    摘要: A novel catalyst combination for the trimerization of polyisocyanates to polyisocyanurates is disclosed. The catalyst combination comprises (i) a tertiary amine trimerization catalyst containing a dimethylamino moiety, (ii) an alkali metal salt of an N-(2-hydroxyphenyl)methyl glycine, and (iii) a monomeric epoxide. The use of these catalysts in the preparation of polyisocyanurate foams results in facile machine preparation of bun stock foam without incurring the processing problems that arise from the prior art method. The polyisocyanurate foams produced using the novel catalyst combination of the invention are characterized by a reduced level of smoke generated on combustion.

    摘要: Polyisocyanurate foams are disclosed which are characterized by low Flame Spread Ratings and low smoke generation values, as determined by the Underwriter's Laboratory Tunnel Test in accordance with the ASTM E-84 test procedure. The smoke and flame resistant properties are achieved, not through the use of flame retardants or additives, but rather by the use of a minor amount of a hydroxyl terminated aromatic polyester having a hydroxyl equivalent weight from about 150 to about 500 and which is the product of the reaction of an excess of a polyethyleneglycol having an equivalent weight from about 75 to about 225, with an aromatic polycarboxylic compound.

    摘要: Novel fire resistant insulating structural building elements are provided which are comprised of unitized structures such as walls, roofs, ceilings, and floors in combination with a layer of plastic foam insulation to which is in turn bonded a coating of gypsum plaster by a layer of bonding agent. The novel elements of the invention find particular utility in the rapid and economic construction of thermally insulated and fire resistant buildings. Additionally, a method is disclosed for a facile and economic way of providing thermal barrier protection for exposed plastic foam insulation in existing buildings by the application of a bonding agent and a plaster coat on said foam.

    摘要: A novel catalyst combination for the trimerization of polyisocyanates to polyisocyanurates is disclosed. The catalyst combination comprises (i) a tertiary amine trimerization catalyst, (ii) an alkali metal salt of an N-substituted amide, and (iii) a dibutyl tin di(alkanoate) compound. The use of this catalyst combination in the preparation of polyisocyanurate spray foams enables the systems to be sprayed in either a 1:1 or 2:1 by volume ratio, or ratios between these limits interchangably with no alterations being required in reactant formulations. The polyisocyanurate foams produced using the novel catalyst combination of the invention are characterized by having high resistance to flame and heat distortion.

    摘要: The structural strength properties of concrete and its resistance to sealing are improved by incorporating into the concrete-forming mixture an aqueous solution obtained by admixing polymethylene polyphenyl polyisocyanates with less than a stoichiometric amount of a polyethylene glycol (MW 600 to 3000) or polypropylene glycol tipped with 15 to 85 percent ethylene oxide (MW 1000 to 3500) and, within a short time of completing the admixture but during the period where said mixture is completely soluble in water, dissolving said mixture in water. Optionally, a difunctional extender is added to the solution so obtained in an amount less than that required to react with all the excess isocyanate groups.
