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）

[0015] The 35kV live working EPDM insulating gloves of the present embodiment are made of the following components by weight:

[0016] EPDM rubber 1000g; carbon black 500g; sulfur 4g; zinc oxide 40g; stearic acid 7g; 2-mercaptobenzimidazole 8g; N-cyclohexyl-2-benzothiazole sulfenamide 17g; Thiuram methyl 15g; Dicumyl peroxide 35g; Zinc methacrylate 50g.

[0017] The manufacturing process of the EPDM insulating gloves for above-mentioned 35kV live work has the following steps:

[0018] 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.

[0019] At the end of mixing, add N-cyclohexyl-2-benzothiazole sulfenamide, tet...

Embodiment 2～ Embodiment 3）

[0024] Each embodiment is basically the same as Embodiment 1, and the differences are shown in Table 1.

Abstract

The invention discloses a pair of ethylene-propylene-diene monomer rubber insulating gloves for 35kV live line work, and each glove is prepared by using the components in parts by weight as follows: 100 parts of ethylene-propylene-diene monomer rubber, 40-70 parts of carbon black, 0.1-1.0 part of sulfur, 2-8 parts of zinc oxide, 0.5-1.5 parts of stearic acid, 0.5-1.5 parts of 2-mercapto benzimidazole, 1.5-2.5 parts of N-cyclohexyl-2-benzothiazole sulfenamide, 1.0-2.5 parts of tetramethyl thiuram disulfide, 3.0-4.5 parts of dicumyl peroxide and 5-10 parts of zinc methacrylate. The pair of ethylene-propylene-diene monomer insulating gloves for the 35kV live line work can withstand 50kV power frequency withstand voltage and cannot be broken down within 1min, a leakage current is below 10 mA, and the pair of gloves has a higher voltage withstand level and better insulating properties, can meet requirements of the 35kV live line work, and does not influence the use flexibility and the working efficiency of an operator.

Description

technical field [0001] The invention belongs to the technical field of live work, and in particular relates to EPDM insulating gloves for 35kV live work. 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.
