Description
Technical field
The invention belongs to insulating materials technical field more particularly to a kind of lamp package insulating materials.
Background technology
Insulating materials is the material for the current-carrying part of different potentials to be isolated, and conductivity is about in 10-100 west/rice
Below.By standard GB/T/T2900.5-2013 regulations, the definition of insulating materials is：" it is used for that device is made electrically to insulate
Material ", that is, can prevent electric current by material.Such as in motor, the insulating materials around conductor is isolated by turn-to-turn
And keep apart with the stator core of ground connection, to ensure the safe operation of motor.
There are many insulating materials type, can divide gas, liquid, solid three categories.Common gas insulating material has air, nitrogen
Gas, sulfur hexafluoride etc..Liquid insulating material mainly has mineral insulating oil, synthetic insulating oil（Silicone oil, detergent alkylate, poly- isobutyl
Alkene, isopropyl biphenyl, diarylethane etc.）Two classes.Solid insulating material can be divided to organic and inorganic two class.Organic solid insulation material
Material include insulated paint, insulating cement, insulating paper, non-conductive fibre product, plastics, rubber, varnished cloth paint pipe and insulation impregnating fibre,
Electrician's film, composite article and adhesive tape, electrician's laminated product etc..Inoganic solids insulating materials mainly has mica, glass, pottery
Porcelain and its product.In contrast, solid insulating material is numerous in variety, also mostly important.
Requirement of the different electrical equipments to insulating material properties emphasizes particularly on different fields.High pressure electrical device such as high-voltage motor, height
The insulating materials of voltage cable etc. requires have high breakdown strength and low dielectric loss.Low-voltage electrical apparatus is then with mechanical strength, disconnected
Elongation, temperature classification etc. are split as major requirement.
The macro property of insulating materials such as electrical property, hot property, mechanical property, chemical-resistant resistance, weatherability variation, corrosion resistant
The performances and its chemical composition, molecular structure etc. such as erosion have substantial connection.Inoganic solids insulating materials is mainly by silicon, boron and more
Kind metal oxide composition based on ionic structure, is mainly characterized in that heat resistance height, and operating temperature is generally higher than 180 DEG C, surely
It is qualitative good, resistance to weathering, chemical resistance and the ageing properties under electric field action are good for a long time；But brittleness is high, resistance to punching
Hit intensity is low, high pressure and tensile strength is low；Craftsmanship is poor.Organic material is generally polymer, and heat resistance is usually less than nothing
Machine material.Material its heat resistance containing the elements such as aromatic ring, heterocycle and silicon, titanium, fluorine is then higher than general line chain high molecular material.
An important factor for influencing insulating materials dielectric properties is the power of molecular polarity and the content of polar compound.Polarity material
The dielectric constant of material, dielectric loss are above non-polar material, and easily adsorbing contaminant ion increases conductance and reduces its Jie
Electrical property.Therefore it is noted that cleaning, prevents from polluting in insulating materials manufacturing process.Capacitor electricity consumption medium requirements have high dielectric
Constant is to improve its ratio characteristic.
Artificial synthesized insulating materials is rapidly developed since the thirties, mainly there is acetal resin, neoprene, polychlorostyrene
Ethylene, butadiene-styrene rubber, polyamide, melamine, polyethylene and it has excellent performance referred to as polytetrafluoroethylene (PTFE) of King etc..These
The appearance of synthetic material has played significant role to electrotechniical development.If acetal enameled wire is for motor, make its operating temperature
It is improved with reliability, and the volume and weight of motor substantially reduces.Glass fibre and its braid over braid succeed in developing and organosilicon
The synthesis of resin increases H grades of this temperature classifications for motor insulation again.And with the popularity of humanized concept and novel harmony
The composition of society, design that a kind of intensity is high, hardness is high, elongation at break is high and the lamp package insulating materials of good insulating and its
Preparation method is very important.
