Definitions
- the present invention relates to a cyanoacrylate adhesive comprising at least a 2-cyanoacrylate and polyacrylonitrile.
- the invention also relates to the use of such adhesive mixtures as an adhesive with improved water resistance and / or gap-filling adhesive bonding of substrates.
- Cyanoacrylate adhesives are reaction adhesives based on monomeric cyanoacrylic acid esters which cure anionically to give uncrosslinked polymers. In order to initiate the polymerization, the moisture present in the air or on the surfaces of the substrates to be bonded is generally sufficient. Cyanoacrylate adhesives usually contain soluble and compatible polymers and plasticizers as well as fillers for viscosity adjustment and elastification. Cyanoacrylate adhesives are suitable for bonding very different materials with and among themselves, eg. As of textiles, paper, wood, ceramics, metals, glass, plastics and skin. They are also used as a wound adhesive in surgery.
- Cyanacrylic acid-based adhesives are often referred to as instant or superglue because of their generally fast cure. Nevertheless, they are in need of improvement, especially for special applications. For example, for many applications, e.g. home or outdoor, disadvantageous that adhesive compounds based on cyanoacrylates are not permanently water resistant, but quickly soften under the action of moisture or water, so that a loss of adhesive bond occurs.
- the invention is based on the finding that by adding polyacrylonitrile to adhesives increased water resistance of the bonds is achieved.
- the invention therefore provides an adhesive mixture comprising at least one 2-cyanoacrylate and polyacrylonitrile.
- An adhesive mixture is understood to mean an adhesive, an adhesive preparation, an adhesive mixture or an adhesive composition. This is in particular a cyanoacrylate adhesive or cyanoacrylate adhesive or a cyanoacrylate-based adhesive or a cyanoacrylate adhesive mixture.
- Polyacrylonitriles are polymers, be it homopolymers or copolymers, which are the structural feature
- Polyacrylonitrile is mainly processed into textile fibers and technical fibers.
- the adhesive mixtures according to the invention have the advantage that adhesive bonds of increased water resistance are achieved in the bonding of two substrates, as they are advantageous for example in the home, garden, leisure, but also for industrial applications.
- it is for example possible to assemble dishes, glass panes for aquariums or plastic tube with the adhesives of the invention.
- Another advantage is the improved or higher durability of the adhesive joints against aggressive environments. This becomes apparent, for example, when the bonded substrates are exposed both to boiling water and to dishwashing programs of a domestic dishwasher which has been rinsed at high temperature and which additionally uses strongly alkaline dishwashing detergents.
- An additional advantage of the adhesive mixtures according to the invention is an improved gap filling capability in comparison with cyanoacrylate adhesives without polyacrylonitrile.
- the gap filling capability refers to the ability of an adhesive to close cavities and unevennesses through the adhesive bond. The gap bridging designates the distance between two substrates, over which it is possible to bond gap-filling by introducing the adhesive mixture, whereby the adhesive should harden between the substrates.
- This distance may be in the form of a gap between two planar substrates, but also in the form of substrates having an uneven surface, in which When bonding cavities are bridged, be formed.
- the degree of these improved properties depends on the polyacrylonitrile content of the adhesive mixture.
- Another advantageous property of the adhesive mixtures according to the invention consists in a higher voltage resistance.
- the bond has a higher elasticity than that of known cyanoacrylate adhesives. This is particularly advantageous in adhesions that are subject to a single, recurring or sustained mechanical stress, e.g. Vibrations, vibrations or those caused by temperature differences such as heating, stand or are exposed to it.
- the adhesive mixtures according to the invention contain a proportion by weight of 0.1 to 40 wt .-% polyacrylonitrile based on the total weight of the adhesive mixture. Unless otherwise stated, parts by weight (% by weight) in the following text are based on the total of the respective adhesive mixture. These adhesive blends have improved water resistance for many home, garden, and industrial bonding applications.
- the adhesive mixtures according to the invention have a greater gap bridging than cyanoacrylate adhesives without polyacrylonitrile.
