Definitions

  • the invention relates to a soft-abradable glue stick according to the preamble of claim 1.
  • Such glue sticks have been known for a long time and are used in particular in the gluing of paper, cardboard and other customary materials that can be glued.
  • These adhesives contain aqueous preparations made of a synthetic polymer, for example polyvinylpyrrolidone in combination with scaffolding components, for example fatty acids, which, after neutralization in the form of a soap gel, give the glue stick the necessary shape stability.
  • the synthetic polymers together with the scaffold-forming components are heated to temperatures above 50 * C, filled into appropriately designed molds and cooled, so that the mixture solidifies, for example, in a sealable sleeve and by means of a pin rotatably mounted in the sleeve can be extended or retracted during use.
  • Such glue sticks containing polyvinylpyrrolidone (PVP) are known from DE 18 11 466. Although with this synthetic polymer manufactured put glue sticks to a good length liability under ⁇ bonding result, there is a desire to replace these adhesive raw material by a cheaper because the polyvinylpyrrolidone is preferably in the cosmetic use and thus is very expensive.
  • the invention is therefore based on the object of creating an adhesive stick which comprises an aqueous preparation of a synthetic polymer having the character of an adhesive, said adhesive stick having the same good adhesive properties as the adhesive stick known hitherto and containing PVP as an adhesive and which can be produced at significantly lower cost is.
  • the sub-claims 2 to 9 and 11 represent advantageous embodiments of the glue stick and the method used.
  • the invention accordingly relates to a dimensionally stable, soft-abradable glue stick composed of an aqueous preparation of a synthetic polymer and a soap gel as a framework-forming constituent and, if appropriate, further auxiliaries, characterized in that the aqueous preparation of the synthetic polymer comprises an at least largely solvent-free aqueous polyacrylate dispersion or a solid alkaline contains soluble polyacrylate, both of which have free acid groups.
  • the invention further relates to a method for producing such an adhesive stick, which is characterized in that the fatty acids as framework-forming constituents and the polyacrylate dispersions or the above-mentioned solid polyacrylates and optionally the auxiliaries are mixed and heated to temperatures of at least 50 * C, preferably up to 90 ° C, are heated until a uniform, clear mixture has formed and then the amount of sodium hydroxide required to neutralize the fatty acids and the free acid groups of the polyacrylate dispersion or the above-mentioned solid polyacrylates is added to this mixture and homogenized, after which the mixture is poured into molds to cool to gel.
  • carboxyl groups and sulfonic acid groups are used as free acid groups in order to adjust the acid number to a range from about 30 to 300 mgKOH / g, preferably> 200 mgKOH / g.
  • C 12 -C 22 fatty acids are used as fatty acids, which after their neutralization by sodium hydroxide are present as soaps for later formation of the gel structure of the glue stick.
  • the soaps are contained in amounts of from 2 to 23% by weight, preferably 3 to 12% by weight, based on the total weight of the aqueous preparation.
  • the auxiliaries customary for glue sticks can be used in amounts of 0 to 25% by weight, based on the total weight of the glue stick.
  • These auxiliaries include dyes, color indicators, fragrances, lubricants, plasticizers, or substances which act on the moisture balance of the glue stick.
  • the glue sticks according to the invention can also contain the previously known PVP, in an amount of 0 to 99% by weight.
  • the fatty acids as framework-forming constituents and the abovementioned polyacrylates and, if appropriate, the auxiliaries are mixed and heated to temperatures of at least 50 ° C., preferably up to 90 ° C., until a uniform, clear mixture has formed, and then to this mixture the amount of sodium hydroxide required for neutralizing the fatty acids and the free acid groups of the polyacrylate dispersion or the above-mentioned solid polyacrylates is added and then homogenized, after which the mixture is poured into molds cool with gel formation.
  • acrylic acid and / or methacrylic acid and / or itaconic acid and / or maleic acid and / or their alkyl esters can be polymerized in as monomers.
  • polyacrylates are used as polyacrylate dispersions with the trade names Neocryl TW 716 A and Neocryl BT 9 from Avecia, the Netherlands. These polyacrylate dispersions contain free acid groups and their technical data are listed in Table 1 below.
