Abstract

The subject of the invention relates to a novel device of paint being applied in three layers each of which has very precise properties, and the final result of which is to make it possible to produce with a brush and without heat, on any type of surface, a radiating electrical panel capable of replacing any heating system. The first layer applied has the feature of being insulating and contains particles which are highly emissive in the infrared, which gives it a radiant (radiating) power when it is heated. The second layer applied has the feature of being semi-conductive and of heating up when an electric current is passed through it. The third layer applied has the feature of being insulating as well, and of being very emissive in the infrared (by doping with emissive particles), and of being able to receive a paint dye intended to turn it into a decorative element. Two conductive leads which can also be applied to the brush supply the "thermal paint". The supply voltage can vary (220 V, 110 V, 24 V) as it is possible to modify, during application, the resistance of the "thermal paint" and therefore the power emitted per square metre.

Description

 (DESCRIPTION OF THE INVENTION) It is proven that the heating of a room at low temperature on very large exchange surfaces consumes less energy than traditional central heating systems which, starting from a specific area overheated, use local air as a thermal vehicle.

Some manufacturers have tried to make electrical heating installations in which the exchange surfaces were oversized and operated at low temperature (around 30 "C). This amounted to installing a giant surface of radiators, which made the installation complicated, expensive, and the integration of the radiators in the decoration was problematic.

Other manufacturers then produced RADIANTS heating devices using glass fabric impregnated with a semiconductor electric product, this fabric was enclosed in an insulating plastic film. This type of radiant heating on insulated glass fabric needs to be nailed to wooden rafters, on the ceiling, and therefore requires a relatively complex installation since it is still necessary to cover the glass fabric with "plasterboard" or other panels. materials. In addition, the resistivity of the glass fabric is determined in the factory, the power emitted per M2. is therefore immutable and cannot be modified by the installer when it is not sufficient to heat a poorly insulated room, for example (workshop, country house, etc.).

The product which is the subject of the invention below is therefore completely new, since for the first time it becomes possible to produce on any support (preferably non-metallic) a real electric radiant panel, by simple application with a brush at the same as an ordinary painting.

In addition it becomes possible by modifying the width of the application made on a support, to obtain exactly the desired resistance, that is to say the power emitted per M2. suitable for the room to be heated.

This product called "TERMOLAQUE" comes in the form of a varnish consisting of two main components
The first 1. component is constituted by a binder having a high resistance to temperature, a high electrical insulating power. This first binder is "doped" by the inclusion of highly emissive particles in the far infrared (short wavelength). So that under the effect of heat the radiant power of this first component is very high.

 The second 2. component is constituted by a binder which can be semiconductor or insulator, with high resistance to temperature, "doped" by inclusions of semiconductor particles of electricity whose titration is adjusted according to the resistivity desired.

The "THERMOLAQUE" therefore consists of a complex of the "Sandwich" type formed by three layers using the two components described above in the single appended figure, given by way of nonlimiting example, we see
The superposition of these three layers once the reticle coatings.

Component n "l:
Applied directly to the support (walls, ceilings) this component electrically insulates the support and will have the particularity, when heated, to emit practically all of the heat absorbed by infrared radiation.

Component # 2
Applied on component no. 1 when it is dust-free, this component two has the property of heating up as desired (the power released by M2 can be adjusted on application by reducing or increasing the width of the painted surface) under the effect of the passage of an electric current.

Component # 3
Almost identical to component no. 1, it is applied over component no. 2, when the latter is dust-free. The base binder is also "doped" with highly emissive particles in the infrared so that the painted surface radiates as much as possible towards the room or the people to be heated.The binder has been modified to allow it to receive a paint dye (choice) and use it as a decorative coating.

 It is also possible to line the "THERMOLAQUE" over or to apply a layer of plaster if applied to the ceiling 5.

 It goes without saying that once applied the "THERMOLAQUE" must be supplied at its ends by two electrical cords 4 delivered by the manufacturer. The supply voltage can vary (220 V, 110 V, 24 V) since the resistivity of the "THERMOLAQUE" can be adjusted according to the power desired by M2.

It is therefore the combination of several layers of air-curable plasters applicable with a brush on any support, the "sandwich" produced combining emissive and radiant properties as well as heating properties with the passage of an electric current, thanks the inclusion in the binders of emissive and semiconductor particles which characterizes the novelty of the invention.

However, the superposition of the layers can be changed and a layer can even be removed without this changing the general conception of the invention described here.
