[0096] Production of starch glues 1 to 10 (SL-1 to SL-10)

[0097] The starch used comes from, for example, wheat, maize, waxy maize, potato, potato amylopectin, tapioca, rice or pea and is used as such without modification or can have been chemically or enzymatically treated according to generally / generally known methods. promotion or physical modification.

[0098] Starch glue is produced according to the Stein-Hall method from a mixture of gelatinized starch (so-called primary starch) and ungelatinized starch (so-called secondary starch). Gelatinization of nascent starch was achieved in a VMA-Getzmann Dispermat dissolver with a 6.5 cm diameter dissolution disc. The water used was heated town water1 or a mixture of service water1 and industrial water1 (industrial water pH: 6.9, industrial water conductivity: 3.6mS / cm), which was initially charged into a 1L stainless steel container. The nascent starch was agitated and, after blending with the aqueous sodium hydroxide amou...

Embodiment 97

[0166] Spray 250 g with 5.36 g of the additive composition of Example 19 (dry matter content 47%) 210, and finally mixed with the additive composition under agitation. The starch mixture thus obtained was used without further treatment.

Embodiment 98

[0168] Starch glue was prepared according to the SL-3 protocol, except that 76.3 g of the starch mixture of Example 97 was used instead of Starch 2 and the additive composition. The parameters Lory viscosity, gel point and tack correspond to those of Example 72 (Table 10).

Abstract

The invention relates to the use of an additive composition in the form of an aqueous solution or dispersion having a solids content in the region of 5 to 75 % in wt. with respect to the total weight of the additive composition, obtained according to a method consisting of mixing the components a) and b) in an aqueous medium, wherein a) is selected from sodium zirconium carbonate, potassium zirconium carbonate, ammonium zirconium carbonate and mixtures thereof, b) is selected from at least one ortho-phosphate, at least one condensed phosphate, salts thereof and mixtures as additives in starch glue.

Description

Background of the invention [0001] The present invention relates to the use of zirconium-containing additive compositions in starch glues and to the use of such added starch glues in the manufacture of paper, cardboard, corrugated fiberboard and paper sleeves the use of. [0002] current technology [0003] Starch gums or starch pastes are known in the prior art as aqueous additive compositions comprising starch and / or starch derivatives, with or without dextrin and other additives. Starches, starch derivatives and dextrins are cheap, readily available and renewable raw materials. Starch glue is an important adhesive for paper-based products and other porous substrates in many industrial applications, especially in the packaging industry. For example in the manufacture of cardboard sleeves or corrugated board, starch glue is used in paper processing to adhere the final paper-based product. A particular requirement for starch glues is tack, ie a high level of adhesion betwe...
