and greatly affect the work efficiency.
