Abstract
The invention discloses a composite insulator umbrella skirt material, belongs to the field of umbrella skirt materials of transmission line composite insulators, and aims to solve the problem that a current umbrella skirt is insufficient in mechanical strength, short in usage time and the like. The composite insulator umbrella skirt material disclosed by the invention comprises the following components in parts by weight: 40-60 parts of methyl vinyl silicone rubber, 30-50 parts of ethylene vinyl acetate copolymer, 40-60 parts of ceramic powder, 5-12 parts of ferric trioxide, 3-10 parts of magnesium hydroxide, 3-10 parts of aluminum oxide, 3-5 parts of a vulcanizing agent, 3-10 parts of an antioxidant 1010 and 5-15 parts of monoammonium phosphate. The composite material disclosed by the invention integrates advantages of ceramics and rubber. Compared with a current rubber umbrella skirt, mechanical strength of the composite material is significantly improved, and the composite material has flame-retardant and antioxidant capacity.
Description
Technical field
The present invention relates to the full skirt material of transmission line composite insulator, particularly a kind of composite insulator umbrella skirt material be applicable on extra high voltage network.
Background technology
Insulator is one of primary member of transmitting line, and its effect is support wire, prevent electric current from going back to ground and increasing creepage distance, and its performance is for the safe and stable operation important of electrical network.Line insulator is mainly divided into composite insulator, porcelain insulator and glass insulator three class.Composite insulator with silicon rubber umbrella skirt sheath for external insulation, but adopt silastic material make full skirt, still cannot break away from the soft character of silicon rubber, run out of doors for a long time, full skirt easily damages, and then causes insulating property to reduce.
Summary of the invention
For solving the problem, the invention provides that a kind of physical strength is higher, the good composite insulator umbrella skirt material of insulating property.
Composite insulator umbrella skirt material of the present invention, comprises the component of following weight fraction: ethylene methacrylic silicon rubber 40-60 part, ethylene vinyl acetate 30-50 part, ceramics powder 40-60 part, ferric oxide 5-12 part, magnesium hydroxide 3-10 part, aluminum oxide 3-10 part, vulcanizing agent 3-5 part, 3-10 part antioxidant 1010, ammonium hydrogen phosphate 5-15 part.
Preferably, described composite insulator umbrella skirt material comprises the component of following weight part: ethylene methacrylic silicon rubber 40-50 part, alkene acetate ethylene copolymer 40-50 part, ceramics powder 40-50 part, ferric oxide 8-12 part, magnesium hydroxide 3-8 part, aluminum oxide 3-8 part, vulcanizing agent 3-5 part, 3-8 part antioxidant 1010, ammonium hydrogen phosphate 10-15 part.
Preferably, described ceramic powder particles diameter is 3 μm, SiO in ceramics powder
2content be 40-45%, Al
2o
3containing 40-45%.
Described vulcanizing agent is preferably 2,5 one dimethyl one 2,5 one bis(t-butylperoxy) hexanes.
Above-mentioned raw materials is made umbrella sheath through operations such as pulverizing, batching, mixing, anti-refining, shapings, then makes composite insulator through operations such as post vulcanization, umbrella sheath bonding, termination assembling, end part seals.
Compared with prior art, the invention has the beneficial effects as follows:
(1) matrix material of the present invention has merged the advantage of pottery and rubber, the physical strength of more existing rubber full skirt has obvious rising, tensile strength can reach 6.8MPa, and tear strength can reach 19.5kN/m, and elongation rate of tensile failure can to 160% simultaneously;
(2) the full skirt resistance of aging obtained by the present invention is good, can extend the time limit of service of full skirt, and then can reduce the use cost of full skirt;
(3) full skirt obtained by the present invention has good fire retardancy, even under case of fire, but full skirt has preferably cigarette ability.