  • Glycerin technically approx. 86.5%
  • polyethylene glycol 200 Pluriol E 200, BASF
  • Myristic acid (Kortacid 1499), palmitic acid (Kortacid 1698) from Akzo Novel Chemicals GmbH and stearic acid (Safacid 16/18) from Hydro Oleochemicals were used as fatty acids.
  • Sodium hydroxide is used for neutralization, and it has been found that the sodium salts of the fatty acids used lead to soap gels, which provide the best framework substances for the glue sticks.
  • the sodium hydroxide is used either as Solid substance or expediently used in about 30% solution.
  • Neocryl TW 716 A and Neocryl BT 9 specified in Table 1 are mixed with the components listed in Table 2 below, with the exception of the neutralizing agent sodium hydroxide, and homogenized at temperatures above 50 ° C., preferably 70 to 80 ° C. The neutralizing agent is then added slowly and the whole mass is saponified for 1 hour at 70 to 90 * C. A mostly clear honey-like mass then forms. After checking the acid number of the mass, sodium hydroxide is again added, if necessary, until an acid number of approximately 0 mg KOH / g is reached.
  • the amounts of polyacrylate dispersion given in Table 2 and the additives myristic acid, palmitic acid, stearic acid, glycerol, PEG 200 and NaOH relate to the total weight of the glue stick, the remaining amount being 100% by weight of water.
  • the comparative example was carried out according to a standard glue stick, which contained PVP in an amount of 22 g. This amount of PVP must be contained in at least one ready-to-use glue stick in order to achieve a good adhesive effect.
  • the solids content of polyacrylate is 15 g and 23.2 g, respectively.
  • Table 2 despite the fact that the amounts of polyacrylates in glue sticks (1) and (2) are smaller or roughly the same, there are equally good or better data for abrasion, penetration, setting time, permanent adhesion, appearance and application as obtained with the much more expensive PVP, which proves that the object on which the invention is based is achieved.
  • test methods were as follows:
  • the glue stick is applied to paper with a defined application weight of 700 g at a speed of approx. 50 cm / s over a distance of 1 m.
  • the application quantity per m can be determined from the difference in the glue stick weight before and after the application.
  • the application amount should be between 50 and 100 mg / m.
  • the penetration is a measure of the hardness of the KL stick. It is measured with a SUR penetrometer PNR 10 from Petrotest, Berlin. The glue stick is completely removed for measurement unscrewed the sleeve and placed it under the steel pin (8 g pin) so that it just touched the mass. The needle is then loaded with a weight of 47.5 g for 5 s and the depth of penetration of the needle is determined. The higher this penetration depth (in mm), the softer the glue stick.
  • the glue stick is applied to a paper strip with a defined application weight and speed. To do this, a 3 cm wide and 30 cm long paper strip is coated 3 times in succession and a second, 2 cm wide paper strip is placed over it. Then the strips are pressed together twice with a 3.3 kg pressure roller and a stopwatch is started. The glued strips are slowly pulled apart until paper tear occurs. The time until the paper tear is recorded as the setting time.
  • the gliding ability was determined purely by feeling by using the glue stick normally. Several people were included in the test.

Abstract

L'invention concerne un tube de colle d'application par frottement composé d'une préparation aqueuse d'un polymère synthétique, d'un gel de savon en tant que constituant formant le squelette et éventuellement d'autres agents auxiliaires. La préparation aqueuse du polymère synthétique contient une dispersion aqueuse de polyacrylate au moins largement exempte de solvant ou un polyacrylate solide alcalin soluble, tous les deux présentant des groupes d'acides libres. L'invention concerne également un procédé de production de bâtons de colle, selon lequel on mélange les acides gras en tant que constituants formant le squelette, les dispersions de polyacrylate ou les polyacrylates solides susmentionnés et les éventuels agents auxiliaires puis on chauffe ce mélange à des températures de 50 DEG C minimum, de préférence 9O DEG C maximum jusqu'à obtention d'un mélange uniforme limpide. Ensuite, on ajoute au mélange ainsi obtenu la quantité d'hydroxyde de sodium nécessaire à la neutralisation des acides gras et des groupes d'acides libres de la dispersion de polyacrylate ou des polyacrylates susmentionnés puis on procède à son homogénéisation. Le mélange final est coulé dans des moules où il refroidit en donnant un gel.