- Particularly advantageous are those adhesive mixtures whose proportion of polyacrylonitrile 1 to 30 wt .-% is. These have a greatly improved water resistance, as well as a higher gap bridging than conventional cyanoacrylate-based adhesives. In addition, not only the water resistance, but also the resistance of these adhesive joints in aggressive environments is significantly improved. Therefore, there are adhesive bonds of this kind even when in contact with, for example, strongly alkaline, hot, aqueous solutions for a long time. In a further advantageous embodiment, the weight fraction of polyacrylonitrile 5 to 15 wt .-%. Such mixtures appear transparent as a dried bond and thus meet particular aesthetic requirements. Adhesive mixtures with a higher proportion of polyacrylonitrile up to about 25% by weight appear increasingly cloudy as adhesive formulations in larger layer thicknesses, but give largely transparent adhesive layers after curing.
- the layer thickness of an adhesive mixture is understood to be the thickness of the applied layer. However, it may also indicate the strength of an adhesive strand when the adhesive is removed from a metering system, e.g. a tube or cartridge, is applied.
- the degree of transparency of a fabric often depends substantially on the layer thickness the viewer is viewing. Since the applied layer of an adhesive is usually significantly larger than the film of an adhesive bond between two substrates, differences in the perception of the user are possible here.
- Another preferred embodiment contains up to 20% by weight of polyacrylonitrile.
- Adhesive mixtures of this specification are relatively thin and also give predominantly transparent bonds. They are therefore particularly well suited for bonding non-absorbent substrates that have even or slightly uneven surfaces. The high flowability promotes a smooth running and wetting of such surfaces by the adhesive mixture.
- Another particularly preferred embodiment contains 20-30% by weight of polyacrylonitrile.
- adhesive mixtures are viscous to pasty. Therefore, they can not be absorbed by porous or absorbent substrates. Because of their viscous flow behavior, they are particularly well suited for gap-filling or gap-bridging bonding, for example of uneven, absorbent substrates.
- Cyanoacrylate Adhesive Blends contain from 15 to 25 weight percent polyacrylonitrile. It is characterized by a particularly high durability. This embodiment is particularly advantageous when the adhesive seam is permanently or recurrently subjected to mechanical or chemical stress. The particularly high durability of the adhesive seam is a significant advantage here.
- the average molecular weight of the polyacrylonitrile is between 20 and 300 kg / mol.
- Particularly advantageous is polyacrylonitrile having an average molecular weight between 60 and 210 kg / mol or for example 85 kg / mol.
- the average molecular weight generally denotes the weight-average molecular weight ⁇ M W > (also: M w ) of the polymer, which is determined by means of common analysis methods, for example by means of GPC or the viscosity measurement according to Archibald. The molecular weights given in this application were determined by the method of Archibald.
- the bulk density that is, the weight of the lumpy, fibrous, or powdery raw material form in relation to a given volume, is dependent on the manufacturing process.
- polyacrylonitrile having a bulk density of about 0.1 to 0.8, preferably from 0.3 to 0.6, or also from 0.34 to 0.39 kg / l at a particle size of from 10 to 100 is suitable.
- / m advantageously 40 - 50 // m or even 43 - 47 // m.
- Polyacrylonitrile is particularly suitable with about 0.1-0.2 m 2 / g, more preferably 0.14-0.17 m 2 / g.
- Another method for determining surfaces is the Gasabsorbtionsmix.
- the so-called BET surface area of a particularly suitable polyacrylonitrile is preferably less than 50 m 2 / g, in particular less than 38 m 2 / g or less than 30 m 2 / g ,
- polyacrylonitrile is added as a powder and / or in fiber form.
- the addition in powder or fiber form allows for accurate metering and even distribution during mixing.
- Polyacrylonitriles are in principle also in any other form, e.g. lumpy or as granules, for incorporation into cyanoacrylates suitable for an adhesive mixture according to the invention.
- the polyacrylonitrile is dissolved in the adhesive mixture, colloidally dissolved or dispersed.
- Polyacrylonitrile has a good mixing behavior with cyanoacrylates.
- the polyacrylonitrile in the adhesive mixture may be either dissolved or colloidally dissolved or dispersed.
- colloidally dissolved it is generally understood in polymers that parts of the polymer are solvated by the medium (solvent), other ranges again not be completely penetrated. Macroscopically, liquids are pooled under colloidal solutions that appear cloudy to the naked eye.
- polyacrylonitrile may be dispersed in cyanoacrylates.
- Dispersions are understood as systems consisting of several phases, of which at least one is dispersed continuously (dispersion medium) and at least one further is dispersed (dispersed phase).
