Description

A kind of modified insulating materials
Technical field
The present invention relates to field of new materials, more particularly to a kind of modified insulating materials.
Background technology
With the rapid development of the national economy, the power consumption of people steeply rises, while power system is also evolving With perfect, therefore the also more and more higher of the requirement to the quality of power supply.For the stable voltage caused by generating electricity with power consumption imbalance Fluctuation, ensure quality of voltage, load ratio bridging switch is taken to carry out system voltage regulation in the transformer equipment in modern times.And have The insulating materials scribbled on the oil drum wall of on-load shunting switch not only needs insulation to also need to protection against the tide, anti-corrosion, high temperature resistant.At present, city Although existing surface insulation description of materials is more on field, performance comparision is single, and purposes specific aim is very strong, it is impossible to accomplishes moistureproof, anti- Rotten, high temperature resistant and the requirement of insulation, the class of insulation of insulating materials is inadequate, limits the service life of load ratio bridging switch.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of good modified insulating materials of insulation effect.
In order to solve the above technical problems, the technical scheme is that：A kind of modified insulating materials, its innovative point exist In：Fraction proportioning by weight is made up of following components：
Silica 34-42 parts, polycarbonate resin 12-18 parts, plasticizer 5-8 parts, graphite 10-20 parts, aluminium hydroxide 22-47 Part, clay 13-17 parts, polyethylene 80-100 parts, iron oxide 12-14 parts, aluminum oxide 16-18 parts, metallocene PE 5-8 parts, Polyethylene glycol 6-9 parts, polyolefin 32-45 parts, chlorinated polyethylene rubber 45-65 parts, vulcanizing agent 2-5 parts, diluent 6-8 parts, gas Aerosil 3-7 parts, calcium silicates 24-26 parts, silica flour 22-35 parts, silicone oil 4-8 parts, polyether-ether-ketone resin 54-72 parts, cunning Stone flour 12-15 parts, precipitated calcium carbonate 13-20 parts, lubricant 8-12 parts, antioxidant 8-16 parts, calcining mica 10-16 parts.
Further, the clay and the calcining mica cross 300 mesh sieves.
Further, described iron oxide and aluminum oxide use powdery form material, and iron oxide and aluminum oxide Specification is 150-250 mesh.
The advantage of the invention is that：The flame-retardant insulating material of the present invention, the flame-retardant insulating material suitable for wrapping up cable, together When have it is fire-retardant and insulation function so that properties of product of the invention are more excellent, widen electrically leading for the insulating materials The application in domain.
The present invention with the addition of polyethylene glycol (PEG) to ensure the water tree resistant property of material.Metallocene PE stereoregular Property it is higher, be easily formed more scattered spherocrystal, crystallization rate is fast, and crystallite dimension is smaller, is added in polyvinyl resin, The nucleation rate and crystal growth rate of polyethylene are improved, reduces the size of crystal grain, so as to substantially increase the knot of material Brilliant degree, metallocene polymers are added in matrix material, add the elasticity of material.Metallocene PE (MPE), it is 20 generation A kind of novel thermoplastic for the industrialized production nineties of recording, because it is to be given birth to using metallocene (MAO) for polymerization catalyst The polyethylene that output is come, therefore, the PE being polymerized in performance with traditional Ziegler-Natta catalyst have significantly not Together.Aluminium hydroxide is good as fire retardant, fire resistance.
Insulaion resistance is 4.3-5.0*107 Europe after the modified insulating materials immersion of the present invention, bending strength 125- 134MPa, compressive strength 130-142MPa, parallel layers are 50-55KV to breakdown voltage, and heat resisting temperature is 190-200 degree ratio Ad eundem temperature is higher by 5.6%-11.1% as defined in GB11026.1.
