Description
Technical field
The present invention relates to a kind of material, be specifically related to a kind of insulating material.
Background technology
Along with the fast development of national economy, the power consumption of people sharply rises, and simultaneously power system is also at development and perfect, therefore also more and more higher to the requirement of the quality of power supply.In order to stable due to generating and the uneven voltage fluctuation caused of power consumption, ensure quality of voltage, in the transformer equipment in modern times, take load ratio bridging switch to carry out system voltage adjustment.
And the insulating material that the oil drum wall of load ratio bridging switch scribbles not only needs insulation also to need protection against the tide, anticorrosion, high temperature resistant.At present, although existing surface insulation description of materials is many on market, Performance comparision is single, purposes specific aim is very strong, can not accomplish the requirement of protection against the tide, anticorrosion, high temperature resistant and insulation, the insulation level of insulating material is inadequate, limits the work-ing life of load ratio bridging switch.
Summary of the invention
The invention provides a kind of insulating material, to solve the problem in work-ing life of the single and then restriction load ratio bridging switch of existing insulating material performance.
Following scheme is adopted for overcoming the above problems:
Scheme one: a kind of insulating material, the composition comprised and weight part are: nanometer grade silica 20-28 part, polycarbonate resin 20-28 part, aluminium hydroxide 20-40 part, , potter's clay 10-20 part, polyethylene 80-100 part, metallocene PE 3-10 part, polyoxyethylene glycol 1-5 part, silicon rubber 30-50 part, vulcanizing agent 2-5 part, thinner: 4-8 part, aerosil: 2-5 part, silica powder: 20-40 part, silicone oil: 4-8 part, polyether-ether-ketone resin 54-72 part, talcum powder 10-17 part, light calcium carbonate 13-20 part, lubricant 9-18 part, oxidation inhibitor 8-16 part, calcining mica 10-16 part.
The present invention with the addition of polyoxyethylene glycol (PEG) to ensure the water tree resistant property of material.Metallocene PE taxis is higher, be easy to form the spherocrystal comparatively disperseed, crystallization velocity is fast, grain-size is less, is added in polyvinyl resin, improves poly nucleation rate and crystal growth rate, decrease the size of crystal grain, thus substantially increasing the degree of crystallinity of material, metallocene polymers adds in body material, adds the elasticity of material.Metallocene PE (MPE), it is the novel thermoplastics of one of the twentieth century suitability for industrialized production nineties, because it is the polyethylene using metallocene (MAO) to produce for polymerizing catalyst, therefore, performance has from the PE that traditional Ziegler-Natta catalyst is polymerized different significantly.Aluminium hydroxide is as fire retardant, and flame retardant properties is good.
Polyether-ether-ketone is the superpolymer that the repeating unit containing a ketonic bond and two ehter bonds in backbone structure is formed.Polyether-ether-ketone has higher second-order transition temperature and fusing point, and its load heat-drawn wire is up to 316 degrees Celsius, and life-time service temperature is 260 degrees Celsius, and instantaneous use temperature can reach 300 degrees Celsius.Polyether-ether-ketone has self-extinguishing, even if do not add any fire retardant, can reach the 94V-0 level of UL standard, have rigidity and flexibility, particularly very outstanding to the fatigue resistance under repeated stress, can compare favourably with alloy material; There is excellent sliding properties, be suitable for the occasion of being strict with low-friction coefficient and abrasion performance purposes, be insoluble to any solvent and strong acid, highly basic, and hydrolysis, there is very high chemical stability.
Scheme two: on the basis of scheme one further, described potter's clay to be pulverized and is obtained after oversintering, sintering condition is under Oxygen Condition, potter's clay first sinters 1-2 hour under 500-600 degree Celsius, then be rapidly heated to 700-800 degree Celsius and keep 0.5-1 hour, then be rapidly heated to 1200-1300 degree Celsius and keep 2-3 hour, fast cooling is to 700-800 degree Celsius and keep 0.5-1 hour, be warming up to 1000-1100 degree Celsius and keep 1-2 hour, Temperature fall obtains potter's clay after pulverizing.
Potter's clay and calcining mica can improve intensity and the thermotolerance of material.Potter's clay after oversintering, especially after sintering at 1200-1300 degree Celsius, fast cooling is to 700-800 degree Celsius, be warming up to 1000-1100 degree Celsius again, the crystalline structure of the inside of potter's clay is expanded and random, with nanometer grade silica acting in conjunction, there is good insulating effect.
Scheme three: on the basis of scheme one further, described potter's clay and described calcining mica cross 300 mesh sieves.Fine and smooth potter's clay and calcining mica are conducive to fully reacting with other material.
