Description

Sept. 27, 1966 F. STREIT SEPARABLE BOND ASSEMBLY Filed April 12, 1961 INVENTOR 545D Srm-v T BY M ATTORNEY United States Patent 3,275,469 SEPARABLE BOND ASSEMBLY Fred Streit, Fords, N.J., assignor, by mesne assignments, to Peelbond Products, Inc., South Hackensack, NJ., a corporation of New Jersey Filed Apr. 12, 1961, Ser. No. 102,413 3 Claims. (Cl. 117-76) The present invention relates generally to improvements in bonding systems, and it relates more particularly to an improved separable bonding assembly.

It is very often desirable to effect an adhesion between a pair of bodies which may be broken without damage to the bodies and thus permit their separation. Examples of where this type of adhesion may be advantageously employed is in the application of Wallpaper, posters, labels, and the like, to a base substrate such as a wall, billboard, or bottle, respectively. When webs of the above nature are applied to the base substrate, a settable adhesive is usually employed, commonly of water based or water sensitive variety such as the starch pastes and glues. The removal of the web from the base substrate, such as in cases where it is desired to repaper a wall or apply a new poster to a billboard is a tedious, time and labor consuming, and hence expensive, procedure frequently resulting in damage to the stripped web or to the base surface or to both. Moreover, the stripped web is generally of no further use, and parts of the web remain adhered to the base surface to impair the appearance of the base as well as subsequently applied webs. The use of a pressure sensitive adhesive has been suggested and resorted to but this expedient possesses numerous drawbacks and disadvantages. The stripping properties of the bond is dependent upon the tackiness and elongation of the adhesive which are sensitive to many difiicult to control variables. Furthermore, the pressure sensitive adhesives are relatively expensive and frequently difficult to apply. It is apparent from the above that the conventional procedure of adhering webs to base surfaces possesses numerous drawbacks and disadvantages and the strippable bonds heretofore proposed leave much to be desired.

It is therefore a principal object of the present invention to provide an improved separable bond assembly and an improved method of producing the same.

Another object of the present invention is to provide an improved separable bond assembly of high stability and an improved method of producing the same.

Still another object of the present invention is to provide an improved separable bond assembly employing an aqueous adhesive wherein the force required to rupture the bond may be varied within wide limits.

A further object of the present invention is to provide an improved strippable web and an improved method of producing the same.

Still a further object of the present invention is to provide an improved aqueous adhesive based strippable paper web in the form of a wallpaper, billboard, poster, label floor covering, adhesive tape, and the like, and an improved method of producing the same.

Another object of the present invention is to provide an improved article of the above nature characterized by its versatility, low cost, and ease of application.

The above and further objects of the present inven-' tion will become apparent from a reading of the following description taken in conjunction with the accompanying drawing wherein:

FIGURE l is an enlarged sectional view of a strippable paper web according to the present invention, illustrated as applied to a base surface and being partially stripped therefrom; and

cionate, and others.

Ice

FIGURE 2 is a block diagram illustrating the improved method of producing the subject web.

In a sense, the present invention contemplates the provision of a separable bond assembly comprising a layer of a hydrophobic material having a substantially non-volatile water penetrant agent dispersed therethrough, and an aqueous adhesive superimposed upon and penetrating said layer. It has been found that the zone in the region of the interface of the water penetrant carrying hydrophobic layer and the adhesive is a zone of weakness defining the separating or stripping zone and that the rupturing strength of this zone may be varied within wide limits. The bond strength of the stripping zone is advantageously less than the cohesive strength of the adhesive and of the penetrant carrying hydrophobic layer and less than the bond between the adhesive and the penetrant carrying layer and their respective opposite substrates.

When the term water penetrant is employed, what is meant is a hydrophilic emulsifier, wetting agent or mixture thereofland the term aqueous adhesive designates the water based adhesives and the water sensitive or actuated adhesives. Among the aqueous adhesives which may be advantageously employed are the glues such an animal and fish glues as Well as other protein type glues, the starch based pastes, synthetic and natural resin and resin based aqueous emulsions, and the like. Examples of water penetrants which may be employed to advantage are polyvinyl alcohol, Span (sorbitol fatty acid esters, for example, sorbitol esters of monolaurate, monopalmitate mono and poly oleates and stearates), Tween (polyoxyethylene derivatives of the sorbitol fatty acid esters, such as listed above), Cellulosize (hydroxyethylcellulose), non-ionic detergents, sodium sulfosuc- The layer hydrophobic material is advantageously a synthetic organic thermoplastic resin and in a fused continuous state. Examples of preferred thermoplastic resins are the polyacrylics and modified polyacrylics, polyvinyl acetate homopolymers and copolymers, polyvinyl acetate-acrylic terpolymers, the polyolefins such as polyethylene and polypropylene, and the halogenated polyolefins, polyvinyl chloride and copolymers therewith. In addition to the hydrophobic resin and the Water penetrant, the penetrant carrying hydrophobic layer may include waxes, fatty acids, pH modifiers, glossing agents, bactericides, fungicides, dyes and pigments, etc.

