Abstract

The adhesive, for joining assembled components, has particles of a solid material with it to impart special properties. Pref. the adhesive itself can be, for example, silicone-based, and the solid particles can be in the form of glass beads, a metal or a metallised product, comprising between 30 and 70 per cent of the adhesive by volume. The dimensions of the particles are pref. 1-50 microns. USE/ADVANTAGE - Joints in electrical or electronic circuits, with components which can be joined by manual pressure. Simple and rapid making of joints, with wide range of applications.

Description

Translated fromFrench

"Produit de collage pour l'assemblage d'éléments"
L'invention est caractérisée en ce que ce produit de collage se compose d'une substance constituant un adhésif permanent mélangée à des particules solides.
"Bonding product for assembling elements"
The invention is characterized in that this bonding product consists of a substance constituting a permanent adhesive mixed with solid particles.

Suivant une autre caractéristique de l'invention, les particules solides sont des billes de verre. According to another characteristic of the invention, the solid particles are glass beads.

Suivant une autre caractéristique de l'invention, les particules solides sont des particules métalliques. According to another characteristic of the invention, the solid particles are metallic particles.

La présente invention a en conséquence pour but la réalisation d'un produit de collage qui ne perde pas ses propriétés de collage après qu'il ait été étalé sur un élément à assembler, l'assemblage par collage pouvant s'effectuer ultérieurement à une époque plus ou moins lointaine mais uniquement avec un élément également pourvu d'une couche de ce type de produit de collage. The present invention therefore aims to achieve a bonding product which does not lose its bonding properties after it has been spread on an element to be assembled, the assembly by bonding can be done later at a time more or less distant but only with an element also provided with a layer of this type of bonding product.

Ce produit de collage constitue donc un adhésif permanent qui n'est collant que vis-à-vis de lui-même ou d'un adhésif du même type. This bonding product therefore constitutes a permanent adhesive which is only sticky with respect to itself or of an adhesive of the same type.

Suivant l'invention, il est prévu de mettre en oeuvre une substance adhésive et, par exemple, à base de silicone, qui constitue un produit adhésif permanent et de mélanger cette substance visqueuse à des particules solides de dimensions suffisamment faibles et en quantités suffisamment importantes pour que le produit de collage obtenu, après avoir été étalé sur un élément, ne soit pas collant au toucher ou par contact avec un élément de nature quelconque, lui-même dépourvu de ce produit de collage. According to the invention, provision is made to use an adhesive substance, for example based on silicone, which constitutes a permanent adhesive product and to mix this viscous substance with solid particles of sufficiently small dimensions and in sufficiently large quantities. so that the bonding product obtained, after being spread on an element, is not sticky to the touch or by contact with an element of any kind, itself devoid of this bonding product.

Les particules de la charge pourront être de dimensions et de nature identiques ou non, les dimensions variant de 1 à 50 microns. The particles of the filler can be of identical dimensions and nature or not, the dimensions varying from 1 to 50 microns.

La quantité de particules mises en oeuvre variera de 30 à 70 % en volume par rapport au volume de la substance adhésive utilisée, la valeur exacte de ces proportions dépendant d'ailleurs plus de la forme des particules que de leurs dimensions. Cette quantité dépend bien entendu également de la viscosité de la substance adhésive mise en oeuvre et du fait qu'elle devra toujours être d'une consistance telle qu'elle puisse être étalée à la manière d'une peinture ou d'un produit semi-pâteux sur un support. The quantity of particles used will vary from 30 to 70% by volume relative to the volume of the adhesive substance used, the exact value of these proportions depending moreover more on the shape of the particles than on their dimensions. This quantity naturally also depends on the viscosity of the adhesive substance used and on the fact that it must always be of a consistency such that it can be spread in the manner of a paint or a semi-finished product. pasty on a support.

Bien entendu, différents produits dont les propriétés physiques et chimiques sont connues en elles-mêmes, pourront être ajoutés au produit de collage de base ci-dessus, afin d'aboutir à un effet ou à une action particulière. Ainsi par exemple, ce produit de collage pourra comporter un colorant, un solvant ou un catalyseur, ce dernier ayant pour but d'assurer la polymérisation de l'adhésif au bout d'un laps de temps plus ou moins long, après qu'il ait été étalé sur un support. Of course, different products, the physical and chemical properties of which are known in themselves, can be added to the basic bonding product above, in order to achieve a particular effect or action. Thus, for example, this bonding product may include a dye, a solvent or a catalyst, the latter having the aim of ensuring the polymerization of the adhesive after a more or less long period of time, after it has been spread on a support.

Les particules solides pourront, par exemple, être constituées par des billes de verre. The solid particles could, for example, consist of glass beads.

Elles pourront également être constituées par des particules métalliques ou métallisées, de façon à rendre conducteur ce produit de collage. They may also be formed by metallic or metallized particles, so as to make this bonding product conductive.

Ce produit peut alors être utilisé comme moyen de liaison électrique, de composants électriques ou électroniques avec un circuit quelconque ou encore pour réaliser la liaison électrique simple et rapide de parties métalliques et, notamment, des parties métalliques d'un ensemble de blindage électrique. This product can then be used as a means of electrical connection, of electrical or electronic components with any circuit, or even to make the simple and rapid electrical connection of metal parts and, in particular, metal parts of an electrical shielding assembly.

Les deux surfaces à assembler préalablement recouvertes aux endroits désirés de la substance adhésive définie ci-dessus seront, lors de l'assemblage, pressées l'une contre l'autre, étant entendu qu'une pression manuelle suffit pour obtenir cet assemblage. The two surfaces to be assembled previously covered at the desired locations with the adhesive substance defined above will, during assembly, be pressed against each other, it being understood that manual pressure is sufficient to obtain this assembly.
