Definitions
- the present invention relates to a method of bonding two materials with a crosslinkable adhesive. More precisely in the process of the invention there is available on the side of the material (A) which has to stick to the other material (B) a composition (A), there is available on the side of the material (B) which must stick on the other material (A) a composition (B), bringing the compositions (A) and (B) into contact with the materials (A) and (B) in the presence of heat and possibly of a pressure exerted on the materials constitutes a cross-linked adhesive that joins the two materials.
- Hot-melt (adhesive) adhesives are thermoplastic materials which are solid at room temperature and which, on heating, become viscous liquids. These viscous liquids are applied to the surface of a first substrate and then covered with a second surface. By cooling, an adhesion is obtained between the substrate and the second surface. These adhesives are designated by the abbreviation HMA (hot melt adhesives). The bondings thus produced can be used at room temperature and are sufficient. However, when they are subjected to temperatures above ambient temperature and which approach the melting temperature of the adhesive, the adhesion decreases and there is a risk of peeling.
- HMA hot melt adhesives
- Patent EP 940461 describes an HMA consisting of polyethylene in which a reactive powder and a crosslinking agent are dispersed and such that they do not react until the polyethylene is melted.
- Patent EP 326444 describes a textile covered on one of its faces with an HMA adhesive consisting of a polymer in which an encapsulated crosslinking agent is dispersed. This textile is placed on a material (for example another textile) of so that the adhesive is on the side of the material and pressure is applied while heating.
- Patent JP1249873 (application JP19880079799) describes a crosslinkable adhesive based on a blocked isocyanate and a polyamine.
- Patent EP 373878 describes an adhesive in the form of an acrylic resin modified with an aminoamide mixed with a polyol and a radical initiator. Crosslinking is caused by heating.
- Patent GB 2135673 describes a glass fabric, the fibers of which are coated with an epoxy resin, this fabric then being coated with a polyamide with amino endings. This fabric is placed between two materials that are hot pressed to cause them to stick.
- US Patent 3,409,497 describes a similar process but the fibers are coated with an OH-terminated bisphenol and the fabric is coated with an epoxy resin.
- the disadvantage of these techniques is that it is necessary either to separate the components of the adhesive well to avoid crosslinking before the bonding of the two materials or to choose the components of the adhesive well so that there is no crosslinking before a determined temperature and / or that the materials are not well placed one against the other to constitute a final assembly.
- the components of these crosslinkable adhesives are not simple products.
- the present invention relates to a process for bonding two materials with a crosslinkable adhesive. More precisely in the process of the invention there is the side of the material (A) which must stick to the other material (B) a composition (A), we have the side of the material (B) which must stick on the other material (A) a composition (B), bringing the compositions (A) and (B) into contact materials (A) and (B) in the presence of heat and possibly of a pressure exerted on the materials constitutes a crosslinked adhesive which joins the two materials.
- compositions (A) and (B) are in the form of a film, a mesh or a nonwoven.
- the film, the mesh and the nonwoven will be designated by "film” or "web”. According to a particular form the films
- composition (A) and (B) can be adjacent (and not adherent to each other) but there is no reaction since it is at room temperature.
- the two films (A) and (B) can be attached with glue dots or by heating the films (A) and (B) at only a few points to make the two films integral and facilitate their handling.
- the composition (A) is fixed to the part of the material (A) which must stick to the other material (B) and the composition
- the invention is a method of bonding two materials with a crosslinkable adhesive in which the part of the material (A) which is to stick on the other material (B) is coated with a composition (A) , the part of the material (B) which must stick to the other material (A) is coated with a composition (B), bringing the compositions (A) and (B) into contact in the presence of heat and optionally pressure exerted on the materials constitutes a crosslinked adhesive which joins the two materials.
- the compositions (A) and (B) can be deposited in the molten state on the materials.
- At least one of these compositions and preferably both are in the form of film, mesh or nonwoven.
- the film is fixed on the material by a simple hot pressing without melting the film, then the two materials are brought into contact by their part coated with films and heated, possibly exerting pressure on the materials. It would not go beyond the scope of the invention if only one of the compositions was attached to one of the materials (for example the composition (A) on the material (A)).
- the process of the invention has many advantages: the materials coated with films are easily prepared, it suffices to bring the two materials possibly coated with their film into contact and to press hot to obtain bonding, the compositions (A) and (B) react irreversibly at the time of bonding, thus the thermal resistance is improved at temperatures above the melting points of the compositions (A) and (B) alone, it is possible to choose compositions (A) and (B) which have respectively good adhesion to materials (A) and (B).
- the present invention also relates to each of the materials coated with the film (A) or (B) as well as the object resulting from the bonding of the materials (A) and (B).
- materials (A) and (B) can be any material such as wood, paper, cardboard, metal, plastics and woven or nonwoven textiles. .
- the invention is particularly when at least one of the materials is a textile.
- compositions (A) and (B) all the compositions which can be deposited in the molten state on the material or which can be filmed and which by contacting them hot produce a crosslinked adhesive are thus designated . Mention may be made, for example, of the usual HMAs provided that they each have functions which cause crosslinking.
- the melting temperature of compositions (A) and (B) is of the order of 60 to 150 ° C.
- the compositions (A) and (B) are polymers or mixtures of polymers. They can be in the form of film, mesh or nonwoven.
- the film can be made by the usual techniques of thermoplastic polymer technology, namely extrusion blow molding and "cast", that is to say that the molten material is extruded in a flat die and the polymer is cooled and solidified by passage over cooled rollers.
- the nonwoven can be produced according to the usual techniques from compositions (A) or (B) which have been put in the form of fibers. For example, the compositions are passed in the molten state in dies and the fibers are recovered on a cold plate, the contact of the fibers with each other before their complete cooling binds them together and forms a nonwoven.
