The invention relates to novel compositions for fire-protection agents for materials, to a method for treating materials for protection against fire, and to the use of the compositions as fire-protection agents. More precisely, the invention relates to compositions for a fire-protection agent, such as a fire-protection paint, for materials, characterized in that ceramizing additives and volume-builders are contained as ingredients.

Composition for a fire-protection agent for materials and fire-protection method

New ferrocene derivatives with the general formula: ##STR1## are described with X=H or OH

Ferrocene derivatives

A solid propellant for rocket propulsion systems or gas generators compri 35 to 80 wt. % ammonium nitrate (AN) in pure or nickel oxide, potassium or cesium nitrate phase-stabilized form (PSAN) with an average particle size of 5 to 200 .mu.m, 15 to 50 wt. % of a binder system of a binder polymer and an energy-rich plasticizer, as well as 0.2 to 5 wt. % of a burning moderator of vanadium/molybdenum oxide in the form of an oxide mixture or mixed oxide.

Solid propellant based on phase-stabilized ammonium nitrate

5 A solid propellant for rocket propulsion systems or gas generators compri 35 to 80 wt. % ammonium nitrate (AN) with an average particle size of 5 to 200 .mu.m, which is phase-stabilized (PSAN) by chemical reaction with Cu0 or Zn0, 15 to 50 wt. % of a binder system of a binder polymer and an energy-rich plasticizer, as well as 0.2 to 5.0 wt. % of a burning moderator of vanadium/molybdenum oxide as an oxide mixture or mixed oxide.

A stable, nitrogen-rich organic compound in the form of diguanidinium-5,5zotetrazolate having the empirical formula C.sub.4 H.sub.12 N.sub.16, is with a pulverulent, chemically stable oxidizer as a pyrotechnic mixture for spontaneously generating environmentally friendly, non-toxic gases.

Stable, nitrogen-rich composition

A binder composition for injection moulding or extrusion of metallic or cmic powders in sintering technology comprised 30 to 90% by weight PVA with an average molecular weight of 35,000 to 1,000,000 and 10 to 70% by weight PEG with an average molecular weight of 500 to 50,000 as the melt softener and processing plasticizer. The PEG can be wholly or partly replaced by prepolymeric, aliphatic polyesters of adipic acid and PEG with an average molecular weight of 2,000 to 20,000 or by hydroxy-terminated copolymers of ethylene and propylene oxide with the same average molecular weight.

Binder for metal or ceramic powder

A method of joining wood material and plasstic material. An anchoring layer is applied to the area of the wood material that is to be joined to the plastic material and adhesively joined to the respective area which has a high specific surface area and with which the plastic material is joined by injection molding. The resultant composite material can be used in particular in the furniture sector and in housing construction, where low-cost and stable veneered plastic parts can be produced by the method, which can be made fire-proof by using appropriate plastic materials. Additional fields of application are the automobile industry, the construction of campers and boats, and aircraft construction. The wood material that is mainly used is veneer wood, because of the high quality of the visible surface of the composite.

Method of joining wood material to plastic material

Solid rocket fuels with a low pressure exponent and with little or no sigure comprise high-energy nitramine compounds in an amount of 50-90% by weight, an azide group-containing, high-energy binder system of polymers and plasticizers in an amount of 8-50% by weight and heavy metal catalysts in the form of lead, tin or copper compounds in an amount of 0.5 to 10% by weight.

Solid rocket fuels

A method for the surface modification of objects made from polyvinylidene fluoride by dehydrofluorinated of the surface of the objects. The dehydrofluorination is carried out with an etching solution which, in addition to a strong basic compound and a swelling agent and/or solvent for polyvinylidene fluoride, contains an auxiliary agent for the homogenization of the etching solution. The effect of etching is supported by an adhesion promoter. High resistance to shearing and good tough-elasticity in composite structure and laminates is achieved.
