Moreover, compressive residual strain becomes low by that the raw materials of the polyurethane foam include either an aliphatic isocyanate or a melamine derivative. The polyurethane foam according to claim 1, wherein a urethane resin of the urethane emulsion includes a hydrophilic group.
In other words, pliability is ensured. Sodium dialkylsulfosuccinate, pH 9. In particular, the aliphatic isocyanate preferably has two functional groups such as isocyanate groups. However, for example, the number of monomers may be 2 and the number of functional groups may be 2 to less than 3. When this amount of anionic foam stabilizer is added, suitable foaming is ensured and a fine cell structure is able to be formed.
However, when the formed froth is heated for drying, the bubbles disappear and a foam is not formed. Hydrophobic HDI biuret hydrophobic biuret formed from hexamethylene diisocyanatenumber of functional groups: The method for producing polyurethane foam according to claim 16, wherein the hydrophilic group of the urethane resin is at least one of a sulfonate group, a carboxyl group and a hydroxyl group.
Consequently, the use of olefin-based foam and acrylics-based foam as sheet-like packing materials and the like is not preferable. The polyurethane foam of the present invention is formed by foaming or expansion-molded from raw materials including either an aliphatic isocyanate or melamine derivative, a urethane emulsion and an anionic foam stabilizer. The following lists various aspects of the present invention. In addition, the hardness MPa of the polyurethane foams was measured.
Embodiments The following provides explanation of an embodiment of the present invention. Potassium oleate soap, pH The polyurethane foam according to claim 1, wherein hardness JIS K thereof is 0. HDI monomer monomer of hexamethylene diisocyanate The aforementioned raw materials are weighed out in the compounded amounts weight ratios indicated in FIGS.
Although it is possible to use either the aliphatic isocyanate or melamine derivative as a crosslinking agent, the use of the aliphatic isocyanate as is a crosslinking agent is preferable when considering the 64001 of the polyurethane foam as a cushioning material or packing material of electronic equipment and 601 like.
As a result, polyurethane foam having his recovery properties, namely polyurethane foam that is resistant to collapse, is realized. As has been described above, the polyurethane foam of the present invention has low density and low hardness. Packaging and distribution of goods PET film body molding technology realizes a thinner foam with a low resilience and contains additional features, such as flame-retardant properties.
Extruded polystyrene resin foam. Polyurethane foams made with alkoxylated vegetable oil hydroxylate. A high-performance shock-absorbent series with cushioning and shape traceability properties making it ideal for applications such as shoe insoles and sports pads.
POLYURETHANE FOAM AND PRODUCTION METHOD FOR THE SAME – INOAC CORPORATION
Recovery of fluorinated surfactants from a basic anion exchange resin having quaternary ammonium groups. Hydrophobic HDI isocyanurate, number of functional groups: The aforementioned raw materials are weighed out in the compounded amounts weight ratios indicated in FIGS. Mechanical systems and components for general use Textile and leather technology The polyurethane foam according to claim 6, wherein the hydrophilic group of the urethane resin is at least one of a sulfonate group, a carboxyl group and a hydroxyl group.
Ether-based urethane emulsion emulsion of urethane having ether bondspH 8, hydrophilic group: While maintaining the same basic characteristics, we have added a series with new features, like high friction, high slidability and high surface strength, through special surface treatment.
Moreover, using both of ammonium stearate and sodium alkylsulfosuccinate as anionic foam stabilizers is preferable.
CROSS-REFERENCE TO RELATED APPLICATION
In addition, the anionic foam stabilizer used as a raw material of the polyurethane foam is for ensuring stable foaming. In addition, since aliphatic isocyanates react more mildly with water in comparison with aromatic isocyanates and the like, they suitably function as crosslinking agents of a urethane emulsion.
The method for producing polyurethane foam according to claim 12, wherein an amount of the anionic foam stabilizer is 2 parts by weight to 60 parts by weight in case that an amount of the urethane emulsion is parts by weight.
High build coating compositions. The method for producing polyurethane foam according to claim 12, wherein the aliphatic isocyanate has 3 or more monomers and 3 or more functional groups.

You have no items in jie shopping cart. TM changes hardness depending on speed and offers shape traceability around body temperature. In another example of the present invention, the isocyanate group 4 of the aliphatic isocyanate 2 and a hydrophilic group such as a carboxyl group or hydroxyl group of the polyurethane molecules 12 further react, and the aliphatic isocyanate 2 and polyurethane molecules 12 are chemically bonded.
The following indicates the details of each raw material. This grade is specifically for foot rubber. Lauryl betaine, pH 7.
