Definitions
- Pressure sensitive adhesive process for its production and use of the pressure sensitive adhesive
- the invention relates to a pressure sensitive adhesive in the form of a reversible permanent adhesive that functions over a wide temperature range.
- the invention further relates to a method for producing such an adhesive and its use.
- Pressure sensitive adhesives are known in numerous embodiments. They are used to produce an adhesive connection which is as secure as possible, but which is reversible, that is to say can be released by suitable mechanical forces, one of the bonded surfaces remaining free of residue from the adhesive.
- Pressure sensitive adhesives are known which have an approximately constant adhesive strength over a wide temperature range (-20 ° to +70 ° C). However, these pressure-sensitive adhesives are not uniformly reversible over this temperature range, that is to say they can be removed. Pressure-sensitive adhesives are also known which are reversible over the temperature range mentioned, but whose adhesive strength changes unaffectedly when the temperature changes in the range mentioned.
- the pressure sensitive adhesive according to the invention consists of 40 to 90% by weight of an aqueous dispersible first adhesive composed of one or more substances from the group of vinyl esters, natural rubber, vinyl acetate, styrene butadiene, polyvinyl isobutylene, vinyl alcohols, acrylic ester copolymers, polymethacrylates, polyacrylic acid butyl esters, acrylic styrene copolymers, acrylic vinyl copolymers
- At least one organically soluble second adhesive from the group consisting of rubber, polyvinylchloride, dibutyl phthalate, trimethyl ester, IC resins, hydrogenated aromatic hydrocarbon resins, balsamic resins, rosin resins and
- the pressure sensitive adhesive system according to the invention thus consists of two adhesives which mutually modify one another. By changing the relative proportions of the adhesives, the adhesive strength of the pressure sensitive adhesive can be adjusted over a wide range.
- the pressure sensitive adhesive according to the invention can be produced over the temperature range from -40 ° C. to +110 ° C. with a constant adhesive force and a uniform reversibility.
- the pressure-sensitive adhesive Due to the wide adjustability of the pressure-sensitive adhesive according to the invention with regard to viscosity and adhesive strength, it can be used, for example, by means of a transfer process, in particular onto a carrier, in particular cotton fiber carrier, needle fleece, carpet or other surface-rough decorative or insulating materials.
- the pressure sensitive adhesive can be applied both to a siliconized and to an untreated HDPE or PP film, which at the same time serves as an easily removable protective cover for the adhesive layer, and can be pressed in the wet or dried state with the subsequent adhesive.
- the setting of the adhesive force is preferably designed so that the tear strength of the adhesive is greater than the adhesive forces between the pressure sensitive adhesive and a component to be bonded, so that the adhesive can be detached from the component together with the adhesive.
- the adhesion to the component is determined by the electrostatic attractive forces of the organic molecules of the adhesive to one another and to the component, by the surface tension of the pressure sensitive adhesive and by the polarity between the pressure sensitive adhesive and the component surface.
- the pressure sensitive adhesive layer develops a film character, which enables the problem-free, residue-free detachment of the pressure sensitive adhesive from the component surface.
- the pressure sensitive adhesive according to the invention enables a complete recycling of cotton fiber carrier, needle fleece, carpeting or other surface-rough decorative and insulating materials serving as the adhesive, since the pressure sensitive adhesive according to the invention is on the one hand biodegradable and on the other hand can also be integrated into the recycling process for the adhesive goods.
- the pressure-sensitive adhesive according to the invention allows bonding with problematic components made of metal or plastic, for example components with surfaces made of PP, PE, EPDM, ABS, KT-primed metals, painted metal surfaces etc. All these components do not require any pretreatment in order to use the pressure-sensitive adhesive according to the invention to be glued.
- the proportion of the first adhesive is 55 to 90, preferably 55 to 60 and that of the second adhesive 5 to 40, preferably 35 to 40% by weight.
- Any thickener for example formed by ethyl cellulose, can have a proportion of 5% by weight.
- the first adhesive can consist of a mixture of acrylic acid copolymer with styrene butadiene.
- second adhesive formed from a soft resin made of natural base (for example IC resin) and latex.
