Definitions

  • the present invention is characterized by the use of phyllosilicates as a component in the manufacture of polyurethanes, replacing or not part of the polyol used.
  • the silicates are abundant in the earth's crust, and 25% of the minerals belong to this class.
  • the silicates are formed by structural units containing tetrahedra represented by S104. Within the class of silicates is inserted the subclass of the phyllosilicates.
  • Polyurethane is a polymer formed by linear macromolecules which present in the chain the repetition of the urethane functional group ( Figure 1).
  • polyurethane was popularized mainly in the segments of mattresses, upholstery and automotive seats.
  • the polyurethane In the area of rigid products the polyurethane has a wide use, being able to be present:
  • Some products are used in the synthesis of polyurethanes for the purpose of modifying the final properties of this material, such as fillers and copolymers.
  • a widely used load on flexible polyurethane foams is calcium carbon, due to the following factors: cost, non-abrasiveness, non-toxicity and having light color which facilitates pigmentation.
  • copolymers Another material commonly used in the synthesis of polyurethanes are the copolymers. These give materials foreign to the polymer chain that become part of the chain because they participate in the polymerization reactions.
  • copolymers In flexible polyurethane foams it is very common to use copolymers, either to increase hardness, flexibility, tear strength or foam resilience.
  • the present invention is characterized by promoting a method of preparing polyurethane flexible foams having a homogeneous cell structure and employing phyllosilicates in percentages ranging from 1 to 70% within the polymer matrix.
  • the polyol used used in the foam formulation may be replaced, in part, by the filosilicate, which acts as a copolymer in the foam.
  • Table 1 Examples of foaming formulation with and without phyllosilicates.
  • steatite was used, but other filosilicates may be used.
  • phyllosilicate entered the formulation by replacing part of the polyol, it participates in the synthetic chemical reactions of polyurethane foams. In this way other polyurethanes, in addition to foams, may also have the polyol substituted by phyllosilicates.
  • serpentine The thermal analysis of the serpentine shows that it loses water, both from moisture and present in its structure. As heat is absorbed to release this water, this reduces the burning power of the materials with this present filossilicate. This behavior was observed in serpentinite-containing polyurethane foam firing tests. Because they have a similar structure, other filosilicates exhibit the same flame retardant behavior.
  • the polyol and the filosilicate were placed, when used, this mixture being stirred until complete homogenization. Then, the amine, the surfactant and water were added. The mixture was subjected to mechanical stirring for 30 sec. Soon after the catalyst was added (tin octoate), the mixture was again stirred for 30 seconds. The isocyanate was introduced by subjecting the reaction mass to 4 seconds of stirring. After this stirring the mixture was poured into a wooden cubic box, 32 x 36 cm in base, by 23 cm in height. After the expansion, the foams were removed from the box and left to stand for 72 h for curing, and the mechanical properties were then analyzed, which will be described below.
  • the flexible foams were submitted to four compression-decompression cycles, with 70% deformation, in order to evaluate the behavior of hysteresis and deformation at 40% (CFD40).
  • the conditions of the experiment were determined by ISO 3386.
  • the hysteresis is related to the loss of energy of the system when it undergoes a compression-decompression cycle.

Abstract

Des mousses souples de polyuréthane ont été préparées au moyen de phyllosilicates. L'utilisation de ce matériau a favorisé une augmentation de la valeur CFD40, une réduction des valeurs d'hystérésis, ainsi qu'une réduction de la capacité de combustion du matériau. Le procédé de préparation fait intervenir des phyllosilicates, utilisant pour l'obtention de la matrice polymère, un polyol, du TDI, un indice d'isocyanate contrôlé et de l'eau et du dichlorométhane comme agent d'expansion. Selon le même principe utilisé dans les mousses souples, d'autres polyuréthanes peuvent être fabriqués au moyen de phyllosilicates.
