Composite explosive with rubber-like Binder and process for its manufacture

The invention relates to a composite explosive with a rubber-like binder intended in particular for manufacture by casting is, and a process for its manufacture.

A composite explosive is understood to be an explosive one Mass of any shape, consisting of a uniform dispersion of explosive particles in a possibly cross-linked binder, which can also contain additives that improve the physical or detonation properties modify.

The following manufacturing processes for composite explosives are known: compression molding, extrusion or casting.

The compression molding processes are the classic manufacturing processes. Very high pressures (200 bar) are required. In these procedures, the explosives

109883/1076

particles coated with a binder and then exposed to strong pressure at different temperatures, to get blocks or slabs of explosives. The explosion processes require a less high one Pressure.

The casting processes are the most recent development; they work pressureless, but have the disadvantage that they have a perfectly defined binder composition require, which must be compatible with a difficult manufacturing technique that affects the quality of the end product essentially conditional.

To the composite explosives with rubber-like binders, which are intended for production by casting belong according to the current status Explosives mixtures with a composition in percent by weight

75 to 95 % explosive substance such as cyclonite, trinitrotolurol, pentaerythritol tetranitrate, tetryl, nitroguanitine, picric acid, nitrolactose, mannitol, mannitol octonitrate and sucrose octanitrate,
5 to 25 # of a poly silicone binder.

These explosives mixtures can be of two different types Species are produced.

In one procedure, the explosive substance and polymerizable silicone mixed, and the resulting mixed product is heated to a temperature below Brought to the point of decomposition of the explosive substance a plastic mass is obtained.

109883/1076

Another method is to heat a polymerizable silicone to form a gel of the desired consistency to obtain, and then this polysilicon gel mixed with the explosive substance to obtain the desired product.

The disadvantage of these processes is the reaction temperatures, which are always above 100 ° C. and mostly on the order of 125 to 150 ° 0 what some precautionary measures are required in the manufacturing process. Also, those obtained with these explosives are Detonation velocities less than 7000 m / s and the polymerizable silicones used are relative uneconomical raw materials. After all, the casting process does not give exact shapes and does not give the desired shape Surface fineness.

2. Composite explosives made of flexible films with rubber-like binders, which are based on a Explosive substance such as penthritol, hexogen, octogen as well an aqueous latex emulsion, the water content of which is expelled after molding will. This is done by absorption in a mold or by drying. Of course it is essential To completely expel the water, with all the risks and difficulties inherent in such an operation in terms of the quality of the end product. It doesn't matter which procedure is used being, absorption in a form or drying, it is always a difficult operation that moreover in the case of drying does not work very economically. The process usually requires a mechanical one Surface finishing to obtain the desired surface fineness, which adds to the prime cost increased and made more difficult to manufacture.

According to a further invention, the composite contains explosives a plasticizer. The usual plasticizers of polyolefins are used, such as waxes, oils, esters, such as Dioctyl azelate, also liquid polybutadienes and others. The plasticizer content is a maximum of 60 percent by weight of the binder.

Furthermore, the composite contains explosives in a special Embodiment of the invention an inhibitor (antioxidant). The usual Rubber inhibitors used, such as. B. phenols or phosphites. Polygard can be mentioned as phosphites (Nonylphenyl phosphite).

Among the phenols, MBP5 can be mentioned, which is 2,2-bismethylene (4 ~ methyl-6-tertiobutylphenol) or ionol, which is di-2,6-tertiobutyl-p-cresol acts.

The composite explosive can also contain auxiliaries, which modify the physical or detonation properties. Red lead serves as an example

In addition, the invention proposes a method for producing a composite explosive, accordingly the Explosive particles with at least one carboxylic polydiolefin and at least one agent for chain extension and / or crosslinking are mixed and the like casting compound obtained is cast, the reaction of the carboxyl polydiolefin with the chain extension agent and / or crosslinking leads to the formation of the resin binder.

The inventive method allows with the inventive Composite explosives in a direct way

109883/1076

Explosive parts of a perfectly defined shape and in any desired form To obtain dimensions that have the desired surface quality and a density that is everywhere comes close to the theoretical density. Require molded explosive parts produced by the method according to the invention so no post processing.

The process can be adapted to specific uses of the product. . .

In a preferred variation, a carboxylic polydiolefin is used used, which has a molecular weight between 1000 and 8000, a COOH equivalent between £ see 0.20 and 300 mg and at least two CQOH groups per molecule and has a viscosity between 100 and 800 poise at 25 ° C. According to the invention has the Polydiolefin used preferably only two COOH groups per molecule, which are at the ends of its main chain hang. Such a prepolymer is referred to as carboxy telechelate (Cearboxy-telechelique); with it you get End products with the best elastic properties.

According to a further invention, the agent for chain extension and / or crosslinking is selected from the group of polyepoxides selected, which may contain substituted epoxy groups.

The hallmark of these epoxy groups is that they open up through the addition of COOH groups, without slight Release molecules that have a tendency to diffuse or to form gas inclusions in the composite explosive. It is advantageous to use a polyepoxide with more than two epoxy groups per molecule.

Examples are:

- The condensation products of epichlorohydrin and polyol;

10 9 8 8 3/1076

- the epoxy compounds of liquid polybutadienes;

- epoxidized soybean oils; - ■

- the condensation products of epychlorohydrin and the ' Higher molecular weight triols;

- the epoxy compounds of the derivatives of cyclohexanevinyl;

- bis-cyclopenthadiene dioxide. .

The reaction of the carboxylic polydiolefin with the agent for chain extension and crosslinking serves to produce a three-dimensional rubber-like network, which is elastically deformable and has very little permanent deformation.

