Description

Anticreep and anti-electromagnetic radiation electro-thermal mulching film and preparation method thereof

technical field:

the present invention relates to warming installation in a kind of building, be specifically related to a kind of anticreep and anti-electromagnetic radiation electro-thermal mulching film and preparation method thereof.

background technology:

indoor environment heating is at present mainly to adopt water, gas heating and electric power heating two large classes, and the heating of water, gas need to be laid the main equipment such as heat supplying pipeline and heating boiler in indoor and outdoor, one-time investment is larger, need to safeguard throughout the year, and temperature is difficult for controlling separately, need extra installation of heat radiator, by taking indoor limited usable floor area, also for interior decoration causes difficulty.Electricity heating is obviously better than water, gas pipe network heating, there is small investment, safeguard simple, the advantages such as temperature control is easy, but electricity is warmed oneself except various movably electric heating devices at present, and its non-moving electric heating device is to take diaphragm structure, Electric radiant Heating Film is fixed on wall and ceiling, this heating also brings inconvenience to decoration, and ceiling heating makes indoor upper temp higher, does not feel like oneself.But meanwhile, electricity heating has also brought a lot of problems, and the problem that electrical heating mulch film exists mainly contains: (1) exists the current leakage causing due to distribution capacity, lay area when scene and easily cause earth leakage protective device action when larger; (2) easily cause in use electric field radiation.And Electric radiant Heating Film in the market does not all have enough safeguard procedures to overcome current leakage and electric field radiation, make electric geothermal heating have hidden danger, when serious, even can affect the healthy and life security of people.

summary of the invention:

the object of the invention is provides a kind of anticreep and anti-electromagnetic radiation electro-thermal mulching film and preparation method thereof for the problem of above-mentioned existence, has good heat dissipation effect, has good leakproof electrical, and comfort level is high, is convenient to the electric heating ground film that lay on ground.

above-mentioned object realizes by following technical scheme:

anticreep and anti-electromagnetic radiation electro-thermal mulching film, its composition comprises: one group of electrothermal film unit, described electrothermal film unit is bonded by two-layer or two-layer above mylar, on adhesive surface, edge, both sides has the conductive electrode of starching printing by silver, the conductive electrode of described both sides connects respectively wire, between the conductive electrode of described both sides, connect equally distributed ink bus, described both sides, mylar outside have respectively conductive aluminum foil, described conductive aluminum foil connects zero wire electrode, described conductive aluminum foil outside has PE big envelope, described PE big envelope outside has PVC protection big envelope, described wire connects power supply, the power density of described electrothermal film is every square metre of 160-320w, the main flow ripple of the far infrared producing is between 8-14 micron.

a kind of manufacture method of anticreep and anti-electromagnetic radiation electro-thermal mulching film: the method comprises the steps:

(1) be that ink bus is printed on polyester film by printing process by heater, again by printing process by contact both sides conductive electrode by silver starch be printed on polyester film both sides form basement membrane be electrothermal film unit main body, the power density of described electrothermal film is every square metre of 160-320w, between the young 8-14 micron of main flow ripple of the far infrared producing;

(2) by compound working procedure on described basement membrane compound one deck with polyester film and the wire of hot-setting adhesive;

(3) by compound working procedure, the conductive aluminum foil with hot-setting adhesive is compound in to the outside of polyester film, and zero wire electrode is connected on conductive aluminum foil counterpoise grounding;

(4) encapsulate PE big envelope and PVC protection big envelope by packaging process.

beneficial effect:

1, energy-conserving and environment-protective: electric heating ground film closer to human body, makes the heat that Electric radiant Heating Film is sent obtain fully effectively utilizing with respect to ceiling film and wall film; Nearly 100% as its electric conversion efficiency of low-temp radiating electrothermal membrane, to also have autonomous temperature adjustment automatically to control function, power consumption easily measures, and saves and returns, and user easily sets up the consciousness of behavior energy saving, has avoided unnecessary waste.

electric radiant Heating Film is the heating facility that directly clean energy resource electric power is converted to heat energy, fully demonstrates the environmental-protecting performance of Electric radiant Heating Film.

2, comfort health-care: electric heating ground film heating meets the needs of human body to heating, warm of foot is cool, and be the heat supply of large area low-temp radiating, make the lower and uniform temperature fields of surface temperature, compared with the heating system of traditional convection type, indoor mobile without thermal current, can reduce floating dust and air dry, make people feel comfortable.In addition, the main flow ripple of the Far infra-red hot ray that Electric radiant Heating Film produces is between 8-14 micron, in the majority with 9.5 microns of flux, and this is considered to people and the most useful wave band of plant growth, also be called visually " light of life ", so its health-care effect is also apparent.

3, the scope of application: Electric radiant Heating Film working power both can also be suitable for dc source with handing over, and supply voltage is from 90-300V, and power density is from every square metre of 160-320W, and these are all for the application of Electric radiant Heating Film provides a broad scope.

4, safe and reliable: foreign applications Electric radiant Heating Film should have history existing three, 40 years, but also still limits to and be installed on canopy face or metope so far, not yet have that to be installed under cement flooring be that electric heating ground film product comes out.Electric heating ground film heating is that Electric radiant Heating Film is embedded in to subsurface, realizes the function of ground radiation heating, and its key problem in technology is the technology such as waterproof, insulation, anticreep, anti-electromagnetic radiation.Because ground all can be moist in construction and use procedure problem, good waterproof and high-strength insulation are necessary; They are two years old, be embedded in subsurface because be, can be because architectural characteristic produces weak capacitive between Electric radiant Heating Film and ground, under alternating current, will generation current, this electric current is from the Electric radiant Heating Film ground of leading, form leakage current, certainly, when enough large, can make the earth leakage protective device of electric power system move, and cannot normally work; Its three, owing to being the more close human body of its heating of electric heating ground film heating, prevent that electromagnetic field radiation from also must consider in it.

the electric heating ground film of this patent adopts the dual waterproof of overall double insulation, and the measures such as earth-fault protection, electric leakage recovery and anti-electromagnetic radiation are installed.Electric heating ground film heating system adopts the dual waterproof of double insulation and has the multinomial designs such as leakage protection, electromagnetic shielding.It reaches GB II electric appliances level in anti-electric shock grade.Electromagnetic protection reaches GB primary standard, all crowds (comprising baby, pregnant woman and the old,weak,sick and disabled person) that hang up one's hat, work and live under this environment, and its health is unaffected.Its classification of waterproof exceedes GB IPX7; More than tide state insulaion resistance can reach 100M Ω.

5, easy for installation: electric heating ground film, integrated height, only need make at the scene simple plug and connect.This has not only simplified construction technology, and to workmen, also without special requirement, this will greatly improve efficiency of construction and reduce personnel cost.
