Description
SPECIFICATION
Fire-proofing Material for Thermoplastic and Thermosetting Synthetic Materials and Technical
Textiles or Papers
Thermoplastic synthetic materials such as for example polyvinyl chloride or polyester resin, and thermosetting synthetic materials such as for example phenol resins, and laminates or shaped or moulded members made therefrom or containing such materials, and technical fabrics or papers, are put to many uses in industry and in some cases also in the building industry or in the household. In this connection, the range of uses to which such materials can be put is restricted by virtue of their ease of combustibility. The problem was therefore that of finding a simple means, in relation to the abovementioned synthetic materials, fabrics and papers, whereby the combustibility thereof can be effectively reduced.
Accordingly, the subject of the invention is the use of a mixture comprising organic bromine compounds and organic phosphates, which is characterised in that a mixture comprising:
a) 36 parts by weight of pentabromodiphenylether
b) 40 parts by weight of an alkylaryl phosphate having the formula:
wherein
x=1 or2 n=2 to 12
R=an aryl residue
c) 24 parts by weight of tetrabromobisphenol A or hexabromocyclododecane is used for fire-proofing polyvinyl chloride, polyester resins or phenol formaldehyde resins and laminates or shaped or moulded members containing such materials, and technical textiles or papers.
In order to produce the fire-proofing preparation in accordance with the present invention, pentabromodiphenylether and an alkylaryl phosphate, for example 2-ethylhexylphenyl phosphate are firstly brought together in the required amounts and heated to a temperature of from about 1 000 to 1 200C. The required amount of tetrabromobisphenol A or hexabromocyclododecane is then introduced into the heated mixture, a homogeneous fluid material being formed, which does not change its condition even after cooling down to ambient temperature.
The fire-proofing material may be incorporated into the synthetic materials to be protected, in known manner. Thus it may be added for example to a polyvinyl chloride powder during processing on rollers or in injection moulding machines. When producing polyvinyl chloride films, the fire-proofing preparation is added, mixed with the plasticiser. Flame-resistant polyester moulding materials are produced by the fire-proofing preparation according to the invention being added to a polyester resin, together with other additives. This material is then put into moulds and processed at elevated temperature in accordance with a vacuum process or a pressing process, to form moulded components, while also using glass fibre mats or fillers. When producing phenol formaldehyde resins, the fire-proofing formulation is added to a solution of the pre-condensate and mixed therewith.This mixture is then used for impregnating technical textiles or papers which are subsequently dried, with curing of the phenol resin. Such papers may also be pressed to form hard or bakelized papers.
It is also possible for combustible materials such as for example cotton fabric to be made fireresistant directly by the fire-proofing preparation according to the invention, without also using a synthetic material. For this purpose the fire-proofing preparation is dissolved in a suitable solvent, for example toluene or methylene chloride, and the fabric or the like is impregnated with the solution. After evaporation of the solvent, a thin coating of the agent according to the invention remains behind on the substratum.
In all cases, the amount of fire-proofing preparation to be added is to be such that the synthetic material which is to be made fire-resistant contains from 1 0 to 30% by weight of the preparation, irrespective of other fillers or additives. If the preparation is used in the form of a solution for impregnating fabric or the like, from 10 to 25% by weight of the treated fabric should be due to the fire-proofing preparation, after the solvent has been evaporated off.
In the following Examples, the expression "fire-proofing preparation I and II respectively" always means the mixture according to the invention, which, for 26 parts by weight of pentabromodiphenylether and 40 parts by weight of alkylaryl phosphate, contains either 24 parts by weight of tetrabromobisphenol A (preparation I) or 24 parts by weight of hexabromocyclododecane (preparation II).
Example 1
A soft PVC. for use as film or artificial leather, which is produced in the described manner, is of the following composition:
parts by weight
Suspension-PVC 55
Dioctylphthalate plasticiser 45
Lead stabilising agent 0.5
Fire-proofing preparation 1 4.5
Antimony trioxide 2.0
A sample of the fire-resistant soft PVC complies with fire-proofing standard DIN 4102, Class B2.
Example 2
The following PVC-material is mixed together in a stirrer, to produce a fire-proofed conveyor belt:
parts by weight
Suspension-PVC 60
Dioctylphthalate plasticiser 34
Lead stabilising agent 1
Fire-proofing preparation 1 12
Antimony trioxide 8
After a homogeneous material has been formed, this is applied to a fabric insert (polyester-cotton mixture fabric) in layers by means of a doctor in such a way that three layers of the fabric are enclosed by four layers of the fire-resistant PVC-material. The coated webs are then caused to set in a heating passage. A sample of the conveyor belt complies with fire-proofing standard DIN 22118.
Example 3
A fire-proofed polyester material having the following composition is produced on a mixing roller assembly:
parts by weight
HET-acid polyester resin 100
Cobalt naphthenate 0.3
Fire-proofing preparation 11 10.0
Cyclohexanone peroxide in plasticiser 3.0
This polyester material is then used, together with glass fibres as a reinforcement, to form light plates by pressing on a heated press. These plates comply with DIN standard 4102, part 7 "resistant to flying fire and radiant heat" and French standard CSTB and British standards BS 476, part 7.
Example 4
23 parts by weight of fire-proofing preparation I are added to and carefully mixed with 60 parts by weight of phenol formaldehyde resin pre-condensate in an alcohol solution. Webs of cotton paper are impregnated with this mixture and then dried at a temperature of about 1000C. After this, 100 parts by weight of cotton paper should have absorbed 1 40 parts by weight of dried impregnation. The dried webs are then cut into sections of suitable size and the sections are laid one upon the other and pressed in a multi-layer or plate press at a temperature of 1 600C and under a pressure of 100 bars, to form 3 mm thick hard or bakelized paper plates. The plates are classified in class V-O in accordance with fire-proofing standard UL 94.
Example 5
45 parts by weight of fire-proofing preparation II are added to and carefully mixed with 36 parts by weight of phenol formaldehyde resin pre-condensate. 100 parts by weight of cotton paper is then impregnated with this mixture, dried at a temperature of 1 200C and subsequently cured at a temperature of 1 600C. The fire-proofed paper is used for making motor vehicle air filters. in the fire test in accordance with DIN 53 438, method K, it is evaluated as K1/0.5 mm.
Example 6
30 parts by weight of fire-proofing preparation II are dissolved in 70 parts by weight of toluene.
This solution is used to impregnate cotton fabrics, which are employed for example for the production of working clothing, in such a way that, after evaporation of the toluene, the weight of the fabric has increased by 20%. The fabrics comply with fire-proofing standard DIN 53 906 and DIN 54 330.
