Embodiment Construction

[0024] The ceramming compositions of the present invention provide fire-retardant properties at high temperatures caused by fires. The ceramming composition comprises a mineral silicate (optionally with other inorganic fillers) and an inorganic phosphate which, together with the mineral silicate, forms a bonded ceramic at high temperatures caused by a fire. At elevated temperatures resulting from a fire, the phosphate component initially forms a liquid phase, preferably at a temperature below the decomposition temperature of at least one of the other gas generating components. A dispersed gas phase is formed due to the decomposition of organic polymers and other components such as ammonium polyphosphate. When the temperature of the composition is raised above about 800°C, the composition forms a ceramic comprising an inorganic phosphate component and a mineral silicate. The inorganic phosphate and silicate components (especially the magnesium silicate in the silicate componen...

Abstract

The invention relates to a ceramifying composition for forming a fire resistant ceramic under fire conditions the composition comprising: (i) at least 10 % by weight of mineral silicate; (ii) from 8 % to 40 % by weight of at least one inorganic phosphate that forms a liquid phase at a temperature of no more than 800 DEG C; and (iii) at least 15 % by weight based on the total weight of the composition of a polymer base composition comprising at least 50 % by weight of an organic polymer.

Description

field of invention [0001] This invention relates to fire retardant compositions which function to form ceramics at the high temperatures produced by fire. The invention also relates to the preparation of such compositions and their use, such as shaping said compositions to form articles having the desired fire retarding properties. The present invention will be described with reference to electrical cable applications, which are a particularly preferred embodiment of the invention, however, it will be appreciated that the composition may also be used to provide fire retarding properties to various articles. Background of the invention [0002] The fire-resistant properties of building materials and maintaining power supply and communications in the event of a fire are important to the safety of residents and effective firefighting. Therefore, many countries have developed performance standards for buildings in the event of fire. For example, cables used in critical applica...
