Definitions

• An adhesive composition for floor coverings particularly, though not exclusively for reinforced textile stair carpets comprises one part of contact adhesive components which are sticky at room temperature, and which bring about an adhering effect, and one part of synthetic thermoplastic components which are nonsticky at room temperature, but which, however, on heating to a temperature above 60 C. suffer temporary partial loss of their cohesion and become a strong sealing adhesive, which is adapted to form a permanent bond with the base to be bonded.
• the present invention concerns an adhesive composition for floor coverings, particularly, though not exclusively for reinforced textile stair carpets.
• Floor coverings are known which are held in place by special adhesives compatible with the covering material.
• impervious floor coverings have been used with adhesives which after application have been allowed to partially set in air before the final laying of the covering
• pervious coverings have been used with aqueous dispersions of synthetic resin adhesives or solvent adhesives.
• Stairs because of their nature and the type of wear they are subjected to, present difficulties and generally special contact adhesives are applied to both the stairs and the covering, then after exposing the adhesive to air for a period of time to promote tackiness, the covering is laid.
• this method has inherent disadvantages, in that the solvent used for the adhesive is often inflammable, thus creating a fire risk, and also while coating both the stairs and the covering, it is easy to spill or splash the adhesive onto nearby easily corrodible articles.
• the adhesive composition at room temperature, is sufficient to achieve satisfactory adhesion between the covering and the floor, merely by applying pressure thereto such as might, for example, result from walking thereon.
• the cohesion of the adhesive composition of the present invention is such that no adhesive remains on the floor when the covering is removed. This is unlike most, less cohesive adhesives which, on removing the covering from the floor either separate into two layers, one remaining on the covering and the other on the floor, or more or less flow apart.
• the adhesive composition has, as well as its cohesion properties, sufficient adhesion with respect to the floor covering, in that it is deposited thereon as a fusion and consequently, the hot-tack" or the hot stickiness of the cohesive portion is utilized, in order to attain a sufficient, generally permanent, bond with the base of the carpet.
• a special sealing constituent which, at room temperatures, provides sufficient cohesion for adhesive, while, if subjected to higher temperatures, becomes sticky and loses its cohesive properties (called "hot-tack").
• the'sealing constituent has the capacity of exercising a strong adhesive force on most substances, even those which are not susceptible to normal adhesives, for example plastics of the polyolefine type, smooth metal parts or highly polished wood.
• a floor covering, coated with the adhesive composition, according to the present invention is applied to a vertical wall merely by pressing, a permanent bond will not be formed and after a time the covering will fall off.
• a permanent adhesion can only be attained by repeated pressure such as by walking on a floor covering treated with the adhesive, or by the aforementioned heating and cooling process during which sealing occurs.
• the adhesive of the present invention can be regarded as having properties intermediate between those of a contact adhesives and sealing adhesives.
• a further advantage of the composition is that if it partially loses its stickiness over a period of time at room temperature, in consequence of surface soiling, becoming dusty or picking up floor particles, such as gravel, concrete or wood splinters, it can easily be reactivated again by heating to a temperature between 60 C. and the melting point of the adhesive or the fibers. Rebedding of the adhesive composition takes place causing the contaminants to resettle and become harmless.
• a typical composition, according to the present invention, of a combined fusion, contact and sealing adhesive is given in the following nonlimiting example.
• said second component being a pressure sensitive adhesion means causing a second degree of adhesiveness at room temperature
• said second degree of adhesiveness being a cold tack releasable adhesion on a surface to which said covering material is to be secured, and said first degree of adhesiveness being a nonreleasable hot tack adhesion on said surface.