- a process according to the invention for producing such a pressure sensitive adhesive is characterized in that an aqueous dispersion of a first adhesive from one or more substances from the group of vinyl esters, natural rubber, vinyl acetate, styrene-butadiene, polyvinyl isobutylene, vinyl alcohols, acrylic acid ester copolymers, polymethacrylates, Polyacrylic acid butyl ester, acrylic styrene copolymer, acrylic vinyl copolymer with an organic solution of a second adhesive from the group consisting of rubber, polyvinyl chlorides, dibutyl phthalate, trimethyl esters, IC resins, hydrogenated aromatic hydrocarbon resins, balsam resins, rosin resins, and rosin resins viscous mixture is stirred. A few minutes, for example about 15 minutes, are generally sufficient for the stirring process.
- the organic solution of the second adhesive can be 5 to 50% by weight, preferably 25 to 45 or 35 to 40% by weight, the dispersion of the first adhesive 40 to 90% by weight, preferably 50 to 70 or 55 to 60% by weight .% exhibit.
- the organic solution of the second adhesive is first produced, which can consist of two components, for example an IC resin and latex.
- the components can already be dissolved or added to the mixture in solid form.
- Polar solvents in particular butyl acetate or alcohols, are suitable as solvents.
- the aqueous dispersion preferably has a mixture of an acrylic acid copolymer with styrene butadiene and contains about 50% water.
- the organic solution prepared and a thickener are added to the dispersion with stirring.
- the Percentage by weight dispersion 79%, organic solution: 20%, thickener: 1%.
- the recipe was
- the pressure sensitive adhesives produced in this way proved to be constant with regard to the adhesive strength and the reversibility over a wide temperature range. This made it possible to bond, in particular, thermoplastic-bonded cotton fiber nonwovens, for example with a PP molded part. Since the density of the cotton fiber fleece would possibly allow the pressure-sensitive adhesive to penetrate too strongly, a cotton fiber fleece with a cover fleece of higher density is preferably used.
- the use of the pressure sensitive adhesive according to the invention avoids reject production due to incorrect application.
- the proportion of scrap production is 7 to 10% when using a non-reversible adhesive, so that considerable savings are possible.
- Bonding with molded plastic parts, as well as with painted or primed metal parts, does not require any further preparation of the component surface to be bonded.
- the pressure-sensitive adhesive according to the invention allows a practically usable, residue-free and non-destructive detachable adhesive connection of a motor vehicle body surface to an insulating and / or decorative surface part. It has hitherto been customary to provide at least parts of body surfaces, in particular interior surfaces of motor vehicles, with insulating mats and / or with decorative surface parts. For example, to improve the overall aesthetic impression, it has been known for a long time to provide interior surfaces of motor vehicle doors with linings, to arrange a headliner on the surface parts of the roof facing the passenger compartment, and to attach decorative surfaces to shelves. In order to reduce drive and engine noise as well as for thermal insulation, it is also customary to insulate the passenger compartment using appropriate insulation mats.
- Reversible composites of interior body surfaces with insulation and / or decorative surface parts are permanently produced by mechanical tacking or connecting elements such as rivets, clips or the like.
- mechanical tacking or connecting elements such as rivets, clips or the like.
- adhesives which, however, are difficult to remove. All previously known connections thus have in common that they can only be separated from one another again with difficulty and / or with the destruction of at least one of the surface parts. If parts are to be separated from one another by means of adhesive, the material of one part and / or the adhesive itself generally remains on the other part. It is therefore not possible to separate the materials used for the respective carrier parts with acceptable productivity.
- the use of the pressure-sensitive adhesive according to the invention for connecting body surfaces to insulation and / or decorative surface parts on the one hand achieves a sufficiently strong permanent adhesive strength corresponding to the respective stresses and on the other hand the adhesion between the parts connected to one another is exerted by manual tensile force one of the parts can be easily removed.
- Another advantage is that when the pressure sensitive adhesive is used, one of the two materials remains free of adhesive residues and / or material residues when separating the interconnected materials. As a result, the subsequent recycling process can also be specifically targeted to the cheapest method, which is only matched to one material at a time.
