Abstract

Water bed mattress filling consists of a slurry of 1-7% synthetic pyrogenic amorphous silic acid in water, thickened by the addn. of 0.003-1.5 wt.%, esp. 0.1 wt.% of polyethylene glycols with a mol.wt. of greater than 600 to less than 600,000 or derivs. of polyethylene glycols such as their ethers with alcohols or amines or their esters with carboxylic acids having a mol.wt. of greater than 600 to less than 600,000, or of polyethyleneimine. USE/ADVANTAGE - The filling exhibits an increased thickness effect at points where pressure or shear are applied, thus damping out undesired wave motions and wave front propogation. The fillings allow mattresses to be made without complex internal wave damping baffles in the construction, thus lowering prodn. costs, while retaining all the desired features of the water bed such as even distribution of body weight, good sleeping comfort, etc..

Description

Wasserbetten haben den Vorteil einer gleichmäßigen Druckverteilung des Körpergewichts und ermöglichen damit ein schonendes entspanntes Liegen, was für den Schlafkomfort genutzt wird.Water beds have the advantage of being even Pressure distribution of body weight and thus allow one gentle, relaxed lying, which is used for sleeping comfort becomes.

Wasser besitzt als Füllmedium aber auch Nachteile, nämlich seine Wellenbewegung und Wellenfortpflanzung, was zu unangenehmen Schwapp- und Schaukelbewegungen führt, die sich auch längere Zeit durch Reflexion an den Matratzenwänden fortsetzt. Aus diesem Grund werden zur Vermeidung dieses Effektes und zur Erhöhung des Komforts aufwendige Innenkonstruktionen verwendet, die die Wellenbewegung des Wassers absorbieren sollen. Solche Konstruktionen erhöhen jedoch den Preis und reduzieren teilweise die Vorteile des Wasserbettes. Eine Begrenzung oder Elimination dieser Wellenbewegungen ohne aufwendige Innenkonstruktion bei vollem Erhalt der Vorteile des Wasserbettes, wäre daher wünschenswert.However, water also has disadvantages as a filling medium, namely its Wave motion and wave propagation, causing uncomfortable Sloshing and rocking movements leads to longer ones Time continues through reflection on the mattress walls. Out for this reason, to avoid this effect and Increased comfort using elaborate interior structures which are supposed to absorb the wave motion of the water. Such However, constructions increase the price and partially reduce it the advantages of the waterbed. A limitation or elimination these wave movements without complex internal construction would therefore fully preserve the benefits of the waterbed desirable.

Es wurde gefunden, daß die gleichmäßige Druckverteilung wie beim Wasser bei gleichzeitiger Elimination der Wellenbewegung in Wasserbettmatratzen oder ähnlichen Behältnissen, wie z. B. Sitzkissen erreicht werden kann, wenn man Wasser mit nur geringen Anteilen von 1-7% an pyrogener Kieselsäure versetzt und die hierbei entstehende dünnflüssige Aufschlämmung durch geringe Zusätze an Polyethylenglykolen des Molgewichts von 600-<600.000, oder deren Derivaten wie Ethern mit Alkoholen, Estern mit Carbonsäuren oder mit Polyethylenimin der Molgewichte 300-<600.000 momentan zur Verdickung bringt. Durch Druck oder Scherwirkung wird diese Verdickung gesteigert und läßt sich in einen stabilen Endzustand bringen.It was found that the even pressure distribution as in Water while eliminating wave motion in Waterbed mattresses or similar containers, such as B. Seat cushions can be achieved by using water only small amounts of 1-7% of fumed silica and the resulting thin slurry due to low Additions to polyethylene glycols with a molecular weight of 600- <600,000, or their derivatives such as ethers with alcohols, esters with carboxylic acids or with polyethyleneimine of the molecular weights 300- <600,000 is currently thickening. By pressure or This thickening effect is increased by shear and can be achieved in bring a stable final state.

