Description
Technical field
The invention belongs to hot line work technical field, be specifically related to a kind of 35kV hot line work terpolymer EP rubber insulating gloves.
Background technology
Insulation glove for hot-line work is the insulating protection apparatus for the protection of hot line work person works safety, and it generally adopts natural rubber to make, and has insulating property and waterproof, acid and alkali-resistance, the anti-wet goods function of relevant voltage grade.
The thickness of usual insulating gloves is 2.3mm ~ 3.0mm, and natural rubber insulating gloves in this thickness range is lower due to withstand voltage level, cannot meet 35kV hot line work requirement.
To make natural rubber insulating gloves meet 35kV hot line work requirement, the thickness of gloves must be increased to more than 5mm, and operating personnel can be caused like this to use handiness greatly to decline, greatly affecting working efficiency.
Summary of the invention
The object of the invention is to solve the problem, a kind of 35kV hot line work terpolymer EP rubber insulating gloves with higher withstand voltage level and good insulating property is provided.
The technical scheme realizing the object of the invention is: a kind of 35kV hot line work terpolymer EP rubber insulating gloves, is made up: terpolymer EP rubber 100 parts of the component of following weight parts; Carbon black 40 ~ 70 parts; 0.1 ~ 1.0 part, sulphur; 2 ~ 8 parts, zinc oxide; Stearic acid 0.5 ~ 1.5 part; 2-mercaptobenzimidazole 0.5 ~ 1.5 part; N-cyclohexyl-2-benzothiazole sulfonamide 1.5 ~ 2.5 parts; Tetramethyl-thiuram disulfide 1.0 ~ 2.5 parts; Dicumyl peroxide 3.0 ~ 4.5 parts; Zinc methacrylate 5 ~ 10 parts.
The preferred terpolymer EP rubber of said components 100 parts; Carbon black 50 parts; 0.4 part, sulphur; 4 parts, zinc oxide; Stearic acid 0.7 part; 2-mercaptobenzimidazole 0.8 part; N-cyclohexyl-2-benzothiazole sulfonamide 1.7 parts; Tetramethyl-thiuram disulfide 1.5 parts; Dicumyl peroxide 3.5 parts; Zinc methacrylate 5 parts.
The manufacture method of this 35kV hot line work terpolymer EP rubber insulating gloves has following steps:
1. according to proportioning successively stearic acid, zinc oxide, 2-mercaptobenzimidazole, carbon black, zinc methacrylate are joined carry out in terpolymer EP rubber mixing, to be mixed when closing to an end, add N-cyclohexyl-2-benzothiazole sulfonamide, tetramethyl-thiuram disulfide, dicumyl peroxide and sulphur, obtain sizing material;
2. the sizing material mixed is placed 20h ~ 30h at ambient temperature, be then cut into the film being suitable for mould size;
3. in mould, coat releasing agent and be preheated to 150 DEG C ~ 170 DEG C, then the step film that 2. cutting obtains is put into mould, and mould is put on vulcanizer, be forced into 10MPa ~ 20MPa, heat-insulation pressure keeping sulfuration 5min ~ 15min, then takes out mould, is cooled to die sinking after envrionment temperature, final drying 20h ~ 30h, obtains terpolymer EP rubber insulating gloves.
Above-mentioned steps 2. described in be suitable for the length of the film of mould size × wide be 80mm × 80mm ~ 120mm × 120mm, weight is 80g ~ 120g.
The positively effect that the present invention has: (1) 35kV hot line work of the present invention terpolymer EP rubber insulating gloves adopts the terpolymer EP rubber integrated vulcanizing after modification reinforcement shaping, it is not breakdown that this insulating gloves can bear 50kV industrial frequency withstand voltage 1 minute, and leakage current is at below 10mA, there are higher withstand voltage level and good insulating property.(2) 35kV hot line work terpolymer EP rubber insulating gloves of the present invention is made general thickness and can be met 35kV hot line work requirement, substantially increases use handiness and the working efficiency of operating personnel.