- dispersions can consist of immiscible, liquid phases, but also of finely divided, solid phases in a liquid phase, or a mixture of several, compatible liquid phases.
- the form of the solubility of the polyacrylonitrile with respect to the cyanoacrylate has no significant influence on the water resistance of the adhesive mixture according to the invention.
- a cyanoacrylate adhesive by adding polydisperse polyacrylonitrile or by adding a plurality of different polyacrylonitriles or their derivatives.
- a polydisperse polyacrylonitrile is generally understood by a person skilled in the art to mean a polyacrylonitrile which has a broad molecular weight distribution, which may also have a plurality of subdistributions. It is likewise possible to prepare a widely distributed sample by previously mixing two polyacrylonitriles of different molecular weight.
- the different polyacrylonitriles of different molecular weight can also be added during mixing, ie in the process of preparation of the adhesive. There is no need to previously mix the polyacrylonitriles.
- polyacrylonitrile derivatives are understood by the person skilled in the art to mean chemical substances or compounds which can be prepared by reacting polyacrylonitrile in a chemical reaction, for example hydrogenation, saponification, cyclization reaction or a combination of such reactions.
- Adhesive mixtures according to the invention may therefore also contain polyamines, polycarboxylic acids or carbon fibers and intermediates of the reaction of the polyacrylonitrile via a cyclization reaction and a dehydrogenation to carbon fiber.
- the adhesive mixture according to the invention may contain a proportion of fillers, for example glass powder, glass powder, glass hollow spheres, glass fibers, finely divided silicas or graphite.
- the adhesive mixture according to the invention comprises at least one filler of amorphous, highly dispersed, i. finely divided silica. This can be added to a presented mixture of cyanoacrylate adhesive and polyacrylonitrile, but the individual components can also be mixed together in any order.
- fumed silica appears to further improve the stress resistance of the bond, such that these bonds are susceptible to thermal or mechanical stress, e.g. Vibrations, vibrations or those arising from temperature differences or heating, are highly resistant.
- the viscosity or the pasty nature of the adhesive mixture can also be influenced in a targeted manner by the addition of highly dispersed silicon dioxide.
- the proportion by weight of the amorphous silicon dioxide is 1 to 40% by weight, in particular 1 to 30% by weight, based on the total weight of the adhesive mixture.
- the proportion of fumed silica it is possible to observe a growing dielectric strength or an increasing elasticity of the bond.
- cyanoacrylate adhesives have particularly good mechanical properties, in particular excellent cohesion.
- the BET surface area of the amorphous silica is 10 to 250 m 2 / g, particularly preferably 30 to 90 m 2 / g.
- the BET surface area of 10 to 90 m 2 / g preferably from 30 to 70 m 2 / g or also, for example, 45 to 55 m 2 / g. This, for example, available under the name Durasil, has a significantly lower BET surface area.
- silica grades with a high BET surface area have a strong viscosity-increasing effect
- this silica has a lower BET surface area Contrary to the highly dispersed silicas with a high BET surface area only a small influence on the viscosity of the adhesive mixture.
- This low BET surface area silica makes it possible to adjust the processing time (correction time, correctability) over the added amount of silica.
- glass adhesives instead of the usual butyl cyanoacrylate, for example, 2-ethyl cyanoacrylate can be used, which reacts too quickly in combination with the commonly used types of silica.
- silica soot is commercially available as silica soot.
- This is a product which is obtained in the production of quartz glass and has a surface corresponding to BET of 50 ⁇ 10 m 2 / g.
- This silica is highly pure (SiO 2 content> 99%), has a pH of about 1 to 7, preferably 2 to 5 or even 3 to 4.
- Silica Soot is used as a filler for silicone rubber sealants use.
- the 2-cyanoacrylate is selected from the group consisting of methyl, ethyl, chloroethyl, n-propyl, i-propyl, chloropropyl, allyl, propargyl, 2-butenyl, phenylethyl -, n-butyl, sec-butyl, iso-butyl, tert-butyl, n-pentyl, 1-methyl-butyl, 1-ethyl-propyl, neo-pentyl, n-hexyl, 1 Methyl pentyl, n-hexyl, n-heptyl, 2-ethylhexyl, n-octyl, n-nonyl, oxononyl, n-decyl, n-undecyl, n-dodecyl, cyclohexyl , Benzyl,
