We have developed molding compounds from cement in combination with a nylon or polyester resin. We form the resin in the presence of the cement. We can use these molding compounds to form molded articles which have good fire resistance.

Molding compounds

A reaction product between propoxylated aniline, formaldehyde and diethanol amine is disclosed. In another embodiment, aromatic compounds can be reacted with the propoxylated aniline in addition to the formaldehyde and diethanol amine. The resulting product can be reacted with an alkylene oxide to produce a polyol which can be employed in the production of polyurethane foams.

Aniline based reaction product

We have developed new and useful epoxy resins which have excellent fire resistance. We prepare these resins by using phosphorus trihalides or phosphorus oxyhalides to cure conventional epoxy resins.

Fire resistant epoxy resins cured with phosphorus trihalides

A method for producing a phenolic molding is disclosed. The method includes the steps of mixing phenol, formaldehyde and a hydraulic cement, forming the resulting composition to a predetermined shape and maintaining the composition in the predetermined shape until an insoluble, infusible article is formed by condensation. At least 10 percent of the hydraulic cement must be Portland cement. The mole ratio of formaldehyde to phenol must be at least 1:1, and the amount of hydraulic cement must be sufficient for reaction with from 1 to 9 times the sum of the water of condensation of the phenol with the formaldehyde and the water charged to the mix. The use of reinforcing glass fibers in producing phenolic moldings is also disclosed, as well as the use of urea and resorcinol in addition to the phenol, formaldehyde and hydraulic cement.

Flame retardant polyurethane foams are disclosed. Flame resistance is achieved by a combination of at least three polyols. Control of internal exotherm is achieved by the addition to the foams of an inorganic material such as hydrated alumina.

Fire retardant polyurethane foams

Addition products of polyepoxides which have proved to be excellent flame-retardants for plastic foams such as polyurethane foams are disclosed.
