Description

(54) FLAME-RESISTANT SEALING COMPOSITIONS (71) We, HERBERTS GMBH., a body corporate organised according to the laws of the Federal Republic of Germany, of 25 Christbusch, D-5600, Wuppertal 2, Federal Republic of Germany, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- The present invention relates to sealants.
Flame resistant paints forming an insulating layer are known. They are applied as normal paints on to construction pieces of steel, concrete or wood, and in the event of fire, they form a porous, inflated, heat insulating layer which retards the heating of the substrate such that the stability of steel or concrete parts is lost much later than that of unprotected pieces and the combustion of wood is delayed. However, such paints are suitable for the protection of plane surfaces only.
Various systems which are intended to provide fire-resistant sealing of joints, for example expansion joints in ceilings, or for securing openings or cavities, have been proposed. These include, for example, glass fibre laminates, combinations of glass fibres or foamed plastics granules bound by butyl rubber strips (British Patent Specification No. 1,080,170), sealing compositions made from reaction products of sulphur with diphenyldithiophosphate and styrene (French Patent Specification No.
1,502,687), and vulcanized silicon elastomers (Japanese Patent Specification No. 094,385).
To some extent, however, these compositions are only suitable for sealing gaps, and not for securing large cavities.
Although they have the common property of being flame-retarding or nonflammable, they do not form any insulating layer on combustion and they become brittle and lose their adhesion, so that a secure seal is no longer ensured.
We have now discovered a sealing composition which forms an insulating layer and which does not embrittle over a long period of time. In the event of fire, the sealed gaps and cavities remain fire-proof and smoke-tight.
The present invention provides a sealing composition which comprises one or more substances which have heat insulating properties, for example ammonium polyphosphate, melamine, pentaerythritol or starch or a mixture of any two or more of these compounds, and a binder which comprises: (i) a vinyl chloride copolymer having a K value greater than 60, or a mixture of two or more such copolymers, and (ii) a chlorine-containing polymer which is not a vinyl chloride copolymer or is a vinyl chloride copolymer having a K value in the range of from 50 to 60, or a mixture of two or more such polymers, and (iii) at least one plasticizer which is capable, in the quantity employed, of dissolving and gelling the mixture of polymers (i) and (ii), at the temperature at which the ingredients are mixed, and (iv) at least one plasticizer which does not dissolve the mixture of polymers (i) and (ii).
In addition, the binder may comprise any suitable stabilizer for the polymer mixture, or a mixture of stabilizers, for example an organic tin compound, or a mixture of such compounds.
A sealing composition of the invention may also comprise one or more inorganic fillers, for example calcium carbonate, barium sulphate, glass fibres or other mineral fibres or a mixture of two or more of these fillers. Such fillers affect the ease of processing and the stability of the composition.
Suitable vinyl chloride polymers (i) and/or (ii) are, for example, copolymers of vinyl chloride (VC) and maleic acid esters, especially dibutyl maleate, or vinyl acetate (VAC), which are commercially obtainable as raw materials for the lacquer and plastics industries. Another suitable chlorine containing polymer (ii) is, for example.
polychlorobutadiene.
Suitable plasticizers (iii) which dissolve.
and gel the polymer mixture are, for example, aliphatic or aromatic esters of phthalic, adipic, benzoic, sebacic or phosphoric acid or a mixture of two or more such esters, or relatively non-volatile, chlorinated paraffins having a chlorine content of at least 50one Phosphoric acid esters and halogenated hydrocarbons which act against the flammability of the composition are preferred.
Suitable plasticizers (iv) which do not dissolve the polymer and tend to exude and which help to maintain the composition in a durable plastic state are, for example, nondrying fatty acid esters, for example castor oil, chlorinated paraffins having a chlorine content of substantially 40% by weight trichloro-ethyl-phosphate, mineral oils, or dibenzyltoluene, or a mixture of two or more such compounds.
The sealing compositions of the invention need not contain any volatile substances.
They have good adhesion to smooth substrates. They may be applied manually or by a blow gun; in the latter case, the application temperature should not exceed about 90"C.
The period of fire resistance of a sealing composition of the invention according to German Industrial Standard DIN 4102 is longer than 90 minutes. During a fire, the composition forms a heat insulating, mechanically stable protective layer consisting largely of carbon cells filled with gas. This layer is non-flammable. It protects the substrate material from heating and forms an efficient barrier against the penetration of smoke gases.
The following Examples illustrate the invention. All Figures given are parts by weight and percentages are by weight (except the K values, which are purely numerical).