Beispiele:Examples: Beispiel 1:Example 1:

1l einer 15% Suspension von pyrogener Kieselsäure in Wasser (Wacker HDK, KD150, reg.WZ. Fa Wacker Chemie GmbH, München) werden auf ein Volumen von 51 mit Wasser verdünnt und mit 10g (0,2%) an Polyoxyethylenlaurylether der Molmasse von ca. 340 versetzt. Die Mischung verdickt und weist eine Auslaufviskosität von 13 Sekunden im Auslaufbecher (4mm Düse/nach DIN 53211) auf. Diese Mischung wird durch einen Blender gerührt, wobei sich die Viskosität erhöht. Die Auslaufviskosität beträgt 20 Sekunden. Diese verdickte Mischung wird in ein Sitzkissen aus Kunststoff gefüllt. Beim Vergleich des mit dieser Mischung gefüllten Kissens mit einem mit reinem Wasser befüllten stellt man fest, daß sich die Wellenbewegungen nach mechanischem Anstoß im mit der Mischung gefüllten Kissen nicht, oder kaum fortpflanzen. Bei dem mit Wasser gefüllten Kissen ist ein anhaltendes "Wellenschaukeln" festzustellen. Auch der Sitzkomfort des mit der verdickten Aufschlämmung der Kieselsäure in Wasser befüllten Kissens ist, durch den nicht vorhandenen Schaukeleffekt, besser als der nur des nur mit Wasser befüllten.1l of a 15% suspension of fumed silica in water (Wacker HDK, KD150, reg.WZ. Fa Wacker Chemie GmbH, Munich) are diluted to a volume of 51 with water and with 10g  (0.2%) of polyoxyethylene lauryl ether with a molecular weight of approx. 340 transferred. The mixture thickens and has an outlet viscosity of 13 seconds in the outlet cup (4mm nozzle / according to DIN 53211). This mixture is stirred by a blender, the Viscosity increased. The outlet viscosity is 20 seconds. This thickened mixture is placed in a plastic seat cushion filled. When comparing what is filled with this mixture You can find pillows filled with pure water that the shaft movements after mechanical impact in the the pillow filled with the mixture, or hardly reproduce. At the pillow filled with water is a lasting one Determine "wave swings". The seating comfort of the with filled the thickened slurry of silica in water Pillows are better because of the non-existent rocking effect than the only one filled with water.

Das gleiche Beispiel wurde mehrmals mit verschieden hohen Konzentrationen an pyrogener Kieselsäure (auf die Gesamtmenge bezogen) durchgeführt. Je höher die Kieselsäurekonzentration im Wasser ist, desto höher wird die Viskosität. Je höher die Viskosität wird, desto geringer ist die Fortpflanzung der Wellen.The same example has been repeated several times with different heights Concentrations of fumed silica (on total related) performed. The higher the silica concentration in the Is water, the higher the viscosity. The higher the Viscosity becomes, the lower the reproduction of the Waves.

Alle Versuche wurden mit verschiedenen Konzentrationen (0,05g-50g) an Polyethylenglykol der Molmasse 4220 Polyoxyethylenlaurylether der Molmasse 340 oder Polyoxyethylensorbitanmonostearat der Molmasse von ca. 1200 oder PEG-120 Jojobaalkohol und PEG-120 Jojobasäure oder einer 20%igen Polyethyleniminlösung als Zusatz durchgeführt, wobei der Verdickungseffekt bei allen Zusätzen eintritt.All experiments were carried out with different concentrations (0.05g-50g) of polyethylene glycol with a molecular weight of 4220 Polyoxyethylene lauryl ether of molecular weight 340 or Polyoxyethylene sorbitan monostearate with a molecular weight of approx. 1200 or PEG-120 jojoba alcohol and PEG-120 jojoba acid or one 20% polyethyleneimine solution carried out as an additive, the Thickening effect occurs with all additives.
