DESCRIPTION:
BRIEF SUMMARY
This invention relates to a protective and/or camouflage material, in particular protective and/or camouflage mat for protecting persons and objects against observation and/or against chemical warfare agents, such as nerve gases, and biological agents, including toxins.
In war situations it may become necessary to protect persons and objects, such as military equipment and military installations, against observation and against attack by chemical agents, e.g. nerve gases, and biological agents, e.g. microorganisms and toxins.
It is known to protect persons and objects against chemical attacks by means of gas-proof coating materials. Such materials will however be contaminated by gas diffusing into the material and after some time therethrough. Even frequent and thorough decontaminating processes are usually insufficient, and the decontaminating process is further extremely difficult because strongly basic and thus corrosive and etching reagents must be used which per se may be damaging to personnel and equipment and which are unpleasant to work with.
It is known to treat the surface of protective or camouflage material with substances capable of decomposing or decontaminating chemical warfare agents, e.g. by applying such substances contained within gel capsules to the surface of the material. This type of protection is however destroyed when mechanical affected, e.g. in case a vehicle wheel runs over the material.
It is therefore an object of the invention to provide a protective and/or camouflage material which, on one hand, offers a more efficient and durable protection and, on the other hand, is easier to keep clean than prior materials.
For that purpose a protective and/or camouflage material of the type mentioned by way of introduction is according to the invention characterized in that the material is profoundly processed, e.g. impregnated with a substance capable of decomposing and decontaminating chemical and biological warfare agents.
Due to the fact that the material is thus profoundly processed beforehand, i.e. saturated by a substance resisting chemical warfare agents, which immediately when hit by the chemical agent starts reacting therewith, the chemical agent is impeded or even prevented from penetrating the material, thereby considerably increasing the effect of protection. In comparison with said prior art practising surface treatment, it is according to the present invention ensured that the protecting effect of the material is preserved even when exposed to mechanical influences. Moreover, the decontaminating process of the material after an attack by chemical and biological agents is considerably facilitated and it may be effected by substances that are substantially softer to equipment and persons and less injurious to the environment than those hitherto used.
The substance capable of decomposing and decontaminating chemical and biological agents may according to the invention be--or contain--a composition of the enzyme type, e.g. a phosphoryl phosphatase, and/or the class of substances exemplified by ortho-iodosobenzoic acid, the oxidating properties of which give them an anti-bacterial character as well as a chemical agents decomposing character with a specific effect against H-gases (blister gases) and V-gases (nerve gases).
It has virtually been found that certain substances, in particular enzyme containing compositions or compositions based on enzymes, in particular phosphoryl phosphatases or other bond breaking enzyme compositions and/or compositions of the ortho-iodosobenzoic acid type are able to catalyze the hydrolytic decomposition and detoxification of chemical agents in the form of nerve gases, e.g. of the organo phosphor type which in chemical respect is to be regarded as phosphoric esters, and are able to oxide biological agents, including also toxins, and chemical agents, including H-gases and V-gases. If agents of the type mentioned above hit a target protected by the material according to the invention they are to a large extent neutralized before diffusing through th