The thickness of the hydrophobic layer should be suflicient to effect the bonding thereof to a supporting substrate and impede the flow of the aqueous adhesive completely therethrough when applied to the hydrophobic layer. The concentration of the water penetrant in the hydrophobic layer is such as to produce a strippable bond of the desired rupture strength. The optimum con centration of the water penetrant in the hydrophobic layer to achieve the desired bond rupture strength depends upon the composition of the Water penetrant and the hydrophobic material, and may be readily determined by one skilled in the art as may the optimum thickness of the hydrophobic layer. A hydrophobic layer thickness of between .00025 inch and .010 inch and up is highly satisfactory.

An improved strippable web, in accordance with the present invention is illustrated in FIGURE 1 of the draw-.

ing and includes a web 10 formed of a fibrous or nonfibrous material having suitably affixed to a face thereof a layer 11 of a non-volatile water penetrant carrying hydrophobic material of the nature described. The face of the layer 11 remote from the web 10 is provided with a coating 12 of an aqueous adhesive which, in turn, adheres to a base 13 onto which the web 10 is strippably all parts being given by weight:

mounted. In the region of the interface of the hydrophobic layer 11 and the adhesive coating 12 is a zone ofweakness or strippable zone 14. The zone of weakness.

14 does not penetrate the full depth of the layer 11 and its rupture strength is less than the cohesive strength of the adhesive coating 12 and the layer 11 as well as the adhesion between the base 13 and adhesive 12 andbetween the-layer 11 and the web 10. The strength of the strippable bond 14 may be varied in the manner earlier set forth.

The web may be a paper, for example any type of Kraft paper, printing paper, tissue paper, wallpaper, wall covering, paperboard,fiberboard and th'e like. Furthermore, the web 10 may be in the form of a wallpaper, band, a tape, a label, a poster, a floor tile, or of any other configuration, in accordance with the desired function or use. Theadhesive coating 12 may be carried in a dry state by the hydrophobic layer 11 and may be wetted to actuate the adhesive immediately prior .to its application to the base 13 or the wet adhesive may be applied to the base 13 before the adhesive dries.

base13 with suflicient force to rupture the weakness zone 14 and as a consequence no damage results to either the web 10 or the base 13, either ofwhich may be reused without any further preparation;

According to the improved method of producing a hydrophobic layer carrying web for achieving the subject strippable bond, an aqueous emulsion of a synthetic Torganic thermoplastic resin and a water penetrant is applied to a face of the web, dried and heated to effect the fusion of the thermoplastic materialand then cooled. A layer of an aqueous adhesive such as a glue may then be applied to the exposed face of the fused layer and dried to finish the strippable web which maybe used by merely wetting the adhesive layer and applying it to a base sur In, the alternative, the'aqueous adhesive may be face. applied in a wet state to the fused layer and the web applied to the base support before the adhesive dries substantially. V

The following example is given merely by way of illustration and is not intended to limit the scope of the present invention. v

A uniform mixture of the following ingredients is made,

. Parts Polymekon TT 1(a petroleum wax marketed by West- To the. above mixture was added 1000 parts of Catalin A1322, an acrylic copolymer aqueous emulsion containing 50% resin solids and 2% by weight of the copolymer resin of Cellulosize (hydroxyethyl cellulose) as an emulsifier (marketed by'Carbide and Carbon Chemicals Co.), and then there was slowly added to the above 500 parts of polyvinyl acetate homopolymer aqueous emul-* sion emulsified with 2% by weight of the homopolymer of Cellosize and containing 50% byiweight of the resin solids. To the resulting mixture there was then added 2.5 par-ts of sodium sulfosuccinate to complete the. coating composition for forming the penetrant carrying hydrophobic layer.

In FIGURE 2 of the drawing there is illustrated by block diagram, a method for applying the hydrophobic layer to a web 10 formed, for example, of paper or other fibrous materials, in Whifih the Web 10 is withdrawn from To separate the web 10 from the base 13 it is merely pulled from the a roll 16 and transported through a coating device: 17

While the finished web may be employed as such, it may, of course, be cut into any desired shape.
