Electrieally conductive paint REUTER 45275 The present invention relates to electrically conductive coating materials herein designated as conductive The term used herein relates to pigmented paints comprising a b inder and suitable such pigments consisting mainly of a metal powder silver or copper of carbon type solid for carbon raphite or the metal or carbon particles contact each other to an electrically conductive afte application of the conductive paint on a support followed by Conductive paints known until now had considerable especially as regards their resistance to ageing and their stability against eracks caused by ture differences upon connection with an electric a composition suitable for forming an electrically conductive layer on or television tubes containing a conductive an alkali metal a water soluble and dispersible organic resin material and up to an alkali metal salt of an carboxylic acid is known from Dutch Patent Specifica ion The coating formed such known compositions is subjected to hardening at a temperature 250 to The metal salt the organic carboxylie acid contained in said composition permits formation of a porous layer through which the gaseous compounds formed during the heating can so as to permit hardening of the It is an object of the present invention to provide a conductive paint which does not has a certain degree of elasticity and need not be hardened at high It has surprisingly been in accordance with the present that excellent conductive paints t are obtained if a is used as a Thus the invention consists in a conductive paint comprising electrically conductive particles and a wherein the binder consists of an aqueous dispersion containing up to a plastics material in an aqueous silicate solution containing the ratio between the aqueous dispersion and the aqueous solution being about Preferably the aqueous silicate solution is a sodium silicate As dispersion a plastics material there can be used for the purpose of this invention any dispersion of a plastics material which does not coagulate when admixed with the strongly alkaline silicate For producing a eonductiee paint in accordance with the present invention an aqueous dispersion of an acrylic resin containing electrically conductive particles is mixed with an aqueous solution of or sodium silicate and with an aqueous dispersion of carbon the viscosity of the dispersion of the plasties material being suc as to form an easily brushable The acrylic resin dispersion added the silicate solution like the silicate for binding the electrically conductive imparts a certain elasticity to the film elasticity is desirable because during the heating up within 10 from to considerable temperature differences and mechanical stresses appear in the It has been found that a in accordance with the present invention is especially suitable for withstanding such sudden temperature so that especially the conductivity of the film formed after application of the conductive paint when using as a heating is favourably influenced at the startin addition to the preferred dispersions of acrylic resins those containing pol tetrafluoroe h lene may also be The electrically conductive particles contained in the conductive consis of for black of noble metals or of other metals or plated with noble Preferably carbon especially carbo black obtained from for of the type which is commercially available in the of an aqueous dispersion is used in the present I the conductive paint is to be used for the production of a heating it is necessary to apply it on a support and then after drying it to connect the so obtained heating film with at least two The task of the electrodes to produce between them a resistance uniformly distributed over the whole conductive When an electric current is applied to these a homogeneous voltage potential is formed between the electrodes owing to the resistance of the The electrodes may made flexible metal strips for of copper lined plasties Especially suitable for the purpose of the present invention are electrodes produced in the manner described The conductive substance used is not a powder obtained from solid but a powder of copper which is commercially available and whose particle size is about Metal other than those plated with noble are not For producing the electrodes copper powder particles having a particle diameter of about are added under continuous stirring a aqueous dispersion an acrylic The amount of powder added is such that the mixture obtained is just brus As the relatively large metal powder particles show large stices between their tangential points of a aqueous dispersion of carbon black is added to this dispersion of carbon black containing of electrically conductive acetylene carbon black particle fills the existing free spaces completely with carbon black particles after the carrier liquid has In this manner the interface resistance of the metal particles is considerably electrode mixture consists preferably of 80 parts by weight of a dispersion of a mixed polymer obtained from vinyl acetate and acrylic 100 parts by weight of copper powder and 100 parts by weight of a dispersion of acetylene carbon In addition to the use of the conductive paint according to the invention for the production of heating this paint can also be used in a series of other for as electrostatic protection for the elimination of static or as electric protection against electromagnetic high frequency invention is illustrated but not limited by the following EXAMPLE For the production of conductive paint a mixture of 100 parts by weight of a solution of potassium silicate silicate containing of dry substance and of with a ratio of and 80 parts by 6