Leave the mechanical properties of the binder network Modify yourself greatly by changing the molecular weight of the Garboxylpolydiolefin changed as well as the Group number of the means for chain extension and crosslinking (the number of epoxy groups per molecule) as well as the molecular weight. -

The elasticity and softness of the binder network depends of course on the average molecular weight " the chains between the network nodes. The polydiolefins High molecular weight, the COOH groups of which are as far apart as possible, have a strong one Elasticity and a high elongation at break, you want the best possible elasticity and ductility properties obtained, then it is advantageous to use polydiolefins according to the aforementioned modification of the invention, which have only two COOH groups attached to the Hanging ends of the main chain. Such polydiolefins, which were previously referred to as arboxy telechelate prepolymers thus provide products with the best elasticity properties. Of course it depends, as before

10 9 8 8 3/1076

indicated, the ductility of the composite explosive not only depends on the properties of the binder, but also on the proportion of explosives. It is so possible to get explosive blocks and plates with different ductility *

In another preferred embodiment of the method according to the invention, the crosslinking and the Chain extension of the resin accelerated with a catalyst.

Organic metal compounds such as acetylazetonates (salts of the tautomeric (isomeric) form of acetyl acetone), metal alkyl derivatives, the salts of resorcylic acid, lauric acid, the 2-ethylhexanoic acid, a naphthenic acid (essentially Alkylcyclopenthanacetic acid), whereby the metals can be iron, lead, tin or cobalt.

The final properties of the rubber net are determined by the degree of crosslinking of the resin based on carboxyl polydiolefin certainly. This degree of crosslinking can be changed by changing the proportions of the two- or Multi-group crosslinking agents can be changed. The higher the number of reacting groups on the molecule of the crosslinking agent, the closer the crosslinking and the stiffer the resulting composite explosive.

It is advantageous to use the stoichiometric ratio * ratio between the epoxy groups of the polyepoxide and the COOH groups of the carboxylic polydiolefin between 0.8 and 1.3. By changing the stoichiometric The proportion around the value 1 is the crosslinking, the rubber-like binder and as a result

10 3 883/1076

its the elasticity and ductility properties slightly modified.

According to a further feature of the process according to the invention, a wetting agent is incorporated into the reaction mass. You can choose from the following product groups: waxes, lanolin, phosphatides such as lecithin, and furthermore some substances like SuIfimel, a -Ohlornaphtali-n. The task of these wetting agents is to facilitate the mixing and flow of the casting compound.

The reaction temperature is preferably between room temperature and 95 ° C

According to a further invention, the components of the binder are under before the introduction of the explosive substance Vacuum mixed. In this way one can obtain a composite explosive with a high proportion of charge, i. H. with a high proportion of explosives. Under the Assuming that the temperatures are relatively low, the explosives can then be used without any Mix in danger.

Instead, the constituents of the binder and the explosive substance can also be mixed together under vacuum «, There is also no risk here.

The method according to the invention therefore has an obvious advantage over conventional methods which require reaction temperatures which are relatively close to the point of decomposition of the explosive substance. In the production of composite explosives with polysilicon binders, the mixing takes place at temperatures which can reach up to 150 ° C, which some Difficulties in manufacture caused (risk of explosion).

109883/107 6

The casting compound is useful when pouring or after Pouring shaken. This operation, which can also be carried out under vacuum, aims to degas the casting compound.

According to a preferred embodiment of the invention the product at the end of the process at a temperature that ensures hardening in a tolerable time (Temperature below 95 C), poured.

The method according to the invention accordingly comprises the following Basic operations.

~ 1. The binder components are in a vacuum at a - Mixed temperature, which is always below 95 ° C.

2. The explosive substance is added, and the mass is mixed under vacuum at a temperature which in any case is below 95 ° C. (The first two steps can be combined into a single one: They become the components the binder and the explosive substance together mixed in a vacuum at a temperature below 95 ° C.)

A 3 The resulting casting compound is preferably shaken, which possibly takes place under vacuum for the purpose of degassing. (Instead, the casting compound can be used after the Potting to be shaken.)

4-, The casting compound is at a temperature below annealed at 95 C. The tempering or hardening time is several days.

109883/107 6

These basic operations limit the invention in in any way, and depending on the application, If necessary, introduce different forms of modification.

Vacuum degassing of the casting compound by shaking is a particularly important factor in the manufacture of explosive boards important stage of the manufacturing process, because it contributes to a large extent to gas bubbles or gas inclusions to be avoided in composite explosives. Also be this gives high surface quality. This has an undeniable advantage over the conventional ones Casting process for the production of composite explosives with a rubber-like binder.

The aim of the casting process according to the invention is to use the carboxylpolydiolefin-based binder directly to obtain molded parts with perfect shape and in all dimensions, which have a density of at least 99.5 % of the theoretical density at all points compared to values of 96 to 97% im Means using conventional methods. Parts produced by the method according to the invention do not form cracks and can be glued directly to the walls of the container in which they are poured, since they completely fill any volume and the shrinkage during polymerization is negligible.

The composite explosives obtained in this way are not very porous and very homogeneous in contrast to the explosives obtained by pressing processes. Your mechanical properties are analogous to rubber-bound explosives. They are not brittle, they are excellent Impact strength and favorable aging behavior. The surface quality after casting is much better than parts made by traditional casting processes

In the further description, preferred examples of composite explosives according to the invention are described. In these examples, the percentages are by weight details of explosive substance and binder, as well as the composition of the binder and the detonation rate of the end product according to the invention.

The exact weight of the polyepoxide must be determined prior to its use can be determined taking into account the specified stoichiometric relationship (in relation to the COOH groups of the carboxyl polydiolefin).
