摘要:
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.

The present invention relates to a constructional material which is stable in storage and which is kept under moisture-free conditions and which comprises a substrate and a reactive one-component system which hardens on exposure to air by reaction with moisture. The present invention also relates to a process for the production of a constructional material which is stable in storage.

The new fire retardant elements are characterized in that they are foam mouldings which are elastic in the moist state and contain a liquid flameproofing impregnation, and the fire retardant elements are protected against moisture loss before installation and solidify on drying after installation. A process for the production of such fire retardant elements and mouldings which comprise such fire retardant elements are likewise described and claimed.

摘要:
This invention is concerned with polymerizable compositions, a process for producing and polymerizing such compositions and the resultant polymerization product. Compositions comprising the reaction product of polycarbodiimides and .alpha.,.beta.-unsaturated carboxylic acids are dissolved in vinyl monomers and subject to free-radical polymerization. The polymerization product may contain up to about 300 weight percent of conventional fillers.

摘要:
An ecologically harmless process for the production of stiffening materials containing hydraulic binders, for example plaster bandages, is characterized in that a hydraulic binder is mixed in pulverulent form with a reactive binder, this mixture is applied to a sheet-like material, the sheet-like material thus coated is rolled up and the setting reaction of the reactive binder is allowed to proceed before, during and/or after the rolling-up.
摘要:
In a particularly advantageous process for the production of mouldings from expandable graphite, the expandable graphite is first converted into a pre-expanded form and the latter is compression moulded in a compression moulding apparatus at temperatures below 180.degree. C. to give performs. Moldings are produced from these preforms by heating in moulds to temperatures above 180.degree. C.
摘要:
A lightweight composite material is disclosed which comprises three-dimensionally arranged fibers of at least 50 mm length provided in a thermoplast matrix. The thermoplast matrix is thermally treated to form cavities within the matrix.
