초록 ▼

Process for the preparation of flameproof synthetic resin foams which comprises admixing (a) a furan resin and/or (b) a co-condensate of a furan resin with phenol and/or melamine and/or urea and/or cresol, and/or (c) a polyester, epoxy, polyurethane, acrylic, alkyd, phenoplast or aminoplast resin or a mixture thereof, with a carrier foam of an aqueous and/or aqueous alcoholic synthetic resin prepared with the aid of a foaming agent and compressed gas.

대표청구항 ▼

Process for the manufacture of plastic foams and flameproofing foams based on aqueous and/or aqueous alcoholic synthetic resins, in which the synthetic resin is foamed up by means of foaming agents and compressed gas and is subsequently cured, if appropriate using catalysts and/or reducing agents and/or oxidizing agents, and the chemical and/or the mechanical and/or the physical properties of the known foams and/or new foams are improved by new reaction systems and/or additives, characterised in that a carrier foam of urea-formaldehyde resin or a carrier foam containing urea-formaldehyde resin and at least one member from the group consisting of: a. furan resin, b. furan resin co-condensate, c. polyester resin, epoxy resin polyurethane, acrylic resin, alkyd, phenoplast resin or aminoplast resin, is formed, the carrier foam being rapid cUring, and (2) further solid and/or liquid additives are mixed into the finished but not yet cured carrier foam in one or more subsequent mixing chambers.
