Products of reaction of an aluminum compound (A), a boron-containing acid (B), a phosphorus-containing acid (P) and an amine (N) are characterized in that 1 mol of (A) has been reacted with from 0.3 to 1.19 mol of B, (from 1.8 to 2.19)+x mol of P and (from 0.3 to 3.69)+y mol of N, where x=from -1.5 to +1.5 and y=from 0 to 12. These reaction products may contain, if desired, up to 30 mol of water per mole of A employed and may be used in a very wide variety of ways, for example as binders, coating compositions or insulating material.

Gel formers and gels, their preparation and use

Fireproofing gels based on amine salts of acid phosphates are characterised in that they comprise an aluminium component, a phosphorus component, an amine component and if appropriate water in proportions such that, at 5 to 30.degree. C. for more than 24 hours, they form a mixture which is capable of flow, and on heating to temperatures above 45.degree. C. they change into a transparent gel in less than 24 hours. In addition to other uses, such fireproofing gels are particularly suitable for the production of laminated glass constructions having a-fire protection action.

Sandwich-like lightweight shaped articles consist of a core material containing expandable graphite expanded according to the mould and if appropriate a binder, and at least one covering layer of thermoplastic material.

Mouldings containing expanded expandable graphite are characterised in that they additionally contain acid phosphates of metals of group 2 and/or 3 of the periodic table of the elements and/or pyrolysis products thereof. Such mouldings are distinguished by the fact that they have low odour and are mechanically stable, and, when in contact with water, do not have pH values which are too low.

Mouldings containing expandable graphite, their production and their use

Improved stiffening materials containing hydraulic binders are obtained by applying a hydraulic binder, if appropriate in mixture with reactive binders, in powder form to a sheetlike material, for example a bandage fabric, compacting the hydraulic binder in contact with the sheetlike material, and winding the sheetlike material thus provided with the compacted hydraulic binder into rolls.

Polyol mixtures containing a mixture of internal mold release agents which are storage stable are made up of (a) from about 55 to about 95% by weight of a polyol mixture of (1) 30-70% by weight of at least one polyol with an OH value of more than 700 and (2) from about 30 to about 70% by weight of at least one polyol with an OH value of 700 or less than 700 and (b) from about 5 to about 45% by weight of a mixture of internal mold release agents made up of (1) from about 60 to about 95% by weight of at least one salt-like release agent and (2) from about 5 to about 40% by weight of at least one non-salt-like release agent containing an amide NH function or a urethane NH function. Known auxiliaries and additives may optionally be included. These polyol mixtures are useful in the production of rigid, semirigid and flexible polyurethane materials, particularly molded polyurethanes.
