Abstract
The invention provides a shielding coating of a low-frequency transformer. A shielding housing is also arranged outside the transformer, main components of the housing can be nonmetal materials or low-price metal materials; shielding coatings are coated on the inner surface and the outer surface of the housing; main components of the coating are ferromagnetic oxide powder, wherein a titanate coupling agent is also added into the ferromagnetic oxide powder, nonionic polymer glucan and anionic polymer sodium alginate are selected as a surfactant and a diluting agent of the ferromagnetic oxide powder, thermoplastic acrylic resin is selected as a bonding adhesive, and the prepared micro powder is coated on the inner surface and the outer surface of the shielding housing. The shielding coating has obvious advantages that the low-frequency transformer is provided with the shielding protective housing, and the shielding coatings made of magnetic materials are coated on the inner surface and the outer surface of the housing, thereby not only playing a role of protection, but also saving the cost.
Description
Technical field
The present invention relates to a kind of transformer coating, especially a kind of shielding coating of low-frequency transformer.
Background technology
Along with the fast development of technology such as electronics, communication, electromagnetic radiation has become a kind of new pollutant sources, and the World Health Organization classifies electromagnetic radiation pollution as third place in the world big public hazards.A series of problems such as the electromagnetic radiation pollution meeting causes that electromagnetic interference, electromagnetic environment pollution and electromagnetic information are divulged a secret.The research major part in past concentrates on the radiation hazradial bundle of electric field.Find that by a large amount of investigation the harm of low frequency magnetic field is particularly serious now.On the one hand, the magnetic interference of low frequency magnetic field generation is the key factor that influences other electronic electric equipment operate as normal.Near the image of the computer for example, the low frequency magnetic field that engine produced can make and reading and communication equipment produce distortion.On the other hand, low frequency magnetic field can make central nervous system disorder, the cardiovascular system imbalance of human body, and increases the incidence of disease of leukaemia, brain tumor, breast cancer.Therefore, low frequency magnetic field can seriously jeopardize national politics, military affairs and social safety, and the radiation of low frequency magnetic field is employed prevention and control measures seems very necessary.
The method that reduces the low frequency magnetic field radiation has a lot, and except that reasonable line arrangement structurally, rationally settle the component, it also is a kind of effective ways that the employing magnetic shielding material carries out magnetic screen.For example, set up magnetic shield room, electric power, electronic equipment casing are carried out magnetic screen, holding wire and power line are shielded, reach the purpose that prevents that external magnetic field from disturbing equipment, device with magnetic shielding material with magnetic shielding material.Therefore, from the material angle, research and develop particularly necessity of new low-frequency electromagnetic wave magnetic shielding material.Traditional low frequency magnetic shielding material adopts homogenous materials such as sheet metal, thin slice, strip more, makes the low frequency magnetic shielding material as iron commonly used, silicon steel sheet, stainless steel, permalloy etc.Material often is machined into thin plate, thin slice or strip, and this not only can reduce the magnetic shield performance of material, and makes energy consumption increase, cost up, cost performance reduce, use inconvenient.
Summary of the invention
At the problems referred to above, the invention provides a kind of shielding coating of low-frequency transformer.
A kind of shielding coating of low-frequency transformer, it is characterized in that outside transformer, also being provided with a screening can, the main component of shell itself can also can be the cheap metal material for nonmetallic materials, surface and outer surface all scribble curtain coating within it, the main component of coating is a ferromagnetic oxide powder, wherein also add titanate coupling agent, select nonionic macromolecule glucan and anionic polymeric hydantoin mosanom surface modifier as iron powder, diluent and thermoplastic acrylic resin are as adhesive, and the micro mist coating that is made into is coated on the surfaces externally and internally of screening can.
Remarkable result of the present invention is to be provided with the shielding protection shell on low-frequency transformer; in order to save cost, can adopt cheap material to make screening can, and the curtain coating that some magnetic materials of coating are made on its shell surfaces externally and internally; not only can play a protective role, also save cost.
Embodiment
Below the present invention will be further described: outside transformer, also be provided with a screening can, the main component of shell itself can also can be the cheap metal material for nonmetallic materials, surface and outer surface all scribble curtain coating within it, the main component of coating is a ferromagnetic oxide powder, wherein also add titanate coupling agent, select nonionic macromolecule glucan and anionic polymeric hydantoin mosanom surface modifier as iron powder, diluent and thermoplastic acrylic resin are as adhesive, and the micro mist coating that is made into is coated on the surfaces externally and internally of screening can.
Apply the present invention in the shielding protection of low-frequency transformer; on low-frequency transformer, be provided with the shielding protection shell; in order to save cost; can adopt cheap material to make screening can; and the curtain coating that some magnetic materials of coating are made on its shell surfaces externally and internally; not only can play a protective role, also save about 40% cost.
